Chevrolet is presenting a new production model and two new show cars at the Paris Motor Show this week.

Featuring environmentally friendly hybrid technology, the S3X gives a glimpse into potential future propulsion systems (to be revealed in Paris). When the production version is launched in 2006, it will be the first diesel-powered Chevrolet in Europe. It will also be the first vehicle in the line-up to be developed entirely by GM DAT.

The S3X also offers a preview of possible styling cues for future Chevrolet models, with flared wheel arches filled by 20-inch wheels, metal inserts in the front and rear bumpers, horizontal vents in the wings and jewel-like front headlamps in which the light is diverted by cylindrical prisms. There’s a large, louvered glass roof and the rear window can be opened separately to make the luggage compartment readily accessible without needing to open the rear flap.

The S3X study has room for three rows of seats – and thus seven passengers – and a long wheelbase of around 2.70 metres. The design of the interior is dominated by real wood and metal, while the infotainment system includes a DVD-based navigation system linked to a 7 inch monitor.

Chevrolet’s M3X show car offers a glimpse of the next generation of the popular Matiz city-car, the production version of which will be on sale in the market in spring 2005. It features a round LED front headlamp design, which is matched at the rear by the round tail lights, where you’ll also find a roof spoiler and twin, centrally positioned exhaust pipes.

There’s a large, glass panorama roof that can be pushed half way back, while the interior is dominated by blue fabric and metal applications on the gear lever, steering wheel and air vents.

At 1.5 m, it stands taller than most city cars and the wheelbase of just under 2.35 m is also above average. The 1.0-litre four-cylinder engine generates 64 hp at 5,400 rpm and a top speed just over 90mph.

The front-wheel drive Kalos three-door will be in UK showrooms from March 2005.  The new look is underpinned by aerodynamically optimised add-on body parts at the front and rear, modified bumpers and side sills. The interior also has a fresh and modern appearance, with additional stowage spaces and a two-colour facia.

The three-door Kalos will be available in the UK with a choice of two four-cylinder petrol engines: a 1.2-litre unit with 72 hp and a 1.4-litre 16-valve version with 94 hp. The 1.4 accelerates from 0 to 62 mph in 11.1 sec and has a top speed of 109 mph.
