Hennessey has brought back its Christmas Tree Run tradition, and in 2025 the attempt edged close to the symbolic 320 km/h mark. The festive run with a decorated tree on the roof was set by the new Chevrolet Corvette ZR1: according to 32CARS.RU, the supercar was pushed to roughly 315 km/h on a runway.

The premise sounds absurd—and that’s exactly why it works. You take a production car with extreme performance, strap a lit tree to the roof, and probe the limits in a setting where aerodynamics suddenly becomes the main opponent. The spectacle may be playful, but it neatly shows how ruthless air resistance gets at high speed.

The choice of the ZR1 is logical. In its 2026 specification it’s a Corvette with a 5.5-liter flat-plane V8, two turbochargers, a claimed 1,064 hp, and an eight-speed transmission. The run used a version with the ZTK package and a large rear wing: it adds downforce but also drag, and above that sat a 1.5-meter tree acting like a brick in the airstream. At these speeds every small detail turns into a brake, which is why the outcome feels particularly impressive.

The team also mentioned a control pass without the tree: the ZR1 reached 330 km/h before the driver had to lift due to the runway’s limited length.
