Which is fine. Why do we continue to compare the Challenger to the Camaro and Mustang? Those are pony cars - Challenger is muscle. Seats 5, weighs a lot more, more luxurious (gentleman's muscle car), etc. The fact that the 392, with an equivalent driver, shoud beat these other cars with an equivalent number of passenger (that are actually comfortable in the 392) is a good thing (and smoke them in a 1/2 mile). Yes, the 392 costs more - for the reasons already stated - but it can hang with smaller, lighter, uglier performance rides in style. The GT500 is faster, and soon the ZL1 will be out and will also be the faster ride - I don't care. I don't want either. The 392 is perfect (to me). If Chevy ever revived the Chevelle and Ford brought back the Gran Torino, then let's compare away...
That being said, I'm always happy to hear about 392's smoking other rides...
While I was responding to the OP, I agree completely. I went to test drive a Camaro and got inside and my head hit the ceiling. And I'm only 6'2". I put the power seat all the way down - my head still hit the ceiling. Forget wearing a helmet (a mandate at most tracks with a 13.99 or faster car). Test drive over. The 2011 Mustang is a far better car than the Camaro but it's still way too small inside for me and the family.
I honestly believe the Challenger SRT8 should be compared to larger luxo-performance import coupes like Aston Martin, BMW, Infiniti, Jaguar, MB, etc. because it really has no direct USA competition. Road & Track just made a similar observation about the 2011 Dodge Charger having no direct USA competitors and compared it directly and favorably to the BMW 550i. Similar features, almost identical size/weight, and similar performance.
While some might dismiss this as fanboy prattling, it's not a stretch to compare the SRT8 392 to coupes like the Aston Martin DB9, Jaguar XK, BMW 6 series, Infiniti G coupe, MB CL550. Look at the overall size, curb weight, features/specs, powertrain, chassis, suspension, brakes, wheels/tires, etc. The SRT8 392 is a luxo-performance coupe in the traditional Gran Turismo sense more than anything else.
This video pretty much sums up why I chose the SRT8 392. Note the comment about the GT500 being 'terrifying' on the same exact stretch of road (likely due to the ultra stiff suspension and live rear axle). The SRT8 392 is an American luxo-performance coupe designed for spirited driving in real world conditions and is not a smallish hard-core track weapon which will fatigue/scare the driver on real roads.
