Must read

Anthony Davidson is again on the wheel of a prototype, only a 12 months and a bit on from his retirement from the cockpit. And he now understands the challenges confronted by the drivers out on observe within the World Endurance Championship aboard the successors to the LMP1 equipment by which he carved out a stellar sportscar profession.

“They’re having to wrestle the steering wheel way more than I ever did,” he reckons. “So that they’re positively incomes their cash on the market.”

The 2014 World Endurance Championship title winner with Toyota involves that conclusion after a handful of laps across the 8.47-mile Circuit de la Sarthe aboard Peugeot’s 9X8. Solely he’s a superb 100 miles to the north-east of Le Mans, on the outskirts of Paris at Peugeot Sport’s Satory base in truth.

His expertise of the French producer’s Le Mans Hypercar is firmly within the digital realm. He’s simply sampled the hybrid machine with which Peugeot is aiming to repeat the successes of its 905 Group C contender and the LMP1s he raced in 2010-11 – two generations of 908 turbodiesel – not on the race observe however in a simulator. 

Davidson describes his handful of laps within the Peugeot sim as a “actual eye opener”. It provides him a really feel for a breed of automobile designed to look totally different, lap slower and, crucially, be more cost effective than the high-tech LMP1 rocketships they changed.

“The vehicles are positively thrilling to have a look at and the Peugeot has a unusual look as a result of it doesn’t have a rear wing – one of many beauties of the brand new guidelines is the liberty it provides the designers,” says Davidson. “It was good to get an opportunity to drive the 9X8 within the sim to know a bit extra about it and simply how totally different the brand new vehicles are to the prototypes I drove throughout my profession.”

They’re vehicles that, till the journey to Paris, he’d solely witnessed at shut quarters from the cockpit of the LMP2 ORECA he drove in his last 12 months of racing within the WEC with the Jota group in 2021, and from barely additional away within the commentary field the place he has been the skilled voice on WEC TV because the begin of final season. His try-out in environment just like those he experiences each week in his ongoing function as one of many mainstays of the Mercedes Components 1 group’s simulator programme confirms that issues have modified since his days of racing in LMP1 with Aston Martin, Peugeot and Toyota between 2009 and 2017.

An LMH, just like the LMDh prototypes from Porsche and Cadillac becoming a member of the WEC this 12 months, is heavier, has much less downforce and fewer mixed energy from the interior combustion and front-axle hybrid factor of its powertrain than the earlier era of prototypes. And in contrast to the final two iterations of the Toyota LMP1 hybrid that Davidson raced, it’s not actually four-wheel drive in any respect. The benefits that include all-wheel traction have been just about eliminated as a part of the convergence course of designed to align the efficiency of the LMHs with the rear-hybrid LMDhs.

The minimal weight of four-wheel-drive LMH is 1040kg, although each the Peugeot and Toyota raced considerably larger than that below the Stability of Efficiency final season. The Peugeot topped out at 1079kg, the Toyota at 1071kg. That compares with the 870kg base weight of the LMP1 within the days when Davidson and his team-mates have been battling Porsche and Audi for supremacy on the entrance of a hotly contested WEC. 

“An LMH is certainly not as nimble and agile as the P1s I drove, nor the LMP2 I raced on the finish of my profession, however with the additional weight that’s to be anticipated. It’s easy physics” Anthony Davidson

“I did get a way of the mass of the automobile and the inertia that comes with it right away,” says Davidson, who has a fast spin early in his run out of the Ford Chicane. “That was me struggling to sluggish the automobile down as I used to be getting used to it after which hitting the kerb. I’ll permit myself one spin on a sim model new to me, however the automobile positively doesn’t like heavy braking and altering route on the identical time. When you’ve got a second and slide the automobile, it slides for longer than you assume it ought to. It doesn’t like being thrown round.

“I might actually really feel the load within the Dunlop Curve and the sequence after the chicane main as much as Tertre Rouge. It took me a few laps to take the Dunlop Curve flat. I assumed, ‘Whoa, this factor desires to understeer after I need to be squaring it up for the left into the chicane’. 

“The proper-hander out of the chicane and over the forehead of the hill was a extremely intimidating nook. Then on the backside of the hill, within the left-right that takes you up in direction of Tertre Rouge earlier than the Mulsanne Straight, I might actually really feel the pendulum impact attributable to the load. An LMH is certainly not as nimble and agile as the P1s I drove, nor the LMP2 I raced on the finish of my profession, however with the additional weight that’s to be anticipated. It’s easy physics.”

The burden of the automobile is just one of many issues that come as a tradition shock to Davidson, though his driving surroundings is one way or the other acquainted. The Peugeot sim, a system developed in-house by the Stellantis model, has been constructed up across the monocoque from a V8-powered 908. That’s the automobile generally referred to by its inside codename, the 90X, and a machine by which the Briton received three races within the 2011 Intercontinental Le Mans Cup that led into the rebirth of the WEC the next 12 months. The bathtub was written off in an accident throughout testing, subsequently constructed up as a present automobile after which given one other lease of life within the sim.

Davidson will get behind the wheel of the hybrid with sure preconceptions about what the front-only system on the newest Peugeot prototype would give him as a driver.

“There’s one thing about driving a four-wheel-drive hybrid that have to be hardwired into me,” he explains. “My mind was telling me that I’d have traction on the entrance to offer me additional stability on nook exit, however I didn’t really feel any four-wheel drive in any respect.” 

That’s as a result of the velocity at which electrical energy from the front-axle motor generator unit may be deployed is now strictly managed. The unique minimal on the introduction of LMH in 2021 was 120km/h (75mph), however from final 12 months it turned half of the system of Stability of Efficiency central to the brand new period of sportscar racing that begins with the Sebring 1000 Miles on 17 March.

The Toyota ran to a 190km/h (118mph) minimal in 2022, the Peugeot on its arrival within the sequence at Monza in July 150km/h (93mph), as a result of it runs wider entrance wheels and tyres and narrower rears than its Japanese rival. It modifications the entire dynamic of driving a prototype of right this moment in contrast with what got here earlier than.

“You haven’t received the entrance wheels clawing away on the floor of the observe, which gave these Toyotas I drove a lot stability,” factors out Davidson. “There was an understeery really feel to the Peugeot within the sim, when you might additionally really feel the rear finish squirming away on the ability. Having a automobile that I knew was a hybrid snapping round on the rear was counter-intuitive for me.

“You’ve received corners like Tertre Rouge and exiting the Porsche Curves the place you might be within the velocity vary for the four-wheel drive to in idea be kicking in, however you’ve received a lot downforce at these speeds that you just aren’t traction restricted. 4-wheel drive wouldn’t offer you a lot of a bonus at these factors on the observe.”

Within the new period, a clearly outlined torque curve is laid down for every automobile within the BoP forward of each race. The 200kW (260bhp) most energy allowed from the MGU doesn’t are available in on prime of the 500kW (670bhp) allowed from the interior combustion engine. That 500kW determine for Le Mans – and 520 for different WEC races – can also be most whole energy allowed, regardless of how a lot the MGU on the entrance is working.

“Getting on the ability was actually attention-grabbing, and evening and day in contrast with the four-wheel-drive Toyota LMP1 vehicles I drove,” continues Davidson. “In my day we handled the throttle like a change – you could possibly simply mash the pedal. It had a really small vary of journey as a result of it didn’t want it.

“We had a large quantity of torque within the {old} days, as a result of we had the ability from the traditional engine after which the hybrid system on prime of that. We had 500bhp from the combustion engine and at one stage one other 500bhp from the hybrid after we wanted it, which was normally on nook exit.”

The best way that the torque is available in from the Peugeot’s 2.6-litre twin-turbo V6 is one thing that strikes Davidson on his transient acquaintance with the 9X8.

“There’s an enormous visible affect once you have a look at a automobile and not using a rear wing as a result of we’ve all grown up seeing wings on the again of racing vehicles, however this automobile develops its downforce by ground-effects” Anthony Davidson

“Peak torque was at surprisingly excessive revs,” he explains. “At first I felt I might labour a taller gear for a lot longer and it could nonetheless ship sufficient torque. I realised after a number of laps it was higher to rev it, so you find yourself hovering fairly near the shift level a number of the time. That makes catching slides and snaps a bit extra tough.” 

There are a few last questions that should be requested of Davidson after his return to the cockpit of a up to date prototype. One is particular to the 9X8: did he really feel the absence of the rear wing when driving the automobile?

“I didn’t even give it some thought after I was within the sim,” he responds. “Certain there’s an enormous visible affect once you have a look at a automobile and not using a rear wing as a result of we’ve all grown up seeing wings on the again of racing vehicles, however this automobile develops its downforce by ground-effects. If you happen to can stability the automobile and not using a wing on the again, why not?”

And has his transient time within the Peugeot sim whetted his urge for food for a comeback in sportscar racing’s new golden age?

“I do know the Peugeot has air-conditioning, one thing the Toyota by no means had, so it could have a little bit of creature consolation for an {old} man like me,” he says. “However I’ve completed my time on the race observe: I’ll discuss what I see occurring on the market on TV as a substitute.”
