Additional horse power through super charging and twin turbocharging

Hi there,

I recently acquired a 2018 Volvo S90 T4 Inscription (essentially full option), which has 190 BHP. Since it also
has twin (?) turbochargers and super charging, I was wondering how much additional horse power
and torque (if any) is added through these extras ?

Thanks !

The supercharged and turbocharged US version is called T6 and has 316hp
The turbo only version is called T5 and has 250hp
In the US we don't have T4.

Both T5 and T6 can be boosted a little more with polestar upgrade.

Not sure of your question?

Perhaps it's a D4?

The T4 only has a turbo. It's a detuned T5.

Ah yeah, I wasn't sure about the supercharged indeed.

Well, same question then with "super charging" deleted ?

I would be guessing, but around 30-40 hp contributed by a turbo.

So as an extra, above the 190 BHP, or as part of the 190 BHP ?

Do you also knows what happens with the torque ?

No, it's part of the 190 bhp your engine is generating. If your car did not have a turbo it would be generating less bhp. Torque is around the same.

T4s have about 30 less lb/ft of tq and about 60 less HP than a T5. And apparently only FWD? And noticeably better MPG ratings.

It just feels so much more swiftly, reactive and powerful than my Volvo S80 D5 (previous car), which had about the same BHP, that I started thinking that the engine of the S90 T4 was stronger nevertheless ...

I think you're feeling shorter gearing from a different transmission - that plays a large role.
