Dave G: The Volt gets 40 miles all-electric range both city and highway.

This nonsense is getting old.

I point out the shorter range as a result of WINTER and you totally disregard it.

The few observations we have available state that the change in driving conditions combined with use of the heater sets the expectation to about 75 percent the usual capacity. That would make it about about 30 miles rather than 40 …a big difference without any mention whatsoever on the spreadsheet.

Re London congestion charge:
Just Google London congestion charge +EV and there is a lot of info. I tried, but can’t get to post. Low carbon cars get exempt – Prius Yaris, etc Don’t know re Volt.
HTH and gets through,

Thanks! It’s very interesting. They certainly are more active about promoting EVs than we are in New York.

As for yours, why the heck are you even comparing a plug to a non-plug?

john1701a: Really? I pointed out the need for an update to avoid misleading due to only using the CITY estimate. But rather than saying thanks and doing a revision, I get accused of bashing.

The Volt gets 40 miles all-electric range both city and highway.

The vast majority of the 230 MPG EPA figure comes from the 40 miles AER. Also, GM says 230 MPG EPA city is something they can easily attain, and they expect to beat that. In addition, like most hybrids, the MPG in range extender mode is usually close to the MPG city, usually only 5% less.

Any calculations at this point have to be plus or minus 10-20%, since we don’t have final exact figures, and the difference between city and highway EPA MPG for the Volt will easily fall within that range of error.

So I believe you’re being misleading my nitpicking my numbers.

And again, where are your numbers? If you thing my numbers are wrong, then you provide and estimate of how much the Volt will save over the Prius in fuel costs…
