Every review over the years shows the Maxima, Impala, Passat, and Avalon as competitors. Sometimes Lacrosse, and Volvo S60
The 2016 bears little in common to the previous versions. The CVT is all new and it's nothing like the past. IMO, the only direct competitor is the V6 FWD TLX. Impala, Avalon and Lacrosse are similar.
