I would have advised a variable displacement ATF pump within the transaxle to supply pressure for both functions. The newest Porsche 911 engine uses an electric pump for engine internal lubrication to avoid the HUGE level of overpumping with a standard gear type pump at high engine RPM, 20HP gain...(?). |

Replying to: waltchan (Oct 30, 2008 7:09 pm) If you are really concerned with handling, I suggest looking at other vehicles besides Toyota. I don't drive sports cars, but rather 4-door midsizers, but the Toyota's combo of a brake pedal with all the confidence-inspiring feel of mirangue and uncommunicative truck-like steering makes for a very unsecure feeling when maneuvering, to me. Even the SE suffers from numbness. I'm not expecting it, but I'm hopeful that this is improved for 2010.

Replying to: walterkoh (Nov 06, 2008 11:45 pm) While I don't have any pic, my prediction is that it will not be as good as the current version. Leave it for Toyota -- every mid-cycle refresh must be worse than the first version, so it looks like an afterthought. If you remember the last Camry redesign (I think it was 2005) you'll know what I mean. Same for other models, like Sienna, etc. The new refreshed 2010 Ford Fusion, on the other hand, seems to be much more advanced in design, and will be an improvement over the current version -- especially in the front grille section, which will blend beautifully into the front end. |

Replying to: 210delray (Nov 09, 2008 6:29 pm) No one in their right mind would intentionally drive a FWD into an "understearing" circumstance on the public roadbeds in wintertime since recovery is simply a "game of chance". But then there is the subject of unintentional or inadvertent "understearing", in those conditions, what then...??

Replying to: thegraduate (Nov 10, 2008 10:06 am) Wrong, DEAD wrong...!! Assuming equally capable VSC systems the RWD or R/AWD will still remain less hazardous overall, but certainly so in wintertime conditions. Look at how, what most VSC systems do for a vehicle that is understearing. On the assumption that the front wheels have no "reserve" traction they dethrottle the engine and apply braking to the rear wheels, hopefully remaining with some "reserve" traction. Some of newer vehicles with electric power stearing will even apply a counter-stearing force to the stearing wheel against your stearing control input. With over-stearing it is presumed that some reserve traction remains at the front so differential braking is used at the front to create a "moment" counter to the over-stearing direction. But in a rather strange way it may be that you are correct. Since wheelspin/slip due to engine torque is so potentially hazardous in a FWD or F/AWD the VSC/TC systems will be inordinately QUICK, in comparison to RWD or R/AWD(***), to dethrottle the engine the very INSTANT wheelspin/slip is detected. The result.....?? Increased SAFETY of FWD and F/AWD since fewer FWD and F/AWD owners will venture out once they initially encounter TC activation. *** Since the potential for loss of directional control isn't as great for RWD or R/AWD vehicles many TC systems delay dethrottling the engine for several hundred milliseconds once wheelspin/slips develops due to engine torque. If the driver doesn't respond fairly quickly by feathering the throttle then TC will then dethrottle the engine. |
