September 15, 2015 by Audi
•New Audi A4 family of models makes first major public appearance
•Audi e-tron quattro concept car offers outlook on the future
•Audi continues to make its TDI and TFSI more efficient
At the 2015 International Motor Show (IAA), which begins today in Frankfurt am Main, Audi is presenting many different new products. The main focus is on the new A4 model line and the near-production Audi e-tron quattro concept car – a sporty SUV with an all-electric drive. The company is also offering visitors glimpses of the future in four of the brand's focal themes – Audi Sport, quattro, Audi Technologies and Audi ultra – and is presenting the entire range of its drive system concepts.
Audi continues to make its TDI and TFSI engines more efficient with new technologies. In this way, the brand is fully exploiting the potential of conventional engines. The CO2 champions of each model series bear the supplement 'ultra'. The new Audi A4 2.0 TDI ultra is making its motor show debut at this year's IAA.
In the SUV segment, the purely electric Audi e-tron quattro concept car is celebrating its world premiere. Also to be seen at the motor show are the Audi Q7 e-tron 3.0 TDI quattro as a plug-in hybrid with up to 56 km (34.8 mi) of all-electric range and the new Audi A4 g-tron. The latter consumes less than four kilograms (8.8 lb) of natural gas per 100 km (62.1 mi) in the standardized cycle. For customers, this means extremely low fuel costs with a total driving range of up to 950 km (590.3 mi). In addition, the new Audi Q7 and the new Audi A4 offer the broadest array of assistance systems of all production automobiles. They illustrate a preliminary stage of piloted driving. Audi is promoting the development of all of these technologies with great vigor – always with the goal of uniting maximum efficiency and safety with strong performance.
The new generation Audi A4 impresses with a balanced and sporty driving experience, a large selection of infotainment solutions and highly intelligent assistance systems such as adaptive cruise control including traffic jam assist. Up to 30 optional systems assist drivers. The mid-class model also attains top figures in efficiency. The A4 Sedan is extremely aerodynamic with a best-in-class Cd figure of 0.23. Its efficient overall concept is supported by lightweight and efficient engines such as the 2.0 TDI ultra with 110 kW (150 hp). In the Sedan, this engine reduces NEDC fuel consumption to 3.7 l/100 km (63.6 US mpg) with 95 g CO2 per km (152.9 g/mi). The newly developed 2.0 TFSI ultra is the equal to its diesel counterpart in all respects. Thanks to an innovative combustion process, the 190-hp gasoline engine has a low fuel consumption of 4.8 l/100 km (49.0 US mpg). This equates to CO2 emissions of 109 g/km (175.4 g/mi).
At Audi, the mobility of the future is sporty, charged with emotion and highly efficient – the Audi e-tron quattro concept technology concept car offers an outlook on the brand's first large-scale production electric car that will arrive on the market in 2018. It is based on the second-generation modular longitudinal platform, which offers considerable degrees of freedom in configuring the drive system and package. The design of the sporty SUV is based in large part on aerodynamic requirements – with a Cd figure of 0.25, the car sets the benchmark in the SUV segment. The electric drive – with three electric motors that output up to 370 kW – follows the e-tron quattro concept. The lithium-ion battery in the car's floor enables over 500 km (310.7 mi) of driving range and thereby full everyday practicality. Innovative technical solutions in the areas of controls and infotainment also deliver a high level of convenience and user friendliness. The Audi e-tron quattro concept comes equipped with the technology for piloted driving.
The Q7 e-tron 3.0 TDI quattro is the first TDI plug-in hybrid with quattro drive from Audi. With 275 kW (373 hp) of system power, it accelerates from a standstill to 100 km/h (62.1 mph) in 6.0 seconds. Its NEDC fuel consumption is 1.7 liters of diesel fuel per 100 km (138.4 US mpg), and it can be driven up to 56 km (34.8 mi) all- electrically – quietly, powerfully and with zero local emissions.
