The Prototype seen here previews the 10th generation version of the Civic Si, which will go on sale next year in the States as both a sedan and a coupe.
The Civic Si Prototype is fitted with an extensive body kit that includes front and rear splitters, a rear spoiler, and a trapezoidal exhaust tip cover.
Honda says that the new car will be the most powerful yet to wear the Si badge, with power coming from the company's new 1.5-litre direct-injection turbocharged four-cylinder engine. The motor drives the front wheels via a short-shifting six-speed manual transmission.
The company is staying quiet about the Si's key numbers, so engine output may not be that different to the 134kW/240Nm version offered in the regular Civic range Stateside.
Regardless of whether the Si gets a power and torque hike, it should have significantly less than the 231kW/400Nm available in the ninth-generation Civic Type R hatch.
The Si Prototype rides on 10-spoke 19-inch alloy wheels fitted with 235/35 tyres, and the production vehicle will be fitted with active damper and steering systems, as well as a limited-slip differential.
On the inside, the Si Prototype features red stitching on the door trims, steering wheel and shifter boot, as well aluminium pedals and shift knob, red instrument and audio system lighting, and carbon-fibre-like trim. More importantly, the car is fitted with grippier sports seats.
We're waiting to hear back from Honda Australia about potential local availability.
