Cadillac has officially unveiled the ATS Coupe at the North American International Auto Show.

Following a preview earlier today, Cadillac has officially unveiled the ATS Coupe at the North American International Auto Show.

Set to go on sale this summer, the ATS Coupe is heavily influenced by the sedan but features unique bodywork and a revised grille with the company's wreathless crest. The latter change has stirred a lot of controversy but Cadillac's executive design director, Andrew Smith, says “This new crest matches the lower, longer, leaner mantra of our current car designs, and reflects the evolution of our Art and Science philosophy.”

Smith went on to say “Our goal was to evolve the emblem design to integrate with the new vehicle form while maintaining the core graphic elements that preserve its strong brand recognition. This resulted in retaining the iconic ‘crest’ shape and color palette with geometric grid from the original Cadillac family ‘coat of arms.’”

Turning back to the ATS Coupe, it will be available with two different engines. The turbocharged 2.0-liter four-cylinder produces 272 bhp (203 kW) and 295 lb-ft (400 Nm) of torque, while the 3.6-liter V6 develops 321 bhp (239 kW) and 275 lb-ft (373 Nm) of torque. Both are connected to a six-speed automatic transmission - a six-speed manual is available on the four-cylinder - which can be paired to an optional all-wheel drive system.
