The whisperings indicate that project will spawn both a replacement for the BMW Z4 and a long-awaited Toyota Supra successor based on the FT-1 Concept shown above. Word is that the new cars will feature front-engine, all-wheel-drive layouts with plug-in hybrid technology. This news would appear to run somewhat counter to earlier reports that BMW and Toyota are teaming for a six-figure hybrid supercar . According to Autocar , the project will benefit from the experience Toyota gained with the TS030 , its hybridized Le Mans prototype. The evidence for this is, of all things, a Toyota Yaris – in particular, the Yaris Hybrid R that was shown at the 2013 Frankfurt Motor Show last September. That car used a 300-horsepower, 1.6-liter gas engine, while a pair of 60-horsepower electric motors provided all-wheel-drive push (an additional motor also sent additional juice to the front axle). The 414-system-horsepower drivetrain used supercapacitors in place of the traditional lithium-ion batteries of traditional hybrids. For the production sports cars , Autocar claims that the Yaris Hybrid R’s setup will serve as the basis for the new powertrain, although it won’t be a direct carryover. Instead, a 2.0-liter BMW engine will be paired with Toyota-designed, BMW-built motors.
