MT's first test 2009 Pontiac G8 GXP

Your bargain priced BMW M5 has almost arrived, and Motor Trend has just taken it out for a first drive. It's amazing that anyone and everyone that has had a chance to drive the GXP compares the $40K car to the previous generation $70K M5, but the proof is in the pudding.



By now, you know the G8 is based on GM global rear-drive-chassis architecture born and bred in Australia. The base V-6 and 361-horse V-8 GT versions are currently on sale and playing to solid reviews. The GXP is the only version you can get with a six speed stick, currently. The G8 wasn't designed or built in Detroit, but it's a true Pontiac, and variations on this theme are sold as Holdens, Daewoos, Opels, Vauxhalls-even Buicks in China and Chevys in the Middle East.



Under the hood is the latest version of the venerable Chevy small block, the LS3. Measuring out at 4.2 liters, it grunts out 415 horsepower and as much torque. Only the ZR1 and Cadillac CTS-v's supercharged version put out more power from the factory right now. The GXP even runs on regular gas, but it will carry a gas guzzler tax with it.



With all the added power additional upgrades are a no brainer. Increased stopping power comes from Brembo brake calipers, clamping 14.0-inch rotors front and 12.8-inchers aft. The already competent GT suspension is tuned for the GXP. the biggest change is larger front and rear anti-roll bars. The shocks are stiffer, and the rear balljoints are revised. Nineteen-inch alloy wheels are standard, as is summer-rated performance rubber (all season tires are also available). Calibration of the power rack-and-pinion steering is unchanged.



Styling updates are minor. The front and rear fascias are GXP-specific. Overall the car has a stronger, more muscular look, without giving it away as anything too special in those stoplight races.



Inside you'll find bolstered seats that hold you in place for the ride. Rubber trimmed pedals and a thickly padded steering wheels wrap up the interior mods.



The GXP is slightly bigger and heavier than the previous generation M5, but beats it in performance. The previous-gen M5 ran 0-to-60 in 4.5 seconds; the manual trans G8 GXPs match that. The Bimmer grips to 0.84 g on the skidpad, the Pontiacs stick to 0.88-0.90 g. The BMW stops from 60-0 in 116 feet, the Pontiacs from 111-117.



Overall, the G8 GXP represents a great value, and a nice car all around. It is by no means a world beater, but where else will be find it's level of luxury and performance for the price?
