Eight Smart roadster-coupÃ©s with higher power and higher torque engines took part in the celebration rally to mark ’100 years of the Solitude race’ (25 - 27 July 2003). Two standard three-cylinder engines have been joined to create a v6 bi-turbo with 1,396 cc engine capacity, power output of 170 bhp and torque of 162 lbs-ft.
The prototypes are proof of the achievement potential and versatility of the production car concept. The bi-turbo engines serve to demonstrate the technology and underline the sporty handling performance of the Smart roadster and roadster-coupé. The cars entered in the Solitude rally had a power/weight ratio of just 4.9 kilogrammes per bhp, accelerate from 0 - 60 mph in less than 6 seconds and reach a top speed of more than 136 miles per hour.
