Watch these Dodge Demons explode on a Texas drag strip

The Dodge Challenger SRT Demon is extremely quick. It can hit 60 mph from a dead stop in less time than it takes to read this sentence thanks to its supercharged 6.2-liter V8. That engine makes up to 840 horsepower and 770 pound-feet of torque, depending on what octane is running through the fuel lines. That's a ton of power going solely to the rear wheels. So much so that Dodge developed a number of features and a new set of tires specifically for the car. In our time with the Demon, the car took abuse run after run on a drag strip without skipping a beat, but it seems some actual owners aren't quite so lucky. Just take a look at what happened to a few of these cars. You can see the whole car shake and jitter right as the whole rear explodes in front of the tree. It seems the initial shock from the launch — the most taxing bit of any drag run — is what kills the differentials. Catastrophic failure is rarely pretty, but it is neat to see the whole thing occur in slow motion. Three more cars — four stock and one modified in total — suffered similar fates. Not a great look for Dodge or SRT. According to The Drive, a private drag event in Texas drew a number of Demon owners all trying to beat NHRA NHRA Top Fuel racer Leah Pritchett's time in her personal Dodge Demon — 42 stock Demons attended along with five modified cars. While no one managed to match her 9.65-second quarter-mile run, a few owners did dip below 10 seconds. Now, there are a few of caveats we must address. First, with any modified car, you run the risk of breaking something, even with a car that's set up from stock specifically for drag strips. Even a set of tires like the Mickey Thompsons shown in the video above can have an effect on driveline components. Horsepower may be king, but it's torque that's the rear killer. All that torque sends a shock through the car. Adding even more with aftermarket parts increases the risk of something failing. The modified car was apparently pushing out about 1,000 horsepower. That said, four of the five vehicles were stock, so any extra power or torque should theoretically be a non-factor. The drag strip's surface was maintained by a company called Mass Traction. FCA used Mass Traction during the Demon's development, so that too should be a non-factor in the part's failure. It's unclear what exactly caused the failures, though The Drive reports that FCA officials are investigating the matter. Related Video: This content is hosted by a third party.

Hennessey Dodge Demon sets hellishly fast quarter-mile time

The Dodge Demon doesn't strike us as a muscle car much in need of a performance makeover. After all, this 840-horsepower MoPar machine's voracious quest for straight-line speed means it trims weight by jettisoning everything from a front passenger seat and rear seat, to its stereo and all carpeting in the trunk. The folks at Hennessey apparently think that's not nearly extreme enough. So, the Texas-based tuning outfit has turned the Demon into a 1,035-horsepower mega beast that runs a quarter-mile in 9.14 seconds at 152 mph. That's fast, really fast. In fact, the HPE1000 is now the world's fastest Dodge Demon, having set its record-setting pace at Lonestar Motorsports Park on May 8. "The 2018 Demon is a street-legal rocket from Dodge, but we wanted to take the car's impressive track times to an industry leading level." said president and company founder, John Hennessey. For comparison, the stock Dodge Demon is credited with running the quarter-mile in 9.65 seconds at 140 mph. The main HPE1000 modification involves replacing the stock 2.7-liter supercharger with one that's a staggering 4.5-liters in capacity. Also included in the Hennessey toy-chest are stainless steel long tube headers, a high-flow air induction system, upgraded throttle body, upgraded fuel pump and fuel injectors, along with custom engine management calibration. When all is said and done, the HPE1000 Dodge Demon delivers a total of 1,035 horsepower at 6,500 rpm and 948 pound-feet of torque at 4,200 rpm. While the standard Demon accelerates from 0-60 mph in only 2.3 seconds, the Hennessey variant trims this down to only 1.9 seconds. That's quick enough to make a Bugatti Chiron blush. Hennessey hasn't stated what all this will cost, though the company did say production of these devilishly fast Demons will be limited to only 50 examples. Customers also receive a 1-year/12,000-mile warranty, which seems a nice touch for a car that's downright scary with its performance specs.

Cold start comparison: 2020 Alfa Romeo Giulia Quadrifoglio vs. 2013 Dodge Challenger SRT8

The 2020 Alfa Romeo Giulia Quadrifoglio is a five-seat, compact luxury sport sedan packing 505 horsepower thanks to a 2.9-liter twin-turbocharged V6. My personal 2013 Dodge Challenger SRT8 392 is ... well ... not. It's a full-sized muscle coupe whose iron-block 6.4-liter V8 makes 470 hp in the very traditional way: it's freakin' huge, like everything else about the car.  On paper, these two have nothing in common beyond the fact that they were built by the same multi-national manufacturing entity.  But if paper were the be-all and end-all of automotive rankings, everybody would buy the same car. And we don't, especially as enthusiasts. Whether it's looks or tuning or vague "intangibles" or something as simple as the way a car sounds, we often put a priority on the things that trigger our emotions rather than setting out to simply buy whatever the "best" car is at that particular moment.  So, what do these two have in common? They both sound really, really good. Like looks, sounds are subjective. While a rubric most assuredly exists in the world of marketing (attraction is as much a science as any other human response), we have no way of objectively scoring the beauty of either of these cars, and the same applies to the qualities of the sound waves being emitted through their tail pipes.  But we can measure how loud they are. In fact, there's even an app for that. Dozens, as it turns out. So, I picked one at random that recorded peak loudness levels, and set off to conduct an entirely pointless and only vaguely scientific experiment with the two cars that happened to be in my garage at the same time.  For the test, I opened up a window and cracked the garage door (so as not to inflict carbon monoxide poisoning upon myself in the name of discovery), and then placed my phone on a tripod behind the center of each car's trunk lid. I fired each one up and let the app do the rest. I then placed my GoPro on top of the trunk for each test so that I could review the video afterward for any anomalies.  I started with the Challenger. The 6.4-liter Hemi under the hood of this big coupe is essentially the same lump found under the hood of quite a few Ram pickups, and it has the accessories to prove it. Its starter is loud and distinctive. Almost as loud, it turns out, as the exhaust itself. As its loud pew-pew faded behind the V8's barking cold start, we recorded a peak of 83.7 decibels. In the app's judgment, that's roughly the equivalent of a busy street.
