The 2021 BMW Z4 is the third generation of BMW's reinvented roadster. Powered by a sharp-handling rear-wheel drive system, the Z4 provides two strong engine options. The base sDrive30i models host a 2.0-litre 4-cylinder turbocharged engine producing 255 horsepower, whilst the sportier sDrive M40i variant boasts a 3.0-litre 6-cylinder engine producing a potent 382 horsepower. Both engine options come with an 8-speed automatic transmission. The 2021 variant has two trims: sDrive30i and sDrive M40i. A range of hi-tech equipment come inclusive such as a 10.25-inch touchscreen with Apple CarPlay and Android Auto, advanced safety aids like automatic emergency braking and lane-departure warning amongst others. Notable changes for 2021 include the discontinuation of the track-focused M40i's standard adaptive suspension.
