GM Working on a 200 Mile Range EV?

[rolosrevenge]

This is and interesting article, I want to know more. Tesla may get their first serious competition.

Wishfull thinking. They are still working on battery technology....

Not sure what you mean. As an owner of a 2012 Volt, there is nothing wrong with the battery. The 10 kWh battery that can get 48 miles on just 10 kWh at an ambient temp of 65 degrees.

Hmmmmm, 85kWh/10kWh * 48 miles would indicate GM could get 408 miles out of a battery Tesla's size. Either GM is staffed with genius types or someone is driving their Volt very slow and doing no stop and go (or other normal type driving).

Montgom, why so surprised by Qwk's response? His opinion of GM is only slightly worse than that he holds of the Antichrist...

60 mph on a windless day on a flat freeway in Southeastern Wisconsin. Drive like an old man. 5 mph per kWh is the best I have ever done.

GM is staffed with great engineers.

I actually own a Volt. Soon to own a P85.

The article quotes that GM "is working on Battery technology to see which one will succeed". Either 100 or 200 mile range batteries.

If GM cannot figure out that 100 and 200 mile battery cars already exist and have for quite some time, time for another Bankruptcy.

Some people support incompetence, some don't. We all know which categories you and I fall in...

That's like saying Tesla already built a 400 mile battery because it's possible to travel 423.5 miles in a Model S (as demonstrated in a record drive last year).

I would assume GM is claiming EPA numbers. They say they are working on a 100 mile and 200 mile battery pack. They mention the Spark EV slated for next year gets 75 miles.

By the time GM's pack is ready for production, Tesla will likely have passed 300 miles EPA range in a production car and well on the way to 400+.

I am not 100% sure what QWK was saying. Was QWK being facetious? Sarcastic? Or do I just not understand. I just really enjoy EV and the future they hold.

GM quotes 35 miles on 10 kWh. That is very easy to do (but not in subzero weather). 48 miles is what I can do in ideal conditions. Most Volt owners will tell you a similar story. I hope that my experience with Volt EV driving can translate into 4 miles per kWh with the much heavier and incredibly more potent MS P85 in the same situation. So, 4 miles / kWh x 85 kWh should be a romping stomping result! I am very excited about owning and driving a pure EV like the P85 that can do 0-60 in 4.4 seconds (some say 4.1). Driving around town, at lower speeds, coasting and using one pedal driving I should be able to do it with ease. And then, while being quiet and smooth, blow the doors off of any car around. Pinch me, I am in a dream!!!! I can eat any Porsche, BMW, or big Detroit iron for lunch. And with no emissions and no noise. Just pure, quiet EV power. Sweeeeet!

My guess is that GM could do it tomorrow. They have the engineers to do it. They have the experience. Will they? I don't know. With my P85 coming in the next month, I don't really care. GM can let TESLA do what TESLA does best. I can drive my Volt cross country and I can drive my P85 to work for an entire week with just charging on weekends. Does it get any better than this? I have waited 30+ years for this and I am going to enjoy every minute of it. I don't care if GM or TESLA or NISSAN makes my dreams come true. I never thought I would live to see this day arrive.

For me, it is not about who is better, or first, or right or wrong in their EV approach. It is for me about choice. I finally have choices. No more ICE running. I can charge at night, when the grid is underutilized. What a concept. Lessen my need for fossil fuels. Educate those around me about the possibility of a better future.

I think you are underestimating the time it takes for a battery to reach from the lab to a production car. The Volt was unveiled as a concept in Jan 2007, approved for production shortly after, so GM started looking for a battery supplier (started with 25). By June 2007, whittled it down to 2 suppliers. After a whole lot of battery testing (simulating 150k+ miles and 10 years of wear) they picked LG Chem in Jan 2009. There was more testing in mules and the first official production vehicle rolled out in November 30, 2010.

So almost 4 years of work and they were using existing battery cells from other suppliers. If they were to develop a custom chemistry it'll take even longer.
