# BMW Z4 (G29)

The BMW Z4 (G29) is a two-door roadster produced by German automobile manufacturer BMW. It was introduced in 2018 as a successor to the E89 Z4. As a fifth model in the lineage, the Z4 (G29) marks the return of the soft-top roof to the Z Series sports cars.

## Development and launch

The G29 Z4 was introduced at the Pebble Beach Concours d’Elegance on August 23, 2018.
Designed by Australian born Calvin Luk, the car is based on the Z4 Concept unveiled a year earlier, and was developed alongside the fifth-generation Toyota Supra due to BMW's partnership with Toyota. The design was inspired by the Z8. The G29 Z4 is based on the Toyota-BMW joint sports car architecture which also underpins the fifth-generation Supra 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 (G29) instead of a retractable hardtop of its predecessor. 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). It uses a multi-link rear suspension.
The official launch of the G29 Z4 took place at the 2018 Paris Motor Show in October. The car was available for sale in March 2019.
On March 11, 2022, Magna Steyr halted production of the BMW Z4 (along with the 5-Series) for two weeks due to the lack of components caused by the 2022 Russian invasion of Ukraine.
The LCI model was introduced in September 2022. The M Sport appearance package became standard across the range, although with several changes.
* Z4 sDrive20i (South Korea) with standard appearance package
* Z4 sDrive20i (South Korea) with standard appearance package
* Z4 sDrive30i(Canada, pre-facelift) with M Sport appearance package

The car is available with BMW ConnectedDrive 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.
