Notable cars
Hennessey Venom 650R
The Hennessey Venom 650R is one of the first offerings provided from the tuning company. Available as a package to the 1996 Dodge Viper GTS, the Venom 650R was one of the fastest road legal cars in the world. Upgrades included a US$37,000 engine upgrade that utilised enlarged cylinder bores, and longer stroke to increase displacement from the stock 488 cu in (8.0 L) to 514 cu in (8.4 L) along with forged steel connecting rods (titanium rods were an extra $3500) and forged aluminum pistons; the whole assembly was then balanced and blueprinted to bring the total power output to 650 hp (659 PS; 485 kW) at 5,800 rpm and 650 lb?ft (881 N?m) of torque at 4,500 rpm bumping the compression ratio up to 10.5:1. On the intake side, a competition airbox feeds 70-millimeter billet throttle bodies and a port-matched intake manifold. On the exhaust side, a set of tuned-length stainless steel headers sent spent gases back to a 3.0-inch stainless exhaust system that retained the stock catalytic converters, but allowed them to be easily bypassed for track day performance. New engine management software bumped the idle up to a smoother 1,000 rpm, disabled the 1-4 skip-shift transmission feature, turned the cooling fans on sooner, and packed recalibrated fuel and ignition curves. Completing the package was the VenomAero carbon fiber body upgrade that cut weight, added functional brake cooling ducts along with a rear wing and optimized downforce. All of these modifications allowed the car to accelerate from 0-60 mph (0-97 km/h) in 3.3 seconds, complete the 1/4-mile in 10.8 seconds at a speed of 130.1 mph (209 km/h) and propel the car to a top speed of over 215 mph (346 km/h). A Brembo race spec braking system and a Penske adjustable suspension system with 30 variable damping settings were available as an option. The total cost of the package stood at US$108,500 excluding the price of a stock Viper GTS.
Hennessey Venom GT
In 2010, Hennessey Performance revealed the Hennessey Venom GT. The Venom GT is based on the Lotus Exige and has a twin-turbocharged V8 engine that generates 1,244 hp. The car weighs 1,244 kg and has a top speed of 270.49 mph. Three "World's Fastest Edition" Venom GT coupés were produced in 2014 to commemorate the car's 270.49 mph (435 km/h) record run.
A roadster variant dubbed the Venom GT Spyder was launched in 2012 on the request Aerosmith lead singer Steven Tyler. It is based off the Lotus Elise and adds 30 lb (14 kg) to the curb weight due to structural changes. The production of the Spyder was limited to five units with a one-off Spyder being produced as the "Final edition" model bringing the total to 6 units. The final edition gained a total of 204 hp (207 PS; 152 kW) and was 9 lb (4 kg) lighter than the regular Spyder.
Hennessey Venom F5
The Venom GT's successor, the Hennessey Venom F5 was unveiled at the SEMA Show in Las Vegas, Nevada, on November 1, 2017, with high expectations of its intended world-beating speed record. Using its projected 2.0 second 0-60 mph (0-97 km/h) acceleration and 301 mph (484 km/h) top speed, Hennessey's Venom F5 aims to eliminate the Bugatti Chiron and the Koenigsegg Agera on all acceleration and speed factors. The Venom F5 contains a bespoke proprietary 7.4-liter twin-turbocharged V8, making this the company's first in-house engine. It produces 1,600 hp (1,193 kW; 1,622 PS) and 1,300 lb?ft (1,763 N?m) of torque. Pennzoil and Shell are partners with Hennessey for the project to help reach the 300 mph (483 km/h) top speed mark. The top speed is claimed to be 301 mph (484 km/h) through a V-MAX speed-tracking system. Hennessey predicts the car can accelerate from 0-186 mph (0-300 km/h) in a time of under 10 seconds and 0-249 mph (0-400 km/h) time of under 20 seconds. Only 24 will be built with each car costing US$1.6 million.
