The 2006 Pontiac G6 Coupe is offered in two models, the GT and the GTP. The GT option gets you a 3.5-liter V6 with 201 horsepower, hooked to a four-speed automatic with manual shift capability. The sportier GTP adds a 3.9-liter V6 producing 240 horsepower, connected to either a six-speed manual or a four-speed manual-shift automatic. Though styling isn’t groundbreaking, the 2006 Pontiac G6 Coupe is an attractive contender in its class.
