Rumor that the next Subara WRX STI may get a diesel version, which is due in 2012. Subaru has been touting the idea a few years ago, and now it re-emerges again. According to Autocar, the new 2.0-liter diesel engine will likely generate more than 200 horsepower at about 300 lb-feet of torque. But we know all too well, it will likely get a turbo-diesel engine instead, and that will boost power to around 250-hp range.
Insider source says a smaller 1.5-liter four-cylinder gasoline engine base-model Impreza is also under consideration. Of course, if there will be such a diesel Subaru WRX STI, it will less likely make to the States; much like the Ford Fiesta diesel in Europe.
