The 2012 Chevrolet Express, part of the vehicle's first and only generation (since 1996), is a versatile full-size van with a range of layouts for commercial or passenger use. It offers a variety of engines including a 4.3L V6 (195 hp), a 5.3L V8 (310 hp), and two potent V8s, a 4.8L (285 hp) and a 6.0L (342 hp). A 6.6L Duramax turbo-diesel V8 (260 hp) is also available for those needing extra torque and efficiency. The transmission is a 4, 5, or 6-speed automatic, associated with a rear-wheel-drive configuration. For passenger models, available trims are LS and LT, with options for 8, 12, or 15 seats. Key safety features include stability control and optional side curtain airbags. The Express doesn't offer many high-tech features, favoring practicality and durability over luxury and technology.
