Enliven your Monday morning with the sounds of Hennessey’s twin-turbo Corvette Stingray

Add as a preferred source on Google

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.

If there was ever an electric truck that looked like it needed a splash of color, it was Slate's. The Bezos-backed startup has announced a new partnership with Crayola, bringing the iconic crayon maker's unmistakable palette to its minimalist electric pickup. And yes, one of the available colors is actually called Razzmatazz.

Self-driving cars keep getting in the way of first responders, and Uncle Sam just ran out of patience
Robotaxis are supposed to make roads safer, but first responders say they're becoming a real problem.
Waymo Jaguar I-PACE sensors close up

Self-driving cars are supposed to make our roads safer, but it seems that they are  doing the opposite. NHTSA administrator Jonathan Morrison sent a letter to autonomous vehicle developers this week, and he didn't hold back. He called the pattern of driverless cars getting in the way of first responders "unacceptable," and said a car that can't safely handle an emergency scene is a danger to everyone around it.

What's actually going wrong?

Xiaomi built an SUV that doubles as a camping tent, and its range numbers are equally wild
A pop-up camping roof, 300 miles of electric range, and a gas extender for when the tent life takes you somewhere the grid hasn't reached yet.
Car, Transportation, Vehicle

Xiaomi went from selling smartphones to making profitable electric cars and turned profitable in just two years, a feat that took Tesla a decade. 

Now, the automaker has unveiled a whole new EV sub-brand called Sky Nomad; it’s answer to the outdoor and family lifestyle market. What’s even more interesting is the lineup’s first vehicle could come with a built-in retractable roof that literally pops up into a camping tent.
