BMW Z4 G29

The G29 is the BMW Z4 generation our specification records cover for US model years 2019–2026. Across that run EPA certified 17 versions of it for sale in America, under 2 trim names. It was sold as a roadster.

Dimensions are the figures the panel above does not carry. The G29 measures 170.9 in · 4,341 mm long, sits on a wheelbase of 97.2 in · 2,469 mm and weighs 3,296 lb · 1,495 kg to 3,463 lb · 1,571 kg. Length and wheelbase come from Transport Canada, which measures every vehicle sold in North America; curb weight from the same source.

The generation did not stand still: the strongest version rose from 225 hp in 2019 to 382 hp in 2026. A G29 from the first model year and one from the last are not the same proposition, which is worth remembering when a listing gives only the chassis code.

Set against the E89 that preceded it, the G29 is 4.0 inches longer at the shortest version and 55 lb · 25 kg heavier at the lightest. Both figures are taken from the lightest and shortest version we hold for each, so they compare like with like rather than setting a base car against a loaded one.

Every version we hold under this code is rear-wheel drive. That matters on the used market more than it looks: which axles are driven changes the weight, the service list and the price, and the badge does not always say which you are looking at.

This archive holds 1 original US brochure covering the G29, with the text searchable. It is the source of the figures no government record collects — torque, acceleration and the equipment lists — and it is what BMW told American buyers at the time rather than what is said about the car now.

Gaps are left as gaps. We do not hold curb weight for 1 of the 17 and horsepower for 1, because Transport Canada does not publish a weight for every model and EPA began recording certified output usefully only in the late 1990s. A dash on this site means the figure is not in a source we can name, never that it is roughly the same as the row above.
