Humans come in many different sizes and we placed the rear window switch in a location to try to balance reach of both the window switch and door handle. A review of fleet data showed unintended window opening (brief open/close) typically due to someone leaning forward, elbow hitting the switch. Realizing we didn't get it perfect the first time, the team improved this by moving the window switch forward by about 50mm and that seems to have done the trick

In-house 4680 cells got better, several times actually. And the firmware controls improved as well - both enabled faster Supercharging. Hitting 500kW peak and more importantly shrinking the 10% to 80% charge times by several minutes. Not to mention every efficiency improvement I've mentioned also effectively increased charging speed when measured as what matters on a road trip: miles recovered per minute

Motor noise is cool to hear, but when driving down the highway most people want silence The Motor and NVH team kept on it and made a major reduction in structure-borne noise through a bushing diameter and dynamic stiffness change that reduced motor prominence by up to 12 dB

The side repeater camera was updated - the version on the left is the newer part which uses passive geometry to create airflow disturbance that better keep water off the lens while driving. No cost penalty, just pure vision improvement.

How about improved efficiency that even existing owners can benefit from? An underappreciated part of any vehicle - the only reason you can start, stop, and turn - Tires There is a lot that goes into the design and construction of a tire and optimizing efficiency vs capability. Tesla's fantastic tire team was able to find a way to get even better rolling resistance from the 20" All-season. Which means when you buy your next set, your truck will become even more efficient. Put simply, tires continuously deform as they roll down the road. That flex causes internal friction in the rubber and turns mechanical energy to heat, wasting power that could have gone into moving the vehicle. Reduce the waste heat, and you have more energy for useful work. The 'T1' designation is the latest and greatest so keep an eye out when you need to replace your tires.

Firmware has been constantly evolving as well - even today, we are shipping a new feature for Cybertruck to collaborate with powerwall 3 to extend the energy available to your home when the grid is not. A first of its kind, ambitious feature to seemlessly integrate two different energy sources into one cohesive grid through the same wall connector used for charging. This presented a few different microgrid stability challenges and in particular ensuring robust communication and coordination to react to load changes in real time took some effort, but the energy team and vehicle team worked hand in hand to get it to out to the customer fleet

I was surprised by how interested people were to find out we made a relatively benign change to the Cybertruck aero shield, a part of the car most people never even see. So I'll share some more details. Here are two photos, the left is one of the latest trucks off the production line and the right is one of the first 1. The obvious change from Aluminum to a new black material - many assumed it's Carbon fiber due to the color and pattern. It's actually a self-reinforcing polypropylene. The PP is stretched into fibers and then laminated into the form. It turned out to be more durable, lighter and cheaper than the aluminum when manufactured this way 2. The material change also enabled geometry improvements around the bolts and edges as well as minor form changes. These couldn't be easily done in stamped Aluminum but all benefited aerodynamic drag The end result was a part that is better for aerodynamics, and better for impact resistance while reducing cost and mass. This is a part no customer sees or really even thinks about, but we made it better anyway

I've been looking forward to this bed box accessory, it nicely integrates with the storage bins and spare tire. Plywood and other long items can fit underneath - Plus relatively quick to remove if you need the entire space back for something large. And more L-track to boot
