Complete and utter bollocks ! The object is to get the vehicle to move and this is achieved by traction on wheels which are appropriate. Nissan have developed their own system which utilises technology to ensure that wheel spin is controlled. It is extremely effective and is an excellent safety measure when driving on ice and snow.Originally Posted by Mr Earl
The suggestion that all four wheels should turn at the same speed at all times is ludicrous.
Daihatsu used locks to convert two wheel drive into four wheel drive and this is their sole purpose.
I have driven Mitsubishi, Isuzu, Toyota, Daihatsu, Ford, and Subaru four wheel drive vehicles. I have also driven Land Rovers and Range Rovers, the older models always having performed better than the more recent ones.
