Toyota recently introduced a turbocharged 1.2-liter four-cylinder engine in versions of the Scion iM hatchback sold overseas. The engine, which features an undersquare design, also comes with direct fuel injection and variable valve timing to help maximize output while minimizing fuel consumption and at present delivers 114 horsepower and 136 pound-feet of torque.

According to Motoring, this is the engine that will power the production version of the S-FR sports car concept unveiled at the recent Tokyo Motor Show. The Australian publication cites comments made by an anonymous senior powertrain engineer at Toyota.

We should note that it’s also been reported that the production version of the S-FR will come with a naturally aspirated 1.5-liter four-cylinder engine delivering approximately 130 hp and almost 110 lb-ft. With either engine, performance should be spritely as the car is expected to weigh in at less than 2,200 lbs.

The production version of the S-FR will sit at the bottom of a three-tier sports car lineup at Toyota, with the GT 86 (a Scion FR-S for American readers) sitting in the middle and a new hybrid sports car co-developed with BMW sitting at the top. This range-topping model is expected to revive the Supra name.

Unfortunately, there’s been no mention of when Toyota’s additional sports cars will be launched, though both are expected before the decade is out.
