Based on what I've read it's probably about 10-15% less efficient to charge the battery with the gas engine (and then use then use that battery...
I thought you were moving on and looking ahead to the new generation of PHEVs? In any case, the key elements were in line with what I was...
Are you sure about that? I assume by "clean" you mean the EPA combined gas/electric upstream tailpipe emissions calculation on fueleconomy.gov....
I don't think that is obviously true. Stationary utility batteries installed to improve reliability and provide some storage may lower some costs...
We don't yet know that level of detail but you are right that it implies something like a 75-78% SOC range which is quite a bit higher than GM has...
Sorry for any confusion but the plan proposes converting natural gas building furnaces to use electricity-powered heat pumps in order to eliminate...
Actually, I've gotten 48-52 mpg gas-only in my 2011 Volt on long trips driving at 55-57 mph using cruise control but it's a bit tedious without...
There is very little detailed public information about the design of the Malibu's 1.8L hybrid engine. It does not appear to be part of the same...
Yes. It has a wider range of valve timing that it can adjust dynamically under computer control to achieve an "Atkinson" style cycle The only...
Huh? Under this plan there is no natural gas or any other fossil fuel used to power the 2050 CA grid -- it's 100% renewable with almost no carbon...
The reality check based on EPA's fueleconomy.gov, says that a Tesla 70D has full upstream CO2 emissions using US average electricity equivalent to...
The official numbers are in: 53 miles EV range 106 MPGe in EV mode 42 mpg combined hybrid mpg The Results Are In: More Range for the 2016 Volt
Here is a study which discusses how to switch California to 100% renewable energy across the board by 2050. This would provide for a 100%...
You already did. :) This is from the Washington Post energy maps link you posted less than an hour ago: I have no idea if those are accurate...
Supposedly California is now up to 8% solar, according to those Washington Post graphics. Solar is much higher in Germany and we can do much...
We know the EPA ratings for the current 3rd gen Prius vs the current PHEV -- the highway mpg went up by one to 49 mpg from 48 but the overall...
Let's not get carried away now... It's true that beauty is in the eye of the beholder but so is fugly. In my opinion it's an awkward child. Photo...
There is often more than one way to accomplish the same goals. Toyota uses a single mode and compensates for efficiency losses at higher vehicle...
No, not really. The GM highway-speed eCVT ("compound-split") mode is mechanically different from HSD ("input-split"). In input-split MG2 and the...
As I noted earlier, GM's hybrid bus transmission introduced in 2003 implemented a superset of the control algorithms needed for a Prius...
