The new Fortwo Cabrio will arrive at Smart dealerships in the U.S. in early summer of 2016.
Pricing has not been announced.
The key element of the Fortwo Cabrio is what Smart is calling a "tritop" fabric soft top that is larger than the one on the outgoing model. The top can be automatically opened in 12 seconds, even when driving at top speed.
The soft top can also be opened from outside the car by remote control.
Side roof bars must be removed for maximum open space. They can be stowed on the inside of the tailgate.
The convertible gets structural modifications compared to the coupe version. Torsional strength has been improved by around 15 percent compared with the previous model.
Modifications include a large steel cross under the vehicle, two torsional bulkheads under the front and rear, and an inner tube in the A-pillars made of high-strength hot-formed steel.
The National Highway Traffic Safety Administration has not crash-tested the 2016 Fortwo Cabrio.
The Fortwo Cabrio is equipped with a three-cylinder engine rated at 89 horsepower and 100 pound-feet of torque. The engine is linked to either a five-speed manual transmission or six-speed automatic transmission.
Top speed is pegged at 96 mph.
The EPA has not rated this version of the 2016 Smart Fortwo.
Buyers can choose from four trim levels: Pure, Passion, Prime and Proxy.
Standard features include automatic climate control, power windows, cruise control and LED daytime running lights.
A wind deflector and forward-collision warning system are options.
Edmunds says: Convertible shoppers making long-range plans may want to consider this latest take on the Fortwo convertible.
