Available in late spring 1998, the basic design of the fifth-generation Grand Am was shared with the
Oldsmobile Alero (also new for 1999) and
Chevrolet Malibu (introduced in 1996). The length was shortened slightly, but the wheelbase grew by more than three inches (76 mm). The suspension was now fully independent, with a revised MacPherson-Strut design upfront. The rear suspension is a more refined Multi-link design. The new Grand Am was offered in five trim levels: SE, SE1, SE2, GT, and GT1. The 2.4 L Twin Cam engine was carried over, with 150 hp (112 kW; 152 PS) and 155 lb?ft (210 N?m) of torque. GM's 3400 V6, previously exclusive to their minivans, became available as an option on the SE and SE1 and was standard on all other trim levels. For 1999, all the Grand Ams featured a 4-speed automatic transmission. The GT and GT1 also included 4-wheel disc brakes,
[38] and all Grand Ams until 2003 included standard ABS and Traction Control (made optional on SE from 2003). The GTs also had a Ram Air induction system, providing 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 2000 models added a Getrag 5-speed manual transmission as standard equipment with the four-cylinder. On GT models, the badge on the front fenders now read "RamAir V6", instead of "V6H.O." on 1999 GT's. ASC Creative Services designed the Grand Am SC/T for the SEMA show circuit, which was the concept design for the Ram Air hood and body package. The SC/T later became an appearance package, beginning in 2003. A road test by
Car and Driver showed a 0-60 mph time of 7.7 seconds in a GT sedan with an automatic.

For 2001, the SE2 trim level was dropped, a new family of Delco stereos and new wheel designs was introduced. The radio size in 2001 also changed from a 1.5 DIN size to a full 2 DIN size. Halfway through 2002, the Twin Cam 2.4 L engine was replaced by a new 2.2 L
Ecotec four-cylinder, which had improvements over the engine it replaced, but produced less output; 140 hp (104 kW; 142 PS) and 150 lb?ft (203 N?m) of torque. Changes for 2002 also included a stationary cup holder in the center console as opposed to a removable one.
The body cladding on SE models was removed in 2003, a change which affected other models throughout Pontiac. Also in 2003, anti-lock brakes and traction control were made optional on the SE. In 2004, an MP3 player was added to the uplevel CD player. In 2005, Pontiac began phasing out the Grand Am lineup for the new G6 replacement. SE sedans were retained for fleet sale and GT coupes were the last Grand Am model available for public sale.

The final Grand Am rolled off the line at Lansing, Michigan's, Lansing Car Assembly plant on May 10, 2005, shortly before the Lake Orion, Michigan plant began assembling G6 coupes. This was also the last car to be made at Lansing's old Fisher Body plant.
