When the 2013 Cadillac ATS launches in the next couple of months, it will have an official curb weight of 3,315 pounds (1,503.7 kilograms) when equipped with the 2.5 liter Ecotec engine and six-speed automatic gearbox — making it the lightest vehicle in the U.S. sports-compact luxury segment consisting of the BMW 3-Series, Mercedes-Benz C-Class and Audi A4. But the good news doesn’t end there, as the model powered by the 3.6 liter LFX V6 and six-speed auto will also be the lightest in its class, weighing in at 3,461 lbs (1,573 kg) and being able to achieve 60 MPH from a standstill in a short 5.4 seconds.

The light weight of the ATS equips it with quickness and agility — key characteristics of the segment. These defining qualities will also be complemented by slippery aerodynamics that result in a GM-estimated fuel economy of 32 MPG highway and 22 MPG city for the 2.5L and 2.0L turbo (EPA estimates are not available at time of publication).
Part of the way in which the ATS achieves its weight advantage is by using an aluminum hood and front suspension parts, magnesium engine mount brackets, as well as natural-fiber door trim panels. The engineering team, which — according to GM — counted grams rather than kilograms during the car’s development, also reduced weight in the rear suspension by implementing specially-engineering straight steel links with mass-reducing holes instead of utilizing aluminum.
The light weight, coupled with the ATS’ near-perfect 50-50 weight distribution, should make for one refined driving experience — and we can’t wait to get behind the wheel of one of these babies in the near future. In the meantime, all we can do is configure Caddy’s newest sedan to our heart’s content.
The GM Authority Take
It always helps to start with a clean slate, as Caddy did with the ATS. By doing so, decisions could be made early on to do things right — rather than shoehorn and eliminate features at some point along the vehicle’s development. We, however, wonder about the stats of the ATS cradling the 2.0 liter turbo engine, which haven’t been released yet.And while the ATS doesn’t disappoint in the 0-60 department, every auto enthusiast undoubtedly understands that these vehicles are much more than straight-line acceleration.
Looks like Karl-Friedrich Stracke — in his role as GM’s VP of vehicle engineering — wasn’t just spouting hot air, after all, when he said that Cadillac will beat BMW on unsprung weight. Kudos!Google+
