History of the Hemi V-8

The HEMI V8 engine made its first significant impact in 1951, debuting as the 331-cubic-inch "FirePower" V8 under the hood of Chrysler's luxury models. What set it apart wasn't just the power, but how it delivered it, thanks to its hemispherical combustion chambers that allowed for larger valves and more efficient airflow. By 1953, HEMI engines were dominating NASCAR, prompting competitors to scramble to catch up. Then came the 426 HEMI in 1964—nicknamed the "Elephant Engine" due to its size and strength—which became a legend in drag racing, particularly in the Super Stock and Top Fuel classes. Chrysler built the HEMI not just to compete, but to win, and win it did, both on the track and on the street.

At the heart of every HEMI engine is a hemispherical combustion chamber, which creates a more complete and even burn of the air-fuel mixture. That design leads to improved thermal efficiency, allowing these engines to produce more horsepower per cubic inch than many of their competitors. The layout also accommodates larger intake and exhaust valves, allowing the engine to breathe more efficiently at high RPMs. Over the years, Chrysler's engineers have enhanced the design with technologies such as dual spark plugs and variable valve timing. It's not just about raw numbers—although those are impressive too, with modern 6.4L HEMI engines putting out over 470 horsepower—it's about the distinct power curve and throttle response that you feel every time you step on the gas.

Despite the oil crises and emissions crackdowns of the 1970s, the legend of the HEMI lived on. The original 426 HEMI was retired in 1971, but by 2003, Chrysler brought it back in a new form—the 5.7L HEMI. This modern version debuted in the Ram 1500 and quickly spread to other vehicles like the Dodge Durango, Charger, and Challenger. It featured aluminum heads, a coil-on-plug ignition system, and a Multi-Displacement System (MDS) that deactivates cylinders at cruising speeds to improve fuel economy. By the 2010s, the HEMI lineup expanded again with the introduction of the 6.4L (392) HEMI and the supercharged 6.2L Hellcat variant, which produced over 700 horsepower in some models. Through all this evolution, the HEMI continued to represent strength, resilience, and unrelenting performance.

Now, the 2026 Ram 1500 is gearing up to bring back what many fans have been asking for—the return of the HEMI V8. While Ram's latest models have embraced the Hurricane twin-turbo inline-six and mild hybrid systems, the brand knows that nothing stirs the soul of a truck enthusiast quite like a naturally aspirated V8. The 2026 Ram will feature an updated version of the 5.7-liter HEMI, known for its robust 395 horsepower and 410 lb-ft of torque, paired with improved fuel management tech and a more refined transmission setup. Whether you're towing heavy loads, heading off-road, or want that unmistakable V8 rumble, this Ram will deliver. And when it arrives, you'll be able to find it right here at Gillman Chrysler Jeep Dodge Ram—ready to turn heads and haul just about anything you throw its way.

The HEMI V8 is an icon that's been roaring through American roads, race tracks, and job sites for over 70 years. From its roots in 1950s motorsports to its modern-day dominance in trucks and muscle cars, the HEMI has always stood for unmatched strength, performance, and engineering brilliance.
