Order Book Opens in Germany for Audi A4 and A5 g-tron

Audi’s order book is now open for the new A4 Avant g-tron and the new A5 Sportback g-tron–two sustainable alternatives in the midsize category. Both models are powered by a bivalent 2.0 TFSI engine developing 170 hp.

Like the A3 Sportback g-tron that is already on the market, both vehicles can run on a choice of the climate-friendly fuel Audi e-gas, conventional CNG (compressed natural gas) or gasoline.

The newly developed engine is based on the gasoline-powered 2.0 TFSI with innovative combustion principle. Sporty, climate-friendly and economical – the new Audi A4 Avant g-tron and A5 Sportback g-tron meet all those requirements. They have a range of 950 kilometres (590.3 mi), of which up to 500 kilometres (310.7 mi) can be covered in the CNG mode.

Audi is presenting its g-tron technology at the IAA in Frankfurt in September.

The drive unit’s high efficiency means low costs of ownership: Fuel costs compared with an equivalent gasoline engine are much lower, at around four euros per 100 kilometres (62.1 mi) (Germany, as at: August 2017). The lower CO2 emissions also mean owners pay less in motor vehicle tax. In addition to being very economical to run, the new g-tron models have an extremely clean combustion process.

Thanks to their bivalent design, the g-tron models can cover up to 500 kilometres (310.7 mi) on natural gas in the NEDC cycle. When the pressure in the tank falls below 10 bar with about 0.6 kilogram (1.3 lb) of gas remaining, the engine management automatically switches to gasoline operation. This makes an extra range of more than 450 kilometres (279.6 mi) available. The high-strength, safe gas tanks made from carbon fibre-reinforced polymer (CFRP) and glass fibre-reinforced polymer (GFRP) are located beneath the rearward structure. They store 19 kilograms (41.9 lb) of gas at a pressure of 200 bar. Both models have a full-size luggage compartment: There is 415 litres (14.7 cu ft) of luggage capacity in the A4 Avant g-tron, and 390 litres (13.8 cu ft) in the A5 Sportback g-tron.

Audi e-gas

The g-tron models are especially eco-friendly when running on Audi e-gas. This synthetic fuel is produced using renewable energy from water and CO2 or from organic residual materials such as straw and plant clippings. During its production, Audi e-gas binds exactly the amount of CO2 emitted by the car. Audi offers this fuel for three years as a standard feature to customers ordering a g-tron model by May 31, 2018. They can fill up their g-tron model at any CNG filling station and pay the regular price. By feeding the computed volume of Audi e-gas into the natural gas grid, Audi ensures the green benefits of the program, including the corresponding reduction in CO2 emissions. With this deal, Audi is reducing the CO2emissions of the g-tron fleet when running on gas by up to 80 percent**.

Customers no longer require a special fuel card. Instead, Audi computes the volume automatically based on surveys and service data from the cars. TÜV Süd, a German testing and certification authority, monitors and certifies the process. Audi g-tron customers receive a document that confirms their car will be supplied with Audi e-gas and informs them about the certification.
