The 2019 BMW Z4 has been revealed in patent images which show every angle of the car's styling, revealing a look that remains true to that of the concept.
The upcoming Z4 model, which is expected to go on sale in March 2019, has been caught on camera testing for more than a year. The latest sighting showed the car wearing production-spec bodywork covered by light camouflage. It sits on smaller-diameter wheels than earlier spotted cars, suggesting it's a lower-spec model.
An earlier video (see below) showed the car cornering at pace. It was also wearing winglets on its nose, suggesting that BMW was assessing the car's performance when under load.
Powering the new Z4 will be a choice of BMW's latest turbocharged petrol engines. The Z4 sDrive30i will get a turbocharged 2.0-litre four-cylinder that produces about 248bhp, while more powerful variants will get a turbocharged 3.0-litre six-cylinder unit that's shared with the M240i, producing about 350bhp.
Both engines will come with standard rear-wheel drive and a ZF eight-speed automatic gearbox.
The Z4 shares parts with the upcoming Toyota Supra and is similarly expected to be offered with a hybrid drivetrain. Such a drivetrain would likely come with four-wheel drive.
BMW's decision to equip the Z4 with the same rear axle as the M3 and M4 suggests its hardware will be compatible with the 425bhp twin-turbo 3.0-litre straight six-engine of those models or the 365bhp turbocharged 3.0-litre six-cylinder powerplant from the M2, along with a seven-speed dual-clutch automatic gearbox.
This car would be badged as an M model and therefore will get bespoke bodywork and a more focused chassis set-up.
Inspiration for the new Supra's design has been taken from the striking FT-1 concept, first seen at the Detroit motor show in 2014.
