City car gets a boost with low emission economical engine
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.
