New York Times Report on the Chevy Volt Generator Mode Driving Experience
On the same day the Today Show ran its piece on test driving the Chevy Volt integration prototype, Lindsay Brooke, a reporter from the New York Times published his.
Brooks was the only other journalist so far besides CNBC’s Phil Lebeau to test drive the Volt in generator or charge-sustaining mode and has written about it.
His [...]
Chief Powertrain Engineer Pleased With Chevy Volt’s Charge-Sustaining Mode
I had the following discussion with Alex Cattelan who is the Chevy Volt’s chief powertrain engineer. She has a very deep understanding of how the car operates and recently drove in a fleet of integration Volt prototypes through rugged mountains of Knoxville Tennessee.
Do you feel the charge-sustaining (CS mode) experience is now pretty solid [...]
Engineering Design of the Chevy Volt’s Two Electric Motors
I had the following discussion with Alex Cattelan who is the Volt’s Chief Powertrain Engineer. It explains for the first time anywhere in more depth how the Volt’s two separate electric motors function.
The design of the electric motor, is there a separate generator or does the motor itself just turn the other way and act [...]
Bob Lutz Implies Chevy Volt Will Get Between 40 and 50 MPG in Charge-Sustaining Mode
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 Engine Generator Operates Between 1200 and 4000 RPM
The Chevy Volt’s 1.4 L 4 cylinder flex fuel generator garners a lot of attention and discussion online.
It is this range-extender that make the car so unique. Although the Volt always operates as an EV, once the battery’s state of charge reaches roughly 30% this generator powers on, providing electricity to the motor. [...]
Volt Runs Without Gas Though Needs it Occasionally, Can’t Run Without Battery
Since the Volt is at its core and electric car, people often ask whether it will be able to run without any gas in its tank.
According to Volt vehicle line engineer Tony Posawatz, “the VOLT can run without gas since it is an EV.”
Here’s how he explains it:
We will provide many tips to customers on [...]
Poll: What Will the Volt’s MPG in Charge Sustaining Mode be?
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 [...]
Exclusive: The Engineering Challenges of Volt Generator Mode
After the Chevy Volt has been driven 40 miles on electricity, the gas-powered generator turns on supplying electricity along with a buffer in the battery that the electric motor needs for continued operation. Though GM has been developing this function for a while they have not shown it publicly.
I had a chance to discuss this [...]
EPA Playing a Role in Volt Generator Mode Behavior?
It is known that no one outside GM at this point has been allowed to witness the Chevy Volt prototypes running in generator mode.
Previously it was reported that the reason for this is that the car isn’t soundproofed and GM doesn’t want people to hear the engine. Jon Lauckner has also told me the [...]
Chevy Volt Mule in Generator Mode Already ‘Prius Quiet’
General Motors has allowed the Cruze-bodied Chevy Volt mules to be test driven by more than a dozen journalists and various others including myself.
They have strictly restricted those driving experiences to the vehicle’s charge depleting mode. Outsiders thus only have the experience of driving the car in pure electric mode without the gas generator [...]
What Will the Volt’s Generator Mode Feel Like?
GM has not let any of the media including myself experience driving in the charge-sustaining or generator mode in the Chevy Volt mules. There might be some concerns about how it will be experienced possibly leading to some negative press.
While I was at the Milford Proving Grounds I was told that many people who drive [...]
Gen II Volt Engine Less Than 1 L, Smaller and Simpler
Now that electrification has begun to take hold, the roles will be reversed from present day hybrids. Instead of a small electric motor assisting the main gas engine, the gas engine will take a backseat. This is well illustrated in the Volt where the gas engine simply waits until its services are needed only if [...]
