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.

Daily Driver: 2015 Dodge Charger SRT Hellcat

Daily Driver videos are micro-reviews of vehicles in the Autoblog press fleet, reviewed by the staffers who drive them every day. Today's Daily Driver features the 2015 Dodge Charger SRT Hellcat, reviewed by Greg Migliore. You can watch the video above or read a transcript below. Watch more Autoblog videos at /videos. VIDEO TRANSCRIPT: [00:00:00] Hey, everybody. It's Greg Migliore and today I am driving a 707-horsepower Dodge Charger. That can only mean one thing: I'm driving the Hellcat. Naturally, the spotlight feature of this car is the 6.2-liter supercharged Hemi V8. Makes 707 horsepower and 650 pound feet of torque. [00:00:30] Now naturally the engine sounds great and you can hear all of those horses going out the exhaust in back, which I think the Dodge guys have tuned really well. I think it's got one of the more unique sounds in the industry. All that horsepower will do that, but they've tuned it so there's a low kind of growl, and then it burbles and it's angry [00:01:00], it's visceral. I like it. It's intoxicating. It's different than other muscle cars. It's different than European exotics. I think it sounds great. I'm driving in sport right now which allows me to use the paddle shifters. I think it sounds a little better and the shifts of the eight-speed automatic transmission are a little bit more aggressive. For such a powerful car, Dodge did a nice job of tuning it to be actually pretty drivable. I just took a corner right there and the [00:01:30] steering offers you satisfying weight to your inputs. It's a little bit of a heavier steering, especially compared to some of the earlier generation Chargers. It's sporty, but it's not crazy. The design of the Dodge Charger is a critical element. That's why a lot of people buy this car, is it gives them that muscle car heritage look. The Hellcat has some special design cues that are also functional. You've got a couple of extra air intakes up front, keeps everything cool and breathing, the air flowing through; a nice spoiler in back [00:02:00] that helps keep the aero, and the downforce keeps you on the ground. The HID projector headlights really pop, especially at night, and in back you've got the LED taillights that spread out wide across the back end of this car like some of the great Chargers of the past. This car rolls on 20-inch black wheels with a spiderweb design. I think they look good. They're kind of low-key, which I think is great.

2015 Dodge Viper getting small increase in power

The Viper is used to being the most powerful car in the Dodge and SRT stables, but the arrival of the 2015 Dodge Challenger SRT Hellcat means that's no longer the case. The serpentine supercar is, however, reportedly getting a small boost in output for 2015, amounting to all of five horsepower.
The increase was uncovered by Road & Track courtesy of the SAE J1349 certification process to which Detroit's Big Three automakers submit themselves and which reports the Viper's output at 645 hp instead of the 640 it was rated at until now. There are a hundred factors that could have contributed to the relatively mild boost in output (best guess? nothing at all changed...), but we doubt anyone's going to complain about some extra horses under the hood.
The five-horsepower boost brings the Viper that much closer to the 650-hp Chevy Corvette Z06, not to mention the 707-hp Hellcat, but the Viper's impressive power-to-weight ratio ought to mean it'll have little problem keeping up in a straight line - which is just one of the reasons why Chrysler won't shoe-horn the Hellcat into the Viper: as R&T points out, the supercharged engine is too heavy and the blower makes it too tall to fit in the Viper's engine bay.
