Tesla Inc.'s launch of its futuristic Cybertruck pickup suffered a setback when its armored glass windows shattered, but it was the overall look of the electric vehicle that worried Wall Street, driving the automaker's shares down 6 percent on Friday.
In the much-anticipated unveiling to cheering fans late on Thursday, Tesla boss Elon Musk had taken aim at the design, power and durability of mainstream trucks, only to be shaken when his boast about his new vehicle's windows backfired.
After his head of design, Franz von Holzhausen, cracked the driver's side window with a metal ball in a series of tests for the crowd at the event in Los Angeles, Musk said, "Oh my fâ-ing God, well, maybe that was a little too hard."
