McLaren F1 LM

 |
In honor of Mclaren's achievements at Le Mans, they announced the building of the McLaren F1 LM (LM for Le Mans).
Since five F1 GTRs had finished Le Mans, five F1 LMs would be built. The weight was reduced by approximately 60 kg (132 lb)
over that of the road car through the removal of various pieces of trim and use of optional equipment. The car also had a
different transaxle, various aerodynamic modifications (including a rear spoiler) and specially-designed 18 inch (457 mm)
wheels. The LM also used the GTR's upgraded engine without race-mandated restrictors to produce 691 PS (680 hp/508 kW).
Three of the five LMs that were made are easily recognized by their colour as they were painted "Papaya Orange"
as a tribute to the memory of Bruce McLaren, who had used the same colour for all his contemporary Formula One and Can Am
cars. LM1 and LM4, which were built for the Sultan of Brunei, have a black paintjob with blue yellow and gray stripes.
There are no known pictures of these vehicles, though there is one illustration drawn by a designer who has seen the
vehicles in person.
An F1 LM was used by CAR Magazine when they broke the world record for 0-100mph, achieving 5.9 seconds total time.
The car also reached a record by doing the 0-100-0 mph in 11.5 seconds being driven by racing driver Andy Wallace.
This record has since been broken by the Ultima GTR. The top speed of the LM is not as high as that of the F1 roadcar,
mainly due to the drag created by the rear wing, shorter gear ratios and a more blunt front end borrowed from the F1 GTR
which is meant to create more downforce. The top speed of the LM is quoted at 225 mph by McLaren Cars Ltd, but this has
not been proven nor tested. The car accelerating for 0-60mph is under 3.0 seconds.
Although only five F1 LMs were sold, a sixth chassis exists in the form of XPLM, the prototype for modifications to the
existing F1 to form the new F1 LM. This car is also painted Papaya Orange, and is retained by McLaren.
