Tokyo Motor Show official: VW Twin-Up image

Volkswagen has formally introduced the hybrid Twin-Up model during the 2013 Tokyo Motor Show, exhibited next to the all-electric e-Up.

According to the company, the model has the potential to become a production one, as it is technically related to the revolutionary XL1 – Twin-Up weighs 1,205 kg (2,656 lbs), which makes it 410 kg (904 lbs) heavier than the former. Power comes from the same two-cylinder 800cc common-rail diesel engine from the XL1 installed transversally in the engine bay. The motor produces 47 hp (35 kW) and 88 lb-ft (119 Nm) of torque.

It also benefits from an upgraded electric motor developing 47 hp (20 hp more than in the XL1) and 103 lb-ft (139 Nm) and an 8.6 kWh battery while the diesel fuel tank has a capacity of 33 liters, making it 23 liters bigger than the one in the XL1.

The Twin-Up has a combined power of 74 hp (55 kW) and 158 lb-ft (214 Nm) sent to the front axle through a dual-clutch seven-speed gearbox. According to Volkswagen, the Twin-Up gets from 0 to 37 mph (59.5 km/h) in 8.8 seconds, while the 0-62 mph (0-100 km/h) task is accomplished in 15.7 seconds, prior to reaching a top speed electronically-capped at 87 mph (140 km/h) in hybrid mode.

Also, official figures say the car can return an impressive 257-mpg UK (214 mpg US or 1.1 liters / 100 km) with CO2 emissions of only 27 g/km. The all-electric range is up to 31 miles (50 km), with speeds of up to 78 mph (125.5 km/h).
