'WTCC Ultra' Vision of a New Generation of Touring Car
The World Touring Car Championship Ultra (WTCC Ultra) is more than just a stunning locally designed concept car. The vision of a new generation of touring car is in fact drivable. It received tremendous attention from media and the public at its world premiere at the 2006 Paris Motor Show.
The WTCC Ultra started its life in GM Daewoo's Advanced Design Studio in Incheon, where the initial concept and early design work were developed.
The dynamic exterior design and striking interior of the WTCC Ultra were coordinated and approved by GM Vice President, Global Design, Ed Welburn (U.S.) and David Lyon, Executive Director, GM Asia Pacific Design (Korea). GM Vice Chairman, Global Product Development, Bob Lutz was involved in the project from the very beginning and enthusiastically supported it.
"The eye catching WTCC Ultra is a fine example of GM Daewoo's design capabilities and how GM design teams around the globe are working closely together on an exciting project like this," said Lyon.
The compact WTCC Ultra (length/width/height with spoiler: 4,324/1,906/1,569 mm, wheelbase: 2,650 mm) is equipped with a powerful 1,991-cm3 diesel engine that generates 139 kW/190 hp.
The basic version of the four-cylinder engine is the common rail unit with four-valve technology and variable turbine blade geometry currently powering the GM Daewoo Winstorm and Tosca Diesel. The increase in performance was achieved by raising the turbo boost pressure.
The WTCC Ultra has a sophisticated independent wheel suspension on McPherson struts on both axles. The lower wheel control at the front is taken care of by an A-frame arm, while at the back, two additional wishbones and one trailing arm link the wheels precisely to the chassis.
To keep the weight as low as possible, the designers of the WTCC Ultra made plenty of use of modern lightweight materials. The body parts are finished in "Stealth Blue," and are made of a glass fibre and carbon fibre laminate. The flat underbody of the fully functioning touring concept car, which also graphically divides up the vehicle because of its dark color, and the front and rear spoilers are made of a plain weave carbon fibre composite.
The window frames and the air intake grilles at the front are finished in semi-gloss dark gray. They make an attractive contrast with the glossy silver-painted wheels and the polished aluminium door handles, number plate and centrally positioned tailpipes.
