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.

The week in EV tech: From sky-high dreams to ground-level drama
tesla robotaxi feud alef in transition flight

Welcome to Digital Trends’ weekly recap of the revolutionary technology powering, connecting, and now driving next-gen electric vehicles. 
Buckle up, folks — this week we’re taking off with a look at the futuristic dream of flying electric cars possibly gliding above U.S. roads sooner than you think. But before we get carried away, let’s bring it back down to the bumpy road of present-day realities.
Even if you’re mostly interested about the tech powering the electric vehicle (EV) revolution, it’s become increasingly hard to avoid the politics around it: You guessed it, we’re talking about this week’s public feud between Tesla CEO Elon Musk and U.S. President Donald Trump.
What does this have to do with EV tech? Well, quite a lot actually. For starters, the technology behind Tesla’s Autopilot and Full-Self Driving (FSD) modes may return in the crosshairs of regulators: Despite the names, these are still driver-assist features that require active driver supervision, and until Trump’s election, they had been under heavy scrutiny by safety regulators for several years.
Last year, the National Highway Traffic Safety Administration  (NHTSA) launched an investigation into 2.4 million Tesla vehicles equipped with FSD. Big questions remain about the driver-assist system's performance under adverse, yet naturally-occurring conditions such as fog, sun glare, rain, and snow.
When Musk, who spent about $275 million to help elect Trump, was appointed to head a newly-created Department of Government Efficiency (DOGE), it raised more than a few eyebrows about his power and influence over the regulators who are supposed to oversee traffic safety, and therefore Tesla.
It didn’t help that the Trump administration followed Musk’s recommendations and relaxed crash-reporting requirements put in place since 2021, while also relaxing rules to accelerate the deployment of fully-automated robotaxis.
The Trump/Musk clash takes place just as Tesla is due to launch its robotaxi pilot progam in Texas later this month. While Trump is now threatening to pull billions of dollars in government subsidies and contracts from Musk’s companies, it’s unclear whether he might pressure the Department of Transportation to again tighten the regulatory screws on Tesla. What is clear is that Trump has never been a fan of electric vehicles and is already trying to end federal subsidies on EV purchases and leases. And while he had made a big deal about buying a bright red Tesla Model S back in March, Trump now says he wants to sell it.
Back to the tech
Meanwhile, Tesla is still required to respond to information and data requests from NHTSA regarding the safety of its robotaxis by July 1. And ultimately, it should come down to the performance of the technology.
For Autopilot and FSD, Tesla has opted for less expensive navigational tech relying on multiple onboard cameras that feed AI machine-learning models. But especially for so-called adverse driving conditions, it’s the more expensive technology relying on a blend of pre-mapped roads, sensors, cameras, radar, and lidar (a laser-light radar) which has received the nod of regulators.
Waymo, the sole robotaxi service currently operating in the U.S., and Zoox, Amazon’s upcoming robotaxi service, both use that blend of navigational tech.
For its robotaxis, Tesla is said to have upped its game in terms of autonomous driving with its Hardware 4 (HW4) technology, which does include radar sensors and promises enhanced environmental perception.
Will that be enough for Tesla to convince regulators, catch up with Waymo, or compete effectively with Zoox?
We’ll have to wait and see.
Flying cars
In a recent edition, we noted that while consumer confidence about robotaxi technology is on the rise, most people also want more data before they hop into a self-driving vehicle.
What about flying taxis? According to a recent survey by Honeywell, nearly all U.S. airline fliers, or 98%, said they would consider using a so-called electric vertical take-off and landing vehicle, or eVTOL, as part of their travel journey.
But while the buzz around flying electric vehicles has mostly focused on air taxis— like Archer Aviation’s Midnight, expected to fly athletes around the 2028 LA Olympics, or Joby’s slick air taxi, backed by Toyota — one California startup is shooting for something a little more... driveable.
Meet Alef Aeronautics, a Bay Area company that wants to put the “car” back in “flying car.” This week, Alef announced it has received over 3,400 pre-orders for its electric flying vehicle, the Model A — and get this: it’s not a futuristic prototype gathering dust in a lab. Alef says production could begin by the end of 2025, or early next year.
On the ground, the Model A operates like a low-speed electric car, complete with hub motors in the wheels and—wait for it—a real steering wheel. You can legally drive it at up to 25 mph on public roads, parking it in a normal garage like any other EV. It’s refreshingly manual in an increasingly hands-free world.
But when it's time for lift off, the steering wheel takes a backseat. For vertical takeoff and flight, the Model A transforms into a drone-like aircraft. Its cabin rotates sideways to create lift, and eight electric rotors—controlled by a flight system and joysticks—take over. No pedals, no yoke, just a bit of joystick magic (or autopilot, if you prefer).
The Model A has already received the nod from regulators for test flights.
While the $300,000 price tag won’t fit everyone’s budget, the company is clearly betting on a future where you don’t have to choose between a car and a flying machine—you can have both.
