Having purchased a p460e, I was curious as to what the difference was in the powertrain / engine compared to the p550e. I was uncertain whether the power difference was due to a reduced engine output, or a reduced electric output. I couldn't find the information anywhere online. However, after purchasing the p460e and receiving a confirmation certificate for the vehicle, I can confirm that the p460e has the 394hp rated 3.0 Engine and the 215hp Electric Motor. (Exactly the same as the p550e)

Therefore in conclusion: The only difference is the amount of electric assistance the motor is allowed to add when in hybrid mode. My guess is that in hybrid mode in the p460e, the electric motor adds 60hp, and in the p550e, it adds 150 hp. In all other modes: electric only, and engine only, both vehicles have identical power figures.

This explains why there are companies out there online offering a 'power upgrade kit' (not a remap) for the p460e to convert it to a p550e, as I'm guessing it's just telling the software to add more electric assistance.

I hope this information is helpful to anyone who is looking to purchase either of these vehicles.

That's interesting. I also have a p460e and have looked at these companies offering the upgrade, wondering what it is they actually tinker with.

How did you get a confirmation certificate? Not heard of that. Also, would it be right to assume that the p550e eats through the battery charge more quickly then? 2024 RRS L461 P460e AB

I got the certificate because I leased the vehicle through my limited company - hence the Ltd company got sent the confirmation certificate! 2024 3.0 P460e

Yes theres a simple software update (not remap!!) that converts a P460 in to a P550e with ease and its undecectable at all.

Thanks for the detailed write-up — really useful info! Just wanted to clarify one point, as I think there might be a misunderstanding about where the extra power comes from in the P550e.

The difference between the P460e and P550e isn’t in the electric motor — that stays the same in both models (around 142PS). What actually changes is the petrol engine output, which is software-limited in the P460e to 300PS, whereas the P550e allows the engine to deliver 360PS. That’s where the extra power comes from.

So when people talk about upgrading a P460e to a P550e via a software update, it’s not about adding more electric assistance — it’s unlocking the full petrol engine output. Once that’s done, the hybrid system is allowed to reach the full 550PS combined power, just like the P550e.

Interesting

Do you have the same information with regard the P440e vs 510e ?

What is the difference between the P440e and P460e ? I think I read that the electric motor has more power.
