Real World MPG - post your figures

[skidpan]

standart rolling resistance tires.

LEON is rougly 70KG lighter than the equilavent Golf. Ever wonder why they have the same performance and consumption when Golf is heavier? It comes with low rolling resistance tires from factory which reduce overall consumption by 3-4% ).

Well my Leon has the same Michelin Energy Low Rolling Resistance Tyres as fitted to the Golf.

Figures taken from brochures downloaded when I bought my car in June.
Leon 1.2 TSI DSG 1222 kg Combined mpg 58.9
Golf 1.2 TSI DSG 1229 kg Combined mpg 56.5

So the Golf is 7 kg heavier (wow) but is worse on mpg. Suggest you check your facts.

But the simple fact is 99.9% of people drive in a perfectly normal manner. Yes they moan about not being able to achieve the official mpg figures but the simple fact is they have no idea how they are obtained and how meaningless they are in the real world. Driving in a manner that impedes other road users in order to improve your mpg is not safe, it can lead to the drivers following getting increasingly frustrated if they cannot overtake and can lead to accidents.

This thread was originally about what Leon TSI owners are getting in normal everyday driving (Quote from JackReacher's original post "normal driving conditions"), lets keep it like. If you want to start a new thread about economy driving techniques go ahead.

In reply to weatherlights last post (as his quote is not showing in my post)


I'm not saying its not possible, but I can't get near the official mpg for my Leon tdi & I did try
It doesn't really bother me as I take the official figures as a Disney tail
But I have yet to meet anyone in the flesh who can get official mpg from their cars
As you mentioned mk7 golf there are sevral posts including one running to 30 pages regarding getting official mpg and not one of them can, one poor chap is changing his mk7 golf because of it as even the dealer could not get close to official mpg and you can bet they were trying bloody hard

Back to the ops post if your doing that sort of mileage, I would personally go for the bigger engine diesel model, less hard work if you doing a lot ofmiles and pprobably slightly better fuel economy than the small petrol but that's subjective

When the real-world MPG figures for the SC start to come in, it will be interesting to see how they compare with the five-door.

SEAT quotes almost identical combined urban/rural figures for the two versions (using the same engines), but the urban figures for the SC are slightly better for some engines (for example, the 1.2TSi and the DSG version of the 150PS TDi) than the five-door, and the extra-urban are slightly worse.

But it's the other way around for the non-DSG 1.8TSi!

The figures quoted for the 1.4 TSi and the non-DSG 1.6 TDi are identical for both versions.

Logically, you would expect the SC to be slightly better than the five-door because it has a sleeker shape, is slightly lighter and avoids the air resistance of a pair of door handles. In addition, the FR versions ride 13mm lower.

Like I say, it will be interesting to see when the real-world figures come in.

Hmm you're right it is only 7 kg lighter. Leon brouchure in my hands says 1160, for Golf it is 1230. Thing is they made a brouchure without the driver for Leon but with the driver for Golf here. Both brouchures list fuel economy as 4.8L /100km combined. Here Leon does not come with low rolling resistance tire as well (mine came with conti premium contact 5).

It is strange that 2 almost identical cars with only 7 kg difference and same tire type has nearly %4 difference in MPG. Maybe incorrect brouchures, differing from one country to another. Maybe Leon's drag coefficient and frontal area numbers are smaller than Golf, anyone have numbers? Perhaps Leon's engine used at test had great break-in, would engine break-in result in a +- %2 change?

Still there is a fact for all newer vehicles including Leon, that the companies use a technique called cycle-beating. Since taxes are based on CO2 emissions in some countries and low fuel consumption is an important trait, most of the companies match the gear ratios with the engine output curves such that they consume the least at a cycle test, but mostly more in normal driving (faster, higher or lower rev driving). It is harder to reach official mpg compared to 10 years ago, still possible though.

New Golf or old Golf? There's no way the new Golf is 70 kilos heavier.

Correct.

But if you look in post #21 you will see where included the correct figures from the Mk7 Golf and Mk3 Leon brochures.

In post #24 weatherlight corrected his original error.

People say EPA values (U.S.A tests with faster acceleration and more stops) are closer to normal driving conditions. Although anything below 2L is out of the question there, I found GTI's EPA highway rating, close to Europe's combined ratings. So I'm guessing combined values can be seen at extra urban and around 3/4 of it for city.

6.2L (45.5mpg) average for 400km city driving, including some very heavy congestion (worse yet some were uphill stop-go traffic) and higher speed multi lane roads. Including a few sport mode moments with up to 6K revving, although I did my best to eco drive the rest. What really kills mpg in 1.2 is congestion at hills, instant consumption does not drop below 20L /100km

Perhaps a TDI can handle up-hill accelerations better than a TSI. I found a comparison of the engines. When pushed hard TSI returns like 52% where TDI returns 56% of MPG in Fabia. Any TDI drivers out there that can tell their MPG in eco as well as spirited driving?

I got my 150FR in Red and 2 days later set off on a European road trip totaling just over 2500 miles, which included city driving and sustained high speeds on the German Autobahns. My average for the whole trip was an epic 59.3.

Not a bad average on a brand new engine. Car was superb and I can honestly say its the est car I have ever had.

 

[CJRamze]

Anyone driving 60mph mostly motorway?
I do about 40 miles to work and 40 miles back an I'd say 38 of those miles are at 60mph and I simply dont budge from there unless I have to.

Remapped and De-DPF'd MK2 Leon 2.0TDI 170 is getting about 67-68mpg at the moment
I dont know why but I was hoping for more economy out of the MK3.

 

[weatherlight]

Cars with some mileage (20K+) may have the engine and drive-train components really smoothened out comapred with new ones. Anyone with 10K+ mileage on their mk3s? If yes can you please compare the FE of your car back at 1-2K and now?

FR TDI 184 SC

Done 1300 miles approx

Computer based results:-

42 mile commute each way 3 times per week M1 with lots of average 50mph. cameras and the rest A roads. The rest of the time it's normal A and B stuff in a major city.

Average since new 55MPG.

Best journey average doing route above 70.3MPG

Normal journey doing route above high 50's MPG.

Climate is allways set to 21C. if relevant.

I really must make a consious effort to get my MPG lower...It's an FR for gods sake

Yesterday I went to the airport. 4.8L /100km average (59 mpg) on a 69 km road from home parking lot to the airports and back. Since it was a trip and back, no elevation differences and no wind at all either at my home or the airport.

With a total of 6 stops and parking manuevers, computer says average speed at 67km/h where I mostly went with 80-100 on 63km highway. My tank was more than half and I was taking my wife + luggage on the way there (60kg used %1.2 more fuel estimated). Tire pressures were 34 psi front, 33 rear. It was dark and low beam lights were on the whole time, AC was off, fan set at 23 degrees C.

Since I have a dsg and no eco mode, I cant coast and I did not stuck behind another vehicle to cut off drag. I'm around %4 off from official values, engine at 2600km (6km city, 63km highway driving + 60kg extra load on one way and lights should have used about 4.6L/100km). Road had long, steep hills as well, raising instant consumption to 9-10L/100km from time to time. Perhaps 1.4TSI consumes less while climbing hills, compared to 1.2

Well I finally got to test drive a 1.4 at the weekend, it was the engine I was most interested in having driven the 1.2 and 2.0 Tdi. In both of those, on the test drive we got about 46-48mpg.

It was only a brief drive, approx 5 miles from cold and the average mpg of the 1.4 showed 32 mpg, driven mostly sensible with a couple of spurts of power to see how it performed. I really liked the engine, quiet, refined with enough power but was left disappointed with the mpg having read reports of late 40's and early 50's being possible. I know it was a short test drive but I would still have expected early 40's. The car will be doing 20k miles per year, and as much as I like the 1.4 I think I will have to look at the 1.6TDI, same engine as our current A1 but nowhere near as nice as the 1.4 TSI

 

[CJRamze]

Don't be too disheartened Jack.
I think the main problem is getting them up to temprature. When mine is cold I get 40ish even driving super ECO (MK2 Leon Now) but once the engine is up to temprature and going strong I see 60+ sometimes 65!

5 miles is way too short a distance to get any idea of fuel consumption. Cold engine and probable stop/start traffic will not show the real figures possible. My 1.4 shows over 50 mpg since new on the computer now (2300 miles). No special economy techniques, just normal driving. Computer is a bit out, calculations show 46.5 mpg is closer to the truth. Well happy.

I've just taken delivery of my 1.4 FR SC and I'm just back from my first real drive - 135 miles on a mixture of motorway, windy country roads and a little bit through a town where I even found myself approaching (to my horror) a one-way cobblestone road. Needless to say my speed over the cobblestones was extremely slow (much to the annoyance of the cars behind me).

The whole trip was done in Sport mode (I didn't select this - I just assumed that the car was set to Normal by default and didn't bother checking until near the end of the trip!).

Door-to-door was exactly 50mpg - as in 50.0

My previous car averaged 33.5, so I'm very happy with 50 on this first decent drive

 

[Shiners]

Filled up today (brimmed) - 32.5lt used and 393 miles covered. Most journeys consisted of a 29m drive from home to work. This consists of 2m of narrow hilly road; 6m of flat but poorly surfaced A class road and 20m of well surfaced Undulating Trunk road and a mile of town roads. Had one active regen (DPF) at the end of one journey. My FR 184 has covered just under 600m and I work the gearbox to try and keep the engine speed around the 2k mark with ocassional bursts up to 3k. Having read all the hype about the claimed MPG figures and taken them with a large pinch of salt, I'm encouraged with 54.96mpg at this stage...

 

[Mac]

fuel consumption is shi7e on my car 2010 CR 170 remapped to 217 by revo, dsg gearbox,
i get 43mpg or 6.7 l/100km which is a lot
even when i drive it gently it wont give better fuel consumption

Seat Leon 5DR CR 1.6TDI SE Copa poor MPG

After 1 week of soft driving the MPG figure was 43 (measured at the pump), having sold my 1.9 GTDI 5Dr 130BHP Golf that averaged 50MPG around town and up to 65MPG on a long run (driven hard) the Leon is very disappointing.

Its so bad could it be there is something wrong with my it?

The Leon has just clocked 18000 miles, so its quite new and I guess I was expecting around 60MPG+ having driven it very gently.

It seems now I have the worst of both worlds, low MPG and low performance.

Does anyone have something similar and willing to share their MPG before I take it back to the dealer.
