I think if Viper owners voiced our opinions in a poll you would find that, yes we all want a coupe as another body style option, some of us like stripes, and no one would deny that more colors would be nice. All of this would do nothing to the performance / refinement of the car itself.
42V electrical system. Interesting. Toyota, Honda, BMW, Mercedes etc. are all working on this, but the change over is more than a few years away. I don't agree that a much more efficient electrical system is going to eliminate the GGT! The 42V system will come to all cars in time, including the Viper but since Conner Ave isn't exactly area 51, don't hold your breath. I don't have a pre-occupation with HUDs, I just listed a lot of Vette features that don't help the car go faster or handle better. Race cars don't have speedometers. I see a huge difference between 'real' race cars and Formula 1. When they started adding all the electronic crap, it started to take away from driver control. To the point where a computer launches the car. (driver skill no longer needed for that) Skid and stability controls are a nice safety feature on street cars, but I think are too much on a track. Nascar doesn't have it. If they win a race, it was the pure skill of the human, not the machine. That's exactly my whole point in this debate. There are cars for comfort (745Li) and some for efficiency (Prius) , and some for space (Excursion) and others with mind numbing electronic brains (745Li)! I want the minimum in my sports car. Nothing extra that adds weight. Look at the AMG SL55. It weighs over 4000 lbs! It is almost as fast as a Viper, makes the same horsepower and torque and is VERY refined and comfortable (and expensive). They took a good basic design and added and added and added. It pampers and coddles and does everthing but say "good morning captain" when you get in. Nice for it's purpose, made by the same company as the Viper, but low on the adrenaline rush scale.
Hydroformed frame rails? Do you think the SRT structure is weak? OK, if it made the car lighter, fine. Speaking from experience, this thing is tight! I can hit the big potholes and there's no evidence of cowl shake. With a suspension this tight, it's incredible and far superior to my previous RT-10. I drove my brother-in-laws 2002 Vette (hatch) with the targa roof off and noticed a slight quiver in the windshield. The hydroformed Vette convertible weighs within 100lbs of the snake. (3349 vs. 3250 if not the exact figures forgive me) Only the Z06 has been given the 'stripper' config. I hope an SRT coupe weighs a good deal less than the convertible.
I gotta go re-read the refinements you listed, back in a sec.
