Gordon Murray Automotive (GMA) is pushing its upcoming T.33 supercar to the limits with rigorous cold-weather testing in the Arctic Circle. The prototype testing, captured in recent footage, reveals key details about the T.33’s performance and engineering as it nears customer deliveries. This testing phase ensures the car can withstand extreme conditions, even though most buyers will likely never drive it in snow.
Engineering Philosophy: A Modern McLaren F1
The T.33 builds on the same design principles as the T.50, Gordon Murray’s tribute to the iconic McLaren F1. It features a naturally aspirated 3.9-liter V12 engine developed by Cosworth, tuned to deliver 606 horsepower and 333 lb-ft of torque.
The engine’s output has been slightly reduced compared to the T.50 (654 hp / 344 lb-ft) with a redline of 11,100 rpm. This isn’t about lacking power; the T.33 is designed to be exceptionally lightweight at under 2,420 lbs (1,100 kg), making it competitive with more powerful vehicles.
Winter Testing Highlights: Stability and Aerodynamics
Footage shows three uncamouflaged prototypes operating in tandem with GMA engineers. Despite winter tires, the rear-wheel-drive configuration results in some wheelspin on the snow, highlighting the raw power delivery.
The video also showcases the deployable rear wing for the first time. This is a simple yet effective aerodynamic feature that adjusts based on driving conditions. GMA has equipped the car with carbon-ceramic brakes from Brembo and a lightweight carbon fiber monocoque chassis with double wishbone suspension.
Unlike the T.50, which eschewed power steering, the T.33 will include hydraulically-assisted steering for better control.
Production and Future Variants
Production will be limited to 100 Coupe units, with another 100 Spider variants. The T.33 has been homologated for sale in the US. GMA is also developing a more track-focused T.33 S variant for enthusiasts seeking even higher performance.
The T.33’s commitment to lightweight construction and naturally aspirated power represents a refreshing approach in a market increasingly dominated by hybrids and electric vehicles. This focus ensures a driving experience that is both raw and refined.
The T.33 is designed to deliver a high-performance driving experience that emphasizes driver engagement and analog feel. It’s a testament to Gordon Murray’s dedication to automotive purity.
