The new Dodge Charger R/T Scat Pack’s chassis

0

The all-new Dodge Charger R/T Scat Pack is engineered with a high-performance tuned chassis – designed with the hardware necessary for high-demanding track conditions.

Exclusive Bilstein high-performance shock absorbers are highly damped and provide a firm ride that maintains the feel for everyday commuting while being capable for the more challenging situations. Additionally, the Charger R/T Scat Pack features specific suspension geometry to improve balance, cornering ability and steering responsiveness. For improved handling, the suspension has been lowered 0.5 inch (1.3 cm). The result: the Dodge Charger R/T Scat Pack is capable of 0.88g on the skid pad.

With four-piston Brembo calipers lacquered in black at each corner with 14.2 inch (front) and 13.8 inch (rear) vented/slotted rotors, the Dodge Charger R/T Scat Pack reaches a braking distance of 60-0 mph in 120 feet (100 km/h to 0 in 37 meters). Improved brake cooling and fade performance comes courtesy of wind tunnel designed brake cooling ducts that direct airflow to the vented rotors for consistent stopping power.

Tying the chassis upgrades together are new 20-inch lightweight alloy wheels with Goodyear Eagle F1 three-season performance tires. For those who live in colder climates, Goodyear Eagle RS-A all-season performance tires are a no-charge option.

Dodge Charger 2015

RWD architecture with advanced technological solutions

As the Dodge brand’s performance flagship, the chassis of the all-new 2015 Dodge Charger is designed, engineered and fine-tuned to deliver world-class performance and efficiencies – thanks to its advanced technological solutions.

Super Track Pak – exclusive equipment on 2015 Charger R/T Road & Track

The 2015 Charger R/T Road & Track model delivers with the Super Track Pak equipment standard. The Super Track Pak elevates the standard Dodge Charger R/T model’s sport-tuned suspension and braking by adding performance suspension tuning, a high-performance brake package, high-performance steering, 3.07 rear-axle ratio and 20-by-8-inch dual five-spoke polished cast-aluminum wheels with black painted pockets and P245/45ZR20 BSW all-season performance tires (optional Goodyear F1 three-season tires). The package also includes Dodge Performance Pages.

All-new advanced electric power steering system

The 2015 Dodge Charger features an advanced steering-column-mounted electric power steering (EPS) system that improves both handling and performance. The vehicle uses the latest EPS system technology available, which delivers sporty handling by managing significant loads at all steering wheel operating speeds, power assist curves modulated according to driving conditions and up to a 3 percent improvement in fuel efficiency, when compared with a conventional hydraulic system.

All of the power boost, or assist, is provided via an electric motor.

New, lighter weight axles for RWD and AWD

The 2015 Dodge Charger RWD and AWD models feature all-new cast-aluminum axles and housing. Replacing the previous steel structure, the new aluminum axles and housing help to reduce weight. The new driveline is also designed to reduce parasitic friction and increase durability with a new four-bolt design (previously a three-bolt design).

Lightweight front suspension cradle

At the heart of the 2015 Dodge Charger’s front suspension is a rigid and lightweight suspension cradle made from tubular steel, which features hydro-engine mounts to make the interior cabin smooth, comfortable and quiet. Premium hydro-bushings, monotube shock absorbers and a lower-front-shock-to-suspension-link bushing provide control, ride and comfort.

Rail-like cornering with roll-steer multilink rear suspension

Dodge Charger’s five-link rear suspension design features roll-steer geometry to allow independent control of camber and toe suspension movement. The rear suspension cradle is the main attachment point for the Dodge Charger’s five-link independent rear suspension system. Using rubber mounts, this hydro-formed steel cradle provides an additional structure to isolate the passenger compartment from road and axle noise, vibration and harshness (NVH). Monotube shock absorbers, urethane jounce bumpers and suspension links with rubber shock absorber bushings all work together. Upper and lower spring-seat isolators provide additional damping to deliver smooth suspension engagement over bumps.

Aggressive front- and rear-camber geometry

Performance handling requires maximum road-holding grip, and the Dodge Charger delivers with aggressive front- and rear-camber geometry. Set at -1.0 degrees in the front and -1.75 degrees in the rear, Dodge Charger is set up for high-speed cornering with its tires leaning inboard at the top relative to the body.

Romain’s opinion:
Designing the chassis of a sporty Sedan is not an easy thing. You have to strongly trade-off the comfort that can be expected for such a big car, with its induced weight and the wanted vehicle dynamics behavior. Do you think that the Dodge Charger R/T can rival a coupe that has the same power and torque in terms of cornering speed and vehicle dynamics? What could be the results of race between this Dodge Charger and the Chevrolet Corvette on the Laguna Seca track for example?
