The Smart Fortwo III coupe (C453), specifically the 0.9-liter (90 horsepower) variant, represents a significant evolution in the microcar segment. Produced from 2014 to 2019, this generation of the Fortwo was designed to address criticisms of earlier models, focusing on improved build quality, enhanced safety features, and a more refined driving experience. While primarily marketed in Europe as a solution to urban congestion and parking challenges, the Fortwo has garnered a niche following in the United States, appealing to buyers seeking an exceptionally fuel-efficient and compact vehicle.
Smart Fortwo III Coupe (C453) 0.9: An Overview
The C453 Fortwo marked a departure from the previous generation’s collaboration with Renault. This iteration was developed largely independently by Smart, resulting in a vehicle with a distinct character. The Fortwo’s core concept remained unchanged: a two-seat, rear-engine, rear-wheel-drive city car designed for maximum maneuverability and minimal environmental impact. The 0.9-liter engine, a turbocharged three-cylinder unit, became the mainstay of the range, offering a balance of performance and economy.
Engine & Performance
The heart of the Smart Fortwo III 0.9 is the M 281.910, a 0.9-liter turbocharged inline-three cylinder gasoline engine. This engine produces 90 horsepower at 5500 rpm and 135 Nm (99.57 lb.-ft.) of torque at 2500 rpm. The turbocharger and intercooler contribute to a surprisingly responsive power delivery for a vehicle of this size. Power per liter is a notable 100.2 Hp/l. The engine is mated to a 5-speed manual transmission, driving the rear wheels. Acceleration from 0 to 60 mph takes approximately 9.9 seconds, and 0-100 km/h (0-62 mph) is achieved in 10.4 seconds. The top speed is electronically limited to 155 km/h (96.31 mph). Fuel economy is a key strength, with combined cycle consumption rated at 4.2 l/100 km (56 US mpg, 67.3 UK mpg, 23.8 km/l). CO2 emissions are rated at 97 g/km, meeting Euro 6 emission standards.
Design & Features
The C453 Fortwo coupe maintains the iconic short-wheelbase, two-door coupe body style that defines the model. Its compact dimensions – 2695 mm (106.1 in) in length and 1663 mm (65.47 in) in width – make it exceptionally easy to park and maneuver in tight urban environments. The rear-engine layout contributes to the car’s unique handling characteristics. Inside, the C453 offered a more refined interior compared to its predecessors, with improved materials and a more modern dashboard design. Standard features included ABS (Anti-lock braking system), electric power steering, and a basic infotainment system. Safety features were also enhanced, with the C453 incorporating a more robust safety cell and improved crash protection. Trunk space, while limited, ranges from 260 liters (9.18 cu. ft.) to 350 liters (12.36 cu. ft.) depending on seat configuration. The vehicle’s kerb weight is 840 kg (1851.88 lbs), with a maximum permissible weight of 1170 kg (2579.41 lbs).
