According to Motor Trend, the next-generation BMW Z4 will ride on a modified version of the rear-wheel drive platform that underpins the Toyota GT86, Scion FR-S and Subaru BRZ. The updated GT86 architecture will also underpin Toyota's upcoming Supra sports car.
The Toyota Supra is tipped for a 2017 market launch, but the new BMW Z4 could launch sometime before that. The current version of the Z4 was introduced in 2009, so BMW will likely be eager to update the popular sports car well before the introduction of the Supra.
Toyota will reportedly show off a concept version of the new Supra later this year at the Tokyo Motor Show, so it remains possible that BMW could preview the next Z4 with a concept at this year's Frankfurt Motor Show.
