This Lotus-based submarine helped Tesla make the Cybertruck aerodynamic

Jaws dropped, eyeballs froze, and vocal cords fell silent when Tesla unveiled the Cybertruck in November 2019. While its specifications sheet is impressive, its polarizing design caught everyone’s attention and split every opinion. The California-based firm explained a classic British sports car turned into a submarine had an influence on the boxy lines, and it helped make the truck more aerodynamic than conventionally shaped rivals like the Ford F-150.

Company co-founder and CEO Elon Musk is more interested in the future than in the past, but there’s at least one vintage car in his garage. In 2013, he famously spent nearly $1 million on a 1976 Lotus Esprit that had been converted into a fully functional electric submarine (shown above) to star in the 1977 James Bond movie The Spy Who Loved Me. He originally planned to convert the car to Tesla power, but there’s little indication that has happened yet. The wedge-shaped coupe nonetheless became a source of inspiration when Musk and his team began rewriting the definition of a full-size pickup.

Boxy cars normally have the aerodynamic properties of a shoebox, but the angular Cybertruck isn’t a brick; it’s a doorstop. Musk’s beloved Esprit was, too, because it’s a shape that’s surprisingly slippery through air. Still writing on Twitter, Musk revealed his design team might achieve a 0.30 drag coefficient “with extreme effort.” That’s a term used to measure aerodynamism, and the lower the better. To add context, the Model 3 has a 0.23 drag coefficient, the Ram 1500 currently takes the top spot in the full-size truck segment with 0.35, and the Hummer H2 (remember those?) checked in at 0.57.

Musk didn’t detail what it will take to pull off a 0.30 drag coefficient, but he’s absolutely right when he says arriving at that number would be insane for a truck. His team might not have much of a choice: Making the model as aerodynamic as possible will play a significant role in helping Tesla keep its promise of building a pickup capable of driving for over 500 miles on a single charge. Cybertruck production is scheduled to begin in late 2021, so Musk’s team still has a little bit of time to figure it all out before it needs to lock the model’s design and move on to the next phase of the development process.

GMC poured all of its truck-making expertise into the Sierra EV pickup

The Chevrolet Silverado and GMC Sierra pickup trucks are twins, and that will continue to be the case when they go electric.
Chevy unveiled its Silverado EV at CES 2022, and now it’s GMC’s turn. The 2024 GMC Sierra EV borrows some key features from its Chevy sibling, as well GMC’s first electric truck — the Hummer EV. Some of those features were actually pioneered by General Motors two decades ago on non-electric trucks, and are now making a comeback.
You can reserve a Sierra EV now, but deliveries aren’t scheduled to start until early calendar-year 2024. Production starts with a high-end Denali Edition 1 model, with other versions arriving for the 2025 model year.

The Sierra EV updates the design language of the internal-combustion GMC Sierra for the electric age. A big grille is no longer needed for cooling, but it’s still an important styling element that designers didn’t want to break away from, Sharon Gauci, GMC executive director of global design, explained to Digital Trends and other media in an online briefing ahead of the truck’s reveal. The grille shape is now outlined in lights, with an illuminated GMC logo.
Like the Hummer EV and Silverado EV, the Sierra EV uses GM’s Ultium modular battery architecture which, among other things, means the battery pack is an integral part of the structure. So unlike most other trucks — including the rival Ford F-150 Lightning — the Sierra EV doesn’t have a separate frame. The cab and bed are one piece as well, all of which helps increase structural rigidity.
The Sierra EV also borrows the Midgate setup from the Silverado EV. First seen on the Chevy Avalanche and Cadillac Escalade EXT in the early 2000s, it allows the bulkhead and glass behind the cab to be removed, effectively extending the bed. Combined with the fold-out MultiPro tailgate from the internal-combustion Sierra, it can expand the default 5.0-foot, 11-inch bed length to 10 feet, 10 inches. A frunk (GMC calls it the “eTrunk”) provides covered storage space as well.
Because it’s pitched as a premium vehicle, the Sierra EV gets upscale interior materials like open-pore wood trim and stainless steel speaker grilles for its Bose audio system. But the design itself, with a freestanding portrait touchscreen and rectangular instrument cluster, looks suspiciously similar to the Ford Mustang Mach-E cabin. The touchscreen even has the same big volume knob as the Ford. We hope GMC’s lawyers are ready.

Tesla to fix window software on 1M of its U.S. cars

Tesla is sending out an over-the-air update to a million of its vehicles in the U.S. to fix faulty window software that could leave occupants with pinched fingers.

According to a document issued by the National Highway Traffic Safety Administration (NHTSA), Tesla engineers discovered that the affected vehicles may not meet certain automatic window reversal system requirements. It said that in some cases, the window may exert more force before automatically retracting when sensing an obstruction such as a person’s fingers. The condition “may increase the risk of a pinching injury to the occupant,” the NHTSA’s document says.
