B4 fuel consumption

Only done sub 7k in the car, mainly local knocking around.

Just back from Centre Val de Loire where it did 1500 fully loaded, with some nice steady runs for a change.

Overall ave now 36.7mpg, with the journal showing 46.8 on one stretch.

Colour me easily pleased. But happy with that. Is it typical for a still new (ish) 2 Lt petrol?

I'm getting 37.53mpg averaged over 7,800 miles so that's about right I would say.

Just got back home (Czech Republic) from a road trip to Istria, Slovenia, Trieste and the Italian and Austrian Alps, about 2000 km in total, with a lot of pleasurable mountain and coastal meandering as well as long 120-130 km/h motorway stretches. The car (B4, took delivery early July) behaved impeccably throughout, and I got 6.1 l/100 km for the whole trip, which translates to 46 UK mpg. The trip computer reading tallies with my own calculations based on how much petrol I put in. I was just driving normally, which for me means calmly, with a light foot and without any stress, but still getting a healthy move on and not obsessing too much about fuel economy. I'm mighty pleased with that, seems like the mild hybrid is doing its job very capably 🙂 I noticed that longish and frequent periods of motorway coasting (when the engine switches itself off) seem to make quite a difference.

I have T4 FWD and my fuel consumption on the same type of journey and driving style is 1.5 L / 100km higher. The newer mild-hybrid engines are indeed less frugal than the classical turbo ones.

So you're getting 7.6 l/100 km with the T4 compared to my 6.1 with the B4? That's quite a difference if we're comparing similar journey types and driving styles, though even 7.6 isn't terrible for a 2-litre engine pulling not the lightest car. With classical turbos, fuel economy tends to be ultra sensitive to driving style.

MY2020 T4 FWD official WLTP figures are very close to my real world consumption: high speed driving at max 130 km/h is listed with 7.4 vs my actual 7.6 l / 100km.

Looks like we're there or thereabouts then 👍🏻

Have had up to 48.6 on a long run. My app says 39.7 0ver 4437 miles. B4AWD 22 model, just over a year old. Delighted with these figures but I drive with a very light foot.

39.7 overall is excellent 👍🏻

Regular get mid-50's on a run from a B4 FWD - needs a light foot to get the best out of them though ;)
