To commemorate Ferrari’s 16th victory in the Formula 1 Constructor’s World Championship in 2008, Ferrari unveiled the Scuderia Spider 16M at World Finals in Mugello. It is a convertible version of the 430 Scuderia., The engine produces 510 PS (375 kW; 503 hp) at 8500 rpm and 470 N·m (350 lb·ft) torque at 5250 rpm. The car has a dry weight of 1,340 kg (2,954 lb) (80 kg lighter than the F430 Spider) and a curb weight of 1,440 kg (3,175 lb). The chassis was stiffened to cope with the extra performance available and the car featured many carbon fibre parts as standard. Specially lightened front and rear bumpers (compared to the 430 Scuderia) were a further sign of the efforts Ferrari was putting into this convertible track car for the road. Unique 5-spoke forged wheels were produced for the 16M’s launch and helped to considerably reduce unsprung weight with larger front brakes and callipers added for extra stopping power (also featured on 430 Scuderia). It accelerates from 0-100 km/h (62 mph) in 3.7 seconds, with a top speed of 315 km/h (196 mph)., 499 vehicles were released beginning early 2009 and all were pre-sold to select clients.
