Hennessy Special Vehicles is unveiling its much-awaited Venom F5 hypercar today at the SEMA Show, and the beast dubbed "America's Hypercar" is making big promises. Hennessey teased the stunner a couple weeks ago, saying its intent was to take on the Bugatti Chiron for the title of world's fastest car.

Now we have more details to go on for the F5. Its twin-turbo, 7.4-liter aluminum V8 produces an astounding 1,600 horsepower and 1,300 pound-feet of torque, giving it a top speed of 301 miles per hour. Acceleration will be quick: from 0 to 186 mph in less than 10 seconds and 0 to 249 and back to rest in less than 30 seconds, though independent performance tests of course will have to bear out those claims. The engine is mated to a seven-speed single-clutch paddle-shift transmission that drives the rear wheels. Unlike the car it replaces, the Venom GT, which was built atop a Lotus Elise platform, the Venom F5 gets an all-new, lightweight chassis and carbon-fiber body, giving it a curb weight of just 2,950 pounds.

"We've designed F5 to be timeless so that in 25 years it will still have a level of performance and design that will be unmatched," CEO John Hennessey said in a statement. "The F5 is an all new car, designed and built from the ground up, from the engine to the chassis. We expect the Venom F5, named for the most powerful tornado speed winds on the Fujita scale, to be the first road car capable of achieving more than 300 mph and have worked closely with Pennzoil to get us across the finish line."

The Venom GT, which had a 1,451-horsepower twin-turbo 7.0-liter V8, was unofficially dubbed the world's fastest car in 2014, having hit 270.49 mph, though Bugatti plans to challenge that next year in the Chiron.

Base price will be a cool $1.6 million, with just 24 units to be built. And according to "Top Gear," John Hennessey himself will hand-pick its recipients, with first deliveries starting in 2019.

The F5 makes 1,817 horsepower at a screaming 8,000 rpm and 1,193 pound-feet of torque at 5,500 rpm. It also apparently will make at least 1,000 pound-feet of torque from 2,000 to 8,000 rpm. Redline is 8,200 rpm. It's worth noting that these numbers put the Venom over 200 horsepower ahead of the Bugatti Chiron Super Sport 300+, Koenigsegg Jesko, and Hennessey's original power goal. The engine revs 1,000 rpm higher than the original prototype, too. This is all good news considering Hennessey wants to break the 300 mph barrier like Bugatti has and Koenigsegg aims to do.

The engine itself has changed since we last saw it. When it was shown at The Quail last year, it was all-aluminum and had a displacement of 7.6 liters. Displacement has dropped down to 6.6 liters, and the engine block changed from aluminum to forged steel. But as with the prototype, it's twin-turbocharged, uses pushrods instead of overhead cams, and the heads, intake manifold and pistons are all still aluminum. The engine has a name, now, too: Fury.

Hennessey also announced it will begin testing the whole car later this year. The company will build 24 examples total, each with a price of about $1.6 million.

Just over six years since the project was announced and a rendering released, Hennessey Performance has finally shown the running, production version of its new supercar, the Hennessey Venom F5. It still looks similar to the original rendering and concept. The production model gives us our first real look at the car's interior, too.

The basic shape of the Venom F5 stays fairly true to the original concept. The carbon fiber monocoque is very curvy with a low nose, huge vents, and slightly narrow cabin. But there are subtle changes throughout. Creases have been softened everywhere on the car. The big fixed wing is gone. The carbon fiber engine cover has smaller vents. Quad tailpipes stick out the back instead of the triple pipes arranged in a triangle found on the concept. They're all changes we think are improvements, and make the car look more mature and serious, especially in the moody dark blue of this example.

Looking at the interior, the dominating feature is the wild steering wheel that looks like a cross between a Formula One wheel and an airplane yoke. All of the car's main controls such as turn signals, wipers and lights are on the wheel's face. The rest of the interior is reminiscent of other high-performance supercars. Most every surface is bare carbon fiber, except for some leather coverings on the dash and on the seat pads, as well as aluminum plates in the grab handles with the American and Texas flags. Screens make up the instrument cluster and infotainment.

The car's specifications haven't changed since the reveal of the final engine. It's a twin-turbocharged 6.6-liter V8 making 1,817 horsepower and 1,193 pound-feet of torque. The car weighs in at 2,998 pounds. Hennessey claims a 0-62 mph time of less than 3 seconds and a 0-124 mph time of less than 5 seconds. Famed GM engineer John Heinricy also signed on with Hennessey to help fine tune the car's driving dynamics, too.

Hennessey is also still aiming for a top speed of more than 311 mph with the Venom F5. The company is slated to do a run next year at the NASA space shuttle landing strip. And in a clear effort to avoid the same controversy that has surrounded the SSC Tuatara, Hennessey has stated that Racelogic engineers will be on hand to install the VBOX data recorders and to verify data collected. Unedited video and GPS data will be shared publicly following the run, and witnesses will be at the event.

Hennessey will build 24 examples of the Venom F5 coupe. The company has previously stated that 12 will be sold in the United States and the other 12 will go to overseas buyers. Each one has a starting price of $2.1 million. Deliveries are set to begin next year in time for Hennessey Performance's 30th anniversary. Once the coupes are built and sold, Hennessey will likely begin production of the Venom F5 roadster announced last year.
