Smart Forfour II (W453) 0.9 (90 Hp)

The Smart Forfour II (W453) 0.9 (90 Hp) is a city car produced by Smart, a microcar manufacturer jointly owned by Mercedes-Benz and Geely. Introduced in 2014 and continuing through 2019, the W453 represented a significant departure from its predecessor, the first-generation Forfour. Unlike the original, which was based on a Mitsubishi platform, the W453 Forfour shared its underpinnings with the Renault Twingo V, resulting in a rear-engine, rear-wheel-drive configuration. This generation aimed to address criticisms of the original Forfour’s practicality and driving dynamics, offering a more refined and engaging experience within the compact city car segment. While Smart vehicles were never officially sold in the United States during this period, the Forfour was a popular choice in European markets, particularly for urban commuters seeking a small, fuel-efficient, and maneuverable vehicle.
