GM to debut new Hummer at SEMA

General Motors provided details yesterday of its plans for the upcoming Specialty Equipment Marketing Association (SEMA) show, which opens in Las Vegas, November 4.

General Motors is using the backdrop of the SEMA show to unveil a new Hummer, announce future Performance Division offerings, feature several new powertrain applications, present an array of new accessories and show a trio of vehicles that led an assault on the Bonneville Salt Flats.

Hummer will unveil the new H2 SUT and a new interior for the H1. The H2 SUT features a reconfigurable mid-gate. For the H1, a host of interior updates – the first significant redesign in H1’s history – will add comfort, convenience and refinement.

GM will show the production versions of the Pontiac Bonneville GXP, Cadillac CTS-V and the Saturn ION Red Line which debuted as concepts at last year’s show.

The Pontiac Bonneville GXP features a 4.6-liter DOHC V-8 that delivers 275 horsepower and a performance-tuned handling package that includes four-wheel independent suspension, StabiliTrak and an electrically controlled transaxle with a 3.71 final drive ratio.

The CTS-V brings Cadillac will have a 400-horsepower, 5.7-liter V-8, six-speed manual transmission, large Brembo performance brakes, 18-inch wheels and tires, retuned shock absorbers and a host of interior and exterior styling refinements.

Inspired by the tuner car movement, the ION Red Line quad coupe features an integrated performance package including a 2.0-liter supercharged, intercooled version of the Ecotec four-cylinder engine, racetrack-bred suspension and unique styling. A specially prepared ION Red Line driven by Jim Minneker, a GM Performance Division engineer, set the land-speed mark for its class on the Bonneville Salt Flats in northern Utah. At SEMA, the ION Red Line is joined by the VUE Red Line, a limited-production sport utility featuring a lowered body, sport-tuned suspension and steering, ground effects and VUE’s new 3.5-liter, 250 horsepower V-6.

GM Performance Division will also debut a Chevrolet TrailBlazer SS, a 2006-model-year entry that will feature a Corvette-inspired V-8 engine, 20-inch wheels and a lower suspension than the current production model. The production TrailBlazer SS will be based on the TrailBlazer SS concept originally shown at the 2002 SEMA show.
