BMW Z4-S

This range topper sharpens the roadster's sporting pedigree by offering an even higher level of performance and adds to its sleek, sporty looks with some extra styling touches. It will premiere at the Detroit motor show this month.  The 3.0-litre six-cylinder engine with its twin turbocharger technology and high precision direct injection increases maximum torque to 450Nm with an extra 50Nm of torque available in the upper gears for extra power when overtaking. This is achieved by an extra short time boost in turbo pressure. Zero to 100km/h is reached in around 4.6 seconds.
