The Smart Fortwo Coupe (C450) 0.7 i, produced between 1998 and 2006, represents the initial foray into the microcar segment by the then-new Smart automobile brand. A joint venture between Mercedes-Benz and Swatch, Smart aimed to revolutionize urban transportation with a vehicle designed for maximum space efficiency and maneuverability. The Fortwo, as its name suggests, is a two-seater coupe intended primarily for city driving, offering a unique solution to parking and congestion challenges. While not officially sold in the United States during its initial production run, the Fortwo gained significant attention for its innovative design and became a popular city car throughout Europe.
The Smart Fortwo Coupe (C450): A Pioneering Microcar
The C450 generation Fortwo was the first iteration of the model, establishing the core principles that would define the Smart brand for years to come. It was conceived as a response to growing urban density and the need for a vehicle that could navigate tight spaces with ease. The Fortwo’s diminutive size, coupled with its relatively efficient engine, made it an attractive option for commuters and city dwellers. Its unique styling, a blend of rounded edges and a high roofline, also helped it stand out from conventional automobiles. The vehicle’s focus was not on outright performance, but on practicality and ease of use within an urban environment.
Engine & Performance
The 1998-2006 Smart Fortwo Coupe (C450) 0.7 i is powered by a 698 cc (42.59 cubic inches) inline three-cylinder gasoline engine, designated M 160.920. This engine produces 50 horsepower at 5250 rpm and 80 Nm (59 lb.-ft.) of torque at 1800 rpm. While modest by contemporary standards, this powertrain was designed for fuel efficiency rather than high performance. The engine features multi-port manifold fuel injection and an overhead camshaft (OHC) valvetrain with two valves per cylinder. A key feature of later iterations of this engine (though not initially in the C450) was the addition of a turbocharger, significantly boosting power output. The C450’s engine delivers a power-to-liter ratio of 71.6 hp/l. Power is delivered to the rear wheels via a six-speed automatic transmission. Acceleration from 0 to 100 km/h (0-62 mph) takes 18.3 seconds, and 0 to 60 mph is achieved in approximately 17.4 seconds. The top speed is limited to 135 km/h (83.89 mph). The weight-to-power ratio is 16.1 kg/Hp, and the weight-to-torque ratio is 10.1 kg/Nm.
Design & Features
The Smart Fortwo Coupe (C450) is a three-door coupe designed to accommodate two passengers. Its compact dimensions – 2500 mm (98.43 in) in length, 1515 mm (59.65 in) in width, and 1549 mm (60.98 in) in height – are central to its appeal. The wheelbase measures 1812 mm (71.34 in). The vehicle’s body structure incorporates a high-strength steel safety cell, designed to protect occupants in the event of a collision. Standard safety features included an Anti-lock Braking System (ABS). The interior, while minimalist, was designed to maximize space utilization. The Fortwo’s rear engine layout contributes to its unique handling characteristics and allows for a relatively spacious cabin despite its overall small size. The fuel tank capacity is 33 liters (8.72 US gallons), and the kerb weight is 805 kg (1774.72 lbs), with a maximum weight of 990 kg (2182.58 lbs) and a maximum load capacity of 185 kg (407.86 lbs). Tire sizes available were 145/65 R15 and 175/55 R15.
