The Opel Insignia | super speed cars is a large family car engineered and produced by Opel, the German subsidiary of General Motors (GM) since 2008, replacing the Opel Vectra. Launched at the 2008 British International Motor Show in London as the Vauxhall Insignia, the United Kingdom market name, the Opel Insignia name is used throughout continental Europe and Ireland, with Chinese-market versions badged Buick Regal. The Buick Regal will also be available in North America from late 2010. In Chile, the Insignia will retain the Chevrolet Vectra name as used by the previous Vectra model.
The rear sweeps down into a rounded bumper, emphasizing the aerodynamic framework that underpins the car’s design. The roof spoiler has the same effect, elongating the dynamic sloping roofline that is accentuated by roof rails and thus helping to ensure that the Insignia sedan’s sporty proportions are retained with the Sports Tourer. Also, the air is guided longer along the roof reducing the drag. Two vertical fins that bridge the roof spoiler and the rear lights have the same effect. The air flow is sharply cut off which also reduces rear end lift.
As in the Insignia sedan, GM Europe engineers fine-tuned the subtlest details to ensure excellent aerodynamic performance. These include rounding the front bumper corners and adding a flexible spoiler lip to its bottom end, giving the A-pillar a rounder shape, changing the exterior mirror to a wing form, and profiling the lower control arm in the rear suspension. Two underbody spoilers direct air over the rear axle to reduce drag and lift even more, while the three front air inlets have been optimized for efficiency. With a cD of just below 0.30, the Opel Insignia Sports Tourer is the most aerodynamic station wagon Opel has ever built. With a drag area of 0.69 m², it is better than many smaller cars.
