    Audi, a company known for race-inspired ride and handling, is making its passenger cars more fuel-thrifty. The automaker plans to decrease fuel consumption 20 percent across the model line-up by 2012, as compared to the 2007 level.

    A new start-stop system shuts off the engine at idle to save gas and reduce CO2 emissions. The system works on manual transmission cars only: its turns off the ignition once the car has come to a stop, the gear lever is in neutral and the driver releases the clutch pedal. Depressing the clutch restarts the engine.

    The system rolls out the second quarter of 2009 in the Audi A3 TFSI with manual transmission, and in the Audi A4 and A5 with two-liter engines and manual transmissions.

    Audi’s energy consumption system uses deceleration to convert kinetic energy into electrical energy. When the car accelerates, the battery sends the temporarily stored energy back into the vehicle to relieve the alternator and save gas. The system is currently standard equipment in the A3 1.4 TFSI with manual transmission, the A4, A5 coupe and A5 cabriolet with two liter engine and manual transmission, the A6, Q5 and Q7.

    A new driver information system continuously analyzes energy consumption and gives the driver tips on saving fuel. A new gearshift indicator tells the driver when to shift for optimal fuel economy. A display identifies systems such as the air conditioner and seat heaters that require extra gas, and indicates their share in fuel consumption. Drivers who follow the guidelines can improve their car’s fuel efficiency up to 30 percent, according to the manufacturer.
