Here are the Challenger SRT Demon's bare-minimum performance numbers

This week's Dodge Challenger SRT Demon teaser video provides what seems like more concrete evidence than any of the others before it. We say it seems that way because the numbers flashed on the screen are likely not showing us everything the car has to offer. So we're looking at these as the minimum performance stats and expecting Dodge to reveal even crazier numbers alongside the car next month. The video also provides some hints at features and modes the car will offer. Let's pick it apart. First off, there's the performance data from the various SRT Performance Pages screens. The 0–60 mph time is 3.0 seconds, which compares well to the "regular" Hellcat's 3.5-second manufacturer claim. Then there are two 0–100 times: 6.08 and 6.8. An eighth-mile time of 6.6 seconds at 125 mph and a quarter-mile time of 0.5 seconds at 129 mph lead us to believe the driver lifted off the throttle in that second eighth-mile and that the car will actually do the quarter in the low 10s. For reference, Dodge claims an 11.2-second quarter for the Hellcat on its street tires and a 10.8 with race slicks.

A graph shows it heading up toward 10 psi but the final spike is obscured by a Demon head. Cute. There's a hint at horsepower and torque numbers in a graph on the Dyno page, which shows both peaking around 750. In every shot of this video, the clock is set to 7:57, which we think means it either has that much power or, well, more. We think there's more to it because it appears that part of the graph above the dyno run shown, which would reach to 800 or 850, has been blanked out. A horsepower total of 808 would be a nice complement to the Hellcat's 707, don't you think? We can see from the shift indicator screen that the car will come with or at least offer the eight-speed automatic that's also available in the Hellcat and other Challengers. That's likely to be the best option for drag racing. The Demon's user-defined shift light feature, which lets you choose an optimal shift rpm for each individual gear, also suggests that a six-speed manual will be available. We'll cover the many modes and settings highlighted in this video in a separate post. There's a lot to discuss. Related Video: This content is hosted by a third party.

All hail the Hellephant, Mopar's 1,000-horsepower crate engine

It's shocking to say this, but the all-powerful Dodge Demon looks weak now that Mopar has unleashed the Hellephant. This crate motor makes 1,000 horsepower and 950 pound-feet of torque, and its name is a combination of the nickname for the old 426-cubic-inch Hemi V8 and, obviously, the Hellcat. This monster is a 426-cubic-inch version of the current third-generation Hemi V8 topped by a supercharger similar to what the Hellcat line packs. Everything is cranked up to — or perhaps, past — 11. The engine block is made of aluminum and weighs 100 pounds less than the equivalent iron block. All of the internals are forged. The stroke and bore have been increased. The supercharger produces 15 pounds of boost and displaces 3 liters; more than the 2.7-liter blower on the Demon and the 2.4-liter blower on the Hellcat. And as big and powerful as it is, it will still rev to 7,000 rpm. It's a thoroughly monstrous motor, but shockingly, it won't be that difficult to live with. For one thing, Mopar will offer a complete kit to get the engine up and running, including an engine computer, wiring harness and drive-by-wire throttle. It also runs on 93-octane pump gas. That's especially amazing considering the Demon engine "only" makes 840 horsepower, and that's on race gas with 100+ octane fuel. It also has us wondering what the Hellephant could make on racing fuel. The Mopar folks did say that there's room to add more power. Pricing wasn't announced for the Hellephant engine. The Hellcat crate engine retails at $19,350 directly from Mopar, so it's safe to assume that the Hellephant will go for more. The installation kit with the computer and harness will be an extra charge of likely over $2,000, based on the Hellcat kit. The engine and the kit will be available in the first quarter of 2019.

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.
