Like other hybrids, the Tahoe and Yukon are equipped with regenerative brakes that capture energy normally wasted during braking and use it to recharge the battery. A new air-conditioning unit requires less power and thus uses less fuel. And Tahoe Hybrid rides on lightweight aluminum wheels with tires that have low rolling resistance. Go ahead and LYAO as you shoot yourself in the foot.

It's not a huge issue but it's there nonetheless. It's one of the reasons I believe that the new Gen 3 next summer will a little lower, wider and longer. |

Lets see this Safecar.gov quote that all CURRENT government ratings are useless. Why are YOU quoting data from the 70's and 80's and saying I'm 30-years behind? They said no such thing in their 2005-2009 Plan, Through the combined efforts of NHTSA, Congress, states, local law enforcement, public safety groups and industry, the nation has made major strides in reducing fatalities and injuries in motor vehicle crashes. An effective way to help consumers enhance the market for safety is to provide them with more comparative vehicle safety information, including crash test ratings and available safety features. Increasingly, consumers are demanding such information and are basing their purchasing decisions on it. So what exactly are you basing your safety assumptions on? The Informed for Life site claimed to use both NHTSA and IIHS government ratings, but in the end, they clearly just picked their own numbers. Are you defending drum brakes as the epitomy of safety? Do all Toyotas come with standard 4-wheel ABS yet? I know in 2005 only the fronts were standard, with others moving to 4-wheel disk/ 4-wheel antilock long before them. The only company I know that is behind the times on safety is Toyota. Even if they fixed the problem, they leave a foul taste in my mouth. Clearly it is useless to argue against the propaganda minister in his own forum. It is clear that you have a predisposition to argue in favor of the Prius in spite of all available evidence.

Replying to: stevedebi (May 21, 2008 12:08 pm) So technically, they are 'lower rolling resistance' because of surface area. Just not tread compound. For those that don't know; traction, breaking, and accident avoidance in general is improved as tread area is increased (so long as the tread is good). At the same time, fuel usage goes down. They are still sacrificing safety in the name of the almighty kthx. bye |

Replying to: bksmith1 (May 21, 2008 12:50 pm) Why would you compare MPG of vehicles of different types? That's where the Outback/Prius conversation started. Then I was responding to a 'mathematical' comparison of the Outback vs. Prius safety, which like you say is bogus to begin with, but on top of that the math was bogus. Then there's those that want you to believe that the government is trying to kill us all with faulty safety data. That the worst thing you could do is trust the NHTSA ratings. Its a conspiracy! I doubt that very much. I think of the Prius as among the least likely vehicles out there to be able to AVOID an accident, let alone survive it. Its as stable as a pig on iceskates, with arthritis in the back feet. Fortunately, the best mileage occurs in the city, where high speed crashes are less likely. And both major Prius wrecks I saw this year were on a 65mph highway. |

Replying to: bigmclargehuge (May 21, 2008 11:09 am) In your quote it talked about the Yukon / Tahoe hybrids. It said nothing about the Prius. That was your own biased interpretation, incorrect BTW. It said '...like other hybrids the Tahoe and Yukon are equipped with regenerative brakes that capture energy normally wasted during braking ....' PERIOD, new subject, IT says nothing about the Prius and LRRT's.

Replying to: bigmclargehuge (May 21, 2008 12:36 pm) 2008 Prius specs, Gen 2, are 185 / 65 R15 or 195 / 55 R16 depending on model Regarding the NHTSA tests there's a long discussion on the website of the 'Enhancements' needed....Here's a sample Eighty-seven percent of MY 06 vehicles received four- or five- stars for the driver. Consequently, the side NCAP ratings are reaching the point of providing little discrimination between vehicles. Since the fleet has changed both in terms of weight and front end characteristics, and since the side impact occupant protection systems have improved over the years, it is necessary to revisit the design of the side test to better reflect what is occurring in the real world when serious injuries result. Approaches to enhancing Side NCAP • The agency can use NCAP to encourage head protection by using the pole test proposed for FMVSS No. 214 until such time as the rule is fully phased-in. This test would continue to measure performance while at the same time indicate to consumers the importance of good head protection devices.16 Some research will be needed to develop a new rating system. Also, since both the ES-2re and SID-IIs dummies were specified for use in the proposed FMVSS No. 214 pole test, a decision will be made on whether one or a combination of these dummies would be used for ratings in the NCAP program. • Research that focuses on the assessment of the injury mechanisms in a fully equipped side impact air bag and window curtain fleet needs to be conducted. The purpose is to evaluate how serious injuries occur in a fleet fully equipped with inflatable head protection and develop test procedures to reflect these impact conditions. The outcome of this research could be used to further raise the level of side impact protection. More research is needed, as outlined below: • A new barrier test protocol. The research will evaluate the side impact crash conditions that generate serious injuries to the occupants of the struck vehicles in the new fleet. This includes examining vehicle orientation at impact, vehicle trajectory at impact (e.g. barrier impact angle), and impact location. • Increase speed. This strategy would potentially address the serious injuries that occur in the 21-25 mph delta-V range. The 21-25 mph delta-V range has the highest number of serious injuries (5,638) in vehicle-to-vehicle side crashes. • Increase barrier weight, change geometry, and/or modify stiffness characteristics. This is an opportunity to refine barrier characteristics as the fleet changes. It is also a chance to evaluate the different MDB characteristics around the world in hopes of developing one common barrier. This strategy could adopt the IIHS barrier or build on previous research to develop other methods. • Use of new dummies, such as WorldSID. Considerable effort by industry and governments has been devoted to development of WorldSID, a new 50th percentile side impact male dummy. NHTSA is evaluating the WorldSID dummy. If development progresses to the stage that it is ready for incorporation into NHTSA’s test dummy regulation (49 CFR Part 572), inclusion in side NCAP would follow. • Develop additional lateral injury criteria. If new dummies are used, the agency would take full advantage of new dummy capabilities to measure additional lateral injuries. If you read the whole discussion you will see that they state that the test criteria were first set up in the late 70's. A few minor adjustments have been made since then but nearly the entire fleet is 4 or 5 star. |

Replying to: kdhspyder (May 21, 2008 3:15 pm) Golly Gee you're only 6-1/2 years out of date!!!!! You do realize that since the Gen2 came out there are no such thing as LRRT's on any of the OEMs. How can you make a post like that based on completely inaccurate data? Pretty soon it will be 2004 and you can bring yourself up to date. In your own words you said "none of the Original Equipment Manufacturers used LRRTs." Incorrect BTW. My only interpretation is that you are easily offended by someone who correctly challenges your own limited knowledge and misinterpretation of reference matierial. PERIOD. new subject.
