I must admit I am still amazed that we are actually beginning to talk about a near finished product, the Chevy Volt integration vehicles (IV). Over 2 and a half years ago when I first started this site, (SEE FIRST POST HERE) this point was a time that was unimaginable and yet now has come to pass.
We now have running Volts true-to-form with pictures, videos, and new information. We just had a live chat here with the Volt’s Chief Engineer, Andrew Farah, the only known person to drive one of the new cars. Many of us asked questions, including myself, which went unanswered. Farah chose the ones he wanted to answer from a list, and only had an hour. So what if anything new did we learn? Lets see:
Appearance
He allayed concerns people had about the appearance of the IVer, noting items such as the “head lamps, tail lamps, and paint on the spoiler” were not true to production form at this point because they didn’t need to be for testing. These features will look differnt in the production product.
Handling
He specifically said the Volts’ chassis is “much more sporty” than either the Prius or Insight. Great, but that really isn’t saying much.
Battery Leasing
It is my understanding GM has not yet decide whether to lease or sell the battery. Farah said his team is “working form the perspective that it will be sold with the car,”‘ and will have a 10-year life.
Software/GUI
Farah says the graphic user interface (GUI) on the 2 LCD dash is complete from a software architecture control standpoint, but its appearance will still be refined and calibrated over the next few months.
Gas Tank Size
Farah still says the car will deliver “more than 300 miles” on a full tank of gas and full charge, but claims “we’re still balancing the size of the tank with other factors.” On a side note, I have recently been told by GMs Director of Hybrids and EVs Bob Kruse that the gas tank size is now considered a known entity. …still a veil of mystery here.
Future of EVs from GM
Farah says, “electrified vehicles will certainly be a significant portion of our future sales.” Though recently CEO Fritz Henderson told me gas cars will still make up “the lion’s share” of GMs portfolio in 10 years.
Charging Port Connector
He says his team has adopted a “revised SAE J1772 charge port/connector specification” that is larger than what has been shown previously, but will work with public chargers that are greater than 120V. He said the port was moved down to its own door location because “the SAE connector is a bit larger than would fit under the fender trim,”…”we moved it down to accomodate [sic].”
Charge Sustaining Mode
My question, which was ignored, is what genraotr mode sounded and felt like. To another questioner, Farah said he was “extremely pleased” with driving in the current calibration of charge sustain (generator) mode.
Trim Levels
Farah confirms there will be more than one trim level, “as with most other Chevrolets.”
Engine Noise at Stop
Farah confirms “our plan is to stop the engine when the vehicle comes to rest.”
Engine RPM
Our own N Riley asked if GM “will reduce engine rpm as the speed of the car decreases to keep it sounding like it is trying to run away?” Farah said Riley’s suggestion “clearly makes sense” and although not specifically promises this will be the case, reassures us that his goal for the Volt is it “should not surprise (drivers) unnecessarily.”
Cold and Hot Operation
Farah confirms hot weather testing out West will soon be underway but that the IVers have been operating at 90 degree temperatures in Michigan. He confirmed what we’ve heard in the past that at extremely low temperatures, the car will “use the engine to supplement the battery.”
