Chevy Volt Charging Strategy Redux

Ben Wojdyla — Fri, 26 Sep 2008 16:00:00 EDT

Edmunds Inside Line stirred up kind of a hornets nest yesterday when they reported the Chevy Volt won't use the engine to recharge the battery, spurring a similar story from us. Both of us were told by GM PR we were correct in making that assertion. Turns out the PR team was having the same problems both us and Inside Line were having in understanding how the Volt's engine/battery/motor system will work. GM's VP for Global Program Management, John Lauckner, rebuffing the initial claims, stated, in no uncertain terms, the engine can recharge the battery, but recharging the battery is not its objective. Whatever that means. All we know is engines are most efficient when operated at a steady state — tons of tricks can be implemented to optimize performance at a constant RPM, and that's the plan for the Volt.

As with any steady-state output, sometimes there will be surpluses. Those surpluses of electricity not used by the electric motor, as might occur during light loads, will be dumped into the battery so that energy isn't wasted. But recharging the battery is not the objective of running the engine. In addition to extra electricity from the engine/generator, energy reclaimed from regenerative braking will also be stored in the battery. Over an extended period of these surpluses being added to the battery, it's possible for the engine to switch off and the car to return to all-EV mode for an unspecified distance.

So, let's be clear here — contrary to the second set claims of GM PR on the Volt's engine — it can in fact recharge the batteries. You could almost say GM was for this claim before it was against it — and is now for it again. Stinkin' buncha flip-floppers.[Edmunds Inside Line]

Chevy Volt: Taste The Rainbow

Andrew Stoy — Mon, 15 Sep 2008 12:20:00 EDT

An aspiring designer at GMInsideNews has taken it upon himself to restyle the Chevy Volt, responding to criticism that the plug-in corporate savior is a bit on the bland side. Aside from applying a selection of questionable hues to the Volt, he sketched in "lightning bolt zigzag style headlights" in an effort to give the design some teeth. The beltline has also been jacked into a pseudo-G6 high-rise tribute, resulting in an effort that's arguably more derivative than the prevealed Volt we've already seen. What do you think? Full renderings in technicolor goodness after the jump.

Edmunds Thinks Chevy Volt Design Is "Huge Disappointment," "Completely Unacceptable"

Ben Wojdyla — Mon, 15 Sep 2008 11:20:00 EDT

The Line on the Inside at Edmunds has cobbled together a series of quotes allowing them to say what they think without actually saying what they think: The 2010 Chevy Volt is ugly. Quoting Jane Nakagawa of their own Edmunds AutoObserver, they bust on the Volt pretty hard, calling it "a huge disappointment" and "completely unacceptable." Harsh. If the "leaked images of the Volt" with their recklessly unflattering photo angles are to be believed, the Volt may be ugly, but we'll reserve judgment until we see it in the flesh tomorrow morning during the live unveil at the Renaissance Center.

Chevy Volt To Get Occasional Power From Cruze's 1.4-Liter Inline Four-Cylinder

Ben Wojdyla — Wed, 30 Jul 2008 10:00:00 EDT

We all know the story on the 2011 Chevy Volt by now — inline hybrid, electric motors, giant T-shaped lithium ion battery, 40 mile all-EV range, late 2010 debut date and "on-board range extender." Well, we didn't know so much about that last one until now. GM is confirming the same 1.4-liter in-line four-cylinder set for duty in the Chevy Cruze will be doing the electricity-generating duties for the Volt.

Combined with the planned GM 100th anniversary production skin reveal coming up ahead of the 2008 Woodward Dream Cruise, we're just about to the point of knowing all there is to know about the Volt.

Jalopnik Snap Judgement: This is the right way for GM to go with this program. The original Volt concept had a 1.0-liter turbocharged three-cylinder — little more than a snowmobile mill. The 1.4-liter will offer the reliability of a regular production engine but just as importantly, reduce the number of engine lines GM has to run. In fact, thanks to the news from those leaked UAW documents that the Volt would be built in GM's Hamtramck plant and the Cruze will be built in the Lordstown, OH plant — they'll only need one engine build location near the two — like the expected Flint engine plant.

With your average engine costing about a billion bucks to develop and put to production, and the weight and packaging between the two engines being about the same, this one is practically a no-brainer. Now, if only they'd turbocharge it for a Volt SS! Yeah, 'cause that'd be cool. Actually, no it wouldn't be.
