Dodge//SRT is working on one last hurray for its supercharged HEMI program!

Dodge//SRT rocked the high-performance automotive world in 2014 with the launch of the 2015 Dodge Challenger SRT Hellcat with 707 horsepower. The launch kicked off a great trend of supercar performance muscle cars at a price the average person could afford.

In 2017, the American automaker shook the foundations of the entire performance industry again with the unveiling of the limited-edition 2018 Dodge Challenger SRT Demon. An 840 horsepower street-legal drag racing machine that can dominate the drag strip. The Challenger SRT Demon became an instant legend, thanks to a NHRA-certified pass of 9.65 seconds at 140 mph, making the Demon the fastest 1/4-mile mass-production car in the world.

The Challenger SRT Demon was the first-ever road-legal factory production car designed to run on over 100 high-octane unleaded gasoline. That fuel is readily available at select gas stations, specialty stores, and drag strips. In order to unleash the high-octane mode, an owner would have had to purchase the available Demon Crate, as the Direct Connection Performance parts included in the kit included a new powertrain control module calibrated for the high-octane unleaded fuel and a new swap bank for the center console with a high-octane button.

The SRT Demon left the factory with a powertrain control module configured for premium 91-octane unleaded fuel pump that delivers peak performance. The switch to the Direct Connection controller enabled the supercharged 6.2-litre HEMI Demon V8 engine to extract maximum power from the knock-resistant fuel at high pressures and optimal spark timing.

The Challenger SRT Demon was designed to run on a mix of 100+ octane and premium unleaded fuels without damaging the engine, but the high octane feature would not activate if the combined fuel octane was too low. A message on the gauge display told the driver that the car would use the premium fuel calibration until the engine was turned off and restarted.

The final result was a boost of up to 40 horsepower and 53 lb.-ft. torque with 100+ octane in the SRT Demon’s fuel tank.

Since then, Dodge//SRT has offered a number of configurations of its approximately 800 horsepower muscle cars with the supercharged 6.2-liter HEMIĀ® Demon V8. The powerplant is featured in the SRT Hellcat Redeye, SRT Super Stock and SRT Jailbreak ranges, all of which offer roughly the same horsepower as the Demon without its magical high-octane racing fuel mode.

So where do we get to?

Dodge//SRT has said that the Hellcat era will come to an end once the next-generation Dodge Challenger (LB) and Charger (LF) hit the market in 2024. The new generation of muscle cars will be more efficient and economical. friendly internal combustion engines (ICEs) and a battery-electric vehicle (BV) powertrain that will be able to surpass the current Hellcat range.

While Dodge has announced it will show off a conceptual version of its all-new eMuscle car later this summer, that doesn’t mean Dodge//SRT isn’t working on something special for the final hurray for the supercharged HEMI in the Challenger.

According to our sources, Dodge//SRT will launch another high-performance limited-edition model before the current generation comes to an end. But what makes this new car special is that it can run on ethanol (E85) instead of 100+ octane racing fuel.

Those sources have indicated that the car should have limited production (like that of the SRT Demon) and be able to produce stronger numbers than the SRT Demon. How much horsepower we don’t know, but Mopar’s Direct Connection Stage 3 Kit for the Hellcat Redeye delivers 885 horsepower with 100+ octane, Hellephant pulley and tuning. While not confirmed, we expect horsepower to be over 850+ for the E85 tuned Challenger SRT Hellcat Redeye Widebody.

The sources also told us that the car will be part of the brand’s ‘Never Lift’ campaign, Dodge’s 24-month roadmap to the brand’s future with performance.

We hope to learn more about the car in the coming weeks. So stay tuned.
