The Smart Forfour (W454) 1.3i, producing 95 horsepower, represents a unique chapter in the history of the Smart marque. Introduced in 2004 and produced until 2006, this model was a significant departure for Smart, being the first four-door, four-seater vehicle offered by the brand. While Smart is widely recognized in North America for the diminutive Fortwo, the Forfour was primarily aimed at the European market, offering a more practical and family-oriented option within the microcar segment. It was designed to compete with vehicles like the Fiat Panda and Renault Twingo, providing an alternative for urban drivers seeking a compact and efficient vehicle.
Smart Forfour (W454) 1.3i: A Detailed Overview
The W454 Forfour was the result of a collaboration between Smart and Mitsubishi Motors. It shared its platform with the Mitsubishi Colt, a decision that allowed Smart to expand its model range without incurring the substantial costs of developing an entirely new architecture. This collaboration was a key factor in bringing a larger, more versatile Smart vehicle to market. The Forfour aimed to address criticisms leveled at the Fortwo regarding its limited passenger and cargo capacity, while still maintaining the core Smart values of fuel efficiency and maneuverability.
Engine & Performance
The 1.3i Forfour is powered by a 1.3-liter inline three-cylinder gasoline engine, designated M 135.930. This engine produces 95 horsepower at 6000 rpm and 125 Nm (92.2 lb.-ft.) of torque at 4000 rpm. While not a performance powerhouse, the engine provides adequate power for urban driving and short trips. The power-to-weight ratio of 10.2 kg/Hp (98.4 Hp/tonne) reflects the vehicle’s relatively lightweight construction. Acceleration from 0 to 100 km/h (0-62 mph) takes 10.8 seconds, and 0 to 60 mph is achieved in approximately 10.3 seconds. The Forfour has a maximum speed of 180 km/h (111.85 mph). Fuel economy is a strong point, with combined cycle consumption rated at 5.8 l/100 km (40.6 US mpg, 48.7 UK mpg, 17.2 km/l). The engine utilizes a multi-port manifold fuel injection system and an overhead camshaft (OHC) valvetrain.
Design & Features
The Smart Forfour (W454) is a five-door hatchback, offering seating for four adults. Its compact dimensions – 3752 mm (147.72 in.) in length and 1684 mm (66.3 in.) in width – make it exceptionally maneuverable in congested city environments. The design, while functional, is relatively understated compared to the more distinctive styling of the Fortwo. The interior prioritizes practicality, with a focus on maximizing space within the vehicle’s small footprint. Trunk space ranges from 268 liters (9.46 cu. ft.) with the rear seats up to 910 liters (32.14 cu. ft.) with the rear seats folded down. Safety features for the time included ABS (Anti-lock Braking System) and front and rear disc brakes. The Forfour’s design was a compromise between maximizing interior space and maintaining the Smart brand’s focus on compact city cars. The vehicle’s kerb weight is 965 kg (2127.46 lbs), with a maximum permissible weight of 1450 kg (3196.7 lbs).
