#697 of 1436 2006 Throttle Response?
May 10, 2006 (9:26 am)
I have a new (600 miles) Forester XT 5 speed, and I've noticed something that MAY be related to the electronic throttle. Trying to maintain a constant but low speed in 1st or 2nd -- say, in a parking lot, driving around in a shopping center with speed bumps and traffic, or approaching a red light from a ways back -- the car tends to buck a bit, as though the engine is being lugged. That's not happening, however, since the rpm's when this happens are too high for that, 1500 to 3000. It happens when I'm applying VERY light pressure on the accelerator, or just after releasing that pressure.
To check on this, I went in to my dealer's service dept. this AM and one of the techs drove around with me for a while. He wasn't sure about it, but thought there was a chance it was a result of a new fancier flywheel Subaru introduced in the 2006, to combat, he said, shudder in acceleration that had been noted on earlier models. If it keeps up, he said to bring it back when the Sub tech rep is at the dealer, which I will do. Anyone else noticed this?
I've had a good deal of experience driving a 2004 FXT and a 2005 Legacy GT (both 5MT), and this problem (if in fact it is a problem) did not occur on either one.

I have noticed a less-linear throttle reponse, ever since the Phase II engines came out, in 1999-2000. But they went to throttle-by-wire since then so it may have changed yet again.

Are you sure? Who sources the diesels in FHI heavy equipment? I would be astounded if the big garbage trucks didn't have Fuji diesels in them.

Diesel fuel is now cheaper than gas where I live.

They may have really big and really small diesels, but where's the 2.0-3.0l ones that would be able to sell here? It'll end up being a clean-sheet design I bet.

Diesel or not, the rest of 'em need bigger fuel tanks, especially the XT. The range is absurd.

The redesign should address that.
For its class, the tank is actually not the smallest, not by a long shot.

yep, on the same page now. But I submit that they DO have experience with diesel engine engineering and fabrication.
But I also bet they bring in some current diesel engine gurus to make something quite modern and efficient. It won't be a cast iron boxer engine.

John, I've read that the new diesels will be boxers, likely aluminum blocks with iron sleeves. Not sure about the heads, though. Obviously any engine configuration other than a boxer would be difficult to integrate into existing Subaru platforms.

Where did you read that? I'm interested in diesels myself and with the intro of low sulphur fuel, it would be more of an enticement. What model year are we talking here?
And how about the extra cost of the diesel engine?
