The new flagship SUV is expected to cast a shadow similar to the current model, just with a lower roof. This should significantly reduce the frontal area and, therefore, the overall aerodynamic drag. Mass will be reduced by using a riveted aluminum chassis with the same type of construction as the Jaguar XJ. Composite materials will also play a part in the body panels. How much will these efforts save? Land Rover is apparently targeting a cut of 450 kilograms (992 pounds).
A 3.0-liter turbodiesel V6 engine that is now available in the Jaguar XF and XJ should bring CO2 emissions down from the the current 300+ grams / kilometer to under 200 g/km along with fuel economy of 33 mpg (U.S.). A diesel-hybrid is also expected in the lineup a couple of years after launch.
