A roadster designed the way only BMW can: the classic proportions of the stretched bonnet and short overhangs are complimented by the low seats near to the rear axle to grant the driver a perfect feel for the road. The modern shape, an interplay of striking contours and soft mergers, fully captures the character of this vehicle from its characteristic kidney grille to the powerful wheelarches at the rear. However, it's the way this roadster effortlessly negotiates straights and bends that makes it truly like no other.

And in the BMW Z4 sDrive35i and sDrive35is, High Precision Injection and a BMW Twin Power Turbo dual charger help release up to 225 kW (306 hp) on command.
