As promised, BMW has released details regarding the four-cylinder variants that will make up the majority of the new Z4 roadster’s range.


The inline-six Z4 M40i was revealed back at Pebble Beach in August – read that article here.

The entry-level Z4 is the sDrive20i. Under the bonnet is a 2.0-litre turbocharged four-cylinder petrol engine producing 145kW (195hp) of power and 320Nm (236 lb-ft) of torque. Drive is sent to the rear wheels through a ZF eight-speed automatic transmission – it can do the zero to 100km/h sprint in 6.6 seconds. Above the 20i is the sDrive30i, powered by a 2.0-litre turbo-petrol four-cylinder that produces 190kW (255hp) of power and 400Nm (295 lb-ft) of torque. It drives the rear axle through the same ZF auto, and the 0-100km/h time has dropped to 5.4 seconds.


The M40i’s limited-slip differential, M Sport performance brakes and other standard performance goodies are available as options on the sDrive30i. 18-inch wheels are standard on the 20i and 30i, with the six-cylinder M40i getting 19 inchers.

BMW has also divulged some other technical details. The Z4’s electrically-operated soft-top roof takes 10 seconds to open or close, at speeds of up to 50km/h. No matter whether the roof is open or closed, boot space is listed at 281 litres – that’s over 50 per cent larger than its predecessor.

The full BMW Z4 range will make its public debut at the 2018 Paris motor show.
