The new decade brings the same ultra competitive IMSA WeatherTech series. The centre-piece Rolex 24 will be the first major sportscar race of the decade, and always attracts the best teams and drivers from around the globe. To win the famous Rolex watch can launch careers, and this year is set to yet another 24 hour sprint race.

The DPI class returns with eight entries, down slightly from eleven last year. Despite the drop in numbers, the outstanding quality remains. Wayne Taylor Racing return to defend their crown with a much changed line-up, with Acura duo Dane Cameron and Juan Pablo Montoya also back after claiming the title last year. Let’s take a look at the eight DPI entries.

#5 JDC-Mustang Sampling Racing Cadillac DPI-V.R: Joao Barbosa/Sebastien Bourdais/Loic Duval

JDC Miller have partnered with Mustang Sampling for their strongest IMSA line-up to date. Mustang Sampling took multiple titles and Rolex 24 wins during their almost decade long stint with Action Express.

Barbosa jumps across from Action Express, joining Indycar refugee Sebastien Bourdais. Bourdais was cruelly dropped from his Indycar drive, and will no doubt show that decision to be a mistake in IMSA. Le Mans 24 Hours winner Loic Duval warms up for his Audi DTM commitments with a Rolex 24 drive.

The team were consistent at the Roar test,completing over 150 laps during the three day test. The team never troubled the top of the times, and were a lowly seventh in the DPI pit box qualifying session. At this level the team will need both speed and reliability to trouble the podium.

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

Acura realised their potential last year, winning the title with this #6 crew in their second year in IMSA. Dane Cameron and Juan Pablo Montoya were faultless all year, and thoroughly deserving champions with three wins. They return aiming to start their title defense strong with a Rolex 24 win.

Last year the Acura struggled with the unique demands of Daytona, struggling for top speed on the banking sections, yet the pre-race BOP adjustments weren’t kind to Acura. Indy 500 winner Simon Pagenaud completes a very strong driver line-up. Despite lacking top speed you can never discount Team Penske.

Juan Pablo Montoya noted that Acura struggled for outright pace at the Roar, however they did show promise with their Sunday running. Third in the qualifying session shows the team has improved compared to last year.

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

The #7 crew were overshadowed last year by their title winning team mates, something they will no doubt want to rectify. It’s the third year of this Acura Team Penske program, and they have yet to win the Rolex 24.

Helio Castroneves and Ricky Taylor are joined by former Indy 500 champion Alex Rossi. He has experience of the Acura from last year, and this is yet another formidable line-up in this class.

They showed good one lap pace on Sunday at the Roar, topping a Sunday session and pipped their team mates for second in the qualifying session. To pick one Acura over the other is impossible, both are very strong contenders.

#10 Konica Minolta Wayne Taylor Racing Cadillac DPI-V.R: Ryan Briscoe/Scott Dixon/Kamui Kobayashi/Renger van der Zande 

The 2019 Rolex 24 victors return, but are much changed. Gone is son of team owner Wayne Taylor Jordan Taylor, and superstar Fernando Alonso is also missing. In their place are two refugees from the Ford GT GTLM program, Ryan Briscoe and Scott Dixon.

Dixon is a legend of Indycar racing, and the five-time champion also has a rich history at the Rolex 24. Ryan Briscoe replaces Taylor as the team mate to Van der Zande. Toyota WEC racer Kamui Kobayashi returns after a successful cameo last year.

The Sunday running encapsulated their test. They finished bottom of the qualifying session to decide pit boxes, but then topped the final Sunday afternoon session. The team has a wealth of experience, so counting them out would be stupid. The team need Dixon and Briscoe to get up to speed with the Cadillac quickly.

#31 Whelen Engineering Action Express Cadillac DPI-V.R: Pipo Derani/Felipe Nasr/Filipe Albuquerque/Mike Conway

Action Express have scaled back from two to one car this year, but what a team they have assembled. The team is well proven and hugely successful in IMSA, something they hope to carry over from 2019. Pipo Derani and Felipe Nasr are arguably the strongest driver line-up, and are joined by Toyota WEC ace Mike Conway, along with former Audi WEC racer and Rolex 24 winner Filipe Albuquerque.

The team just missed out on the IMSA title last year, and have finished no lower than second in the past three Rolex 24’s. The team were the strongest Cadillac runner at the Roar, so fourth in the qualifying session will be a slight disappointment. Cadillac has dominated the Rolex 24 in recent years, so to be the quickest Cadillac runner is a very good sign.

#55 Mazda Team Joest Mazda RT24-P: Jonathan Bomarito/Ryan Hunter-Reay/Harry Tincknell

Mazda finally delivered in 2019 after showing frequent flashes previously. Winning three races was a massive step for the Mazda Team Joest crew, but now they want victory in the marquee race.

Jonathan Bomarito and Harry Tincknell return, with Indycar star Ryan Hunter-Reay joining for Daytona. The Mazda showed incredible one lap pace at the test, with this entry in the top two for the first five sessions across Friday and Saturday. Fifth in the qualifying session was disappointing, but the car showed enough to suggest they have the pace to win. Now they need the reliability over 24 hours.

#77 Mazda Team Joest Mazda RT24-P: Oliver Jarvis/Tristan Nunez/Olivier Pla

This #77 stole the headlines from the pre-race test, setting an unofficial lap record during the Roar qualifying session. Frenchman Olivier Pla bettered team mate Oliver Jarvis lap record from qualifying last year by 0.074s.

Jarvis and Tristan Nunez are the full season drivers, with Pla joining for the Rolex. All three are seriously quick and experienced with the Mazda, and make a formidable combination.

Completing over 165 laps across all three days, allied with their extreme pace they showed will make them pre-race favourites based on the testing form. Reliability will be the key for Mazda, as they have failed to score a top six finish at the Rolex 24 in the past five years.

#85 JDC-Miller Motorsport Cadillac DPI-V.R: Matheus Leist/Chris Miller/Juan Piedrahita/Tristan Vautier

This #85 entry is rebounding from a difficult 2019 season. The team struggled despite a good Cadillac DPI package, with their best result of fifth coming in the Rolex 24. The other side of the garage has stolen the headlines with the recruitment of Mustang Sampling, but this entry is full of potential also.

Tristan Vautier and Juan Piedrahita are the full season drivers, and are joined by Indycar prospect Matheus Leist and Chris Miller for Daytona. Vautier is the standout here, with Leist and Piedrahita providing youth and plenty of pace.

The team had a very solid Roar, with sixth in the qualifying session. The team has shown potential and reliability, but they appear to lack a few tenths from the ultimate contenders. A podium would be a great result for the #85 crew.

That wraps up this preview for the Rolex 24 and the DPI class. Despite only eight entries every one of them has a chance of a podium. With three makes competing for the famed Rolex watch, let the sprint race commence.
