Audi A3 Sportback g-tron: Starting a New Model Year with a Longer CNG Range

The Audi A3 Sportback g-tron forms partial of an integrated and tolerable mobility judgment from a code with a 4 rings. Equipped with a new 1.5 TFSI engine producing 96 kW (131 metric hp), a A3 Sportback g-tron sets standards for potency and economy. To capacitate a four-cylinder engine to run on these fuels, Audi engineers mutated a cylinder head, turbocharging, fuel injection complement and catalytic converter. Compared to gasoline, explosion of healthy gas emits 25 percent reduction CO2 due to a lowest CO calm of all hydrocarbons. In addition, particulate emissions sojourn really low.

Long operation interjection to third gas tank
Just as before, there are dual tanks done of potion fiber-reinforced polymer (GFRP/CFRP) underneath a luggage cell building of a five-door car, any of that reason roughly seven kilograms (15.4 lb) of gas. They revoke luggage space usually marginally and are assembled from a multiple material, creation them really lightweight. In a new Audi A3 Sportback g-tron, an additional steel cylinder filled with four kilograms (8.8 lb) of CNG extends a operation during gas operation. Reducing a distance of a gasoline tank not usually frees adult a required space for this additional gas tank, it also creates a new Audi A3 Sportback g-tron a quasi-monovalent vehicle. Using a specific advantages and measure of any of a dual tank technologies to a advantage, a intelligent multiple of GFRP tanks and a gas tank creates best use of a existent designation space. The gasoline tank, that now binds nine liters (2.4 US gal), provides a required mobility reserve.

Strict reserve requirements
The dual cosmetic tanks storing a gas with an handling vigour of adult to 200 bar follow a Audi lightweight pattern philosophy. Thanks to their layout, they import 66 percent reduction than allied steel cylinders. Their middle covering is a gas-tight polyamide bladder. 

The load-bearing fiber-reinforced laminate consists of an middle covering of CO fiber-reinforced polymer (CFRP) and a covering of potion fiber-reinforced polymer (GFRP) on top. This multiple ensures ultra-high strength. Using GFRP not usually improves stability, a multiple element is also a arguable visible indicator of damage. Following an focus of force from a outside, for instance in a eventuality of an accident, a tone of a covering changes to a milky-white. Before being commissioned in a car, any tank is subjected to a hydraulic exam during 300 bar during production. The normal detonate vigour of 580 bar is distant aloft than this and exceeds a authorised mandate of 470 bar by far.

Convenient operation
The filler necks for gas and gasoline are located underneath a common tank flap. Two indicators surprise a motorist about a fill levels of a tanks. The motorist information complement shows a fuel expenditure in a active handling mode.

The Audi A3 Sportback g-tron arrives during a patron versed with a seven-speed S tronic. In Germany, a Audi A3 Sportback g-tron costs EUR 30,600 and is accessible to sequence commencement March 7.
