Mopar unveils Dodge Challenger Drag Pak [w/video]

Dodge is going drag racing, and it's doing it with an all-new version of the Challenger for NHRA's Sportsman class. FCA's Mopar parts and performance arm announced the new Challenger Drag Pak Friday, showing off a version with a 354-cubic-inch (that's a 5.8-liter, by the way), supercharged V8 and a 426-ci (7.0-liter), naturally aspirated V8 – both Hemis, of course – that can get the big coupes through the quarter-mile in "the eight-second range." While the two engines deliver similar performance, at their base, they're quite a bit different. The supercharged model uses a cast-iron block, while the 426 has aluminum for both the block and head. That said, both models get customized engine calibrations, and are mated to unique, race-spec automatic transmissions. But drag racing is about far more than just outright power. Mopar significantly updated the four-link rear suspension, adding a four-inch rear axle from Strange Engineering, along with an aluminum, nine-inch third member, while the rear-axle housing has been strengthened in general. Both the rear shocks and front struts can be adjusted for rebound and compression, too. Lightweight 15-inch wheels, meanwhile, are shod in super-sticky Hoosier drag radials, with nine inches of tread in back and 4.5 inches in front. The new Challenger Drag Pak should run the quarter-mile in "the eight-second range." In the cabin, there's an NHRA-spec roll cage, a Racepak gauge cluster, and a handsome pair of Sparco racing seats. Outside, supercharged models get blue decals, while naturally aspirated varieties get black stickers, although there's more to the new Challenger dragster's exterior than just its decals. Mopar tweaked the big-scoop hood, promising it's easier to get up to check on the engine, and the designers also added trailer tie-down straps in both the front and rear. While the dragster was the big news today, Mopar officials also announced the two enhanced Scat Pack kits for both the Dodge Charger and Challenger R/T. The 5.7-liter Hemi models gain an extra 56 horsepower and 30 pound-feet of torque in the Scat Pack 2 thanks to a new cam, valve springs, pushrods, and gaskets. The Scat Pack 3, meanwhile, adds 75 hp and 44 lb-ft, on top of the gains from the lower packages. That should be perfect for drivers who wish to snort in the face of their SRT 392-driving friends. The third stage adds a ported cylinder heads, as well as high-flow manifolds and catalysts.

Jay Leno drives a 1970 Dodge Charger with 1,650 horsepower

When Jay Leno says a vehicle might have too much horsepower, he's got our attention piqued. That's exactly what he thinks about the 1970 Dodge Charger Tantrum from Wisconsin-based SpeedKore Performance. While it still looks like a classic muscle car, the front end now features a carbon fiber hood and fenders. Underneath the lightweight parts, there's a twin-turbo, 9.0-liter Mercury Marine offshore boat racing engine with an astonishing 1,650 horsepower, or an only slightly less asinine 1,350 hp on pump gas. Jay is very mechanically intrigued by the Charger at the beginning of this video, and puts it on the lift to take a look at the underside. The engine plumbing is a thing of beauty, and the mill packs a massive radiator and intercooler to keep things running cool. Leno's drive in the Tantrum is especially interesting. The beastly engine is difficult to control, and anything above half throttle in most gears can spin the rear tires. The significant turbo lag also makes the power unpredictable. When Jay finally finds a straight piece of road, he puts the hammer down and rockets into the distance. And, of course, you know Jay's not going to end the video without some suitably smoking tires.

Performance doesn't matter anymore, it's all about the feel

We've just had a week of supercars and high-end EVs revealed. Many of them boast outrageous performance specs. There were multiple vehicles with horsepower in the four-figure range, and not just sports cars, but SUVs with 0-60 mph times under 3.5 seconds. And it's not just a rarified set of supercar builders, comparatively small tuners are also building this stuff. Going fast is easy nowadays and getting easier. So what will distinguish the greats from the wannabes? It's all about how a car feels. This may seem obvious. "Of course it matters that a car should have good steering feel and a playful chassis!" you say. "Why are you being paid for this stuff?" But a lot of automakers have missed the memo. This past week I spent some time in a BMW M4 Competition convertible, and it's a perfect example of prioritizing performance over experience. It boggles my mind how a company can create such dead and disconnected steering; the weight never changes, there's no feel whatsoever. The chassis is inflappable, but to a fault, because it doesn't feel like anything you're doing is difficult or exciting. The car is astoundingly fast and capable, but it feels less like driving a car and more like tapping in a heading on the Enterprise-D. I also happened to drive something of comparable performance that was much more enjoyable: a Mercedes-AMG GT. It was a basic model with the Stealth Edition blackout package, and even though it had a twin-turbo V8 instead of a six-cylinder, it only made 20 more horsepower. The power wasn't the big differentiator, it was (say it with me) the feel. While not the best example, the steering builds resistance as you dial in lock, giving you a better idea of what's happening up front. Pulses and vibrations come back to you as you move over bumpy pavement in corners. The chassis isn't quite as buttoned down, either, providing a little bit of body roll that tells you you're pushing it. It's also easier to feel when the car is wanting to understeer or oversteer, and how your throttle and steering inputs are affecting it. The whole thing is much more involving, exciting and fun. 2021 Mercedes-AMG GT Stealth Edition View 8 Photos That's also to say nothing of the Merc's sounds. That V8 is maybe not the best sounding engine, but its urgent churn through the opened-up exhaust gets your heart racing. It also seems like it's vibrating the whole cabin, so you feel it as much as you hear it.
