Very very clever.

Compound charged engines arn't new the last "mass produced" unit I can think of was in the K10 Micra Super Turbo. VW have also been making nutty engines for some time I've one of there 1278cc 35mpg 113bhp units that's 15 years old and now putting out 136bhp in a car lighter than a Mk1 golf.

The engine in that Golf is not compound charged. It is twin charged which is different

[davidstone28]

I think the 'newness' is in relation to how successfully it's implemented in term of a flat torque curve, linearity of the power delivery from the twin chargers, all balanced with fuel economy. If this engine anywhere as good as the review concludes, I'd suggest its the first genuinely successful implementation of its type in a mainstream car.

Great!

All we need now is for VW (and other manufacturers) to put their engineering masterminds towards making cars lighter and therefore inherrantly more faster and fuel efficient - instead of making them fatter and slower but with bloody big crazily complicated engines.

That would be a real engineering breakthrough IMHO.

mazda mx5 ftw then

What I mean is. We should be using advanced technology such as carbon composites, to create cars that will still get 5 star in euro NCAP, but weigh only 1000kg, yet with a crazy dual turbo supercharger 1.4 deisil hydro electric mean machine engine.

Stuff just aint going no where. Cars are getting so heavy. Engine technology improve's to counter the weight - but ultimatly, it's just fire fighting. If cars were made ultra light yet ultra strong we would be in heaven. Its the way forward

what i meant was - the new mx5 weighs something like 10kg more than the mk1 (thats 17 years old) but has all these things with them as well. weigh over a tonne, granted, but the engineering is impressive nontheless. just need their rotary engine to save that little extra. or please. pretty please. put the damn 1.8 v6 in there

[Howard]

170bhp & 7.7secs from a 1.4 is somewhat impressive though in a car that weight!

Err, a combination of turbo and supercharger as far as I'm aware is known as compound charging. I've never heard of twincharging until VW penned it as a name for the new Golf engine.

Are you perhaps mistaking it for compound turbo charging? That's something totally different where the output from a smaller turbo is sent to a bigger turbo?

[XA04]

Wow, VW have been very clever recently!

[GoNz0]

doubt it will be all that reliable in the long term...

[BenW]

All very good but its not really any better than something like a saab HOT aero 2.3 which is 250hp turbo, 0-60 in 6.5, 155mph and 31mpg.

OK so the mpg is lower but its much faster and no doubt more reliable

I'm not making any mistakes.
Compound charging is where the turbo outlet feeds the supercharger so there are 2 stages of boost - the boost coming from the turbo is boosted to X PSI, then the supercharger further compresses it - in effect compounding the charge.

The Golf's system uses a supercharger for low revs, then disengages it at higher revs when the turbo takes over. No compounding of the charge occurs here.
Compound turbocharging is the other form of compound charging.

In theory, you could compound supercharge aswell with a bigger supercharger feeding into a smaller one but that would probably be a pointless waste of energy.

Then we also need a new way of buying cars. At the moment a lot of manufacturers don't make much money on the sale itself, they rely on finance and maintanence costs for profit. A side effect of these complex parts is the bills are that much higher when it comes to fixing them.

I'd like to see cars use simpler, more modular systems that make repairs and maintenance cheaper (remember that concept plastic panel based fiat? Panels were solid colour through out, no need to paint over scratches etc ), but that doesn't do the industry many favours.

Ah right - good post.
