2005 Smart Fortwo

The 2005 Smart Fortwo, also known as the Smart City-Coupé, is a microcar known for its compact size and fuel efficiency. The primary engine option for this model year is a 698cc three-cylinder turbocharged gasoline engine, producing around 61 horsepower and 70 lb-ft of torque. It was also available with a diesel engine in some markets, but we will focus on the gasoline model here.
