If you're trying to save fuel, keep in mind that the shortest route offered by a vehicle's navigation system isn't always the most fuel-efficient route. Factor in traffic jams during peak commute hours, and you could burn a lot more fuel in addition to time. But Hyundai says its navigation system's new "green routing" feature will offer drivers definitive fuel-saving directions based on Navteq's digital map and traffic data.
Announced at the 2011 International Motor Show in Geneva, the new navigation option uses details in Navteq's digital maps, such as hills, road geometry, and driving terrain, to calculate the path that will use the least fuel. The routes also take into consideration predicted traffic to avoid jams using data from Navteq Traffic Patterns. If the green-routing feature thinks you'll run into gridlock during your commute, it will find a route with better traffic flow.
According to a Navteq statement, taking the calculated green route can save about 6 percent or more compared with the traditional fastest and shortest route (which is still available to the driver).
The new feature will most likely be introduced in European vehicles before being added as a feature of Hyundai's upcoming. Last year Ford introduced a fuel-saving Eco-Route feature that also takes traffic flow into account.
