21st Place: Pontiac Grand Prix

 

With the Grand Prix, Pontiac attempted to blend the virtues of a sporty coupe with those of a family sedan, and failed spectacularly. Instead of mixing the two vehicles’ strong points, it incorporated their weakest ones into the vehicle, leaving it with the poor visibility and rear seat space that results from the car’s coupelike styling, and the stiff ride that results from the firm suspension tuning. But the Grand Prix is still a rather large car, and still handles like one. The only positive sporty quality that made it into this vehicle was the reasonably powerful V6, and even that is only a standard-issue GM powertrain.

 

As noted, the Grand Prix rides very stiffly. Bumps and other road imperfections are poorly filtered, and the ride feels unsettled even at highway speeds on smooth pavement. Road and engine noise are pronounced, but wind noise is reasonably well-muted. The car's firm suspension tuning prevents excessive body roll in cornering, but the slow and unresponsive steering keeps the car from feeling sporty, and it feels its size in fast turns. The 3.8-liter V6 at least delivers prompt acceleration, the only remotely sporty aspect of the driving experience, but even that area it falls well short of many competitors. Fuel economy is good, especially considering the car’s competitive acceleration.

 

Inside, the front seats are adequately comfortable, but the poorly-contoured seat cushion feels lumpy, and a bit too firm. And the rear seat is one of the worst in this group, less-comfortable than most compact sedans'. The sporty roofline eats into the headroom, and the seat had to be mounted quite low to compensate, which, along with the short cushion and minimal leg and footroom, destroy any levels of seat comfort. The high window line further diminishes rear passenger visibility, especially for smaller occupants. The dash is coated in cheap, hard plastic trim pieces that at least fit together well. The instruments are angled towards the driver, and are generally simple to use. The gauges are quite clear and notably large. Getting in and out of the front seats is fairly easy, but the low roof and small footwell greatly complicate entry/exit to the rear. The driver sits comfortably, but the sloping windowline inhibits rearward visibility. The trunk is roomy.

 

The Grand Prix did not excel in crash testing. It earned five stars for the driver and four for the front passenger in the NHTSA frontal crash test, but an three stars for both the driver and rear passenger in the side crash test (tested without the optional side airbags). It earned a Good rating in the IIHS offset crash test, the highest of four ratings, but its head restraints were rated Poor, the lowest of the four. The IIHS has not evaluated its side-impact protection.

 

The Grand Prix reviewed here came in at $24,947, good for this class, and includes the GM-exclusive OnStar system and a remote-starting system. However, the Grand Prix does not offer such items as a power passenger’s seat, torso-protecting side airbags, or stability control on the trim reviewed here, the only one with the standard naturally-aspirated V6.

 

Overall, the Grand Prix is a large sedan priced among midsize ones. Yet in favor of sporty pretensions, it eliminates all possible large sedan benefits, such as a comfortable ride and a roomy interior, and still isn’t inexpensive. Its standard V6 does provide a decent mix of acceleration and fuel economy, and the trunk is adequately roomy, but those not-uncommon strengths alone are not nearly enough to elevate it from the back of this group.
