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.

The biggest gas-guzzlers of 2024: 'The Meanest List' is the opposite of greenest cars

In some circles — especially some automotive circles — bigger is better. This explains the Hummer, for example. In its so-called “Meanest List” of a dozen models, the American Council for an Energy-Efficient Economy (ACEEE) makes no apologies for berating “the worst-performing mass market automobiles” sold in 2024 in the U.S. The most diminutive car on the list is a Chevy Corvette Z06. At the top of this particular heap is the Mercedes-Benz AMG G63, a gas-powered SUV that the environmental agency says was “the worst-performing vehicle of the more than 1,200 models assessed by Greener Cars and has an annual fuel cost over $4,000.” Not to mention its MSRP of around $184,000. Rank Make & Model Powertrain Green Score MSRP Estimated Annual Fuel Cost* 1 Mercedes-Benz AMG G63 Gas 20 $184,000 $4,242 2 Ram 1500 TRX 4x4 Gas 22 $98,335 $3,819 3 Ford F150 Raptor R Gas 24 $79,975 $3,777 4 Cadillac Escalade V Gas 26 $152,295 $3,388 5 Dodge Durango SRT Gas 26 $74,995 $3,332 6 Jeep Wrangler 4dr 4X4 Gas 27 $35,895 $3,260 7 Jeep Grand Wagoneer 4x4 Gas 28 $91,945 $3,058 8 Mercedes-Benz G550 Gas 28 $143,000 $3,186 9 GMC Hummer EV SUV EV 29 $98,845 $1,746 10 GMC Sierra Gas 29 $37,700 $3,069 11 Chevrolet Corvette Z06 Gas 30 $114,395 $3,169 12 Mercedes-Benz Maybach S680 Gas 30 $234,300 $3,031 *ACEEE analysis using EIA data of the annual cost of driving 15,000 miles In terms of numbers, the dirty dozen of the meanest includes seven SUVs and three trucks. Lonely at the middle of the list is the sole electric, the GMC Hummer EV, which weighs in at 9,000 pounds. The council notes that “though EVs have lower emissions than similarly sized gasoline models, the Hummer demonstrates that size and efficiency, not just fuel source, are important factors in a carÂ’s environmental impact.” ItÂ’s also worth reminding prospective buyers that the average fuel cost of a vehicle on the “Greenest List” eats up only a fifth of the fuel cost of a vehicle on the Meanest List, “showing that greener options can also be more affordable.” The ACEEE also put out a "Greener List" of efficient gasoline and hybrid cars that don't require plugging in.  By the Numbers Green Cadillac Chevrolet Dodge Ford GMC Hummer Jeep Maybach Mercedes-Benz RAM Emissions Fuel Efficiency Green Automakers Truck SUV Electric Hybrid
