Volkswagen AG will use this month's Tokyo auto show to reveal a prototype Up! supermini fitted with an upgraded version of the plug-in diesel-electric hybrid powertrain used in the company's 260-mpg XL1 concept car.
Hans-Jakob Neusser, head of VW R&D, tells Autocar the four-seat engineering prototype, called the Twin-Up, is fitted with a higher-output electric motor and a larger battery to handle the Up's additional 900 lbs compared to the extremely lightweight XL1.
Engine power comes from the same turbocharged 47-hp, 88 lb-ft 800cc 2-cylinder diesel used in the XL1. The electric motor develops 47 hp (20 more than the XL1 motor) and 103 lb-ft of torque. Output is channeled to the front wheels through a 7-speed dual-clutch gearbox.
VW says the Twin-Up can accelerate from 0 to 62 mph in a 15.7 seconds and reach a top speed of 87 mph in hybrid mode. The company claims an average 257 mpg on the European test procedure. The car is capable of traveling as far as 31 miles on electric power.
