The Opel Astra J is a compact car produced by German automaker Opel from 2009 to 2015. It was the fifth generation of the Astra range and represented a significant departure from its predecessor, the Astra H. The Astra J featured a completely new platform, codenamed GM Delta II, which was shared with other General Motors vehicles such as the Chevrolet Cruze and Buick Verano. This platform offered improved handling, fuel efficiency, and interior space compared to the previous generation. The Astra J was available in a wide variety of body styles, including a five-door hatchback, a three-door hatchback, a four-door sedan, and a five-door station wagon. It was also offered with a range of petrol and diesel engines, including a 1.4-liter turbocharged petrol engine, a 1.6-liter turbocharged petrol engine, and a 1.7-liter diesel engine. The Opel Astra J's design was a bold departure from the previous generation, with a more angular and modern look. The interior featured a more driver-oriented cockpit, with a high-mounted center console and a prominent instrument cluster. The Astra J was equipped with numerous features, including electronic stability control, anti-lock brakes, and multiple airbags. It was also available with optional features such as a panoramic sunroof, a navigation system, and a rearview camera. The Astra J received positive reviews for its handling, fuel efficiency, and interior space. It was also praised for its value for money, with a competitive price point compared to its rivals. However, some critics noted that the interior materials could be perceived as being somewhat cheap and that the ride quality could be somewhat firm.
