umm.. no... where have you been hiding?
eaton has had superchargers on so many OEM brands
Aston Martin
Ford
Jaguar
Mercedes
.. etc..
But yes, that 'Twincharged' VW is a nice little car... I would love to have one.. the power is seemless.. especially for a little 1.4L

As far as I know this is a european only car... technology like that is too expensive to bring over here to the USA right now... we'd rather have a bigger engine.
Give it 5 years or so and we might see it.

Yeah, that's it. It's much more efficient to twincharge this way rather than how we have to do it. You're not limited with airflow by the blower like we are. In this setup, the supercharger pretty much just spools the turbo up quickly while providing instant boost and then the turbo takes over as well as the bypass opens so that the turbo gets fresh air rather than hot supercharged air at high rpms.

Ah VW. just when something seems simple enough to get the job done, they make it more complex (,expensive, and less reliable)
does the SC pulley have a clutch to disengage it? it would be a waste at high rpm if it didn't.
and why not use 2 different size turbos?

You know... you are probably right... a sequential turbo setup would have probably done the job just as well... and had a lot less parts.

Umm... it does have a clutch
and sequential turbos cant touch it for boost response
Oh, and it has won International Engine of the Year award 2 years in a row!

I'm not questioning it working well, i'm sure it does. but replace the blower with a small turbo, keep the bypass valve and it would probably work as well, but be a lot less complicated. but thats how VW likes to do things.
my favorite little gadget they have is the locking motor mounts on the v6. they are normal soft motor mounts most of the time, but above a set throttle level a pin engages and locks the motor mounts, making them solid. in theory its a cool design. in reality its a nightmare of poor reliability and a full days project just to get to the darn things when they break.

how would it be less/more reliable?? Superchargers are used on many OEM cars already.. so are turbos... so are electromagnetic clutches.. i guess i dont see the complexity difference over adding a second turbo..
By adding another turbo you still dont get the response benefit.. yeah it will be less lag but still, nothing close to positive displacement SC..
