Hennessey turns a Cadillac CTS-V Coupe into a 1,200 hp monster

Hennessey VR1200 Twin Turbo Coupe front three-quarter viewMost Cadillacs are designed to woo potential buyers away from their BMWs with luxury and sophistication, but the Hennessey VR1200 Twin Turbo Coupe will frighten the competition into submission. Texas tuning legend John Hennessey gave this Caddy 1,200 horsepower.

The VR1200 Twin Turbo Coupe starts out as an already-impressive CTS-V, with a 556 hp, 6.2-liter V8. Hennessey increased displacement to 7.0 liters and, per the car’s name, added a pair of turbochargers.

To keep the engine from destroying itself, The VR1200 sports an air-to-water intercooler, heavy-duty fuel injectors, and reinforced engine internals. Forged aluminum pistons, forged steel connecting rods, and a complete balancing and blueprinting should cause gearheads to salivate.

The result is 1,226 hp and 1,109 lb-ft of torque. That means this Cadillac makes more power than any production car; the Bugatti Veyron Super Sport only makes 1,200 hp.

Putting all that power to the ground is a six-speed manual transmission. Mercedes-Benz AMG likes to say that its cars have too much torque for a clutch, but Hennessey seems to have found one (perhaps it’s made of Unobtanium) that can handle over 1,000 lb-ft. A specially built automatic is optional.

All that power means the VR1200 will probably have traction issues, so Hennessey fitted it with 20×13-inch rear wheels and 345/30-20 rear tires that could have been taken off Batman’s Tumbler.

With its bulging hood and hunkered-down stance (the car is lowered one inch), the VR1200 looks like a Batmobile, especially in black.

Hennessey Performance’s motto is simply “Making Fast Cars Since 1991,” and this Cadillac doesn’t let the side down. After all, with over 1,000 hp, one would expect a car to be fast. Hennessey says the VR1200 will do 0 to 60 mph in 2.9 seconds, within spitting distance of a Lamborghini Aventador. It will also cover the quarter mile in the coveted 10 second range; 10.2 seconds at 141 mph, to be exact.Hennessey VR1200 Twin Turbo Coupe rear three-quarter view

However, Hennessey’s biggest claim involves the VR1200’s top speed. The company says their crazy Caddy will hit 242 mph, making it faster than the McLaren F1 and nearly every other supercar.

In fact, there are only three production cars that can beat 242 mph: the Bugatti Veyron 16.4, SSC Ultimate Aero, and the aforementioned Veyron Super Sport. Being a modified CTS-V, the VR1200 isn’t really a production car, but if it really can hang with these machines, it would be the king of modified cars.

How much will the king of modified cars cost? With all the bells, whistles, and turbochargers, the VR1200 will cost roughly $295,000. That may seem like a lot for a Cadillac CTS, but if Hennessey’s performance claims are true, it will be a relative bargain compared to supercars like the Aventador, which starts at $406,000, and the $1,000,000 Veyron.

Those who want to taste the insanity of 1,200 hp should hurry: Hennessey is only making 12 VR1200 Twin Turbo Coupes.

Rivian R1T gets estimated 410 miles of range with Dual-Motor powertrain, Max Pack battery
People and a dog standing in front of a Rivian R1T electric pickup truck.

The Rivian R1T electric pickup truck now gets 410 miles of range with the new Max Pack battery and Dual-Motor powertrain, the company claims.

Rivian posted range estimates for the Max Pack, which is not available with Rivian's Quad-Motor powertrain, on X (formerly known as Twitter) on Wednesday, but those haven't been confirmed by the Environmental Protection Agency (EPA). The 410-mile range estimate applies to trucks with 21-inch wheels. Opting for 22-inch wheels knocks the estimated range down to 380 miles. The available 20-inch wheel and all-terrain tire combination — which helps maximize the R1T's impressive off-road capability — brings a further range reduction, to 355 miles.

Tesla Model 3 vs. Hyundai Ioniq 6: Which electric sedan is best?
Front three quarter view of the 2023 Hyundai Ioniq 6.

There are finally some more electric sedan options. For years, the Tesla Model 3 was really the only good electric sedan that comes at a reasonable price -- until, Hyundai recently launched the Ioniq 6. The Ioniq 6 certainly takes some cues from the larger Ioniq 5, but is smaller and sleeker, with a design seemingly inspired by the Porsche 911.

But the Tesla Model 3 is still clearly an excellent option for those looking for an electric car, and who don't want a larger crossover. Which is better? Here's a look.
The exterior design of the Tesla Model 3 and Hyundai Ioniq 6 is quite different. If you've seen a Tesla car before, then you'll immediately recognize the Model 3 -- it looks largely like a slightly different version of every other Tesla (except the Cybertruck).

Scout Motors Electric SUV: rumored price, release date, design, and more
Scout SUV Teaser

There's another electric SUV on the way, and this one comes with a familiar name. Volkswagen is reviving the classic Scout name for a new electric SUV that's billed as being an "RUV," or a rugged utility vehicle. And, it could well prove itself as the best electric SUV in its price range, when it does finally come out.

The new EV isn't due out for quite some time, but there's already a fair bit that we know about it. Curious to learn more? Here's everything you need to know about the upcoming Scout SUV.
There's very little we actually know about the Scout SUV so far, but we do know a little about the eventual design. A few teasers for the upcoming vehicle have been released, showing sketches of both the SUV and the accompanying pickup truck, along with what's presumably the front of the SUV -- though in a dark environment, with little detail.
