Hennessey Blackbird: 6.2L naturally-aspirated V8, six-speed manual, 71 units

The pitch

Hennessey Special Vehicles has revealed the Blackbird, its third ground-up hypercar after the Venom GT and Venom F5. Where the Venom F5 chases a 500 km/h top-speed number with a 1,817 hp twin-turbo V8, the Blackbird is aimed the other way: naturally aspirated, manual gearbox, no hybrid, no turbos, no driver-assist digital layer to negotiate.

It is positioned against the Koenigsegg CC850 and Pagani Utopia in the "modern analog hypercar" segment that has emerged since 2022, and it takes its visual cues from the Lockheed SR-71 Blackbird reconnaissance aircraft.

The powertrain

At the centre is an all-new 6.2-litre naturally-aspirated V8 co-developed with Ilmor Engineering, the British race-engine specialist known for its work in IndyCar, Formula 1, and its association with Chevrolet's LS7-derived programs. Hennessey lists the following as targets rather than final homologated figures:

Power: ~800-850 hp
Redline: more than 9,000 rpm
0-60 mph: 2.5 s (expected)
Top speed: 220 mph (~354 km/h)
Curb weight: less than 3,000 lb (~1,360 kg)

The gearbox is a six-speed gated manual driving the rear wheels. There is no automatic, no dual-clutch, no paddle-shift option. The layout is front-mid engine.

If the 9,000 rpm redline holds through homologation, the Blackbird would take the title of the highest-revving naturally-aspirated V8 ever fitted to a production car.

The design philosophy

Hennessey's press release repeatedly frames the Blackbird against "increasingly complex, digitized, and hybridized modern hypercars." That is the pitch: an analog counter-argument to the SF90, the Revuelto, the Nevera, the Tourbillon. The mechanical hardware does the work; the driver is not managed by software.

The SR-71 reference is present in the exterior silhouette (long nose, narrow fuselage, tapered rear) but Hennessey has not published detailed images at the reveal.

What is confirmed

Three things are firm:

Production: 71 cars, worldwide, matched to the SR-71's tail number.
Price: starting from $2.5 million before taxes.
Deliveries: 2029-2030.

Hennessey states that more than two-thirds of the 71-car allocation has already been assigned to customers ahead of the reveal.

What is still target rather than fact

The powertrain figures, weight target, and 0-60 / top-speed numbers are all engineering goals at the reveal stage. The Ilmor V8 has not yet been shown in a test mule at speed, and homologation for road use in the US and Europe is a 2028-2029 exercise. Expect refinements before the first delivery.

What this changes

The Blackbird is the first Hennessey since the Venom GT to lead with an emotional-driving pitch rather than a headline top-speed number. It puts a Texas builder into the same conversation as Koenigsegg and Pagani for the first time. It also confirms that the "analog hypercar" category, opened by the CC850 in 2022 and reinforced by the Utopia and by Ferrari's rumoured 12Cilindri MM manual, is not going away.

Whether the Ilmor V8 lives up to its 9,000 rpm target will decide how much of that conversation the Blackbird actually enters.
