The revised powerplants are partly a result of Land Rover's joint development programme with Jaguar, and are intended to give a nod to green concerns as well as overall performance.
The Range Rover Sport will still have a choice of 3 engines, but the 'baby' 2.7-litre V6 is now up to 3.0 litres (it's actually related to the new engine in the Jag XF) with a consequent power-hike of nearly 30 per cent. The 3.6-litre TDV8 is unchanged, while the range-topping supercharged version is up to 5.0 litres (that engine too being shared with Jaguar). It uses variable camshaft timing, a new direct-injection system and a revised twin-vortex supercharger to impressive effect, with 29 per cent more power and 12 per cent more torque along with small improvements in both fuel economy and CO2 emissions.
The model range shrinks from seven models to four, with two main trim levels of SE and HSE instead of the previous four. SE becomes the most basic trim (with the 3.0-litre unit only), but even then the Sport is pretty plush, with leather, 19ins alloys and enough multimedia bits to start charging people for entry.
HSE spec adds more decadence, and larger-engined models bring further refinements, including a new version of Land Rover's 'Adaptive Dynamics' system and clever adaptive cruise control. The 5.0-litre flagship even gets a 'bling' chrome tailpipe finisher, allowing lesser cars to see their lowly reflection amongst your refined fumes.
In its latest 'Discovery 4' incarnation, the Disco also gets the new 3.0-litre TDV6 seen in the Range Rover, in addition to the existing 2.7-litre variant for the GS base model. Prices continue to rise across the range, with the range-topping HSE up £2000 to £47,695, but new interiors and improved standard equipment across the range as well as the new engine account for at least some of this optimistic packaging shift.
Both revised Landies go on sale on 1st September this year.
