2018 Hellcat Engine Architecture
Under the hood, the 2018 Hellcat uses a factory-fortified 6.2-liter HEMI V8 that breathes through a pair of massive roots-type superchargers.
This combination generates 707 horsepower and 650 pound-feet of torque, sending power rearward through a robust 6-speed automatic transmission.
Engine internals feature forged aluminum pistons, high-flow oiling, and revised valve timing to support sustained high-R performance runs.
Exterior Design and Aerodynamics
The 2018 Hellkit carries aggressive front air shutters, a wide-body stance, and sculpted side sills that channel airflow for stability.
A functional rear spoiler and tuned suspension reduce lift at speed, allowing confident cornering at the limit without excess body roll.
Distinctive red-accent hood stripes and performance-oriented wheels underscore its track-inspired character while remaining street legal.
Interior Comfort and Technology
Inside, the 2018 Hellcat blends driver-focused ergonomics with modern infotainment, including a responsive touchscreen and available navigation.
Supportive sport seats, bolstering wing adjustments, and a flat-bottom steering wheel help channel the driver into a focused, commanding position.
Refined sound insulation, premium materials, and flexible rear seating make high-mileage trips more comfortable without diluting the performance ethos.
Performance Handling and Track Behavior
Performance-tuned shocks, thicker anti-roll bars, and larger brakes work together to tame the immense power in everyday driving and track days.
Launch Control and an electronic limited-slip differential maximize traction off the line, while traction control remains adjustable for different surfaces.
Drivers report swift turn-in and confident mid-corner balance, though the car rewards smoothness and anticipatory inputs at the edge.
