General Motors is expanding the number of vehicles using its direct-injection 3.6-liter V-6 for 2012, although the two latest applications couldn’t be any more different.

First up, Cadillac announced that the 2012 SRX crossover will arrive in dealerships later this year with the 3.6-liter V-6 as its sole engine offering, replacing the model’s current 3.0-liter DI V-6. Final figures for the SRX-tuned V-6 have yet to be finalized, but we’re told the engine will produce “at least” 300 horsepower and 260 pound-feet of torque. The outgoing 3.0-liter engine made 265 horsepower and 223 pound-feet, which made for competent but hardly spirited performance.

The Caddy’s engine swap doesn’t come as a big surprise, having been predicted earlier this year. Cadillac also dropped the unloved turbocharged 2.8-liter V-6 engine from the SRX spec sheet in January (it had a paltry take rate of less than 10 percent). The old V-6 will live on in some foreign markets, like China, where SRX buyers will have a choice of both the 3.0-liter and 3.6-liter engines.

Also discovered (but not publically announced) this morning is that the aging 2012 Chevrolet Impala will also be powered only by the direct-injection 3.6-liter V-6, although the engine will be tuned to deliver only 287 horsepower and 258 pound-feet of torque. Still, those figures beat both the 211-horsepower 3.5-liter and 230-horsepoewr 3.9-liter V-6s previously offered.

The larger, direct-injected V-6 sees duty in a range of other General Motors vehicles, including the Cadillac CTS and Chevrolet Camaro. Fuel-economy figures for either the 2012 SRX or Impala haven’t yet been determined, but Cadillac tells us the 2012 SRX should offer numbers comparable to the 2011 SRX’s of 18/25 mpg (city/highway) rating. Pricing for the 2012 SRX will be announced closer to the on-sale date, which is later this summer.
