'98 Pontiac Trans AM
Fresh Face And All-New, Aluminum V-8 Firepower For The Bad-Boy Firebird
Pontiac's Trans Am is about two things: absolutely pavement-eating performance and flashy styling. For '98, there's a new 305-horsepower aluminum V-8 to crank up the wick under the car's already attention-grabbing look.
Frankly, having our bright-red test unit in the driveway for the daily commute was like being 12 years old and waking to find a rocket-powered backpack under the Christmas tree. Here's what a track test and a short session on the wing in Pontiac's fastest factory Firebird brought to light.
This Firebird is extremely quick. We've heard some loose talk in engine-tuning circles that the end of the old small-block meant GM would have to start from scratch to find power tricks for the all-new LS1. But we're here to tell you, we don't miss last year's LT1 or even the high-output LT4 engine a bit. So if you're crying over the end of either of those powerplants, dry your eyes and gander at the acceleration numbers this car generated. Case closed.
Not only is this high-spooling aluminum-block cast-iron-cylinder powerplant the sweetest-running Firebird engine we've ever sampled, it makes positively incredible amounts of muscle for an assembly-line V-8. In the recent past, only hand-built, blueprinted small-blocks could flick a 3500-pound F-car to 60 mph in a tick over 5 seconds.
The quarter was scorched in 13.4 seconds at better than 107 mph. So with a 15.5-gallon fuel tank will you be making lots of pesky stops for a gas-thirsty beast? Depends on how you drive. Drive it like we did, and you'll be on a first-name basis with every service station operator in your metropolitan area. But show some restraint, and the city economy should be about 17 mpg with an incredible 26 on the highway.
Unquestionably, the two big reasons the LS1 came across so well were the mellower sound (thanks to the 22-percent-larger mufflers and pipes welded up from 2.25-inch and 2.75-inch stainless) and the slick-shifting Borg-Warner six-speed manual. We found ourselves finger-flipping up and down through the gears for no reason other than to hear this rev-crazed engine in song to 6000 rpm.
