GM to Replace 2.4-liter Fours with 2.5-liters Across the Range

via Car and Driver Blog by Justin Berkowitz on 1/10/12

General Motors will upgrade one of its workhorse four-cylinder engines. The news comes straight from GM's North American president Mark Reuss at this year's Detroit auto show. The 2.4-liter four—which currently does duty in the Chevy Equinox, Buick's Verano and Regal, and the GMC Terrain—will hit the road; it's replaced with a new, direct-injected 2.5-liter inline-four.
The new engine will debut in the 2013 Chevy Malibu with slightly north of 190 hp and 180 lb-ft of torque, and we expect it to offer similar power in other applications. This will be a nice bump from what the 2.4-liter engine offers today: 169 hp with port injection and 182 hp from the direct-injected version.
The change will be applied across GM's U.S. range, with the switchover taking place within the next 12 months. GM hasn't yet confirmed whether the 2.4-liter engine used in its EcoAssist hybrids will remain in use, or if the 2.5 will be adapted to do service there.
