Bigger, better, and bossier, the 1997 Pontiac Grand Prix sits on a new Wide Track W platform that it shares with the Buick Century.  A longer and wider wheelbase increases cabin room for more passenger comfort, but also improves handling and overall stability on the road.
The 1997 Grand Prix is offered as a base SE, GT, or GTP package sedan and a GT and GTP coupe.  While the SE sedan retains the previous 3.1-liter, 160-hp V6 and is reserved more for fleet use, the GT sedan and coupe gets a whole new 3800 engine.  The 3.8-liter V6 hits 195-hp on its own, but with the GTP supercharged package, that gets boosted to 240-hp.  Though all models come only with a 4-speed automatic, in the GTP Pacakge, you're able to choose between normal and performance modes.  
Other changes to the 1997 Grand Prix include standard ABS brakes, dual front and side impact airbags, and traction control on all models (the GTP does not have traction control).  A restyled knob-happy dashboard suffers a little from overkill, but nice options such as the heads-up display are driver favorites.  Standard on all trims, even the SE, are power locks, windows, and mirrors, air conditioning, fog lights, a driver information center, and daytime running lights.  The GT adds leather trim, variable effort steering, and cruise control.  
The 1997 Grand Prix has benefited greatly from its redesign, becoming a more powerful, more stylish, and more popular car.  The new 3.8 V6 is a hit with drivers who are looking for speed, instant acceleration, and a sporty feel.  Handling is praised, and the extra elbow and legroom in the car is much appreciated.  But Pontiac seems not to have addressed the issues which have bothered Grand Prix owners for a while, namely the cheap plastic parts that break easily.  Door panels are the biggest culprit.  Build quality and extensive repairs are common complaints.
