Additional horse power through super charging and twin turbocharging

978 Views 10 Replies 6 Participants Last post by  Wayne T5
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?
