Demon-slaying Hennessey Exorcist Camaro hits top speed of 217 mph

THE EXORCIST 217 MPH Top Speed Test

When Dodge launched its 840-horsepower Challenger Demon last year, tuner Hennessey Performance Engineering decided to one-up it by turning the Chevrolet Camaro ZL1 into the 1,000-hp Exorcist (get it?). Now we’re finding out just how potent a Camaro with a four-digit horsepower figure can be.

Hennessey recently ran the Exorcist up to a top speed of 217 mph at the Continental Tire Proving Grounds in Uvalde, Texas. Dodge doesn’t quote a top speed for the Challenger Demon, but Hennessey noted that its Camaro beat the 213-mph claimed top speed of the 2019 Chevrolet Corvette ZR1. The Exorcist is also faster than a host of pedigreed supercars, including the Ferrari 488 Pista and McLaren 720S.

The Exorcist starts life as a Camaro ZL1, sporting a 6.2-liter supercharged V8 that produces 650 hp from the factory. Hennessey replaces the factory-installed supercharger with a larger unit, and modifies the intercooler system, cylinder heads, and other components. The car is also treated to a new stainless-steel exhaust system. The modifications come with their own three-year/36,000-mile warranty.

Hennessey used a 10-speed automatic transmission in its test car (the stock ZL1 is also available with a six-speed manual), and said the Exorcist hit its top speed in ninth gear. The company hasn’t tested the Exorcist on the Challenger Demon’s home turf — the drag strip — yet, but said it’s planning to conduct 0-to-60 mph and quarter-mile acceleration tests soon. Dodge claims the Demon will do 0 to 60 mph in 2.3 seconds, and run the quarter mile in 9.65 seconds at 140 mph.

Hennessey has already deliver 20 Exorcists to customers, and plans to build a total of 100 cars. The total cost of an Exorcist equipped identically to the top-speed test car is $119,950. That’s a lot of money for a Camaro, even one with supercar-rivaling speed. It’s also about $35,000 more than a Demon, and about the same as a 2019 Corvette ZR1. The Exorcist is a bit faster and roomier than the ‘Vette, but it’s unclear whether it can match the ZR1 in the corners. We’ll find out soon, as Hennessey is planning to take the Exorcist to a proper road course in addition to the drag strip.

Kia EV3 vs Tesla Model Y: Can Kia’s new entry-level car take on Tesla?
White Kia EV3

The Kia EV3 is finally coming, and it could well end up being the best small-size electric SUV to buy when it finally rolls out. It's smaller than the Kia EV9, but it offers many of the same design elements and features. But there's another small-size electric car that's currently one of the most popular vehicles out there -- the Tesla Model Y.

How does the Kia EV3 compare with the Tesla Model Y? And is one vehicle actually better than the other? We put the Kia EV3 and the Tesla Model Y head-to-head to find out.
Design
The design of the Kia EV3 is very different than that of the Model Y, though they're both reasonably good-looking vehicles.

Entry-level Cadillac Optiq EV promises 300 miles of range for $54,000
2025 Cadillac Optiq front three quarter view.

The 2025 Cadillac Optiq will be the General Motors luxury brand's entry-level EV when it starts production late this fall. But it won't have entry-level specs.

After unveiling the Optiq in November 2023, Cadillac is now filling in some of the blanks on this electric crossover SUV's spec sheet. We now know that the Optiq will feature a standard dual-motor all-wheel drive powertrain tuned for 300 horsepower and 354 pound-feet of torque, along with an 85-kilowatt-hour battery pack providing an estimated range of over 300 miles. Like other GM EVs, the Optiq will be capable of one-pedal driving, with regenerative braking adjustable via a steering wheel paddle.

2024 Ford Mustang Mach-E Rally first drive: old pony learns new trick
2024 Ford Mustang Mach-E Rally driving on dirt.

With its Mustang Mach-E, Ford promised an electric SUV imbued with the spirit of the iconic Mustang performance car. Now well into its production run, the Mach-E is living up to its Mustang billing in that, like the traditional internal-combustion Mustang coupe and convertible, Ford wants to grow the herd of Mach-E variants.

Introduced for the 2021 model year, the Mach-E is nearing the point where most vehicles would see a redesign, or at least a major update. That seems especially pressing given the accumulation of fresher competition in the form of the Hyundai Ioniq 5, Kia EV6, and Chevrolet Blazer EV. But instead of a redesign, the big news for the 2024 Mustang Mach-E is a new Rally model designed for dirt-road driving.
