Mastering the new lingo – parallel vs. series hybrid

chevy-volt-concept-07

Wired.com’s Autotopia blog has a cool post of five auto-related terms that will be dying out soon along with five new terms that we’ll need to become familiar with. You’ll soon be forgetting terms like gas pedal, MPG, throttle, transmission and tachometer. Here’s one of the new ones:

Parallel vs. series hybrid – These terms have so far been relegated to the geeks, but as the industry progresses and hybrids of all stripes become more common, you’ll want to know the difference. They refer to how the gasoline engine and electric motor are configured. A parallel hybrid like the Toyota Prius uses a traditional transmission to couple the gasoline engine and electric motor to the wheels. Such vehicles use internal combustion and electricity to drive the wheels. A series hybrid like the Chevrolet Volt does away with the transmission because the engine drives a generator that takes over when the battery runs down. The electric motor is the only thing driving the wheels. Many see the series hybrid as the “true” hybrid configuration minimizing energy loss due to wasteful idle engine spinning friction.

Also, get ready to hear the following terms as well: Lithium-ion battery, continuous vs. peak power, kilowatt-hour vs. kilowatt and drive-by-wire.

Fiat expanding into China with joint venture

Fiat’s Sergio Marchionne said he needed scale to compete, and now he’s plowing forward in China.

The Fiat Group announced a 50-50 joint venture on Monday with the Guangzhou Automobile Group to make cars and engines for the Chinese market, the latest move by the Italian automaker to expand outside its home market.

The companies said they would build a 173-acre plant in Changsha, in Hunan province, at a cost of more than $556 million, with production to begin by late 2011.

Upon completion of the first phase of development, the venture will have the capacity to make 140,000 cars and 220,000 engines a year.

The companies said capacity at the plant, which will make fuel-efficient, low-emission vehicles, could eventually be increased to 250,000 cars and 300,000 engines a year.

Sergio Marchionne, Fiat’s chief executive, has described the world’s carmakers as being in a struggle for survival, with only those of sufficient scale and efficiency capable of riding out the crisis. Fiat, which had revenue last year of $83 billion, acquired a controlling 20 percent stake in Chrysler Group LLC in June to gain access to the North American market.

The Guangzhou Automobile Group, a state-owned holding company, had 2008 revenue of $16 billion.

The company, which has joint ventures with major partners including Honda Motor Co. and Toyota Motor Corp., said it delivered more than 530,000 cars to customers last year.

Fiat has been looking for a new Chinese partner since it terminated a venture with Nanjing Auto in late 2007. A planned joint venture with Chery Automobile, China’s largest domestic carmaker, was to start production this year, but the project was put on indefinite hold in March.

Marchionne also said that Fiat is still interested in Opel as well.

Tesla sticking with laptop battery cells

Tesla will not make any immediate changes to the battery for it’s new sedan.

Large format battery cells will slowly gain a foothold on the automotive EV market in the coming years. Companies such as LG Chem, A123 Systems, and EnerDel have been hard at work developing the large format automotive specific batteries, but Tesla still insists that the laptop format, as used in their Roadster, is the best thing going right now.

According to Tesla, the laptop battery offers proven performance at an affordable price. With mass production of this type of battery ongoing for several decades now, the technology has advanced beyond that of current large format batteries. As Tesla has indicated, the mass economies that surround laptop batteries have increased competition, driven technological advances, and reduced prices making them perfectly suitable for cars.

Tesla recently received a loan from the federal government, and it will be interesting to see how he battery issue plays out over time.

Tesla Motors, an electric-car company in California that sells a high-end roadster, will use some of $465 million in loans now to build a plant in Southern California to make its new Model S sedan. The rest will be used later for a plant in Northern California to make battery packs and electric drivetrains to be used in other carmakers’ vehicles.

Who Killed the Electric Car?

Bob Westal takes a look at the 2006 documentary:

With a share of General Motors running just a bit above the price of a single Hot Wheels car, this seems like an opportune time to catch-up with this surprisingly upbeat 2006 documentary covering perhaps the worst single piece of corporate strategy in business history. Directed by first-timer Chris Paine, with assists from big-time executive producer Dean Devlin and super-documentarian Alex Gibney, “Who Killed the Electric Car?” starts off as an earnest, L.A.-centric, paean to the efforts of activist drivers to fight GM’s very literal trashing of the all-electric EV-1 — launched in 1996 on a lease-only arrangement after California emissions rules forced auto companies to explore non-polluting vehicles. After spending time with such once-satisfied EV-1 customers as actors Mel Gibson, Tom Hanks, Peter Horton, Alexandra Paul, and comedienne Phyllis Diller, the film switches gears to becomes a far more interesting industrial whodunit, examining the corporate and the political forces that led to the car’s passive-aggressive treatment by GM.

Five Greenest Vehicles at the 2009 Geneva Motor Show

The green revolution is in high gear! Inhabitat covers the Geneva Motor Show and picks its five green favorites: The Infiniti Essence (pictured above), the Chevrolet Spark, the Volkswagon Bluemotion Polo, the Ford losis Max, and the Dacia Duster.

All of them are cool cars, and thiagain demonstrates that the new push for green techology can lead to an explosion of innovation. We do not need to continue our addiction to oil. It’s now just a matter of time, and these cars show that the transition can be fun as well.
