Roaring into No. 1 for her third straight year, Barra remains in the driver’s seat even as crosstown rival Ford ousted CEO Mark Fields in May. Proving that GM won’t be counted out in this era of disruption, she beat Tesla’s much-hyped Model 3 to market with the Chevrolet Bolt EV, which launched in 2016 with a battery that can outlast Tesla’s; it’s now the top-selling non-luxury pure electric car. Barra also has her eyes on a driverless future: After acquiring self-driving tech startup Cruise Automation last year, GM has begun testing autonomous Bolts, and its new car-sharing service Maven is offering deals to Uber and Lyft drivers. The stock is starting to respond, climbing 25% over the past 12 months, and revenue ticked up 9% in 2016—GM’s biggest sales growth in years.
