The Interceptor has the 3.7 n/a. It runs pretty decent but lacks the low end torque of the Sport. It has a column shifter as the console has our radios and controls for lights/siren. It has 18in wheels and a bench seat in the back(no 3rd row). The instrument cluster is analog vs the 2 displays and the speedometer on the sport. This one is a 2013 and we just got a 2014 about 6 months ago.
The sport has 402a, moonroof, 2nd row buckets, tow package, adaptive cruise, and is working out really well so far with our 3 kids and us. Right now it is averaging 18.2 mpg(mostly city driving). I might do a Livernois tune after the warranty is gone.
