From the official Press Release:

Chevrolet Silverado 427 Concept

Twenty-seven vehicles will be on display all week in the GM SEMA booth, including 14 Chevrolets; two Cadillacs; four GMCs; two HUMMER H3s; two Pontiac Solstices; two Saturns; and one Buick Lucerne partner vehicle. There will also be a top-secret performance car, developed in conjunction with one of GM’s more notable celebrity partners, in the stand.

This year’s GM SEMA lineup also heralds the return of "4-2-7" numbers in the Chevy Silverado 427 - a concept that demonstrates the new Silverado’s powerful performance parameters, powered by a 7.0-liter LS7 unit, the same Gen IV small-block V-8 that powers the Corvette Z06.

"Talk about American muscle – our all-new family of full-size SUVs dominates the segment, and our all-new, full-size pickups are positioned for similar success,” said Michael Jackson, GM North America vice president of marketing and advertising. “Our new pickups were designed and built with personalization in mind, and it’s great that customizers and enthusiasts agree.”

Cadillac teams up with DUB magazine for a unique version of the Escalade EXT.

In addition to the three Silverado concepts, Chevy features pickups and SUVs decked out for both on- and off-road adventures and that pay homage to Chevy’s relationships with the U.S. Ski Team and Major League Baseball.

GMC shows off a Sierra NFL Crew Cab with an NFL interior and exterior theme; a Sierra Texas Extended Cab to fend off pesky competitors in the biggest-selling pickup market in America; a Yukon Denali XL “Big Max” that’s the most capable, feature-packed, powerful Denali ever; and a Sierra All Terrain Crew Cab.

For what concerns the Crossover SUV segment, the Cadillac SRX Sport, which receives a significantly redesigned interior for ’07, gets a Seventh Avenue makeover by upscale women’s clothing designer Dana Buchman.

The Saturn Outlook Adventure shows how accessories can help the all-new crossover complement a customer’s outdoor lifestyle.

HUMMER brings two H3s: an E85 ethanol-capable model with available genuine HUMMER Accessories and the H3 Open Top, with a canvas roof by ASC and decked out with real HUMMER accessory products.

In addition to trucks and SUVs, GM will feature a 1969 Chevy Camaro customized by “Mr. October” himself, Reggie Jackson, and Buick makes its first custom partnership appearance in the 43-year history of SEMA with Rick Bottom’s street-smart interpretation of the Lucerne full-size sedan, the CXX Luxury Liner. Buick has 10 other customized Lucernes spread throughout the show.

Two ultra-performance versions of the hot-selling Pontiac Solstice will be on display, a GXP-R concept and a Sports Car Club of America race-prepared Solstice Club Sport Z0K. The newest star of SCCA, Solstice finished its debut season with three National Championships – one in Showroom Stock B Club Racing, and one each in C Stock Open and C Stock Ladies Solo autocross competition.

The GXP-R is a concept of a new turbocharged Solstice model that would include restyled front and rear fascias, a more aggressive spoiler, 19-inch cast chrome wheels and multiple other enhancements.

In addition to the Solstice, Saturn will show off Gravana Speed Shop’s interpretation of the Saturn Sky roadster. Gravana, working in conjunction with GM Design, has pushed the Sky’s styling to the limits with its highly customized concept treatment that enhances the sleek, crisp and modern lines of the production vehicle while providing a cutting-edge visual design appeal.

GM also will show off a growing portfolio of crate engines and accessories designed and engineered specifically for GM vehicles by GM: there are in total more than 100 products designed at the GM Accessory Design Studio.

Jackson said shows like SEMA help showcase the ingenuity of GM engineers and designers, and let customers know what they can create in their own garages. "We're providing our aftermarket partners, our own accessories and Performance Parts operations and automotive enthusiasts with the best vehicle canvas on which to create parts, pieces and components that look cool and go fast,” he said. “These vehicles feature beauty, race-proven technology and production components that real people can buy and drive – today.”
