Volkswagen is planning to showcase its diesel electric hybrid city car at Tokyo motor show. The Twin-Up Concept, which is basically an advanced version of the entry-level VW Up supermini, will debut at the show scheduled for November 23 to December 1, 2013.
The Twin-Up Concept runs on a driveline which is a modified version of the plug-in diesel-electric hybrid. This driveline, which is being originally used in the advanced XL1, presents remarkable collective consumption of 214 mpg, as claimed, on the Euro combined cycle together with a zero-emissions electric range of 31 miles.
The four-seater Twin-Up is among a series of alternative drive models under development at Volkswagen. Hans-Jakob Neusser, head of Volkswagen’s R&D operations stated that the Twin-Up model is an engineering prototype with future production potential. He further said that the elements of the futuristically styled XL1’s hybrid system are used, although various components have been modified to offset the compact hatchback’s added weight.
The Twin-Up Concept is fitted with an upgraded electric motor consisting of a bigger battery with two added modules. This has raised its capacity to 8.6 kWh. The car also possesses a diesel fuel tank that boasts of an additional 6.1 gallons of capacity for a total of 8.7 gallons.
The car gets its power from the same engine being used in the XL1, which is the two-cylinder turbocharged 800cc common rail diesel engine. The car produces torque of 47 hp and 88 lb-ft.
For the combined system output, the Twin-Up boasts 74 hp and 158 lb-ft. However, the drive is guided through a seven-speed dual clutch gearbox attached to the front wheels.
As per claims made by Volkswagen, the Twin-Up, which is still in its early stages of development, accelerates from 0-37 mph in 8.8 seconds and 0-62 mph in 15.7 seconds. The top speed that the car reaches is limited to 87 mph in hybrid mode.
The car releases average CO2 emissions of less than 17 g/mile. For distances up to 31 miles and speeds up to 78 mph, the car can select pure electric propulsion via its e-mode function.
The Tokyo motor show is expected to see a more production-oriented version of the Twin-Up along with the recently unveiled all-electric e-Up.
