Pontiac G8 GT
From Pontiac press: The GT model ups the ante with the introduction of the 6.0L small-block V-8, producing 361 horsepower (268 kW) and 385 lb.-ft. of torque. Zero-to-60 times of 5.3 seconds are possible with the six-speed Hydra-Matic 6L80E automatic transmission linked to a standard limited-slip differential.
Both transmissions feature a uniquely tuned Driver Shift Control, allowing the driver to select three distinct shifting styles. In normal automatic mode, the transmission is geared to provide an optimal blend of performance and fuel economy. Sliding the shifter right into the manual shift gate selects a "Sport Mode," altering the automatic shift points to maintain higher torque and greater engine control.
For driving enthusiasts who want ultimate control, moving the shifter up or down in the manual shift gate provides complete control over each shift point. In this mode, the transmission will not automatically up-shift at any time, although a rev limiter will prevent the engine from exceeding the red line. For safety reasons, the transmission will down-shift if engine rpm drops to a point where a stall is possible.
