starting to arrive in dealerships, General Motors
has already made plans to offer up an even higher-performance model,
which was introduced in New York earlier this week.
The
G8 GXP gets a bump up to the LS3 engine, which is shared with the
Corvette. In the G8, the engine makes 402 horsepower and 400 lb-ft of
torque, when it's paired to a six-speed manual. A six-speed automatic
will also be available, and if it's selected the LS3 puts out an extra
2 lb-ft of torque. The numbers? According to GM's preliminary tests,
it's capable of accelerating to 60 mph in 4.7 seconds, and
will do the quarter mile in 13 seconds flat, with a trap speed of 108
mph. That compares favorably to the Dodge Charger SRT8.

To
go along with the extra power, the G8 GXP features differently tuned
suspension and steering components, while the brakes have been upgraded
to Brembo calipers featuring four pistons up front and 14-inch
disc brakes. The G8's wheel and tire package consists of 19-inch alloys
with a similar pattern to what can be found on high-performance Holden
HSV vehicles.
Inside, the changes to the G8 GXP are simple but
straightforward. The car receives new two-tone leather-trimmed front
seats with additional bolstering, plus color matched instruments and
aluminum pedals.
The new G8 GXP will be available late 2008 as a model year 2009 product.
