2018 Bentley Continental GT III Dimensions, Size & Specs

The Bentley Continental GT III has a curb weight ranging between 2165 kg (4775 lbs) and 2273 kg (5011 lbs), depending on options and equipment. This weight reflects the substantial build quality, luxury materials, and powerful drivetrain components the car employs. The maximum allowable weight is 2725 kg (6007 lbs), accommodating passengers and cargo without impacting safety or performance parameters. Despite its significant mass, the Continental GT III's advanced chassis tuning, adaptive suspension, and powerful engines ensure agile handling and strong acceleration, maintaining the grand tourer's hallmark balance of comfort and sportiness.

Typical single-car residential garages have a width of about 2438 mm (96 inches) and a length of about 5791 mm (228 inches), allowing most vehicles to fit comfortably. The Bentley Continental GT III measures 4850 mm (190.9 inches) long and 1966 mm (77.4 inches) wide with folded mirrors. This means it will fit into most standard garages with ample space on the sides and length. However, when mirrors are extended to 2187 mm (86.1 inches), clearance might be tighter. For garages on the smaller end or those with narrow doorways, careful maneuvering and folding mirrors are advisable to avoid damage and ensure ease of parking.

The Bentley Continental GT III offers a luggage capacity of 358 liters (approximately 12.6 cubic feet), which is respectable for a luxury grand tourer coupe. This space is designed to accommodate weekend bags or golf equipment, emphasizing its role as a capable vehicle for long-distance travel in comfort. Compared to competitors in the luxury coupe segment, this capacity is competitive, although some rivals may offer more cargo space with practical hatchback designs. Nonetheless, the Continental GT III balances luggage volume with its luxurious interior and design, providing sufficient space without excessive bulk.

The Bentley Continental GT III comes with rim size options of 20, 21, and 22 inches, allowing buyers to select between sporty aesthetics and ride comfort. Tire sizes include 265/40 R21 and 305/35 R21, which are wide performance tires designed to provide excellent grip and stability. Larger rims with lower-profile tires tend to improve handling and cornering precision by reducing sidewall flex, but they may slightly reduce ride comfort. Conversely, the 20-inch rims with taller tire profiles offer a more cushioned ride. These options let drivers tailor the driving experience to their preferences, balancing luxury ride quality with dynamic capability.

With its mirrors opened, the Bentley Continental GT III measures 2187 mm (86.1 inches) wide, which is quite broad compared to average vehicles. This width can present challenges when navigating narrow city streets, tight parking spaces, or car parks designed for smaller cars. Drivers should exercise caution when driving in congested areas, and where possible, fold the mirrors to their 1966 mm (77.4 inches) width to facilitate passage through narrower spaces. Despite this, the car’s advanced parking aids such as cameras and sensors can help mitigate the challenges posed by its wide stance in urban environments.

Compared to the Continental GT II, which was produced from 2011 to 2018, the Continental GT III maintains similar overall dimensions but introduces subtle refinements. The GT III measures 4850 mm in length, closely matching the previous generation's length (around 4842 mm). Width has slightly increased due to the adoption of larger mirror housings and design tweaks, with the GT III ranging up to 2187 mm with mirrors opened, slightly wider than the GT II. Height remains similar at approximately 1405 mm, maintaining the coupe’s sleek profile. These incremental dimensional changes contribute to improved aerodynamics, interior space optimization, and a more commanding road presence without drastically altering the car’s familiar grand touring proportions.

The Bentley Continental GT III competes with luxury grand tourers such as the Aston Martin DB11 and Mercedes-AMG S-Class Coupe. Dimensionally, the GT III is similar in length and width but tends to be heavier due to its opulent construction. For instance, the Aston Martin DB11 is about 4719 mm long and 1944 mm wide, slightly smaller and narrower than the Continental GT III. The Mercedes-AMG S-Class Coupe measures approximately 5034 mm long and 1908 mm wide, slightly longer but generally narrower than the Bentley. The Continental's larger width, especially considering mirror span, contributes to a broader, more imposing stance that emphasizes luxury and presence. Interior space and trunk capacity are competitive, with the Continental balancing space, comfort, and performance effectively in its class.

The Bentley Continental GT III introduced in 2018 marked a significant evolution from its predecessors, with a complete redesign emphasizing lightweight construction and advanced technology. It features an all-aluminum chassis which reduces weight and improves agility. The design language incorporates sharper, more modern styling cues while retaining Bentley’s signature grandeur. Inside, the GT III offers a next-generation infotainment system with a rotating display, enhancing luxury and usability. Performance-wise, the chassis, suspension, and braking systems have been refined for improved handling dynamics. These changes collectively elevate the driving experience, blending traditional Bentley luxury with contemporary engineering and design innovation.

The 2018 Bentley Continental GT III saw improvements in fuel efficiency and emissions compared to its predecessors, partly due to the introduction of a more advanced 4.0-liter twin-turbocharged V8 engine alongside the traditional W12 powerplant. The use of lighter materials and a more aerodynamic body design contributes to better fuel economy in real-world driving. However, as a large luxury grand tourer with powerful engines, its consumption remains higher than typical passenger cars. Bentley also started integrating some mild-hybrid technologies and optimized gearboxes to reduce environmental impact. While it may not be classified as highly eco-friendly, compared to earlier Continental models, the GT III makes strides towards improved efficiency without compromising on performance and luxury.
