New Webasto Double Glass Panel Sunroof Lets Light Shine Into 2008 Cadillac CTS

Leading-edge UltraView design allows almost 70 percent of roof to let in natural light

ROCHESTER HILLS, Mich., Nov. 5 -- Cadillac applied its most comprehensive design and engineering efforts into its new 2008 CTS, including the expertise of Webasto, the global roof systems leader. The result of the partnership is the UltraView roof, a new take on an emerging growing consumer trend and a key feature on the critically acclaimed new Cadillac CTS.

The UltraView roof is one of the largest of its kind in a sedan: almost 70 percent of the car's total roof surface is glass to admit natural sunlight for both front and rear-seat passengers. The roof consists of two glass panels -- both UV-protected -- arranged in tandem. Like a traditional sunroof, the front panel of glass can tilt for venting or, when opened, retracts and stows under the back panel thereby letting fresh air in -- but with the unique advantage of continuing to provide light and a view of the sky to rear seat occupants. For those times when a softer light is preferred, a retractable power interior shade is at the driver's disposal.

"The roof's operation and underlying mechanisms are based on Webasto's proven high-quality tilt-and-slide sunroofs, but with the ingenious addition of replacing the metal roof immediately behind the opening panel with glass," said Andreas Weller, vice president business development, Webasto Roof Systems, Inc. "This gives rear seat passengers in the CTS the benefit of additional light, but avoids the forming of two holes in the roof and the associated cost, complexity and styling trade-offs.

"This exceptional project was in full partnership with GM, ranging from the conceptual stage to after the consumer takes delivery of their new Cadillac CTS," said Weller. "We did not just fill a list of specs. Webasto was commissioned to take on a significant role in the entire interface of the design process, including how this new roof could impact the body structure and styling. It has been a very collaborative effort, including Webasto's involvement; from integrating this roof into the entire vehicle design; to crash, squeak-and-rattle and wind-noise testing; to production plant needs, sales, marketing and service after the sale."

Market research shows that more consumers prefer the full open view and feel of expanded roof systems -- a specialty of Webasto. Automotive designs are trending towards sleeker, more aerodynamic and more dramatic body styles. Innovative roof systems like the CTS' UltraView provide not just a feeling of openness but also a real open-air and light option.

"We know first hand from our global reach and experience that traditional roof systems are being replaced in many markets by more innovative sunroof options," said Weller. "Consumers are demanding new features on their vehicles every year -- and the roof area was about the only remaining place left on vehicles to incorporate innovative and attractive design cues. Webasto has used its decades of expertise to pioneer roof systems that are functional, attractive and versatile -- something which is reflected in the 2008 Cadillac CTS."
