As part of efforts to comply with the new Corporate Average Fuel Economy (CAFÉ) legislation, General Motors is determined to physically downsize its product lineup. GM has been forced to make vital decisions about its future midsize sedans as the new laws will take effect in 2012 through 2016. GM has plans to shift to more fuel efficient vehicles.
Sources, who worked on the next-generation GM midsize sedans, said that GM has chosen to proceed with an all four-cylinder engine lineup for each midsize sedan. This change was evident on the recently launched 2011 Buick Regal, which offers two four-cylinder engine options.
In addition, the upcoming Regal GS performance model will be directing a four-cylinder mill. Sources said that these efforts will be observed in the next-generation Chevrolet Malibu, which is set to launch in late 2011.
The new Malibu will only offer four-cylinder engines in North America. It has yet to be confirmed what type of four-cylinder mills GM will place in the Malibu.
However, the direct injected 2.4-liter from the Equinox is expected to rival the new offering. GM is focusing on new four-cylinder engines—both turbo and naturally aspirated—including a non-turbo 2.5-liter.
Meanwhile, products on the larger side of GM’s midsize sedan lineup will require optional V6 power, including the next Chevrolet Impala. [via GMInsideNews]
