Two Fours and a Six: Cadillac Announces ATS Engines, including V-6, Turbo I-4

The Cadillac ATS is joining the ranks of the SRX crossover and upcoming XTS sedan as another Caddy that won’t be offered with a V-8 engine: Cadillac announced the full engine lineup for the car today, which includes two four-cylinder engines and a V-6.

The base engine will be a naturally aspirated 2.5-liter I-4 engine. While GM hasn’t released any formal specifications, it appears that this is the same 2.5-liter engine from the 2013 Chevrolet Malibu, which is estimated to make 190 horsepower and 180 pound-feet of torque.

The next step up is a 2.0-liter turbocharged I-4. It’s important to note that this isn’t the same motor as the one under the hood of the Buick Regal Turbo and GS, instead an all-new engine that will produce about 270 horsepower and 260 pound-feet of torque. It’s the first in a line of new Ecotec engines, and gets an electronically controlled twin-scroll turbocharger to keep its torque curve flat. The ATS will be the first car to feature this engine, although it will eventually move to the Chevrolet Malibu as well.

For ATS drivers who want to live a bit larger, Cadillac offers one more choice, and it’s a familiar one: a 3.6-liter direct-injected V-6. It’s the same engine that’s featured in the CTS and SRX models, as well as the upcoming XTS sedan. That engine makes 318 horsepower and 275 pound-feet of torque under the hood of the CTS sedan, although it makes marginally less in the SRX.

If there’s one thing missing, it’s a mention of the phantom ATS-V sedan, something that’s been bandied about over the past few months. Predictably, GM is mum on if the car will exist, but that shouldn’t stop fans of V-badged Caddies from holding their collective breath.
