It's called the Hybrid-R, and it's landing at Frankfurt very soon. Obviously, Toyota's being very cheeky with the details – including that shady teaser pic – but the essence of it sounds very exciting. We're told it's based on a "current Toyota production model", featuring a powertrain setup similar to the TS030 hybrid racer used at La Sarthe.
As such, it's got over 400bhp from a "high-power internal combustion engine" connected to a pair of electric motors with a super-capacitor that stores energy from braking. There are also two different driving modes available for this Hybrid-R concept – road and track.
It's that last little nugget that gives us hope; hope that Toyota will do the decent thing and base it on the GT86, make it sound like a one-tonne light-sabre being switched on, and put it into production very soon. Unfortunately, the front of this teaser pic doesn't look anything like a GT86. It looks like a Yaris. Or an Auris.
Naturally, we'll have full details when it's revealed on 10 September at the Frankfurt motor show, so you'll have to keep the guessing games going until then.
