Details about the Cosworth Edition Subaru were disclosed during the auto show in Geneva. Info about the pricing and photos has also been going around the web prior to its official date of sale. Subaru insiders have revealed though that this version of the Impreza will not reach the US soil.

According to a report filed by Autocar, Cosworth tweaked the car’s flat-4 2.5L engine and fitted it with performance pistons, oil pump, head gasket, con rods, and bearings. Cosworth also reprogrammed the ECU, custom made the exhaust system, and upgraded the blower.

The changes made up the horsepower of the car to 395 horsepower and its torque to a good 398 pound-feet. Now the Impreza WRX STI can zoom from 0 to 60 mph in under 3.7 seconds. The top speed is electronically limited to 155 mph.

The suspension of the lowered car features the result of the collaboration between Cosworth and Bilsten & Eibach. The ride also gets AP Racign bespoke brakes with bigger front discs equipped with 6-piston calipers.

Some restyling was done giving the car a reworked front bumper, mesh grille, fog lamps, rear spoiler, and 18-inch alloy wheels. Buyers can get this Impreza in red, silver, and dark gray. The insides feature sport buckets from Recaro, tinted glass, and center console in black piano.

The A-Line concept is based on the WRX STI Impreza. It was built to provide supreme performance to a wide scale of customers by incorporating the 2.5-liter turbocharged Boxer engine unit and SPORTSHIFT enhanced 5 Speed Automatic Transmission. Aside from that, the latest WRX STI was refined to provide a more comfortable and secured driving experience such as the power-adjusted front seats.

The Boxer engine is featured with a single scroll turbocharger and can produce a varied amount of torque, from a low, to middle, to high revved range. The Subaru also provided WRX STI A-Line with Dual Active Valve System (AVCS) which is to aid the valve timing on both the intake and exhaustion of the valves, thus improving the torque range and its emissions. Also found in the engine is the Tumble Generation Valve (TGV) which facilitates air stream to produce a high level of combustion.

Subaru Impreza WRX STI A-Line is also available in a new color, “Satin White Pearl”. The car manufacturer stated that there are no plans yet of bringing the model in the US automotive market. At present, the 2.5 GT Impreza is the fastest automatic Subaru in US that produces 224 horsepower.
