Last time we had a look at the new Legacy we were driving the flagship 3.6 R model that is more about riding around in relaxed comfort whereas the Azurite Blue Pearl 2.5 GT model is what the Japanese automaker refers to as their sporting Legacy. The biggest difference between the two cars is their power train, while the R was powered by a 3.6 Liter flat six cylinder engine that made 256 HP and 247 lb-ft of torque and is connected to a five speed automatic transmission which of course fed Subaru’s Symmetrical All Wheel Drive System. Our new 2010 Legacy 2.5 GT uses Subaru’s familiar 2.5 Liter turbocharged flat four making 265 HP and 258 lb-ft of torque and is shifted with a six speed manual gearbox, the combination is good for a 0 to 60 MPH time of 5.9 seconds. Despite the smaller displacement and being down two cylinders, the addition of a turbocharger more than makes up for the difference while taking a few pounds off the front axle at the same time.
