The setup will improve fuel economy, boost torque and lower cold-start emissions. The GDI system on the Solstice GXP comes on a turbocharged Ecotec 2.0-liter, four-cylinder engine, according to AutoTech Daily. It will produce 260 horsepower and 260 pound-feet of torque, with the highest specific output for any GM engine ever: 2.1 horsepower per cubic inch of displacement. Buyers will have the choice of a standard five-speed manual gearbox or an optional five-speed automatic.
The upcoming and highly anticipated Pontiac Solstice GXP will feature General Motors’ first North American application of a gasoline direct-injection or GDI system, a report says.
