2015 Cadillac ATS Coupe revealed with Onstar 4G hotspot

Cadillac has unveiled the 2015 ATS Coupe, a compact luxury two-door based on the ATS sedan, and one of the first of the marque's cars to get "Connected by OnStar" 4G LTE integrated. Hitting showrooms this summer, the ATS Coupe will offer a choice of rear-wheel drive or all-wheel drive and two engines, for what Cadillac claims is a "distinctive American alternative" to the BMW 428i and other rivals.

First under the hood is the 2.0L turbocharged four-cylinder, the same as in the ATS sedan but massaged to put out around 14-percent more torque, at 295 lb-ft. 0-60mph is in an estimated 5.6 seconds, and it musters 272HP. As for the 3.6L V6, that gets 321HP and 275 lb-ft of torque. Each uses a six-speed auto, though a six-speed manual option is an option for the 2.0L engine.

On the outside, it's not quite as crisply distinctive as the Cadillac ELR, the company's range-extended hybrid, but it does carry over some of the sharpness of the sedan. The wheelbase is the same, but the roof, doors, rear fenders, and trunk lid are different, and it has a wider track and shorter overhangs. The wheels are 18-inch, and there's optional LED headlamps and optional illuminated door handles.

Under the metal, there's near-50/50 weight distribution, five-link independent rear suspension, multi-link double-pivot MacPherson-strut front suspension, and Brembo front brakes. FE3 sport suspension is an option, with the Magnetic Ride Control that has impressed us on previous Cadillacs.

Inside, there's Cadillac CUE with an 8-inch touchscreen, an optional 12-speaker audio system, 5.7-inch instrument panel display, USB/aux-in/SD ports, SiriusXM, and Bluetooth for phone calls and audio streaming. CUE also offers text-to-speech for reading out text messages; a higher-spec version of the standard Bose system tracks ambient and road noise and adjusts the audio levels and content to suit.

Meanwhile, the 2015 ATS Coupe will also be one of the first Cadillac cars to include the integrated AT&T LTE hotspot that Chevrolet announced last week. That can share a 4G connection between up to seven WiFi devices, as well as enable CUE Collection, the app store that will launch later in the year. There'll also be remote-start and other features from Cadillac's smartphone app.

Cadillac is yet to announce pricing for the 2015 ATS Coupe, which will go on sale this summer.
