When exploring the Dodge Challenger SRT Hellcat, enthusiasts often ask about its real-world performance—specifically, its wheel horsepower (whp). Understanding the whp is crucial as it represents the power available to propel the car forward after accounting for losses in the drivetrain. Traditionally, manufacturers list power in terms of brake horsepower (bhp), which is measured at the engine crankshaft, leading to an inevitable question: How does this translate to the power actually reaching the wheels?
On average, stock Hellcats are measured to produce around 630 whp on dynamometers. This figure factors in the commonly accepted drivetrain loss of approximately 12%, revealing a close alignment with the 707 bhp that Dodge (a brand under the Stellantis umbrella, previously known as Chrysler) advertises. This synergy between reported bhp and observed whp underscores the Hellcat’s reputation as a muscle car that delivers on manufacturer promises. The SRT Hellcat’s engine potency has solidified its status in the pantheon of high-performance American cars.
Design and Features
The wheels are another pivotal aspect of the Hellcat’s design. They are engineered not just for looks but also for performance, supporting the car’s substantial weight without compromising agility. Opting for the widebody variant involves upgrades in the wheel department, which complement the increase in vehicle width.
| Feature | Benefit | Details |
| Widebody Option | Enhanced Traction | Wider tires and fender flares |
| Wheels | Performance Support | Engineered for weight and agility |
We observe that the design doesn’t just stop at performance and aesthetics; it extends to features that enhance the driving experience. Mentioning the roof and decklid, it’s clear that attention to aerodynamics plays a role, optimizing both speed and fuel efficiency.
In terms of features, the Hellcat is well-appointed. While the focus is often on the powerhouse under the hood, it’s important to recognize the features that support the driver. Reliable brakes, a sturdy suspension system, and a raft of safety features ensure that the Hellcat’s power is matched by an equal measure of control. We appreciate the blend of raw power with the finesse of modern automotive engineering tucked into every aspect of the Hellcat’s design and features.
Performance and Specifications
We will showcase the Dodge Challenger SRT Hellcat’s engineering prowess, detailing its high-performance attributes.
Engine and Horsepower
Supercharged 6.2L HEMI® SRT Hellcat V8 Engine
The Hellcat’s heartbeat is a supercharged 6.2L HEMI V8. It generates an impressive 630 wheel horsepower (whp) on average, which nearly aligns with its 707 brake horsepower (bhp) as advertised by FCA once corrected for drivetrain loss. The supercharger plays a critical role, supplying a significant boost to maximize power output.
Transmission and Drivetrain
Our Hellcat models come equipped with a TorqueFlite® 8-speed automatic transmission which provides rapid shifting and contributes to the balance between performance and comfort. The drivetrain is tuned to manage the immense torque output with a rear-wheel-drive setup, which requires strategic traction control to harness effectively.
Speed and Acceleration
Acceleration: 0-60 mph in mid-3 seconds range.
Speed and acceleration are paramount. The Hellcat achieves 0-60 mph in the mid-3 seconds range and can reach a top speed of around 203 mph. It is equipped with a transbrake for optimal launch control, ensuring each acceleration is as explosive and controlled as the last.
Handling and Traction
Handling and traction are critical for maintaining control. Our Hellcat models feature widebody kits that not only enhance their visual impact but also improve grip by accommodating wider tires. The suspension system and electronic stability control are fine-tuned to handle high speeds while ensuring that traction is not just a mere afterthought.
| Feature | Specification | Impact |
| Widebody Kit | Flared Fenders | Improved Road Grip |
| Suspension | High-Performance Tuning | Stability at High Speed |
Models and Variants
In this section, we’re exploring the different models and variants of the Dodge Hellcat series. Each variant offers a unique combination of power, performance, and design to cater to different driving enthusiasts.
Challenger SRT Hellcat
The Dodge Challenger SRT Hellcat is a legendary production vehicle in the muscle car world. It is available with a Widebody package, which enhances its aggressive stance and track capabilities. With strong performance figures stemming from its supercharged V8 engine, the Challenger SRT Hellcat has become a benchmark for power among American sports cars.
Charger SRT Hellcat
Dodge’s four-door powerhouse, the Charger SRT Hellcat, offers a rare blend of monstrous horsepower and family-friendly usability. It shares the supercharged V8 engine with the Challenger, and also offers a Widebody option for greater grip and an even more imposing look on the road. This model defines the peak of performance for four-door sedans.
