GM Introduces New Malibu; Hybrid Model to Come this Year

At the introduction of the redesigned 2008 Malibu today at the North American International Auto Show, Chevrolet General Manager Ed Peper confirmed that a hybrid version will be introduced with the start of production later this year.

The Malibu hybrid will use the GM Hybrid System already applied in the Saturn VUE Green Line SUV and Saturn Aura Green Line sedan hybrids. The GM Hybrid Belt Alternator Starter (BAS) system in the Green Line vehicles combines an electric motor/generator with a 2.4L Ecotec VVT four-cylinder engine, Hydra-Matic 4T45 four-speed transmission and Cobasys 36V NiMH battery pack. (Earlier post).

The 2008 Malibu.

The non-hybrid models of the new 2008 Malibu offer either a 2.4L Ecotec DOHC four-cylinder engine or a 3.6L DOHC V-6 with variable valve timing (VVT). A six-speed automatic transmission is standard with the V-6 and is offered with the 2.4L four-cylinder—a segment first.

The 2.4L Ecotec DOHC four-cylinder engine is rated at 164 horsepower (122 kW) and delivers an estimated 31 mpg in highway driving. The available 3.6L V-6 VVT is an all-aluminum DOHC engine that uses variable valve technology to produce 252 hp (188 kW) while delivering an estimated 26 mpg in highway driving.

If the Camry hybrid is over $26K, then I think that they need to bring this in at or below $23k to have a chance.

If ever a car needed a makeover, it was the '06 Malibu.
Based on earlier post claim of 25% fuel efficiency, we have a 39mpg hwy / ?? mpg city candidate? Under $25k, this is a good step..

In terms of hybrid technology, this is more of the same but that does not make it a bad thing. On the contrary, mainstreaming hybrids in terms of actual sales volume as opposed to merely market perception is a very worthwhile ambition.

Even basic stop/start functionality and mild boost/recuperation can deliver fuel economy benefits of 5-10% at moderate cost. Of course, it makes little sense to combine this fuel saving feature with a gas-guzzling 3.6L V6. If you care enough to buy a hybrid to begin with, consider choosing the 2.4L engine and spending the difference on something more worthwhile, like an electric bicycle. You really don't need a V6 to go shopping and, out on the highway the hybrid system has no effect on fuel economy.

Rafael Seidl,
They could add CD, to shut down half of the cylinders, under low load (V6-V3). GM V8s already have it, though to accomplish the smooth operation/transition Honda has with their V6 CD system may be a bit of a challenge.


_GM should push to have a BAS version all their models by 2010. This would improve fleet fuel mileage, since some may not opt for the 2mode, but want better than conventional drivetrains. They can market it as "freedom of choice".
_Demonstrate clean and quiet electric generator mode in disaster/blackout prone areas. Do the same when the Tier2Bin5 diesels reach market.

FYI CO2,
Yeah, way too much crome on the front and rear.

I just finished reading a report of an energy analysis of a number of regular and hybrids that covered ALL energy expended in every facet of the vehicles life, from cradle to grave. It showed that hybrid versions are much less energy efficient than their non-hybrid brothers. This is tellingme that hybrids are a fraud that has been sold to a gullible public by automakers and environmentalists eager to rip off same. Plug-in hybrids that are serial would be cars that would be energy efficient, in addition to freeing our country from dependence on foreign oil. They should be supported.
I call on everyone concerned about our energy situation to boycott non-plug-in hybrids. They have acheived nothing other than depleting our wallets and making
some ignorant environmentalists self satisfied.

If you're talking about that ridiculous CNW study, that's already been debunked. A Prius does take more energy to build than a regular sedan but that deficit quickly disappears when you start to drive the cars.

So unless you buy cars and never drive them...

The Vue Greenline has the 2.4l with BAS and gets 27/32 and weighs about the same. Considering the Malibu is more streamlined than the Vue, the highway might be higher, but they quote 31. Since all the EPA numbers will be revised for more real world conditions, the numbers will to down.

Kent,

There is the efficiency of consciousness to consider which causes a consumer to think higher MPG, lower GHG products in the first place. To say that manufacturing costs zero out the benefit of moving to renewable energy is old fashioned spin accounting from the 1940s.

Patrick

Well, consumers who want a vehicle which uses less foreign oil would do just fine to buy a hybrid. We get very little power (for manufacturing or otherwise) from oil.

fyi CO2

Kent- better find a stronger leg to stand on before you stumble on this blog and call for a boycott; PS- Al Gore is not living in Venezuela.

I used to hear the same thing about PV solar panels, that they took more energy to make than they could ever produce. After someone added up all the processes and the energy involved, it turns out the average PV panel takes around 3 years of energy to produce and the average panel lasts 30 years. I would like to see the detailed listing and calculations on something like the Prius before I make up my mind on this issue.

Too little, too late.

By 2009 and 2010 Toyota/Honda hybrids will get 100MPG.

GM has lost the hybrid battle.

Ron Fischer

Compare GM's concept cars with the roadmap above showing what they're actually going to sell to the public. Bit of a gap there. Perhaps closing it is next on their agenda?

Also: on the CNW hybrid study the flaw there (from memory) was overestimating second and third order development costs then using very low production numbers to amortinze them.

SJC

I just saw a story on the GM Volt on ABC News. They said that GM is waiting for 3-4 years for the batteries to come down 10 to 1 in cost, but industry analysts said it would take more like 10 years. They also said at present battery costs, the Volt would sell for $200k. I don't believe any of that, but thought I would pass it along.
