Arriving at dealerships this autumn, the Smart Fortwo Cabrio will be the least expensive convertible available on the market.

Equipped with a standard five-speed manual transmission, the diminutive two-seater will start at $19,650, or $20,640 with the optional six-speed dual-clutch automatic. The pricing includes destination fees.

Last offered in the U.S. in 2015, the Fortwo Cabrio is touted for the three-in-one versatility of its new “Tritop” roof. Operated at the touch of a button or remotely activated using a fob, drivers can select to travel with the top fully open, fully closed or partially open. Convertible soft tops are available in black and red no extra cost.

Power for the Fortwo Cabrio is provided by a 0.9 liter turbocharged three cylinder engine that offers 89 horsepower and 100 pound-feet or torque. Zero to 60 mph acceleration is 10.4 seconds.

Featuring an updated platform, the 2017 model now includes Crosswind Assist to help account for gusts, and Hill-Start Assist to prevent rollaway on gradients. A forward collision warning system is now optionally available.

The Fortwo Cabrio will be offered in three trim levels: Passion, Prime and Proxy.
