    The Saturn VUE Two-Mode PHEV-10 turns into the Buick “xxxxxxxxx” Two-Mode PHEV-10.

    The new Buick compact crossover will debut with GM's advanced plug-in hybrid propulsion system in 2011, potentially doubling the fuel economy of comparable-sized SUVs on short trips.

    GM’s new management team has changed the Volt’s previous acronym E-REV (Extended-range electric vehicles) back to the industries commonly held nomenclature, the PHEV.

    PHEV technology will be introduced in a new Buick crossover vehicle in 2011, Tom Stephens, GM vice chairman of product development, announced during a Management Briefing Seminar in Traverse City, MI today.

    The yet-to-be-named Buick crossover will launch in late 2010 offering a family of semi fuel-efficient direct-injected gasoline engines, followed in 2011 by the PHEV variant.

    "Buick has always been at the forefront of new technology, so it is only fitting that the brand should debut our new plug-in hybrid technology in a beautiful new crossover," said Stephens. "This will firmly put Buick, and GM, front and center in the advanced technology game."

    The new five-passenger crossover will build on the success of the Buick Enclave, offering the brand's finely crafted execution and premium driving experience in a fuel-efficient package.

    "Some customers who have been drawn to the Enclave were looking for something a little smaller, but they didn't want to give up craftsmanship or a quiet ride to get there," said Susan Docherty, general manager of Buick-Pontiac-GMC. "We believe this new Buick will excite those customers, and will continue to broaden the appeal of the brand."

    The Buick crossover will be powered by an Ecotec 2.4L direct-injected four-cylinder engine with an optional 3.0L direct-injected V-6, and is expected to deliver 30 miles per gallon or more on the highway. Final fuel economy estimates, as well as additional vehicle details such as name and pricing, will be announced later.

    PHEV

    The Buick plug-in hybrid is expected to be the first commercially available plug-in hybrid SUV produced by a major automaker.

    The Buick PHEV has the potential to achieve double the fuel economy of comparably-sized SUVs on short trips. This significant boost is achieved by combining a modified version of GM's proven 2-Mode Hybrid system with advanced lithium-ion battery cells and charging technology developed for GM's Voltec system, which will debut in the Chevrolet Volt extended-range electric vehicle in late 2010.

    "LG Chem - the supplier of our battery cells for the Volt - has also been selected to supply the Li-Ion cells for the new Buick plug-in hybrid, and its Troy, Mich.-based subsidiary Compact Power will supply the pack," Stephens said.

    The Buick PHEV will use the same manganese-spinel based chemistry and polymer battery cells as the Volt. An 8 kWh pack - containing half the energy of the Volt’s pack - will be packaged in a rectangular-shaped box under the cargo floor.

    The Li-Ion battery can be fully recharged in four to five hours by connecting the vehicle to any standard 110V household electrical outlet. By recharging rather than refueling, the Buick plug-in hybrid significantly improves fuel economy and reduces petroleum use. In early testing, the plug-in hybrid is capable of electric-only propulsion for more than 10 miles at low speeds.

    On the road, GM's 2-Mode plug-in hybrid system can use any combination of electric or gasoline engine power to move the vehicle, depending on the driving conditions. This differs from GM's Voltec technology, which provides the Volt with up to 40 miles of emissions- and petroleum-free electric-only propulsion, and an overall range of more than 300 miles with its flex-fuel engine-generator.

    In addition to the Li-Ion pack, the Buick plug-in hybrid's powertrain features two powerful electric motors, sophisticated electronic controls and battery management systems and an efficient direct-injected 3.6L V-6 engine.

    The battery for a new 2011 Buick hybrid crossover vehicle is prepared for testing at the General Motors Tech Center in Warren, Michigan Wednesday. The Buick plug-in hybrid will use the same advanced lithium-ion battery chemistry as the Chevrolet Volt but will be just half the size at 8 kWh containing half the energy and will be packaged in a rectangular-shaped box under the cargo floor. The vehicle is expected to be the first commercially available plug-in hybrid SUV produced by a major automaker.

    I read it to say they are reserving EREV for the Volt-style engine/generator range extension technology, while using the standard PHEV term for their 2-mode plug-in.

    Why on earth would it need a 3.6L V6? That ensures highway FE will JUST reach the 30 mpg they state, and even that is a miracle.

    This promises to be one of the more complex and tightly packed cars ever.

    I guess the new management is more enthusiastic about a PHEV-10 than the old bunch that was stuck on 40 or bust?

    Hi Ksstathead:

    ___The 3.6L in the Vue Two-Mode was going to produce just 27 to 28 mpgUS on the highway and it appears that GM is simply changing the brand the vehicle will go into is all. And taking its launch out another year or two???

    ___The 2.4L Ecotec is the one Maxxmpg is excited about but with a 31/32 mpg US highway number along with a 21 - 24 city number, it still sucks fuel down like an ornery old drunk :(

    ___Good Luck

    I wouldn't say I was excited about the 2.4L Ecotec, but it is the best they have at this time for squeezing the FE out of these porky cute-utes. The EPA numbers of these little 4-banger Theta jeeps - comparing gas-only models - meet or beat the competition in this arena.

    Here's how the ornery old drunks run up their tabs at the pub...
    2010 Equinox 2.4L 6AT FWD - 22/32
    2010 Ford Escape 2.5L 6AT FWD - 22/28
    2009 Toyota RAV4 2.4L 4AT FWD - 22/28
    2009 Honda CRV 2.4L 5AT FWD - 20/27
    2009 Hyundai Tucson - 2.0L 4AT FWD - 20/25
    2010 Kia Sportage - 2.0L 4AT FWD - 20/25
    ...The Equinox beats them all.

    Even though it sips compared to the Japanese/Korean gas guzzlers, it is still frustrating to see them selling a "small" utility vehicle that weighs close to two tons, with 180-280hp on tap, with about the same interior & cargo space as the Prius III. Why bother with any of them when the P-III is the same price?

    People are told they need something that looks like an SUV because of the image. And they see "hybrid" and think it's greener than other vehicles.
