GTO. No other name in automotive history says muscle car like those three letters. When the GTO was introduced in 1964, its performance list included words like tri-power, four on the floor and a 389 cubic-inch V-8, and the car virtually defined true street performance.
Now the legend is back. Pontiac's 2004 GTO is a modern-day incarnation of classic street performance. When you turn the key and hear the throaty dual exhausts announcing the 5.7L V-8, you'll know you have your hands full. Compared to its '60s namesake, the new GTO sports a suspension that is tighter, an engine that's more powerful and a four-on-the-floor manual transmission that now boasts two additional gears. The car will hit 60 mph (97 km/h) in about five-and-a-half seconds, and run the quarter mile in under 14 seconds.
The completely new GTO isn't just about horsepower, of course. Its unique personality includes impressive cornering abilities, a smooth ride and surprising comfort. But the heart of the GTO is indeed a truly awesome 5.7L LS1 V-8 engine, also known as the base powerplant for the Chevrolet Corvette. The LS1 produces an estimated 350 horsepower (261 kW) at 5,200 rpm and with 365 lb-ft. (495 Nm) of torque, it has no problem leaving a stop with purpose.
