GM's goal is to cut weight by as much as 15 percent to reduce fuel consumption

General Motors (GM) is in the midst of developing an electric vehicle (EV) that can achieve 200 miles of battery-only range.

GM CEO Dan Akerson unveiled the project last week at the IHS CERAWeek energy conference broadcast on CNBC.com.

“There will be breakthroughs in battery technology, they’re on the horizon,” Akerson said. “We’re actually developing a car today which is really anathema to the way the auto industry works: We’re running a dual play on the technology to see which one will succeed. One will result in” a 100-mile range, “the other will be a 200-mile range.”

Akerson went on to say that fuel consumption can be reduced by 6.5 percent if the vehicle weight is cut by 10 percent. GM's goal is to cut weight by as much as 15 percent.

Further, Akerson described GM's previous plans to put 500,000 green vehicles on the roads by 2017. It's doing this with its Chevrolet Volt, the new all-electric version of the Chevrolet Spark and a diesel version of the Chevrolet Cruze.

GM hopes to increase Volt sales by 20 percent this year alone.

“Everywhere you look there are opportunities to seize the energy high ground,” Akerson said. “Indeed, our leaders have been presented with an historic opportunity to create a national energy policy from a position of strength and abundance. The pillars of such a plan must include energy diversity, so we do not become dependent on any one fuel or energy source.”

Last week, Akerson called for a consumer-driven national energy policy where he'd like President Barack Obama to appoint a Blue Ribbon Commission (which would lead to the development a 30-year policy framework for energy security with progress reviews every five years).

15% weight savings is like reducing a 4000 lbs weight car down to 3400 lbs. 600 lbs. That's a dubious prospect when safety features and NHTSA mandated requirements have increased virtually every year.

Then you factor in the additional weight of battery packs (even on an electric only vehicle, the total weight of powerplant & batteries will weigh more than a conventional IC engine & fuel).

Believe me, I'd love to see a return to form for automotive offerings, but those days are gone. The AWD "pig" of a 3000GT VR4 weighed LESS than a current RWD Dodge Challenger V6. Sub-3000 lbs cars are almost unheard of outside of A-Segment european cars & 100% carbon-fiber supercars.

I just don't see this happening.

It is actually quite easy with most toady cars if price is no object. It is only difficult to do if you want to keep the same price.

Dont forget the weight of the govt. mandated back up camera and stability control systems, GM.

Don't forget a black box that is coming if safety nannies have their way.

Already present (in small scale) due to the mandated airbag system.

"Basically what we're gonna do is take a hefty chunk of our own crap, load it down with a bunch of government mandated crap, then marvel that it even runs at all! Oh, by the way, it'll be 15% lighter than the one made without subsidies."

And this is why you can pry my Impreza out of my cold dead hands. AWD and sub 3000 lbs. Awww ya baby :)

Especially not from GM lol. I mean come on, that's like the Afghanistan "space program" saying they can land a man on the Moon in a few years (and bring him back)...
