    You may be right Colin, but Subaru has a lousy record in terms of selling turbo 4s in their larger cars. Maybe it's been not having the right recipe: no auto option in the LGT, for example; or the premium gas requirement and 3500-mile oil changes that their turbos require. If they can make a turbo 4 that's as easy to live as a non-turbo H6, then their chance of pulling that off is much better.

    However you do raise an interesting point, as there have zero rumors about a next-gen H6. If this new 2.0 DIT is that good, could the H6 be headed for the scrap yard?

    Finally, I'm really curious about their Subaru electric turbo rumor. The word is that much of the turbo's extra plumbing will not be needed with the electric turbo. Yup, real curious about this...

    How is an electric turbo not more closely an electric supercharger?
    Anyway, one would think it would make early compression possible and mitigate much of the turbo lag that most buyers seems to avoid.
    My understanding was that the new Leg turbo acheived that, but never got to drive one, as the local dealership didn't sell one in the past year.

    "How is an electric turbo not more closely an electric supercharger?"

    I've been wondering the same thing.

    I'm more curious about what has changed in the last decade or so to make electric turbo/superchargers actually feasible.

    They hit the aftermarket in the early 2000s and were a complete joke. I believe a few magazines tested them, and were unsurprised when they failed to do much of anything useful.
  • rshollandrsholland Posts: 19,652
    I wasn't aware of that. I thought this was new technology.

    if they actually work I would be quite pleased to call them completely new technology.

    seven year-old discussion on electric superchargers / turbos on nasioc.

    nothing inherently wrong with the idea. HR added a couple leaf blowers to the intake of a rat-rodded Corvette and did picked up some performance. Still, there's no such thing as perpetual energy. If they are used continuously, they will be an energy drain.

    Very true. The idea seems to be space saving and integration (i.e., reduced piping, and ECU control of the turbo unit) without losing so much of the performance gain as a result of increased load on the alternator.

    So, you put a turbo unit in-line with the exhaust that runs a generator (rather than piping to the engine), and then a second electric unit on the engine's intake. The only piping you need is for the intercooler unit; everything else is just wires.

    Once the control of the turbo is electric, you can map it to fill in the weaknesses of the engine's own power curve because you're no longer relying on exhaust pressure to spool the unit. And yet, all that exhaust pressure isn't going to waste either, because it is being used to generate electricity to supplement the car's engine-driven alternator, thereby using energy that is otherwise wasted and keeping more power going to the place you need it: The wheels.

    Generating electricity using a turbine in the exhaust will generate a lot of back-pressure and reduce the efficiency of the engine.

    In the future we'll see a KERS setup. The question is how to store the energy - batteries are heavy and expensive.

    From AN, 5/16/12:

    Subaru said today it will expand its Lafayette, Ind., plant to boost production of the Outback crossover and Legacy sedan and wagon.

    The $75 million, 52,000-square-foot expansion of the plant’s body assembly section is slated to start this summer and will increase the plant’s capacity to 180,000 vehicles during regular shifts, according to Subaru. The current limit is 156,000 units on straight time, the company said.

    The expansion also is expected to create 100 full-time jobs, according to Subaru, a unit of Fuji Heavy Industries Ltd. of Japan.

    The Lafayette plant employs 3,600, with more than 600 jobs added since 2009, Subaru said. It also makes the Tribeca SUV. Another line there produces the Camry sedan for Toyota Motor Corp.

    The expansion confirms plans for more North American capacity, which Fuji signaled during a May 8 press conference in Japan.

    Subaru recently scrapped a plan to build vehicles in China by 2016 and instead will focus on boosting North American output.

    Besides increasing output at its Indiana plant, Subaru may increase North American production with a new vehicle line or even a new factory, Automotive News reported this week.

    In 2011, more than half of Subaru’s vehicles sold in North America were assembled at the Indiana plant, which opened in 1987.

    The plant produced 170,629 vehicles in the 2012 fiscal year, but daily and Saturday overtime shifts were needed to reach that number.

    Another reason why Subaru has upped production in Indiana since 2010 is to counteract foreign exchange rates that hurt profits on imported vehicles.

    Yasuyuki Yoshinaga, president of Fuji Heavy, wants the Indiana plant to build 200,000 vehicles a year by 2014.

    “The expansion of SIA’s capacity is necessary to meet the growing demand for Subaru vehicles in the North American market,” said Tom Easterday, executive vice president of Subaru of Indiana Automotive, in a statement. “The success of the SIA-built Legacy and Outback is the result of innovative design focused on the needs of our customers, a strong reputation for quality and reliability and consistently achieving top safety ratings.”

    Through April, Subaru sold 15,916 Legacys, up 12 percent from the same four months of 2011. Subaru sold 35,608 Outbacks during the first four months, up 2 percent from 2011.

    boost production of the Outback crossover and Legacy sedan and wagon.

    Do they build a Legacy wagon in Indiana for export?
  • rshollandrsholland Posts: 19,652
    Good question. Either they do or it's a typo.

    Any news on new Forester or anything else? Awful quiet here.
  • dcm61dcm61 Posts: 1,432
    New meaning 2013 or ALL new meaning 2014?

    2013 is supposedly a carry over from 2012

    2014 is new body, dash from 2012 Impreza, possibly direct injection on FB25 (or maybe a FB20-DI), CVT.
  • rshollandrsholland Posts: 19,652
    Hope you're right about the DI, but I would think that would debut first on the WRX and/or STI, or even the Legacy and Outback first. My guess is DI will make it's way on to the Forester last; maybe at the next model's mid-cycle refresh.

    Hope I'm wrong. So surprise me Subaru! ;)

    The Forester has been the guinea pig for previous Subaru engine changes.

    Phase II SOHC - introduced 1999 (1 year before Legacy/Outback)
    FB25 - introduced 2011 (2 years before Legacy/Outback)

    Pretty sure I read an internet article (so it must be true :) ), that MY14 (or whatever year for the new design) Forester was getting DI. Also, new WRX was getting FA20-DIT.
  • colin_lcolin_l Posts: 591
    I think the Forester gets engines early because they're made in Japan, rather than Indiana. :)
  • rshollandrsholland Posts: 19,652
    Hope you're right, as they need to get DI here ASAP.
