Thread: Radikalno 314 mpg VW XL1 pokazala

Revolucionarno novo dvosed dizel-električni hibridni je le 21g/km CO2 emisij in realnih gospodarstvo 127 mpg. To je lahek radikalno, VWs, VW XL1, ki obljublja gospodarstvo EU-certificirano 314mpg in 21g/km CO2 emisij, ko gre v omejene proizvodnje letos sledite svoje Ženevi avtomobilskem salonu pokažejo naslednji mesec.
Poganja motor TDI 47bhp dve-valja 800cc, podprta z 27bhp elektromotor in 5. 5kWh topniška jedinica zmašiti, dva sedeža avtomobila je trdil, da imajo Cd oceno samo 0. 189.
Iz tega izhaja, da je plug-in hibrid XL1 verjetno je najbolj ekonomičen in najbolj aerodinamično učinkovito proizvodnja avtomobilov vseh časov.
Prva prikazana kot teče koncept pred dvema letoma, je v lasti VW Karmann tovarni v Osnabrück, poleg VW Golf cabriolet in nov Porsche Boxster steznik carbonfibre XL1 gradijo.
Tehtanje šele 795kg, z XL1 je nekaj 3. 8m dolge in 1. 66m širok, kar pomeni, da je le malo manjša od VW Polo supermini. Vendar pa je samo 1. 15m visoko, nekaj 129 mm nižje od a Boxster. VW pravi, z XL1 je vrhu hitrosti omejena do 99. 4mph, ampak da lahko zadeti 62mph v samo 12. 7sec. Uporablja aluminij dvojnega wishbone spredaj vzmetenja, napol zaključnimi link suspenzijo zadaj, carbonfibre, ojačana plastična anti-roll bara in keramične zavornih kolutov.
Z XL1 lahko potujejo za 31 km samo na baterijo moč sam in je trdil paleto 310 km dizel in baterijo električnega skupaj, kljub temu, da majhen 10-litrski rezervoar za gorivo.

Grobo izračuni kažejo, da je je XL1 sposoben realnem v 127mpg v idealnih svetu pogojih, avtomobili 795kg teže vozila, svoje telo zelo spolzka v ozke pnevmatike v odpornost nizko varanje veter na kolesi iz magnezija, ukrep kateri tako 115/80 spredaj v 145/55 zadaj. Navodila za XL1s učinkovitost je da VW Temporary, zahteva le 8. 3bhp, da je sposobna vzdrževati stabilno 62 mph križarjenje.
Hibridni sistemi elektromotor v njegove namenske sklopka opremljenih med valjni dizelski dva 800cc motor v XL1s 7-DSG stopenjski menjalnik. Litij baterija ionska je vgrajena v nos avtomobila v imejte je mogoče ponovno napolniti, ko avto je zaviranje v prostem teku.
V čisto električni način, motorji sklopka v motornih disengages zaustavi. Motor je prinesel nazaj v življenje preko kaj VW klice začne impulz, kjer je električni motor zavrti ali visoke hitrosti v skupaj v motor, motor idled revolving pospeševanje hitrost zaganjanja gladko.
Skrajne ukrepe teže vključujejo varčevanje uporabo carbonfibre ojačana plastika za telo, koža, ki je samo 1. debeline 2 mm. aluminiju crash strukture tako spredaj v uporabljene zadaj v kot crash curke v vrata da absorbira vpliv sile.
Vetrobransko steklo je samo 3. debeline 2 mm. VW Aleš preverjenem gradnjo 227kg XL1s drivetrain (vključno z baterijo), 153kg podvozja, 105kg električni 80kg sistem na opremo z ladji, kot tako sedeži v tehnika merilni instrumenti v organ, ki tehta 230 kg. Kozarka, tudi armaturna plošča je izdelana iz iz, lahek ivernih, ki je samo 1. debeline 4 mm.
Pri prvem zagonu proizvodnje bo 50 avtomobilov, ki tako homologirana za prodajo popolnoma v snopiče. Po tem, mladeniška svežost pravijo, je zgrajen za zadovoljitev bo XL1 povpraševanja, čeprav VW še ni dal poljuben clue približno verjetno cena.

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.
