Vehicle That Navigates Inverted on Rooftops, Marking a Global First

Upside-down propulsion has moved from theory to reality: The McMurtry Sp, a British electric car, has demonstrated the capability for vehicles to drive in an inverted position, even from a stationary state.

Vehicle That Navigates Inverted on Rooftops, Marking a Global First

The McMurtry Spéirling, an electric hypercar, has made headlines in the automotive world with its extraordinary ability to drive upside down. This feat was achieved through a fan system that creates an underpressure under the car's floor, stronger than gravity, allowing it to generate enough force to counteract gravity and stick to the surface even when inverted.

The demonstration of this groundbreaking vehicle took place at McMurtry Automotive's headquarters in southwest England, causing quite a stir among experts. The McMurtry Spéirling, designed by a small team of creative engineers led by Thomas Yates, accelerates from 0 to 96 km/h (60 mph) in a mere 1.5 seconds and corners at over three times its own weight (over 3g).

The McMurtry Spéirling's power comes from a substantial electric output of 1250 horsepower, with an optional upgrade to 1350 horsepower. It runs on an 800-volt electric system, which not only powers the car but also regenerates energy through kinetic energy recovery during braking and deceleration, enhancing efficiency and performance.

The Spéirling's aerodynamic design provides unparalleled downforce, capable of upside-down driving at speed. This is a significant safety feature, as it keeps the vehicle securely planted during extreme maneuvers. The car's innovative ability to stay adhered to the track even when upside down depends heavily on both mechanical grip and aerodynamic stability.

The McMurtry Spéirling prototype used for the demonstration is named Speirling PURE VP1. This model is a further development of the one that set the Goodwood record and is scheduled for production from 2026. The planned production run for the McMurtry Speirling PURE VP1 is 100 vehicles.

On the same day of the demonstration, the McMurtry Speirling broke the track record on the famous Top Gear test track by 3.1 seconds. The previous record was set in 2004 by a Renault R24 with a V10 engine - a Formula 1 car. The McMurtry Speirling PURE VP1 meets the safety standards of the LMP1 class, ensuring a safe and thrilling driving experience for its future owners.

McMurtry Automotive was founded in 2016 by engineer and entrepreneur Sir David McMurtry, with a mission to combine extreme driving pleasure with simple technology. The company's innovative approach to electric vehicle design and performance has set a new standard in the automotive industry, and the McMurtry Spéirling is a testament to their relentless pursuit of excellence.
