The rolling resistance of the tyres has a big influence on a vehicle’s consumption. For this reason, Mercedes-Benz deploys tyres with low rolling resistance in the new A-Class as well. They are formed in a different way and use a different rubber blend to conventional tyres. With unchanged handling and braking characteristics, the rolling resistance can be markedly reduced with them.
The ECO start/stop function reduces fuel consumption and emissions by switching off the engine automatically when the car comes to a stop (e.g. in traffic jams or at traffic lights). If a vehicle is equipped with the ECO start/stop function, a starter/generator is installed in place of the starter. Intelligent control electronics allow the starter/generator to supply the electrical energy for the vehicle’s electrical system and, in starter mode, the torque required to start the engine.
So that the driver is able to check and, if necessary, adapt to a more efficient driving style, the ECO display provides feedback on how economical his handling of the vehicle is, and helps implement a consumption-optimised driving style for the given and chosen framework conditions.
