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 15^th 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.

#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.

#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.

#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.

#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.
