BMW is to offer a new entry level version of its Z4 sports car next year, the Z4sDrive18i.
The car is powered by a detuned version of the current 184hp 2.0 petrol engine, outputting 156hp and slowing the 100km/h sprint by a second to 7.9.
Some minor detail changes to the lights of the 2-seater have been made for 2013.
