A test mule has been spotted running around Toyota's test track in Toyota City, built off a shortened Subaru Legacy chassis and powered by the firm's SOHC two-liter flat-four. Although the mule's underpinnings are currently derived from the Legacy's (with about 200mm lopped off), it's expected that a version of the Impreza 15S's platform will be used instead. This gives credence to the idea that the new coupe will send power to the rear wheels, as the AWD chassis could be modified to be exclusively RWD. Currently, the test car is running the all-wheel driveline with the front drive shafts removed.
Subaru's 108 HP 1.5-liter boxer (EL15) is likely to be used to power the new coupe, apparently due to the rear differential's fragility and Toyota's aim of making the coupe as fuel efficient as possible. While barely cresting the 100 HP mark won't set the spec sheet ablaze, the fact that the vehicle will tip the scales at 1,100 kg (2,425 lbs.) should make it a competent performer in the same way as its AE86 forbearer.
If Toyota can keep the weight down (a constant challenge), while keeping the price below 2,000,000 yen, it's rumored that we could see the coupe make its debut sometime next year, with sales beginning later in 2008.
