According to a recent report, the BMW Z4 successor will be a radical departure from its predecessor.

Set to be launched in 2017, the model will reportedly adopt the Z5 moniker and be based on the jointly-developed BMW and Toyota sports car platform. While the Automobile Magazine only says the model will ride on the joint architecture, sister publication Motor Trend says it will use a carbon fiber tub similar to the i3 and i8. Both also suggest the car could eschew its retractable hardtop for a more conventional soft top.

Power will reportedly be provided by a turbocharged 2.0-liter four-cylinder engine that has outputs of 190 bhp (141 kW), 245 bhp (182 kW) and 270 bhp (201 kW). There's also word of a high-performance Z5 M which could use a turbocharged six-cylinder engine with roughly 425 bhp (317 kW).
