This is the Range Rover Sport fitted with the newish 3.6 litre V8 diesel engine.
This engine is by far the best choice for the bigger Land Rover models, so it's a slight mystery that it hasn't made it into the Discovery yet (the Range Rover Sport is much more similar under the skin to the Disco than it is to the standard Range Rover, so I'm assuming it would fit), especially given that the 4.4 litre petrol V8 seems to have been dropped as an option for the Disco, at least for the UK market.
The Range Rover Sport caused a bit of disappointment when it was launched because it didn't look as dramatic as the two-door Range Stormer concept car, but I still think it looks pretty good. I read somewhere that Land Rover might produce a de-blinged version, which would probably be even nicer.
Not keen on big SUVs in general but I usually make an exception for Land Rovers on the grounds of ability, authenticity, looks and Britishness.
