Dodge challenger SRT demon 2017-2018

SRT Demon[edit]
Dodge Challenger Demon at the 2018 Geneva Motor Show

The Demon is a limited production wide body and extreme (drag race level) performance variant of the already high performance Challenger SRT Hellcat. It debuted as the fastest and most powerful production car in the world[62][63] during the New York Auto Show in April 2017.[64]

The Demon uses an all-new 6.2-liter V8 engine equipped with a 2.7-liter supercharger, which is rated at 808 hp (603 kW; 819 PS) with 91 octane gasoline and 840 hp (626 kW; 852 PS) with 100 octane fuel or higher (both outputs are with the red key fob supplied with the car). Torque stands at 770 lb⋅ft (1,044 N⋅m) on 100 octane fuel. The car weighs 215 lb (98 kg) less than the Hellcat, the total being 4,254 lb (1,930 kg). The SRT Demon uses a set of road tires by Nitto Tire, called the NT05R. The tires are the 315/40R18 variations at both front and rear. The tires are targeted for the drag strip, but have enough tread pattern to make them legal for the road. This tire, although an NT05R consumer tire, is a variation built specifically to withstand the power output of the Demon. This makes the Challenger SRT Demon the first production car to contain a set of drag radial road tires.[65] The SRT Demon contains a system that is used specifically for drag racing called transbrake, which is a mechanism that puts the transmission in 1st gear and the reverse gear simultaneously, holding the Demon stationary.[66] This is used along with the car's torque converter to build up hydraulic pressure before launch.

The power-to-weight ratio of the SRT Demon is 418 hp (312 kW; 424 PS) per ton on 91 octane gasoline and 435 hp (324 kW; 441 PS) per ton on 100 octane or higher.

The SRT Demon accelerates from 0–30 mph (0–48 km/h) in 1.0 second, 0–60 mph (0–97 km/h) in 2.3 seconds (2.0s with a rollout), 0–100 mph (0–161 km/h) in 5.1 seconds, a top speed of 168 mph (270 km/h) (factory limited), and the quarter mile (400 m) in only 9.65 seconds at 140.09 mph (225.45 km/h).[67] This makes the Demon the fastest non-electric production car to reach 0-60 mph (0–97 km/h) and to complete a straight-line quarter mile at its time of announcement. The SRT Demon is also capable of accelerating at 1.8 G's of force at launch, making this the hardest launching production car.[68] The boost pressure of the supercharger can be increased to 14.5 psi and redline up to 6,500 rpm. With this extreme power, and hard acceleration, the SRT Demon is the first production car to perform a wheelie.[69] With the control module from the "Demon Crate" and high-speed tires, the Demon has attained a top speed of over 200 mph (320 km/h) in test runs.[70]

Because of the lack of an NHRA certified roll cage, which is required if the quarter mile time is under 10 seconds, the NHRA banned the SRT Demon from competition.[71]

Like the SRT Hellcat, it comes with both red and black key fobs, with the black fob limiting the power output to 500 hp (373 kW). With the red key and the use of 100+ octane gasoline, the Demon can utilize its full power potential. Only 3,300 cars were made, with production beginning in the summer of 2017 and market introduction happning in the fall of 2017.[72][73]

The interior of the SRT Demon is the same as all other Challenger trims, but with changes that differentiate it to the other trims. The Demon only includes a front driver's seat as standard, and no other seats front or rear in the vehicle. However, the front passenger's seat, as well as a rear bench seat, can both be added back as options for one dollar each. To replace the rear seats, Dodge included rear roll bars, and has a 4-point harness installed on it for the driver seat.[74] The dashboard display and the seats now have the Demon logo on them,[75][76] and includes a performance display on it, as well as on the center console touch screen.[77]

The following list below is a breakdown of how Dodge engineers reduced the curb weight of the 2018 Challenger SRT Demon to 1,930 kg (4,255 lb) over the 2,027 kg (4,469 lb) curb weight of the SRT Hellcat, a difference of 98 kg (216 lb):[78] [79]
