Vexia Econav 480 satnav
GPS for treehuggers?
Review Arguably there’s been nothing really innovative in satnav for some time. But the Econav 480 claims to be able to help you save fuel and the environment by telling you how to drive in a fuel efficient way while getting you from A to B.
The Green Economy: Vexia's Econav 480
It does this by comparing your driving with what it knows is the optimum driving practice for your vehicle. It tells you when to change gear, alerts you when your driving exhibits excessive braking and acceleration, and produces stats to show how you improve over time. The vendors reckon that using Econav can reduce your CO2 emissions by up to 30 per cent.
Keeps a record of your motoring efficiency
The Econav’s 4.3in screen is quite sharp and bright. There is an on/off button on the top edge, a micro SD card slot, mini USB connector and 3.5mm headset jack on the left edge. The windshield mount is solid and dependable. The screen is touch sensitive and a small stylus lives in a housing on the Econav’s casing. I can’t see it taking the place of a finger very often, to be honest but it is there if you want it.
A weekly view of your motoring eco stats
Setting up trips follows the usual patterns. If you know the postcode just enter it, but there’s no house number accuracy using that method. Alternatively enter a location narrowing down from what the software calls a city but which can actually be a London borough, town, or somewhere smaller. To get somewhere useful in a town you don’t know, you can opt to search for a parking location, hotel, health location, entertainment spot or other Point of Interest.
Save fuel by saving weight in your car
Go to the toilet before travelling and do not attach this numpty device to your windscreen.
id like to have a go....
how does it deal with bends and corners? does it give you a rally style apraisial of whats coming up? or will all the really twisty NSL roads that i drive on confuse it and the thing instruct me to charge down them at warp speed without slowing for the copious hairpins?!
its fun, sort of like seeing how low and long i can get my current mpg on the incar computer (4mpg - Volvo C70 T5) but I wouldnt want to pay for it!
Can't be that obvious
or you would have got it right.
Keeping pedal level does NOT necessarily mean optimum fuel efficiency. It depends on the road- hilly roads benefit from varied use of the pedal, flat roads, you can keep a constant speed with a flat pedal. Speed would be about 62mph, rather than the figures you quote. And of course, keeping the pedal in the same place whilst trying to go round a corner could be non-optimum in the bumper bending department. Since most roads in this country are not motorways, methods of improving driver efficiency are to be welcomed -for example, do you know the optimum acceleration for your particular car to get from 0 to 60mph? No? Thought not. Acceleration and deceleration are where the savings are to be made, not doing a constant speed on the motorway.
