Bob Lutz Implies Chevy Volt Will Get Between 40 and 50 MPG in Charge-Sustaining Mode

October 27th, 2009 | Posted in: Efficiency, Generator with 196 Comments

GM vice-chairman Bob Lutz was interviewed on Fox Business News.  The entire interview can be watched at the bottom of the post.
Just as vehicle line director Tony Posawatz was asked by Fox the other day, Lutz was also asked what the Chevy Volt’s MPG will be when it is running in charge-sustaining mode, after the [...]

Chevy Volt Will Get More Than 32 MPG in Charge-Sustaining Mode

October 25th, 2009 | Posted in: Efficiency, Video with 121 Comments

A question that remains unanswered by GM is what the Volt’s MPG will be in charge sustaining mode or while the generator is running.
When the Volt concept was first unveiled math models put it at 50 MPG, however since development began in earnest GM has kept silent about what it is actually turning out to [...]

Poll: Volt Will Offer a Low Power HVAC Option, Will You Choose it?

October 15th, 2009 | Posted in: Efficiency, Features with 140 Comments

One question the Volt engineering team is often asked by journalists is how much accessory electric draw will effect the Volt’s 40 mile all electric range.
Clearly there will be an effect.  During the recent 30 to 40 degree mornings I, for example, have been driving my MINI E electric car with the heat on moderately [...]

Chevy Volt Display May Not Show Instantaneous MPG

October 6th, 2009 | Posted in: Efficiency, Features, Interior with 238 Comments

The Chevy Volt has two configurable LCD screens, one behind the wheel where traditional gauges are typically found, and one atop the center stack. The latter will also be a touch screen. I have seen it in person in a pre-production car and was very impressed with its crispness, vividness and high definition.
We [...]

GM Exec: Volt to Have Very Cool Eco-Graphic Interface

October 5th, 2009 | Posted in: Efficiency, Features, Interior with 146 Comments

The following is a discussion I recently had about the Chevy Volt with Bob Kruse who was GM’s director of hybrids and EVs, just before his recent departure.
I would imagine driving style will affect the Volts’ electric range. Hyper-milers probably will try to get the car to go 100 miles without going into generator [...]

Fisker Karma EREV Expected to Get 67 MPG Combined Fuel Efficiency

September 9th, 2009 | Posted in: Competitors, E-REV, Efficiency with 237 Comments

The Fisker Karma is the “other” extended range electric car deliveries of which are expected to begin in 2010. Only in Fisker’s case its May as opposed to November, and will be simultaneously global.
Although the Karma shares the same general engineering architecture as the Volt, the similarities end there. The car will have a 50 [...]

Should MPGs be Retired? – How to Calculate Efficiency of New Technology Cars

August 28th, 2009 | Posted in: Efficiency with 326 Comments

For the last 100 years, calculating a car’s efficiency was easy, one determined how many miles a car could travel under certain standardized conditions on one gallon of gasoline.
However, the new era of electric and partially electric cars is turning that convention on its head.
This was too brought to a head earlier this month when [...]

Poll: What Will the Volt’s MPG in Charge Sustaining Mode be?

August 18th, 2009 | Posted in: Efficiency, Generator with 484 Comments

Now that GM has announced the Volt will average 230 MPG in city driving, we are interested in knowing more.
When the Volt concept was first unveiled in January 2007, GM said the car would get 50 MPG average when it was in generator mode based on computer simulations.
We understand the car will get up to [...]

GM Still Claims Volt Will Get 40 All Electric Miles Both Highway and City, But Under What Conditions?

August 13th, 2009 | Posted in: Efficiency with 200 Comments

When GM announced the Chevy Volt should be rated at 230 MPG in city driving, they also divulged another efficiency rating.
Pure electric cars are generally rated in terms of kwh per 100 miles to show how efficient the vehilce is at using electrical energy. Since the Volt will drive the first 40 miles without [...]

How the Volt’s 230 MPG Designation was Calculated

August 12th, 2009 | Posted in: Efficiency, Original GM-Volt Interviews with 446 Comments

Yesterday was the highest traffic day in the history of GM-Volt.com, with over 60,000 visitors, and I apologize for the slowness of the site.
Why was this? Of course because GM announced that the Volt would get an EPA rating of more than 230 MPG. As exciting and compelling as that number is, it [...]

We recently learned GM will be moving its 2-mode plug-in hybrid drivetrain into a yet-unseen, yet-unnamed Buick compact crossover.
It has been noted that though the standard version of this car will come with a DI 4 cylinder engine capable of more than 30 MPG highway, the plugin version will not.
It will have a direct [...]
