McLaren F1 LM
'The fastest road car in the world gets faster'

The McLaren F1 LM has been developed as a direct result of the outstanding success which the F1 GTR has enjoyed, in both the 24 hours of Le Mans and the Global GT Endurance Series, during its inaugural 1995 racing season.

It is not a race replica but follows the specification of the Le Mans winning F1 GTR. Consequently the chassis, engine and transmission are virtually identical, being modified only enough to make them road usable. The most significant difference between the F1 LM and the F1 GTR is the acceleration, which will be substantially greater in the LM. This is possible owing to the fact that the LM is some 60kg lighter than the racing car, and the engine is not limited by the inlet air restrictors.

Race regulations restrict the air intakes on the F1 GTR to 2 x 39.4mm diameter, which results in 636 bhp and a top speed of 215mph. It is estimated that without these inhibitions the F1 LM will reach 668 bhp with a top speed of 225mph/360kph in high downforce configuration. The torque figures for the LM are 520 lb/ft or 705 Nm at 4,500 rpm. The estimated the 0-60mph figure will be under 3 seconds, with 0-100mph thought to be just under 5 seconds.

McLaren Cars Ltd are lucky enough to enjoy a rich and colourful motor racing heritage, not only with Formula One, but from the days when Bruce McLaren, campaigned his cars at Le Mans and in the Can-Am series. The F1 GTR's recent racing victories are reminiscent of the five Can-Am championships which were won between 1967 and 1971 and Bruce's own victory at Le Mans in 1966 in a Ford Mark II.

It has always been a dream to produce the 'ultimate road-going sports car' and this is something which McLaren Cars achieved initially with the McLaren F1 road car. As a mark of respect of for Bruce McLaren the LM, which represents a genuine race car experience on the road, has been painted vibrant orange which was extensively used when Bruce achieved his successes.

The company's aim has always been to develop and manufacture cars best in their class by design. The McLaren F1 LM is a celebration of that achievement so aplty displayed by the historic win at the 24 Heures Du Mans 1995.

There you are folks, I hope you enjoy all that.

EDIT: as it turns out the comparison part of the press release doesn't look quite that good now that I've posted it, please let me know if you want a .doc file that looks a lot neater in comparison.

[hurstg01]

some nice pics there, cheers - especially the 'fresh scan'...

[Le Man]

Ace pics Sauc3,

You have six pages missing from your LM press kit and two pages of Ron Dennis,s opening speach!!

[jayfive]

Some of that press release is optomistic, sub 5 second 0-100 hmmm very optimistic. 1.2 second quicker than a standard f1 to 100 i dont think so.

[amanichen]

Those photos are particularly nice because they show the little nuances and details which normally get glossed over.

[McLaren F1 Guy]

Sweet closeup shots of #016!
