A Prius hybrid powertrain into a Toyota MR2 chassis sounds like a no-brainer.
This is the TE-S800, and it represents what one Toyota engineer imagines an MR2 successor could be. It weighs approx 1,000 kg and with the 1.5 liter Otto-cycle 1NZ-FE engine outputting more than 115 hp at 6400 rpm plus the plug-in Prius’ 102 hp electric motor coupled to a Toyota E-CVT transmission, the TE-800 does 0-100 km/h in just 5.8 seconds.
The MR2 plug-in hybrid was one of several cars unveiled at the Tokyo Auto Salon by the Toyota Engineering Society which is a volunteer collective that mostly comprises Toyota engineers.
