Audi to Launch Next Gen Diesel and Hybrid Engines

Alternative fuels

Alternative fuel types are gaining in importance around the world. Natural gas, for example, is being used increasingly in a number of countries as a more cost-effective energy source with a lower CO2 content. Here, Audi has devised a concept for using CNG (Compressed Natural Gas). It is based on the TFSI engine and retains such strengths as its mighty pulling power even when running in natural-gas mode. The reduction in CO2 emissions of up to 20 percent in CNG mode can therefore be enjoyed without having to compromise on driving pleasure in any way. Moreover, the ingenious packaging still allows full use to be made of the luggage compartment and the vehicle's versatility despite the addition of the natural gas tank.

The same applies to the ethanol drive system from Audi. It is designed to run on fuel consisting of up to 85 percent ethanol – again without any loss of dynamism or sportiness. And yet, the CO2 output of such a drive system is around 75 percent lower when running on second-generation bioethanol than when it is burning conventional petroleum-based fuel.
The driver’s crucial influence

Audi will continue to demonstrate its renowned “Vorsprung durch Technik” to the customer with all manner of technical solutions. It goes without saying, however, that it is the drivers themselves who bear a large part of the responsibility for driving in a manner that burns less fuel. The individual driving style can influence fuel consumption and, as a result, emissions by as much as 30 percent – without any great difference in speed or dynamism. Driver awareness and attentiveness are the decisive factors here. Audi will additionally provide support systems that help drivers modify their driving style for optimum fuel consumption. One example of such a driver aid is the gearshift indicator that is already included as standard on the e models and the new A5 and displays the optimum gear for the current driving situation.

Extra efficiency at the push of a button

Audi has already unveiled a vehicle that gives drivers the option of selecting an especially fuel-efficient mode for certain situations at the push of a button with its Cross Coupé quattro study. In the “efficiency” mode, the engine and the gearbox mapping are switched over to a more economical operating programme, the power draw of the main consumers and comfort modules is restricted, and the cruise control system is programmed to give priority to low fuel consumption. This mode is selected intentionally by the customer and is accompanied by a slight reduction in both power and comfort. Apart from this, as the navigation system's road data becomes even more precise in future it will be used for particularly economical routing and vehicle guidance.

With the help of its clean-running diesel power units and integrated efficiency strategy, Audi is set to hone the sporty and elegant character, the sense of driving pleasure and the high-class quality of its models whilst continuing to reduce their emissions.
