The super-long bonnet extends into a steeply raked windscreen and an almost targa-like roof shape. There’s a pointy buttress extending above the cockpit, and the almost Porsche Carrera GT-alike rear end looks like it has a similar light structure to the Concept 8-series revealed at Villa d’Este in 2017.
BMW says it will be revealed very soon, which might be at the Pebble Beach Concours d’Elegance in California – where BMW has a history of revealing show cars.
It shares its technology with the next-generation Toyota Supra in a strategic partnership between both brands. BMW will have a convertible-only Z4, while the Supra will be sold only as a coupe, giving the two brands more clear water.
The production-ready Z4 will have a range of engines including a 2.0-litre turbocharged petrol engine producing 194bhp and 236lb ft of torque. A six-speed manual gearbox has been spotted in some spy pics, but we can expect to see BMW’s eight-speed auto, too. There may also be a Z4M version, likely to feature a turbocharged straight-six with around 450bhp.
If it makes it here, we can expect the Z4 to arrive our shores probably somewhere in a year or so.
