This is the second generation of the SRT8 twins, but this time the Dodge came out first, then the Chrysler. The 6.4-liter Apache motor is essentially an updated 6.1-liter ESF, with a little bit of improvement on the bore and a significant improvement on the stroke, allowing for extra cardio (power) and muscle (torque).
Although the computed 0-60 time is technically the same as the earlier SRT8 (and the figure-8 track time is even slower by 1.1 seconds) due to ill traction and nose-heavy weight struggles, the later one is estimated to be faster in every other aspect, including the Nurburgring Nordschleife and the Top Gear Test Track.
