I'm a simple man, so I'm still struggling with the summary dismissal of the Viper/Cobra as vehicles worthy of consideration -- unless what is really being conveyed is a distaste for American cars and the American men who buy them.
Yes -- the way in which both cars went about their business was quintessentially American, but I mean that in the best possible way. Neither was fussy or delicate or laden with a bunch of frippery. Both demanded skill from their driver. If that skill was lacking, the cars didn't have a lot of mercy. They weren't about making a driver look better than he was. The Cobra was 1960s Shelby, the Viper was the latterday version of Carroll's vision.
The Viper was not unlike another V10 brute that came out about the same time, although the other one is Jacob and this one is Esau. The weird part is how we (on this site) love one and hate the other, even though they are like twins separated at birth -- two sides of the same coin. Somehow, we've come to the point of worshiping the Porsche Carrera GT and despising the Dodge Viper SRT10. One required that the operator be a driver, and the other was... um... too much. Yeah! That's the ticket! The Viper was "too much" and the Carrera GT was a driver's car, although I would imagine the distinction would be lost on Paul Walker.
The Viper was a front-engined 2-seat V10 race-car for the street. Versions of it won at both Daytona and LeMans. It had ABS because it needed to have ABS to be legal, but there was none of the whizbangery nonsense that we all claim we don't like in modern automobiles. Compared to a modern PDK-equipped German car, it was almost breathtakingly analog. No electronic turbos, no vector braking, no electronic googaws to enhance one's abilities. It's been panned for being "crude" by the same guys looking for an "unfiltered" sportscar experience. That seems really odd to me.
Was it a "sportscar"? Probably not, since it weighed 3400 lbs and had 500 hp and was competing with supercars (with about the same weight and about the same power) costing 4x as much at the time. But I'd proffer that if weight is the prime consideration: given modern crash standards, there are no legitimate European sportscars left at all. The only cars that kinda' meet the criteria are Japanese: the MX5 and the BRZ/GR86. These cars (rightly or wrongly) are panned for being underpowered. Either way, an MX5 weighs 2300+ lbs and a BRZ is 500 lbs heavier.
Danny was working in big, round numbers, but he's got a 1500 lb car with 200 hp and ideal weight distribution. That's 7-1/2 hp for every pound of curb weight. I can tell you from experience, that this is nearly ideal for mountain road work. It's brutal and strong. If a 2000 lb car were similar, it would need 266 hp. For a 2500 lb car, that number is 333 hp (which is pretty close to stock 15 y/o Ford Coyote 5.0 power). We're a long, long way from that with most Speedsters.
I'm not sure what the magic number is supposed to be, but if a Cobra can be within 500 lbs of a speedster, I'm lost why it's thought of as the inferior machine. It's got a modern front end, can be had with IRS in the back, and has 2-3x the power under the hood. The weight distribution is not ideal, but neither is it a speedster.
Is all that needed? Probably not -- but I'm not inclined to be disrespectful of something that can spank my pride-n-joy hard. I realize I'm just an overgrown hicktown white-trash wannabe boy-racer who happened to be shown how to rub two nickels together, but a broadsword was a pretty effective weapon.
As I said, I like driving a slow car fast, and I like fighting the fight with Mighty Mouse, even if I do look like a Shriner in a clown car. But the fight I'm fighting better be on tight mountain roads and not out on the 2-lane blacktops that constitute most of America, or my little 180-200 hp (ish) 2.3L four-banger is going to be beaten up, have its lunch money taken away, and beaten up again. More power would make it more better, assuming I could get a 230 hp lawnmower engine to hold together long enough to even get to the mountains on something that doesn't have a winch or hook attached.
They're particular cars for particular functions. A more powerful car has a wider bandwidth. Your mileage may vary.
