Volkswagen recently showcased the hybrid concept of its up! city car equipped with the powertrain from the XL1 concept at the 2013 Tokyo Motor Show.
Originally launched in 2011 with a 1.0-liter 3-cylinder gas engine, it only needed minor modifications for accommodate the plug-in hybrid drivetrain, which along with the two-cylinder engine produces 35 kW each. Together, it can produce a maximum output of 55 kW with peak torque of 215 Nm.
All the power from the front-mounted drivetrain is coursed through a seven-speed dual clutch transmission. Found between the rear seats and the boot are the 8.6 kWh lithium-ion battery pack, 12 V battery and 33-liter fuel tank.
Excellent fuel consumption is achieved through a .30 coefficient of drag, low curb weight of 1,205 kg, and optimized tires for low rolling resistance. The combination achieves a fuel economy of up to 109 kilometers to a liter of fuel.
The engine can work independently from the electric motor and vice-versa, allowing an emission-free ride when the e-mode is turned on.
E-mode can take you as far as 50 kilometers while 124 km/h is the maximum speed and it will accelerate from zero to 60 km/h in 8.8 seconds.
When both the diesel engine and the electric motor are used simultaneously, the hybrid up! can accelerate from zero to 100 km/h in 15.7 and reach a top speed of 140 km/h.
