2017 HSV GTSR Dimensions, Size & Specs

With a width of 1899 mm (74.8 inches), the HSV GTSR provides a broad track that enhances road grip and cornering stability. Standing 1468 mm (57.8 inches) tall, it maintains a low center of gravity to reduce body roll during sharp maneuvers. This combination of wide stance and relatively low height ensures sporty handling characteristics, making it highly capable on both city streets and performance driving conditions.

The HSV GTSR features a spacious luggage capacity of 496 liters (approximately 17.5 cubic feet), which is quite generous for a high-performance sedan. This ample trunk space provides practicality for everyday use, enabling owners to carry suitcases, groceries, or sports equipment without compromising on the coupe-like sporty design.

The HSV GTSR rides on 20-inch rims, with a front size of 9.0J x 20 and rear size 10J x 20, paired with wide tires measuring 255/35 R20 at the front and 275/35 R20 at the rear. These large, wide tires improve grip and traction, especially during aggressive acceleration and cornering. The low-profile tire design also enhances responsiveness and steering feedback, although it may result in a firmer ride compared to smaller wheels.

Given its dimensions, the HSV GTSR—at 5044 mm (198.5 inches) long and 1899 mm (74.8 inches) wide—fits comfortably in most standard residential garages, which are typically about 6 meters (20 feet) deep and 3 meters (10 feet) wide. The car's relatively low height of 1468 mm (57.8 inches) poses no clearance issues for common garage doors, making it practical for urban and suburban use regarding parking and storage.

Compared to its predecessor, the HSV GTSR 2017 maintains a similar footprint in length and width but offers modest refinements in overall dimensions to enhance performance and cabin space. The 2017 model continues the tradition of a large sedan but integrates modern design elements that slightly optimize aerodynamics without significantly changing size. Thus, owners can expect a familiar size profile with improved dynamic attributes and interior comfort.

When compared to other high-performance sedans like the Ford Performance Shelby GT350 or the Dodge Charger SRT Hellcat, the HSV GTSR is generally larger in length and width, offering a commanding road presence. It is longer than many sporty sedans yet remains competitive in width to optimize stability. Its luggage capacity and cabin size are also generous, making it one of the more spacious options in the performance sedan segment without sacrificing agility.

While precise curb weight figures vary, the HSV GTSR’s substantial size—especially its broad width and long wheelbase—along with its robust chassis and reinforced suspension components, result in a well-balanced weight distribution. This enhances high-speed stability and cornering grip. The size requires performance-tuned suspension and braking systems to effectively manage its weight and deliver sports car handling dynamics typical of HSV’s engineering ethos.

The exterior dimensions of the HSV GTSR are carefully engineered to balance aggressive styling and aerodynamic efficiency. The length of 5044 mm (198.5 inches) combined with a low height of 1468 mm (57.8 inches) helps reduce drag and improve airflow underneath and around the vehicle. The width of 1899 mm (74.8 inches) ensures stability at high speeds. These factors contribute to better fuel efficiency than expected for a powerful V8 sedan and enhance high-speed stability.

Yes, the HSV GTSR’s generous footprint directly translates to comfortable interior space for passengers. The wide exterior dimension allows for ample shoulder and elbow room in both front and rear seats, while the sedan’s length contributes to generous legroom. Combined with its ergonomic seat design and premium materials, the HSV GTSR delivers a spacious and comfortable cabin experience suitable for both spirited drives and longer journeys.
