What mpg are modern petrols getting

i would say as others have pointed out that weight has a big part to play in this.. id say the civic i drove was much lighter than the octavia im driving.. the body and the engine block.. that was a peach of a honda engine.. they managed to decrease the weight substancially of the engine block while still managing to pump out more torque and bhp than competition for less consumption..

i always compared it to my dads 1.6 diesel octavia which i think was 105bhp - was underpowered for my liking.. the civic hit kindof a sweet spot but i do enjoy the extra 30bhp i have in the octavia now..

I had the same model civic in the 2.2 LT diesel 150 BHP , and have to say I definitely miss the extra power , but you get used to it.mpg where extremely good on that car too around 60mpg.

You're right, but my brother does

I know American cars have a bad rep but the thing is amazing. Has more extras than nearly any car I've owned, electric everything.

2012 Mondeo 2.0TDI - 48-52 mpg depending on the time of year. Higher mpg in the summer which I presume is due to less warm up time. Ranges 1,150 to 1,300 KM per 70 litre tank.

You can thank VRT for that. We end up with very basic models to keep the pre tax cost down so when VAT and then VRT is added it doesn't price us all out of the market. VRT has to be the greatest con job our government ever came up with. At the very least it should be calculated on the pre VAT price and safety equipment should be exempt from the calculation.

21.7mpg from the 325...

Good point regarding the safety equipment. But woudn't that mean that the mandatory airbags and ABS suddenly are 95% of the price?

KERSPLAT!

When people say a diesel needs to be warmed up or a petrol takes less time to warm up, what kind of distance/time are you talking?

I'm wondering if I should be avoiding a diesel.

I drive a 2011 Toyota Auris hybrid, 1.8 petrol. I have kept my own record for calculating mpg over the past two years and it averages 52mpg, not the claimed 75mpg. That’s with a good mix of driving with a light enough right foot. We also have a A6 2011 2.0tdi and that averages 40mpg, I’m sure it worsened when they fixed the vw emissions scandal thing.

Chip or map the A6. My A4 s fuel economy got 6mpg better after it was chipped

My morning commute says 6.7L/100km

I have no idea what that means in plain english or if its good in comparison to MPG.



What I really wish it told me is exactly how many litres of petrol it used for my journey.

I'm not anti diesel but the new honda diesels requiring service at 10k km is daft.. that would be nearly three services a year for me. My brother has a vw sharan and it needs a new egr and few more bits costing in excess of 2k.. admittingly they are only doing short journeys so that's probably the main problem.

new egr ? brand new car?

I thing fur this kind of discussion we need to compare apples to apples.

lets start with the same manufacturer and model
same mileage driven daily

My VW diesel requires service not as often as 10k . the older it gets the shorter is service interval


Now on topic. saw seat TSI and TDI version are in the same CO band. so probably same MPG. Autostart may save the day for city traffic.

It’s eash enough to calculate😋 trip km*0.067= L of fuel

Well, I just measured the distance and it's exactly 100.4km round trip.
6.7L it is.

Drove an a6 2014 2.0 TDI automatic to the very north coast of northern Ireland from Dublin today (and back). Most of it between 120 and 140 kmph plus traffic in Dublin and Belfast.
Average consumption was 6.2l/100kms which is about 46/47 mpg. Fairly happy with that. Long term average on the car is about 40mpg.

The sharan is at least 5 years old.. to my earlier post.. I don't think short journeys etc start to appear as issues till after year three with diesels.. my dad's Octavia had the same issue at about 5 years old. The egrs did give trouble in that vw 1.6 engine

Chances are I have this arseways? but driving an old yoke, my impression with friend's new(er) cars and their fuel consumption is that the differences in fuel consumption between "spirited" driving and normal everyday driving is much narrower than in the past. So if they average say 35 mpg, hammering it they'll return 30 and driving easy they'll return 40 mpg kinda thing and diesel seems to have that narrower range more than petrol? Whereas with my 90's engine I can easily see high 30's on long runs on a light foot, but if my foot goes to the floor it turns into a well engineered leak(well under 20 mpg, more like 15).

I have completely opposite experience. Turbo-charged petrol engines are much more sensitive to driving style than naturally aspirated.

Short journeys.
38 or so mpg so far.

About what I expected when buying.

Update.
Looking at 42 or 43mpg average on longer (over 20km) trips

33mpg average on the last tank of very, very short trips. Took a month to use a tank!!!
