This would mean tuning by aftermarket tuners would reap similar figures. Most stock engines (from experience with Mitsubishi Evos, Subaru STis, Nissan Silvias) can output upto 350bhp reliably. This is done by bolt-on items and an ECU retune to make higher boost (typically abt 1bar). It would be interesting to see what mechanical changes will be made to this higher performance Evoque, cos if its just a retune, the 'lower performance' Evoques would still be able to replicate it through the aftermarket route.
From what I've read so far LR will be using the Ford Focus RS engine (which would be really sweet imho). I'm fairly sure if they use the Si4 engine there will some other internal hardware changes besides the turbo alone to support the power because it seems nobody is making big power from the Si4 yet.
Some engines are down-tuned from factory so a re-map is all it needs. For eg on my N54 135i I gained about 45kw from only a tune. Full-bolt ons (fmic+exhaust+intake) only gave me an extra 15kw or so and that's with the tune. On a stock vehicle it would be less. Every engine is different though so I'm not sure if the power difference alone will come from an upgraded turbo on the Si4, or it may need some supporting mods to support the new power.
I'm not fully aware of the differences between the TD4 and SD4 but they appear to be the same as well, although I'm sure there are a few limitations of the TD4. I only say this because I saw another thread from a tuner for the TD4 and it made slightly less power than the SD4 to keep it safe and retain a smooth factory map. In Australia, the small price difference makes the SD4 the better option as opposed to putting a piggyback on the TD4 and risk voiding the warranty.

Re Petrol vs Diesel, make no mistake it's VERY EASY to halve the mpg on the petrol as well, but I find steady cruising on the motorway at 80mph - 85mph (our speed limit's a little higher over here and I tend to a speed a little ) and gradual acceleration in town as well as motorway actually delivers pretty decent consumption figures. But any rapid acceleration kills the consumption figures.
I'm actually now fairly convinced if you stick to a very steady 60mph - 70mph on the motorway you should get to LR's claimed consumption (Petrol anyway)
That's fairly good consumption. With all that torque it would be hard to not want to put your foot down on the highway from time to time though

At sixty going out I achieved 41.5 mpg with a very calm right foot and driving more normally coming back and doing no more than 70 the return was 36.5 mpg. I think I'll give up trying to drive economically and just enjoy!
Great economy. Agreed it's best just to forget economy and enjoy the car
