Tesla Cybertruck Engineer Reveals New Changes in ‘Constantly Evolving’ Pickup
Lead engineer Wes Morrill details a switch from aluminum to self-reinforcing polypropylene for the vehicle's aero shield.
Tesla Cybertruck Lead Engineer Wes Morrill has disclosed a series of manufacturing updates to the all-electric pickup, describing the vehicle as a “living thing, constantly evolving and improving.”
What Happened
According to Morrill, Tesla has implemented incremental changes to the Cybertruck since its production launch at Gigafactory Texas. These adjustments focus on improving cost, reliability, serviceability, and manufacturability. While some modifications remain undisclosed, Morrill highlighted a specific change to the aero shield located beneath the truck. Tesla has replaced the previous aluminum shield with a self-reinforcing polypropylene material. Morrill explained that this material is “stretched into fibers and then laminated into the form,” resulting in a component that is lighter, more durable, and significantly cheaper to produce than its aluminum predecessor. The switch also allowed for geometric improvements around bolts and edges, contributing to better durability and reduced drag.
Why It Matters
The update illustrates Tesla’s approach to product development, which diverges from traditional automotive cycles. Unlike legacy manufacturers that introduce sweeping changes at model year boundaries, Tesla implements fluid updates based on engineering needs. This strategy means Cybertruck ownership may involve variations in parts and specifications that are not always clearly delineated by model year. Instead, owners often identify their vehicles by “generation” or “era,” a practice seen with the Model Y “Juniper” and Model 3 “Highland” refreshes. For buyers and owners, this continuous improvement cycle suggests that newer production units may offer tangible performance and durability benefits over earlier versions, even within the same model year.
The Bottom Line
Tesla continues to refine the Cybertruck through ongoing manufacturing adjustments, most recently swapping the underbody aero shield to a polypropylene composite for improved efficiency and cost savings.
