Iħjut Ir-radikali 314mpg VW XL1 żvelat

Ibridu diżil-elettriku ġdid rivoluzzjonarju b'żewġ sedili għandu emissjonijiet ta 'CO2 ta' 21g / km biss u ekonomija tad-dinja reali ta '127mpg. Dan huwa VWs radikali, ħfief, VW XL1 li twiegħed ekonomija ċċertifikata mill-UE ta 'emissjonijiet ta' CO2 ta '314mpg u 21g / km meta tidħol fi produzzjoni limitata aktar tard din is-sena ssegwi l-ispettaklu tal-mutur ta' Ġinevra tagħha jiżvela x-xahar id-dieħel.
Imħaddem b'magna TDI b'żewġ ċilindri ta' 47bhp ta' 800cc appoġġata minn mutur elettriku ta' 27bhp u 5. Pakkett tal-batterija ta '5kWh, il-karozza b'żewġ sedili hija ddikjarata li għandha klassifikazzjoni Cd ta' 0 biss. 189.
Ir-ritratt huwa li l-ibridu plug-in XL1 huwa probabbilment l-iktar karozza ta 'produzzjoni ekonomika u l-aktar aerodinamika effiċjenti ta' kull żmien.
Muri għall-ewwel darba bħala kunċett operattiv sentejn ilu, l-XL1 bodied-carbonfibre qed jinbena fil-fabbrika Karmann proprjetà tal-VW f'Osnabrück, flimkien mal-cabriolet VW Golf u l-Porsche Boxster il-ġdid.
Li jiżen biss 795kg, l-XL1 huwa xi 3. 8m twil u 1. 66m wiesgħa, li jfisser li huwa biss marġinalment iżgħar minn supermini VW Polo. Madankollu, huwa biss 1. 15m għoli, xi 129mm inqas minn Boxster. VW tgħid li l-XL1 għandu l-ogħla veloċità tiegħu limitata għal 99. 4mph, iżda li jista 'jolqot 62mph fi 12 biss. 7sec. Juża sospensjoni ta 'quddiem ta' wishbone doppja tal-aluminju, sospensjoni ta 'link semi-trailing fuq wara, vireg tal-plastik rinfurzati bil-carbonfibre u diski tal-brejk taċ-ċeramika.
L-XL1 jista 'jivvjaġġa għal 31 mil biss fuq il-qawwa tal-batterija biss u għandu firxa ddikjarata ta' 310 mili fuq il-qawwa tad-diżil u tal-batterija flimkien, minkejja li għandu tank tal-fjuwil ċkejken ta '10 litri.

Kalkoli mhux maħduma jissuġġerixxu li l-XL1 huwa kapaċi 127mpg fid-dinja reali f'kundizzjonijiet ideali, prodott tal-karozzi piż tal-bankina ta '795kg, il-ġisem tiegħu li jiżloq ħafna u tajers dojoq ta' reżistenza baxxa fuq roti tal-manjeżju, li jkejlu biss 115/80 fuq quddiem u 145/55 fuq wara. Gwida għall-effiċjenza XL1s hija li VW ssostni li teħtieġ biss 8. 3bhp biex tkun tista 'żżomm kruċiera stabbli ta' 62mph.
Is-sistemi ibridi mutur elettriku u l-klaċċ dedikat tiegħu huma mwaħħla bejn il-magna diesel b'żewġ ċilindri 800cc u l-gearbox DSG b'seba 'veloċitajiet XL1s. Il-batterija tal-jone tal-litju hija mmuntata fl-imnieħer tal-karozza u tista 'tiġi ċċarġjata mill-ġdid meta l-karozza tkun qed tibbrejkja u tmiss.
Fil-modalità purament elettrika, il-magni klaċċ disengages u l-mutur jingħalaq. Il-magna terġa 'tieħu l-ħajja permezz ta' dak li VW isejjaħ startjar tal-polz, fejn il-mutur elettriku jdur sa veloċità għolja u huwa akkoppjat lura mal-magna, u jaċċellera l-magna idled għall-veloċità rotanti meħtieġa għall-istartjar bla xkiel.
Il-miżuri estremi li jiffrankaw il-piż jinkludu l-użu ta 'plastik rinfurzat bil-carbonfibre għall-ġisem, li l-ġilda tiegħu hija biss 1. 2mm ħoxnin. L-istrutturi tal-kraxx tal-aluminju jintużaw quddiem u wara u bħala travi tal-kraxx fil-bibien, biex jassorbu l-forzi tal-impatt.
Il-windskrijn huwa biss 3. 2mm ħoxnin. VW tgħid li l-kostruzzjoni XL1s tinqasam fi drivetrain ta '227kg (inkluża l-batterija), 153kg running gear, sistema elettrika ta' 105kg, 80kg ta 'tagħmir abbord, bħal sedili u strumenti, u korp li jiżen 230kg. Anke d-daxxbord huwa magħmul minn materjal tal-fibra tal-injam ħafif li huwa biss 1. 4mm ħoxnin.
L-ewwel produzzjoni se tkun ta' 50 karozza, li huma kompletament omologati għall-bejgħ fl-Ewropa. Wara dan, sorsi jgħidu li l-XL1 se jinbena biex jissodisfa d-domanda, għalkemm VW għad trid tagħti xi ħjiel dwar il-prezz probabbli.

Revolutionary new two-seater diesel-electric hybrid has CO2 emissions of just 21g/km and real world economy of 127mpg. This is VWs radical, lightweight, VW XL1 which promises an EU-certified economy of 314mpg and 21g/km CO2 emissions when it goes into limited production later this year follow its Geneva motor show reveal next month.
Powered by a 47bhp two-cylinder 800cc TDI engine backed up by a 27bhp electric motor and 5. 5kWh battery pack, the two-seat car is claimed to have a Cd rating of just 0. 189.
The upshot is that the plug-in hybrid XL1 is probably the most economical and most aerodynamically efficient production car of all time.
First shown as a running concept two years ago, the carbonfibre-bodied XL1 is being built at the VW-owned Karmann factory in Osnabrück, alongside the VW Golf cabriolet and the new Porsche Boxster.
Weighing just 795kg, the XL1 is some 3. 8m long and 1. 66m wide, which means it is only marginally smaller than a VW Polo supermini. However, it is only 1. 15m high, some 129mm lower than a Boxster. VW says the XL1 has its top speed limited to 99. 4mph, but that it can hit 62mph in just 12. 7sec. It uses aluminium double wishbone front suspension, a semi-trailing link suspension at the rear, carbonfibre reinforced plastic anti-roll bars and ceramic brake discs.
The XL1 can travel for 31 miles just on battery power alone and has a claimed range of 310 miles on diesel and battery power combined, despite having a tiny 10-litre fuel tank.

Rough calculations suggest that the XL1 is capable of a real-world 127mpg in ideal conditions, a product of the cars 795kg kerb weight, its very slippery body and wind-cheating and low resistance narrow tyres on magnesium wheels, which measure just 115/80 at the front and 145/55 at the rear. A guide to the XL1s efficiency is that VW claims it requires just 8. 3bhp to be able to maintain a steady 62mph cruise.
The hybrid systems electric motor and its dedicated clutch are fitted between the 800cc two-cylinder diesel engine and the XL1s seven-speed DSG gearbox. The lithium-ion battery is mounted in the nose of the car and can be recharged when the car is braking and coasting.
In pure electric mode, the engines clutch disengages and the motor shuts down. The engine is brought back to life via what VW calls pulse starting, where the electric motor spins up to high speed and is coupled back to the engine, accelerating the idled engine to the revolving speed required for smooth starting.
The extreme weight-saving measures include using carbonfibre reinforced plastic for the body, the skin of which is just 1. 2mm thick. Aluminium crash structures are used front and rear and as crash beams in the doors, to absorb impact forces.
The windscreen is just 3. 2mm thick. VW says the XL1s construction breaks down into a 227kg drivetrain (including the battery), 153kg running gear, 105kg electrical system, 80kg of on-board equipment, such as seats and instruments, and a body that weighs 230kg. Even the dashboard is made from a lightweight wood fibre material thats just 1. 4mm thick.
The first production run will be of 50 cars, which are fully homologated for sale in Europe. After that, sources say the XL1 will be built to meet demand, though VW has yet to give any clue about the likely price.
