ion battery) of the latest generation with high
energy density
• Charging of high-voltage battery through
regenerative braking

Electric drive system of smart fortwo electric drive
Introduction of smart fortwo electric drive (3rd Generation) • Model Series 451
With a maximum torque of 130 Nm and acceleration
boost, the powerful electric motor provides good
driving performance and responsiveness.
Due to the output characteristics of the electric
motor, the smart fortwo electric drive only
requires a single fixed transmission ratio. This
makes gearshifting unnecessary. The motor
changes its direction of rotation for reverse
travel.
The high-voltage battery is installed between the
axles in the underfloor instead of a fuel tank. The
electric drive does not result in any space-
related limitations for the smart fortwo electric
drive; the interior compartment and trunk are
exactly the same size as on a smart fortwo with
combustion engine.
