The car is a regular 1998 McLaren F1, chassis #073 and it started out life as one of the 72 regular F1 road cars.
However, the mysterious ownerr of this particular F1 commissioned the McLaren factory to upgrade the car to LM specifications. This makes the car unique in a way that it has the mechanical upgrades of the LM cars together with the comforts of the regular F1.
The 6.1-liter V-12 engine fitted to the LM cars, was in included in this conversion, kicking out as high as 691 horsepower, matching the output of the legendary F1 GTRs that raced and won overall at the 1995 24 Hours of Le Mans. Together with the extra power, weight was dropped by approximately 59 kg (130 pounds), and extra cooling and downforce producing aero was installed. The 0-100 km/h (0-60 mph) time is less than 4.0 seconds, and the extra downforce meant the top speed was lowered to approximately 362 km/h (225 mph) from 386 km/h (240) mph for the regular F1.
This particular car was sold at an auction in Monterey two years ago for a staggering $13.75 million. I wonder, how much is worth today?
