Golwg argraffadwy
Mae VW yn amlinellu cynlluniau i greu fersiwn 250mpg o'r Up gan ddefnyddio gêr rhedeg y XL1. Bydd VW yn ffitio trên gyriant hybrid plug-in dwy silindr y XL1 radical i mewn i'r car Up City. Mae'r XL1 yn cael ei bweru gan injan dau-silindr, 47bhp, TDI gyda chefnogaeth modur trydan 27bhp a 5. Pecyn batri 5kWh. Volkswagen ffynonellau yn dweud y gall y Cynnydd super-frugal gael sgôr economi swyddogol yr UE o bron i 1-litr / 100km - 250mpg tebygol ar y cylch prawf NEDC. Gyda'r safon Up yn pwyso dim ond 925kg - dim ond 130kg drymach na'r ffibr carbon corffedig XL1 - mae'r Uphybrid yn debygol o ddod i mewn o dan 1000kg. Dylai hyn a'r trên gyrru newydd sicrhau bod gan y Up Hybrid yr economi byd go iawn gorau o unrhyw gar confensiynol. Mae amcangyfrifon bras yn awgrymu y dylai dros 90mpg fod yn bosibl mewn amodau delfrydol. Mae gan y system hybrid newydd hon modur trydan a chydiwr pwrpasol sydd wedi'u gosod rhwng yr injan diesel dau silindr 800cc a'r blwch gêr DSG 7-cyflymder. Bydd y batri lithiwm-ion yn cael ei osod yng nghefn y Up a gellir ei ailwefru pan fydd y car yn brecio ac yn arfordira. Mewn modd trydan pur - a ddylai gynnig ystod o tua 30 milltir - mae'r peiriannau cydio yn disengages ac mae'r modur yn cau i lawr. Mae'r injan yn cael ei ail-ddechrau gan pwls gan ddechrau lle mae'r modur trydan yn troelli hyd at gyflymder uchel, gan gyflymu'r injan idled i'r cyflymder cylchdroi sy'n ofynnol ar gyfer cychwyn llyfn. Mae'r Uphybrid yn dal i fod yn y cam peirianneg ac ni ddisgwylir iddo fynd ar werth am 18 mis arall. Nid yw ffynonellau VW wedi rhoi unrhyw gliwiau ynghylch prisio'r Up Hybrid tebygol. VW outlines plans to create a 250mpg version of the Up using the XL1's running gear. VW will fit the two-cylinder plug-in hybrid drivetrain of the radical XL1 into the Up city car. The XL1 is powered by a two-cylinder, 47bhp, TDI engine backed up by a 27bhp electric motor and 5. 5kWh battery pack. Volkswagen sources say that the super-frugal Up may get an official EU economy rating of nearly 1-litre/100km — a likely 250mpg on the NEDC test cycle. With the standard Up weighing just 925kg - only 130kg heavier than the carbonfibre bodied XL1 - the Up hybrid is likely to come in under 1000kg. This and the new drivetrain should ensure that the Up Hybrid has the best real-world economy of any conventional car. Rough estimates suggest that over 90mpg should be possible in ideal conditions. Attachment 5326 This new hybrid system has an electric motor and a dedicated clutch that are fitted between the 800cc two-cylinder diesel engine and the 7-speed DSG gearbox. The lithium-ion battery will be mounted in the rear of the Up and can be recharged when the car is braking and coasting. In pure electric mode - which should offer a range of around 30 miles - the engines clutch disengages and the motor shuts down. The engine is re-started by pulse starting where the electric motor spins up to high speed, accelerating the idled engine to the revolving speed required for smooth starting. The Up hybrid is still at the engineering stage and is not expected to go on sale for another 18 months. VW sources have given no clues as to the likely pricing of the Up Hybrid.
