Article comments for First Drive: 2008 Chevrolet Tahoe Two-Mode Hybrid - Two-mode hybrids aren't exactly new. GM has had the two-mode hybrid system working in transit buses since 2003. Today, about 700 of those buses are operating in 60 cities in North America and have just been introduced in Europe. (more)
Follow-Up Test: 2008 Chevrolet Tahoe Hybrid - Bottom Line: It's better, but whether it's $9,100 better is up to you. (more)

Replying to: ledfoot1 (May 12, 2007 1:01 pm)  I'm a bit disappointed at GM for making the dual hybrid expensive and making these SUVs as a "rich man's green mobile". It should be affordable to all. This is where the goverment should step in and pass legeslation for substancial tax breaks. So far our goverment has done little so far on this.  This new H-Yukon is nice and so far its in the top my list for a new vehicle at the end of the year. We'll see, price will play s role on this. They better be dealing!!!

The 2008 VW Jetta will have a clean diesel that requires no special maintenance or additives of any sort. It is certified for sale in all 50 states, you can bet there will be a line of people at the VW dealers in CA. It will be available 1 or 2 years before Honda's and everyone elses. So apparently Honda doesn't have a monopoly on new technology...maybe they are actually licensing the VW technology! Anyways, the point is that tech wise the Japanese companies aren't always first or best...but unfortunately everyone's been brainwashed to think that way. I for one am impressed with GM's new 2 mode hybrid system. In the long run I'm sure we'll eventually see plug-in diesel hybrids running on domestically grown biofuels getting some ridiculously high mpg that makes all this look like the stone ages. Until then, this is real progress by a domestic company, and as an American citizen I can be happy with that!

The picture of the Yukon in front of the wind-mills (to imply that it is eco-friendly) makes about as much sense as putting an Exxon tanker (with a gaping hole in the side) in front of snow capped mountains in Alaska. The only reason GM is putting its Hybrid technology in it's SU-Blunders is to convince people that they're not SO bad and you dont have to feel HORRIBLE for ruining the air your kids will breath in the future, just maybe a teeny bit bad.

See this web page: Honda's Clean diesel engine So Honda is not "licensing" anyone else'e technology. That diesel engine and clean exhaust system has won international awards since it's invention, and even set some world records: 92 Imperial MPG and 19 world records

Replying to: gmcbob (May 12, 2007 8:19 am) Yes, I read what the GM Publicists said about the system. I also know what they described; a similar design to the HSD. BTW, I think there is a tremendous amount of difference in implementation between a bus and a car. Completely different transmission issues, for one thing. |

Replying to: carchatter1 (May 13, 2007 9:37 pm) So far as I know, only Honda has a system to remove NOx that doesn't require maintenance at around 50K. So far CARB has been reluctant to approve a system like VWs for fear that the owner will not do the maintenance. Mercedes also has a similar system ready for production (or maybe even in production in Europe). I would certainly be interested in a URL that described the VW system that doesn't require NOx additives at ~50K maintenance. Do you have a URL? Did you mean to say it is expected to be certified for all 50 states; I have seen nothing that says any diesel car is CARB certified, and it would be big news here in CA.

Replying to: galvang (May 13, 2007 7:41 pm) Personally, I definitely do not think that the government should be involved in making these hybrids cost-effective for consumers. Sure, current hybrid technology represents an important step towards technology that will actually be beneficial in an economical and ecological sense. Unfortunately, we are however far from that point, costs in manufacturing these systems and their need for polluting resources easily negates the slight efficiency improvement they give. Having government step in and create an imbalanced playing field for a technology that is still in it's infancy would do more harm than good. If you want to buy a hybrid vehicle for the purpose of saving money or benefiting the environment you need to pay to full cost of the technology so that you can make an informed decision whether your purchase would actually achieve that goal. |

Replying to: stevedebi (May 14, 2007 11:11 am) Amid the looming hordes of European luxury automakers planning a North American compression-ignition invasion in the next couple years, humble Volkswagen has announced its plans to return the Jetta TDI to the diesel dogpile in the spring of 2008. Powered by a new 2.0-liter four-cylinder making 140 hp and 236 lb-ft of torque, and either a six-speed manual or DSG automated manual transmission, the 2008 Jetta TDI will be cleared for sale in all fifty states. Some of the earlier diesels to make it to our shores over the next few years will only be available in 45 states; California, Maine, Massachusetts, New York, and Vermont have all adopted stricter emissions regulations for diesels that bar some vehicles from entry. Using technology developed under the BlueTec cooperative formed by Mercedes-Benz and Volkswagen, the Jetta TDI will slip by these stricter regulations without resorting to a urea-based exhaust treatment, as many BlueTec labeled models will. Volkswagen’s Jetta TDI will manage without a urea injection system by using a NOx-storage catalyst. Like the particulate filters in place on this car as well as other diesels, this catalyst is basically a trap that temporarily holds the offensive emissions. Periodically, the engine will switch to an air-fuel mixture that will burn off the material in the traps VW knows about emissions, I do believe that VW offers more PZEV models than Honda or Toyota. I think if Honda had theirs ready for 50 state sale they would have it on the boat headed over. Now if GM would just offer a diesel instead of messing with hybrids they could sell some cars that make money.

Replying to: gagrice (May 14, 2007 12:34 pm) Ford, Chevy, VW, and Subaru all have 3 PZEV rated cars for the 2007 model year. Honda and Toyota one each (hybrids excluded.) |

Replying to: ledfoot1 (May 14, 2007 11:44 am) Our legeslators should step in and help invest towards these new technologies not just for consumers but also for the auto MFGrs. We need to move quickly. How else to move quickly buy giving tax breaks to auto MFGrs and consumers such that more of this technology can be utilized.
