Audi’s big green from the Frankfurt Motor is undoubtedly the e-Tron electric especially considering the recent about electric cars and made by Audi North President Johan de Nysschen. But another type of fuel/energy Audi drivers in Germany can now use to their four-ringed vehicles ethanol. Audi has never a particularly strong proponent of the but the A4 and A4 Avant 2.0 TFSI flexible models are not the first to get the ethanol

The flex-fuel engine is a modified of the standard 2.0 TFSI with valvelift and start-stop system and engines have the same (236.02 lb-ft between and 4,200 rpm) and horsepower outputs. A new A4 running on E85 will get 26 mpg on the European cycle, while the A4 gets just 25.5 mpg Super unleaded petro-gasoline these numbers into and 35.6 mpg (U.S.), respectively.

Germany currently has around 300 E85

Audi has added a new, economical version to its A4 model The A4 and A4 Avant 2.0 TFSI flexible can be operated on bioethanol. The fuel, E85, lowers operating and features a good CO2 balance.

The 2.0 flexible fuel engine is on the 2.0 TFSI with Audi and start-stop system. Like engine, it produces 320 Nm (236.02 of torque between 1,500 and rpm and puts out 132 kW (180 hp).

The engine is designed for operation on E85 the European mixture of 85 percent and 15 percent gasoline. E85 is currently at nearly 300 gas stations in Germany, Norway and Sweden having the network of E85 filling stations in

Today bioethanol is produced via the fermentation of energy crops as wheat, corn and sugar Thanks to the high renewable its CO2 balance in the total vehicle is as as 75 percent more favorable that of conventional petroleum-based The Volkswagen Group is actively in the research and development of new ethanol processes from crop for an even better energy in the future.

Audi takes of the higher RON 110 octane rating of to operate the engine at optimal This significantly reduces the 40 percent greater consumption by that is a consequence of the lower content of ethanol and thus the loss in range.

The advantage of the Audi concept is the engine can be operated on fuel any concentration of up to 85 percent ethanol no noticeable differences in drivability or

The flexible fuel philosophy a series of technical modifications. One of the properties of E85 is that it is highly to certain metals. The base had already been designed these properties in mind, so no to the fuel lines or seals required.

A different material was required for the valve seat rings due to the lubricating action of the ethanol. A in the fuel line reports the concentration to the engine management which adjusts injection and accordingly.

With E85, the four-cylinder unit achieves a consumption of 9.0 liters per 100 km (26.13 US in the A4 Sedan and 9.2 liters per 100 km (25.57 US in the A4 Avant. With super gasoline it records figures of 6.4 per 100 km (36.75 US mpg) in the Sedan and 6.6 per 100 km (35.64 US mpg) in the Avant. taxes on ethanol are significantly than on fossil fuels, its use reduces operating costs.

The Audi A4 and the A4 Avant 2.0 TFSI fuel offer the sporty enjoyment that characterizes The sedan accelerates from to highway speed in 7.9 seconds on its way to a top of 236 km/h (146.64 mph); for the these figures are 8.1 seconds and 228 (141.67 mph).
