Find out about the platform behind the Toyobaru, now on display in Geneva, inside.

While the Toyota FT-86 II Concept car is on display at the Toyota stand in Geneva, the platform the car is built upon is featured at the Subaru stand.  The Subaru BOXER Sports Car Architecture, along with the rear-wheel drive concept vehicle, were jointly designed by both automakers.

While the vehicle's exterior design is 100% Toyota, the underpinnings are pretty much entirely Subaru, right down to the 2.0-liter naturally-aspirated horizontally-opposed Boxer engine mounted near the front.  The fact that the engine sends power to the rear wheels, instead of all four, clearly comes from the Toyota side of the table.

Subaru acknowledges that the engine could be produced from aluminum to lighten the weight.  Compared to Subaru AWD vehicles, the company says, "the engine now sits even lower and further back in the engine bay."  This results in better balance, solid handling and a lower center of gravity.

The production car is expected to begin assembly in Spring 2012.  You can read more about the Toyota-branded concept here at WCF.
