If a GTP badge is on the trunk, a bigger V6 is at work. In this case, it’s a 12-valve, 3.9-liter six-cylinder engine that also uses a cast iron block and aluminum heads but tosses variable-valve timing into the mix. The GTP packs a little more punch behind the accelerator than the base GT, to the tune of 227 horsepower at 6,000 rpm and 235 lb.-ft. of torque at 3,000 rpm, again, courtesy of low-grade petrol. With a four-speed automatic pushing power to the front wheels, fuel economy is expected to reach 18 mpg in the city and 26 mpg on the highway.
