LeBron's Electric Hummer, Porsche EV Will Converge at Super Bowl

Here’s a sure sign that someone besides Tesla Inc. wants to actually sell electric vehicles. Big, old-school carmakers are driving the EVs out from the shadows of backstage and into the spotlight by spending millions to advertise them in the Super Bowl.

This Sunday, General Motors Co., Volkswagen AG’s Audi and Porsche will show off their new electric models. The Super Bowl ads, which according to Adweek cost $5.6 million for 30 seconds, are looking to generate buzz just as automakers start to roll out 121 new EVs over the next five years, up from 18 now, according to researcher LMC Automotive.
