Only the rev limiter can stop Hennessey’s 195-mph HPE700 Mustang

Few drivers will ever explore the true limits of their cars, and that’s probably a good thing. John Hennessey specializes in doing just that.

We previewed the famed tuner’s HPE700 Mustang last year, which bolts a 2.9-liter supercharger system (among other things) to the 2015 Ford Mustang GT. With the Hennessey badge, Ford’s 5.0-liter ‘Coyote’ V8 makes 717 horsepower and 632 pound-feet of torque at the crank, which allows for a 0 to 60 mph time of 3.6 seconds and quarter-mile figure of 11.2 seconds.

A new video of the car has been posted by Mr. Hennessey himself, and it shows his personal HPE700 performing a top speed run at the Continental Tires Proving Grounds in Uvalde, Texas.

On the 8.5-mile course, Hennessey was able to hit a GPS-verified 195.2 mph before the rev limiter kicked in. The car sounds like a screaming jet fighter as it flies around the test track, and you can skip to 3:10 in the video for proof. The run starts at 2:20.

“Cruising through the final turn I was trying to maintain 120-130 mph while building some speed as I neared the straight,” Hennessey recounted. “When I hit the straight, I wanted to be around 140 mph and then let all of the Mustang’s horsepower run wide open. The car pulled very strong and just kept pulling. I hit a pretty nasty bump around 170 mph and kept my foot on the gas. Then I hit the rev limiter at just over 195 mph according to the Racelogic VBox display.”

In October, Hennessey stated only 500 examples of the HPE700 Mustang would be built for the 2015 model year. The package starts at $59,500, which includes the $32,300 base MSRP of a Mustang GT. Options like carbon-fiber bodywork, 20-inch Hennessey wheels, and a Brembo brake package are also available.

Are EVs safe? From battery fires to autopilot, here are the facts
Lucid Air electric car

While many people will be primarily concerned with EV range before buying their first electric vehicle, others are a little nervous about having a giant lithium-ion battery strapped to their car's undercarriage. Those things can catch fire -- just ask Chevy Bolt owners. But how much of a real danger is that? And should it prevent you from buying an EV?
What safety features do EV batteries have?
The major safety issue with lithium-ion batteries is their temperature. If they get too hot, they're prone to igniting. If they get too cold, they freeze and permanently stop working. Charge and discharge rates need to be carefully regulated too, or you'll get electrical fires. Over time, small imperfections in a battery's structure can lead to short circuits and reduced lifetime.

EVs have what are called battery management systems (BMS) to keep tabs on all of these variables. The BMS will generate warnings when needed and intervene directly by cutting off power if things get out of hand. EV battery packs also have thermal management systems. Typically, this is a closed loop of liquid coolant flowing alongside the battery cells, but air cooling and welding battery cells directly to the car chassis are also means of mitigating extreme heat.
How well do EVs handle a crash?
Since there's no engine at the front of an EV, the hood typically houses a frunk -- meaning a front trunk. This acts as a large crumple zone in the case of a head-on accident. One crash in Germany avoided casualties thanks to this inherent characteristic of electric vehicles. Crash tests bear this out. Popular EVs like the Tesla Model 3, Hyundai Ioniq 5, and Nissan Leaf have all received overall five-star ratings from the National Highway Traffic Safety Administration (NHTSA).

The locations of over 2 million Toyota cars were exposed for 10 years

Ever get the sense that you're being tracked? Well, if you're a Toyota driver, you may have been. Toyota has disclosed in a statement that the locations of 2,150,000 of its customers were at risk of breach between November 6, 20i3, and April 17, 2023.

Information that was at risk specifically included the vehicle GPS and navigation terminal ID number, the chassis number, and the location of the vehicle with time data. This information is related to Toyota's cloud-based Connected service, which is used to remind owners to get maintenance done, stream entertainment in the car, and help find owners during emergency situations. Users who used services like Toyota Connected, G-Link, and G-Book were potentially affected.

An autonomous Stagecoach bus.

A fleet of full-size autonomous buses is now serving passengers along a 15-mile route in Scotland in what is the first service of its kind in the U.K.

Five of the buses are running between Edinburgh to a destination that takes it across Scotland’s famous Forth Road Bridge.
