Subaru.ca says it's 60/40 but can go to 50/50 on demand. It's possible U.S. models are different.
http://www.subaru.ca/WebPage.aspx?We...&WebSiteID=282 BTW, did anybody else notice the paddles work in 'D' mode? I guess if you're not happy with the CVTs ratio selection you can force it. It seems to switch back after a while. |

Yeah the paddles do work in D mode. It mentions that in the manual too. Nice for when you want to quickly go to manual to pass a car or something. Also today I noticed, I had to pass a tractor and I hit 5000rpm, when I was finished and got back into the right lane I let off the gas completely and it just stayed at 5000rpm and was engine braking big time. I had to get on the gas again to get back up to speed, lol. The CVT behavior is weird. |

Regarding Subaru's AWD stratagies: http://www.subaruoutback.org/forums/...anation-2.html
I found another great thread, but didn't save the link, where the Imp's CVT AWD system was discussed. It's supposedly 90:10 in normal driving, but varies *continuously* depending on throttle position, 'gear', cornering forces, etc. It's controlled by a clutch pack. |

The paddles will hold a downshift for a considerable distance, but upshifts 'disappear' in just a few seconds, in D mode. They'd be alot more useful if they held the 'gear' for 15-25 seconds. I use the paddles so that I can use 1/2 throttle, or more, at low revs, to let the engine lug while getting good MPG and good accel. In D mode, the system will go back to D, and the engine will rev 4000+ before the car has accelerated enough to catch the next gear.

And from here: http://www.subaru.ca/WebPage.aspx?We...ebSiteID=282#1
For instant, seamless response to changing conditions, Outback 2.5i models are available with the new LineartronicT CVT (Continuously Variable Transmission). This production-car first - a CVT longitudinally paired with AWD that uses a chain instead of a belt - allows for a near infinite selection of gear ratios, keeping the engine in the most favourable rpm range at all times. This advanced transmission is mated to a multi-plate transfer clutch AWD system that maintains a 60/40 torque split (front/rear) for more predictable handling and automatically adjusts up to 50/50 split under hard acceleration or when conditions warrant. The Lineartronic CVTT is also specifically tuned to provide a more natural feel than other designs for instant response on demand with minimal application of the accelerator pedal. Paddle shifters also provide a 6-step manual mode for quick response on demand. Although it's on the OB page. |

interesting, tried to replicate this tonight, but only hit 4000rpm and it quickly went back down without any engine breaking...but i'll try to explore it in other situations.

Any new findings on disabling VSC on the 5 speed? I'm glad I found out about this before buying one.

They aren't really marketing the 2012 Impreza for its customizable sporty attributes.
Especially if you bought a CVT. Paddle shifters < manual transmission for driver input. Wouldn't it be better to go buy an STI and stop complaining about the lack of ability to customize the driving experience in your impreza ? Last edited by Zeeper; 08-17-2012 at 10:33 AM. |

Can someone please explain the difference in Subaru's AWD implementation in CVT-equipped cars vs. 5MT-equipped cars. I know there is a difference (I think my salesperson said that the CVT implementation is more sophisticated/smarter), but I don't recall the details.

When the computer senses or predicts wheel slip it sends more power to the rear tires as needed, and this happens quickly. The 5spd Impreza uses viscous coupling, a hydraulic transfer system. It is normally 50/50 split power distribution, but if the wheels start to slip the fluid in the viscous coupling case heats up, thickens, and transfers more power between the front and rear to be distributed as needed (wheels that are slipping are stopped by the ABS system so wheels with grip take on the extra power). That's the essence. Some systems like that in the STI are even more advanced and add differentials between the two rear tires to adjust traction and are much more adjustable over all. I like the simplicity of the viscous coupling system, the electronic clutch system can respond quicker to slippage because it can more efficiently transfer power. But if you want to irritate CVT Impreza drivers, just remind them their car is mostly FWD most of the time... |

OK, thanks for the explanation.
Between the AWD systems used in our 2012+ Imprezas (electronically controlled with CVT vs. hydraulic with 5MT), is it possible to say that one is more effective than the other on a snowy/slippery day? |

The electronically controlled system is faster to respond, gives you slightly better mileage (FWD most of the time) and hopefully never fails, because I bet it gets expensive to fix. The "old-school" viscous coupling system has been in use by Subaru since the 1980's, and of course my car is AWD all the time... http://www.awdwiki.com/en/subaru/ How is that for excitement, they added a Subaru XV video showing the AWD system at work...

Yeah, that's what my salesperson said--that the electronically-controlled system was better, but that the hydraulic system was so good that most people will never notice the difference.
I'll be putting snow tires on my car this winter (a lightly used set of Blizzaks I bought on old 16" WRX wheels for cheap). I'm expecting excellent results. |

Hey! 60/40! Subaru Canada says 60/40, I'm in Canada, so it's a 60/40 split. Can it with the damn lies about my AWD system.

Soooo, this was bothering me too the other day, wanted to slide couldn't had to resort to the hand brake.
However I did some digging according to the Forester people the VDC can be killed by removing the abs fuse in the fuse box. http://www.subaruforester.org/vbulle...-thread-82168/ I looked at our fuse box under the hood looks almost Identical to the forester fuse box. May try removing it over the weekend and see what happens, seems to be the same fuse and everything. Also I have a 5spd so may be different for cvt |
