Design, Engineering Contribute to ATS Fuel Economy

Cadillac’s award-winning 2013 ATS sport sedan with the new 272 horsepower 2.0L Turbocharged engine today received an EPA fuel economy rating of 21 city and 31 highway mpg, evidence that its lightweight and aerodynamic design marries high performance and fuel efficiency.

The ATS is available with three engine options. The standard 2.5L four-cylinder engine with 202 horsepower offers an EPA rated 22 city and 33 highway mpg. The top-of-the-line 3.6L V-6 and 321 horsepower offers an EPA tested 19 city and 28 highway mpg.

ATS engines rank near the top of the industry for “power density,” or horsepower per liter. Unlike its European rivals, ATS takes regular unleaded fuel except for the 2.0L Turbo engine. And for that model, it is a recommendation not a requirement.  

“ATS is a no-compromise car,” said Don Butler, vice president of Cadillac Marketing. “The traditional sacrifices no longer apply.” 

From a design standpoint, the vehicle’s sharp, swept-back styling allows the ATS to slice through the air with minimal resistance. On its front fascia, the vehicle features active aero grille shutters that automatically close when additional engine cooling is not needed. Underbody aero shields help redirect wind around and under the car, which also contributes to reducing cabin noise. ATS achieves a coefficient drag of .299.

With a base curb weight of 3,315 pounds (1,503kg) ATS is the lightest luxury sport sedan in the world contributing to the car’s quick acceleration and nimble handling. Its lightweight construction also benefits fuel economy.

Attention to detail during the design of its all-new body structure and chassis resulted in an architecture that is strong and lightweight. ATS uses advanced materials in many locations, including:

    Ultra high strength steels throughout the car.
    An aluminum hood and magnesium engine mounts.
    A laminated windshield that is lighter than traditional tempered glass.
    Door trim panels made from natural fibers are lighter than the standard-issue plastics.
