Specifications of the exciting Toyota S-FR concept have yet to be officially released, but it appears the juicy details regarding the production entry-level rear-wheel drive sports car are already out in the open, if S-FR Forums has got this one correct.

It seems that Toyota engineers have taken a page out of the Mazda MX-5 handbook, such are its similarities – and it starts with what’s under the bonnet. Powering the S-FR will reportedly be a 1.5 litre naturally-aspirated engine – essentially the JDM Corolla Axio‘s Atkinson-cycle 2NR-FKE with D-4S direct injection and redesigned ports (it also shares its roots with the Avanza’s new 1.5 litre Dual VVT-i mill).

Output is rated at 130 PS and 148 Nm – that’s 1 PS and 2 Nm down on the JDM MX-5‘s 1.5L SkyActiv-G engine, but the S-FR should more than make up its deficit by being 10 kg lighter at 980 kg. What’s more, unlike the Mazda, the Toyota is slated to only come with a six-speed manual gearbox – there’ll be no auto option, not even if you wanted to. Fuel consumption is quoted at 20 km per litre on Japan’s JC08 test cycle.

Dimensions have also been given – surprisingly, despite the compact proportions, the S-FR is set to be slightly bigger than the MX-5, measuring 3,990 mm long (75 mm longer), 1,695 mm wide (35 mm narrower) and 1,320 mm tall (85 mm taller), with a 2,480 mm wheelbase (165 mm longer). Then again, the S-FR is a 2+2, whereas the MX-5 is a strict two-seater.

Other details include a suspension setup consisting of MacPherson struts at the front and double wishbones at the rear. Indicative pricing has also been bandied about, with the S-FR set to cost 1.5 million yen (RM52k), considerably undercutting the 2,494,800 yen (RM86,500) base model MX-5.
