 Auto workers worry that producing electric cars will require fewer workers. Maybe not, some

 researchers say

(CNN) - The traditional automobile engine is a marvel of complex engineering, with pistons that move up and down, springs that compress and expand, shafts that rotate, valves that 

open and close, and gears that rotate and interlock. Not to mention that the transmission that connects the engine to

 the wheels is a complex machine in itself. An electric motor, on the other hand, simply consists of magnets wrapped in wires and

 only requires a single-speed gearbox. This simplicity worries the
United Auto Workers union.

An oft-repeated estimate is that electric vehicles require 30 to 40 percent less labor than gasoline-powered cars because they have fewer parts under

 the hood. However, it's not that simple, and some researchers say the labor savings from using electric vehicles have been vastly overestimated.

People assume these estimates are true, said researcher Turner Cotterman, because they are largely based on the number of moving

 parts in an electric vehicle. Because electric cars have fewer parts than gasoline-powered cars, people think they require fewer workers to produce, said Cotterman, who worked on

 a report on the subject at Carnegie Mellon University and is now affiliated with McKinsey and Company.

“It was assumed that there was a linear relationship between the number of parts and the

 labor required to produce them,” Cotterman said.

But making electric vehicle powertrains — batteries, electric motors and energy management systems — requires more, not

 less, work overall than making engines and transmissions, said Erica Fuchs, a labor researcher at Carnegie

 Mellon. He worked with Cotterman on a research paper analyzing the operating requirements of electric and gasoline powertrains.

Researchers at the Boston Consulting Group came to a similar conclusion

. They found that making a complete electric vehicle—without a powertrain—requires only slightly less work overall than making a gasoline car.

"If you look at today's vehicle - an electric vehicle versus an internal combustion engine vehicle - there is a difference of a few percentage points or

 a few percentage points in the man-hours required to produce that vehicle," he told Nathan Niese . global electric vehicle industry leader at Boston Consulting.

These reports are among several research reports that overall have found little difference in man-

hour requirements for the production of electric vehicles compared to gasoline-powered vehicles. Gerald Johnson, GM's executive

 vice president of manufacturing, made a similar statement in a GM video about union negotiations posted on the company's website.

“We did our analysis at General Motors, and there are other studies

 that confirm that

 the workforce needed to produce electric vehicles in the future is very similar to that required today for a comparable [internal combustion engine] vehicle. is needed,” he said. She said. . He said.
