The Smart Fortwo II coupe (C451), produced from 2007 to 2014, represents the second generation of the iconic city car. Designed primarily for European urban environments, the Fortwo aimed to revolutionize personal transportation with its incredibly compact size and fuel efficiency. While never officially sold in large numbers in the United States, the C451 found a niche following among those seeking a uniquely maneuverable and economical vehicle. The Fortwo’s defining characteristic is its two-seat configuration and diminutive footprint, making it exceptionally easy to park and navigate congested city streets. This generation saw improvements in safety, build quality, and engine refinement compared to its predecessor.
Smart Fortwo II Coupe (C451): A Detailed Overview
The C451 Fortwo was a significant step forward for Smart, building upon the foundation laid by the original Fortwo (C450). It retained the core concept of a microcar but with a more sophisticated design and a wider range of available options. The vehicle’s rear-wheel-drive layout, coupled with its short wheelbase, contributed to its nimble handling. The 1.0-liter engine, while modest in power, was optimized for fuel economy, making the Fortwo an attractive option for environmentally conscious drivers. The C451 was available in various trim levels and special editions, catering to different tastes and budgets.
Engine & Performance
The 1.0i variant of the Smart Fortwo II coupe (C451) is powered by a naturally aspirated three-cylinder engine, designated M 132.910, displacing 999 cubic centimeters (60.96 cubic inches). This engine produces 71 horsepower (Hp) and boasts a power-to-weight ratio of 10.6 kg/Hp. The engine’s relatively small displacement and efficient design contribute to its impressive fuel economy figures. Fuel consumption is rated at 6.1 liters per 100 kilometers (38.6 US mpg) in urban conditions, 4.0 l/100 km (58.8 US mpg) on the extra-urban cycle, and a combined 4.7 l/100 km (50 US mpg). The engine is mated to a five-speed manual transmission, delivering power to the rear wheels. While not designed for high-speed performance, the Fortwo can achieve a maximum speed of 145 kilometers per hour (90.1 mph). The engine requires 3.7 liters (3.91 US qt) of engine oil, adhering to specific manufacturer specifications.
