Hi, proud owner of the civic e:hev advance.
Drives better than any car ever owned, but struggling to achieve the 4.2l/100km it convinced me into buying it.
More on the 5.8l, driven around 20% urban and 80% motorway, hitting 130km/h max.
Anyone can confirm these number?
Thank u all

I don't know anything about the hybrid civic but I assume it works just like crv hybrid. The hybrid gets it's great fuel economy through regenerative braking. So if your doing 80% of your driving at faster speeds with little breaking it will be closer to a non hybrid vehicle. There is a lot of other factors that play into your overall fuel economy. If the advertised fuel economy is 4.2L/100 and your only getting 5.8 that is a pretty big gap. I'd just assume it is more your driving habits.

What type of fuel are you using? I don't know too much about the hybrid or what it can use. What I'm getting at is ethanol content in the fuel? I'm guessing it can use up to 15%. The higher that percentage the worst the fuel economy. You can Google that and the government will tell you all about it. Just use the keywords does fuel with ethanol in it get worse MPG? E85 for example 50ish to 85% ethanol. Ran in a flex fuel vehicle designed for it gets about a whopping 27% less MPG. You'd have to calculate a 27% drop and the price difference between it and pure gas to see what would be the better route to take.

I get 32 all around. If I go exactly the speed limit on the highway I climb to 40 quickly. I do 85%~90% city driving so that means any average I watch through the computer is skewed heavily to city driving, and I get right on the money and drive fast.

That being said my trim is advertised as 32/42 or something.

Advertised 4.2l/100km consumption that you mention comes from a NEDC test which is an old standardised way of measuring consumption. Newer standard is WLTP for which Honda advertises 5.0l/100km combined or 4.5/4.2/4.5/6.2 for low/medium/high/extra high speed ranges (see speed graph below) for Civic e:hev Advance.

WLTP is replacing NEDC which is somewhat obsolete these days as its results are not realistic.

Tests are executed on a dyno inside a thermally regulated garage (~23°C) following a strict speed profile (see graph below). Drag is simulated. Due to regulated environment temperature heater or AC is not running, etc. Google "WLTP test" for more information.

I've had my Civic e:hev Advance since mid november and with a mix of relaxed and spirited driving achieved overall fuel consumption of 6.1l/100km in these 4500km. On longer relaxed motorway cruises with cruise control set to ~110km/h my consumption was 4.8l/100km and on longer relaxed intercity cruises (speeds between 50 and 90km/h) my consumption was 4.2l/100km.

I don't see these figures beeing too far from advertised, especially when accounting for winter season. My total average of 6.1l/100km apart from spirited driving also includes a good portion of 160km/h highway cruising which by itself averages at around 7.5l/100km.

A more realistic fuel consumption for the Civic EHev is 5.5 lt/100 km (45 miles/US gallon, 55 miles/UK gallon). This would be for 50% city and 50% highway.

To get the best fuel economy go easy on the accelerator and keep speeds on the highway at 110 km/hr (70 miles/hr) or less. Fuel economy drops like a rock over 120 km/hr (75 mph),

Non-hybrids do almost the same fuel economy on the highway as hybrids do. Hybrids get MUCH better fuel economy in urban driving than non-hybrids do because they just use battery power at lower speeds. The ideal customer for a hybrid is someone who spends more than 50% of their driving in urban environments.

Judging by your stated use, you are far from the ideal customer for a hybrid. If I was doing 80% highway driving I would have bought a non-hybrid car.

If you drive on motorway, the fuel consumption is higher and similar to a non hybrid car. I got similar consumptions with my old HR-V non hybrid (but with 1.5L instead of 2.0L we have on the Civic).

The consumption is higher in cold season; now with the summer you can easily obtain 4.2 or less l/100 km.

My consumption on over 24.000 kms is about 4,5 l/100 km.
P.D.: I try to add the link to my car consumption registered on spritmonitor.de, but I am not able to insert links.

Im at an avg of 5.3 over 32k km ( 80% outside and 20% in the city ). Everything people here said is true ... Once you go over 120 on the highway, the fuel consumption starts to sky rocket for every 10kph over. My biggest gripe is the fuel tank. I have never been eble to put more than 32L of fuel in it (this was with 0 km on the dash for about 20km):p:p

It's a shame Honda restricts their top trim to hybrids now. I'm definitely in the "more highway than city" driving group, but I like the touring trim due to the creature comforts. At least there's still some improvement in MPG when driving on the highway vs non-hybrid trims.

Just completed another long road trip to Las Vegas and back, over the mountains and across the desert. Car now has 4,275 miles on the odometer and the Trip B computer, which has never been reset, reads 48.9 mpg. The Trip A computer auto resets at each fill-up and I'm normally getting right around 50 mpg give or take. I drive completely normal, just like all the other cars on the road. I have not used ECON mode due to it's affect on the A/C which has always been on.

This is my first hybrid and considering all the situations I have experienced with it from high mountain passes to massive inner city traffic jams I cannot imagine having bought a non-hybrid vehicle rather than this one. I'm completely sold on the tech. It does so many things, so well, it's a complete no-brainer.

Caveat on this, as I discovered with a 2020 CR-V Hybrid: the first 10 minutes or so of driving, even in "urban environments", is typically going to be using the ICE engine as the battery warms up. So you need to be doing urban driving that is longer than 10 minutes from a cold start.

A 30 minute trip in the city got terrific fuel economy, but in general daily use over the course of a year (across four seasons) I got about 34 MPG (US), which wasn't enough to offset the lack of oomph over 60 MPH in that car.

I'll take the 30-ish MPG that I get with my 2022 Civic ST with the 1.5T engine. Given that I drive about 7500 miles per year in my car, the difference would amount to 30 gallons a year, which is not a big deal. And having a 6MT is more fun for me, too (usually).

On the other hand, I'm very curious about the new 2025 Civic ST Hatchback Hybrid, as it seems to be much better performing than that 2020 CR-V Hybrid on the top end (I've passed it on to my daughter).

But if the hybrid benefit in fuel economy is still like the CR-V Hybrid was (that I would need to drive for 10 minutes before I start to see real benefit from the battery), I would be more inclined to just stay with the car I've already got, until I have a better reason to move to another car. Most of my local driving is in the 15-20 minute trip range.

How is that possible ??? i just bought few weeks ago brand new eHEV 2024 (advanced) Europe version. my air temp was 1 degrees celcius and i got short trip 90km/h climate control off 5.2l/100km ( short 20 km trip). Than turned climate control on and got 5.8l same trip. And than i done city drive like 20 km climate control off and i got 3.8l. Is something wrong with my car? its brand new. why it takes so much fuel! i mean specially on 90 km/h its way way too much people getting under 5 liters in main road aswell.
