BMW’s roadster is definitely not a sales leader, but it ranks up there as one of the most captivating, for sure. The Z4 is available with a four- or six-cylinder engine, with output ranging from 255 horsepower (sDrive30i) to 382 horsepower (M40i). As a result of a partnership with Toyota, it shares its mechanical components with the GR Supra. In case you’re wondering about cargo capacity, the Z4’s trunk can fit 281 litres.
