New 1-of-35 Hennessey ‘Super Venom’ Mustang Revealed

Based in Sealy, Texas, Hennessey is responsible for manufacturing groundbreaking hypercars, along with high-performance customizations of trucks, SUVs, and sports cars, all with American performance excellence at the heart of its efforts. It was 35 years ago in 1991 when John Hennessey first founded the performance firm, and a new, ultra-rare custom Ford Mustang from Hennessey has been created to mark the milestone anniversary. Since its inception, Hennessey quickly made a mark on the performance world at hallowed automotive venues like the Bonneville Salt Flats and Pikes Peak, and entered a new realm of performance in the 2000s when the record-breaking Hennessey Venom GT hypercar was unveiled. Since then, Hennessey has also unveiled the Venom GT’s successor, the Venom F5, which is still setting new standards for performance and redefining the potential of American automotive engineering. To celebrate the 35th anniversary of the brand, Hennessey has now unveiled a new ‘Super Venom’ Mustang. With several upgrades made to the 5.0-liter V8 under the Mustang’s hood, the power increased by 70 percent, going from 500 horsepower to a massive 850 horsepower. In addition, the car features a ‘VenomAero’ carbon‑fiber performance kit, enhancing the cooling and handling capabilities of the car while imparting signature Hennessey style. <- Gallery -> The new 35th anniversary Super Venom Mustang will only see 35 examples made, and each will feature a “91” hood graphic, in reference to the year when Hennessey was founded. As Hennessey continues to grow, its dedication to American performance excellence will continue to result in incredible custom vehicles and hypercars, including the new ultra-exclusive Super Venom Mustang.

Watch Hennessey Race The Ford Mustang Dark Horse & Shelby...

Two thoroughbred pony cars duke it out. For decades, the pinnacle of Ford Mustang performance was shown through Shelby Mustangs, which have offered increased power, racing-inspired engineering, and dialed-in performance focus. However, with the introduction of the newest generation of the Ford Mustang, Ford has decided to up the ante on the Mustang without the Shelby name, and has introduced the new Ford Mustang Dark Horse. With up to 500 horsepower coming from its 5.0-liter V8 engine, it’s one of the most powerful Ford Mustangs yet, and now that it’s out and on the road, one of the premier specialists in American performance simply had to put it to the test. Of course, that specialist is Hennessey, based in Texas and responsible for some of the most incredible performance upgrades for American cars, as well as some of the world’s most incredible hypercars. To test the mettle of the new Ford Mustang Dark Horse, Hennessey decided to race it against the reigning poster performance Mustang: the Shelby GT350R. Both cars are stock, with the Dark Horse boasting a naturally aspirated 5.0-liter V8 with 500 horsepower paired with a 10-speed automatic transmission, and the Shelby sporting a 526-horsepower 5.2-liter V8, with a six-speed manual instead. The two cars took to Hennessey’s Pennzoil Proving Grounds to see which is faster. In a short drag race with a rolling start, both cars proved that they were quick and highly capable of delivering immense power and reaching high speeds, but due to the increased power of the Shelby, as well as its weight savings by roughly 140 pounds compared to the Dark Horse, it was able to come out on top. Both of these cars are incredibly powerful and quick, and prove that American performance is not to be underestimated, but in this race, the Shelby GT350R was the winner.

Hennessey's Supercharged Mach 1 Mustang Makes 800 Horsepower

In true Hennessey fashion, the Ford Mustang Mach 1 gets supercharged for some serious muscle. Mach 1 is quite the famous name in the Mustang world. Originally meant to replace the GT designation we know many modern Mustangs for today, the Mach 1 name was a way of telling customers that a Mustang took performance seriously. Through the late 60s and 70s, and briefly in 2003 and 2004, the Mach 1 Mustang was an edition that was serious about speed. Now, it’s returned, with all the power, performance, and retro appeal that made the Mustang as desirable of a car as it always has been, and then some. However, as we’ve come to know, Hennessey muscle cars are all about power and performance, which is why they decided to see what the Mach 1 would be capable of with a little help, in the name of a Hennessey supercharger. MUST READ: Custom 2009 Ford Mustang “AV8R” For Sale What happens is that the Mach 1 Mustang ends up with an incredible 800 horsepower, which makes for speed and power that the Mach 1 has never known before. And speaking of the speed of sound, there’s nothing quite like the sound of a supercharged 5.0-liter V8 engine, and the supercharged Mach 1 delivers quite the chorus once it’s opened up, roaring and burbling as you put the foot on the pedal. When it comes to giving your Mustang a serious performance injection, Hennessey provides an effortless one-way ticket. Source: Hennessey

Hennessey HPE850 vs Stock Shelby GT500

In the normal world a new Shelby Mustang GT500 is much faster than the GT350. Normal is not allowed at Hennessey Performance. Intended to appeal to different buyers, the GT 500 arrived from Ford with 760 horsepower and a dual clutch automatic. The GT350 packs America's first production flat-plane crank and a six-speed manual. Although both engines share the same engine block and similar heads, naturally-aspirated model comes into its own above 7,000 RPM. Hennessey Performance C8 Corvette Exhaust Screams on the Dyno To be honest, a stock GT350 or GT350 R doesn't have much power below 5,000 rpm, so you are forced to wind each gear out near 8,000 rpm to reach peak torque. That is why the team at Hennessey Performance decided to add a supercharger. How does one supercharged Mustang compare to another?
