Ordered a B4P Inscription mid June, have been told by dealer to expect late September for delivery (UK), it appears most other people have been advised early September for those that ordered mid June , maybe the dealer is going to exceed my expectations and deliver earlier than advised.
Can anyone help tell me the difference between the T4 petrol engine which is now badged at B4P ?
Can't wait to take delivery of this car, my first premium car experience.
Enjoyed reading the forums, and learning about my new to be car.

I believe the difference is so small, you'll barely notice the difference.
I'm moving from T4 in my XC40 to B5(P) in a V60CC.
As far as I can tell, it's just a beefed-up starter motor that can work in reverse for recuperation + extra battery capacity.
Benefits for all: Smooths out stop/start (most of the time - there are reports that it can get confused & be quite jerky, which would be a major fail).
Benefits for town drivers: Slight improvement in economy due to recuperation, initial acceleration, & more use of recuperated battery power for climate, audio, etc.
Disadvantage for motorway drivers: Unnecessary extra weight to lug around.

Just an update on my delivery dates, was originally given late September, then the 06th October, but now had a call from dealer and should be picking it up on the 18th September.
Read the manual, got the screen protector, good to go.

There are initial reports on the mild hybrid engines (B4) returning better mileage than the previous generation (T4). I haven’t seen a specific comparative test made on XC40, but the conclusion in this video could mean that you should expect lower fuel consumption (go to min 14) https://youtu.be/c7I8vMjq4Ow
The B4 is a 'mild hybrid'. In mild hybrids there generally is a device which replaces the starter and alternator with a single device which assists the powertrain. I presume that is how it works in Volvo as well. Having driven B4 models the biggest change is that the Stop-Start works really seamlessly unlike the rubbish implementation in the older XC40 models!

I have the T4. The B4 is what's known as a Mild Hybrid.
The stop/start system on my T4 works flawlessly and causes me no concerns.

Agreed - I also have T4 & no problems (B5 on order).Joe Bloggs wrote: ↑Fri Sep 11, 2020 7:09 pm I have the T4. The B4 is what's known as a Mild Hybrid.

T4 is flawless for many drivers. Those that complain about T4 will, sure as eggs are eggs, complain about the B4.
If you're a gentle driver, B4 will be ever so slightly better as there are milliseconds improvement at getting going again. However, in order to improve economy, B4 will cut out BEFORE you come to a stop. This may cause you issues if you suddenly decide to hoof it again.
To summarise, aggressive drivers should switch to dynamic for enthusiastic city driving, as a pragmatic solution to bypass stop/start & improve take-up.

Having driven both I have to disagree and I am not an aggressive driver. In my T5 the Stop-Start is too eager to Stop and lazy to re Start. In the B4/5 it doesn't make use of the starter motor and as a result the whole process is far smoother to the point of being almost unnoticeable. Using dynamic mode is a red herring.Silver Moose wrote: ↑Fri Sep 11, 2020 9:39 pmAgreed - I also have T4 & no problems (B5 on order).Joe Bloggs wrote: ↑Fri Sep 11, 2020 7:09 pm I have the T4.
