Having driven the 2011 R/T for most of the year, I was already familiar with most of the features but was completely unprepared for the improvement in handling and power this beast brings to the table.
On a highway you can easily top 100 mph without the pedal getting halfway down and still be treated to a symphony from the engine, which prompted an unprintable exclamation of approval from my first passenger. The auto mode sets the suspension for maximum comfort and in even the sharpest turns the car remains level. Sport mode unleashes the car's max performance.
Fuel economy is about the same as I had with the R/T, although thats more due to San Diego traffic than anything else.
I'm a guy who likes his gadgets and the Uconnect system alone makes me feel like i'm in a James Bond car. Combining radio (satellite and terrestrial), navigation (with an added feature for traffic reporting and avoidance), finding movie schedules/football games/the cheapest gasoline (and directions to each) pays dividends over and over.
New this year is the performance display which lets you see your 0-60 type stats, g-forces acting on the car, even how much hp and torque you're using.
Heated seats (including the back seats), steering wheel, vented seats and my personal favorite - the cupholders; if only because I need a drink kept cold more often than any other feature.
The Engineers on the SRT team really outdid themselves with this fine piece of machinery. I'm quite giddy in anticipation of the reported Supercharger that could be added to the engine next year.
Not much more you can do to make this car better, short of:
-Excempting drivers from traffic laws
-Adding weapons to minimize other traffic/obstructions
