Peugeot confident in upgraded 908

Peugeot is expecting its battle with Audi to be closer at this year's Le Mans 24 Hours than it was in 2009, as its 908 enters its fourth and final season

Peugeot confident in upgraded 908

The French manufacturer took its first win with the diesel 908 last year, at the third attempt, while the race was the debut for Audi's R15 TDi.

Peugeot Sport technical director Bruno Famin says the car has been updated for 2010 and expects a close race.

"Last year we believed we might be fractionally behind our main rival in terms of performance, but in reality it was quite the opposite and the 908 was still one step ahead," he said.

"It is quite clear that our rivals have responded and made significant progress with a car that is still only two years old. In terms of raw performance it wouldn't surprise me if we were very fractionally behind - and that will set things up nicely for a 24-hour sprint race at Le Mans."

Peugeot has been forced to make alterations to its engine cover and front diffuser 908 to comply with the 2010 aero regulations. The Le Mans organiser, the ACO, has continued its efforts bring the performance of petrol and diesel cars closer together, so the air restrictor has been reduced from 38.3mm to 37.8mm and the maximum turbo pressure lowered from 2.75 bar to 2.59 bar, resulting in an expected decrease of 40bhp.

But the team has continued to develop the power unit and other areas of the car.

"Engine developments have continued and we have upgraded the engine," said Famin. "We have particularly focused on the reduction of frictional losses thanks to groundwork ont he lubricants, improved volumetric effeciency for inlet and exhaust and enhanced combustion.

"We have also worked on a serious weight reduction programme. The target was to make sure the car was no heavier this year, despite the various changes that have been made in terms of both reliability and the latest bodywork regulations.

"Reliability was an important consideration, even though we've had only one retirement since 2007 - we've completed 191 of a possible 192 racing hours [at Le Mans]. It was important to maintain this tradition, so we began with a major overhaul of all the elements that caused us problems in 2009: gearbox, clutch and transmission, brake wear, wheel assemblies and air-conditioning.

"Finally, we have worked closely with Michelin on a completely new range of tyres for dry, intermediate and wet conditions."

The standout memories of Le Mans 2021

OPINION: With four of the five Hypercar entries unproven in a 24-hour race, it would not have been unexpected for at least one of them to suffer serious reliability trouble. That they all managed to make it through the race relatively unscathed, says GARY WATKINS, was something of a surprise.

The screaming rotary-engined Mazda 787 is regarded as one of the most popular Le Mans 24 Hours-winning cars, but until its surprise success on this day 30 years ago it was never regarded as a likely victor. But that reckoned without a new technical partner, some canny political manoeuvring and a rival's bizarre self-inflicted weakness
