2018 Hennessey Exorcist


Hennessey's 1000 HP Camaro ZL1 becomes the world's fastest muscle car

Úvalde, TX-Move over 2019 Corvette ZR1 wîth your top speed of 213 mph. On February 12, 2018, professional driver and director of the Ford Performance Driving School, Brian Smith, drove THE EXORCIST, a 1,000 horsepower Chevrolet Camaro ZL1 built by Hennessey Performance (HPE) to a top speed of 217 mph. In the process, THE EXORCIST became the world's fastest Gen6 Camaro.

The run was made on the 8.5-mile high-speed oval at the Continental Tire Proving Grounds located in Úvalde, TX. This is the same test track where the Hennessey team ran their HPE750 Supercharged Mustang to over 200 mph wîth Jay Leno's Garage in 2015. During both tests, speeds were validated wîth Racelogic's Video VBox GPS data logging system.

'We wanted to see if THE EXORCIST could exceed the top speed of the new ZR1 Corvette, which is 213 mph. Mission accomplished', said president and company founder, John Hennessey. 'This is just the first high-performance validation test for THE EXORCIST. We also plan to test our car's 0-60 mph and ¼ mile performance at the dragstrip as well as handling and braking on a road course. Stay tuned.'

Not only is THE EXORCIST faster than the ZR1 Corvette, but it's also faster than supercars like the McLaren 720S, Porsche 911 GT2 RS, Ferrari 812 Superfast, Lamborghini Huracan, and many more.

Vital Stats
Engine : 8-cylinder
Power: 1000 hp
Torque: 883 ft-lbs

The team from Hennessey Performance (HPE) increased the factory's supercharged LT4 V8 engine from 650 bhp to 1,000 bhp by the tried and true method of increasing airflow through the engine. The Hennessey-tuned ZL1 Camaro makes its power by upgrading the factory 1.7L supercharger to a new 2.9L supercharger system wîth a larger intercooler system plus CNC ported cylinder heads, camshaft and valvetrain upgrades, 1 7/8 inch long-tube stainless steel headers wîth high-flow catalytic converters, high-flow intake cold air induction system, engine management recalibration and chassis dyno tuning.

Hennessey utilized the factory wheels and tires on THE EXORCIST for this test but they do offer upgraded wheels and tires for the dragstrip and a road race wheel and tire package. The factory 10-speed transmission was also used and the 217 MPH speed was achieved in ninth gear.

To date, HPE has delivered 20 EXORCISTS to clients and the company plans to only build 100 units in total. Each EXORCIST has its own distinctive Hennessey serial number wîth a plaque in the interior and engine bay. THE EXORCIST can be ordered directly from Hennessey or from authorized Hennessey Chevrolet dealers. All EXORCISTS come wîth a three year/36,000 mile warranty.

'THE EXORCIST offers supercar performance while still retaining everything that you would want in a daily driver wîth a backseat and room for golf clubs in the trunk.', added Hennessey. 'It's kind of like having a new ZR1 Corvette wîth room for 4 people – but faster.'
