The Audi A3 Sportback g-tron comes with the total gamut of Audi’s technology experience – from ultra-lightweight technology, and motion-picture show, to driver help systems. however 1st and foremost it showcases progressive CNG drive technology, beginning with the fuel storage. Its 2 tanks underneath the baggage compartment floor will every hold seven kilograms (15.43 lb) of CNG at a most two hundred bar pressure. In tune with the ultra-lightweight construction conception, every tank weighs twenty seven kilograms (59.52 lb) but its typical counterpart.

The tanks include a brand new variety of matrix. The inner layer consists of gas-impermeable polymeric amide compound, whereas a second layer of carbon fiber-reinforced compound (CFRP) provides the tank its extraordinarily high strength; a 3rd layer of fiber bolstered compound (GFRP) provides rugged protection against injury from the skin. High-strength epoxy glue is employed to bind the fiber bolstered materials.

A second highlight of the Audi A3 Sportback g-tron is its electronic pressure regulator. This compact and light-weight element reduces the high of the gas flowing from the cylinders all the way down to around 5 to 9 bar in 2 stages.

It ensures that the proper pressure is usually gift within the gas rail and at the gizmo valves – air mass for economical driving within the lower speed vary, and better once the driving force demand additional power and torsion.

If the pressure within the tank drops below 10 bar, the engine management system mechanically switches over to fuel operation. The Audi A3 Sportback g-tron is absolutely bivalent, i.e. its performance figures area unit identical in CNG and fuel modes.

CNG provides a variety – supported normal fuel consumption – of around four hundred metric linear unit (248.55 miles), with fuel providing another 900 metric linear unit (559.23 miles) if necessary; the entire vary is roughly on a par with Associate in Nursing Audi TDI. 2 displays within the instrument cluster give the driving force with up-to-date data on the stockpile in every of the tanks. the driving force system additionally displays the present fuel consumption supported the actual in operation mode.

The two filler necks area unit placed underneath a typical fuel flap. once provision, and whenever it's terribly cold, the engine is started with fuel at first, then it's changed to fossil fuel as quickly as attainable.

The engine relies on the new one.4 TFSI. Key modifications relate to the plate, turbocharging, injection system, and also the converter. Developing eighty one power unit (110 hp) and two hundred Nm of torsion, the Audi A3 Sportback g-tron features a high speed of one hundred ninety km/h (118.06 mph), with zero to a hundred km/h (0 - sixty two.14 mph) taking eleven seconds. The five-door automotive consumes on the average but three.5 kilograms per a hundred metric linear unit of CNG or Audi e-gas – the fuel that's generated from eco-electricity within the Audi e-gas project. greenhouse gas pipage emissions area unit but ninety five grams per metric linear unit (152.89 g/mile) in gas mode.

The greenhouse emission balance is even additional enticing in an exceedingly well-to-wheel analysis that accounts for all factors from the fuel supply to the car’s wheels. once the A3 Sportback g-tron is supercharged by Audi e-gas, no additional greenhouse gas is discharged than was with chemicals input in its production beforehand – making a closed-loop system. once the energy needed to make the e-gas facility and wind generation generators is enclosed in an exceedingly comprehensive analysis, greenhouse gas emissions area unit still but thirty grams per metric linear unit (48.28 g/mile).

Buyers of the Audi A3 Sportback g-tron can presumptively get the e-gas at the general public CNG provision stations via Associate in Nursing ecological accounting* methodology, the same as the tactic presently alive for getting eco-electricity.

With the e-gas project, Audi is that the 1st automobile manufacturer to develop a complete chain of property energy carriers. the beginning of the chain has electricity created from renewable energy sources; the tip product area unit H and also the artificial Audi e-gas. Construction of the world’s 1st works to supply artificial methane series (e-gas) from greenhouse gas and renewable electricity is sort of complete in Werlte (Emsland district of Lower Saxony), Germany.

The Audi e-gas plant uses the renewable electricity within the 1st stage for electrolysis – rending water into O and H (Audi e-hydrogen), that might in the future power fuel-cell vehicles. as a result of there's not however a widespread H infrastructure, however, the H is then reacted with greenhouse gas in an exceedingly methanation plant to supply renewable artificial methane series, or Audi e-gas. with chemicals speaking, this e-gas is a twin of fossil-based fossil fuel. As such, it are often distributed to CNG stations via the natural-gas network.

Thanks to the power-to-gas method, the electricity grid and gas network area unit being coupled bidirectionally for the primary time. heretofore whereas you'll generate electricity from gas, the reverse wasn't attainable. The Audi e-gas plant so paves the means for sound into the natural-gas network with its vast capability as a storage and transport system for thus far excess electricity capability.

The greenhouse gas employed in Audi’s e-gas plant may be a waste *product from a close-by biogas plant, operated by power utility EWE. The CO2, which might otherwise grime the atmosphere, is with chemicals warranted into the fuel at the Audi e-gas plant. The e-gas plant can annually turn out regarding one,000 metric loads of e-gas and can with chemicals bind some two,800 metric loads of greenhouse gas. This corresponds roughly to the number of greenhouse gas that 224,000 beech trees absorb in an exceedingly year.

The CO2-neutral e-gas from Werlte can power one,500 new Audi A3 Sportback g-tron vehicles fifteen,000 kilometers (9,320.57 miles) per annum. the ability trade also can take pleasure in Audi’s e-gas project, because it addresses the shrewish challenge of a way to store massive quantities of renewable electricity created from wind turbines and electrical phenomenon systems with efficiency and regardless of location. The electricity-gas cogeneration technology might considerably foster the growth of renewable energies
