2019 McLaren Senna Dimensions, Size & Specs

The McLaren Senna has an impressively low curb weight of 1198 kg (2,640 lbs). This lightweight design is a result of extensive use of carbon fiber and lightweight materials throughout the chassis and body. The lower weight translates to quicker acceleration, more agile handling, and improved braking performance, making the Senna one of the most track-focused hypercars with exceptional dynamic capabilities.

The McLaren Senna rides on front rims sized 8J x 19 with tires 245/35 R19, and rear rims sized 10J x 20 with tires 315/30 R20. These wide tires and staggered rims provide substantial grip, enhancing cornering traction and high-speed stability. The tire profiles also contribute to a direct steering feel and incredible responsiveness, which are crucial for the Senna’s track-focused nature.

The McLaren Senna is a two-seater coupe focusing on maximum driver engagement and weight reduction rather than passenger space. Its confined cabin prioritizes ergonomics and driver visibility. While comfortable for two adults, interior space is minimal compared to regular sports cars, with a focus on sporting performance over luxury or storage.

The Senna’s dimensions—4744 mm long, 2153 mm wide, and 1195 mm tall—mean it will fit into most standard garages lengthwise and height-wise if the garage door clearance meets or exceeds these measurements. However, its width of 2153 mm (84.7 inches or about 7 feet) is wider than many cars, so it's recommended to measure your garage door and tight spaces carefully to ensure a comfortable fit, especially considering side mirrors and opening doors.

The McLaren Senna, although a standalone hypercar model rather than a direct successor to a previous model, is slightly larger and wider than earlier track-focused McLarens like the P1. Compared to models such as the McLaren 720S, the Senna features more extreme aerodynamic elements and a wider stance. Its lighter weight and aggressive focus make it less about luxury supercar dimensions and more about performance optimization.

Among hypercars such as the Ferrari LaFerrari and Porsche 918 Spyder, the Senna is competitive in size but stands out with a wider track and lower height for improved aerodynamics and grip. Its length of 4744 mm places it slightly longer than some competitors, while its curb weight at 1198 kg is notably lighter, reinforcing its unique focus on ultimate track performance compared to some heavier hypercars.

The McLaren Senna's height of just 1195 mm combined with its wide body (2153 mm) results in a low center of gravity and aggressive stance that significantly enhances aerodynamics. Its size and shape allow for massive downforce generation through active and fixed aero elements such as the large rear wing and front splitters. This downforce greatly improves cornering speeds and stability at high speed, which is critical for its track-focused purpose.

The compact height of 1195 mm (47 inches) gives the Senna a sleek, low profile that benefits aerodynamics and handling. However, this low height can limit headroom and ease of ingress and egress for some drivers. The low seating position is typical for supercars and hypercars and contributes to the driver’s close connection to the road but may be less comfortable for everyday use or taller drivers.

The McLaren Senna’s compact dimensions and lightweight design (1198 kg) translate directly into outstanding performance figures. Its size allows for high agility and precision in handling, while the low weight ensures rapid acceleration and effective braking. These factors combine to make the Senna one of the fastest and most responsive track cars in its category, capable of extraordinary lap times and driving excitement.
