4 pots + 2 turbos = BMW straight 6

[Sankekur]

Opel renault mazda all have 2l engines with power in the 190kW (opel has had that for a long time now) so I would think that BMW should also be able to do that.
Also compare the BMW and Merc twin turbo V12's I mean the merc has been using the same one for years now (the 65 engine) yet the one BMW made is still a good 50HP and 300N.m (somewhere in that region) less than that engine.

i think all cars should be boosted i just wish they would rather go the less efficient but lag free supercharger route...

In theory the supercharger car is lag free but when you take into concideration the power loss to get it to start driving the charger it is making less power initially than the engine could have made. Today there is no BMW turbo that has lag. It feels like lag though because the torque climbs so rapidly that it gives a lag perception.

But what's the torque like on that motor?

focus st. 2.5 turbo, 166kw and 320Nm
golf 6 gti 2l, 155kw

You cannot compare those engines to the BMW, seriously, mazda, opel and renault? The Mazda gets eaten by 147kw audi's and golfs, so I don't believe that engine makes 190kW (dyno sheets also shows this). Remember, kW is not everything, the integral of the kw/rpm graph is more important, as this will indicate acceleration. This is also why the BMW engine has better 0-100 times than all those you mention, even though it is likely heavier, being an X1...

+1. I have driven NA cars with more laggy feel than modern BMW turbos.

No disrespect Sankekur, but have you ever tried to drive the S65 quickly through a corner? You WILL lose the tail, and you WILL damage your pride, if not your your vehicle... It is EXACTLY for this reason that the BMW 760iL has less torque, i.e. to maintain drivability. If you have seen the topgear special, you will also see that the 760iL makes mincemeat of the S65, in BOTH the corners, AND in a straight line... Power is nothing without control...

PS. The Mazda MPS has a 2.3l turbo making 190KW, and the Opel Astra OPC makes 177Kw, NOT 190Kw.

The Renault 250Cup has 184Kw, and 340Nm Torque, but at 3800Rpm, which means less tractability at low revs, that's why the quoted 0 to 100 time matches the X1's 6.1seconds... it SHOULD be way faster, don't you think?

None taken, I always assumed that it was just bad suspension and chassis setup seeing as AMG's are basically the same as the normal models just with big engine, and the fact that not all the torque the motor is producing is actually delivered to the wheel, but I like the fact the the engine can do it even if the chassis can't handle it.

Another thing to consider is that BMW could have down tuned this engine to fit in with the range (and meet correct emission standards).

Once it hit's the "tuners and chippers", we'll start getting a better feel for this engines true potential.

First off don't compare a 760i to a an S65, compare it to an S600.

Secondly, 180kw is a LOT from a 2.0t in a 'normal' car. It's not a GTI, RS, Audi S car etc, it's a frigging repmobile peaking at 5000rpm so it's a small turbo. Wait until the higher performance models come.
