back in mid-March that GM had begun early
production on its Chevrolet Tahoe and GMC Yukon full-size hybrid SUVs. The
dual-mode hybrid system, which GM says is superior to Toyota’s single-mode Hybrid Synergy
Drive, uses mode one for city driving and mode two for highway driving.
GM's dual-mode hybrid system can accomplish all the feats of
the Toyota system -- internal combustion engine (ICE) turned off while idle,
electric-only propulsion at low speeds, electric/ICE propulsion during heavy
acceleration and regenerative braking -- but also adds the ability to improve
highway fuel economy by using two electric motors, two continuously variable
transmission (CVT) modes along with a four-speed automatic transmission and
In addition, all of the electric motor mechanicals are
housed within the transmission, so no additional space needs to be occupied for
Variants of the dual-mode hybrid system will be used in vehicles from Chrysler and BMW.
GM's current ICE-only Tahoes and Yukons are rated at
14MPG/20MPG for 2WD models and 14MPG/19MPG for 4WD models. Today, we’ve learned
that the use of the dual-mode hybrid system boosts those figures to 21MPG/22MPG
and 20MPG/20MPG respectively under the EPA’s new testing methodology.
Those are pretty impressive number for a 322 HP/367 lb-ft
vehicle that is approaching 6,000 pounds -- especially the city numbers.
Despite added complexity added by the dual-mode hybrid system, the two SUVs can
still feature a 6,200 pound towing capacity.
According to Autoblog,
GM was able to offset the weight gain of the electric motors and batteries by
using aluminum for various body panels, lighter wheels, and thinner seats. The
system also doesn't take away from passenger space as the battery pack is
located under the second-row seats.
There is no official pricing available for the hybrid Tahoes
and Yukons, but expect for pricing to start in the mid-$40k range.
quote: Personally, you cannot beat the reliability & performance of Honda (Acura) & Toyota (Lexus). I would rather buy a Toyota Sequoia than a Yukon - because I know ill get my long term moneys worth.
quote: With it being something as serious and important as the engine you'd think they'd at least take a look into, by testing engines and looking into the broken ones, and say what they found, but they don't, to my knowledge.
quote: They do not, however, make these defects publicly known, and nor do their dealerships inform you about them when you bring in your vehicle for other service. I suspect other OEMs do the same.
quote: They will easily put up 200,000 barring the hands of a crazy teenage driver.
quote: Hmm, guess that's a non-issue now that Chrysler started that lifetime powertrain warranty on all of their vehicles, go figure...
quote: "I want a car that does need a 5/50 warranty."
quote: Because I drive one very conservatively, and the other like a bat out of hell.
quote: Either fossils aren't harming the planet, or they are. If they aren't, then people should be able to drive what they want. If they are, then your level of harm is based off how much gas you actually burn, not your choice of vehicle.
quote: Conservative: Favoring traditional views and values; tending to oppose change.
quote: 1. Gas taxes, at least in the US, are not designed to punish "overconsumption" or "inefficiency."
quote: Considering the environmental impact, what is important is the total spent, not the efficiency with which it is used.
quote: But do they work that way?
quote: Everything is a tradeoff. We could minimize environmental impact by stopping the entire economy and have everyone stay home.
quote: Who's really being the troll here?
quote: Which ever used the gas less efficiently, which is why gas taxes hit the driver who gets 10mpg twice as hard as the driver who gets 20mpg, as it should be.
quote: They are mainly designed to pay for road repairs and upgrades.
quote: The environment doesn't give a damn how worthwhile pollution is to humans.
quote: What's worse for the environment, that tank driven 2 miles/wk to church and back, or a car driven 1,000 miles/wk?
quote: Although your example is rather ridiculous, let's use it.
quote: What's more evil, an SUV owner who burns 10 gallons of gas/week, or an Accord owner who burns 20?
quote: If you have a business and need a truck then so be it.
quote: From each according to his ability, to each according to his needs!
quote: So by your definition a Conservative is for "waste"
quote: The point is that people are free to achieve the level of wealth they want and are free to use their wealth in a way that makes sense to them.
quote: I'd really like to see the statistics to back up that sweeping statement.
quote: SUVs should not be classified as pick ups just so they get more lax emission standards either.
quote: We need to be told that we don't need crap. 500HP, that'd never be used. I agree that it's our choice to pick what we want, but our choices should be a little more limited when it comes to cars and such. I'm sure that the people who wouldn't be able to buy a Hummer or Tahoe anymore would get along just fine in something like an Element or some small SUV.
quote: So which makes more sense?1. 40k for a "large" SUV hybrid that gets 20mpg2. 20k for a "medium" SUV that gets 20mpgWhich is more wastefull?
quote: If they both get the same MPG, than neither is more wasteful in terms of fuel economy.
quote: Why do we need to drive these beasts?
quote: I can do anything I want and I do not care how my actions impact others
quote: 1. Joe buys flashy new Hummer. The increased car payment, insurance, and reduced MPG means he drives much less overall, dropping many weekend and nonessential trips. End result-- his total gas consumption declines.
quote: we need to pass some real laws that actually limit the allowed HP on vehicles.
quote: Why can't "all" sides just give a little?
quote: Had the US gone crazy?
quote: Because there's nothing like that offered by anyone.
quote: Predator offers many options such as performance upgrades boasting up to 800 hp and fuel economy upgrades which can top out your economy in the low 30 mpg range.
quote: Not that liberals are so much better, but they never impeached Bush for his lies.
quote: Liberals stop whining about Bush in Iraq
quote: Never completed the process of impeachment for Clinton's,
quote: I said "never completed" as a way to suggest its logical desireable conclusion: removal from office.
quote: So people can also use "never completed" for draft dodger Cheney?
quote: ...and tax tax
quote: middle class extinction tax
quote: Its 2007 my friend, the new word for Minivan is SUV.
quote: Why is a vehicle any different? Why because the TV ads tell us we need a new car :)
quote: "When was the past time you replaced your oven, dishwasher or other household appliance before it wore out?Why is a vehicle any different?"
quote: According to Consumer Reports, the industry average for vehicles only one year old is 19 problems/100 cars. For 3-year old models, that number rises to 55 problems/100 vehicles. Per year. For a vehicle more than 5 years old, the rate is double that again.
quote: Even when you look at reliability figures within a brand, newer cars are more reliable than older ones.
quote: Sorry, but I won't let my wife and kids drive cars more than 4-5 years old. While it will probably last much longer than that, I just don't want to take the risk.
quote: So what does your anecdote prove - that older cars are more reliable than newer cars?
quote: Another thing that these companies should do to improve efficiency is to reduce the weight of their vehicles. Discard the heavy and expensive battery systems with lightweight capacitors. Build more of the vehicle out of carbon fiber.
quote: Aluminum does not get along well with steel when placed in same assembly. You get galvanic corrosion working on the aluminum. Add to that aluminum is notoriously difficult to paint.
