Presenting its own unique take on an elegantly efficient design formula that has earned the ATS Sedan kudos around the globe, the 2015 Cadillac ATS Coupe boldly rolled into the limelight in Detroit. With its first compact luxury 2-door model, the automaker hopes to entice a new group of young affluent enthusiasts to slip behind the wheel of a vehicle it claims will deliver the best power-to-weight ratio and the most engaging driving dynamics of any player in its segment.

While retaining all of the distinctive visual cues introduced on the ATS 4-door, this new coupe is even more aggressively styled and proportioned than its sedan sibling with the only shared sheetmetal being the hood stamping. Both ride on a 109.3-inch wheelbase, but the coupe is slightly lower and wider - the latter reflecting its more expansive track dimensions. In addition to a faster roofline and shorter front/rear overhangs, the ATS Coupe also has unique fascia treatments that include the first application of Cadillac's new-look crest. Primary illumination for base ATS Coupes comes from projector beam headlamps, but the Luxury, Performance and Premium collections all feature bi-xenon HID units with signature vertically stacked LED running lamps. LED rear lighting is standard across the lineup, as are 18-inch alloy wheels wrapped in 225/40 all-season run-flat or regular tires.

The new ATS Coupe offers two sophisticated engines with direct injection and continuously variable valve timing, both also used in the sedan. The base 2.0-liter turbocharged 4-cylinder gets a boost bump for 2015 that will also benefit the sedan. While its horsepower carries at 272, torque rises by 13 percent to a heady 295 lb-ft -- 90 percent of which is on tap from just 2,100 rpm. Cadillac projects the revamped engine will let the ATS Coupe sprint from 0-60 mph in 5.6 seconds and will return 21 city/31 highway EPA numbers. The step-up alternative is the naturally aspirated 3.6-liter V6 that continues to make 321 horses and 275 lb-ft of peak twist while netting 19/28 mph EPA figures. Both engines are backed by a standard 6-speed automatic transmission, but the 2.0-liter turbo also can be paired with a 6-speed manual should the buyer choose.

Like the sedan, the ATS Coupe is based on GM's sophisticated Alpha platform and will be available in rear-wheel drive and optional all-wheel drive configurations. Here too, the crisply tuned and responsive FE2 conventional sport suspension includes StabiliTrak stability control and Brembo brakes, but can be upgraded to FE3 spec that brings driver-adjustable Magnetic Ride Control variable damping, a mechanical limited-slip differential, faster-ratio power steering and a high-capacity engine cooling system as well as staggered-width (225/40 front and 255/35 rear) 18-inch summer performance tires.

Sharing all of its basic styling cues with the sedan, the well-finished, well-appointed cabin the ATS Coupe features seating for four not five, although passenger space in the aft quarters does go well beyond typical 2+2 levels. Leather, aluminum, carbon fiber and real wood highlight the upscale character of this realm and a Bose premium audio system with Active Noise Cancellation helps eliminate unwanted road din while augmenting the actual sound of the engine. Optional on the base model but standard on all other ATS Coupes, Cadillac's CUE infotainment system benefits from several upgrades for 2015 including a new Text-to-Voice feature with Bluetooth profile and Siri Eyes Free that works with iPhone. The OnStar system also is enhanced with the availability of new 4G LTE connectivity and a built-in Wi-Fi hotspot. Other primo standard or optional features include a 12-speaker Bose audio upgrade, navigation system and head-up display.

Like the sedan, the ATS Coupe comes with a comprehensive array of safety features including eight air bags and carries a NHTSA 5-Star safety rating. It also offers Driver Awareness (Safety Alert Seat, Forward Collision Alert, Lane Departure Warning, Lane Keep Assist, Intellibeam high-beam control, front/rear park assist, rear-vision camera) and Driver Assist (full-speed-range adaptive cruise control, Automatic Collision Preparation, motorized safety belts, electronic park brake, Rear Cross-Traffic Alert, head-up display) packages.

The 2015 Cadillac ATS Coupe arrives in showrooms this summer. Pricing will be released closer to the actual on-sale date, but expect a starting price in the mid-$30,000 range.
