2018 Dodge Challenger SRT Demon is 200+ Pounds Lighter Than Hellcat

  2018 Dodge Challenger SRT Demon is 200+ Pounds Lighter Than Hellcat The tease for the 2018 Dodge Challenger SRT Demon continues with a new video posted to www.ifyouknowyouknow.com. The video, titled “Reduction,” reveals that the Demon trims more than 200 pounds from the curb weight of its Hellcat sibling. Dodge says the Challenger Demon will be the brand’s performance halo car, and though it hasn’t revealedDodge says the Challenger Demon will be the brand's performance halo car, and though it hasn't revealed numbers yet, we expect the new model's output to eclipse the Challenger Hellcat's 707 hp and 650 lb-ft of torque.

That’s how few seconds Dodge claims the Demon needs to run a quarter -mile, blistering the trap at 140 mph. If we can match that figure—a sizable “if,” since our testing Dodge Announces Challenger SRT Demon Feature 2018 Jeep Grand Cherokee Trackhawk Dissected: Powertrain, Performance

That answers your first question about the 2018 Dodge Challenger SRT Demon . Now for the window dressing. The Demon can hit 60 miles per hour in 2.3 seconds pulling 1.8 G’s, with a 9.65 quarter -mile drag time at 140 mph, and the 6.2-liter Hemi Demon V8 engine can pump out 770 lb-ft

2018 Dodge Challenger SRT Demon sheds seats and insulation to drop weight

  2018 Dodge Challenger SRT Demon sheds seats and insulation to drop weight Losing weight doesn't bedevil Dodge.The Demon loses 113 pounds by making the front passenger seat with its seatbelt (58 pounds) and back seat (55 pounds including restraints and floor mats) optional, which accounts for a large chunk of the weight loss compare to the Hellcat.

So equipped, the Demon will demolish the quarter -mile in 9.65 seconds at 140 mph, Dodge claims. The Demon goes on sale in fall 2017; only 3000 will be produced. Jump to Official Photos and Info – 2018 Dodge Challenger SRT Demon .

Filed to: 2018 Dodge Challenger SRT Demon . The Demon will do the quarter mile in 9.65 seconds at 140 MPH, but if you keep that down to 9.99 seconds or worse and 135 MPH or slower, nobody will make you get a license or an expensive roll cage.

One hundred fifteen. That’s the number of parts in an SRT Hellcat that Dodge changes to make a Demon. Some are made lighter, some are made stronger, and some are simply removed altogether. Compared with the total number of parts that it takes to make a running car, 115 is a small number.

So is 9.65. That’s how few seconds Dodge claims the Demon needs to run a quarter-mile, blistering the trap at 140 mph. If we can match that figure—a sizable “if,” since our testing venue better approximates grip levels on the street than the drag strip where Dodge ran its numbers—it will make the Demon the quickest street car we’ve ever tested. Period. That includes million-dollar hypercars and 1000-hp aftermarket specials. It’s also quick enough that an NHRA-sanctioned drag strip will require you to install a roll cage. Indeed, SRT boss Tim Kuniskis is proud of the letter he received from the NHRA telling him his car is banned without one.

2018 Dodge Challenger SRT Demon Will Get Race Cool-Down Feature

  2018 Dodge Challenger SRT Demon Will Get Race Cool-Down Feature <p>Also getting special Performance Pages program</p>Performance Pages will be accessible through an 8.4-inch UConnect touchscreen infotainment system, and can bring up real-time graphs showing horsepower and torque; gauges for engine temperature, oil pressure, air-fuel ratio, and boost pressure; a g meter showing lateral and longitudinal g forces; and timers for reaction time, 0-60 mph, eighth mile, and quarter mile performance. Performance Pages will also feature driver-selectable line lock, rpm-adjustable launch control, and adjustability for the shift light in the gauge cluster.

It's got 840 horses, does 0-60 in 2.3 seconds, and hits the quarter -mile in 9.65 at more than 140 mph. The Demon has arrived. At a pier on the west side of New York City, Dodge finally unveiled the 2018 Challenger SRT Demon , the drag-racing variant of the already-outrageous SRT Hellcat.

177. SHARES. Share Tweet. Challenger names date back all the way to 1958, but it was until 1969 when the second generation was introduced that the name reached its proper stardom. The coupe was gorgeous and it was a direct rival to Mustang and Camaro.

To outrun the rules, the Demon leaves the lights at a claimed 1.8 g’s—some 50 percent harder than even the Porsche 918 Spyder—yanking its front wheels off the ground and carrying a wheelie for a few feet on its way past 60 mph just 2.3 seconds into the run. Drag racers will appreciate the 1.36-second 60-foot time; this is unabashedly a numbers car. But the story of those numbers involves a lot more than just a big figure in the horsepower column.

It starts, says Kuniskis, with the Challenger Drag Pak that, like the Chevrolet COPO Camaro and the Ford Mustang Cobra Jet, is a purpose-built drag car. It has no VIN and is not street legal, and it’s sold only through dealership parts departments. Says Kuniskis: “They’re $100,000 cars that you’ve got to put another $50,000 to $100,000 into to be really competitive. They’re cool cars—they’re eight-second cars—but they’re very, very limited in their scope.” So, at a time when the consumer versions of the Camaro and Mustang are increasingly pushing into sports-car territory with the ZL1 and GT350, his team seized on the opportunity to do something different. “Everyone else is going sports car,” he says, “so we decided to build the first-ever purpose-built drag car, but with a VIN and a warranty.”

Dodge reveals a few of the goodies in the Demon crate

  Dodge reveals a few of the goodies in the Demon crate There's a selection of Snap-On tools inside.One of the teaser trailers for the eagerly anticipated Dodge Challenger Demon featured a big crate full of goodies for the car. As with the car, though, Dodge was a bit coy about what was inside, simply saying there were 18 items, consisting of tools and parts. Now we know what tools the car gets, and they're some very nice Snap-On pieces.

Dodge unveiled what it claims is the fastest muscle car ever: the 2018 Challenger SRT Demon with a devil of a kick—808 Quarter mile in 9.65 seconds and 140 mph, which means it is legally banned from racing on a track without a rollcage. 2018 Dodge Challenger News and Reviews. Motor Trend.

It sounds like they're talking about the quarter -mile, and maybe about the somewhat-illicit practice of racing for pink slips? A post shared by Ill Mac (@illegal_machine) on Jan 17, 2017 at 6:37am PST. 2018 Dodge Challenger SRT Demon with the Included (Race Gas) Button.

Race cars are stripped down, and so, too, is the Demon. Chucking the rear bench saves 55 pounds. The front-passenger chair, with all those levers and gears allowing finicky people to adjust it to their comfort, takes 58 pounds with it as it goes, leaving the driver alone with his thoughts. (Both seats can be added back in as options for $1 apiece.) All the speakers are gone, except for two that hang around to sound the seatbelt-warning chime required by law. The associated wiring and simplified head unit account for a 24-pound savings. Yanking the trunk trim saves 20 pounds, and Kuniskis says his team begrudgingly left some sound deadening in the firewall but chucked it from the rest of the car. “There are a couple pieces we had to leave, but we Swiss-cheesed ‘em.” That saved another 18 pounds and makes for a car that he says sounds “wicked.” He adds: “If you don’t like the sound of a supercharger, you won’t like this car. The thing howls in your ear when you’re driving.”

Downsizing the wheels from 20 inches to 18 saved another 16 pounds, as did shrinking the front brakes. Switching to hollow anti-roll bars saves 19. Smaller savings come from ditching the parking sensors and the power tilting/telescoping steering mechanisms (the adjustments are manual now). All told, the Demon is some 215 pounds lighter than a Hellcat.

2018 Dodge Challenger SRT Demon Gets Torque Reserve System

  2018 Dodge Challenger SRT Demon Gets Torque Reserve System <p>Helps with launches and produces unique exhaust note</p>Dodge says the Demon's unique exhaust sound is the product of an advanced torque reserve launch system—the first ever designed for drag racing in a production car. This system allows more air to flow through the engine before launch, building rpms in the supercharger without overwhelming the brakes and spinning the tires. Torque reserve is triggered when Launch Mode is selected and engine speed is greater than 1,000 rpm.

Launching at 1.8 g’s requires an efficient transfer of that lightened load rearward, which means softer springs, noodlier anti-roll bars, and adjustable dampers that behave differently here than in any other car. “Every single adaptive suspension ever made has a baseline,” notes Kuniskis. “And the idea is to take it from the baseline to stiffer, stiffer, stiffer. Street, sport, track, whatever.” But, since drag racers on a budget have been known to drill holes in their front dampers to drain the fluid—facilitating quicker load transfer to the rear on launch—the SRT team tuned the adaptive dampers from the Hellcat to do the modern equivalent. At launch, the rears go full firm, and the fronts soften completely—so long as the driver keeps the throttle wide open. If the car gets squirrelly and the driver backs out of the gas, the fronts firm up to help maintain directional control as load shifts back onto the skinny front tires.

Dodge Challenger SRT Demon TransBrake eliminates the need for torque braking

  Dodge Challenger SRT Demon TransBrake eliminates the need for torque braking A new system is installed to help launch the Demon.According to Dodge, the main benefit of TransBrake versus a two-foot setup is a quicker power delivery and higher engine launch torque potential. The system gives brake-free launches up to 2,350 RPM, a 105-percent increase in launch boost pressures, and a 120-percent increase engine launch torque. Dodge also claims that the using the paddle provides a 30-percent better reaction when compared to using your feet.

Those tires, known as “runners” in the drag-racing world, are part of a gymnastic loophole squirm Dodge had to perform to get the Demon past its own lawyers. They are not street legal, which is why, when buyers pick up their Demon from the dealership, it will ride on four identical Nitto NT05R drag radials, 315/40R-18 at each corner. The car will come with a voucher that entitles the buyer to purchase a big box called the Demon Crate from the parts department; like the seats, the Demon Crate option costs $1. In it are, among other things, a pair of 4.5-inch-wide wheels along with a jack, a Snap-on electric impact wrench, and a torque wrench so the owner can fit them to the car. Critically, though, the crate is sold separately from the car and doesn’t even come with tires. “The wheels don’t come with the car, they’re not on the car, and we don’t even give you the tires,” says Kuniskis. What lawyer could possibly object? And, while the crate is far too large to fit in the Demon, it also contains a foam carrier that nestles into the spare-tire well and has cutouts to transport all the critical bits to and from the track. So, yes, those Nittos on the front axle when the Demon grumbles out of the showroom are rear spares.

2018 Dodge Challenger SRT Demon© Michael Simari and the Manufacturer 2018 Dodge Challenger SRT Demon

The drag radials are rated for only 168 mph, which is why the Demon is governed where the less powerful Hellcat is free to run to 199. A Demon logo molded into the sidewall proves the Nittos aren’t off-the-shelf rubber. Near-slicks, they have just enough tread to be street legal and are designed to run lower pressures to allow the sidewall to wrinkle at launch for that last shred of grip. A devil-tail index mark stamped into the wheels helps ensure that they’re not running too little pressure. Simply make a mark on the tire next to the tail before a pass; if it moves relative to the tail, your wheels are spinning inside the tires, and you need to add air.

Wider by 1.7 inches than the rubber on a Hellcat, these tires are the reason for the Demon’s menacing fender flares, which widen the body by 3.5 inches and do much to visually shrink the Challenger. Up front, where they wrap around the fender creases, they seem to pull the hood toward the ground. Out back, they break up the vast acreage of sheetmetal that is the rear-quarters and, coupled with the higher-series slicks on black wheels, add a measure of menace otherwise absent from the Hellcat’s haunches.

There’s more legal sleight of hand in the weaponized powerplant, which makes 808 horsepower and 717 pound-feet of torque. But that’s on pump gas. In addition to the wheel-swapping kit, the Demon Crate contains a replacement engine controller that contains programming for race fuel and a new climate-control panel with a 100-octane button. On high-test, the Demon will make 840 horsepower and 770 pound-feet of torque.

Just as “Hellcat” refers both to the car and the engine, so, too, does “Demon.” And while the Hellcat engine has an orange block, the Demon’s is red. Only the block and the heads are shared between the two; Dodge isn’t saying yet how the engine’s internals are fortified, but everything from the crank to the valvetrain has been beefed up to handle the extra output. The supercharger grows from 2.4 to 2.7 liters, with max boost climbing from 11.6 to 14.5 psi.

To meet the airflow needs of such a brute, the Demon gets a new hood with a larger scoop. The Hellcat has had its innermost driver’s-side headlight hollowed out and ducted into the airbox; the Demon gets that same treatment, plus its passenger’s-side light becomes a similar void.

As colder air makes more power, Dodge added what it calls the After-Run Chiller, which runs the fans and pump to keep the coolant circulating, aggressively bringing the intercooler temp back down to ambient. Then the SRT team took it one step further, plugging an additional heat exchanger into the intercooler’s fluid circuit that allows them to use the air conditioner to super-chill the coolant as much as 45 degrees below ambient temperature. “On a muggy 80-degree day,” says Kuniskis, “your car thinks it’s in Alaska.”

A torque-management system cuts fuel to random cylinders and retards the timing when the car is in Launch mode, allowing the Demon to spin up its supercharger and stuff the engine full of boost. The staccato soundtrack that results is a bit of bonus drag-strip theater.

2018 Dodge Challenger SRT Demon© Manufacturer 2018 Dodge Challenger SRT Demon

Incredibly, the ZF eight-speed in the Demon remains unchanged. It gets a trans brake and a higher-stall torque converter that is tweaked for additional torque multiplication, but the gear ratios even carry over from the Hellcat. Everything aft of the transmission is beefed up, though. The driveshaft tubing is 20 percent thicker, the differential gets a higher-strength gearset and a sturdier case, and the half-shafts are fortified. A shorter 3.09:1 final-drive ratio (compared with the Hellcat’s 2.62) better matches the engine speed to the Demon’s single-minded mission of Christmas-tree racing.

To encourage the driver to keep that mission in focus, the Demon also includes a number of new infotainment features. A real-time display of horsepower and torque output will try to distract you as you manage the real-world implications of that output, while a data-recording feature will generate a log of runs. It helps track any performance changes due to anything from shifting weather to new parts. You can adjust your launch-control rpm and handicap your reaction time by customizing the timing of the shift light for each individual gear, or just keep an eye on things with digital gauges for oil pressure and temperature; coolant, trans fluid, intake-air, and intercooler temps; the air-fuel ratio; the supercharger boost; and the battery voltage. Another screen plots the effectiveness of the After-Run Chiller and tells you precisely when the car is ready for another full-power pass. Still others will clock your zero-to-60, zero-to-100, and eighth- and quarter-mile times as well as your reaction time against an in-car countdown.

2018 Dodge Challenger SRT Demon© Michael Simari and the Manufacturer 2018 Dodge Challenger SRT Demon

As thorough and as uncompromising a rethink as the Demon is, it won’t be a huge step up in price from the Hellcat. It starts at $86,090, although dealers shouldn’t have a hard time finding people to pay many tens of thousands more. Dodge will crank out 3000 Demons for U.S. customers and an additional 300 for Canadians. Deliveries begin this fall.

The Demon, while obviously a numbers car, is about something else beyond numbers. It’s about headlines. Kuniskis stresses the importance of the Demon being the ultimate. “If the car ran 10.2 seconds and it was not banned, and it was not the quickest, that’d be great, but nobody would care because it wasn’t the quickest zero to 60, it wasn’t the quickest quarter-mile, it wasn’t banned, and it didn’t do a wheelie. But when it does all those things, that’s when people go: ‘Wow, what just happened? That Bugatti is supposed to do that, not a Dodge.’”

Explained: The Demon’s Transmission Brake

A trans brake is a common drag-racing device that helps a car launch harder. When activated, it simultaneously engages first and reverse gears, locking the transmission’s input and output shafts and preventing the car from moving. It’s like brake-torquing but removes the risk of doing a burnout or, at the strip, pushing those skinny front tires through the staging lights. It also allows the engine to hold higher revs, which means that the car can launch at precisely the torque converter’s stall speed. In a supercharged car such as the Demon, that also allows the blower to build boost before launch. And since most people’s hands are quicker than their feet, and the driver releases the transmission brake by pulling either shift paddle, it should help reaction times at the strip as well.
