Llinyn Crys polo Volkswagen i gael ategyn hybrid a phŵer nwy naturiol

Cadarnha cawr ceir o'r Almaen gynlluniau i ddatblygu amrywiolion ffriwgal o'i uwchmini i ychwanegu at betrol safonol ac ystod diesel Plug-in hybrid a fersiynau nwy naturiol cywasgedig (CNG) o'r Volkswagen Polo yn cael eu tipio i gyrraedd cynhyrchiant y flwyddyn nesaf.
Yn ystod lansiad swyddogol yr ystod Polo newydd ym mhencadlys Volkswagens yn Wolfsburg, yr Almaen, cadarnhaodd y cwmni fod y ddwy ffynhonnell bŵer amgen yn cael eu datblygu ar gyfer yr uwchmini.
Ategyn Volkswagens mae technoleg hybrid yn eistedd o dan yr enw ymbarél TwinDrive a gellir cyfuno'r system â pheiriannau llosgi petrol neu ddisel.
Mae'r cwmni Wolfsburg eisoes wedi dangos sawl hybrid plygio i mewn gan gynnwys y GTE Golff – sy'n priodi 148bhp 1. Injan betrol chwistrellu uniongyrchol pedwar-silindr 4 litr gyda modur trydan 107bhp – y Twin Up, a ddefnyddiodd dechnoleg diesel yn deillio o ddwy sedd uwch-ffriwgal XL1, a SUV CrossBlue.
Ni fyddai Volkswagen yn cael ei dynnu ar fanylion y system y bydd y Polo yn ei mabwysiadu, y tu hwnt i ddweud y bydd yn wahanol i'r un a fabwysiadwyd ar gyfer y Golff. Un rheswm allweddol am hyn yw bod y cerbyd olaf yn seiliedig ar blatfform MQB modiwlaidd Volkwagens, tra bod Polo'r genhedlaeth bresennol yn dal i ddefnyddio'r tanategu PQ25 hŷn.
Bydd y dechnoleg yn wahanol, meddai Ekkehard Pott o dîm datblygu pwerdy Volkswagen. Nid oes gennym yr un platfform, felly mae'n rhaid i ni wneud addasiadau sy'n benodol i gerbydau.
Credai Pottiau y gallai'r system hybrid plygio i mewn weithio'n dda gydag uwchmini fel y Polo, lle gellid ymgymryd â theithiau trefol ar bŵer trydan tawel.
Un o'r manteision fyddai economi tanwydd, wrth gwrs ond un arall fyddai cysur. Mae gyrru ar drydan pur dros bellteroedd byrrach yn rhywbeth y gallai TwinDrive ei gynnig mewn ffordd dda iawn, meddai.
Gallai datblygu system hybrid plygio i mewn mewn uwchmini y gellir ei werthu am gost gystadleuol fod yn her mewn segment marchnad gydag elw cul.
Er y gellir paru system ategyn Volkswagens naill ai â injan hylosgi mewnol petrol neu ddisel, mae'n ymddangos bod y cyfuniad o losgi olew – yn draddodiadol yn ddrutach nag unedau petrol – a'r dechnoleg ategyn yn awgrymu bod ategyn petrol yn gwneud synnwyr.
Hyd yma, mae TwinDrive wedi'i ddangos gyda thechnoleg petrol, meddai Pott. Wrth gwrs, byddai cost y dechnoleg yn bryder – mae'n rhaid i ni benderfynu ar gyfer pob prosiect beth fyddai'r cyfuniad mwyaf ystyrlon.
Mae Volkswagen hefyd yn asesu ei dechnoleg nwy naturiol gywasgedig (CNG) i'w gosod yn y Polo. Gwelwyd y system gyntaf yn y Golff TGI BlueMotion a ddangoswyd gyntaf yn sioe echddygol Genefa y llynedd. Defnyddiodd y car hwnnw 1. injan TSI 4 litr a allai gymryd naill ai petrol neu CNG.
Mae pethau'n dal i gael eu datblygu, ond os bydd rhagolygon da ar gyfer TGI a TwinDrive byddwn yn dadorchuddio mwy o'r manylion y flwyddyn nesaf, meddai Pott.

German car giant confirms plans to develop frugal variants of its supermini to augment standard petrol and diesel range Plug-in hybrid and compressed natural gas (CNG) powered versions of the Volkswagen Polo are tipped to reach production next year.
During this weeks official launch of the refreshed Polo range at Volkswagens headquarters in Wolfsburg, Germany, the company confirmed that the two alternative power sources are being developed for the supermini.
Volkswagens plug-in hybrid technology sits under the umbrella name TwinDrive and the system can be combined with either petrol or diesel combustion engines.
The Wolfsburg-based company has already shown off several plug-in hybrids including the Golf GTE – which marries a transversely mounted 148bhp 1. 4-litre four-cylinder direct-injection petrol engine with a 107bhp electric motor – the Twin Up, which used diesel technology derived from the super-frugal XL1 two-seater, and the CrossBlue SUV.
Volkswagen wouldnt be drawn on details of the system the Polo will adopt, beyond saying that it will be different to that adopted for the Golf. One key reason for this is because the latter vehicle is based on Volkwagens modular MQB platform, whereas the current-generation Polo still uses the older PQ25 underpinnings.
The technology will differ, said Ekkehard Pott of Volkswagen's powertrain development team. We dont have the same platform, so we have to make vehicle-specific adaptions.
Potts believed the plug-in hybrid system could work well with a supermini such as the Polo, where urban journeys could be undertaken on silent electric power.
One of the advantages would be fuel economy, of course but another one would be comfort. Driving on pure electricity over shorter distances is something that TwinDrive could offer in a very good way, he said.
Developing a plug-in hybrid system in a supermini that can be sold at a competitive cost could prove to be a challenge in a market segment with narrow profit margins.
Although Volkswagens plug-in system can be paired to either a petrol or diesel internal combustion engine, the combination of an oilburner – traditionally more expensive than petrol units – and the plug-in technology would seem to suggest that a petrol plug-in makes sense.
Until now TwinDrive has been shown with petrol technology, said Pott. Of course the cost of the technology would be a concern – we have to decide for every project what the most meaningful combination would be.
Volkswagen is also assessing its compressed natural gas (CNG) technology for installation in the Polo. The system was first seen in the Golf TGI BlueMotion first shown at the Geneva motor show last year. That car used a 1. 4-litre TSI engine that could take either petrol or CNG.
Things are still under development, but if there proves to be an good outlook for TGI and TwinDrive we will unveil more of the details next year, said Pott.
