New Kappa rear drive architecture for compact and sporty GM cars
Saturn Curve concept demonstrates sleek coupe application
Chevrolet Nomad concept creates new vehicle category
The new Kappa architecture is the foundation for the Pontiac Solstice production model as well as several exciting concept vehicles that demonstrate its adaptability. Hydroformed frame rails, which run the length of the vehicle, are the basis of the chassis, while additional stampings form a rigid structure onto which the bodywork is attached. Independent front and rear suspensions with forged aluminum upper and lower control arms contribute to responsive handling. Near 50/50 weight distribution ensures a balanced handling feel. Propulsion is provided by the all-aluminum ECOTEC four-cylinder engine. Technologies, including intake- and exhaust-cam phasing and electronic throttle control are employed to maximize volumetric efficiency. The new Kappa is an adaptable platform - as demonstrated with the Chevrolet Nomad sport wagon and Saturn Curve 2+2 coupe concept vehicles. The Nomad rides on a longer wheelbase than the Solstice for added rear passenger room, and the expressive Saturn offers a sophisticated, performance-oriented driving experience.
Pontiac Solstice: A new dimension to Pontiac's performance renaissance
Bringing the popular concept car to life, GM has announced production of the Pontiac Solstice roadster as a 2006 model. The vehicle is expected in dealer showrooms in fall 2005. Built on GM's new Kappa architecture, the production model remains true to the original Solstice concept first shown at the 2002 North American International Auto Show (NAIAS) in Detroit, featuring rear-wheel drive, two-passenger seating and a reverse hinged clamshell engine hood. Power is created by a new 2.4-liter version of the ECOTEC DOHC four-cylinder 170 hp engine. At the start of production, the Solstice will be offered with a close-ratio Aisin five-speed manual transmission. Faithfulness to the concept can also be seen in the Solstice's proportions, which are comparable in terms of overhangs, wheelbase and track width. The interior is driver-oriented, with a clean design and intuitive controls. Unexpected details include a body-color extension into the passenger compartment that gives the Solstice an integrated appearance when the top is down. In fact, the top folds flat into the rear clamshell opening, providing a sleek appearance.
Saturn Curve: Supercharged coupe has refined flair
Demonstrating the versatility of the new Kappa architecture, Saturn is unveiling its Curve concept coupe. Its design abounds with interesting details that emphasize its contemporary aesthetic, as well as its sports car roots, including roof pillars that are concealed by a wraparound canopy of glass - creating the look of a "floating" roof panel. Sports car performance is derived from a supercharged 2.2-liter ECOTEC four-cylinder engine that produces more than 200 hp and more than 270 Nm of torque. Also, a front-hinged clamshell hood is complemented by a rear-hinged trunk lid. The forward-opening hood is a nod to great sports cars of the past, while the opposite-opening trunk lid creates interesting design symmetry when both panels are in the up position
Chevrolet Nomad: A sports wagon that emphasizes sport
The Nomad concept car can be categorized as neither a sedan, wagon, SUV nor any other kind of vehicle known to date, but it conveys presence and practicality. The Nomad represents another line of thought when it comes to leveraging the new Kappa sports car platform. To make room for rear-seat riders in its 2+2 configuration, the Nomad rides on a wheelbase that is five cm longer than other Kappa architecture-based concepts. The Nomad team created a forward-thinking and forward-looking design while evoking the spirit of the 1954 Chevy Nomad concept vehicle, including round headlamps mounted on gently curving fenders, a trademark Corvette grille and a forward-sloping B-pillar. The new Nomad goes even further, incorporating clever details to accommodate large, bulky items, such as a removable rear roof panel and a unique folding tailgate. A sliding cargo floor extends over the folded tailgate so items placed on the load floor can easily be pushed into the cargo area.
