fuel efficiency

You can read as much as you want about driving methods that will result in better fuel efficiency, but putting them into practice is next to impossible without proper feedback. The ScanGauge II effectively solves that problem by giving the driver real-time data as well as post-trip data, letting the driver adjust his or her driving methods on the fly to maximize fuel efficiency.

The ScanGauge II is an energy monitoring device that will mount on the dashboard of most vehicles. As you can see in the picture (which must be in a car involved in a high speed chase), the ScanGauge II shows you your fuel economy (MPG), vehicle speed, engine speed (RPM) and battery voltage.

The latest concept incarnation of Volkswagen's Golf TDI achieves an impressive 62 mpg. In addition, carbon dioxide emissions are limited to just 99 g/km, less than a Toyota Prius. The vehicle will likely be sold in the UK starting in the middle of 2009. This level of efficiency is achieved with a 1.6-liter TDI diesel engine.

The engine generates 105 horsepower and brings the car from 0 to 60 in 11 seconds. In addition to the smaller engine, mileage in this model has been increased with changes to the transmission, low rolling resistance tires, and improved aerodynamics.
