    Some highlights of the new engine generation, not 100% sure if all are on the TDI:

    exhaust manifold integrated into cylinder head, this makes the whole package smaller and cools the exhaust. This lets the engine run higher combustion temperatures, which increases efficiency on gas engines. I don't know if that's good since higher temps = more NOx, the problem w/diesels.

    electronic thermostat: this closes on cold engine, makes warm-up much faster and reduces emissions (most emissions are on a cold engine)

    integrated balance shafts into engine block (gear driven)

    small peak power bump to 150 on US spec engine, flatter power curve which means more real world power

    electric VNT actuator instead of vacuum

    water cooled intercooler (no more intercooler icing on jetta/golf/sportwgen) integrated into the intake manifold

    compact catalytic converter and DPF filter...this is the one thing that is really ugly: the cat is right outside of the turbo and exhaust flow hits a flat wall, which forces gas to make 2 90 degree turns into the DPF...this is absolutely horrible for turbo efficiency which means significant losses in power and economy. They could have at least made the piping straighter for less resistance.

    Do you think they did the cat/DPF routing that way for cost reasons?

    I want to know if they added the balance shafts so they could axe the DMF :)

    Not just cost but also space. That shape so close to the turbo is truly horrendous for turbo efficiency.

    DMF will still be there just like on the CBEA engines. It was removed from CJAA engines, no idea why. Nobody seems to notice anyways.

    Talk about over-engineering... gives me a headache... I think I'll look for a Model "T" with air conditioning...

    ... putting them really close gets them up to temperature more quickly, which means lower emissions sooner. A hotter DPF might not need regen cycles as often.

    lets hope they bring the higher output version for the a3 sedan!!
