According to Automotive News, the next Impala will be based on GM's updated Epsilon platform - the very same that will underpin Cadillac's upcoming XTS sedan. Given the size of the XTS concept, it seems safe to assume that the next Impala will be larger than the car currently for sale on dealer lots.
The XTS will receive its power from GM's 3.6L direct-injected V6, and that powertrain also appears likely for the next Impala. In fact, the 2012 version of the big sedan will be updated with the 3.6L motor. The XTS was also shown with all-wheel drive, meaning it's at least possible the Impala could receive a similar system. Some form of a hybrid powertrain -whether mild or plug-in -- is almost a certainty.
The Impala currently overlaps the smaller Malibu in terms of price, but that won't be the case for the next-gen car. Like Ford's strategy with the Taurus and Fusion, the Impala will be marketed as a more premium vehicle than the Malibu - both in terms of size and price.
Look for production of the new Impala to begin in late 2012, with sales kicking off in early 2013 as a 2014 model.
