2012 Opel Astra J GTC Dimensions, Size & Specs

The curb weight of the Opel Astra J GTC varies between 1430 kg (3153 lbs) and 1571 kg (3463 lbs) depending on the configuration and options such as engine size and trim. The maximum permissible weight is between 1840 kg (4056 lbs) and 2080 kg (4585 lbs), reflecting the vehicle's ability to carry passengers and cargo safely without compromising performance. These weights influence fuel efficiency, handling, and ride comfort, balancing sporty dynamics with practical usability.

The Opel Astra J GTC offers a practical luggage capacity of 380 liters (13.4 cubic feet) with the rear seats upright, ideal for daily use such as grocery shopping or weekend trips. When the rear seats are folded down, this capacity expands significantly to 1165 liters (41.1 cubic feet), providing ample space for larger items and enhancing the car's versatility for transporting bulky goods or luggage. This well-thought-out design makes the Astra J GTC suitable for a variety of lifestyle needs while maintaining its sporty coupe-hatchback profile.

The Opel Astra J GTC features a ride height or ground clearance of 112 mm (4.4 inches). This relatively low ground clearance enhances the vehicle's aerodynamic profile and improves handling by lowering the center of gravity, which is beneficial for sporty driving and cornering stability. However, this ground clearance requires cautious driving over speed bumps and uneven surfaces to avoid potential undercarriage damage, making it more suited to smooth urban and highway roads rather than off-road conditions.

The Opel Astra J GTC is equipped with a range of rim sizes including 17-inch, 18-inch, and 19-inch wheels, catering to different driving preferences and styles. Correspondingly, the tire sizes available are 235/55 R17, 235/50 R18, and 235/45 R19. These sizes balance aesthetics with performance, providing good grip, ride comfort, and handling precision. The larger 19-inch rims and lower-profile tires are particularly favored for a sportier look and improved road feedback.

Yes, the Opel Astra J GTC fits comfortably into a standard garage. With a length of 4466 mm (175.9 inches), width of 1840 mm (72.4 inches), and height of 1482 mm (58.3 inches), it suits typical residential garage dimensions, which generally accommodate vehicles up to around 2.5 meters (98 inches) in width including mirrors and about 5 meters (197 inches) in length easily. However, given the mirror width when opened is 2020 mm (79.5 inches), care should be taken to fold mirrors if clearance is tight to avoid damage.

Comparing the Opel Astra J GTC to its predecessor, the Astra H GTC, the newer Astra J generation is slightly larger and more refined in dimension. The Astra J measures 4466 mm in length, which is marginally longer than the Astra H, offering a bit more interior space and luggage capacity. Width has increased as well, providing improved shoulder room for passengers. These dimensional enhancements translate into a roomier cabin, better comfort, and a more modern design language, while still maintaining the sporty essence of the GTC hatchback variants.

While slightly wider than some rivals, it balances sporty design with usable interior dimensions.
