E89 Z4

BMW's sporty convertible received a mild update in August 2013, to help compete against higher-volume sellers like the Mercedes-Benz SLK and Audi TT.

All three variants received extra equipment, with the two entry-level variants receiving an eight-speed automatic as standard over the previously offered six-speed manual transmission.

New standard features included 3D satellite navigation, a high-res 8.8-inch dashtop display, internet connectivity, and a revised music smartphone music interface and voice control system.

This new spec came in addition to existing equipment such as a rollover protection system, 17-inch alloy wheels with run-flat tyres, heated side mirrors, cruise control with auto braking, front and rear parking sensors, bi-xenon headlights with LED daytime runners, an auto-dimming rear view mirror, rain-sensing wipers, heated leather seats, dual-zone climate control and Bluetooth with audio.

The M Sport Package was available on both four-cylinder variants (it was already standard on the six-cylinder) and includes 18-inch light alloy wheels, aluminium interior trim around the vents and dials, a dark BMW Individual roofliner, sport seats, M leather steering wheel, M sport suspension and a specially designed aerodynamics package.
