That’s still a mystery, but GM told SAE International the completely revised Voltec powertrain will grant 12-percent improved range and energy usage.
All things being equal, that would boost the existing 2015 model’s 380 gas-plus-electric miles to 425 miles but for Volt owners this is far less vital than all-electric range.
“Superior range (particularly in EV mode), fuel efficiency, and power were the top three requests from owners of 2011-2013 Volt models,” said a report by SAE International citing Larry Nitz, GM’s Executive Director, Transmission and Electrification.
Of course everyone already suspects as much, and guesstimates have been from the high 40s to 50-60 range, but the otherwise vague disclosure of 12 percent is another solid clue, at least.
A Nissan Leaf gets up to 84 rated miles, but being an EV, it cannot run to unfilled, so if it’s safe at 70ish, a revised Volt with perhaps 65-70 percent the range – plus gas backup
As for fuel mileage, the 2015 Volt was rated at 37 mpg combined in gas operation. The 2016 will run on regular, not premium, and a 12-percent increase would boost the ancient car’s 37 to 41.4 mpg, which might mean 41-42 on the sticker, but this too was not told.
A Toyota Prius Liftback is rated at 50 mpg and next year will be improved with generation four.
GM is withholding specific efficiency numbers until the Detroit reveal, but does say it responded to its driver pool who gave extensive feedback for GM to re-engineer the powertrain.
There is one misreport floating
The specific room of the pack was not told by SAE International’s report, but as reported earlier it’s 30-percent lighter, and has a reduced number of cells from 288 to 192 (still 96 cells in parallel).
Really the whole Voltec powertrain is a fresh start, and also now 130 pounds lighter with the 1.5-liter’s aluminum block accounting for a excellent chunk next to the iron block of the outgoing 1.4 liter.
“I can’t reckon of a powertrain we’ve re-engineered more extensively within a five-year period than this
A revised TPIM (traction power inverter module) is now direct mounted to the transmission case eliminating the heavy orange 400-A cables. GM said the focus was system integration.

The 1.5 liter reduces NVH (noise, vibration and harshness) and the 1.0-liter turbo everyone plotting was going to be installed was unacceptably noisy at points, especially at start up.
In all, efficiencies were found in re-vamping much of the system which now uses two redesigned motors. The new Volt has 20-percent low-end power, is lighter, quieter, has more range.
