It took me a couple of weeks of ownership to understand what B mode was doing and now it's my default mode for driving as it gives one pedal driving, even in hybrid mode with the petrol engine running. My understanding is that there aren't that many hybrid cars on the market that allow one pedal driving when the petrol engine is providing the drive. Whether you like that or not is down to personal preference I guess, but as I'm sort of used to it when I drive my wife's car (a full EV), it's not that strange for me and I find I much prefer it.
For the first couple of weeks, on my daily commute (13 miles each way, mostly A roads plus 8 miles on a dual carriageway), I'd run out of electric range even though the car would say that it had around 38-39 mile range at the start, I'd struggle to get home after 26 miles driven without using any petrol. That was using D mode.
Then I discovered B mode and I can now drive the 26 miles of commuting plus a little more driving around where I work during the day and still get home with around 5-8 miles of electric range left. Today I managed 41.6 miles before the petrol engine kicked in as I'd run out of electric range. I was only a couple of miles from home, so the car told me I'd achieved over 700mpg for that journey.
Clearly not a realistic economy, but now I'm on Octopus Intelligent Go with an Ohme Home Pro charger (supplied and fitted by Volvo for free as part of the deal), I'm loving just how cheap my commute is. Octopus just reduced the overnight charging rate to just 3.49p/kWh, which is crazy cheap! Last week I used £2.04 in electricity to commute to/from work for 5 days and used no petrol at all. My previous Kodiaq 2.0 diesel averaged 16.5p/mile over the 4 years I had it (accurately measured using an app on my phone to record every tank of fuel I put in it), so that was around £5/day to commute plus a few extra miles. Unbelievable just how cheap my XC60 is to run at the moment.
