Chevrolet Aveo RS Show Car











General Motors is firing back. The new Chevrolet Cruze debuted last month at the Los Angeles auto show; the Spark is on its way; and Chevrolet is completing the trifecta with the Aveo RS show car, a thinly veiled preview of the long-awaited Aveo replacement.
Knowing full well that the replacement needed to greatly improve upon the existing Aveo, Chevrolet has made the new hatchback wider, longer, and more spacious that the one it will replace. For the show car, Chevy has gone all out with special design cues including big front fender flares, extra-large brake cooling ducts with pushed-out fog lights, and big air inlets trimmed in both brushed and polished aluminum.

Other elements are more likely to make it to the production car, including the exposed, aluminum-trimmed headlights and round taillights, elements Chevy says were inspired by motorcycles. Turn signals integrated into the mirrors, and rear door handles tucked into the C-pillars, are also likely to carry over to the production model. The chrome, center-exit exhaust tips, racy roof spoiler, and aluminum-trimmed, tinted tail lights are a bit less likely.
While some of these bits might not be found on the production car, they may be available as accessories. Chevy says it's targeting younger buyers and enthusiasts and hopes to hook them with the kinds of personalization options that have been such a hit for small-car competitors Scion and Kia. For the show car, Chevy even crafted a special silver engine cover with aluminum accents flanked by wheel-colored honeycomb grilles, and blue-rimmed coolant and power steering caps. The company hasn't said yet which, if any, of these show car items will actually be offered as factory or dealer upgrades.

the XTS Platinum concept car, Cadillac aims to re-imagine "the luxury sedan as a personal headquarters." At an inch longer than the Escalade Platinum Hybrid, and 2.3-in wider and 1.1-in taller than the CTS, the large luxury sedan is a rolling showcase for the brand's Art and Science design language and a probable direction of its future production cars.
Modeled after the Platinum philosophy, the XTS features hand cut-and-sewn interior. Dark materials adorn the steering wheel and overhead compartment, contrasting against the prominent light cream interior color. The dash is a harbinger of the future of in-car electronics for the Cadillac brand. Organic Light-Emitting Diode (O-LED) displays replace the traditional gauges and screens, while the deployable touch-screen navigation system supplants the majority of buttons and switches on the dash. The panels appear black until the car is started; a "dead front" design, as dubbed by the designers, that aims to give the dash a flowing appearance.
The exterior "is the antithesis of the conventional three-box sedan, suggesting the active evolution of Cadillac's design language," according to design director Clay Dean. It features a sweeping profile and angled beltline to suggest forward motion. Vertical lamps sit at all four corners, while the lights up front receive adaptive lighting that adjusts direction depending on the angle of the front wheels.
Under hood is a paring of General Motors' direct-injected 3.6L V-6 and a plug-in hybrid system. The combination makes an estimated 350-hp and 295 lb-ft of torque, and can propel the XTS under electric power alone. When plugged into a power outlet, GM says the battery can recharge in about five hours. The engine routes power to all four 20-in wheels, which are wrapped in Bridgestone rubber. Widely believed to be underpinned by GM's front drive-based Epsilon II platform, the XTS also features magnetic ride control, using shocks that are capable of adjusting damping in indiscernible amounts of time.

we took a spin in the Opel Insignia OPC (which stands, not too imaginatively, for Opel Performance Content), the highest performing model in the extensive and lauded Insignia lineup. We posited that car might point the way toward the revival of a Buick performance subbrand like T-Type. Well, now we know it's likely to be called GS if the Buick Regal GS show car bowing at the 2010 Detroit show is any indication, though it's still not confirmed for production. Most of the content is lifted directly from the OPC, from the aggressive restyled fascias with vertical air inlets in front, dual exhaust outlets and a diffuser in back, as well as unique rocker panels, integrated rear spoiler, and special Olympic White paint. The jet-black interior features Recaro seats with white stitching, a flat-bottom steering wheel, and piano-black trim.
Mechanical upgrades borrowed from Opel include 20-inch forged wheels, vented and drilled Brembo brakes with 14 x 1.2-inch vented and cross-drilled front rotors, four-piston, high-strength aluminum calipers, and high-performance pads. An adjustable suspension lowers the body by 0.4 inch and features HiPerStruts in front that help reduce torque steer and maintain negative camber during cornering for improved grip, improving road feel and reducing undesirable feedback in bumpy corners. The Interactive Drive Control System (also available on Regal CXL 2.0L turbo models) delivers enhanced vehicle stability and greater driving safety, while also adapting the damping and driving characteristics to the driver's preferences. Normal, sport, and GS modes tailor the suspension settings, throttle response, shift pattern, and steering sensitivity through the variable-effort steering system.
The big difference relative to the OPC is replacement of that car's 2.8-liter turbocharged 321-horsepower, 321-pound-foot V-6 with a higher-output version of the 2.0-liter turbo that's expected to produce at least 255 horses and 295 pound-feet. That abundant force is routed through a six-speed manual to a Haldex all-wheel-drive system that includes an electronically controlled limited-slip rear differential. Why ditch the six? According to Craig Bierley, product marketing director for Buick, that engine would likely incur a gas-guzzler penalty, and in any case, the design brief was to build a car that could accelerate to 60 mph in the fives, and the 2.0T was easily able to accomplish that while achieving considerably better fuel economy than the V-6.
Bierley also assured us that the rock-hard damper tuning of the IDCS system's OPC setting (now GS) would be softened just a bit for the U.S. market. Trust us -- this is a good thing in a country that maintains its roadways so much worse than the Germans do. Only the Insignia's normal setting felt tolerable, Sport prompted minor kidney trauma, and when in OPC (the max setting) one fears that conversation might imperil one's tongue. We're also hopeful that Buick will tune the four-cylinder's exhaust to eliminate the annoying drone we recently experienced in the OPC at 2000 rpm. Grip from the Pirelli PZeros was impressive back in November, and we expect much the same from the new 245/35/ZR20 Bridgestones. The steering feedback, braking feel and performance, and general chassis poise felt equal with the German sport-sedan competitive set on the Opel Insignia, and the same should hold true for the Regal GS. It will admittedly take some work to get the driving public to consider a Buick competitive with an A4 Quattro, but the first step is delivering the goods.
