The McLaren F1 was so advanced in terms of performance that it redefined the meaning of the term ‘supercar’. But there’s always something faster and during its production run, there was a faster variant, limited in production but now up for sale from a private collection in Japan.

Built for racing, the F1 GTR competed in the BPR Global GT Series, known now as the FIA GT Championship. The exclusive car’s production run lasted three years from 1995-1997, with 9 built the first two years and ten the final year. In 1997, the car weighed around 910kg and generated a conservative 600hp (447kW) from its de-stroked 6.0L version of the F1′s 60-degree V12.

The example now on sale at Bingosports in Tokyo, Japan claims to be chassis #28R, the very last of the cars built. Chassis #28R was originally #27R, but was damaged and rebuilt into a spare car that later raced at the back end of the inaugural season of the FIA GT Championship. Little else is known about the car or the sale, aside from its Gulf Oil livery and its distinctive ‘Longtail’ rear wing section, a change in the aerodynamics for 1997 designed to get more grip over the rear wheels.

A standard road-going McLaren F1 recently went for $4 million at auction, and it’s possible that this racing example could fetch even more. Check out some great images of the F1 GTR in the gallery below.
