As it currently stands, General Motors offers three vehicles based on its stretched Epsilon II platform, sometimes known as Super Epsilon, including the Buick LaCrosse, Cadillac XTS, and all-new 2014 Chevy Impala. With the three vehicles marketed as full-size luxury sedans, each is bigger than the average midsize sedan, albeit the Super Epsilon architecture has its roots in the midsize class with vehicles such as the Buick Regal/Opel Insignia plus the Chevy Malibu, and all three offer the 3.6 liter V6 LFX engine as standard or optional equipment.
Even so, each car is different in its own right in terms of exterior and interior styling, the image it conveys upon its driver and passengers, as well as the associated price tag. So the question is, which flavor of GM’s Super Epsilon do you prefer?
Take a look at our brief overview of each vehicle below, where we did our best to pick the most comparable equipment levels across the range, and then vote in the poll.
