What speed to you cruise at in 6th to get good mpg?

Featured Replies

Emissions I think. They changed at the same time as the BLT came in.

 

Well... put it this way. My car was standard with a book top speed of 128mph but I had 138mph (gps) out of it once.

 

I didn't run out of revs but ran our of power to overcome the wind speed etc. and rev any more.

Yep that make sense.

 

I've had 130 out of mine but It didn't feel like it was going to give much more. (obviously not on a public highway)

...about an extra 25 kilos, I think. :)

 

and not that much different to 5th gear on a 5 speed derv. :)

Unless it's the Autobahn on an unrestricted section with clear traffic.

 

Ours would do no more than an indicated 130mph if it was loaded up. Foot flat to the floor with 4 adults and luggage and it just sat at 130mph no more no less.

I drove from Leeds to jct 29 m1 around 50miles and achieved 80mpg. I drove between 50-60 all the way.

Totally standard engine.

I'd humbly suggest that your real mpg was less than that as I drive that section of the M1 regularly, don't get fooled by the OBC, the only true way to ascertain your mpg is brim it when refueling, zero your odometer, then when it's time to refuel again, brim it and check the odometer for miles travelled. Easy calculation to work out your mpg

My old cop car used to show 30ish mpg on the OBC, but as it was a T5 estate, blinding up and down the m1 and A/B roads, the real figure was very low 20's, so sti es even teens.....

I think the late mk4 ibizas with factory 17s like mine have even longer ratio box, roughly 1000rpm to 30ish mph

I know cupras have a short ratio box to allow them to do 60mph in 2nd gear as people complain there poor for economy

Mine is best between 60mph and 65mph it seems, will average about 58mpg on a drive if i do that. 

**** all speed in 6th in my Insignifica; it **** it's release bearing, which caused the friction plate to **** itself, which caused the DMF to totally **** itself.

So my updated answer is, 0 mph if your 25000 mile 22mth old car is as reliable as mine....

I'm a Garage Equipment Engineer who works for a company that looks after quite a few Vauxhall garages. The amount of cars i've seen having clutch/gearbox work whilst i've been working at there sites. It doesn't surprise me at all i'm afraid chap.

I use 6th all the time. Normally from 50 plus but depending on the road can be down to 40. You can drive in 6th with no throttle at 30mph, but I don't think it's recommended. I was surprised when test driving the car, after 9 years of only having 4 gears, I changed though the gears into 6th without thinking.

 

I wonder if there is a similar thread on the MkII forum, "When do you use 7th?"?

Harry it was in 6th

You are right mate, 100%. although I've not seen any fluctuations to indicate a false reading.

from short town journeys I did 85miles from £10 which corresponded to my mpg reading which would also give me confidence.

I have received readings of 70mpg without to much effort to using similar driving.

When I get chance I'll use your method and try and get a thread up on here so everyone can see how far off it was

Chap theirs no way your getting 80 mpg. If your getting anything north of 60mpg your doing well.

I think the late mk4 ibizas with factory 17s like mine have even longer ratio box, roughly 1000rpm to 30ish mph

I know cupras have a short ratio box to allow them to do 60mph in 2nd gear as people complain there poor for economy

 

This is with 16" wheels and the ratio in 6th is even longer than you suggest.

 

Indicated speed of 120mph and you can see the rev gauge somewhere around 3250rpm maybe just under:

And before anyone flames it was on a clear, bright and unrestricted stretch of Autobahn.

 

This was also the same trip where this happened with revs at about 4000rpm:

I'm not surprised, really.

I wouldn't mind but having mastered police advanced driving techniques, I never ride the clutch pedal, never labour the engine in any gear or thrash it to within an inch of its life either.

To add insult to injury, they cracked the engine cover and failed to provide me with any paperwork to cover the work done what so ever.

Cheeky ******s the. Sent me an email hoping that I had a good experience with them; needless to say my email was succinct and abrasive, causing the service manager to ring me his morning.....

I still can't see that anyone can be driving a vRS and claim 80mpg, total bollycocks in my opinion. Seeing as even an Audi A2tdi couldn't manage that, with its aluminium construction, highly evolved aero dynamics etc I somehow don't see a Fabia managing anywhere near it

Wikipedia shows;

It was the first five-door vehicle on sale in Europe with an average fuel consumption less than 3 litres per 100 kilometres (94.2 mpg-imp; 78.4 mpg-US), although these figures only applied to the special "3L" version with a diesel engine, automatic gearbox, stop-start system, less power and narrower tyres. Due to its construction, the average A2 weighs less than 1,000 kilograms

And goes on;

The Audi A2 1.2 TDI had the lowest drag coefficient of any car in the world at the time of its launch.[20] It was also one of the most economical and least polluting, only emitting 81 g/km (German emission standard D4) to 86 g/km (D3 emission standard) CO2 emissions. The Audi A2 3L reuses the engine and special gearbox developed for the equally efficient Volkswagen Lupo 1.2 TDI 3L.

Two versions of the car were available in Germany during its production run. The D4 version, which used only 3 l/100 km (94 mpg-imp; 78 mpg-US), was "standard." It had no power steering, climate control or other extras, with the only optional extra being body coloured door handles and wing mirrors. There were no optional extras because optional equipment adds weight and loses economy[clarification needed]. It had a fixed rear seat cushion. The tested fuel economy was 2.88 l/100 km.

The second version, which was at least available in Germany, was a D3 version which was still capable of 3.0 l/100 km. This version had options for climate control, a winter pack, and a comfort pack, but was not available in all markets. Ordering these packs ensured power steeering or spot lamps as part of a package. The OSS system was not available at all on the 3L.

Both versions had thinner glass, lighter seats,[21] and 14" Magnesium alloy wheels. The standard tyre fitment was 145/80 R14 T76 Bridgestone Ecopias or Continental Winter Tyres using very flat wheel covers to minimize turbulence. The engine block was also made from a light alloy, so even though it was a diesel, it weighed just 100 kg (220 lb).

The rear spoiler was reshaped, moved and extended through wind tunnel testing, and additional underbody panels were added to minimize drag to achieve a 0.25 cd figure.[22] The car had an automated manual transmission with a Tiptronic mode on the selector. The car also had an ECO mode. When engaged it limited the power to 41 bhp (31 kW; 42 PS) (excluding kick down) and programmed the transmission to change up at the most economical point. ECO mode also activated the start/stop function, a feature that was new to European cars at the time.[23] In ECO mode, the clutch was disengaged when the accelerator pedal was released for maximum economy, so the car freewheels as much as possible, with the clutch re-engaging as soon as the accelerator pedal or brake pedal is touched. The 3L also has only 4 wheel bolts and finned alloy brake drums at the rear, along with many aluminum suspension components.[24] An internal presentation from Audi appears to indicate that the complete shell of a 3L A2 weighs around 15 kg (33 lb) less than that of a "normal" A2. The 3L has been noted on the Autobahn under non-scientific conditions to be faster at top speed than the standard A2, mainly as a result of the extremely long 5th gear ratio and the excellent aerodynamics.[citation needed]

In light of the above, I really don't see how a heavy-ish, blunt-shaped, standard construction car like the Fabia could be anywhere near the A2 3l on economy?

Please feel free to shoot me down....

I once had 73.5mpg (calculated) out of my Cordoba.

 

It was all driving on open country roads.

 

I was driving for economy and was doing things like using a lower gear up hills and using wide open throttle to get up to speed then easing off and changing up coming down the hill to gain speed and ensure the engine used no fuel on these parts. Planning ahead etc.

 

The Cordoba does have a slightly lower drag coefficient than a Fabia though too.

 

I think with a bit more perfecting of my techniques I could have got more.

 

Don't forget that some people can get stupid high figures from cars called hypermiling.

 

This is the first example I've come across with a google search:

 

http://autos.yahoo.com/blogs/motoramic/hypermilers-scoff-vw-passat-going-1-626-miles-204639036.html

 

84.1 US MPG = 100.99 UK MPG from a VW Passat TDI!

 

Phil

Too much cheese being eaten I think...

No mention made of the tyres probably being inflated to 50-60psi, drive belts being removed etc (all of which manufacturers are allowed to do in official consumption tests, by the way) etc etc etc.

I have friends in the Netherlands, Europe's flattest road network on average, that struggle to get that figure even when driving on their motorways/dual carriageways in the middle of the night, but hey, if people really want to tell themselves their vRS does 80+mpg then who am I to dissuade the poor deluded souls.

Just reaching for my antediluvian 80's mobile phone to call for the guys with the rubber ambulance as I've just discovered my Insignifica does 92mpg.....

Regardless the VRS isn't the car to have if your chasing MPG figures imo.

 

It's a great balance between speed/power and economy but if you want economy get a Prius or a bike. I obviously am not recommending anybody get a Prius i'm not that mean.

Couldn't agree more, although a chap I know had the Honda equivalent, best he ever managed was just over 75mpg, but people forget they are a smallish petrol engine lugging around a battery pack most of the time...

Prius isn't any use at all for mpg on a long run down the motorway

  • Author

Prius is only good when you're rolling down hill and it's running on battery power lol

Prius isn't any use at all for mpg on a long run down the motorway

 

Correct. I'd like to see a prius do over 50mpg on a fast Autobahn run!

 

Great round town though in start/stop all the time.

 

Recently drove a Yaris hybrid and really enjoyed the experience. But I'd never buy one!

 

Phil

Prius sucks the battery is reported to last around 20mins in stop start traffic, then it's struggling 50mpg. A blue motion polo would be superior for sure.

And to those who seem to have issues with the figures I reported and clearly struggle to decipher basic English; I'm a kind guy so I'll rephrase it :)

My on board computer gave me a reading of 80.1mpg but as discussed earlier it isn't 100% accurate so a calculation would be something I'd be willing to put my name to (assuming I'm getting the fuel I pay for).

Don't shoot the messenger :)

For the record £20 gets 14.81l (3.33 uk gallons to 2d.p) @ £1.35 per litre and I covered 170 miles (short journeys round town)

This is 51.2mpg. This is fact.

I think 60mpg is definitely possible but I do agree surely that's got be the limit of these engines. After all at the aforementioned fuel cost that's 100miles to £10 which I would be extremely happy with :D

HTH.

highest i have achieved is 64mpg on an eco run from Doncaster to Hull. 

The fabia is good on fuel, but not mind blowing. 

 

 

Im happy with 55mpg as an average, given the performance.

Interesting discussion as I've noticed the same with my Octavia (haven;t got sixth on the Fabia so can;t comment on that).  Better MPG (by some margin) in sixth at around 80 - 85 mph cruise than in sixth at 70mph.  I can only assume it is something to do with the the tipping point at which the turbo improves economy as opposed to acting as a blockage in the exhaust system...
