I am finalizing on the Prius and wanted to know whether one should invest the money for Vehicle Stability Control. As in 2007 Prius, it already comes standard with Traction Control. Any thoughts/experience would be appreicated. |

Except in 2 or more ft. of snow, but that's to be expected.  Prius has low ground clearance to minimize wind resistance, and that can mean "plowing snow" if there's enough. Others report going over mountain passes in the western US with no problems.

Replying to: dtener (Mar 18, 2007 2:27 pm) Toyota had to set the traction control to very high sensitivity to protect MG2 (motor generator 2 - the one that moves the vehicle most of the time). If you spin the wheels on ice you could over-spin MG2 and destroy it, so TC protects it. Perhaps a little too aggressively. So far every posting of problems I've read has been on a low speed hill such as a driveway. So if you know you will experience snow or slippery conditions on hills, good snow and ice tires are a "really good idea" (tm). If you're wondering why it over-spins MG2, it's due to the design of the HSD. The rotation speed of the ICE (internal combustion engine), MG2, and wheels depends on the speed of the other two devices. If the engine is off or idling and you spin up the wheels you also spin up MG2 (a lot). This is also why you can't have the engine off above 43 MPH - it will over-spin MG2. There is a good visual example of this on Priuschat you can mess with written in flash, I think. |

Does anyone know where I can find a list of small sedans (2007 models) that have optional Vehicle Stability Control.

| I'd love to hear more about Prius's performance on snow and ice.Often have to come home from work in snowstorms on a dirt road. I now drive a Subaru (with 4 snow tires in winter). It's a great car but not very fuel-efficient. Thanks for any comments. | |

Replying to: lalcott (Jun 07, 2007 2:27 pm) I do use snow tires on the Prius but not on the Outback. We always used the Outback when it's snowing or if we're going on a trip and snow was forecast. We just replaced the second and last Outback with a Hybrid Highlander and will hens forth use that whenever snow threatens. The rest of the time we use the Prius for short and long trips and the Highlander only around town if the Prius is already being used. (I think the Highlander was a mistake but we need a least one 4WD)
