Concept Car of the Week: Honda Kiwami (2003)

As part of Honda's exploration into new, clean-performing technologies, the Kiwami concept was created to test public acceptance of the idea of a large, fuel cell-powered luxury sedan.  Unveiled in 2003, the simple yet striking design seemed like a Japanese twist on the Renault Vel Satis concept, which shared a similar wedge profile, wide stance and minimalist approach.  However, the Kiwami found its own interpretation of modern luxury, expressed through elegantly integrated technology rather than with crystal champagne glasses.  Up front, a full-width LED strip headlamp sat flush with the flat bonnet and the rectangular bumper to create a design of primitive beauty.  Further examples of the same simple Japanese aesthetic are found around the car, including the uncluttered body panels and a full-width tail-lamp graphic that matched the front theme.  The dramatic proportions of the interior were closely related to the package of the hydrogen power plant. Unlike other manufacturers at the time, Honda engineers did not create a 'skateboard' fuel cell chassis below the cabin. Instead, a sideways H-shaped layout for the control unit, ultracapacitor, fuel cell stack, hydrogen storage and other components was used, helping to create a lower center of gravity.

Suzuki G70, Swift Range Extender at 2012 Geneva motor show

You will not find too many detractors when it comes to the Swift, particularly in its Sport guise, but its clean-living brother was one of the two highlights on the Suzuki stand. The rather convolutedly-named Range Extender was actually first shown at Geneva in 2010, but has since undergone further development. More interesting is the G70.

Volkswagen Iroc concept

The Iroc is a show car preview of a production coupe to be launched next year that will fill a gap in the Volkswagen model line up left by the demise of the Corrado 11 years ago. Volkswagen describe the Iroc as "transferring the globally successful Scirocco idea into the future" - the Scirocco Mk1 by Giugiaro being produced from 1974-1982, the Mk2 from 1982-1992. Like the Scirocco, the Iroc is a front wheel drive coupe with four seats - as opposed to the 2+2 seating arrangement of the only other sports coupe from Volkswagen Group: the Audi TT.
