Hennessey Performance Engineering is an American tuning house specializing in modifying sports and super cars from several brands like Ferrari, Porsche, McLaren, Chevrolet, Dodge, Audi, Mercedes-Benz, Toyota, Nissan, Mustang, Cadillac, Lotus, Jeep, Ford, BMW, Bentley, Chrysler, GMC, Lincoln and Lexus. Established in 1991 by John Hennessey, their main facility is located west of Houston, Texas. The firm focuses on mechanical component modification for creating high-powered cars. Besides performance automobiles, they also tune sport utility vehicles such as Ford Raptors and Jeep Cherokees. They also work on luxury cars like Bentley's and muscle cars like Dodge Charger and Challenger. Their new art of performance is portrayed on the Dodge Charger Hellcat, which is a sedan and is claimed to the be the world's fastest car in the sedan genre.
With 707hp on a tap, appreciation must be given to its supercharged 6.2 litre V8 engine, the Dodge Charger SRT Hellcat is the world's fastest sedan as its top speed approaches nearly touching a wind breaking 330Km. In typical Hennessey Performance fashion however, no standard horsepower figure is enough, so the American tuner offers its very own HPE800 upgrade package. The upgrades are also available with the Challenger SRT Hellcat, which uses the same engine. As it is the Charger Hellcat is quieter and less taxing to drive than the Challenger, smoothing over road irregularities, rather than reporting each on through the steering wheel and seat. Though the Challenger is still a true thug of the range, the Charger atleast looks like it deserves to be part of the gang. Both the cars that undergo the upgrade which is the HPE800 and HPE850 receive some additional badging , inside the team has just have a numbered plaque on the dash and embroided Hennessy headrests.
Whatever the exact amount is, the extra grunt was sourced by way of a new electronic control module, an in house tune, a high flow air filter, a port-matched throttle body and a new supercharger pulley to increase boost. The suped-up Charger was already the world's most powerful production sedan, now that Hennessey's improvements are added on, it will push the car and physics to break the limits. Although its top speed won't we seen having a difference, the power that you feel would be completely different than your past driving experince in a Dodge Charger Hellcat. There's no modifications conceived in the interior, its just the under the hood stuff, which gives life to the car. This whole project on getting this already fast vehicle a slight upgrade in power, shows that some people felt that 707hp isn't enough to feel power and needed more to keep the needle escalating upwards.
Tuning vehicles has been a status symbol for most motor enthusiasts, but it takes someone who is passionate on tuning to hand over his keys to a professional, trustable tuner. As with great power, comes great responsibility, while driving at top speeds, the driver must know the road and should not create harm to other co-drivers on the road.
