NC dealer creates the convertible Challenger that Dodge won't build

Dodge still hasn't turned the Challenger into a convertible, and the odds of seeing a factory-built drop-top muscle car appear in showrooms are decreasing annually. Tired of waiting, a dealership in North Carolina teamed up with a Florida-based body shop to create a topless alternative to the Ford Mustang and the Chevrolet Camaro. It's the real thing, and it's for sale. Keffer Dodge, Chrysler, Ram and Jeep shipped three 2019 Challengers to a shop named Convertible Builders, according to Motor Authority. After losing their lid, they gained a cloth soft top that opens and closes at the push of a button. There's no word on what effect the conversion has on handling, or what Convertible Builders did to offset the loss of structural rigidity. The build didn't include mechanical modifications. Two of the convertibles are R/T Scat Pack models equipped with a 6.4-liter Hemi V8 engine that serves 485 horsepower and 475 pound-feet of torque. It's not a supercharged Hellcat V8, but it's potent enough to spin the rear wheels in third gear. The third, R/T-based model features a 375-horsepower, 5.7-liter V8. While our dream build would use a six-speed manual transmission, all three come with an eight-speed automatic that sends the engine's power to the rear wheels. Keffer's website lists the gray, white, and red cars at $64,000, $60,000, and $56,300, respectively. The regular R/T Scat Pack Widebody model starts at $46,245, and the eight-speed automatic adds another $1,595, so the convertible conversion adds about $16,000. It's your only option, unless you're brave enough to chop the top yourself, or patient enough to wait until the early 2020s. Dodge has already started developing the next-generation Challenger, so the current car is unlikely to spawn a convertible before it retires. Its replacement due out in 2021 or 2022 will allegedly ride on a wider, longer evolution of the Giorgio platform found under the Alfa Romeo Giulia, among other models, and unverified rumors claim it's being designed with a topless variant in mind from the get-go. It might resurrect the Barracuda nameplate originally assigned to Plymouth when it makes its debut. Auto News Dodge Convertible Performance

Chrysler almost smothered the Hellcat before it lived

Chrysler's 6.2-liter supercharged Hellcat V8 was an absolute sensation from the very moment it was announced, and honestly, how could it not have been? Packing 707 horsepower and 650 pound-feet of torque, its numbers immediately put every other production muscle car (and many supercars) to shame. Plus, we soon learned that would be wrapped in a package retailing for around $60,000 - a pittance compared to other vehicles offering similar grunt. However, the Hellcat almost never got the chance to rumble under the hood of the Challenger and Charger.
The Hellcat was initially proposed back in 2011, back when Fiat was deciding its future strategy for Chrysler Group, according to Automotive News. At the time, the company was just emerging from its bankruptcy doldrums, and an ultra-high-performance V8 wasn't exactly a must-have item. The program didn't move forward. However, SRT engineers kept fighting, according to AN, and four months later, they received the green light to pull the project off the shelf and continue developing the Hellcat. The muscle car world is certainly better for that decision.
The work of those engineers focused on taking Chrysler's standard 6.2-liter V8 and making it reliably handle all of the extra power from the supercharger. "It came down to micron levels of changes in the crank to be able to withstand the pressures of the engine," said Chris Cowland, director of advanced and SRT powertrain, to Automotive News. The changes amounted to switching out about 91 percent of the parts to make the Hellcat, including some quite minuscule alterations. For example, the washer holding the supercharger pulley is embedded with industrial diamonds to keep it from slipping.

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.

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
