While the biggest news this year is the SRT Hellcat and its 707-horsepower supercharged V8 engine, the reality is that every 2015 Dodge Challenger benefits from significant upgrades. The standard-issue...
... automatic transmission is now the excellent 8-speed we've enjoyed in the
Chrysler 300. Here, it helps even the V6 SXT achieve new performance heights. But let's be honest: The Hellcat is the one everyone's talking about. Its prodigious power makes the tremendous acceleration nearly impossible to explore on busy public roads. It has a stiff highway ride, but it's no worse than, say, a Corvette. At a steady cruise the engine noise is subdued, with the supercharger whine a companion only as revs rise. Put the Hellcat and non-supercharged SRT Challengers into Track mode, and they transform with sharper throttle response, harder shifts from the automatic transmission, and stiffer shocks. Yup, this big boy can move.
