Nissan (Yokohama, Japan) has come up with a creative way of using telematics to promote efficient driving habits for early adopters of its "zero emission" electric vehicle, the Leaf. A section of the vehicle's integrated infotainment system supports a service called "Carwings," which not only tracks the energy efficiency of the user's driving style, but compares statistics with friends and neighbors using the system.
The functionality was discovered by a user on the MyNissanLeaf.com discussion forum and quickly picked up by various outlets, who recognized it at a natural extension of the Toyota Prius' dashboard mileage readout. When the Prius first launched, some drivers took great pride in achieving the highest efficiency readout among peers. Nissan has automated this process.
The Leaf is able to display how many miles the driver achieved per kilowatt of energy, as well as identical data for other users in the region. The scores are then ranked, and medals are granted depending on each driver's proficiency: bronze, silver, gold, and the coveted platinum trophy.
At this time, the medals seem to be nothing more than bragging rights. Nissan has not announced plans to reward frugal drivers with anything tangible, nor have they announced what they plan to do with these statistics.
