Seven-times F1 world champion Michael Schumacher helped launch Ferrari's new 430 Scuderia at the Frankfurt Motor Show.
The retired race was involved in the development and road testing of the F430 derivative, giving advice on traction control, steering and the transmission to the car's engineering team.
"Part of my new role within Ferrari, is road car testing. I've had to go to several race tracks to test the new car," the German told a news conference.
Ferrari has launched the 430 Scuderia as a special series model using technology derived from its F1 involvement.
Based on the F430, the car is essentially a track day car for the well-heeled and features a new traction control system using Ferrari's E-Diff electronic differential and the F1-trac traction and stability control systems for the first time in one car.
A large part of the 430 Scuderia's development was invested in shedding weight and the car is about 90 kg lighter than the regular F430.
Standard seats and carpets, the audio system and rear windscreen have been stripped out and lightweight bucket seats, a plexiglass rear screen and naked floor panels are the result.
Powered by a 4.3-litre V8 producing 380 kW at 8 500 r/min, the F1-style paddleshift transmission reduces gearchanges to 60 milliseconds. This should allow 0-100 km/h in about 3.6 seconds and a top speed of 322 km/h.
