These are angled at 71 degrees when deployed, which happens automatically at 71 mph.The carbon-fiber Blackbird predominantly references its aeronautical namesake through its exterior styling, most notably the distinctive chine line that runs along the flanks of the car.The decidedly analog interior eschews display screens and is anchored by the dominant tachometer and gated gearshift.The cockpit features room for two custom-made duffel bags behind the seats, and a place to hang your hat.AdvertisementAdvertisementAccording to Hennessy's design director, "there is a very sculptural kind of roof intake that's attached directly to the engine."The Blackbird wears Michelin Pilot Sport Cup 2 tires.On August 14, a show prototype will be introduced in Northern California's Carmel Valley as part of the Quail, a Motorsports Gathering.Only 71 examples of the Hennessey Blackbird will be made, each with a starting price of $2.5 million.
