The Volkswagen Twin Up! Concept gives us another a look into the future of the ultra-compact urban commuter segment. It is a plug-in hybrid version of the Up! variant. The Twin Up! shares the heart of the also futurist VW XL1 and is said to achieve over 200mpg using the new European Driving Cycle as a testing method. Debuting at the Tokyo Motor Show, this efficient plug-in concept represents Volkswagen's pursuit to become the leader in e-mobility by 2018.
Hybrid and electric system:
The Twin Up! shares parts from the XL1 including its diesel engine, electric motor and DSG dual-clutch automatic transmission. As the plug-in hybrid version of the Up!, the only modification made in the production version was to lengthen the short overhang by 1.2in.
The two-cylinder TDI engine is derived from the common rail four-cylinder, 1.6L diesel engine with bore spacing of 3.5in (88mm) and bore/stroke of 81x80.5mm. The 55kw drive unit consists of a 35kw 0.8L TDI clean Diesel engine, 35kw electric motor, DSG transmission and power electronics mounted at the front. Beneath the trunk is the fuel storage system, which includes an 8.6kWh lithium-ion battery, 12V battery for the electrical system and 8.7-gallon fuel tank.
The Hybrid module is located between the TDI engine and DSG transmission. The module consists of the electric motor and clutch that is integrated in the DSG housing in place of the flywheel. The electric motor is supplied with energy from a 8.6kWh lithium-ion battery. Power electronics, which operate at 308 volts, manage the flow of high-voltage energy between the battery and electric motor and convert direct current to alternating current.
In city driving and electric mode, the Twin Up! is claimed to go from 0-37mph in 8.8sec with a top speed of 78mph. In highway driving mode, the Twin Up! is claimed to go from 0-62mph in 15.7sec with a top speed of 87mph. In hybrid mode the car uses 159 lb-ft of torque.
The Twin Up! is highly efficient featuring thought-out aerodynamics, a low weight of 2657 lb and low rolling resistance 165/65 R15 tires. The Twin Up! also achieves superb energy efficiency by way of brake energy regeneration. The TDI engine is decoupled and shut off from drivetrain in electric mode. The clutch on the gearbox side remains closed and DSG is engaged during electric mode. Restarting the TDI engine occurs mid-driving. The electric motor's rotor speeds up and is coupled to the clutch in the 'pulse starting' process. This accelerates the diesel engine to start, seamlessly, unbeknownst to the driver. Using the new European Driving Cycle, a comparison driving cycle for plug-in hybrid vehicles in Europe, the Twin Up! achieved a stellar 214mpg - in all-electric mode its range is 31 miles.
The exterior is finished in a 'Sparking White' paint color that changes appearance due to blue 'Glass Flakes' within the paint. The blue theme, also seen on the inside, is continued using double stripes above the sill area.
The interior is dominated by a 'Ceramic' color. The seats feature a coordinated leather-fabric color and reflective strips in the center panels. The 'Think Blue' and 'e-mobility' theme appear throughout the interior with a blue double-piped line that frames the seats in addition to blue decorative stitching used on the multifunction steering wheel and trim for the shift lever.
The instrument cluster is purely digital and utilizes a visual image that changes based on whether the vehicle is in hybrid or electric mode. The central infotainment system includes an assortment of options such as contacts, 'sideway app,' energy efficiency, weather, air quality and climate control notices. The climate control function appears digital for the first time in a Volkswagen car, which can be adjusted via the central touchscreen.
With another highly efficient concept from Volkswagen, the future of the company as an e-mobility leader looks brighter than ever before.
