(cross-posted to 4WD & AWD systems explained) "it looks like Toyota has given the Trail Grade 4Runner as much four-wheel-drive capability as anything else sold in the U.S, giving Toyota the widest and deepest range of serious 4x4s (FJ, 4Runner, Land Cruiser) in the industry." Is the 2010 4Runner Trail Grade the Best 4x4 Package Sold in the U.S.? (Straightline)

Replying to: steve_ (Sep 24, 2009 2:04 pm) What this means is that here in the Northeast, when roads go from dry to wet to snow covered and back in just a few hundred yards, you can't use 4WD in the SR5 and Trail Editions. Not good, a big step backwards from the 4th Generation, and a huge disappointment. Steve, I hope you will ask the author of that article to contact Toyota to clarify that the Torsen center diff is not available on the SR5 and Trail editions, and then have him clarify the article explaining the implications. As it is, the article is very misleading.

The new 4Runner is also equipped with a stronger rear differential over the previous model, thanks to a gear ring that has increased in size from 7.87 to 8.18 inches. To enhance grip, the A-TRAC system is now standard equipment on all 4x4 models. The system can distribute driving force to any one wheel in contact with the ground, making terrain irregularities and slippery patches transparent to the driver. An electronic-locking rear differential is standard on the Trail grade. Axles house 3.73 gears, or 4.56:1 with the 2.7-liter engine and the differential housings have improved seals for better resistance to mud and water. Toyota’s Crawl Control (CRAWL) feature is standard on the Trail grade. CRAWL is an adjustable electro-mechanical system that can be tuned to match the terrain by selecting any of five speed levels. The system maintains an appropriate speed that keeps the vehicle under control and minimizes the load on drivetrain and suspension components. The CRAWL feature helps make traversing difficult terrain easier and safer. With the transfer case shifted into low range, Crawl Control regulates engine speed and output (along with braking force), to propel the vehicle forward or in reverse at one of the five low-speed settings. This allows the driver to maintain focus while steering over very rough level ground or steep grades, without having to also modulate the throttle, or brake, pedals. The Trail grade also features a Multi-Terrain Select system which allows the 4x4 operator to dial in wheel slip control to match the terrain. In loose terrain such as mud and sand, more-than-normal wheel slip is permitted, allowing wheel-spin to work in the vehicle’s favor. On bumpy moguls, or solid rock, wheel slip is minimized and the system acts more like a limited slip. The Mogul setting is for any extremely uneven terrain, such as V-ditches, slopes, and ridges, uphill or down." |

Replying to: steve_ (Sep 25, 2009 8:55 am) I'm curious to see what the story is here. Yup, I understand that. I, too, am curious to see what the story is here. But from what I've seen, in the Canadian market all trim lines get the Torsen center diff, while in the US only the Limited trim gets the Torsen center diff. I hope that I'm wrong and your editor is right. But I'd really like to see some clarification from Toyota.
