Subaru has announced its partnership with Cosworth for the development of a new 1.6-liter boxer four-cylinder turbo engine. Italian magazine Autosprint reports that the new engine will be launched in 2012 when Subaru will bring out the new generationImpreza .
Next to the Impreza, the new engine will mainly serve for the mass return to the Japanese competitions. With the new FIA rules in place, the engine is necessary for the WTCC rally.
Subaru and Cosworth’s newly developed relationship has recently produced the Impreza STI CS400 , a model that delivers a total of 395 hp at 5750rpm and makes the 0 to 60 mph sprint in 3.7 seconds. This was an impressive task compared to the standard Impreza WRX STI at 300PS / 296bhp at 6,000rpm with a 5.2 second sprint. It is limited to only 75 units, each priced at $72,000.
The current Impreza is offered in four distinct output levels: 2.5i 170 hp; 2.5GT 224 hp; WRX 265 hp, and STI 305 hp.
