The unique system, developed in conjunction with NASA, works via a discreet unit located in the front valance that projects an enhanced magnetic beam 20 metres in front of the BMW. Once a suitable target car is located and the BMW is magnetically locked on behind it, the driver is then able to take his foot off the accelerator, turn off the engine and let the car in front do all the work. The towing car will not notice any change in manoeuvrability.
The BMW driver can unhook from the towing car at any time by depressing the clutch pedal to start the vehicle. This is the same method used to operate the existing Start Stop system. Drivers of automatic transmission BMWs need only move the lever into the ‘D’ position to continue on their way.
Early research indicates that MTT could save as much as 30 per cent in fuel consumption and CO2 emissions. Gurus from BMW’s in-house driving etiquette guide suggest flashing the car in front and giving a friendly hand gesture to thank them for the free ride.
