Smart Forfour (W454) 1.5i Brabus (177 Hp)

The Smart Forfour (W454) 1.5i Brabus is a high-performance variant of the first-generation Forfour, a subcompact hatchback produced by Smart from 2005 to 2006. Unlike the standard Forfour, which aimed for fuel efficiency and urban practicality, the Brabus model focused on delivering a more engaging driving experience with increased power and sporty styling. While Smart vehicles were never officially sold in the United States during this period, the Forfour was a significant model in the European city car market, offering a unique blend of compact dimensions, four-seater capability, and surprisingly potent performance in Brabus guise.

Smart Forfour (W454) 1.5i Brabus: An Overview

The W454 Forfour represented Smart’s attempt to expand its lineup beyond the iconic Fortwo. Developed in collaboration with Mitsubishi Motors, the Forfour shared its platform with the Mitsubishi Colt. The 1.5i Brabus version, tuned by the renowned German performance house Brabus, was the range-topping model, offering a substantial power upgrade over the standard engines. It catered to buyers seeking a fun-to-drive, yet practical, city car with a distinctive image. The Forfour, despite its short production run, remains a notable example of early 21st-century microcar design and engineering.

Engine & Performance

The heart of the Forfour 1.5i Brabus is a 1.5-liter inline-four cylinder engine, designated M 122.950, which produces 177 horsepower at 6000 rpm and 230 Nm (169.64 lb.-ft.) of torque at 3500 rpm. This output translates to a power-to-weight ratio of 5.5 kg/Hp and a torque-to-weight ratio of 4.2 kg/Nm. The engine is equipped with a turbocharger and intercooler, significantly boosting its performance. Power is delivered to the front wheels via a five-speed manual transmission. This combination allows the Forfour Brabus to accelerate from 0 to 60 mph in approximately 6.6 seconds and reach a top speed of 221 km/h (137.32 mph). The engine’s specific output of 120.6 hp per liter highlights its impressive engineering. Fuel economy is rated at 8.9 l/100 km (26.4 US mpg) in urban conditions, 5.6 l/100 km (42 US mpg) on the extra-urban cycle, and 6.8 l/100 km (34.6 US mpg) combined.

Design & Features

The Forfour is a five-door hatchback with seating for four adults. Its compact dimensions – 3752 mm (147.72 in.) in length and 1684 mm (66.3 in.) in width – make it ideally suited for navigating congested city streets. The Brabus version featured subtle but effective styling enhancements, including a more aggressive front bumper, side skirts, and a rear spoiler. Inside, the Forfour offered a surprisingly spacious cabin for its size, with a versatile interior layout. The trunk space ranges from 268 liters (9.46 cu. ft.) with the rear seats up to 910 liters (32.14 cu. ft.) with the seats folded down. Safety features included ABS (Anti-lock Braking System) as standard, reflecting the growing importance of safety in the early 2000s. The vehicle’s kerb weight of 965 kg (2127.46 lbs.) contributes to its nimble handling and responsive acceleration.
