(www.autoinsidernews.com) вЂ" Audi is expanding the range of its two highest-volume models, delivering four new, more efficient models вЂ" the A3, A3 Sportback 1.9 TDI e and A4 2.0 TFSI e (sedan or Avant). The advanced engines employ direct fuel injection for both the petrol and diesel engines.
All four new models feature a gearshift indicator, located in the instrument cluster, to indicate when drivers should upshift. The system analyzes current engine load and speed to suggest the most efficient shift points. The new gearshift indicator provides valuable information for a consumption-orientated driving style, reports Trend.
To improve efficiency, the A3 features higher transmission ratios for 3rd and 5th gears, while the Audi A4 models get a manual gearbox with an additional, high-ratio 6th gear. Other modifications to improve efficiency include: various weight reduction measures, low-rolling-resistance tires, and aerodynamic improvements. The engine electronics have also been tuned to reduce fuel consumption.
Audi is also relaunching its efficiency training courses to train drivers how to drive more economically.
