BMW Z5 spyshots-03

The BMW Z5 has been spotted testing on the ice again. Said to be the successor to the Z4, the roadster here will reportedly be making its debut in 2017, before it officially goes on sale in the year 2018.

Developed together with Toyota, the two-seater is rumoured to be larger and more expensive than the Z4. The photos that were captured are similar to the previous ones which we saw earlier this year, but the (large) kidney grille is now taking shape from the looks of it.

It will reportedly be offered in two styles, the first is a soft-top version (as pictured here), while the other will be in the form of a hard-top coupe – similar to the first-gen Z4, which also had a coupe option. A few visual elements may be borrowed from the BMW 328 Homage and Vision Connected Drive concepts too.

Underneath, the Z5 will have the same underpinnings as the upcoming sports car from Toyota, which will apparently be the next-gen Supra. Both cars are said to be coming with the same rear-wheel drive platform.

As for power, the Z5 will likely be offered with a turbocharged 2.0 litre four-cylinder engine and a 3.0 litre six-cylinder mill, along with an M version, which may sport the M4’s 425 hp twin-turbo straight-six unit. BMW Blog asserts that an xDrive all-wheel drive option is also in the plans.
