Subaru STI: Is Diesel the Intersection of Power and Fuel Economy?

car_photo6.jpgWe all know that fast cars are fun and fuel-sipping cars are environmentally responsible, but is there a middle ground?

Short of expensive electric sports cars like the Tesla Roadster, there may be a solution to be found in diesel. Not only can diesel cars be fueled with waste vegetable oil, biodiesel, or some mixture of these fuels, but diesel engines produce a lot of torque and get better fuel economy than their gasoline-powered brethren.

Autoexpress reports that the Impreza lineup will soon feature a 2.0L diesel engine sporting 148 bhp - but that engine could easily be tuned up to 180bhp for use in a sportier WRX model. This model could go 0-60 in under 7 seconds and wouldn’t top out until a respectable 140 mph.

Certainly impressive, but what we really care about is the fact that this engine could achieve up to 45mpg and reduce CO2 emissions 40% compared to the gasoline-powered STI.
