I had the chance to ride in the Chevrolet Volt prototype that GM staff drove from Austin Texas to New York City on July 4th.
This particular prototype, called “a golden IVer” due to its proximity to a final production car, had been built in December 2009, and had nearly 10,000 engineering miles on it. The software controls were more than 99% complete according to Will Handzel, the GM controls engineer who actually drove the car. Interior surfacing was still a bit rudimentary and there was a bit of wear and tear inside.
This was my first chance to ride in the Volt (I had the passenger seat) in real-world highway driving situations, though I have driven it for about an hour, sub-50 mph around around a test track. We took the car about 15 miles from Liberty Park in NJ to midtown Manhattan.
I found the car very cheerful, pleasant and bright. It was spacious and airy inside. Even though the day was bright and sunny, the LCD displays were very bright, crisp and vivid. I saw the OnStar navigation system in action and it worked perfectly, as did the handsfree phone and the capacitive controls, though Will felt they took a bit of getting used to.
When we started off in the car it had about 4 miles of EV range, and once again I missed the switchover to generator mode, never noticing it. The car was smooth and solid all the way. The only sound I could notice was from the fan from the air conditioning which worked terrifically, in comfort mode, on a day it was more than 95 degrees outside.
I specifically asked Will to demonstrate accelerating from 55 to 80 MPH, while we were on the highway. When I asked him, he said throughout his 1776 mile drive, and indeed all his Volt driving, passing on the highway was never a problem. ”We never had an issue,” he said. Acceleration from low speed and stop certainly wasn’t a problem, the car springs onto the highway with gusto.
Acceleration from 55 to 80 was strong and linear. There was no customary downshift effect people may be accustomed to in traditional vehicles, but, that really didn’t matter. The car swiftly made it to high passing speed in a constant and confident fashion.
Yes, this is different than a standard gas car, but in my opinion represented no trade off or loss of function. It worked wonderfully well.
It was also very quiet while driving. After getting out and standing aside it, while it was idling in the heat, the engine could be heard running.
Still no final word on final fuel efficiency numbers, as GM still says they are being negotiated with the EPA, but obviously will be finalized and made public soon. Expectations are that fuel economy will be somewhat above that of the best-in-class standard gas compact car.
In conclusion, there are no surprises here, the car handles capably in the highway setting.
