The Toyota GT86 (Scion FR-S) is one of the most enjoyable vehicles that enthusiasts can actually afford to own. However, Toyota realizes that the Mazda MX-5 Miata is in a class of its own in the compact sports car segment and is planning a competitor that will be smaller than the FR-S but just as enjoyable. We've already know what the S-FR looks like thanks to a concept at the Tokyo Motor Show, but the most important aspect of the sports car was a mystery, until now.

According to a report by Motoring, the compact S-FR Coupe is expected to get a turbocharged 1.2-liter four-cylinder engine from the Scion iM hatchback that's sold overseas. The motor will have direct fuel injection and variable valve timing for maximum output while returning good fuel economy. At the moment, performance is expected to be at 114 hp and 136 lb-ft of torque, which is less than the rumored 130 hp. However, with an expected weight of less than 2,200 lbs., a smaller engine may provide enthusiasts with the same thrilling ride as the FR-S. The Miata's 2.0-liter four-cylinder engine makes 155 hp and weighs in at 2,332 lbs, which is more than the S-FR's expected engine.
