Basically instead of VW/Porsche/Audi's 1 car fight all sector strategy.. they split it in both.. which I think is a better idea because it can cut weight.
By how much? ...do we know the weight of the RR Sport? ... compared to the regular RR and to the LR3. Are we sure the off-roading hardware weighs less on the RRS or is it the shorter wheelbase and length that make it lighter?
