2017 Vauxhall Insignia II Grand Sport Dimensions, Size & Specs

The Vauxhall Insignia II Grand Sport has a curb weight ranging between 1441 kg to 1649 kg (3176 to 3634 lbs), depending on the variant and equipment levels. The maximum permissible weight (gross vehicle weight rating) is between 2015 kg and 2340 kg (4442 to 5157 lbs). This weight range reflects its robust build quality and diverse trim options, ensuring a balance between performance, fuel efficiency, and safety.

The Vauxhall Insignia II Grand Sport offers a generous luggage capacity of 490 liters (17.3 cubic feet) with the rear seats in use. When the rear seats are folded down, this capacity expands significantly to 1450 liters (51.2 cubic feet). This flexibility makes the Insignia Grand Sport suitable both for everyday commuting with ample trunk space and for transporting larger cargo or luggage on longer trips.

The Vauxhall Insignia II Grand Sport's dimensions are 4897 mm (192.7 inches) in length and 1863 mm (73.3 inches) in width, excluding mirrors. Standard UK and European garages generally measure around 2400 mm (94.5 inches) wide and 4800 mm (189 inches) deep. Given the Insignia’s length slightly exceeds typical garage depth, and its width is close to common garage widths (especially when mirrors are open at 2093 mm/82.4 inches), parking the vehicle inside a standard garage requires careful maneuvering. However, many garages designed for midsize vehicles will accommodate it, provided mirrors are folded to reduce width and drivers approach parking with precision.

Compared to the Vauxhall Insignia I, the Insignia II Grand Sport introduced in 2017 is larger and sleeker. The previous generation was slightly shorter; while exact figures vary by model, the 2017 Insignia II’s 4897 mm (192.7 in) length marks an increase, offering more cabin and cargo space. In width, the Grand Sport also expanded, now measuring 1863 mm (73.3 in) compared to the predecessor’s narrower stance. The newer generation's lower height of 1455 mm (57.3 in) improves aerodynamics for a sportier profile. Overall, the second generation delivers more interior room, cargo capacity, and a modern design while maintaining a sporty hatchback silhouette.

The Vauxhall Insignia II Grand Sport comes with several rim and tire size options including 17, 18, and 20-inch rims. Tire sizes available are 215/55 R17, 225/55 R17, 245/55 R18, 245/45 R18, and 245/35 R20. Larger rims (20-inch) and wider tires like 245/35 R20 improve grip and handling, offering sportier driving characteristics but may slightly compromise ride comfort and fuel efficiency. Smaller rims (17-inch) paired with narrower tires provide a smoother ride and better fuel economy, ideal for daily driving and long-distance comfort. This range allows buyers to choose between sportiness and practicality.

The roof load capacity of the Vauxhall Insignia II Grand Sport is rated at 100 kg (220 lbs). This means the vehicle can safely support roof racks, cargo boxes, or bike carriers up to this weight limit. When transporting items on the roof, it's important not to exceed this limit to maintain vehicle stability, handling, and safety during driving.

In comparison with similar midsize hatchbacks such as the Ford Mondeo Hatchback, Volkswagen Passat Variant, or Mazda 6 Hatchback, the Vauxhall Insignia II Grand Sport is competitive in size. Its length of 4897 mm (192.7 in) and width of 1863 mm (73.3 in) make it one of the larger vehicles in its segment, providing more interior space and cargo capacity. While the Passat and Mondeo also offer spacious cabins, the Insignia's sportier Grand Sport design gives it a distinctive, sleek coupe-like roofline. This balance of size and design makes the Insignia attractive for buyers seeking practicality without sacrificing style.

The curb weight of the Vauxhall Insignia II Grand Sport ranges from about 1441 kg (3176 lbs) to 1649 kg (3634 lbs), depending largely on equipment levels, engine options, and trim variants. Lighter models typically feature smaller engines and fewer luxury options, while higher-spec versions with advanced safety features, AWD systems, and more amenities weigh toward the upper end of this range. Understanding these weight variations helps determine fuel efficiency, handling dynamics, and driving comfort.

The Vauxhall Insignia II Grand Sport (2017-2020) features a modern design with a sleek, aerodynamic profile that balances sporty looks with premium functionality. Key highlights include advanced driver assistance systems, a spacious cabin with comfortable seating, and a flexible luggage area expanding from 490 to 1450 liters.

With options for 17 to 20-inch alloy wheels and various tech features, the Insignia Grand Sport appeals to drivers looking for a stylish and practical midsize hatchback.
