Hennessey Blackbird revealed with naturally aspirated V8, manual gearbox

Hennessey has unveiled the Blackbird, its latest hypercar inspired by the Lockheed SR-71 Blackbird reconnaissance aircraft. While the Venom F5 was developed with outright speed and power as its priority, the Blackbird instead places greater emphasis on driver engagement through a naturally aspirated V8, rear-wheel-drive layout, a 6-speed manual gearbox and a screen-free cabin. Production will be limited to 71 units, and customer deliveries are scheduled to begin in 2029.

1. Naturally aspirated 6.2-litre V8 revs to over 9,000rpm
2. Targets sub-1,360kg dry weight and 354kph top speed
3. Screen-free cabin with analogue dials and manual gearbox

Hennessey Blackbird: Engine and performance

Powering the Blackbird is an all-new 6.2-litre naturally aspirated V8, developed with Ilmor Engineering, the company known for its work in IndyCar and NASCAR. Hennessey says the engine will produce 811-862hp, rev beyond 9,000rpm and be the world’s most powerful production naturally aspirated V8. Power is sent exclusively to the rear wheels via a 6-speed manual gearbox with an exposed gate and an exposed linkage.

Without turbochargers or hybrid assistance, Hennessey says the V8 has been engineered to deliver immediate throttle response, linear power delivery and a more engaging soundtrack.

Hennessey claims the Blackbird can sprint from a standstill to 97kph in under 3.0 seconds and reach a 354kph top speed. The Blackbird uses a bespoke carbon-fibre monocoque and carbon-fibre bodywork, giving it a targeted dry weight of under 1,360kg, while also featuring adaptive suspension, Michelin Pilot Sport Cup 2 tyres, ABS and traction control. Despite these performance figures, Hennessey says the focus remains on delivering a more involving driving experience and long-distance usability than on outright performance figures.

Hennessey Blackbird: Exterior design

The Blackbird’s styling takes direct inspiration from the SR-71 Blackbird aircraft. The most distinctive elements are the pair of active vertical stabilisers at the rear, which deploy at speeds above 71mph (114kph) and sit at +/-71 degrees to improve stability and downforce. The diamond-shaped quad exhaust is inspired by the Bell X-1, the first aircraft to break the sound barrier, while the sculpted side pods and bodywork are said to be influenced by Formula 1 and aerospace design. The crisp body-side chine line is another defining styling element of the Blackbird, directly inspired by the SR-71.

Beyond its aircraft-inspired styling, the Blackbird has been engineered for high-speed stability and improved usability. Hennessey says improvements such as a larger glasshouse, better visibility and increased luggage capacity over the Venom F5 are intended to make the car more practical for longer journeys.

Hennessey Blackbird: Interior

The Blackbird’s cabin adopts a deliberately analogue layout. Instead of a digital instrument cluster and central touchscreen, it gets traditional analogue dials, an exposed gear linkage, physical switchgear and a traditional, insert-and-twist ignition key. Smartphone connectivity is handled through the “Hennessey holster”, a dedicated phone mount rather than an integrated infotainment system, while the steering wheel is free of buttons.

Hennessey says the cabin offers more space than the Venom F5 and enough luggage capacity for two full-size carry-on bags. The company also claims the Blackbird has been designed to cover over 1,200km comfortably in a single day, underlining its touring-focused brief.

Hennessey Blackbird: Production

Production of the Blackbird will begin in Texas in 2029, and prices start at USD 2.5 million (around Rs 24 crore), before taxes. Just 71 examples will be built, and more than two-thirds of production has already been allocated ahead of its public debut on August 14 at The Quail during Monterey Car Week in California.
