General Motors demonstrated its progress on developing a future advanced engine technology for consumers that squeezes more miles per gallon of gas and reduces emissions. GM engineers have brought the advanced combustion technology from the laboratory to the test track and, now, to the highway in a driveable concept vehicle - a Saturn Aura equipped with homogenous charge compression ignition (HCCI).
GM demonstrated its latest progress with the HCCI technology during a media test-drive program in the Washington, D.C. and the New York City areas. Journalists drove the HCCI-enabled Aura concept on public roads to get a real-world feel for the efficient and low-emissions engine. HCCI provides up to a 15-percent fuel savings when combined with several additional advanced technologies, while meeting current emissions standards.
The Saturn Aura concept vehicle is capable of operating in HCCI mode during idle, in addition to highway driving. The HCCI operation at idle represents a significant technological advance that GM engineers believe could be the first for the industry. The breakthrough enables a wider range of HCCI operation, extending the efficiency-enhancing benefit of the technology.
Saturn announced today at the North American International Auto Show that production will may begin as soon as 2010 on a plug-in hybrid electric version of the Saturn Vue Green Line, expected to be the first regular production plug-in hybrid electric vehicle. Depending on a consumer’s drive cycle, the Vue plug-in hybrid will be the most fuel-efficient vehicle offered by a major automaker.
With its lean, taught bodywork stretched over a long wheelbase and wide track, the all-new Saturn Astra has an undeniably sporty stance. Fortunately, its European-inspired driving dynamics and energetic 1.8L Ecotec engine back up those aggressive good looks with commensurate performance, making the Astra prime material for all-out tuner treatment.
The Saturn PreVue crossover concept - revealed today at the New York International Auto Show - continues Saturn’s ongoing product revitalization and provides a glimpse of future Saturn vehicle designs. The three-door, four-wheel drive crossover offers a sporty interpretation of Saturn’s new design language and illustrates how it could be applied to a future version of Saturn’s highly successful Vue compact SUV.
With its dynamic design and quick and agile performance, the Sky roadster delivers a bold message about the next generation of vehicles from Saturn.
The Sky, introduced at the North American International Auto Show and slated for production in 2006, is the first vehicle to feature a new look that will influence Saturn’s entire future product lineup. The roadster will be followed by a new midsize sedan and a large crossover SUV as Saturn’s product portfolio doubles during the next 24 months.
Shape, color and sound affect the senses. With the Saturn Curve concept, a sinewy shape, warm colors and the aural delights of a supercharged engine warm the emotions of those who appreciate sophisticated and engaging automobiles.
The Curve signifies Saturn’s evolution, both in styling and product. Saturn is growing its portfolio, planning new vehicles and exploring dynamic, refined designs.
The Saturn Aura concept provides a clear preview of how the Saturn design element can be applied to a sporty medium sedan.
Aura is powered by a 250-horsepower 3.6L DOHC V-6 engine with variable valve timing. It’s mated to a six-speed automatic transmission with manual tap up/tap down shift controls. Safety performance is provided by roof rail-mounted head curtain side-impact air bags, side-impact thorax air bags, four-wheel ABS with traction control and StabiliTrak, GM’s electronic stability control system.
