Dodge has just dropped an exclamation mark on the end of its gas-powered muscle car era.
On Tuesday, the company that brought you the Hellcat and Demon stepped up itself with the reveal of the 2023 Dodge Challenger SRT Demon 170. It’s the seventh and last “Last Call” special edition model before the lights go out for the era.
Production will begin this summer and each Demon 170 will cost $100,361, including a $1,595 destination fee and a $2,100 fuel guzzle fee. The MSRP is a wicked $96,666.

Satan 170 performance number
The Demon 170 turns things up to an 11. Peak output on the E85 is rated at 1,025 hp and 945 lb-ft of torque. Filling the tank with premium fuel (E10) drops power output to 900 hp and 810 lb-ft. It can also run on a combination of the two because the electronics automatically determine the percentage of ethanol in the fuel and recalibrate the engine to run accordingly. The name Demon 170 is a riff on the E85 fuel’s 170 proof rating. The Hellephant C170 crate machine carries its name for the same reason.
Dodge says the Demon 170 launches from 0-60 mph in 1.66 seconds and pulls 2.0 g of track on a launch-prepared surface. On an unprepared dragstrip, it’ll still make a 0-60 mph run in less than 2.0 seconds, though Dodge CEO Tim Kuniskis notes it won’t go on the road.
It ripped the quarter mile in an NHRA-certified 8.91 seconds at 151.17 mph, and its 60-foot time was 1.20 seconds.
The Dodge Demon 170 is the fastest accelerating and fastest production car money can buy.
As a point of reference, the Demon has 840 hp and 770 lb-ft of torque on the E85, ran the quarter mile in 9.65 seconds at 140 mph, pulled 1.8 g during acceleration, and clocked a 0-60 mph time of 2.3 seconds.
The NHRA has awarded the Demon 170 a violation letter for his ability to run a sub-nine-second quarter mile. As soon as it drops below 10 seconds it needs a safety cage and during a nine second eclipse it needs a parachute, both of which can result in a ban until the item is added.

Demon 170 engine
Dodge began developing the Demon 170 as a modified Challenger Demon but with a goal of four-figure horsepower. Kuniskis said the team ended up replacing much more than planned because the engine continued to explode. The only internal parts of the engine still shared with the Demon are the camshaft, valve springs and lifters.
The Demon’s 6.2 liter V-8 cast iron block had to be modified for the Demon 170 duty with studs for higher clamping force to the heads to allow for higher cylinder pressures. Engineers swapped the Demon’s 2.8-liter supercharger for a 3.0-liter supercharger that produces 21.3 psi. A modified version of the Hellephant supercharger, it is powered by a new 105mm throttle body connected to a 3.02-inch pulley. New studs hold the cylinder head in place to provide greater clamping force. The cylinder head is rated at 2,500 psi at E85. It was about 25% higher than a Demon in the gas race and 50% higher than Hellcat Red Eye. The engine also features new pistons, rods, nitride-coated intake valves, valve guides, crank, billet main cap, spark plugs, and an improved crank damper.
The SRT Power Chiller system developed for the Demon was carried over to the Demon 170. It reduced induction air temperatures by up to 45 degrees by switching the air conditioning system to cool the supercharger intercoolers both before and after running on the dragstrip.
The fuel rail and injector systems were upgraded to handle the change to the E85’s capabilities. The system delivers 25% more fuel through the injectors which flow up to 164 gallons per hour. “You can drain the tank in 5.75 minutes,” says Kuniskis.
The Demon’s 8-speed automatic transmission has an updated output flange to accommodate the larger diameter support shaft that is 30% stronger than the Demon’s. This is connected to a 240mm rear differential and a larger CV-linkage with a revised housing geometry. That rear differential now uses pressure instead of flow, which makes it 50% stronger than the Demon’s rear differential. A new 43-spline rear half axle was swapped out for a larger inner connecting spline to ensure things didn’t snap under torque during launch.
Kuniskis noted Demon’s TransBrake was complicated hardware and the team redesigned the system calling it version 2.0 for a better user interface. Car electronics can also work with TransBrake to dial back a certain percentage of torque in tenth-second intervals to aid tire grip; this works along the track to prevent the tire from slipping between the gears. TransBrake now allows users to choose from a variety of launch profiles to match the engine’s power delivery for tracks and conditions. There is also a memory function which allows the driver to store launch and shift out settings for the grip of various surfaces. This system allows TransBrake to increase engine acceleration up to 2,350 rpm. The Line Lock, Launch Control, and Launch Assist functions are all carried over from the Demon.

Demon 170 suspension
The Demon’s suspension has been electronically and mechanically recalibrated for the Demon 170’s duties. The Demon can catapult the wheelie then slam the front end back to earth, but the Demon 170 misses the step slam back to earth. New suspension adjustments resulted in a slower lifting front end, which gave the car more energy to move forward. The rear suspension is 50% firmer than the Demon to help cram the tires into the track and keep them tangled when hooked.
Bilstein’s Adaptive shocks remain, but are equipped with the Demon 170’s special valve adjustment, which increases rear ride height by 0.4 inches and limits rear joounce travel by 0.7 inches. Both of these changes were made to ensure that the large Mickey Thompsons were cleaned up on the rear.
Rear suspension camber revised to increase contact patch under load. The front springs are softened 35% at the front and 28% at the rear, while the front and rear sway bars are 75% and 44% softer respectively than the Hellcat Redeye Widebody.
The Demon 170 rolled over on staggered tires. The smaller 18×8-inch wheels wrapped in Mickey Thompson 245/55 ET Street tires are mounted up front, and the rear features 17×11-inch wheels wrapped in Mickey Thompson P315/50R ET Street R drag radials. Dodge worked with Mickey Thompson to ensure the rear tires had the added curve. to help performance on the road.
Street legal setup of wheels and tires, so cars can be driven from the garage to the drag strip, run on the track, then driven home. No front runners are required, and no tire and wheel changes are required on the track.
Kuniskis notes these tires should not be used in cold weather, rain or with any moisture on the ground. Dodge will require the purchaser to sign a notarized document certifying that they understand these safety details.
How much does the Demon 170 weigh?
Kuniskis says the Demon 170 is slightly heavier than the Demon, even with the optional two-piece carbon fiber wheels. The supercharger adds another 5 pounds, the throttle body adds about 1 pound, and the all-in-one Demon 170 is about 25 pounds heavier than the original Demon.
For reference, the Demon was originally said to weigh 4,250 pounds, which makes the Demon 170 weigh around 4,275 pounds.

What’s the Demon 170 like?
At first glance you might think the Demon 170 is a Demon. But take a closer look.
The rear fender flares remained but the front was dropped. Removing the front flare and lowering the front wheel from 315 to 245 saved 16 pounds in weight.
But the Demon 170 shares its body panels with the Hellcat and other wide-body Demons. It also features a Demon air capture hood.
The Demon badge on the front fender bears the 170 logo as well as yellow eyes to represent the capabilities of the E85.
Inside, the Demon 170 is standard Challenger SRT fare but with seating for one. To keep weight down, there’s no front passenger seat, no back seat, no boot mat, no sound insulation, and no trunk light. The radio only has two speakers, and Dodge outfitted the car with a Demon 170 custom gauge cluster display and a Demon 170 dash plaque.
Demon option 170
Dodge will not be offering the $1 option like with the Demon nor will there be a Demon Supply option. Kuniskis insists that there won’t be a cheap option.
The premium interior package will add heated and ventilated leather front seats, leather-trimmed rear seats and an 18-speaker Harman Kardon audio system. The rear seat can be removed with this package.
The sunroof is a $10,000 option. “You want a sunroof, you’re going to pay for it,” says Kuniskis.
Through Dodge’s Direct Connection Demon 170 program buyers could choose between a chute and a roll cage, both of which would ensure their cars were legal in the eyes of the NHRA to run in the ‘8s. CO2 bottles will be an option via Direct Connection.
For Hellcat or Demon owners looking to upgrade their car, Dodge will sell the Demon 170 rear cradle, driveshaft, throttle body, and countless other bits through its Direct Connection performance parts program.
A trick set of two-piece carbon fiber wheels from Lacks Enterprises will be on the options order sheet. Buyers who tick this box will shave £11.98 off the rear end and £20.12 off the front end compared to stock running Hellcat Redeye Widebody 315s.

Since no Demon 170 crate was available, Dodge provided every Demon 170 buyer with a custom Demon-style decanter with the name and vehicle VIN engraved on it, coasters and Demon-badged whiskey cubes, a rock glass, a Demon 170 supercharger badge cover, a VIN plate, and illustration of Demon 170.
How to order Demon 170
Using the Dodge Horsepower Finder tool, buyers looking for a Demon 170 can find which dealer will have an allocation and check prices.
Orders will be taken from March 27th with the order book closing on May 15th.
Dodge won’t prevent dealers from marking the Demon 170, but orders at MSRP will receive a priority build slot.
Any Demon owner who gets the Demon 170 build slot will be offered the chance to match their car’s VIN.
How many Demon 170 will be made?
Kuniskis says Dodge is aiming to build 3,000 Demon 170s for the US and 300 for Canada, which is the same number built for the Demon.
But the executive was quick to note that he wasn’t sure if Dodge would be able to come up with those numbers. Between downtime at the factory, parts shortages and other issues, the team hopes to initially issue an allocation of around 2,500 or 2,700 and continue from there. After December 31, production ceased regardless of the number of Demon 170s built.
Every Demon will come with a standard 3 year/36,000 mile Dodge warranty.
