What's good for GM
Star-Telegram Once again, Arlington has decided to test an old economic premise long advocated by those transit philosophers often described as auto monopolists: What's good for General Motors is good for America. Arlington favors what's good for America, of course, but in this case the city's elected officials also hope that nearly $6 million worth of tax breaks authorized this week will work out to be most excellent for … well, Arlington. Without actually promising to build the next generation of sport utility vehicles at the Arlington facility, GM is planning to invest $170 million in improvements to the local plant. It's on that investment that the big automaker wanted a property tax break over the next 10 years. The plant manufactures the Chevrolet Suburban and Tahoe, the GMC Yukon and Yukon XL, and the Cadillac Escalade. Those are not, unfortunately, the most fuel-miserly of vehicles, and their popularity could be endangered if gasoline prices continue to escalate. So there's some risk involved. On the other hand, GM plans to introduce much more fuel-efficient hybrid versions of SUVs that combine big-haul capabilities with the gas mileage ratings of today's midsize sedans. If the new technology catches on as expected, the long-term benefits that the GM plant provides to the region could be tremendous. Full Article Here

And everyone who bought a hybrid car is now pissed off royally since their gas milage can be easily beaten by a conventional car of much lower cost, and their EPA numbers are far overblown.

Where are the hybrids from Mercedes, Chrysler, Mazda, BMW, Mitsubishi, etc. At least GM is bringing some out. You think a hybrid Aveo makes more sense than a hybrid Silverado? Where can the most impact be made? Other than the Toyota PR people, who else has confirmed that Toyota is making a profit on "each and everyone" of their hybrids? GM took the leadership role in electric cars some years ago and they lost $1 billion on it. Did they get one bit of credit for their efforts there? No. They got no credit when they offered the EV1 and they were criticized for when they discontinued it. Mark |

I really don't get GMs alternative fuels strategy. They jumped into all-electric when everyone else knew it was poing nowhere, are mostly ignoring hybrids whereas all the other big players are getting in big time, and are pushing near-future hydrogen when everyone else thinks it's decades off. Could this be because GM is afraid of actually making a change, and figures it can get the PR value out of electric or hydrogen without the cost and effort of putting real, practical cars into full production? |

Not sure about the others tho'. Nissan liscensed Toyota's suite of patents, but I'm not sure when their first vehicle will be out. DCX seems to be jumping big into diesels as their big fuel-saving technology. Still when even Honda (which is one of the smallest independent automakers) can make their own hybrids in signifigant numbers there's no excuse for GM (the world's #1 automaker) not to. |

I think the law of conservation of energy is the real problem behind hybrids. They take one step forward and two steps back. |

While a 10-year old 3-cylinder Geo Metro MAY get "rougly [sic] the same gas mileage as a modern Toyota Prius," the Prius is a MID-SIZED car while the Metro was measured to be a MINICOMPACT (three size classes smaller) by the EPA. The Metro was also CONSIDERABLY slower than today's Prius. And five people can comfortably travel in a Prius (trye getting FOUR people to be comfortable in the Metro).
EPA's quotes for hybrids is a little optimistic, but then again so are ALL EPA estimates. The fact is: the Prius gets better gas mileage in the real world than ANY mid-sized car currently on the market in the US. It also tops any COMPACT non-hybrid in gas mileage. I've driven the Prius (old and new) as well as the Insight (haven't driven the Civic Hybrid yet) and they get better mileage than anything offered today...in real-world gas mileage. As was stated earlier, GM's "hybrid" trucks aren't really hybrids. Ford has REAL hybrids coming (with the help of Toyota). Dodge has REAL hybrids coming. Toyota has them...Honda has them...Nissan's got them coming. And, yes, GM has REAL ones coming, eventually. Hybrids are real vehicles...getting very impressive gas mileage...providing excellent performance...and reducing emissions. Just wait for the performance hybrids that are coming...they'll be truly impressive. |

Dodge has hybrids coming? News to me.
And Ford had no help from Toyota. They liscensed a dozen or so Toyota patents long after the Escape was completed to avoid possible legal trouble. They also filed over a hundred of their own. Of course the media completely misreported the story <_< |

As I mentioned, Hybrids aren't getting very good real-world gas mileage. Although the EPA ratings between the Metro and the Prius are similar, in the real world, the Metro tends to do better. Though the Prius makes 76 horsepower (which is actually pretty weak by today's standards), it's hauling around 2890 lbs. worth of car, giving it a power to weight ratio of 1:38. The Metro's 49 HP 3 banger is in charge of motivating 1621 lbs. of car, giving it a better power to weight ratio of 1:33. On the highway, the Metro is beating the Prius by 7 MPG according to the EPA ratings. And although the Prius is a little bigger than the Metro, the Honda Insight is decidedly smaller...it can only seat 2 people. It's engine is weaker (65 HP), it's EPA score for highway mileage is 2 MPG less than the Metro, and has only slightly better power-to-weight ratio than the Metro (it should, considering it only seats 2).
I really am not all that impressed by hybrids, and I suspect that GM isn't impressed either. |

The gas engine alone in the Prius makes 76 hp and 82 lb/ft (it could make a lot more but it's tuned for economy and is running a atkinson cycle), while the electric motor makes another 67 hp and a whopping 295 lb/ft of torque from zero rpms!!!

And if you live in a Northern state or in Canada where you need to run your heater for half the year, your mileage in the Prius or the Insight suddenly drops. Where heat is a byproduct of a gasoline engine, it's a real drain for batteries to run an electric heater. And thanks to the laws of thermodynamics, those batteries take a lot more energy to charge than they'll put out.
Then there are other "Hidden" expenses. Eventually, batteries need to be replaced. What is the cost associated with that? Your brakes are now regenerative, which adds to the complexity of the vehicle...can you just get new rotors and pads when the brakes wear out? Will the money saved in fuel costs actually pan out in the long run, or is a person better off buying a Diesel VW Golf, which runs on cheaper Diesel fuel and gets 38/46 MPG. Once you consider how much cheaper it is to pump Diesel than it is to pump regular unleaded, you get more miles for your buck with the Diesel Golf than you would with a Prius. And that's using a very old engine design! I'll bet GM will be smart enough to recognize this and start making cars with high efficiency Diesel engine alternatives instead of going with the lame, overdone and overrated Hybrid technology. |

Dodge:
Your information is not the best. Honda gas engines actually run all the time in the hybrids. In the Toyota, it shuts off when you come up to a light and stop moving for a while. Yes, the heater would need the engine, but it's still a very economical engine, even running. As for comparing the Metro to the Prius, you keep forgetting that the Prius actually does make more power when the electric motor kicks in...you forget that the Prius is considerably larger inside...you forget that the Prius is much more refined than the Metro...that the Metro was a 2-door...etc. While power to weight is one way to measure a car's performance potential (again, forgetting the electric motor's additive power), the REAL WORLD shows the Prius to handily out-accelerate a Metro XFi. And there's the excellent gas mileage of the Prius. Stew: Ford did use some Toyota technology in the Escape. And Dodge does have the Ram Truck HEV coming. |

True, hybrids aren't as effecient in the cold: the battery is less effecient and with a full hybrid I suppose the gas engine might be kept on more to power the heater (I don't think it's ever run electrically). Not sure how much the cold hurts tho'.
And what Toyota technology does Ford use? They've sourced a few components from Toyota-owned suppliers but there's nothing unique about that. It's a Ford engine mated to a Ford transmission/electric-motor combo, controlled by Ford computers. |

Although it is really tempting to jump on the hybrid bandwagon, first hand experience has shown me the limitations (and outright media deceit) of the hybrid.
Where I work we have one gentleman who drives a new Prius. He claims to regularly achieve around 45 mpg. He babies his car, loving the fuel-conserving video-game element of it. As such, he is also the car everyone wants to beat out of the parking lot, because he ever-so-slowly accelerates on the onramp (often causing much traffic chaos). I think he could be portrayed as the typical Prius driver. We also have another gentleman who just bought a used Volkswagen Jetta TDI. His real-world mileage is consistently 50.2 mpg. He's usually right with us in trying to pass the fellow in the Prius. The performance/fuel efficiency advantage of the Passat TDI over the Hybrid Prius is never clearer. So Hudson, can you please explain to me where the "excellent performance" of the current hybrid vehicles are being observed. Or do you mean performance of a different sort? Hybrids will be a useful stepping stone in automotive technology, but once you wash away the media-hype and inflated estimates, I don't think that their real-world performance warrants the kudos they are receiving.
