An aerospace engineer and a team of inventors have used technology inspired by Formula One cars doing speeds in excess of 200mph to make a new gadget which helps keep the cost of fuel down. The GoFar gives live real-time feedback to drivers with an LED light display on the dashboard, glowing red or blue to tell drivers when they are driving safely and more efficiently, as used by Formula One teams.
It also uses a complex series of algorithms and 3D rocket-tracking to calculate the energy used and wasted when braking and accelerating, before notifying the driver on their fuel efficiency. The 'Ray' device, which costs £95 to pre-order, connects to an app which shows drivers exactly how economically they drive and their cost per trip. SEE OUR COPY FOR DETAILS.
