The Opel Astra J (fourth generation) marks a major stylistic and qualitative turning point for the brand with the lightning bolt logo. Based on the GM Delta II platform (shared with the Chevrolet Cruze), it stands out for its excellent soundproofing, high-level ride comfort, and technological equipment rare for its time (AFL+ adaptive headlights, AGR ergonomic seats, FlexRide adaptive suspension). However, this design comes with a major drawback: significant excess weight (often over 1,400 kg unladen), which penalizes performance, increases fuel consumption for gasoline engines, and prematurely stresses the running gear and braking system. The late 2012 facelift brought minor aesthetic changes, new engine blocks (including the excellent 1.6 SIDI gasoline and 1.6 CDTI diesel), and, most imp
The Opel Astra J is a 'road-trip' compact: heavy, comfortable, quiet, and designed for long journeys. In gasoline versions, it suffers from its weight, which makes the naturally aspirated engines (1.4 and 1.6) anemic and thirsty. The 1.4 Turbo 140 hp is the most rational choice, offering good driving pleasure, provided the condition of the manual gearbox (M32) is scrupulously checked if the model is prior to 2013. Facelifted versions (post-2013) equipped with the 1.6 SIDI are excellent used car deals, often undervalued. It's a vehicle to NEGOTIATE due to the transmission risk, but it offers a very attractive price/performance/comfort ratio on the used car market.
