The GTD class, based around GT3 spec cars, has proved a great addition to the IMSA WeatherTech championship in recent years. It returns in 2018 stronger than ever, with 21 cars entered for the season opening Rolex 24. There is an increased international presence this year, and this only enhances the class battle that is likely to take place across the entire 24 hours.

Let’s take a look at the first half of the entry list.

#11 GRT Grasser Racing Team Lamborghini Huracan GT3: Mirko Bortolotti/Rik Breukers/Rolf Ineichen/Frank Perera

The Austrian team have established themselves as the leading Lamborghini GT3 racing team on the planet, having been front runners in ADAC GT Masters and Blancpain GT champions in 2017. The team return to the Rolex 24 after making their debut last year, and have brought with them two very strong entries.

In this #11 car is Mirko Bortolotti, Rik Breukers, Rolf Ineichen and Frank Perera. Bortolotti has developed into one of the fastest GT3 racers in the world with this team, with young Dutchman proving very quick in the one-make Lamborghini Super Trofeo category. Rolf Ineichen is a developing talent and Frank Perera was often one of the biggest thorns for this squad in the ultra competitive Blancpain GT series for Mercedes. Fastest time at the Roar test highlights how strong this team will be in the race.

#14 3GT Racing Lexus RC F GT3: Dominik Baumann/Phillipp Frommenwiler/Bruno Junqueira/Kyle Marcelli

It’s all change for the Paul Gentilozzi 3GT Racing team this year, after a difficult first year as a factory Lexus team. IMSA rules have forced the team to become independent of Lexus for this year, although the team have retained a strong driver line-up.

Dominik Baumann is a promising young Mercedes factory GT driver who joins the team for the full season. He will be partnered by Kyle Marcelli, a quick driver who has raced in various American GT series over the past few years.

Joining them for Daytona will be Bruno Junqueira and Philipp Frommenwiler. Junqueira is a quick and experienced sportscar racer and Frommenwiler proved quick in the International GT Open series with this car last year.

#15 3GT Racing Lexus RC F GT3: Dominik Farnbacher/Jack Hawksworth/David Heinemeier Hansson/Scott Pruett

This #15 has a similarly strong line-up to it’s sister #14 entry, and now have a years experience with the car to help them move up the grid. Expect to see an improvement from this team this year, with a possible top six result achievable for the team.

On the driving front the team retain former Indycar racer Jack Hawksworth, but he will be partnered for this year by Dane David Heinemeier Hansson. He has established himself as one of the quickest amateur sportscar racers in the world, and moves across from the Rebellion WEC LMP2 team.

Dominik Farnbacher rejoins the team after racing for them at this race last year, with Scott Pruett completing the line-up. Joint record winner of the Rolex 24, Pruett recently announced that this will be his final race before retirement. The team will be doing everything it can for him to go out on a good result.

#19 GRT Grasser Racing Team Lamborghini Huracan GT3: Christian Engelhart/Christoph Lenz/Louis Machiels/Ezequiel Perez Companc/Max van Splunteren

The Lamborghini entries have looked the class of the field in pre-race testing, which bodes well for this #19 GRT Grasser entry. The team are Lamborghini experts and return with experience of this race from last year. Whilst this driver line-up may not contain the overall quality of the #11 entry, this is still a contender for class victory.

Christian Engelhart heads the driving crew, look for the car to be very quick in his hands. Ezequiel Perez Companc showed flashes of promise last year in Blancpain for the team, with Max van Splunteren an ever improving silver rated driver. These have become increasingly crucial in pro-am classes such as GTD. Christoph Lenz and Louis Machiels are two gentlemen drivers who bring plenty of GT racing experience.

#29 Montaplast by Land Motorsport Audi R8 LMS: Kelvin van der Linde/Sheldon van der Linde/Christopher Mies/Jeffrey Schmidt 

The German Land Motorsport team have risen massively in the past few years to become one of the premier Audi customer GT teams on the planet. After success in Europe the team make their full season debut in the IMSA series after several one-off entries last year that culminated in a class win at the season finale Petit Le Mans race.

South African brothers Sheldon van der Linde and Audi factory driver Kelvin will team up for the full season, and are ably supported by Christopher Mies and Jeffrey Schmidt. Mies won the Nurburgring 24 Hours with the team last year and is a very quick factory GT racer, with Schmidt well known to the team after a top ten ADAC GT Masters season with them last year. This team came within 0.3s of winning last year, so will hope they can be in the hunt again this time around.

#33 Team Riley Motorsport Mercedes AMG GT3: Ben Keating/Jeroen Bleekemolen/Adam Christodolou/Luca Stolz

The Riley motorsport team are a recent mainstay of American GT racing, returning for another year of IMSA racing with their Mercedes AMG GT3 car. The long term pairing of Ben Keating and Jeroen Bleekemolen are coming off a standout year, with class victory at the Sebring 12 Hours and a close 2nd place finish in the championship.

They are joined for the Rolex 24 by Mercedes factory driver Adam Christodolou and his Blancpain GT team mate Luca Stolz. Christodolou was key to their third overall result last year with developing young driver Stolz the team can hope to achieve another class podium this year.

#44 Magnus Racing Audi R8 LMS: Andy Lally/John Potter/Andrew Davis/Markus Winkelhock

The John Potter run Magnus racing team have proven very popular since their inception in 2010. After a year away from IMSA racing in the Pirelli World Challenge, the team return this year for another full season effort.

Long term team mates John Potter and Andy Lally are very experience and with the support of Lally Potter is improving as a driver every year. Joining them for the endurance rounds is another experienced Audi racer, Andrew Davis. Factory Audi GT driver Markus Winkelhock adds some star power to this team, watch out for him at the wheel. A win on their debut would be the dream storyline for the team, but a top six result would be a great result in their first race back at this level.

#48 Paul Miller Racing Lamborghini Huracan GT3: Andrea Caldarelli/Bryce Miller/Bryan Sellers/Madison Snow

The Paul Miller racing team return this year as the only team running a full season programme with the Lamborghini Huracan. The Italian car has struggled to match its success in Europe in the IMSA series but the team are sticking with what they have this year.

This also applies to their regular season pairing of Bryan Sellers and Madison for the third consecutive year. The team finished ninth last year with one podium but the Rolex 24 is always an anomaly at the start of the year, so the team could spring a surprise with a class podium if they can keep out of trouble. The team are bolstered for Daytona by Lamborghini factory driver Andrea Caldarelli and Bryce Miller. In Caldarelli’s hands the car will fly and Miller provides speed and experience at this level.

#51 Spirit of Race Ferrari 488 GT3: Pedro Lamy/Mathias Lauda/Daniel Serra/Paul Dalla Lana

The Spirit of Race, factory AF Corse supported team have filed a very strong single-car entry for this years Rolex 24. The team have vast experience from racing in Europe and in the WEC, with the Ferrari 488 proving a very competitive package last year also.

In terms of driving talent, with team have signed a bevy of drivers who are usually associated with Aston Martin’s. All four drivers have strong connections to the British marque, with Lamy, Lauda and Dalla Lana all WEC GTE Am champions last year. Brazilian Serra won the GTE Pro class at the Le Mans 24 Hours as a factory Aston Martin driver. All four are very quick with Dalla Lana a very competent am, which is a crucial part of this pro-am class.

#58 Wright Motorsports Porsche 911 GT3 R: Mathieu Jaminet/Patrick Long/Christina Nielsen/Robert Renauer

Porsche racers Wright Motorsports return to the IMSA series this year after winning the Pirelli World Challenge title last year. Porsche factory driver Patrick Long returns to the team this year, and the team have partnered him with two-time reigning class champion Christina Nielsen.

The signing of Nielsen is a real coup for the team and gives them one of the strongest pairing for the season. For the Rolex 24 the team have drafted in Porsche factory driver Mathieu Jaminet and experienced Porsche customer GT exponent Robert Renauer. This team has a very strong driver line-up, ensuring that if they run cleanly they almost certainly be fighting for the win come Sunday afternoon.

#59 Manthey Racing Porsche 911 GT3 R: Matteo Cairoli/Sven Muller/Harald Proczyk/Steve Smith/Randy Walls

Porsche’s WEC GTE factory team Manthey Racing have put together this customer programme for this years Rolex 24. The team are one of the leading Porsche motorsport teams on the planet, and the team have some very talented factory drivers heading this line-up.

Both Matteo Cairoli and Sven Muller are very quick young professional drivers who consistently shine at the wheel of Porsche GT cars. These two will be as quick as anyone in the class, but the other three gentlemen drivers will struggle to match their ultimate pace. Harald Proczyk makes the step up to this level after being a consistent top five runner in the burgeoning TCR Germany touring car series. Steve Smith has primarily raced in the German VLN Endurance series along with Randy Walls, all with the Manthey team.
