The other economy driver is a
480kg reduction in kerb weight
compared with the outgoing
model. It also helps that the
Discovery’s frontal area is
reduced and the aerodynamic
drag coefficient is just 0.33,
which is impressively low for a
full-size SUV.
The new Discovery’s 20%
weight saving is the result of
Land Rover’s decision to ditch
the tough but heavy steel
ladder chassis of previous
models in favour of a riveted
and bonded aluminium
monocoque shell, widely
adopted across the rest of the
Jaguar and Land Rover ranges.
