Tesla's Autopilot Hit With More Turmoil as Leader Departs for Intel

Mr. Keller joined Tesla in 2016 from chip maker Advanced Micro Devices Inc. to serve as vice president of Autopilot hardware. He assumed control of Autopilot software as well last June, following the departure of Chris Lattner, who left only six months after Tesla hired him away from Apple Inc. "Prior to joining Tesla, Jim's core passion was microprocessor engineering and he's now joining a company where he'll be able to once again focus on this exclusively," Tesla said. Electrek, a blog that closely follows Tesla, earlier reported Mr. Keller's departure. Tesla has had several departures from its senior ranks since the start of last year, including its top sales executive and chief financial officer. The company is struggling to ramp up production of the Model 3, a sedan that is supposed to help make the electric-car producer more mainstream.
