The BMW X5 has been announced as the successor to the popular roadster chassis, with the company announcing that it will now offer a new chassis design that uses aluminium and steel instead of aluminium and carbon fiber.
The BMW Z4 will be offered in the S550 version and S550L version, while the BMW M3 will be available in the Z3, Z4 and Z4S.
The new chassis will have a maximum output of 350hp (217kW), and the rear wheels are made from aluminium alloy.
The S550 will be the first new BMW car since the S400 in 2011, while all the other BMW X models will be rebranded to M, M3 and M5.
It is not clear if the new aluminium X5 will also be available with a 2.0-litre turbocharged V6 engine.
The car is due to arrive on the market in 2018, and the BMW Z5 will be launched in 2020.
