Land Rover will soon be hogging headlines for its new fuel-saving stop-start technology. The technology has been created jointly by an in-house engineering team and two major component suppliers.

The innovation assumes significance as becomes the first result of the Tata Group-owned automaker’s 800 million Pounds investment over five years in new environmental technology.

The new fuel-saving stop-start technology is expected to be incorporated in the manual diesel Freelander models, starting next May. Developed by the automaker’s engineering centre at Gaydon in Warwickshire, while being provided the engine management by Bosch, the new technology has an uprated starter motor, thanks to Denso. The company has said that the system will be available on all manual versions of the 2.2 litre diesel TD4 model of the Freelander.

Company officials have said that it would succeed in cutting CO2 emissions and at the same time focusing much on quality and driving comfort. The stop-start technology may be seen as a first step in Land Rover’s green technology road map. The car maker is expected to roll out a diesel hybrid christened Landie, capable of 60mpg and with emissions below 120g/km, later on.

Elaboarting on the positives of the new green technology, auto industry sorces said that stop-start on its own reduces CO2 emissions by 8 per cent, taking the Freelander from 194g/km to 179g/km. A notable fact is that on a typical 40-minute journey, a vehicle’s engine is only needed for about 19 minutes, they said. Tipped to be the world’s first intelligent stop-start option in a SUV, it is believed that fuel consumption can be improved by 12 per cent.

The new technology is expected to bring along features such as sensors which will automatically restart the engine if the cabin starts to get too cold or too hot so that the air conditioning operates. It will also work if the windows start to mist up. The engine would restart automatically if the Freelander starts to roll more than six feet, a preview report of the new technology said.
