TESLA’s truck looks like something that a second grader would design. AFP

CALIFORNIA (AFP) — Tesla slumped 6.1 percent after its launch of an all-electric pickup truck drew several lackluster reviews, with analysts saying the space-age design was unlikely to challenge top-selling models by Ford and other conventional car companies.

The launch also included an embarrassing moment for Chief Executive Elon Musk, who was heard using an expletive when the vehicle’s supposedly indestructible windows cracked after being struck with a steel ball.

Some “important unanswered questions” hang over the vehicle, said Deutsche Bank, including whether the design was “too polarizing” and whether it would be able to carry heavy loads without requiring customers to opt for higher-cost trims.

“Will commercial buyers trust Tesla’s build quality?” Deutsche queried. “While the materials used appear robust, there could be questions about the truck’s durability when used under work conditions, especially in light of its seemingly unibody construction.

“And the shattering of the truck’s unbreakable glass windows during the live demonstration was not a good start.”
