Straight from the "No Surprise" department comes word from GMInsideNews that all of General Motors mid-size offerings will come equipped with four-cylinder engines as the only available powerplant.

GM has made it clear for the last few years that a large part of its future product strategy is to downsize its engine line-up in preparation for the new 2015 CAFE standards. The shift has already begun with the introduction of the 2011 Buick Regal, available with either a 182-horsepower direct injected 2.4-liter or a turbocharged 2.0-liter putting out 220 hp and 258 pound-feet of torque.

The next model to go all-four-banger will be the next generation Chevrolet Malibu, slated to arrive late next year and likely packing – to begin with – the same 2.4-liter four. A range of direct injected engines, both naturally aspirated and turbocharged, are in the works, so the General won't be hurting for options, but expect the V6 to stick around for GM's larger offerings, including the next Impala.
