2005 Opel Astra H GTC Dimensions, Size & Specs

When the side mirrors of the Opel Astra H GTC are opened, the width increases to 2033 mm (80 inches). This measurement is crucial for understanding the car's full spatial footprint, especially for parking in standard garages or maneuvering through tight spaces where mirror clearance must be considered.

The Opel Astra H GTC has a curb weight ranging from 1110 to 1305 kg (2447 to 2877 lbs) and a maximum weight between 1685 and 1880 kg (3716 to 4145 lbs). This relatively light curb weight contributes to agile handling and fuel efficiency, while the maximum weight indicates the vehicle's gross vehicle weight including passengers and cargo, influencing suspension and braking performance.

The Astra H GTC offers a luggage capacity of 340 to 380 liters (12 to 13.4 cubic feet) with the rear seats upright, making it practical for everyday use such as groceries or medium-sized luggage. When the rear seats are folded down, the capacity expands to 1070 liters (approximately 37.8 cubic feet), allowing for significantly larger cargo transport and enhancing the vehicle's versatility for carrying bulky items.

The ride height of the Opel Astra H GTC ranges from 119 to 140 mm (4.7 to 5.5 inches). This clearance is typical for compact hatchbacks, offering a good balance between sporty road handling and practicality. However, it means the car may be less suitable for rough terrain or deep speed bumps compared to vehicles with higher ground clearance.

A standard garage door is usually around 2400 mm (94.5 inches) wide, so with the Opel Astra H GTC’s width of 2033 mm (80 inches) including mirrors, it should comfortably fit into most standard garages. This width allows enough clearance on either side to open doors and park without difficulty, making it practical for residential use.

The Opel Astra H GTC supports rim sizes of 6.5J x 16, 7.5J x 17, and 18 inches, paired with tire sizes 205/55 R16, 225/45 R17, and 225/40 R18 respectively. Larger rims and lower-profile tires provide sportier handling and a more aggressive aesthetic but may reduce ride comfort slightly, whereas smaller wheels emphasize comfort and better absorption of road imperfections.

Compared to its predecessor, the Opel Astra GTC (early 2000s versions), the Astra H GTC is slightly longer and wider, offering improved interior space and a sportier stance. The length of 4290 mm represents a modest increase providing more cabin and luggage capacity, while the widened track and a lower height improve aerodynamics and handling.

The Opel Astra H GTC fits well within the compact hatchback category, with length and width dimensions comparable to rivals like the VW Golf Mk5 and Ford Focus of the mid-2000s. Its length of 4290 mm and width of 1753 mm provide a competitive interior space and road presence, while its relatively low height enhances sporty styling typical in this vehicle segment.

The Opel Astra H GTC is a compact hatchback produced by Opel from 2005 to 2006. Known for its sporty design and practicality, it was offered as part of the broader Astra H generation, specifically designed to provide a sleek three-door option with a focus on dynamic styling and engaging driving characteristics.
