🏎️💨🎶😌👌🏻 Projects like this do not come twice.
In decades of significant and individualized customer commissions, this project stands apart without qualification as the most exclusive undertaking in our operation’s history to date.
Being trusted at a machine of such importance was a once-in-a-lifetime opportunity, not merely to observe or participate, but to actively provide meaningful input.

The McLaren MP4/3 was the car with which the McLaren team competed in the 1987 Formula One World Championship. It was also the last McLaren car to be powered by the TAG-Porsche turbo engine that had been introduced in 1983. The car was driven by double World Champion Alain Prost and Stefan Johansson.
The engine was the same 1.5 litre, Porsche built, TAG funded and badged twin-turbo V6 engine that had so successfully powered the MP4/2 since 1984, first F1 race car with electronic telemetry data recording. Slight changes were made to cope with the new reduced fuel tank limit of 195 liter and restricted turbo boost to 4.0 bar after turbo charging was unrestricted prior to 1987. The engine featured an updated Bosch Motronic 1.7 engine management system, produced 790 bhp (590 kW) in race trim and up to 850 bhp (630 kW) in qualifying at maximum 12.300 rpm.
The MP4/3 represented the pinnacle of the development of the McLaren TAG-Porsche partnership, a technical masterpiece of remarkable engineering. Its impressive legacy is unforgettable, captivating and embodying an era that many fans consider the golden age of motorsport.
