Inner Demon revealed: 840 hp and other jaw-dropping details

After months of teasers, rumors, cryptic messages, and veiled hints, the 2018 Dodge Challenger SRT Demon is finally here, and it's as wonderfully insane as we hoped it would be. Finally we know the facts and figures that Dodge has been hinting at for so long. 840 horsepower. 770 lb-ft of torque. 2.3 seconds to 60 mph. A quarter-mile run of 9.65 @ 140 mph. While pricing hasn't been announced, Dodge is trying to keep it under $100,000. That horsepower figure makes this the most powerful production V8 ever. With those 0-60 and quarter-mile times, it's also NHRA certified as the quickest production car ever. Someone with the means needs to line a Demon up against a Tesla Model S P100D. All that power and all of the Demon's trick launching software and hardware will throw a driver back against their seat with 1.8 Gs. Drivers will be seeing a bit of sky, as the Demon is the first production car to pull a wheelie from a dead stop. Yes, this is all totally and 100 percent street legal. View 48 Photos In order to make all this power, the red-painted supercharged 6.2-liter Hemi V8 has been significantly improved over the Hellcat. It's equipped with a larger 2.7-liter supercharger that turns the boost up to 14.5 psi, redlines at 6,500, and has what Dodge is calling SRT Power Chiller, a system that uses the air conditioning to cool the air coming in through the new Air Grabber hood scoop. In order to keep your engine running time and time again, there is an after-run cooler than cools the supercharger after the car is shut off. The pistons and connecting rods have been strengthened to deal with the higher load. In order to feed enough juice into the engine, the Demon uses dual fuel pumps. We assume that a decent EPA rating wasn't on the top of the engineer's list. Oh, and the Demon can run on 100-octane with the press of a button. With the traditional SRT black and red keys, the Demon actually has three horsepower ratings: 500 with the black key, 808 with the red key, and the full 840 with the red key and 100-octane fuel. Don't worry, even if you have the black key, the Demon will drop the 1/4 mile in 11.59 seconds, still quicker than almost anything around. Most of the rest you already know from the seemingly endless teasers. The Demon wears lightweight wheels with sticky 315/40R18 Nitto drag radials at all four corners.

Hypermiling a Ram 1500 EcoDiesel to 38.1 mpg

You never quite know what Wayne Gerdes has up his sleeve. The man who coined the term hypermiling is always looking for adventurous ways to prove that anyone – even you... yes, you – can eke out more miles per gallon just by changing the way you drive. Saying that is easy. Proving it by going on outlandish cross-country drives is hard. But for Gerdes and his team of fuel economy fiends over at CleanMPG, hard is half the fun. Our latest adventure appeared, at first glance, to be nearly impossible. Which is why we always answer the phone when Gerdes calls. He likes to take journalists along on his drives, not only to try teach us how to hypermile but also to prove that we can be taught. The first time I 'helped' him and his team was when we got over 30 miles per gallon in a 2011 Ford F-150 XLT with the EcoBoost 3.5-liter V6. The EPA rated that truck with at just 16 mpg in the city and 22 on the highway. So, we'll count that trip as a success. Next up was a cross-country drive last fall in a trio of Audi TDI vehicles to prove that you don't need to drive extra slow to beat the EPA numbers. In fact, we made it from Los Angeles to New York City in just over 46 hours, cramped but not cranky. We had once again proven that how you drive is hugely important to your fuel usage. Our latest adventure appeared, at first glance, to be nearly impossible. The EPA says that the Ram 1500 EcoDiesel we would be driving gets just 22 combined mpg (19 city and 27 highway). Gerdes' idea was to drive it as far north from Houston, TX towards Detroit, MI as we could go on one tank. The day before we left, our itinerary got an extra stop. Instead of taking one of the official Shell Eco-marathon prototype vehicles to Detroit, it was decided to bring the winning diesel-powered prototype from the just-finished event to The Henry Ford Museum, where it had been arranged the car would be displayed. The winning car was built by a small team (just four students) from Sullivan High School in Sullivan, IN, who managed to beat a number of college teams with a score of 1,899.32 mpg. That target would be a bit out of reach for the Ram, but could we get 1,000 miles from the tank? Since the truck has a 26 gallon tank (officially, anyway), that would mean the EPA says we could only go 702 miles, assuming all highway driving. Could we make up 300 miles with careful driving? That spells both challenge and fun.

Dodge Hellcat Widebody delivers Christmas tree at 174 mph

The holidays are here, and so last-minute shoppers are going to be in a serious rush to get all the items they need, especially Christmas shoppers that haven't even put up a tree yet. Those seriously late folks may want to invest in a Challenger Hellcat because apparently they can go an incredible 174 mph with a Christmas tree strapped to the roof. This was discovered by the folks at Hennessey. They got a Hellcat Widebody from Dodge for the little experiment, along with a suction cup mount roof rack from SeaSucker and a real Christmas tree from Lowe's. Then it was off to the Continental Tire test track in Texas to see how fast it could go, which, as mentioned was 174 mph. As you'll see in the video, it takes quite a bit of road to move up from 170 to 174 mph. It's impressive that the tree and roof rack don't seem to budge. And it's all capped off with a huge smokey burnout to the sound of V8 rumble and supercharger whine. It's a fun way to get into the holiday spirit. And we'll look forward to next year when maybe Dodge will give Hennessey a Demon to try out. Related Video:
