The 2017 international motorsport season begins in earnest with the 55th running of the Rolex 24 Hours from the Daytona International Speedway. This years running marks a new era for the IMSA WeatherTech Sportscar championship, with wide scale changes to the premier prototype division thanks to a new combined rulebook aligning the previous LMP2 and Daytona Prototype cars.

With the new DPI regulations they should ensure greater equality between the previous LMP2 and Daytona Prototype entries. Whilst there will be inevitable balance of performance issues to iron out in the build up to the race, one thing that can be guaranteed is the overall quality and competitiveness in the prototype category. Every car in the premier class has a chance of victory, should they have a good run and be blessed with that all important luck needed to win such a prestigious 24 hour race.

Last years victors Extreme Speed Motorsport return to the IMSA series full time this year after two years in the World Endurance Championship, but they will have plenty of competition for the victory once again this time out. Let’s take a look at the entries and assess their chances of victory.

#2 Tequila Patron Extreme Speed Motorsport Ligier-Nissan DPI: Ryan Dalziel/Scott Sharp/Pipo Derani

Tequila Patron and the Extreme Speed team have returned stateside after a mixed two years in the WEC, and despite a new range of prototype entries expect them to pick up exactly where they left off in this series. This is the crew that came out victorious in last years Rolex 24, therefore the target will be on their back all weekend as they aim to do something very difficult and retain their trophies from a year ago.

Despite being the reigning champions a lot has changed for this crew from last year. Most notably is the new Ligier-Nissan DPI package that they have chosen to use. With such a new set of regulations its currently unclear which package will prove most suitable for the Daytona track, with the Roar not giving away too much as teams don’t want to show their hands too early.

On the driving front the team also has some changes, with the team switching across Ryan Dalziel and Johannes Van Overbeek for this year. With the talented Scot Dalziel now partnering Sharp and Pipo Derani this team has a great mix of speed and experience in this lineup.  Derani in particular stole the show last year with his consistently fast driving, and if he can repeat those feats this year, backed up by Sharp and Dalziel this team has every chance of victory if their new DPI package can stay reliable.

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

The Action Express team have established themselves as one of the premier prototype teams in the IMSA series over the past three to four year, largely based on the results of this number five entry.  With back to back titles in 2014 and 2015, this entry was beaten only by its teammates in last years championship.

The team always run strongly at Daytona and last year once again challenged for the overall victory until the final hours. They have remained with General Motors, although this years new DPI is badged as a Cadillac rather than a Chevrolet. Aside from the new DPI car the team have stuck with a driver line up that has produced major success for them.

Both Joao Barbosa and Christian Fittipaldi are hugely experienced whilst retaining their speed, something Audi factory driver Filipe Albuquerque does not lack. He showed well with the team last year and this year will be hoping they can remain in the lead fight right up until the chequered flag. Along with the #2 Extreme Speed motorsport entry this is one of half a dozen cars who have a very good chance of victory. Expect to see this car at the front for large portions in the race if they can run cleanly.

#10 Konica Minolta Dallara Cadillac DPI: Jordan Taylor/Ricky Taylor/Max Angelelli/Jeff Gordon

The battles between the Action Express and Wayne Taylor racing teams have gone down in this championships short history, with the two of them separating themselves from the rest of the full season entries in the past three years. This year their battle for victory will be renewed beginning with the Rolex 24, a race that has not been kind to this team in recent years.

The team have always found trouble late on when in contention for victory, something the team will be hoping a new set of regulations may help with. They have decided to also stick with what they know and the GM brand, and have retained three quarters of their driver line up from a year ago.

Owner Wayne Taylor’s sons Jordan and Ricky return and will be right on the pace all weekend, ably supported by the vastly experienced Max Angelelli in his final race before retirement. Angelelli has been a huge asset to this team since his days partnering Wayne and will be hoping he can end his career on a high note. For their final driver the team have caused a stir by signing retired Nascar legend Jeff Gordon. Whilst he has limited Sportscar experience, he has plenty of pace and is a good addition to this already formidable lineup. This is another entry to look out for throughout the 24 hours.

#13 Rebellion Oreca 07-Gibson:  Sebastien Buemi/Nick Heidfeld/Neel Jani/Stephane Sarrazin

The Rebellion team embark on their first season in the LMP2 category after being mainstays of the LMP1 privateer class. Along with their WEC programme is a crack at the Tequila Patron North American Endurance Cup, consisting of the premier races on the IMSA calendar.

With a stable Oreca-Gibson chassis/engine combination the highly experienced team have put together an all star line-up for the Rolex 24. LMP1 factory drivers Sebastien Buemi, Stephane Sarrazin (Toyota) and current WEC champion and Le Mans 24 Hours winner Neel Jani (Porsche) are joined by regular driver and ex-F1 mainstay Nick Heidfeld.

The team having previous experience from their 2013 successful foray into the American Sportscar scene, are will be looking for a debut victory this time out. If the team can have a clean run, this entry is a very serious contender for the overall win. With such a competitive class and the 24 hour race duration anything can happen, although if I was forced into choosing a pre-race favourite, I would likely back this Rebellion racing entry.

#22 Tequila Patron Extreme Speed Motorsport Ligier-Nissan DPI: Ed Brown/Johannes Van Overbeek/Bruno Senna/Brendon Hartley 

The other Extreme Speed motorsport entry is not going to play second fiddle to the teams other car. This entry still has a very good chance of victory, given the professionalism and quality of this team, along with a great driver line up.

Porsche LMP1 factory driver and former WEC champion Brendon Hartley is an excellent signing for this team, one of the genuinely fastest guys on the sportscar scene at the moment. Former F1 driver Bruno Senna has also joined this lineup, showing his talents with a excellent adaption to prototype racing in the LMP2 class of the WEC last season.

Full season drivers Johannes Van Overbeek and Tequila Patron CEO Ed Brown complete the lineup. Van Overbeek has a wealth of experience and speed, forming an excellent working relationship with long term co-driver Brown. The only slight question mark surrounding this entry may be Brown.

He is one of the few true amateur drivers in the class, and whilst he has excelled and improved rapidly in sportscar racing, he may struggle to match the consistent ultimate pace of the world class professional drivers he will be competing with. Do not count this entry out as you may regret it, although they may need a little extra help if they want to be wheeled into victory lane come Sunday afternoon.

#31 Whelen Engineering Action Express Racing Dallara Cadillac DPI: Dane Cameron/Eric Curran/Mike Conway/Seb Morris

The defending WeatherTech IMSA champions return for a crack at the Rolex 24. the jewel in the IMSA season crown. This entry stepped out of the shadows of their illustrious team mates last season to win the title, and will be hoping they can repeat this result this season, despite the major changes in the prototype class.

It’s unclear as to the ultimate pace of the new Cadillac DPI entries, having not topped the times at the pre-race Roar before the 24 test several weeks ago. Were they sandbagging, or are they genuinely short on pace compared to their rivals? Only the teams themselves know.

On the driving front the full season lineup of the very fast Dane Cameron and Eric Curran are joined by Brits Mike Conway and Seb Morris. Conway is a Toyota factory prototype driver and is an excellent signing for this team. Morris is a slightly different story, having won the Sunoco challenge, which rewards the best overall driver in British national racing with a drive in the Rolex 24. Such alumni of this prize include F1 driver Felipe Nasr, so do not discount Morris. He was a very quick single seater driver before switching his attention to GT racing, having shown similar pace in British GT last year.

With Conway leading the lineup this entry may lack that blistering ultimate pace of their rivals over the course of a stint, but do not think they are simply here to make up the numbers. They are the reigning champions and that alone will mean no other team counts them out.

#52 PR1/Mathiasen Motorsport Ligier JSP2-Gibson: Tom Kimber-Smith/Jose Gutierrez/Mike Guasch/RC Enerson 

The PR1/Mathiasen have been front runners in the prototype challenge class for the past several years in the IMSA series, tasting some success with class victory in the 2015 Rolex 24. With the widespread change in the prototype class regulations, the team have made the step up for this season.

Given pre-season testing choosing the Ligier JSP2 package seems a smart move at this moment, and the team have stuck with a lot of their PC class drivers. With familiarity and experience needed with the move up this is a smart move by the team. The vastly experienced Tom Kimber-Smith will likely lead this team, having plentiful experience at this level from the past few years.

Jose Gutierrez showed himself well last season in his sportscar debut, having made the jump across from the Pro Mazda single seater series. Although he didn’t complete the entire season, a year of adapting to the series will put him in good stead for this season. Mike Guasch is a quick amateur driver for this team, and has spent a large portion of his recent career with the team. After winning the LMP3 class in the European Le Mans Series, he will be hoping his good form can continue into 2017.

Completing the lineup is the young American single seater racer RC Enerson, who makes his sportscar debut this weekend. He has progressed up the Mazda Road to Indy ladder right up to Indycar last season, although his lack of experience will sportscar may hamper him during the week. He is tremendously fast and once he adapts to the car and the level of traffic, expect him to flash some seriously fast times during the race.

#55 SpeedSource Riley Mazda DPI: Jonathan Bomarito/Tristan Nunez/Spencer Pigot 

The works backed SpeedSource Mazda team return to the IMSA series in 2017 having shown promise throughout the 2016 season. With a new Mazda badged Riley DPI, which in my opinion is the best looking car in this class, will be hoping they can finally deliver on their long running promise.

The team is highly talented and this extends to the driver line up. Former single seater convert Jonathan Bomarito has now added experience to his speed and is well versed with the team having spent the past few years with them. He will provide the most experience, although both young team mates Tristan Nunez and Spencer Pigot have also raced this entry last year.

Nunez has adapted well having progressed through the Cooper Tyres IMSA lights series, having been nurtured by this team he gets better with every passing season and is now established as a prominent IMSA sportscar driver, despite being only 21. Pigot is a single seater who flashed promise in Indycar last season, and returns to Daytona looking to improve upon last years frustrating race where mechanical issues forced them out. If the Mazda DPI proves quick expect this team to be taking full advantage of it, and maybe they can achieve a rare and long overdue podium come Sunday afternoon.

#70 SpeedSource Riley Mazda DPI: Tom Long/Joel Miller/James Hinchcliffe

The other Mazda factory entry is this #70 car, both of which have shown well at the pre-race Roar before the 24. Whilst it was the #55 car that set the headline times at the test, this entry has just as much a chance of victory or class podium. The SpeedSource team are highly professional and have plenty of experience in this race, plus the might of Mazda North America supporting their efforts.

The team remains largely unchanged on the driving front, with long time Mazda drivers Tom Long and Joel Miller providing a wealth of experience for this entry. Both are also capable of produce a very fast average pace across a stint, especially former single seater convert Miller. Completing the trio is Indycar star James Hinchcliffe, who reunites with the SpeedSource team for Daytona after taking last year out. He will be the star turn and if he can adapt to the new Mazda DPI car quickly, he will likely be the one setting the cars fastest times. So much in unknown going into this race, but if the testing pace proves to be an accurate reflection of outright speed, expect this car to be on the podium if it can keep clean and reliable.

#81 DragonSpeed Oreca 07-Gibson: Loic Duval/Ben Hanley/Henrik Hedman/Nicolas Lapierre

The very young DragonSpeed racing team make their Rolex 24 debut with one goal in mind this weekend, to claim overall victory in this prestigious race. The team are racing their Oreca 05 from last season, updated to new 07 spec, and have impressed so far.

The team debuted at the Sebring 12 hours last season and again have returned stateside before taking on the European Le Mans Series this year. What the team lack in sportscar experience they more than make up for with their driver line up. Amateur Swedish racer Henrik Hedman has plenty of sportscar experience however he will likely to struggle to match the pace of the professional drivers simply because he is an amateur doing this for fun, do not think that will mean he is slow and he will be a very good and consistent driver for the team.

Joining him is Brit former single seater Ben Hanley, who like a shooting star rose to prominence very quickly before seemingly disappearing just as quickly. He is still a very quick racing driver who seems to have finally found a home with this DragonSpeed team. Completing the lineup are sportscar royalty, Audi factory driver Loic Duval and LMP2 WEC champion Nicolas Lapierre. Both have plenty of top line sportscar experience and will provide blistering pace for this car when they are at the wheel.

Having topped the pre-race test this team are looking good if they can keep this pace up consistently across the week culminating in the race. If they can be reliable this team has every chance of a class podium, despite the seeming disadvantage of an amateur driver, such is the overall quality of the team and the rest of the lineup.

#85 JDC/Miller Motorsport Oreca 07-Gibson: Mikhail Goikhberg/Stephen Simpson/Chris Miller/Mathias Beche 

The second team to step up from the Prototype Challenge class is this JDC/Miller motorsport entry, and they will have fond memories of this race from last year. They survived a race of attrition in this class to secure an unexpected victory, something that carried across to the rest of the season as they finished third in class.

The team have chosen the Oreca 07-Gibson as their weapon of choice, with the DragonSpeed team showing the potential of the car in the re-race test. If this team can get to grips with the car and extract similar pace they will definitely be contenders for yet another upset victory this year.

The team has gone with familiarity for this year, having retained Stephen Simpson and Mikhail Goikhberg for this year. Both excelled last year and a resurgent Simpson reminded people why he was a formerly highly rated A1GP and Indy Lights driver. He has not lost any of his previous pace, he has simply now added experience to his sportscar armory. Goikhberg adapted well after winning the 2014 Mazda Prototype Lights series, he has found a home with the JDC/Miller team and rewarded them with an excellent season last year.

Chris Miller also returns this year after partial IMSA seasons with the team over the past several years. He has struggled with attaining a full season drive for several years now, which only makes his performances for this team even more impressive, considering his lack of experience. He is an underrated driver deserving of a full season IMSA drive, and so far he will be joining the team for the four Tequila Patron North American Endurance Cup events. Completing the lineup is Swiss racer Mathias Beche, a driver who has firmly established himself as a promising sportscar talent. He has impressed in recent years with the Thiriet by TDS and Rebellion racing teams, and is currently being rumoured to be joining the Toyota factory LMP1 programme this year. He will be hotshoe in this car and will lead the team as far as they can go in this race.

#90 VisitFlorida.com Spirit of Daytona Riley Mk30-Gibson: Renger Van Der Zande/Marc Goossens/Rene Rast

Long time IMSA entrants VisitFlorida.com racing return having gone a slightly different route to their traditional rivals. Whilst the likes of Action Express and Wayne Taylor racing have gone with the DPI route, this team have instead gone for a more European twist with their new LMP2 spec Riley Mk30. The team have made no secret of their desire to race at the Le Mans 24 Hours in the coming years, with their’s the only traditional Riley on the grid this year.

After an overhaul with their previous driver line up this year seems more stability, with the vastly experienced and very quick Belgian Marc Goossens remaining with the team for this year. He will have a new team mate in Dutchman Renger van der Zande, with Ryan Dalziel returning to the Tequila Patron ESM team. Van der Zande has long been one of the fastest drivers in the PC class, and is long overdue this promotion to the Prototype class.

This lineup is completed with Audi factory driver Rene Rast, someone who has solidified his success at this race in the GTD class in years prior. With plenty of Audi LMP1 experience he should find the adjustment to the Riley relatively easy, and he will be very fast throughout the week no doubt. This locally based team have never had much luck in this race, and could a new car bring a change in their fortunes? Based on testing times they may struggle, but many expect the order to have significantly change come the race.

That wraps up my preview of the Prototype class for this years 2017 Rolex 24. The class seems rejuvenated this year with plenty of intrigue as genuinely you could not call a winner for this race. I will be one of the many sportscar eagerly glued to the race this weekend, excited to see the outcome.
