Design-wise the BMW Z4 styling has only had minor mid-life enhancements. The headlights now include white LED corona rings and a white ‘eyebrow’ with additional chrome detailing, while in profile the side gill features chrome detailing and LED side repeater lights. The roof that can be raised or lowered in 20 seconds at speeds of up to 32km/h is still a standard feature.
The big news is the inclusion of an entry-level Z4 to the range – the sDrive18i. This new derivative uses a detuned version of the existing 2.0-litre, four-cylinder, twin-scroll turbocharged engine. In 18i guise it produces 116kW and is capable of powering the Z4 to 100km/h in less than eight seconds. Not mind-blowingly fast, but enough for most people.
On the flipside, it is likely to be the most frugal Z4 in history. BMW claims 6.8 litres/100km and an emissions figure of just 159g/km.
Some of the existing engines have also received enhancements to improve their overall performance. The BMW Z4 sDrive20i comes with a 137kW engine that achieves 6.8 litres/100km and 159g/km CO2. The model is the most popular derivative of Z4 currently accounting for 80 percent of sales.
Further up the range and the four-cylinder twin-scroll turbocharged sDrive28i, and the six-cylinder twin-turbocharged sDrive35i and the sDrive35is offer customers greater performance courtesy of their respective 180kW, 230kW and 250kW power outputs. All cars are rated at an electronically-limited 250km/h top speed.
Transmitting the power to the road is a six-speed manual gearbox as standard. Customers can also specify an eight-speed automatic with gear shift paddles located on the steering wheel, while buyers of the BMW Z4 sDrive35is have a seven-speed Double Clutch Transmission, again with gear shift paddles, as standard.
