The 2015 Dodge Challenger SRT Hellcat engine is one of the most powerful production cars ever made. With 707 horsepower, it can go from zero to 60 mph in just 3.6 seconds and can hit a top speed of 204 mph. The engine technology behind this incredible performance was developed by Chrysler’s SRT engineering team over two years and included massive amounts of computer simulations and on-road testing. Here are some fascinating facts about how they did it:
The technology behind the 707-horsepower SRT Hellcat engine
Whether you’re a gearhead or not, it’s hard to deny that the 2015 Dodge Challenger SRT Hellcat is a pretty impressive car. The 707-horsepower HEMI V8 engine has its own unique sound, and its technology can be attributed partially to Chrysler’s engineering expertise. For example, the supercharger was built by IHI Corporation in Japan and is capable of generating 15 psi (pounds per square inch), more than double what other engines require for full power output. That means less lag time between shifts—and let’s face it, who doesn’t love getting their fill of turbo boost before shifting gears?
The cylinder heads are also made with a casting process that results in superior strength and durability over equal units produced using machining techniques. This translates into crisp response time when you step on the gas pedal without worrying about head gasket issues down the line either!
The supercharged HEMI is exclusive to Dodge
The supercharged HEMI engine is exclusive to Dodge. It’s a V8 with 707 horsepower and factory-installed, track-ready suspension. The engine was created by Chrysler’s SRT engineering team and built in Michigan at the Windsor Assembly Plant. The design and build process took two years and involved massive amounts of computer simulations and on-road testing.
It’s a V8 with 707 horsepower
The Challenger SRT Hellcat is the most powerful muscle car on the market today. It has 707 horsepower and they are all supercharged. The Dodge Charger and Viper also have their own version of the Hellcat engine.
It was created by Chrysler’s SRT engineering team
The Hellcat engine was designed by the SRT engineering team. It was built by Chrysler, not Dodge, and it was built in Detroit — not at a factory in Mexico or Canada. The first Hellcat engine rolled off the assembly line at Chrysler’s Warren Truck Assembly Plant in July 2014, less than three months after a preliminary design review by SRT engineers.
The 2015 Dodge Challenger SRT Hellcat will be available in the fall of 2014
The 2015 Dodge Challenger SRT Hellcat will be available in the fall of 2014. You’ll be able to find it at your local dealership or online at [insert website here]. The engine will have 707 horsepower, and you can get it with a manual or automatic transmission.
The engine design and build process took two years and involved massive amounts of computer simulations and on-road testing.
The SRT team began by taking a close look at the existing Hellcat and its 6.2-liter V8. This engine had been in use for years, but it was time to make some changes. The first step was to redesign the cylinder heads and camshafts to get more power out of each cylinder cycle.
Then, they focused on increasing the compression ratio from 9.0:1 to 10:1 (with subsequent increases in horsepower). To do this, they raised both camshafts 0.5 inches closer to the block surface and reduced valve lift from 22mm/23mm at 0 degree to 20mm/22mm at 0 degree—all this while maintaining consistent exhaust gas velocity throughout all stages of intake event timing curves (which means less emissions).
The idea for the engine came from SRT engineers who wanted to create a car that could go as fast as a European sports car, but still look and handle like an American muscle car.

They were inspired by the idea of creating a car that could go as fast as a European sports car, but still look and handle like an American muscle car.
Several different versions of the engine were tested, including an aluminum block version, before settling on the current iron block model.
While the aluminum block version was lighter, the iron block model was more durable and had a longer lifespan. The iron block version also cost more to produce than the aluminum one. The SRT Hellcat engine is a 6.2L V8 Hemi MDS (Multi-Displacement System) that produces 707HP at 6000RPM and 650 lb/ft of torque at 4200RPM with 93 octane fuel.
The MDS system allows for two different power levels depending on driving conditions: when cruising on freeway or highway speeds it runs in all eight cylinders; however, when driven hard through corners and around town it switches to four cylinders, saving fuel while still producing plenty of power (over 600hp). This helps keep your car from constantly needing fill ups!
Making an engine with this much power required some innovation. For example, the cylinder heads are made with a casting process that results in superior strength and durability.
Making an engine with this much power required some innovation. For example, the cylinder heads are made with a casting process that results in superior strength and durability. The one-piece design is both lighter than its predecessors and helps reduce hot spots within the combustion chamber, reducing knock and improving performance.
Cylinder heads are a crucial part of any engine—they’re where air and fuel mix together to create explosive energy that drives your car forward. And while most vehicles use aluminum or iron for their cylinder heads, SRT Hellcat uses steel instead. This makes it stronger, more durable, and more reliable than other engines on the market today!
But why would anyone want to build an engine out of steel? Steel is heavier than aluminum or cast iron; therefore it takes more energy from your car’s battery pack or alternator (what we call “electrical load”) before it can rotate all those cylinders smoothly enough for smooth acceleration off the line without stalling out by itself first! That means less efficient fuel economy too—but don’t worry: We’ve got you covered there too!
The supercharger was designed by IHI to provide maximum efficiency, which means better fuel economy than you might expect from an engine with such power.
So how did the Hellcat’s supercharger become so efficient? By design, this supercharger was intended to provide maximum efficiency, which means better fuel economy than you might expect from an engine with such power. The IHI Corporation is a Japanese company that manufactures turbochargers and other engine parts. They are the world’s largest manufacturer of turbochargers and superchargers.
In order to achieve its extraordinary boost pressure without sacrificing fuel efficiency or reliability, IHI designed a twin-screw blower (similar in concept to those used on some diesel engines) with four stages rather than the usual two stages for most twin screw compressors—and it uses only one power curve throughout its range of operation. This allows for greater control over boost curves when compared with traditional single-screw compressors that have multiple power curves required by their design layouts and configurations.
You’re going to love what you can do with 707 horsepower.
You’re going to love what you can do with 707 horsepower. Here are just a few of the awesome things you can do with it:
- Go fast. The Hellcat is capable of reaching top speeds well above 200 miles per hour, and the car handles like a dream even at those ridiculous speeds.
- Go off-road. This powerful engine also has four-wheel drive, so if you want to take your car on some adventures away from the pavement and into dirt roads or trails, it’s up for anything!
- Do both at once! With such amazing power under your hood and in your tires, why stop at just one when you could be doing both?
The Hellcat engine has been in development for over two years, and we’re excited to release it this fall. It is a state of the art engine with massive amounts of power and torque that will let you do things you never thought possible in your Challenger or Charger.
