Clarification: Gas Engine Can Help the Chevrolet Volt Starting at 30 MPH

regular readers here I have faithfully followed detail of the Chevrolet Volt and every morsel of news the car was no more than a show car and a pen and paper idea.

Over months and years we ve run into controversial moments.

Perhaps has been as controversial as the present gas driving the wheels fiasco.

this week I attended GM s media press conference executive engineer Larry described how the Volt operated.  In the he specifically mentioned 70 MPH as the point where the engine can contribute power to the driveshaft.  He was quite specific can only occur once the is in extended range mode.

I reported this information in detail here in a post Chevrolet Volt Electric System Unveiled .

Soon news started coming out the engine can help drive the car at lower velocities.  I sent a to Mr. Nitz, and spokesperson Rob Peterson

The engine WILL NOT turn on the car is in electric driving mode for your trip two days 50 miles) simply put, it is a battery electric vehicle.

the battery is depleted, the Volt engine engages to create the power to extend the range of the vehicle hundred additional miles.  In range mode the Volt is by either a 1-motor series or combined mode. The vehicle select the most efficient for the driving condition:  1-motor series for almost exclusively below 30 combined almost exclusively 70 mph.

  At speeds in between 30-70 the Volt will select the optimally efficient drive mode the two.

So it turns out the engine can motive force to the Volt at speeds from 30 to 70 mph presumably the power demand calls for it such as and strong acceleration.  Perhaps more than that, t say.

Volt chief Andrew Farah explained a bit more in an interview.

The 70 mile an thing, we re really not sure that came from, he Somebody didn t get the story

He said there were determinants when the engine provide input to the driveshaft.  Its more an issue of torque and than it is of speed, he said.

The has internal programming to determine at points the engine should be in.  It has an efficiency map, and on the efficiency map it will decide to do, said Farah.

The gear-heads us, myself included, want to exactly how the Volt works, and for reason these details are  In the big scheme of things, though, and to consumers, it really doesn t  The car will carry you for 40 without gas.

That s the promise.

After it becomes a hybrid.  It is actually the of current hybrids like the in that in the Volt the electric is the main player, and the gas engine is the  In most of today s hybrids the is true.

 This allows the to have the unmistakable feel of pure drive in all circumstances.  To that I can attest.

Do I feel GM lied to me as whiny journalists have No. Lying is too strong a term.

 It was of a corporate decision to conceal an appropriate time to keep a competitive edge.

I don t betrayed, or frankly really at all.  And to all the journalists lit up about all this I m really not what the fuss is all about..ruffled

What it is about is having the the least oil as possible, without their lifestyles in a car that s looking, high tech, and fun to  And to that mission the holds true in a big way.

GM has an amazing thing here all the odds against them, an for I am extremely pleased that I committed nearly four of my life evangelizing this I should be getting my Volt in 10 days, and I can t wait.

So let us have a of silence and allow this to die a natural death.
