Cosworth is back tweaking high-performance road cars and details and photos of it’s latest offering have just been released. Named the Cosworth Impreza STi CS400 the car is a result of a joint effort between Subaru and Cosworth. The vehicle is based on a stock Subaru STi hatch which usually generates 304 bhp (227 kW) but Cosworth has given it a thorough working over.
Visually the special STi has a new front bumper, mesh grille, foglights and a replacement rear spoiler. Filling the guards are a set of crisp 18-inch alloys. Exterior paintwork comes in three choices – silver, dark grey or red. The interior features new Recaro buckets, a piano black centre console and tinted glass.
Maximum power from the 2.5-litre turbo mill has been boosted up to 395 bhp (295 kW) while torque has been increased to 540Nm (398 lb-ft). The 0 – 100 kph time is now a supercar matching 3.7 seconds and top speed is a limited 250km/h.
The Cosworth engine upgrades include new pistons, connecting rods, a redesigned head gasket and a new turbo with a new compressor design and wastegate actuator. To get the most from the reworked engine the vehicle’s ECU was tweaked as well.
Suspension has been lowered by 10mm while the front brakes featuring AP Racing discs measuring 355mm. The track is widened by 12mm.
It’s set to be an exclusive ride with only 75 units of the Cosworth Impreza STi CS400 being built exclusively for the UK market. Pricing starts at £49,995 ($107,500 NZ)
