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.

Watch Atieva's electric van outrun a BMW i8 and Dodge Viper

A little while back, automotive startup Atieva drag raced its electric van, called Edna, against a Tesla Model S and a Ferrari California in order to compare its performance against known and revered mechanical athletes. Again, the Silicon Valley-based company is putting its prototype up against electrified and conventionally powered performance vehicles on the drag strip. Last time around, Edna, the Mercedes-Benz Vito van equipped with a 900-horsepower, all-wheel-drive powertrain, bested both of its foes. In that showcase, Edna was hitting 60 mph in a little over three seconds. Comparatively, BMW lists the i8's 0-60 time at 4.2 seconds, though Road & Track clocked it at 3.8 seconds, with a quarter-mile time of 12.3 seconds. The Viper does 0-60 in 3.4 seconds. Before you even watch the video above, you can imagine how it will end, as the retuned Atieva Edna rips 0-60 mph in 2.94 seconds. Atieva clocked the quarter mile at 11.3 seconds at 117 mph. It's worth noting that driver skill can have a lot to do with a car's straight-line performance. We've witnessed Viper's elapsing the quarter mile in well under 12 seconds, which means it should be quicker in this test than the i8, if not the Edna. Still, the performance showcased in the video is exceptional. To improve Edna's stats, Atieva says it has used testing data to fine tune its AC induction motors at higher speeds once it got low-speed performance locked in. After testing in the hot California sun, including the race you see above, Atieva drove Edna 90 miles home with range to spare. As for production plans, Atieva will put this powertrain into a sedan slated for sale in 2018. In the meantime, the company will keep testing and tuning its working prototype, and has even invited the public to put their cars up against Edna in future sessions.

Dodge Charger Hellcat makes 1,032 hp with Hennessey help

Sometimes you just want four doors. Earlier this week we brought you Hennessey's riff on the Dodge Challenger Hellcat. Now comes the Charger. Much like its two-door sibling, the Charger gets boosted to as much as 1,032 hp and 987 lb-ft of torque (at the crank) thanks to the addition of a twin-turbocharging setup that works with the factory supercharger. The turbo headers and downpipes are stainless steel, and there is a high-flow air-to-water intercooler and dual-turbo waste gates. Hennessey also beefs up the fuel injectors, fuel pump, and the rest of the fuel system. The engine management system and chassis are recalibrated to accommodate all of this. You also get numbered plaques signed by John Hennessey, the boss of the Texas tuning outfit, and the technician who does your build. Hennessey's additions result in zero-to-60 mph sprints in 2.7 seconds, and the big sedan can run the quarter mile in 9.9 seconds at 142 mph. Like the Challenger, the Charger has the same disclaimer: the lofty horsepower figure comes from an engine dyno, and it will be a 15-to 20-percent lower at the rear wheels.
