If you're in no hurry, might as well wait for direct injection, right?
 
And how long a wait is that apt to be?

Looking like '09 at the earliest, so perhaps MY 2010... the original news stories are no longer online (?!) but the post can be read at this link.
 
If their MPG improves enough w/DI, I wonder if that will discourage SOA from bringing diesel models to the US, since they could, hypothetically, be arriving around the same time.

Here's the full scoop.
 
She drives a 2002 Legacy L wagon 5 speed now. Perfectly reliable but a little bland. We liked our '98 Forester more. We have a 7/100 warranty and it's been flawless for the past several years. We may go the guaranteed trade-in program since 2002 models are eligible and they appraise very high.
 
She commutes in MD/VA beltway traffic, so she wants an automatic this time. We still have a Miata with a manual if she wants to get her kicks once in a while.
 
We have $1100 Subaru Bucks. Next month we will start accumulating more. It caps off at $100 per month, $500 per year. She puts business expenses on the card, so I think we'll get the full $500 for the year in Sept/Oct/Nov/Dec/Jan. By March at the very latest.
 
The timing is perfect, because the 2009 Forester should start arriving right around then. $1600 Subaru Bucks means she can get a nicer model for less.
 
My practical side says get her a Legacy SE sedan, bargain that they are now. The catch is with auto it may still be boring, and we're back to square one.
 
I'm thinking LL Bean model because it would have all the bells and whistles and with $1600 off in Subaru Bucks we could easily afford it. Operating costs would be very low, yet Foresters are still fun. We'd still have one AWD in the household to get around.
 
I guess a WRX 5 door meets the same criteria, but she would get one speeding ticket a week, whine about having to use premium fuel, and you can't get leather and a moonroof anyway.
 
I really hope the Forester gets Sportshift and a 5EAT. Imagine the cargo space with that new compact suspension, I bet it's roomier than a Tribeca!

It would more likely be the 2.5i Limited/Premium whatever they call it.
 
I think the new 2.5i is a good deal and is a SERIOUS upgrade over the prior version. Buy it. Can't say the same about the WRX, however.
 
The only downside is the lack of a rear sway bar in the 2.5i, which is pretty easy to fix.

I'm not a technical guru, but could we assume it'd be roughly the same as the increase the '05 Legacy had over previous models, since Impreza is based on the current Legacy now?
 
The torsional or bending rigidity of the Legacy have nothing to do with the rigidity of the Impreza. If anything, I would say the Impreza was stiffer than the Legacy, because the only truly max Performance Subaru, the STI, is based on it.

Perhaps Subaru isn't broadcasting the % increase in torsional rigidity on the 08 WRX because it would counteract its "more mature" image? Such a boast could lead shoppers to assume that it must ride harsher than the previous version.
 
Actually a stiffer structure can allow more compliance into the suspension, without degrading the ride (even though it sounds counterintuitive), since the suspension will not have to work to counteract the un-needed motions emanating from the non-stiff structure and can work toward improving the handling, without a ride penalty. Most Germanic products including BMW, Mercedes, Audi etc build maximum stiffness into the structure and then introduce whatever compliance needed, into the suspension.
 
Bottomline, a stiffer structure improves handling AND ride. No reason not to broadcast it, unless there has not been any improvement on that score.

With the Impreza now based on the current Legacy chassis, Legacy would not be at least a reflection on the rigidity of the Impreza? (Not trying to sound sarcastic... I've got little mechanical/engineering knowledge. ) Does sharing a chassis have little to do with rigidity?

Sure, the Legacy's rigidity will have some bearing on the rigidity of the new Impreza, since there are some commonalities between the two. The rear suspension is completely different between the Legacy and the new Impreza and so are several of the cross-members in the structure that promote this rigidity.
 
The question is, do you have data that cross-compares the rigidity of the Current pre08-Impreza, with that of the current Legacy ? If not, then does the information matter at all, for the purposes of gauging how much more/less the new Impreza is over the previous version ? I think unless Subaru comes out and states what those numbers are, we would not know. During the last Gen Impreza introduction, I believe they were front-and-center in stating that the Impreza was over a 100% more rigid that the prior Impreza but this time around - silence !
 
Every single manufacturer (including Subaru) announces the improvement in rigidity when a new Generation product is announced but this time around, I don't see any such data coming from Subaru. Why ? Has the rigidity slipped while trying to increase the size while reducing the weight ?

Yes, it would, though scaled down the same platform would actually be stiffer, since there is less wheelbase and track to flex.
 
Rear sway bar is easy indeed, I put a bigger one on my Forester for $78.

My thinking was that we do have the numbers from when the Legacy changed from previous chassis to current chassis, and now Impreza is making that same change, so I thought the Legacy numbers might at least give us a ballpark idea. Specific numbers? Nope... certainly don't have those. Stats from Subaru often seem quite hard to come by.
