2015 Dodge Challenger SRT Hellcat revving is sonic bacon

This is the Dodge Challenger SRT Hellcat, and we're sure that by now, you know its stats, including over 600 horsepower from its 6.2-liter, supercharged V8. What, pray tell, does that blown engine sound like, though?
At least judging on the sonic strength of this video, it's very, very dirty. Honestly, it sounds unlike anything that's come out of the Chrysler Group in a long time, if ever. It's loud, almost brutally so, with a bark that few road-going V8s can match.
Of course, you should be the final judge here. Take a look and a listen at the two videos below, one of which comes from our friends at Cars.com that provides a nice look under the hood, and then let us know what you think of the Hellcat's singing voice in Comments.

Dodge could enter Peugeot's Le Mans-bound 9x8 hypercar in IMSA races

Fiat-Chrysler Automobiles (FCA) and PSA Group merged under the Stellantis umbrella in early 2021 to achieve economies of scale, and this benefit could surprisingly extend to racing. Executives are debating whether to give Dodge its own version of Peugeot's recently-unveiled 9x8 hypercar to race in America, according to a recent report. "While we only heard [the new rules] confirmed a week ago, it has certainly led to some very open discussion, not only about whether Peugeot might add races in the United States, but also about whether the spine of this car might have opportunities with other brands in the Stellantis Group. There are no conclusions yet, but there are now open discussions," affirmed Jean-Marc Finot, the Senior Vice President of Stellantis, in an interview with Racer. His comments refer to an agreement signed in July 2021 by the Automobile Club de l'Ouest (ACO), the Federation Internationale de l'Automobile (FIA), and the International Motor Sports Association (IMSA). They chose to align their technical regulations to let manufacturers compete in different events on both sides of the pond without going through the resource-consuming process of developing a specific car for each series. As of writing, the Le Mans Hypercar (LMH) and Le Mans Daytona h (LMDh) categories fall under the newly-announced common set of rules. On the surface, this means Peugeot could enter its 9X8 (pictured) in the WeatherTech SportsCar Championship as soon as the 2023 season. While this is seemingly under consideration, Peugeot has little to gain from winning a major race in the United States. It hasn't sold cars here since 1991, and its long-mooted comeback was canned after PSA merged with FCA. Giving a variant of the 9X8 to Dodge is a more credible possibility, according to Racer. If not Dodge, then who else? Chrysler hasn't been linked to racing or performance for decades. Jeep is no stranger to performance vehicles, but IMSA would be pushing it. Ram is Ram, while Fiat, Alfa Romeo, and Maserati are rooted in Europe. The rest of the Stellantis brands (like Opel, Lancia, and Citroen) are not distributed in America. Nothing is official, and the publication stressed it's unclear whether Dodge will commit part- or full-time to the series (assuming the program receives the green light). Finot underlined the parallel car would use the 9X8's "spine," so don't expect to see a Peugeot hypercar with a Dodge emblem driving flat-out on the Sebring International Raceway.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"
