Watch Hennessey takes this tuned Chevrolet SS to 163 mph on a Texas toll road

The Chevy SS really is a ’60s muscle car that traveled forward in time … and also from Australia. How do we know this? Well, it’s a car that you can still legitimately get souped-up. Fortunately for everyone who loves a good muscle car, Hennessey has done just that.

In this video we see Hennessey take a supercharged SS out on a Texas toll road for a little bit of testing. Refreshingly enough, Hennessey isn’t doing the testing for his ego; this 163 mph speed run is for the good of the community. Well, at least the toll road community. That’s because Hennessey apparently regularly works with the toll road, and the state police, to make sure that radar traps and toll collection systems work for everyone … especially those more than doubling the posted speed.

On an unrelated note, kudos to the Texas state police for running some truly badass looking Dodge Chargers as highway pursuit cars.

While the modifications are still in their initial stages, the results look impressive. By my count, 0-163 mph took just over 17 seconds. That is, to put it mildly, brisk. And if it weren’t for the SS’ gearing, it could be doing a lot more than just 163 mph.

Hennessey is still cagey about some of the details, but this bad boy is putting out upwards of 600 horsepower. Quite the jump over the standard 415 hp but not as insane as some of the other tuning projects that Hennessey has gotten up to over the years, like the 738 hp Ferrari 458 Italia.

If this level of madness isn’t quite your speed, Hennessey should be offering some more sensible performance modifications like air induction systems, intercoolers, turbos, and suspension upgrades.

All of this tuning madness really is enough to make you think that you are in the ’60s when peak performance was just a new carburetor away.

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 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.

Volkswagen reinvented one of its most iconic models with the ID.Buzz, a modern, all-electric homage to the classic Microbus. But that's not the only fan favorite vehicle currently in the automaker's catalog.

Debuting at the 2023 Munich Auto Show, the Volkswagen ID.GTI concept aims to do for the Golf GTI hot hatchback — VW's signature performance car — what the ID.Buzz did for the Microbus. VW claims a production version has already been given the green light, although it won't say when it will appear.
