Real world mpg

(13-12-2011 03:38pm)berlin2011 Wrote:  Si4 update - 50km run to home last night 9.7l/100km (29mpg). Same run to office this AM 9.0l/100km (31.4mpg). The 50km about 60% motorway and 40% urban.

I seem to be getting the hang of getting a little more mpg out of this thing - still not LR's claimed figures but getting to within 10% of the claimed combined cycle.

That's interesting, you seem to have got a fair bit closer to the LR petrol MPG estimates than a few of the diesel guys have gotten to theirs. Maybe all the diesel drivers are heavier footed and petrol drivers are lighter due to fuel consumption ...

Same drive as before (50km) this evening got 30.8mpg - I've now down just under 1,450km (±900 miles). If it stays in this region I'll actually be fine with the consumption.

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)

This afternoon I did a shortish journey to Costco of approx 15 miles each way. 12 or 13 miles on the motorway and a mile either end on urban roads. 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!

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.

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

Great economy. Agreed it's best just to forget economy and enjoy the car

eD4- figures ? anyone ?

I have a heavy right foot and I broke out the Champagne this evening to celebrate mine creeping above 20mpg for the first time.

My real mpg (not done by trip) has moved from 29 (337miles) to 32.7 (303 miles), last trip suggested 34.3mpg, generally driving technique has got worse as getting familiar! so hope its bedding in a bit!

both figures using Sainsbury diesel, next batch is 75% Esso.

Also found out not to try rounding up tank to nearest pound... stop when it clicks out, as managed to cover my shoes in diesel...yuk! and give myself a cleaning job on car and shoes!

That's way good. I did a 20mile drive yesterday. I'd say 15 -16miles motorway. And got 34/35mpg. Cruising most the journey at 70/75

Hopefully I can get better performance but I will be heavy footed as well

what are people able to achieve with a TD ?, in theory the mpg should be better, and certainly better in manual than Auto. It is a concern if the actual figures are so far from the advertised. Its fair to say we can't expect the best mpg in the world, but lets face it the Evoque is not going to go like a sports a car, its not about that, but hopefully it will return slightly better mpg than something with twice the power !
