Pontiac Grand Am GXP
Available in late spring 1998, the fifth-generation Grand Am shared its basic design with the Oldsmobile Alero (also new for 1999) and Chevrolet Malibu (introduced in 1997), but was slightly shorter and featured a longer wheelbase by more than three inches (76 mm). It featured a fully independent suspension set up, with a revised MacPherson-Strut on the front and a Multi-link design on the rear. It was offered in five different trim levels: SE, SE1, SE2, GT, and GT1.
The 2.4 L Twin Cam engine was carried over from prior generations, with upgraded power to 150 hp (112 kW; 152 PS) and 155 lb·ft (210 N·m) of torque. GM's 3400 V6 became available as an option on the SE and SE1, and was standard on all other trims. All Grand Ams included a four-speed automatic transmission for 1999, and Getrag five-speed manual transmissions were made standard on four cylinder models starting in 2000.
GT and GT1 models had 4-wheel disc brakes and a Ram Air induction system with an extra five horsepower and 5 lb/ft of torque over the 3.4 L V6 when installed in any of the SE-level trims. The SE2 trim was dropped in 2001, and new wheel designs were introduced along with bigger Delco stereos that changed from a 1.5 DIN size to a full 2 DIN size.
Half way through 2002, the Twin Cam 2.4 L engine was replaced by a 2.2 L Ecotec four-cylinder, producing 140 hp (104 kW; 142 PS) and 150 lb·ft (203 N·m) of torque. The SE models' body cladding was removed in2003 and anti-lock brakes and traction control were made optional on that trim. An MP3 player was added to the uplevel CD player in 2004.
The last Pontiac Grand Am rolled off the line at Lansing Michigan's, Lansing Car Assembly plant on May 10, 2005, after being replaced by the G6.
