The BMW Z4 3rd generation is a two-door roadster produced by BMW. It was introduced in 2018 as a successor to the BMW Z4 2nd generation (E89). The Z4 third generation marks the return of the soft-top roof as opposed to its predecessor. The Z4 third generation (G29) was introduced at the Pebble Beach Concours d'Elegance on August 23, 2018. It is based on the Z4 Concept unveiled a year earlier, and was developed alongside the fifth generation of the Toyota Supra due to BMW's partnership with Toyota. It is based on the Cluster Architecture platform and has a 50:50 weight distribution with weight savings of up to 50 kg (110 lb) as compared to its predecessor. The soft-top convertible roof returned on the Z4 3rd generation instead of a retractable hardtop. The roof can be raised or lowered in 10 seconds at speeds of up to 50 km/h (31 mph). The boot is 50% larger than that of its predecessor and has a capacity of 281 litres (9.9 cu ft). The official launch of the Z4 3rd generation took place at the 2018 Paris Motor Show in October. The car is scheduled for market launch in March 2019. As rear axle a multi-link suspension is used. The sDrive models are available in a Sport line or the M Sport package. Available driver assistance systems include active cruise control, lane change warning system, a parking assistant, and collision warning with braking intervention. The Z4 is offered with a 10.25-inch display with the iDrive 7.0. The car is available with BMW Connected Drive services which allow for over-the-air updates for the navigation maps and operating system. The digital key feature allows the car to be unlocked and started with a smartphone, and access can be shared with other people. It is also available with a customisable, digital instrument cluster (called BMW Live Cockpit Professional). The initial model is the M40i First Edition which has Frozen Orange metallic paintwork and Vernasca leather, 19-inch alloy wheels, adaptive dampers, a Harman Kardon surround sound system and a head-up display.
