2020 McLaren Speedtail Dimensions, Size & Specs

The curb weight of the McLaren Speedtail is 1597 kg (3520 lbs). For a hypercar with hybrid technology and a long body, this weight is relatively low, thanks to extensive use of carbon fiber and lightweight materials. The balanced weight allows the Speedtail to achieve exceptional performance metrics, particularly in acceleration and top speed. The low weight also enhances braking and cornering capabilities, making the driving experience more dynamic and responsive.

The McLaren Speedtail is equipped with 21-inch rims at the front and 20-inch rims at the rear. This staggered wheel setup not only complements the car's futuristic and aerodynamic design but also plays a functional role by optimizing grip and handling balance. Larger front wheels improve front-end stability during high-speed driving, while slightly smaller rear wheels help reduce unsprung mass and improve ride quality. The rims are specifically designed to minimize aerodynamic drag while maximizing tire contact with the road.

Given its length of 5137 mm (202.3 inches), width of 2000 mm (78.7 inches), and very low height of 1120 mm (44.1 inches), the McLaren Speedtail is on the larger side for standard garages. Many typical residential garages have door openings around 2.4 meters (94.5 inches) in width and height clearance of approximately 2.1 to 2.4 meters (83 to 94 inches), so the width usually fits but the length might be tight depending on garage size. Its extremely low height is not an issue. Owners should ensure they have a sufficiently long and wide space to comfortably park and access the Speedtail.

Compared to its predecessor, the McLaren P1, the Speedtail is significantly longer and wider. The P1 measures approximately 4588 mm (180.6 inches) in length, making the Speedtail nearly 550 mm (21.7 inches) longer. The Speedtail’s width of 2000 mm (78.7 inches) is also broader than the P1’s 1944 mm (76.5 inches), while the Speedtail is much lower at 1120 mm (44.1 inches) compared to the P1’s 1188 mm (46.8 inches). These size differences underline the Speedtail's focus on high-speed cruising and aerodynamic efficiency compared to the P1’s track-oriented design.

The McLaren Speedtail is typically longer than many of its hypercar competitors such as the Bugatti Chiron, which measures about 4544 mm (179 inches) in length, and the Koenigsegg Agera RS at 4432 mm (174.5 inches). Its width at 2000 mm (78.7 inches) aligns closely with these rivals. The Speedtail’s very low height (1120 mm / 44.1 inches) is among the lowest, giving it a unique and highly aerodynamic silhouette. Overall, it presents as a grand tourer-style hypercar — longer and lower — prioritizing top speed and high-speed stability over compactness.

The McLaren Speedtail is a three-seat coupe featuring a unique seating arrangement with the driver positioned centrally, flanked by two passenger seats on either side and slightly behind the driver. This layout is rare in production cars and emphasizes the Speedtail’s focus on an unparalleled driving experience. The body is a fixed roof coupe designed with extreme aerodynamic efficiency and futuristic styling cues for a streamlined appearance.

The McLaren Speedtail was produced exclusively in the year 2020, with only 106 units made worldwide. It was designed as a limited-run hyper-GT, representing the pinnacle of McLaren’s technology and design philosophy at the time. The limited production adds to its exclusivity and collectability, making it a highly sought-after vehicle for enthusiasts and collectors.

The McLaren Speedtail was primarily designed as a hyper-GT focused on achieving extraordinary top speeds while maintaining exceptional handling and comfort for long-distance high-speed travel. With a top speed of 403 km/h (250 mph), it’s the fastest McLaren ever made, yet it retains a hybrid powertrain and aerodynamic design optimized for stability and driver comfort. The three-seat layout, luxury materials, and advanced control systems also emphasize comfort and exclusivity without compromising performance.

The McLaren Speedtail’s exceptionally low height of 1120 mm (44.1 inches) dramatically reduces air resistance, contributing to its record-breaking top speed capabilities. This low profile lowers the car's center of gravity, enhancing stability and cornering precision at high speeds, which is critical for a hyper-GT. However, the low height can pose challenges in everyday usability, such as reduced ground clearance for speed bumps and potential difficulty for passengers entering and exiting the vehicle.
