by Brian Byrne. BMW has added a new four-cylinder derivative to the Z4 line-up — the same 1,995cc unit featured in the BMW 1 Series and the latest BMW 320i Saloon.
The engine produces 150bhp and pulls 200Nm of torque. The unit is built at BMW's Hams Hall engine facility in Warwickshire and is EU4 compliant.
It offers significant power and torque increases over BMW's previous four-cylinder petrol unit, by improving the intake and exhaust systems and the provision of a new electronic control unit which provides a more instant throttle response.
Zero to 100 km/h now takes 8.2 seconds, virtually a second faster than the new BMW 320i.
