The sole Hummer entry at SEMA, the Upscale Performance H2
, carries a trump card in its considerable portfolio: a 450-hp supercharged V-8. Luxurious interior trim includes alloy metals and carbon trim, and leather trim that could make its way into the 2004 version of the H2. Seventeen-inch polished wheels and 37-inch tires complement Fabtech/Fox suspension mods front and rear.
Pontiac’s performance intentions for the future amount to three letters: GXP. The brand will launch the newly minted family of performance variants in 2004, with the introduction of a new Bonneville GXP powered by a new 4.4-liter, 280-hp version of the Northstar V-8. At SEMA, the GXP family included concepts for the rest of the vehicles in the current Pontiac lineup, some looking more than production ready.
The 2004 Bonneville GXP
is breathing through a 32-valve V-8 engine in its GXP iteration. New front and rear fascias and gallons of black paint grace the sleek concept, which Pontiac says will be modified somewhat before it enters production late in 2003.
A supercharged version of its stock 1.8-liter four-cylinder is shown in the Vibe GXP, making 35 percent more power than the stock motor. Lower ride height, 18-inch forged aluminum wheels and ceramic-coated brake calipers make it the toughest Vibe this side of Snoop Dogg.
The Grand Prix GXP also gets its suspension lowered, but the powerplant underhood is considerably larger — a 285-hp version of the 3800 V-6. Like the other GXP concepts it gets shadow-black paint, new instruments with metallic bezels, a more tightly tuned suspension and beefy brakes.
Pontiac’s Grand Am GXP delivers much of the same bite with a 275-hp supercharged V-6 and a better flowing exhaust system.
And the last concept in the new family, the Sunfire GXP sports a 180-hp supercharged Ecotec four with revamped instruments, metallic interior trim and a lowered suspension.
Elsewhere, Pontiac’s Sunfire American Tuner
show car addresses the needs of modifieds who might not be able to outlay the initial $12,000 or $15,000 for a basic compact. Loosely styled after the GTOs, the pieces are penned to fit existing Sunfires from 1995-2002. They include a spoiler, new rocker panels, side exhausts and a supercharger that boosts the engine to 190 hp.
Saturn’s portfolio of aftermarket and tuner cars will be growing, according to GM officials. While the 200+hp ION tuner Quad Coupe won’t be out until early 2004, all the pieces on the ION EFX
concept will be available through Saturn retailers starting next year. Those pieces include ground effects, aluminum pedals, carbon-fiber-look roof rails, a rear spoiler and lowering suspension springs contribute to the tuner-look package. The 140-hp Ecotec four in the ION gets HKS performance exhausts, too.
