Want to drive upside down? The £1.2m production-ready McMurtry Spéirling is here

The McMurtry Spéirling, a record-chasing speed machine designed to drive upside down, has moved into final production for “public” access, with a price around £1.2 million. The article ties its development to milestones including a 2022 hillclimb record at Goodwood by a prototype, and further testing at the Top Gear test track in 2025 that reportedly dislodged an old Renault F1 car before it later drove upside down. For production, the battery expands to 100kWh from 60kWh in prototypes, and the car adds a modular “McMurtry battery” design with upgrades, up to 200kW of brake-energy recovery, new motors, and improved cooling. Aerodynamic and chassis changes include a swan-neck rear wing, a carbon-fibre monocoque, a downforce-on-demand system with new fans and an onboard compressor, and a 20% higher ride height. Performance figures cited include 0–60 mph in 1.55 seconds, 3g, 190 mph, and 25–31 miles at LMP2 pace, with recharge in about 20 minutes.
