2019 Rolex 24 DPI Preview

The only place to be as a racing driver in late January is Daytona International Speedway, for the annual Rolex 24 season opening extravaganza for the IMSA WeatherTech series.

The winter has seen substantial change, with the DPI formula cars now being given center- stage, after sharing the top class with European spec LMP2 cars for the past five seasons.

The DPI class has been given a power boost, with the cars already looking much quicker in the Roar pre-race test. The DPI class boasts an impressive eleven car entry, with factory backed efforts from Cadillac, Acura, Nissan and Mazda. The level of manufacture support shows that the class has a long-term health, with more car makers strongly rumoured to be joining the class from next year.

Let’s take a look at the eleven entries that will be fighting for the overall victory and the Rolex watch.

#5 Mustang Sampling Action Express Cadillac DPI: Filipe Albuquerque/Joao Barbosa/Mike Conway/Christian Fittipaldi 

For the #5 crew 2018 was an up-and-down year for the team. They won the Rolex 24 after narrowly missing out in 2017, yet aside from a further win in Long Beach the team struggled. Albuquerque finished the year sixth in the points, a down year for one of the benchmarks in the series for the last few years.

For this year regular driver Christian Fittipaldi is only doing the Rolex 24 before retirement, so former Audi factory man Albuquerque steps in alongside Barbosa for the full season. Regular endurance co-driver Mike Conway returns to a strong entry looking to give Fittipaldi the perfect send-off.

The team will be pleased with fourth and top Cadillac car in the Roar qualifying for pit-box and garage selection, however to be almost 0.9s back from the factory Mazda team is a slight concern. The team have a proven entry and reliable car but lady luck needs to smiling on you if you’re to win the Rolex 24 such is the competitiveness of this class.

#6 Acura Team Penske Acura ARX-05: Dane Cameron/Juan Pablo Montoya/Simon Pagenaud

The factory Acura programme instantly became a force in the IMSA series last season, with the might of Team Penske behind it this was not surprising to many. Going into 2019 the team looks increasingly formidable, with a year now behind the team to iron out any reliability issues.

Dane Cameron and Juan Pablo Montoya are the full season pairing again, with former Indycar champion Simon Pagenaud joining them for the endurance rounds. Montoya is the star name in this entry because of his F1 experience, however it’s Dane Cameron who is the hidden gem of this entry.

Seventh fastest in qualifying for deciding the pit garage/box selection will slightly hinder the team, but less than two tenths away from their team-mates in third just shows the fine margins that make a big difference in this series.

#7 Acura Team Penske Acura ARX-05: Helio Castroneves/Ricky Taylor/Alex Rossi

The #7 took the only win for Acura last season, however they were less consistent over the year when compared to their teammates. After making their debut last year the team can now go into this years Rolex 24 knowing they have a good chance of winning this race.

Helio Castroneves and Ricky Taylor return to form a very strong duo, and for the Rolex 24 have former Indy 500 winner Alex Rossi on board. Rossi is a quality signing will be very quick in the Acura, with the only knock on him being a lack of significant sportscar experience.

The team were very quick in the pre-race testing, finishing best of the rest behind the Mazda’s in the pit selection qualifying session. To be at the front of a very tightly packed field is a good result, with the only downside being the 0.8s gap to the factory Mazda duo.

acura-team-penske-livery-1-1

#10 Konica Minolta Wayne Taylor Racing Cadillac DPI: Fernando Alonso/Kamui Kobayashi/Jordan Taylor/Renger van der Zande 

The Wayne Taylor racing team created all the pre-race headlines this winter when they announced that double F1 world champion Fernando Alonso would be joining the team for the Rolex 24. He made his debut in the race last year, but this year he joins an already formidable team as he looks for his first Rolex 24 victory.

Coming off an incredible Petit Le Mans victory last October, are returning dynamic pair Jordan Taylor and Renger van der Zande. Both proved last year to be a good pairing and very quick. Completing the line-up is Toyota factory driver Kamui Kobayashi, another headline maker adding to an embarrassment of riches for this team.

The team was right in the mix at the pre-race Roar, although sixth in the qualifying session will be a slight disappointment. This team has all the ingredients to win this race, although every winner needs a clean run and a dose of luck to succeed over 24 hours against this quality field.

10-konica-minolta-cadillac-dpi-1

#31 Whelen Engineering Action Express Cadillac DPI: Eric Curran/ Pipo Derani/Felipe Nasr

The defending champions return for another crack at the Rolex 24, after being the bridesmaid behind their teammates last year. They claimed the overall championship however, along with the North American Endurance Cup.

The championship winning partnership between Eric Curran and Felipe Nasr has been broken up for 2019, with Brazilian Pipo Derani joining countryman Nasr for the full season. Curran has now been shifted to an endurance rounds only deal with the team.

The team ran well at the Roar, finishing a close fifth in the qualifying session, less than a tenth behind their teammates. The DPI class gets stronger every year in IMSA and this line-up has only improved despite winning the title last year. This entry is one of the several that can seriously challenge for victory should they not run into problems.

#50 Juncos Racing Cadillac DPI: Rene Binder/Agustin Canapino/Kyle Kaiser/Will Owen

The IMSA series is improving in quality every year, with the addition this year of Indycar outfit Juncos Racing. This is the team’s first foray into sportscar racing, however they have a very good CV from the American open wheel scene.

The team went for the proven Cadillac DPI package, and will hope to impress in their first sportscar outing. The team have brought in plenty of drivers they have experience with, starting with young driver Rene Binder. He’s hoping to impress and cement himself in America after spending years chasing the F1 dream in Europe. Will Owen will provide sportscar experience and was a former Juncos driver, as was Kyle Kaiser. Both raced for the team in the Mazda Road to Indy ladder.

The fourth and final driver is a wildcard, the Argentinian Agustin Canapino. He’s been a proven winner in various Argentinian touring car series, and will no doubt grab his chance to shine on the international stage. This is the first race for the team in sportscar so they will have a lot to learn, but they could spring a surprise if others hit misfortune.

#54 CORE Autosport Nissan DPI: Jon Bennett/Colin Braun/Romain Dumas/Loic Duval 

The surprise package of the 2018 IMSA season was this CORE Autosport team, but it’s all change for the team this year. In an unfancied LMP2 entry they came within three points of winning the series title, with Colin Braun and amateur driver Jon Bennett.

After the rules change to separate the DPI and LMP2 entries and the closure of the ESM team CORE have made the step up to take on their Nissan DPI entry for the 2019 season.  The returning duo of Colin Braun and Jon Bennett have a long history together and work very well. They are joined by Porsche and Audi factory drivers Romain Dumas and Loic Duval, further adding to the talent in this team.

At the pre-race Roar they were off the ultimate pace, being the slowest DPI outfit in the qualifying session, behind even the fastest LMP2 entry. Whilst the team have to learn the intricacies of the Nissan DPI package, the team shocked everyone last year so why can’t they do it again this year?

core-autosports-nissan-ligier-1

#55 Mazda Team Joest Mazda DPI: Jonathan Bomarito/Olivier Pla/Harry Tincknell 

The Mazda factory DPI outfit started the year slowly but improved massively as the season wore on. The team have the might of Team Joest running their programme, and for 2019 they could prove to be a good outside bet for the championship.

On the driving front Jonathan Bomarito and Harry Tincknell return for the full season, and for the endurance rounds are partnered by Frenchman Olivier Pla. All three are proven at this level as quick sportscar racers.

In pre-race testing the Mazda team stole the headlines, securing a 1-2 in the qualifying session, significantly quicker than their rivals. Whilst this may not be reflected in the race, the team certainly have everyone guessing right now as to their ultimate pace.

55-mazda-team-joest-mazda-dpi-1

#77 Mazda Team Joest Mazda DPI: Timo Bernhard/Oliver Jarvis/Tristan Nunez/Rene Rast

The 2-3 for Mazda at Petit Le Mans last year gave the team some positive direction going into the winter, and they appear to have worked hard to maintain this forward progress. Team Joest and Mazda have clearly been working hard to make themselves regular contenders in this uber competitive class.

Oliver Jarvis and Tristan Nunez return for another full season with the team, and for the Rolex 24 they have Timo Bernhard and Rene Rast joining them. Both are very quick prototype drivers who are high profile additions to the team.

The #77 car showed very well at the Roar test, setting an unofficial track record in the qualifying session. Their time was only closely matched by their team mates, showing the team have very good one lap pace. If they can stay reliable for 24 hours they will be tough to beat if they can consistently replicate their one lap pace shown at the Roar.

77-mazda-team-joest-mazda-dpi-1

#84 JDC-Miller Motorsport Cadillac DPI: Chris Miller/Juan Piedrahita/Stephen Simpson/Simon Trummer

JDC-Miller are another team that have switched from LMP2 to DPI chassis this year as they continue hunting for overall race wins. The team have taken the safest choice and are running two Cadillac DPI chassis this season.

The team’s race winning line-up from last season has been split up, with Stephen Simpson moving to this #85 entry for this year. He is joined for the year by Simon Trummer, another single seater convert looking to find a long-term home. Joining them for the Rolex 24 is experienced racer Chris Miller, along with Indy Lights convert Juan Piedrahita.

The team were one of the surprises of last year along with CORE Autosport, and for this year with a proven Cadillac DPI package and a strong driver crew the team could be contending for the podium come Sunday afternoon.

85-jdc-miller-motorsports-cadi-1

#85 JDC-Miller Motorsport Cadillac DPI: Rubens Barrichello/Devlin DeFrancesco/Misha Goikhberg/Tristan Vautier

JDC-Miller’s win at the 6 Hours of Watkins Glen last year proved they can be successful at this level after recently stepping up from the LMPC class. The switch to Cadillac DPI machinery is a big step for the Minnesota based team, and one that should bring more success for the team in the coming years.

Misha Goikhberg was very impressive last year and is paired this year with Tristan Vautier. He is a very quick and experienced racer who moves across from the Spirit of Daytona team. GP3 racer Devlin DeFrancesco returns to the team after last year and completing the line-up is star name and former longtime F1 racer Rubens Barrichello.

The JDC-Miller motor sport team proved last year they are a very well run team who can perform well in IMSA. They should have time during the winter to get used to the new Cadillac DPI package, and they have every chance to spring a deserving surprise with Rolex 24 victory.

2018 Rolex 24 Prototype Preview Part 2

Here is a look at the second half of what is an ultra competitive Prototype class entry for this year’s Rolex 24 Hours, the opening round of the 2018 IMSA WeatherTech Championship season. If you missed my preview of the first half of the class, you can find it here Part 1.

#37 Jackie Chan DC Racing Jota Oreca-Gibson: Robin Frijns/Dani Juncadella/Felix Rosenqvist/Lance Stroll

Jackie Chan DC Racing have been very competitive in the WEC last season, and now make the trip Stateside for the Rolex 24. The team have mastered the LMP2 class in the WEC, but now come up against the favoured Daytona Prototypes for the first time. The LMP2 cars struggled last year to match the DPI entries on overall pace, something the series was keen to rectify for this season.

On the driving front the team arrive with a very strong line-up. Williams F1 racer Lance Stroll returns to the race after an up-and down rookie season in F1. Partnering him is Blancpain GT champion Robin Frijns, Former FIA European F3 champion Dani Juncadella and Swedish jack of all trades Felix Rosenqvist. Whilst this line-up does not possess much prototype experience, all four are seriously quick drivers who are contenders for the most formidable line-up on the grid. Stroll set the cars fastest time at the test, but was a massive 1.7 seconds down on the overall pace. The team will need to close this gap if they want a shot at victory in such a competitive entry.

#38 Performance Tech Oreca-Gibson: James French/Kyle Masson/Pato O’Ward/Joel Miller

Performance Tech were the IMSA PC class champions in the final year of the class in 2017, and have now stepped up to the prototype ranks with a new Oreca-Gibson. The team were dominant last year but will face a much tougher test this year in such a strong and competitive field.

The team have retained both James French and Kyle Masson from last year, with both impressing with their overall speed. Pato O’Ward joins them for the endurance rounds and the young Indy Lights racer is very quick.  Youth is the theme with this line-up, as all three are all under 26 and despite having an all silver line-up they could spring a surprise come the end of the race. Former Mazda factory driver Joel Miller was a late addition to the team, and provides added experience to a very promising line-up.

#52 AFS/PR1 Mathiasen Ligier-Gibson: Sebastien Saavedra/Gustavo Yacaman/Roberto Gonzalez/Nic Boulle

This #52 AFS/PR1 entry will be the most recognisable on track thanks to it fluorescent red and yellow livery, in the debut race for this team with former PC front runners PR1 Mathiasen motorsport joining forces with Indy Lights team AFS racing. The PR1 crew found the step up to the prototype class last year tough initially, although showed flashes of potential on which we should see more regularly this season.

The team have signed promising young Indycar racer Sebastien Saavedra and fellow Colombian Gustavo Yacaman for the full season. Yacaman is an experience prototype racer who is joined by Nic Boulle and Rodolfo Gonzalez. Boulle drove for the team last year and brings some experience to line-up, with Gonzalez a quick and underrated driver who gets a big chance to impress with this drive. The team struggled for ultimate pace in the Roar test, finishing 19th overall with a quickest lap two seconds off the top end pace. The team may struggle to match the front running entries, but they could spring a surprise if they get some luck along the way.

#54 CORE Autosport Oreca-Gibson: Jon Bennett/Colin Braun/Romain Dumas/Loic Duval

CORE Autosport make their debut in the prototype class after a year racing a GTD Porsche. The former dominant PC class champions have made the jump with a Oreca-Gibson package, which has proved the dominant of the LMP2 chassis across the globe. The LMP2 spec cars appear to have a slight deficiency in overall space compared to the DPI entries, but anything can and most likely will happen at the Rolex 24.

The long-term driving duo of Jon Bennett and Colin Braun stay on for another year, with the pair working very well together. Joining them for this race are two stud racers in factory Porsche and Audi drivers Romain Dumas and Loic Duval. Both are very quick drivers who will fly at the wheel of the car. In the pre-race test Braun took the plaudits for setting the cars quickest time, quick enough for tenth overall. Whilst the team may struggle to match the ultimate pace with gentlemen driver Bennett in the team, they will likely surprise many with how strong they are in their debut prototype race.

#55 Mazda Team Joest Riley-Mazda: Jonathan Bomarito/Harry Tincknell/Spencer Pigot

Along with Penske and Acura, the improving quality of the IMSA series is shown with this factory Mazda entry. After parting ways with long-term partners SpeedSource the Japanese manufacturer joined forced with former Audi factory team partners Team Joest. After an intensive test programme over the second half of last year the team will be as prepared as they can be going into the Rolex 24.

At the test it was Brit Harry Tincknell who set the cars quickest lap, 1.4 seconds off the fastest overall lap. Tincknell is the new signing for this #55 entry, and has plenty of success including a LMP2 class win at the Le Mans 24 Hours on his debut. Joining him for the season is Jonathan Bomarito, whose experience and pace is being carried over from the old regime. Completing the trio for Daytona is Indycar racer Spencer Pigot, who drove for the team in this race last year. In such a competitive field the team may struggle to trouble the podium unless they can improve their overall speed quickly.

imsa-daytona-january-testing-2018-55-mazda-team-joest-mazda-dpi-p-jonathan-bomarito-spence

#77 Mazda Team Joest Riley-Mazda: Oliver Jarvis/Tristan Nunez/Rene Rast

The second factory Mazda Joest entry is this #77 car, another that will have been bolstered by both updates to its Riley chassis and the input of the highly successful Joest team. The team bring with them a winning mentality from their highly successful sting masterminding 13 Le Mans 24 Hours victories for Audi, and have now turned their attention to the Mazda DPI programme.

The team have switched things slightly for this year on the driving front, drafting in former Audi factory driver Oliver Jarvis for the full season to partner the young American racer Tristan Nunez, who has been nurtured and developed over several years at this level by Mazda. Completing the line-up for the endurance rounds is current DTM champion Rene Rast, who is a very quick sportscar driver who finished third overall last year in an unfancied VisitFlorida.com racing Riley. Much like their sister entry the overall pace is unknown from this Mazda package, therefore it’s hard to predict what this factory outfit can do in the race. They may need some luck to challenge at the sharp end, but discount them at your peril.

#78 Jackie Chan DC Racing Jota Oreca-Gibson: Alex Brundle/Antonio Felix da Costa/Ho-Pin Tung/Ferdinand Habsburg

Jackie Chan DC Racing have proved to be class leaders in the WEC and Asian Le Mans Series, so have now set their sights on cracking America. The team have brought two entries for this Rolex 24, but will face stiff competition from not just the LMP2 field but the DPI entries also. The team enjoyed a good pre-race test at Daytona, gaining valuable data and Alex Brundle showed the cars potential with the ninth fastest lap.

Brundle has been a mainstay of LMP2 racing and massively impressed with the team last year. Joining him for the race is another regular driver in Chinese talent Ho-Ping Tung, a front runner in the teams ALMS entries. New to the team are two very talented young racers in Antonio Felix da Costa and Ferdinand Habsburg. Felix da Costa is a quick single seater convert who has been picked up by BMW as a factory driver and Habsburg came of age with a very impressive display at the Macau Grand Prix last year. The teams lack of experience in this series may hamper them in the race, but the team have brought a very high-quality line-up and add an extra element of competitiveness to this prototype entry.

#85 JDC-Miller Oreca-Gibson: Robert Alon/Simon Trummer/Austin Cindric/Devlin DeFrancesco

The #85, affectionately dubbed the yellow boat, returns for another year at this level after a very impressive debut campaign last year. The team stick with their trusted Oreca-Gibson package, although have made some slight changes on the driving front for this year.

The team have retained Robert Alon after his impressive displays last year, but with the team expanding to two entries this year he’s been split up from his team mates of last year. Partnering him is former GP2 front runner Simon Trummer. He is a very quick young driver who makes the switch across to sportscar racing. He immediately set the cars fastest lap at the test, 1.5 seconds down on the #31 Whelen entry. Completing the line-up is talented young Nascar racer Austin Cindric and FIA European F3 racer Devlin DeFrancesco. The team are prime candidates for a giant-killing act this year, so keep an eye on their progress in the race.

#90 Spirit of Daytona Dallara-Cadillac DPI: Matt McMurry/Tristan Vautier/Eddie Cheever III

Long term IMSA entrants Spirit of Daytona are much changed this year, after a difficult 2017 season for the Daytona based team. The team ditched their Riley LMP2 chassis halfway through last year, and have now switched to the dominant Cadillac DPI package. The team have also lost title sponsor VisitFlorida.com so return this year under the Spirit of Daytona banner.

On the driving front it’s also all change for the team, with 2017 drivers Marc Goossens and Renger van der Zande replaced by Tristan Vautier and Matt McMurry. Vautier moves across from Blancpain GT in Europe and has plenty of American racing experience. He is joined by young American Matt McMurry in what is a very strong line-up for this team. A late addition to the team is young racer Eddie Cheever III. He impressed at the Roar test with the second fastest lap time, just 0.2 seconds off top spot. The team took third last year in an uncompetitive package so with the Cadillac DPI package the team have all the necessary ingredients for success this year.

imsa-daytona-january-testing-2018-90-spirit-of-daytona-racing-cadillac-dpi-tristan-vautier

#99 Gainsco JDC-Miller Oreca-Gibson: Stephen Simpson/Chris Miller/Misha Goikhberg/Gustavo Menezes

A fans favourite returns in 2018, with the iconic red Gainsco red dragon appearing with this expanded JDC-Miller team. The most surprising team of last year have expanded to two entries this year, and will look to build on a very good year for the team in 2017.

The team have retained their drivers from last year, namely Stephen Simpson, Misha Goikhberg and Chris Miller. All three-impressed many with their consistently fast driving last year although Simpson is the stand-out in this entry. He set the fastest lap at the test and has consistently been a tenth or two ahead of the rest in this car. Completing the driving talent is young WEC LMP2 racer Gustavo Menezes, and the addition of such a highly regarded and very quick prototype racer only enhances their chances of a good result. If the team can run cleanly expect a surprise from this team.

2018 Rolex 24 Prototype Preview Part 1

The IMSA WeatherTech Championship fires back into life in 2018 with its longest race kicking off the season. The Rolex 24 is an event that has been growing in stature every year since the American sportscar community merged in 2014. This year the race is set to yet another classic, with arguably its strongest ever field competing tooth and nail for victory.

The race is usually decided by a matter of seconds, and this year twenty high-quality prototype entries will be fighting it out for the victory. There are some off-season driver changes from the top returning teams and some very strong new entries along with a host of top international teams and driving talent descending on Daytona International Speedway this week. Let’s take a look at the prototype entry first.

#2 Tequila Patron ESM Ligier-Nissan DPI: Ryan Dalziel/Olivier Pla/Scott Sharp

Extreme Speed Motorsport return to IMSA competition this year with another two-car entry. This #2 entry of Ryan Dalziel and Scott Sharp is returning from last year, but they have a new partner for their Tequila Patron North American Endurance Cup events. Frenchman Olivier Pla is world renowned for being seriously quick in Ligier LMP2 entries, and it was him that set the quickest time for the team at the pre-race Roar Before the 24 tests, although it was still 1.7 seconds off the ultimate pace of the Cadillac’s.

The team appeared to focus on endurance runs throughout the test, with their fastest lap only good enough for 15th overall. All three have plenty of experience of the IMSA series, although the Nissan Ligier DPI will need to be at its best to match the seemingly dominant Cadillac DPI entries. It will be interesting to see if the team can improve their ultimate pace during the race week, with rumours of some team’s sand bagging at the Roar.

imsa-daytona-january-testing-2018-2-tequila-patron-esm-nissan-dpi-scott-sharp-ryan-dalziel

#5 Mustang Sampling Action Express Dallara-Cadillac DPI: Filipe Albuquerque/Joao Barbosa/Christian Fittipaldi

This #5 Mustang Sampling Action Express entry has proved one of the leading entries in IMSA competition for the past several seasons. They were usurped by Wayne Taylor racing last season, but look to reclaim their crown this year.

On the driving front the team have made a minor change with the Portuguese Audi factory driver Filipe Albuquerque replacing long-term driver Christian Fittipaldi for the full season. Fittipaldi has scaled himself back to NAEC entries only, so for the Rolex 24 at least nothing has changed.

Albuquerque set the cars fastest lap at the test, a 1.36.135, which put him third overall. Since the new rules came into effect last season the Dallara-Cadillac DPI entries have dominated the series, and based on the Roar this doesn’t look likely to change. If the other teams cannot make improvements expect this #5 entry to be fighting it out for the victory amongst the other Cadillac DPI entries, despite attempts from IMSA to peg back the dominant Cadillac’s.

imsa-daytona-january-testing-2018-5-action-express-racing-cadillac-dpi-joao-barbosa-christ

#6 Acura Team Penske Oreca-Acura DPI: Dane Cameron/Juan-Pablo Montoya/Simon Pagenaud

Team Penske are a giant of American motor racing, and this season have branched out into the IMSA WeatherTech series with a factory Acura DPI programme. The arrival of Penske and Acura is a real coup for the series and has drawn plenty of attention to the Rolex 24.

The team have enjoyed a good winter testing programme, but a 24-hour race for a debut is going to be very difficult. On the driving front the team have lured Dane Cameron away from Action Express, after he shone in the #31 Whelen entry last year. Partnering him for the year is the well-known Juan-Pablo Montoya, who returns to full time racing after losing his Indycar seat last year. Current Penske Indycar racer Simon Pagenaud is the team’s endurance rounds driver and this is a formidable driving trio. A debut victory may be very tough to achieve with a new car that was 1.1s off the fastest laps at the test, but if any team can do it’s Penske.

imsa-daytona-january-testing-2018-6-acura-team-penske-acura-dpi-dane-cameron-juan-pablo-mo

#7 Acura Team Penske Oreca-Acura: Helio Castroneves/Ricky Taylor/Graham Rahal

The other Team Penske entry is this #7 car, with both cars proving tough opponents for their rivals. All three drivers in this car completed over 50 laps across the three days of pre-race testing, with Ricky Taylor setting the cars fastest time, although it proved 0.3s off his team mates fastest lap and 1.4 seconds off the pace of the Cadillac DPI entries.

On the driving front the team recruited 2016 champion and undisputed qualifying king Ricky Taylor away from his family Wayne Taylor racing team, to partner Helio Castroneves for the season. Castroneves has called time on a long and decorated Indycar career and although he was in the bottom half of fastest times at the test, expect him to make major improvements every time he gets in the car. Joining the duo for the endurance rounds is fellow Indycar racer Graham Rahal, who completes another top-quality entry in this stacked prototype field.

#10 Konica Minolta Wayne Taylor Racing Dallara-Cadillac DPI: Ryan Hunter-Reay/Jordan Taylor/Renger Van der Zande

The Wayne Taylor racing crew return this year as defending champions after a dominant championship year in 2017. The team won the first five races so return as defending Rolex 24 winners, although this year has seen some changes on the driver front for the team.

Wayne Taylor’s two sons Jordan and Ricky were a dynamic duo for several seasons but have now been split up with elder brother Ricky defecting to the new factory Acura Team Penske entry.  Younger brother Jordan is now partnered for the year by the very quick Dutch driver Renger van der Zande. He set the cars fastest time at the test with a 1.36.481, 0.6 of a second off the fastest lap. Completing the line-up is Indycar racer Ryan Hunter-Reay, who has plenty of Rolex 24 experience with this likely being his best chance of victory. All three drivers set fastest laps within the top seven, which shows that this WTR Cadillac DPI entry once again looks very strong contenders for victory.

#20 BAR1 Motorsport Riley Mk30-Gibson: Marc Drumwright/Eric Lux/Alex Popow/Tomy Drissi/Brendan Gaughan

Former PC team BAR1 Motorsport have made the step up to the prototype ranks, with the only Riley chassis in the field. The team acquired the ex–Keating Motorsport car and with new evo updates to the car it will be an improvement from a difficult debut season last year.

The team have finalised their driver line-up at the last minute, signing experienced PC runner Marc Drumwright, former PC class champion and PWC front runner Eric Lux, former Rolex 24 front runner Alex Popow, Trans-Am racer  Tomy Drissi and Nascar racer Brendan Gaughan. All five have plenty of experience however the team may struggle to match the ultimate pace with a silver and bronze rated driver crew. Compared to the platinum and gold crews in this class a good result for the team would be a clean run and a top eight finish in class.

imsa-daytona-january-testing-2018-20-bar1-motorsports-multimatic-riley-lmp2-joel-miller-ry

#22 Tequila Patron ESM Ligier-Nissan DPI: Pipo Derani/Johannes van Overbeek/Nicolas Lapierre

This #22 entry is the second Extreme Speed motorsport car entered, and just like their #2 entry has a strong chance of victory this year. The team have proved themselves in IMSA and were winners of the Rolex 24 only two years ago. The team have maximised their Nissan DPI package although they struggled for ultimate pace at the Roar test.

On the driving front the team have a full season pairing of Pipo Derani and Johannes van Overbeek. Derani is returning to the team where he made his name two years ago thanks to blistering pace and van Overbeek brings a wealth of experience to the team. They are joined this year by Frenchman Nicolas Lapierre, a very distinguished prototype racer who has previous experience at the Rolex 24. The team are the most likely team to challenge the Cadillac DPI teams dominance, but may need a pinch of luck along the way if they want overall victory.

#23 United Autosport Ligier-Gibson: Fernando Alonso/Phil Hanson/Lando Norris

United Autosport go into this race with the highest amount of press attention surrounding them, thanks to the presence of double F1 world champion Fernando Alonso. The Zak Brown affiliated team have used his connections to entice McLaren racer Alonso to the team for his sportscar debut, in likely preparation for a crack at Le Mans 24 Hours victory in the coming years.

United Autosport were front runners in the European Le Mans Series last season, and are amongst an influx of very impressive international one-off entries for this race. Partnering Alonso is young sportscar talent Phil Hanson and single seater racer Lando Norris. Hanson has impressed with the team in the ELMS last year, and Norris claimed the FIA European F3 Championship at his first attempt. Although this is an inexperienced line-up they have enough quality to pressure the Cadillac DPI entries, although they may struggle for ultimate pace with their LMP2 spec Ligier-Gibson.

#31 Whelen Engineering Action Express Dallara-Cadillac: Felipe Nasr/Eric Curran/Mike Conway/Stuart Middleton

This #31 entry is the Whelen backed Action Express entry, and may prove a surprise winner at the Rolex 24. Despite an off-season that has seen some driver changes this crew aced the pre-race Roar test, setting the fastest overall lap and unofficial lap record with a 1.35.806 from Felipe Nasr.

Nasr replaces the departing Dane Cameron in this #31 entry, partnering Eric Curran. The team have also signed Mike Conway and Stuart Middleton to bolster their driver line-up. Nasr is a former F1 racer with Sauber and along with Toyota LMP1 driver Conway they will be the quickest two drivers in this car. Curran brings a wealth of experience and Middleton is the winner of the Whelen Sunoco challenge, which grants the most successful British club racer with this coveted Rolex 24 seat. Whilst Curran and Middleton may lack the last tenth of pace compared with Nasr and Conway with such a strong package this team can absolutely win this race.

#32 United Autosport Ligier-Gibson: Will Owen/Paul Di Resta/Bruno Senna/Hugo de Sadeleer

This #32 entry may not have the ultimate star power of its sister #23 entry, but the second United Autosport car is another promising one-off entry for the race. The team will be learning the nuances of IMSA racing with every session they complete, and they are a threat to the established order on track.

The team have brought in two high-profile racers in former F1 drivers Paul Di Resta and Bruno Senna. Di Resta is making his sportscar debut but has the talent to adapt well in the car, with Senna being the current LMP2 WEC champion. He set the cars fastest lap at the test, and was just under a second quicker than his team mates. Will Owen and Hugo de Sadeleer are two young drivers who were very impressive in the European Le Mans series last season. The team lacks in overall IMSA experience but have enough talent to have other teams worried going into the race.
