Hybrid versus petrol and diesel: a comparison of real-life fuel consumption
Thanks Gerrycan. As an interim mpg figure, over 5747 miles the Octy has averaged 85.2 mpg in real-world numbers. It's likely to be much higher since the last refill as I've used mainly e-power for the last two months. I read today that your former pm was nicknamed Side Hustle Scotty as he appointed himself to five ministerial roles in addition to being pm. One writer was quoted as saying that we all know people who can't do their own job but reckon they can do everyone else's better. At least Australia in not rudderless now, unlike the UK where little seems to be under control and not likely to be until the new pm is in place in September. I just hope that a plague of locusts will not be the final crisis to challenge us poor beleagured Brits!

Hybrid versus petrol and diesel: a comparison of real-life fuel consumption
I'll be able to check real world mpg when I next refuel as I keep a spreadsheet of fuel details - cost, volume, etc. However it could be a while before I report - I last refuelled 9 weeks ago and the tank is still 3/4 full. Yesterday I did a 26 mile drive on e-power. I drove fairly slowly on narrow country roads and after 26 miles, there was still another 10 miles range indicated. The aircon was on, so I'm very impressed.

Hybrid versus petrol and diesel: a comparison of real-life fuel consumption
For the first time I drove on e-power unil the engine started. The journey was 38 miles, 27 were on e-power and the overall mpg was 241. It was 29 degrees outside, so the aircon was set to 17 degrees. Because of regen the battery still had 5% at the end of the trip. I'm very impressed!

Please replace key battery...
I received the 'replace battery' message recently, fitted a new Panasonic one and the message went. However, it's only about six months since the last replacement so possibly the red flashing light on the fob indicating it's in contact with the car, including the asssociated circuitry, may be using up more power than my previous Karoq's Kessy, which didn't need replacing for the two years we owned the car. The light flashes on the fob inside the house until I move another room away.

Hybrid versus petrol and diesel: a comparison of real-life fuel consumption
Hi Gerrycan. I last filled the car on 15th June and it cost £1.83 per litre. In the UK Octopus Energy provides four hours of off-peak charging for 7.5p/kWh, which is why our iV is so frugal on fuel costs since we rarely drive long distances. I would not recommend an EV for the UK as the charge points are very expensive. On June 4th the average was 44.55p/kWh. Cheaper than petrol but it takes time to recharge and there is the anxiety of finding a charge point in more remote areas. My recommendation would either be a diesel engined hire car or the Honda HR-V or Jazz self-charging mild hybrid. Both of the latter are extremely economical and my sister-in-law's Jazz is more economical on a slow commute than on a long fast drive. Enjoy your visit to the UK and don't forget to visit Yorkshire, God's Own County!

Hybrid versus petrol and diesel: a comparison of real-life fuel consumption
My understsanding is that 102 mpg refers to the amount of petrol used so it cost about £5.50 for petrol and 78p for electricity ie 9p/mile. Half our motoring is on e-power so the calculation in the first post of this section indicates that the annual cost will be 7.6p/mile. I think the 73% emissions free figure is optimistic. Next time I'll note both the petrol and e-power range before a journey as well as after.

Hybrid versus petrol and diesel: a comparison of real-life fuel consumption
When I speak to friends about 'emission-free' motoring, I usually add 'at the point of use'. According to Octopus Energy, so far this month our 100% green electricity has meant 64kg less CO2 emissions, equivalent to the amount 32 trees absorb in a year. Isn't it clever that they can supply green energy on the same cables as all my neighbours using other suppliers.

Hybrid versus petrol and diesel: a comparison of real-life fuel consumption
I had a drive yesterday in N Yorkshire. The roads were 'undulating', so there was quite a lot of regen going on. I don't often check the onboard data, but when I reviewed it, I'd covered 58 miles, 42 miles (73%) were emission free and the overall mpg was 102. This reinforces my opinion that the Octavia iV is the best car Skoda has ever produced, if only the early software issues had been sorted before release.

IV Regenerative Braking Setting
I set the regen to maximum when we first bought the car. I rarely need to use the brakes as the regen is so effective: around 700Wh added to the battery on a long 3-mile hill near here. I sometimes use the cruise control as a brake controller. For example if set to fifty and I approach a speed limit, I adjust the setting as appropriate and the car drops speed quickly. This may explain why the Enyaq has rear drum brakes: the front disks do most of the braking anyway and with a more powerful e-motor than our iV, presumably the regen braking is also more effective. I didn't know about using manual mode to adjust the regen, so I'll try it out later.

No dedicated HVAC controls
Our aircon is always on. If it is turned off for a while, the seal can deteriorate, refrigerant will leak and the aircon will fail. Our 02 reg Octavia was 9 years old when we sold it, the aircon had been on all that time and never failed or needed regassing. Modern aircon units are very efficient and don't affect mpg significantly. Our voice control works perfectly for navigation, setting aircon and radio.

Use the voice control to adjust the heater settings.

Hybrid versus petrol and diesel: a comparison of real-life fuel consumption
Re DavidY 'I imagine the official range figure for an EV is the other way around to an ICE; made up of good figures in urban areas, but poor economy at constant speeds on fast roads.' My sister in law has a Honda Jazz hybrid and gets better mpg on her commute into Manchester than on a long drive.

Hybrid versus petrol and diesel: a comparison of real-life fuel consumption
I'm charging the car regularly using off-peak electricity as I'm now maximising the use of e-power. The latest bill shows that the car cost £6 for 240 miles of motoring, with minimal use of the IC engine. After filling the car one month ago, the fuel gauge still registers full, but I estimate that I've used 1 1/2 gallons of petrol which equates to a total cost of 8p/mile, quite close to the figure I gave in the first post on this topic..

Drive Modes
I checked out iV last week and in sport mode and manual it stays there until it's deselected. I was in e-mode and it immediately went in to hybrid when I switched to manual. There is also an indication of the preferred gear when in manual too. Our Karoq had an override so that if the manual gear was too high or low it changed for you. I usually leave it in auto, but manual is great fun for a short while of fast motoring.

Octavia iv. Is it a 13kw hr battery or a 10kw battery?
The iV has a 13kWh battery and we get about 30 miles on e-power in summer with the aircon on. I might test it with the aircon off to see whether there is a significant difference. We live in a hilly part of the country, which will affect energy consumption. It drops to around 20 miles in winter owing to a less efficient battery and the heater being on. In wet weather the headlights come on too.

Ours was delvered in May 2021 and it reverts to auto after a short time in normal. I haven't checked this in sport mode.

Hybrid versus petrol and diesel: a comparison of real-life fuel consumption
The Octy was within our budget and suits out needs for comfort, handling, acceleration, with plenty of room for our greyhound. All our journeys since we bought the car have been within the range of the battery on hybrid power, except for two of 120 miles each way to visit my brother. He has a charge point, so I plugged in to recharge for the return journey. A diesel engine would be unsuitable for our style of motoring, as would be petrol alone. Our Yeti diesel and Karoq petrol returned 36 mpg and 31 mpg respectively, the latter being skewed by much of the driving during lockdown being 8 miles a week going shopping. The Octy iV is obviously not suitable for business use where long distances are involved, but for us it's perfect.

Hybrid versus petrol and diesel: a comparison of real-life fuel consumption
It was calculated using the last refuel at £1.83/l and electricity at 7.5p/kWh. There was no need to recharge for the return journey - after 61 miles the battery was at 10%
-
Hybrid versus petrol and diesel: a comparison of real-life fuel consumption
Today we did 61 miles in hybrid mode. Using the car's computed data we used £5 of petrol and 90p of electricity, ie just under 10p/mile. Our Karoq cost nearly 18p/mile, when petrol was 'cheap'.

Drive Modes
One of the benefits of the hybrid is the braking effect produced by the regen system. I hardly use the brakes going downhill, particularly when I set cruise control. When approaching a junction, I only use the brakes to provide a complete stop. Also, the regen charges the battery: going down a steep approx 3-mile hill near home it adds about 700 watts.

A gearbox problem solved by a reboot of the infotainment unit - does this reset the MIB unit?
This morning I was about to back the car out of the garage, but when I pressed the start button, an error message came up. I can't remember the exact wording, but it related to a gearbox fault and failure of the parking brake. When I tried to engage reverse, it went back to neutral. So as with other faults, I rebooted the head unit, then it all worked. Later, when I went for a drive, the image indicating 'emission control system fault' was on. Another reboot cleared it. So my question is this: when the head unit (infotainment centre is rebooted, does this reset the control unit (MIB)?

If you look at vehicle > data on the infotainment screen, it will show the range for the petrol and battery, so note the figures before and after a journey to check the consumption figures.

Hybrid versus petrol and diesel: a comparison of real-life fuel consumption
A good point. We had a budget for the Karoq replacement and the Octavia iV suited us perfectly for reasons stated elsewhere. When we bought it, the massive increase in energy costs were not apparent. So with our gas and electricity costs quadrupling and doubling respectively, the savings in vehicle fuel costs are welcome. I am amazed at the mpg figures for the petrol and diesel Octavias. However, these are for long distance journeys which are not our pattern nowadays. Our 02 reg diesel Octavia once returned 70mpg on a motorway journey averaging 55mph, when I was working and regularly drove long distances. I like matrix2002's comment about a friend not filling up for nine months! Incidentally, our latest electricity bill indicates that we saved £19 by charging the Octy overnight.

Hybrid versus petrol and diesel: a comparison of real-life fuel consumption
Another advantage of the hybrid Octavia is the bik of 7% compared with 28% plus for an IC vehicle. As long as the company pays for business use fuel, then for private motoring with the significant tax benefit and e-power for short-ish journeys, it's a big bonus.
