Our new 1.2 Chevy only does 36mpg :-(

[Mr_Bo11ox]

I always get 38-39 from my Rover 220

[dieselnutjob]

604 got 13mpg when I filled it up yesterday.... average is about 18mpg

Now I now i'm pretty fresh around here but i have to comment.

The dealer will find nothing wrong because there is nothing wrong. Korean cars are massively thirsty, always have been. This comes from experience of being a daewoo/chevrolet tech and then a hyundai tech. The figures are achieved in a perfect lab environment with no wind at a constant 50 in 4th. No real person will ever achieve book figures on a modern car unless you drive downhill everywhere. Thats why my brothers hyundai coupe is in the highest tax band possible and does fuck all to the gallon. Its designed for the yank market and it he sees 30 mpg its a good day. Oh and all korean cars have the mpg meter in imperial US gallons FACT.

Sorry.

 

The bigger Daewoos (Espero, Leganza, Tacuma) were always regarded by the trade as 'juicy'. As Chevrolets that we get in the UK are in effect Daewoos, should we be surprised at 36mpg for a Fiesta sized car?

I an act of self preservation the Audi Coupe's odometer and tripodometer have both decided to stop working. Before they expired, I did manage to get 24mpg out of it driving it from Leeds to Devon for a wedding in the summer but in the absence of any evidence to the contrary I can only assume that it is now miraculously getting 50+MPG easily.

 

Ignorance is bliss.

A friend of mine had a VW Golf diesel that supposeldy got 65MPG.

 

Once MPG was actually calculated, it turned out it only achieved 45MPG...diappointment all round, as it "always got 65MPG before....."

Is the Aveo known as the Sonic in the States?

 

An article on GM in yesterdays Financial Times (we get it at work) quoted an 'expert' from Edmunds.com(?) as saying its the best car in its class and GM are selling them by the boatload - outselling the Honda 'Fit' (the Jazz?), Yaris, Fiesta etc. The picture of one looked like an Aveo, but did say the Sonic was built in the US, somewhere north of Detroit.

 

The rest of the article, which was broadly favourable to GM, did mention Europe was now the main problem and GM should have been more decisive when they had a chance to sort it (I think the implication was sold it to the Russians/Chinese) in 09-10.

Very true about the motorway trip - small engines just don't like 'em!

 

 

Very true - I once drove from Sheffield to Laandaann in a Astra 1400 petrol (of the 04-10 plate generation) and it was pretty terrible on consumption, didn't bother working it out as fuel cost was on expenses, but was quite shocked at how quickly the needle went from right to left.

 

Mind you - I did cane it a bit - 'nothing drives better than a rental car' !

[Partridge]

Do you have to rev the Bristols off it to make it go anywhere?

 

I get mid 30’s to about 40 at a push from the 1.4 Polo depending on how I drive it. I mostly chug around like Richard Bucket in it though and rarely go over 2,500 revs.

[Split_Pin]

The Sonic is the US manufactured Aveo, but those are all 1.8 Autos or 1.4 Turbos.

 

I think mine is manufactured somewhere VERY far east, China springs to mind.

Wetherby to Inverness in 6 hours 30 minutes, including stops and sitting in traffic jams on the A80 for 15 minutes and 10 minutes in traffic on the A9, load up the boot with an Imp engine, race off down to Fort Bill and fill up: 37mpg in a 1300cc Cavalier. Small engine, biggish car - and it wasn't being driven gently.

I refer to my previous post about lard.....................a bet one of those new Vauxhall Adam things weighs considerably more than your Cavalier...........

[John F]

I managed 30 mpg on a trip from Duisburg to Yorkshire recently in my Discovery 300 TDi... loaded up to the gills with crates of beer and a Calibra Turbo floorpan & front subframe, generally travelling around the 70 mph mark but with occasional hoonage up to around 100 mph to make the most of being on the Autobahn

*edit* I see Colc has made the same point. SHould not have had lunch in the middle of writing that.

[M'coli]

IIRC the Cavalier's about 1050, but the point about being not-too-lardy stands despite me driving it .

[Ian Nexus]

not sure if this helps, bear in mind a US gallon is 14% smaller than UK gallon

I used to have an 05 Sportage, and that did have the MPG indicator in US gallons, but Kia reprogrammed it as a matter of course at a service after a bulletin was issued from on high. I doubt that they're still sending cars out today with the same issue.

 

Either way, ignore the mpg calculator and use the brim - brim method to calculate your fuel consumption if you want an accurate indication of what you're getting.

Im still dumbfounded by Imperial measurements when it comes to fuel.....The Year I started school in Australia..1972 – all primary schools were teaching the metric system alone. Many had been teaching both imperial and metric and later, metric alone since Australia changed to the decimal currency system in 1966. Horse racing converted in August 1972 and air temperatures were converted in September 1972

Also within a year I moved to Scotland...and the majority of my fuel filling history was Europe..NZ or here..

 

The Mercs diesel gauge likes to read how the car is positioned..all i know is its shit in a traffic jam like today but great on the highway...

Hyundai/KIA are about to have their bum's felt in the US for misrepresenting fuel economy figures.
