Diesel models
Smart cars are known for their fuel efficiency, and their light weight significantly influences their fuel efficiency. The standard models are based on the European-born Smart Fortwo designs. The 2017 model of the Smart EQ Fortwo has a fuel efficiency of 33/38/35 MPG for city/highway/combined. The 5-speed manual is slightly less efficient with 31/38/34 MPG. The 2009 model of the same variant has a fuel efficiency of 33.1 MPG. The 2014 Smart diesel model, the fortwo cdi, has a fuel efficiency of 85.6 MPG, which means it can travel 670 miles between fill-ups. This is thanks to the development of the world's smallest direct injection diesel engine. The diesel model is available in Europe in both coup and cabrio versions.
The Smart Fortwo has an automated manual transmission that can be shifted by computer or manually with the gear selector or wheel-mounted paddle shifters. The paddle shifters may get a bit confusing if you like to shift while turning, but overall they make the driving experience much better. You can shift up earlier than you would ever expect in an auto and shift down early for engine braking. The transmission even disengages its auto-creep function when you are stopped at lights. To get speed out of the Fortwo’s 1.0-liter, 70hp engine, the car has quite short gearing. This means revving up quickly and shifting often if you want to drive efficiently.
The fuel efficiency of a smart car can also depend on the driving style. For example, driving at 55 mph and taking 30 minutes to get somewhere puts you at a great point of efficiency in terms of fuel economy. Past 55 mph, wind resistance increases exponentially. You save only a few minutes going 65 or 75 but lose 20+% efficiency. Additionally, the car is very sensitive to how you drive. If you are revving it out to 3000 rpm in every gear, you won't get great mileage.
