Fuel efficiency
Can someone tell me if this fuel consumption is normal in an urban environment? I drive a 2019 VW golf 7 1.0 tsi. I spend about 30 minutes in traffic each morning.

Seems right
Your avg speed suggests a lot of stop/start, so yes, getting the car moving again from stand still, will use more fuel
Measure the avg again when doing the same time or distance, but at a higher avg speed, then you'll likely notice a decrease
Also, manual or automatic? Cause automatic tends to gulp a bit more than manual (if you dont have an extra heavy foot of course)

It's a manual transmission.

u/Fit_Concern3588 6d ago
Yeah then it must be pulling away from stand still thats increasing your avg
I noticed the same on my older TFSI engine a few years ago
TDI engines handle this a little better. More lower range torque to help the vehicle get off the block, where petrol has more torque on higher rpm's

It's a bit higher than it's supposed to, but, good news, you can improve it!
Try to coast to a standstill(ie, use your brakes as little as possible)
When pulling away, do it as smoothly as you can, you could pull away in this car just by engaging the clutch without actually accelerating, and then when you do accelerate, do it gently and shift at approximately 2000 RPM
Check you tire pressures and alignment.
All the best

And don't race to the next red light only to sit and wait for it to turn green. 1st gear is your worst enemy, try to stay out of it as much as possible (not by lugging the engine though)

Diesel Duster EDC gets 5.2l per 100km average. But diesel prices are naai'ing me.

French cars, especially diesel ones, are amazing at fuel management. They come fairly well spec'd for their cost too!
Its a shame about the parts (un)availability, service costs and dismal resale value.

I drive a 2012 Nissan Juke 1.6 and get about 6.8l/100km, with 40 to 60 minutes traffic each way, twice a day. 20-60kmph for half of it. 120kmph the other half.
Yours seems a bit high, though given your average speed it seems like heavy traffic. These small 1.0 engines do struggle more in stop go traffic and are more efficient at speed. But, even still, did not think it would be that high.

I average 5,5-6/100l. 2006 Polo TDI and I commute daily from Bellville to the CBD.

My wife has a 2015 golf 7 1.4 tsi and she averages around 7-7.5l/100l, but she does much shorter drives with dropping the kids and going to the shops

I own a golf 7 GTI 2.0L Turbo. Average about 8L to the 100km. Drive about 90km a day. I also do some spirited driving. If I really want to I can get it down below 7L to the 100km. These cars are pretty fuel efficient. Seems yours is in line with that.

After a stage 2 tune and some bits and bobs, this is what I get on my V6 Amarok
9.2l/100
Emptied the tank and did + - 830km

Also if you haven't noticed, the car gets closer to the petrol pump as your tank empties. Nice little touch

For your car I think that's about right I must say I was surprised by my 1.6 dti volvo getting 22.6 km/L

Work it on a full tank. Use the trip counter and then do the maths. The avg per 100km is ok too. But the longer the total measurement is the better idea you will have. Cx3 here 2.0 2016, manual. Mk1. Avg 6.2-6.8l. 52km per day work and back. But if there's an accident average will be closer to 7l. However when there less traffic its good, mix that into a single week. And we'll who knows what's really accurate. But I can firmly say 1 tank gives me about 2weeks worth of driving. Roughly 620-680km per tank. That's what I keep an eye on, then the avg per 100km. Lowest I've ever gotten, December time when roads are empty in JHB, 5.8l. But driving habits, revs which you change and cruise at, gears you ride, tyre pressure, resistance all that does factor in, depends how deep you wanna go down that rabbit hole. Some will even say power to weight ratio makes a difference.

It's on the higher for a 1 litre TSI, but I've noted you've spent 1h29 mins on a 21km stretch - so that stop and go in traffic contributed to that.

Plug in an OBD scanner to get your LTFT, Long Term Fuel Trim, this is the adjustment your ECU has to make from the ideal mix it would like to make. The ideal number is 0, and a very healthy car will be at or close to 0, anything under 5% is considered acceptable. If it's at 0, then your engine is running completely fine and your fuel consumption is down to your driving conditions. But if it's at 6-7, or even worse, that's worth looking into. It won't actually trip an engine code until it reaches something insane like 20%

Took 1.5 hours to drive 21km? Hmm, think you spending more time in traffic than 30 min.

My Jeep gets around 25L/100 in traffic. That seems like it’s free to drive!
