For the 2009 model year, the Fortwo 61hp and 71hp will feature the firm's micro hybrid drive system as standard while Smart has also enhanced the minicar's equipment levels. When Smart says 'micro hybrid drive' or MHD for short, what the company means to say is an automatic start/stop start function. The system operates during the engine idling phases and promises to return fuel savings of up to 24% compared to the standard models and lower CO2 emissions to 103 grams per km. If the driver doesn't want to use the start and stop function, it can be deactivated through a switch on the center console until the next time the car is started.

Together with the micro hybrid drive Smart also performed a few minor upgrades in the Fortwo's interior. Changes include a redesigned instrument cluster with an enhanced LCD display and new net storage pockets in the driver and passenger doors, while the passion's "design red" interior trim has now also been updated to match the new "rally red" paint finish.

Furthermore, Smart added the "grey metallic" to the Fortwo's exterior color palette along with new optional 15" six-spoke alloy wheels.

In the U.K., the 2009 Fortwo 61hp and 71hp are available for order as a coupe and a cabrio in all three lines – pure, pulse and passion – with prices starting from £7,060 on the road.
