McLaren MP4/20

The McLaren MP4-20 of 2005 stood out for its speed and fragility. In a year with tougher regulations —engine for two weekends and prohibition of changing tires in race—, McLaren presented a new chassis with a flat nose, short wheelbase and the "horn wings" behind the intake. Its Mercedes-Ilmor FO110R V10 engine, together with the Michelin tires, made it the fastest car of the year. Designed by Adrian Newey, Mike Coughlan and Peter Prodromou, the MP4-20 won 10 races (7 with Räikkönen and 3 with Montoya) and added 7 poles, but its reliability betrayed it. Renault won by consistency, leaving McLaren second. Nevertheless, the MP4-20 is remembered as the fastest car of 2005 and a masterpiece of modern aerodynamics.
