The Holden Astra AH, marketed as the Opel Astra H in Europe, is a compact car that marked a significant shift in the model's design and engineering. Introduced in 2004, the Astra H represented the fourth generation of the popular Astra nameplate and underwent a significant facelift in 2007. It was produced until 2009, when it was replaced by the J-segment Astra J. This model showcased a more dynamic and modern design language, featuring sharper lines, a more prominent grille, and a more sloping roofline. The Astra H also boasted a spacious interior, offering comfortable seating for five occupants and a relatively generous cargo capacity.

The Holden Astra AH/Opel Astra H offered a variety of engine options, ranging from economical petrol and diesel units to more powerful turbocharged versions. These engines were paired with a selection of manual and automatic transmissions, providing a range of driving experiences to suit different needs. The vehicle's suspension system was designed for a comfortable ride, while also offering a level of handling agility that was appreciated by drivers. Notably, the Astra H introduced the innovative "FlexRide" system, allowing drivers to adjust the suspension settings to suit their preferences and driving conditions. This system offered a choice of three modes – "Tour," "Sport," and "Standard" – catering to comfort, sporty handling, or a balance of the two.
