Based on the saloon (which was North American Car of the Year in 2013), this coupe sits on the same 2775mm wheelbase as the four-door ATS but features a wider track.
Taking a page from BMW, Cadillac plugs the coupe’s “nearly perfect 50/50 weight balance.” The optional “FE3” sport suspension includes quicker steering, staggered wheels and tires, magnetic dampers, and a limited-slip differential.
All ATS Coupes are fitted with 18-inch wheels. Like its German competitors, it’s available with either rear-drive or all-wheel drive. Unfortunately, like the sedan there are no plans for a right-hand drive version.
The 2.0-liter turbo is tweaked for 14 per cent more torque versus the four-door and develops the same 272bhp—beating the BMW 428i's power-to-weight ratio. The optional 3.6-litre V6 puts out 321bhp but its 275lb ft of torque is actually 20lb ft down compared to the 2.0-liter. The coupe skips the base ATS sedan’s 202bhp, 2.5-liter four-cylinder.
Transmission choices are a 6-speed manual or automatic—with only the latter paired with the V6. Inside, the 2+2 layout is complemented with standard or available color heads-up display, radar cruise, rear cross-traffic alert, and motorized seat belts for front occupants. A 4G LTE telematics system with an in-car app marketplace is new for 2015.
Like the ATS sedan, the exterior styling of the ATS Coupe is refreshingly subdued compared to other Cadillac products. The roof, doors, rear fenders, and boot lid are unique to the coupe.
It’s also the first Cadillac to utilize company’s updated, more modest badge—losing the classic laurel wreath.
