Wayne Taylor Racing means business in 2025 with its new-look Cadillac program in IMSA’s GTP class.

One year after upping the ante with Acura and HRC by adding a second car to its program, WTR packed its bags and signed a deal to return to General Motors. It was a big move, which is at the heart of Cadillac’s renewed push for glory in North America.

After a four-year partnership with Acura, this move promises to inject fresh energy into the Indiana-based team. Following a successful stint with the ARX-05, the team amassed just two race wins in two seasons with the ARX-06. They began craving change, and when the opportunity arose following Chip Ganassi Racing’s split with GM, they pounced.

For the start of this new chapter, Cadillac Wayne Taylor Racing is bringing two cars and a set of star drivers to the field. The No. 10 sees Ricky Taylor and Filipe Albuquerque pair up for the campaign. The sister No. 40, meanwhile, will be steered by Louis Deletraz and Jordan Taylor throughout the year. JOTA WEC drivers Will Stevens and Alex Lynn (who pulled out of the Rolex 24 with a virus) are in for the long races and Toyota Hypercar drivers Brendon Hartley and Kamui Kobayashi add further firepower for Daytona.

“The team has always had a reputation of hiring some great drivers, especially for the long races. We’re lucky we have that attractive nature,” Ricky Taylor told RACER.

“People want to drive with WTR and because of the relationship between the three Cadillac teams, we wanted to share drivers. That’s why we’ve got Alex and Will.”

WTR’s No. 10 remains a powerhouse of talent behind the wheel, and with the No. 40’s lineup being stronger than ever, we could see great success right out of the gate at Daytona once again. Brandon Badraoui/Lumen

How long will it take for the team to hit its stride again? History tells us it won’t be long. Back in 2021 when WTR transitioned from Cadillac to Acura it won the Rolex 24 on debut with the ARX-05.

Testing opportunities were limited over the short off-season, though, and the level in GTP is sky-high these days, with 12 cars in for Daytona and Aston Martin set to make it 13 for Sebring.

Good news is that, while the V-Series.R may be new to the team, the car is a known quantity. It was the same situation back ’21 when WTR paired with Acura after Penske campaigned the ARX-05 for three seasons.

Caddilac’s V-Series.R is a proven winner, claiming the 2023 IMSA GTP titles with Action Express and received its first “joker” update in the form of an electronics upgrade ahead of the new season.

There’s also plenty of track time for the team to make use of in the build-up to the Rolex for WTR’s staff to play around with setup options and familiarize themselves with the car’s finer details.

“It’s all quite new, and considering it’s the same rules package for everybody, the different manufacturers have definitely gone about attacking the hybrid approach differently,” Taylor continues.

“The approach from GM, Cadillac and Dallara has always been to keep things simple, and I think that jumped out to me when I first drove the car. The Acura was nimble and agile, and that was by design with the smallest, lightest engine.

“But the Cadillac is simple; it does all the little things right and that’s what you need for endurance racing. We can already see why this car is good at every race track because, with every change you make to the setup, you feel it. It’s very adaptable.”

The toughest task may come on the human side, as WTR’s crews develop a working relationship again with everyone at Cadillac and chassis supplier Dallara.

“For us, it’s drag and drop in terms of staff, but from the factory side, it’s all changed so much from the DPi era,” Taylor, who last drove a Cadillac way back in 2017, explained. “Back then you would get an engine guy from GM, a performance guy from Dallara and that was pretty much the relationship between the team and those partners.

“Now it’s a combination of 100-plus people across the different companies, so it’s still a learning curve and, in some ways, it doesn’t feel like a homecoming, you feel like a stranger. It’s interesting to see how everything has evolved, as GM is putting more resources into this than ever.”

With WTR back in the Cadillac fold, GM now has two major players in their pocket. Action Express, a longtime partner, is ready to help jumpstart the returning stablemates’ program. Jake Galstad/Lumen

If it does take time for WTR to get up to speed, then Cadillac can turn to Action Express. The loyal Gary Nelson-led team remains part of the family with a single car and a head-turning line-up. Full-season driver Jack Aitken expects the two teams to work closely throughout the season, which should, in turn, also help WTR hit the ground running in the early part of 2025.

“We’re trying to make it all even more cooperative at Cadillac than it was before,” Aitken says. “That’s not necessarily because of the swap of Ganassi and Wayne Taylor, that’s just what Cadillac is always trying to foster. We are trying to increase data sharing, communication and our general understanding.

“It’s difficult because there are so many people involved, and it’s not easy to act cooperatively on the race track, but that’s the aim going forward. We are Cadillac teams and Cadillac drivers and the goal is for Cadillac to be on the top step above all else.

“We will see how it plays out when we start racing for real, but right now it feels very positive.”

United leads Bronze-only session to wrap up 2025 Roar at Daytona

The 2025 Roar Before The Rolex 24 came to a close Sunday afternoon with a quiet, Bronze-only test session on the drying Daytona International Speedway surface.

Just 20 cars across three categories — LMP2, GTD Pro and GTD — took part, with United Autosports leading the way with Daniel Goldburg in the No. 22 ORECA — his best lap a 1m40.613s, 75 minutes into the session.

There were multiple improvements late on with the entire field on slick tires. George Kurtz in the No. 04 Crowdstrike ORECA rose to second with a 1m40.858s.

Nick Boulle, fresh from signing a full Endurance Cup deal with United, put the No. 2 ORECA third, while Jon Field found time in his final run and ended up fourth with a 1m41.468s from Inter Europol.

In GTD, Anthony McIntosh set the benchmark time in the No. 19 Van der Steur Racing Aston Martin Vantage GT3 Evo, a 1m48.459s. Kenny Habul put the No. 75 75 Express GTD Pro Mercedes second.

[lawrence-auto-related count=3 category=1406]

After three days of testing, the quickest overall time went to Dries Vanthoor in the No. 24 BMW Team RLL M Hybrid V8 in GTP — a 1m35.424s set during the second session on Friday.

In LMP2, it was newly-minted Peugeot Hypercar driver Malthe Jakobsen who set the pace for Crowdstrike Racing by APR. The Dane’s best tour was a 1m38.673s in the opening session Friday. Notably, that time was quicker than the slowest of the GTP drivers — Bryce Aron — whose best lap was a 1m38.713s in the JDC-Miller Porsche.

GTD Pro saw Pfaff Motorsports enjoy a rapid start to life as a Lamborghini customer team. Its No. 9 Huracan lapped Daytona in 1m47.626s with Andrea Caldarelli at the controls in Friday’s opening session. That edged out defending champion Laurin Heinrich by 0.15s in the AO Racing Porsche.

A Lamborghini also topped GTD. Forte’s No. 78 Huracan managed a 1m48.036s on Saturday morning with Franck Perera installed. The time was marginally quicker than Rahel Frey’s in the No. 83 Iron Dames Porsche in the first session of the test by just under 0.05s.

Track action for the IMSA WeatherTech SportsCar Championship resumes after a three-day break on Thursday. The Rolex 24’s first free practice will start at 10:05 a.m. local ahead of qualifying later that afternoon.

MSR and Acura: The band is back together and stronger than ever

It’s been an emotional weekend in Daytona for Meyer Shank Racing. Back in the IMSA WeatherTech SportsCar Championship paddock following a year-long pause due to HRC US’s shift to a single-team approach in GTP with Wayne Taylor Racing in 2024, the Ohio-based outfit is charged up and raring to go.

“I was at Chipotle when I got the call last year, standing there with a brown rice bowl,” team owner Mike Shank told RACER.

“It was David Salters (HRC US’s president) and he said, ‘We’re getting the band back together!’

“I was just overjoyed. I called my wife, I called Jim Meyer, and then the rest of the group. More than anything, I was just proud.

“After the issue (post-Daytona) in 2023, we carried on with life, as tough as it was, came back strong late in the year and would have won the championship (had MSR not received a points deduction for manipulating tire pressure data at the Rolex 24). So I was proud when I found out, more than anything, after so much work.”

Colin Braun, Tom Blomqvist, Helio Castroneves and Simon Pagenaud took MSR and Acura to a commanding Rolex victory in 2023, but controversy overshadowed it in short order. Now, after a year apart, the two organizations are back together with a lot of familiar faces behind the scenes. Richard Dole/Motorsport Images

Acura Meyer Shank Racing is back and — in terms of the size of its program at least — better than ever, with two GTP class ARX-06s and a refreshed driver lineup.

Its full-season driver pool combines returnees Colin Braun and Tom Blomqvist with the new faces of Renger van der Zande, formerly of Cadillac, and Nick Yelloly from BMW Team RLL. For the Rolex 24, the roster expands further, too, with MSR IndyCar regular Felix Rosenqvist, Honda factory driver Kakunoshin Ohta and, courtesy of a deal with Chip Ganassi Racing, Alex Palou and Scott Dixon.

“We all work together on choosing drivers,” Shank said. “We did some number crunching and looked at historic performances and results.

“I had two guys on the No. 60 car that I felt deserved a real shot again with Tom and Colin, that was a no-brainer. Nick and Renger are two guys I’ve known for a long time and competed against.

“For me, they were super solid, fast veteran guys for the No. 93 who know how these cars behave.”

The majority of the team’s 2023 engineering staff are also back for the comeback tour.

“[All of them] deserve to be here,” he continued. “We’ve lost one person from the total group of 23, that’s it. They’re all back with us in different forms, plus we’ve added some new people to strengthen this.

“This model is interesting for us, with us leading the engineering on one car and HRC leading the other. It makes for a strong team effort and we look forward to ironing out the creases and getting our communication channels smooth, which is tough when you have 100 people.”

HRC President David Salters made the magic phone call to get the band back together and, as always, packs the program with some of the best engineering investment in the series. Michael Levitt/Lumen

While the ARX-06 has matured since MSR’s last IMSA race, particularly on the software side, the car is essentially identical on a nuts and bolts level.

Shank says the software updates haven’t counted as a “joker.” This should help the team hit the ground running, particularly in the early part of the season.

“Acura has spent a lot of money getting to this point, so the propensity to go and spend more to develop a BoP car doesn’t make a lot of sense,” he added. “It’s all moving forward and there’s AI coming in now, so we’ve had to make sure we’re up to snuff on that.

“We’ll keep an open mind and, when it’s time, I’m sure we will put something together.”

Following a productive weekend of testing at the Roar — with both cars completing plenty of laps — the level of expectation hasn’t been lowered at all.

“We expect to come back on the podium,” Shank said. “Maybe we don’t win, but there’s no reason we shouldn’t be challenging for the podium places.”

The weather changed for Sunday’s second IMSA VP Racing SportsCar Challenge 45-minute race at Daytona International Speedway. However, the winners in all three categories did not, as each driver showcased their skills in drastically different conditions.

After racing under sunny and warm skies on Saturday, dark and wet conditions greeted the field Sunday as teams ran on Michelin wet-weather tires. Each of the winners, Valentino Catalano in Le Mans Prototype 3 (P3) and overall, Adam Adelson in Grand Touring Daytona X (GTDX) and Kiko Porto in Grand Sport X (GSX) met the moment as the race evolved on a drying track.

Catalano controls P3 competition

Jake Galstad/IMSA

Driving the No. 30 Gebhardt Intralogistics Motorsports Duqueine D08, Catalano led all but one of the 21 laps from pole as the track slowly dried out. The only time he wasn’t out front came after a restart when Brian Thienes, in the No. 77 Forte Racing Ligier JS P320, got the jump on the tri-oval on Lap 8. Catalano quickly repassed him on the outside one lap later and never looked back, leading the team’s second 1-2 finish in as many races to start the year.

“I was the first guy who went in these conditions, so it was really tricky,” Catalano said. “I went calmly in the beginning, saw I could off a gap and saw some guys make mistakes. The conditions were difficult, but it worked out for me, so I’m happy.

“It was damp, but not completely wet, so the tires were hot and therefore I got less and less grip. So, it was just driving smoothly and trying out the lines.”

Teammate Markus Pommer, in the No. 31 Gebhardt Intralogistics Motorsports Duqueine D08, finished second only 2.273s in arrears. Despite going off course a couple of times, he managed to keep going without damage or losing too much time.

Jonathan Woolridge was third in the No. 54 MLT Motorsports Ligier JS P320 with Thienes fourth among P3 cars and the top Bronze-rated finisher.

Adelson adds second straight GTDX class debut

In GTDX, Adelson’s No. 24 Wright Motorsports Porsche 911 GT3 R (992) was again the class of the field. After winning by more than 30s in the dry on Saturday, Adelson’s winning margin was a nearly equivalent 26.324s on Sunday.

Like Catalano in GTDX, he only lost the lead on lap eight as Kyle Washington powered past in his similar Porsche, before Adelson regained the top spot into the Le Mans Chicane on the inside of lap nine.

[lawrence-auto-related count=3 category=1406]

“You’re trying to feel the grip on the out laps, trying to learn what it’s like out there and what you can or can’t get away with,” Adelson said. “I think I came under threat a bit just because I was struggling a bit with the P3 cars at the start. But they don’t have (traction control) or ABS, so they’re rightfully more cautious and because we’re heavier, we can also get our tires up (to temperature) more quickly. Hoping to be back here a third time to step onto the podium when it matters the most!”

Af Corse teammates Matias Perez Companc and AJ Muss in their Nos. 50 and 66 Ferrari 296 GT3 cars completed the GTDX podium, with Muss starting first in class. Washington, in the No. 32 GMG Racing Porsche, ended fourth among GTDX cars and was the top Bronze-rated driver ahead of Samantha Tan, who was second in Bronze for the second straight day in her No. 38 ST Racing BMW M4 GT3.

Porto pushes past penalty for GSX encore

Jake Galstad/IMSA

Multiple drivers saw their races go awry Saturday when assessed a 10-second time penalty by IMSA officials for a false start, improperly changing lanes and starting from the wrong column. Porto got the same penalty as those drivers on Sunday but avoided the same setback result.

Driving the No. 8 RAFA Racing Toyota GR Supra GT4 EVO2, Porto took the lead on lap four, briefly lost it on lap eight to his Saturday sparring partner Steven Clemons (No. 76 BSI Racing Toyota GR Supra GT4 EVO2), then regained it on lap nine before working to set sail on his rivals. Running laps 2-3s faster a lap, Porto was able to bank the gap to an eventual 21.283s margin, which was enough to offset the 10s penalty applied post-race.

“Once I heard what was happening, I knew I needed to go through the field as fast as possible and open a gap, and then another yellow came,” Porto said.

“My restart was not very good. I had some cars to pass, I got it done, and then it was difficult for me to open the gap. There’s GT3 and LMP3 cars around, so I was seeing how to be fast without taking too much risk and not compromise. Thankfully this Toyota Supra was one of the best cars I’ve ever had in my career.”

Jackson Lee drove through the field to second in the No. 2 CSM Porsche 718 GT4 RS CS while Porto’s RAFA Racing teammate, Ian Porter in the No. 68 Toyota GR Supra GT4 EVO1, finished third in GSX and first among Bronze-rated drivers.

The VP Racing SportsCar Challenge resumes with rounds three and four of the season as part of the NASCAR Cup Series weekend at Circuit of The Americas in Austin, Texas, February 28 through March 1, 2025.

Proton Porsche slithers to a wet lead in sixth Roar session

Proton Competition’s No. 5 Porsche 963 set the fastest time in Sunday’s rain-soaked sixth IMSA Roar Before the 24 session, which got underway at midday rather than 9:45 a.m. due to heavy rain, thunder and lightning trackside.

Neel Jani set the best time, a 1m45.433s, to go 0.4s up on the other privately entered GTP car in the field, the No. 85 963 from JDC-Miller that took second. Gianmaria Bruni was fastest in the “Banana Boat” which completed just eight laps, the fewest in the class. The Italian’s hot lap was a 1m45.879s.

While the fastest lap times were nowhere close to the best from the dry running, the session —  hit by multiple rain showers — did hand the teams a chance to familiarize themselves with the circuit in wet conditions for the first time.

“For us, we decided to drive because we haven’t had any experience in Daytona in the wet with the car,” Jani said. “So we tried it out to see how the tires develop and gather data. In the beginning, there were dry patches but after that, it got worse. It was good to learn.

“Laps are laps, but next week it looks like it could be wet for qualifying day, so it could be useful.

“I think Turn 1 is a tricky one in the wet — as you cross the rubbered line it gets very slippery. That’s why you saw a lot of cars locking up under braking.”

[lawrence-auto-related count=3 category=1406]

The No. 31 Whelen Cadillac ended up third after a 1m46.240s tour from Jack Aitken. The car did hit minor trouble during the hour when Felipe Drugovich was spotted by TV cameras limping back to pit road with a right-rear puncture.

RLL BMW wound up fourth with the No. 25 and the No. 60 Meyer Shank Acura ran fifth.

In LMP2, despite both its cars suffering spins, United Autosports USA managed to place its two ORECAs in the top three on the timing screens. Peugeot Hypercar driver Paul Di Resta put the No. 22 at the top of the pile with a 1m49.870s — the only time under 1m50s in the session. United’s No. 2 ended up third.

The No. 11 TDS Racing ORECA split the two, with a 1m50.440s from Mikkel Jensen.

Inception Racing’s No. 70 Ferrari set the pace in GTD with a 1m57.033s from Ollie Millroy. Franck Perera placed Forte’s Lamborghini second. Further down the order, the fastest GTD Pro car — the No. 3 Corvette — would end up sixth in the combined ranking.

There were multiple red flag stoppages in the session, including one for the No. 5 Proton Porsche spinning at pit-in, as well as the No. 22 United ORECA looping around at Turn 1, plus one for heavy rain that brought the session to a premature end with 3.5m left on the clock.

One more Roar session remains, as teams are currently waiting on news of when it will get underway due to the weather delays.

Saturday’s IMSA testing action at Daytona came to a close with the teams’ first bout of night running under the floodlights.

After BMW Team RLL paced GTP during the day, it was Porsche’s turn to top a session come nightfall. Laurens Vanthoor completed a 1m36.498s to put the 2024 title-winning No. 7 963 in the prime position on the leaderboard.

The time wasn’t quite quick enough to better his brother Dries’ 1m35.424s hot lap from Friday in the No. 24 M Hybrid V8, the fastest lap of the Roar Before the 24 so far. And with weather forecasts for Sunday’s track action predicting rain, that time looks likely to be the fastest time of the entire weekend.

BMW ended up slotting in second and third in the standings, with the No. 24 0.4s quicker than the No. 25. Philipp Eng was the quickest driver from the team with a 1m36.498s.

LMP2 saw Antonio Felix da Costa lead the charge for Inter Europol Competition. The Le Mans-winning Polish team, which is competing on its own in IMSA this year, would end the night 0.3s up on the field with a 1m39.618s. The No. 11 TDS and No. 73 Pratt Miller examples completed the top three.

[lawrence-auto-related count=3 category=1406]

Further down the list in LMP2, the No. 18 Era Motorsport ORECA brought out a red flag toward the end of the night running after Tobias Lutke had an off at Turn 3.

It was all Porsche in GTD, with the top four spaces in the combined rankings all filled by 911 GT3 R 992s. Thomas Preining’s 1m48.034s put the No. 20 Proton example atop the timing screens.

Wright’s Porsche slotted in second and was quickest in GTD with a 1m48.140s. AO’s “Rexy” Porsche ended up third and the Iron Dames took fourth.

Best of the rest was AWA’s Corvette, which was third fastest in GTD. It was incredibly tight, with all but five of the 36 GTD and GTD Pro cars that set times all lapping in the 1m48s.

The penultimate session of the 2025 Roar is set to go green at 9:45am ET.

BMW’s time at the top of the timing screens continued in Session 4 at Daytona this afternoon, with the No. 25 M Hybrid V8 finishing the hour-long session first, following a 1m36.196s from Sheldon van der Linde.

It was a 1-2 on this occasion for the RLL team, with Dries Vanthoor putting the No. 24 second with a 1m36.600s.

“It’s positive to see that all the hard work over the winter is paying off,” van der Linde said after the session. “It’s only the Roar — we know a lot of people are sandbagging quite a lot, but it’s a good way to start the event. The car feels good.

“We didn’t know where we would be, and everyone’s doing something different with programs. But we expect to be stronger this year. The team has taken steps forward, with new engineers bringing the knowledge of other cars over.”

The two Penske Porsches came closest to breaking the deadlock, with Mathieu Jaminet putting the No. 6 third and Nick Tandy steering the No. 7 963 to fourth with 1m36.9s and 1m37.1s laps respectively.

The No. 40 WTR Cadillac completed the top five, with Jordan Taylor logging the car’s fastest time, a 1m1:37.237s.

[lawrence-auto-related count=3 category=1406]

In LMP2, Tom Dillmann reeled off a 1m40.272s in the Inter Europol ORECA to lead the way. Reigning GTP drivers’ champion Dane Cameron was also quick, putting the AO Racing “Spike” ORECA second with a near-identical time — 1m40.279s.

Elsewhere in the class the No. 22 United Autosports 07 suffered the first significant incident of the Roar. Dan Goldburg lost the rear of the car at the Le Mans Chicane and ended up sliding sideways into the tires on driver’s left.

The impact, took the rear wing off the car, though overall the damage looked relatively minor when the car was lifted onto its flatbed during the subsequent red flag period.

Lamborghini looked strong again in GTD. Andrea Caldarelli set the best time in the GTD PRO-entered No. 9 Pfaff Huracan, a 1m48.049s.

The GTD pacesetter was Michelle Gatting in the Iron Dames Porsche. The Dane’s best lap was a 1m48.173s. Stevan McAleer in the No. 021 Triarsi Ferrari would end up third and within a tenth of Bovy.

The third and final session of the day will see the cars run in darkness from 6:30pm ET.

BMW’s form from Roar Before the 24 Session 2 yesterday continued in Session 3 today at Daytona, with the No. 25 BMW Team RLL M Hybrid V8 topping the times after a 1m36.798s from Marco Wittmann.

Wittmann’s hot lap came early in the session after multiple improvements and was just over a tenth faster than the other GTP drivers. It was, however, not quite as quick as Dries Vanthoor’s benchmark time from Friday’s action.

[lawrence-auto-related count=3 category=1406]

The No. 93 Acura MSR ARX-06 slotted in second after ex-Cadillac driver Renger van der Zande set a 1m36.928s. The No. 6 Penske Porsche completed the top three with a time that was also within two-tenths of the lead BMW.

The sister No. 7 Porsche — which lost out on valuable track time in Session 2 with a fault that set off the car’s high voltage alarm — was back on track today and ended up sixth in the times after initially sitting second early on. Nick Tandy set the car’s quickest tour, a 1m37.204s.

The quickest of the Cadillacs, meanwhile, was the No. 10 from Wayne Taylor Racing. It would finish up fifth, a tenth off the No. 60 MSR Acura that claimed fourth in the classification.

It was a productive session for the whole GTP field, with each of the 12 cars completing more than 20 laps. The highest mileage total was achieved by the No. 31 Whelen Cadillac, which managed 42 tours of the speedway.

In LMP2, Riley’s No. 73 ORECA topped the session with a 1m40.108s from Felipe Fraga in the opening minutes. The Crowdstrike by APR ORECA continued to show pace and took second.

A trio of Lamborghini Huracans paced the GTD classes with the No. 78 from Forte Racing, which set a 1m48.036s with Mario Farnbacher at the controls, coming out on top. The No. 45 from Wayne Taylor Racing was 0.156 off and second, its best time less than a tenth faster than the No. 9 from Pfaff, which was the quickest car in the GTD PRO field.

There was one red flag stoppage in the 90-minute session to allow circuit marshals to clear a WeatherTech advertising board that was dragged onto the circuit at the Le Mans Chicane by the Turner BMW.

The green flag running in the session was also interrupted by a simulation of the new-for-2025 category and class split procedure that will be used during full-course yellows this season. Once the 10-minute-long process came to a close, a faux race restart occurred with the Lamborghini SC63 leading the field across the line.

Session 4 is set to begin at 3:10pm ET.

Mercedes-AMG gets first taste of IMSA torque sensors during Roar

All WeatherTech SportsCar Championship GTD PRO and GTD cars are competing with torque sensors attached to their rear axles for the first time this season, as IMSA moves to adopt the same performance balancing strategy that is currently used for the …

All WeatherTech SportsCar Championship GTD PRO and GTD cars are competing with torque sensors attached to their rear axles for the first time this season, as IMSA moves to adopt the same performance balancing strategy that is currently used for the FIA WEC and ELMS LMGT3 classes.

As in GTP, these sensors — which feed live acceleration, horsepower and torque curve data to the series — have been introduced to assist the Balance of Performance process throughout the season. Despite the added cost for the teams (estimated to come in at around $250,000 a year per car) this move appears to have been welcomed by a large section of the paddock.

For the majority of the manufacturers involved, preparing for this change has been a relatively straightforward task. The components themselves are identical to the ones used in LMGT3 and all the hard work to get up to speed was done ahead of the 2024 FIA WEC season with lessons learned in the early races last year.

However, Mercedes-AMG — which wasn’t represented on the FIA WEC’s LMGT3 grid for the category’s inaugural season (and doesn’t compete with a prototype in Hypercar or GTP) — is totally new to this technology and its practical application heading into 2025.

As a result, it has some catching up to do early in the season and, specifically in Daytona, with the five AMG GT3s entered for the season opener.

“We are the manufacturer with the least experience with the sensors as we missed out on participating in WEC last year,” Stefan Wendl, head of Mercedes-AMG customer racing, told RACER ahead of the start of Roar Before the 24. “We know we start on a different level to the others, so we are trying to gather as much data as possible and make the best out of it.

“The Friday Roar sessions are the first time a Mercedes-AMG will hit the track with sensors under scrutineering conditions after private tests in Europe and Daytona. It’s an exciting moment and we have tried to prepare as best we can with our customers.

“We all expect and hope for a well controlled competition that helps the organization create a fair BoP across the season. These are expectations that I share with other manufacturers and the series.

“We will see how it evolves, but realistically I expect it will take a few races to come to a steady, controlled environment.”

Mercedes-AMG’s customer teams aren’t fazed by the task ahead. A number of hiccups made for a tricky start to the Roar on Friday, so there’s still some trepidation ahead of the first race of the season.

“There’s still work to do; there’s uncertainty,” Russell Ward, Winward Racing’s team principal and driver admitted. “But it’s something out of our control.

“It’s the biggest question mark going into the Rolex 24, as we have no idea what the reliability will be like or how it works. We’ve got a lot of really smart people, though, who will help optimize the system.

“The early sessions have seen some real difficulties and, as is all too often the case, identifying the problems, finding a fix and then optimizing the solutions becomes a real race against time at a point where we would rather be working on other things leading into such an important event.

“We are pushing super hard to claw back the time we are losing to the problem. We’re the reigning champions and we don’t give up easily.”
