2014 Cadillac ATS and ATS-V Spec Sheet Makes the Internet Rounds, but is it Real?

A supposedly official preliminary spec sheet of Cadillac's forthcoming new small luxury sedan surfaced on the internet today. We're not going to call it a leak just yet as we're not at all certain for its authenticity. That said, we'd advise you not to take anything you read on the paper after the jump for granted.

Labeled as the 2014 Cadillac ATS, the spec sheet says the Detroit firm's BMW 3-Series rival will be offered with three engine options including a 270HP 2.0-liter turbocharged four-banger and a 330HP 3.6-liter V6 for the standard versions, and a 470HP 6.2-liter V8 for the M3-challenging ATS-V. The four-and six-cylinder models are said to be hooked up to an 8-speed automatic transmission, while the flagship V8 comes with a 6-speed auto.

While we can't vouch for the numbers and data shown on the spec sheet, we can tell you that the ATS, or whatever else GM decides to name its new entry-level sedan, is expected to hit the market within the next two years.

New Cadillac CTS-V Coupe Racer Hits the Tarmac for the First Time

Cadillac is getting ready to return to the fabulous world of motorsports with its new CTS-V Coupe race car. Following the two-door model's world premiere at the Detroit Motor Show last week, the race-prepped CTS-V Coupe hit the track for the first time on Monday driven by Johnny O’Connell and Andy Pilgrim, for tests at Sebring International Raceway.

GM's luxury car division had pulled out of racing before the U.S. government bailed out the company in 2009. More specifically, the last time Cadillac competed was in 2007 in the Sports Car Club of America World Challenge GT series. Now, the company will reenter the series, beginning with the season-opening race in St. Petersburg, Florida on March 25-27. Hit the jump for a comprehensive gallery.

GM Recalling More than 26,000 Cadillac, Chevrolet and GMC SUVs and Trucks

General Motors is expanding a previous recall concerning a faulty rear-axle cross pin to include another 26,751 SUVs and trucks from the 2011 model year. The first recall was issued in late December and concerned approximately 1,260 Cadillac Escalades, Chevrolet Avalanche and Silverado 1500s, and GMC Sierra 1500s, all from the 2011MY.

The updated recall now covers certain 2011MY Cadillac Escalade, Escalade ESV, Escalade EXT; Chevrolet Avalanche, Colorado, Silverado, Suburban, Tahoe; and GMC Canyon, Sierra, Yukon and Yukon XL vehicles.

The Detroit automaker said the rear axle cross pins were not properly heat treated and could fracture and become displaced within the rear axle.

"Should the pin shift out of position, it could create an interference condition and cause the rear axle to lock. The driver may not be able to maintain directional control of the vehicle and a crash could occur without warning," said GM in a statement on NHTSA's website.

As expected, GM's dealers will install a new rear axle cross pin free of charge, with the safety recall to begin before the end of the month
