If you’re like me this Monday morning, you’re dragging a bit. Well, at least, I was dragging a bit. After absorbing the quick shot of auditory adrenaline that is the sinewy sounds of the Hennessey HPE700 Corvette Stingray, I am, like Radioactive Man, “up and atom!”

OK that was prodigiously dorky. My apologies. Let me make it up to you with the video itself.

And what is it that makes so much noise? It’s the Stingray’s LT1 6.2-liter V8 that’s had twin turbos bolted to it. Now, as you can see from the end of the video, it makes 608 horsepower and 564 pound-feet of torque.

Amazingly, those numbers are made with a measly seven-psi of boost and on 93 octane pump gasoline. To put that into perspective, the Mercedes CLA45 AMG’s turbo churns out 26.1 psi of boost. Going even lower, and closer to the psi rating of the HPE700’s turbos, your mom’s 1989 Volvo 740 turbo only made nine psi from its single, low-pressure turbo.

So to say the HPE700 is making quite a lot of power without much turbo help is like saying that Pharrell’s Dudley Do-Right hat at the Grammies was idiotic: it’s an understatement.

How did the mechanical wizards at Hennessey get so much power from the Stingray with some low-blowing turbos? They upgraded the fuel system, added a new intake and exhaust, and fiddled a bit with the ECU.

If you want more power from your Stingray than 608 ponies, luckily, Hennessey has you covered.

It also offers a prostate-shrinking 1,000 horsepower version. Giddy-up.

Mercedes-Benz EQG: range, price, release date, and more

Concept image of the larger electric G-Wagon

The G-Class is going electric. We already knew that Mercedes-Benz was working on an electric, small-size G-Wagon, but it looks like the company is also working on a larger G-Class SUV, in the form of the EQG. In fact, Mercedes has gone as far as to show off a concept version of the off-roader.

While there's much we don't know about what will become the production model of the EQG, Mercedes has also shared a lot about it. Curious about whether the Mercedes-Benz EQG could be the EV for you? Here's everything we know so far.
Design
Fear not -- the EQG will retain many of the design aspects of the G-Class that you already know and love but with a modern face-lift. The EQG will keep the boxy design that gives the G-Class a classic look but with some additional modern styling, at least if the concept version is anything to go by.

Rivian R2 vs. Kia EV9: battle of affordable electric SUVs

Kia EV9 GT-Line Three Quarters

The long-awaited Rivian R2 has finally been announced, and it's an excellent option for those who want an electric SUV that doesn't completely break the bank. Sure, the R2 isn't cheap -- but it's a whole lot cheaper than most other EVs out there, especially when it comes to SUVs. But Rivian isn't the only company trying to tackle the problem of the budget electric SUV. The Kia EV9 is finally available, and it too offers a modern design and a range of helpful features.

Given the fact that the Rivian R2 and Kia EV9 are two electric SUVs in a similar price range, you might be wondering which is better for your needs. That's why we put the Rivian R2 and the Kia EV9 head-to-head.
Design
Both the Rivian R2 and the Kia EV9 are actual SUVs -- not crossovers pretending to be SUVs, like plenty of other EVs out there. The two vehicles offer big, boxy designs and plenty of interior space, making them excellent options for families or those who need that extra storage.
