VIDEO: 2014 Cadillac ATS Compact RWD Sports Sedan Spied Out Testing

A prototype version of Cadillac’s upcoming BMW 3-Series and Mercedes-Benz C-Class rival, dubbed the ATS, has been caught on video during road testing. Though still heavily camouflaged, it appears that the Detroit firm’s compact, rear-wheel drive sports sedan will continue with Cadillac’s Art and Science design language.

The new ATS sedan will be positioned below the CTS, taking its place as the Cadillac’s entry-level model. The introduction of the ATS will allow the next iteration of the CTS to grow in dimensions to better compete with Germany’s executive saloons like the BMW 5-Series and Audi A6.

The engine lineup of the ATS is pretty much speculation as of right now, though a supposedly official document that leaked onto the internet in January made word of three engine choices including a 270HP 2.0-liter turbocharged four-cylinder, a 330HP 3.6-liter V6 and a 470HP 6.2-liter V8 for the range topping ATS-V.

VIDEO: Hennessey’s Cadillac CTS-V Sport Wagon vs Nissan GT-R and Porsche 911 Turbo

American tuning firm Hennessey has crafted some pretty insane vehicles over the years. One of its most recent tunes is based on the Cadillac CTS-V Sport Wagon, which leaves GM’s factory with a 556-horsepower 6.2-liter V8 lump, but once Hennessey’s engineers perform their magic under the hood, output is lifted to 650 horsepower.

To show off the tuned CTS-V Sport Wagon’s potential, the Texas-based company brought the Cadillac to the track and drag raced it first against a stock 480HP Porsche 911 Turbo [997] and then a standard 485HP 2011 Nissan GT-R. Watch what happened in the video after the jump.
