| It’s been almost four decades since we’ve seen a new Dodge Challenger, and in the intervening years there have been a few changes. Okay, if you want to be picky, the last car to be called a Challenger disappeared from the Dodge lineup in 1983. However, that Challenger, introduced in 1978, was an anemic little four-banger made by Mitsubishi, capable of 0-to-60 mph in 13.6 seconds and the quarter-mile in 19.1 at 71 mph. That kind of performance might challenge guys on skateboards, but it looked pretty pathetic compared with real Challengers, such as the one we’d tested eight years earlier.
Like the new SRT8, the visiting 1970 Challenger had a Hemi V-8, the original bad-boy 426, rated at 425 horsepower and 490 pound-feet of torque, despite insurance-company flak. The Hemi and the less-powerful 440 Challengers were no lightweights—our test car weighed 3890 pounds, 58.9 percent of it on the front wheels—but when the driver opened all the holes in the dual-quad carbs, it could get enough traction from its Goodyear Polyglas rear tires to cover the quarter-mile in 14.1 seconds at 103.2 mph.
The Hemi option was gone by 1972, and by 1974, the last year there were real Challengers in the Chrysler catalog, the hottest engine you could get was a 245-hp, 5.9-
liter V-8. The ersatz Mitsubishi Challengers showed up in 1978.
That brings us to now, and we mentioned changes. Most are predictable because the rides we revered during the golden years of the muscle-and-pony-car show are essentially antiques by contemporary standards. Sure, there was horsepower galore, but it propelled cars with brakes that faded quicker than a one-night romance, steering as vague as campaign promises, and tires with all the grip of a hog sprinting on a hockey rink.
Like any contemporary performance car, the SRT8 Challenger is infinitely more competent in all dynamic areas than its ancient ancestor. But there’s one change versus the original Challenger that’s subliminal: Its timing versus the competition.
In November 1969, we reported that the Challenger, a response to the Mustang phenomenon, was "easily three years too late" and, further, that "Chrysler doesn’t do anything first." Surprise: The latter-day Challenger will be in showrooms by the end of April, at least four months before the reincarnation of the Chevy Camaro, a developmental drag race that began when the two cars appeared as 2006 Detroit auto-show concepts.
"We wanted to be first," says Erich Heuschele, SRT manager of vehicle development. "But our big surprise was coming out with the performance version first. We figured no one would expect us to do that."
To be fair to Chevy, Chrysler didn’t have as far to go with its retro project. GM had to wait for a new platform from Holden, its Australian division. The Chrysler engineers only had to get out their heliarcs and shorten the LX platform (Dodge Charger, Chrysler 300), subtract a couple doors, and integrate the new sheetmetal. Oversimplification? Maybe, but Heuschele says development cars were rolling not long after the curtain came down on the ’06 show.
"We made some short-wheelbase mules from Chargers," he says. "We essentially chopped ’em in half, made custom short doors, shortened the body, painted the Brembo calipers black, and we’ve been driving ’em around for almost a year and a half.
"You could tell what they were if you looked close. The rear windows were smaller, and they were Lexan. But hardly anyone noticed."
Besides public roads, "driving ’em around" included a 24-hour durability run at the Nelson Ledges road-racing course last spring.
"We passed with flying colors," says Heuschele. "All we had to change were tires and brakes." |
