Smart Fortwo III cabrio (A453) 0.9 (90 Hp) Automatic

The Smart Fortwo III Cabrio (A453) 0.9 is a city car manufactured by Smart, a microcar brand currently owned by Mercedes-Benz. Introduced in 2014 and produced through 2019, the A453 generation represented a significant evolution for the Fortwo, particularly in terms of design, safety, and efficiency. This two-seater Cabriolet, primarily marketed in Europe, offered a unique proposition: a compact, fuel-efficient, and stylish vehicle ideal for navigating congested urban environments. While not officially sold in the United States during this generation, the Fortwo has had limited runs in the US market in previous iterations, appealing to a niche audience seeking ultra-compact transportation.

Smart Fortwo III Cabrio (A453) 0.9: An Overview

The third generation Fortwo, and specifically the Cabrio variant, aimed to address criticisms of earlier models by offering improved build quality, a more refined driving experience, and enhanced safety features. The A453 chassis was a complete redesign, moving away from the shared platform with Renault’s Twingo (in earlier generations) and allowing Smart greater design flexibility. The 0.9-liter engine, a key component of this model, focused on delivering adequate performance with exceptional fuel economy, aligning with the Fortwo’s intended urban role. The Cabrio version added open-air enjoyment, further enhancing its appeal in favorable climates.

Engine & Performance

The Smart Fortwo III Cabrio 0.9 is powered by a 0.9-liter inline-three cylinder turbocharged gasoline engine, designated M 281.910. This engine produces 90 horsepower at 5500 rpm and 135 Nm (99.57 lb.-ft.) of torque at 2500 rpm. The engine’s turbocharger and intercooler contribute to its relatively sprightly performance despite its small displacement. Power is delivered to the rear wheels via a six-speed automatic transmission. Acceleration from 0 to 100 km/h (0-62 mph) takes 11.3 seconds, while 0-60 mph is achieved in approximately 10.7 seconds. The vehicle has a maximum speed of 155 km/h (96.31 mph). Fuel economy is a standout feature, with combined cycle consumption rated at 4.2 l/100 km (56 US mpg, 67.3 UK mpg), and CO2 emissions of 97 g/km, meeting Euro 6 emission standards. The engine’s power-to-weight ratio is 10.2 kg/Hp, and the torque-to-weight ratio is 6.8 kg/Nm.

Design & Features

The Smart Fortwo III Cabrio is a two-door, two-seater Cabriolet characterized by its exceptionally short length of 2695 mm (106.1 in). The body style is designed for maximum space efficiency, allowing for easy parking and maneuverability in tight urban spaces. The Cabrio top is a retractable fabric roof, offering an open-air driving experience. Safety features included in the A453 generation are a significant improvement over previous models, incorporating features like ABS (Anti-lock Braking System), and a robust safety cell structure. Interior features, while minimalist, were designed with practicality in mind. Trunk space ranges from a minimum of 260 liters (9.18 cu. ft.) to a maximum of 350 liters (12.36 cu. ft.) with the rear seats folded. The vehicle’s dimensions – a width of 1663 mm (65.47 in) and a height of 1552 mm (61.1 in) – contribute to its distinctive and recognizable silhouette. The McPherson strut front suspension and independent coil spring rear suspension provide a comfortable, if not sporty, ride. Steering is rack and pinion with electric power assistance.
