The development of steer-by-wire systems, or drive-by-wire, is quickly making the traditional steering wheel obsolete. These systems remove the direct mechanical connection between the steering wheel and the tires, instead sending signals to steer.
This advancement has been on Tesla's radar for some time, and a well-known Tesla watcher believes they will debut it in their Model S and Model X in 2023.
Chris Zheng, who has insight into Tesla's supply chain now thinks Tesla may be looking to implement steer-by-wire in the Model S and Model X. He tweeted: Looks like Tesla will have Steering by Wire in 2023, at least the Model S/X? Consider their Yoke steering wheel.
Steer-by-wire
The yoke wheel was revealed along with the new Model S in the summer of 2021. While it has a unique look and may up the cool factor of the car, many observers were not fans of the wheel. The shape does not allow for any hand-over-hand steering, and it can lead to completely crossing the driver's arms for tight corners.
However, this design would be perfect for a steer-by-wire system and it may have been Tesla's plan the entire time.
Steer-by-wire system compared to a traditional mechanical system
Elon Musk responded to the criticism of the yoke while addressing the drive-by-wire system. In a tweet dated June 17, 2021, he tweeted: I’ve been driving with the yoke for a while & it’s great imo. Progressive steering would require complex gearing or drive-by-wire without direct mechanical link. Will aim for that in a few years.
A lot has happened since that tweet was posted. The competition in the EV sector has jumped significantly, and Toyota, which is late in the electric vehicle market, got the drive-by-wire first. The system appeared in renders later in 2021 and is now in the 2022 Toyota bZ4x and the 2023 Lexus RZ450e. Surely, this has moved Musk’s “few years” goal up by a year or two.
Advantages of Steer-by-wire
There are many reasons why Telsa would ramp up the production of steer-by-wire. Firstly, the company is continuously looking for ways to reduce parts in the vehicle and therefore speed up the production time. Taking the steering column out, which connects to the universal joint before getting to the rack-and-pinion system, would save some manufacturing time.
Secondly, drive-by-wire delivers a much smoother drive as the steering wheel is no longer connected to something that is on the road. The wheel would not vibrate or pull-on uneven surfaces, making it safer for many drivers, especially those with disabilities or senior citizens, to operate the car.
Finally, the advanced system reacts to several variables to produce a precise steering ratio. That means if you are making a tight turn at slow speeds, perhaps in a parking lot, you would not have to rotate the wheel as much; in fact, it would eliminate hand-over-hand steering altogether.
While the yoke-style wheel wasn't a hit to start, it is perfect for a steer-by-wire system. With competition heating up in the EV market, Tesla is sure to implement this innovative technology sooner rather than later.
For the first time in quite a while, Tesla has increased the price of one of its vehicle offerings. The Model S Long Range and the Model S Plaid have both received a hefty price increase. However, not all is bad - as Tesla also added a new benefit for buyers.
Price Increase
The price increase for the Model S is $5,000 - currently only in the United States. This price increase will likely impact other markets, including Canada, in the coming days.
The Model S Long Range now starts at $79,990, while the Model S Plaid now starts at $94,990. The Model S and Model X now have the same starting price. Interestingly, that’s also the same pricing point for the Cybertruck AWD and Cyberbeast Trimotor non-Foundation Series.
The vehicle configuration does not appear to have changed, so the new pricing is simply an increase rather than the addition or removal of features. Tesla previously cut the price of the Model S and Model X by 15% in 2023, so this could simply be an adjustment to ensure that the vehicle pricing stays in line with inflation and other factors.
Free Lifetime Supercharging
For those on the fence about ordering a Model S, Tesla has brought back Free Lifetime Supercharging when you order a new Model S on or after December 13, 2024. As always, Free Lifetime Supercharging is restricted to the buyer’s Tesla account and to that specific vehicle. It cannot be transferred to another vehicle or another owner after ownership transfer. It’s worth noting, that it also doesn’t exclude the owner from receiving Supercharger idle fees or congestion fees. There is currently no end date for this promotion.
There are currently no changes to the Model X, neither a price increase nor the addition of Lifetime Superchargering. However, when Tesla makes changes to one of their premium vehicles, it usually affects the other one as well. So be on the lookout for potential changes to the Model X offering in the coming days.
We’ve seen Tesla value Lifetime Supercharging at $5,000, so this falls in line with the price increase we’re seeing. It’s possible that Tesla will begin to bring back Lifetime Supercharging as a perk for buying into their more premium Model S and Model X cars, or this could be another temporary promotion to get buyers who are on the fence to go ahead and make their purchase while this promotion lasts.
Tesla recently showed off a demo of Optimus, its humanoid robot, walking around in moderately challenging terrain—not on a flat surface but on dirt and slopes. These things can be difficult for a humanoid robot, especially during the training cycle.
Most interestingly, Milan Kovac, VP of Engineering for Optimus, clarified what it takes to get Optimus to this stage. Let’s break down what he said.
Optimus is Blind
Optimus is getting seriously good at walking now - it can keep its balance over uneven ground - even while walking blind. Tesla is currently using just the sensors, all powered by a neural net running on the embedded computer.
Essentially, Tesla is building Optimus from the ground up, relying on as much additional data as possible while it trains vision. This is similar to how they train FSD on vehicles, using LiDAR rigs to validate the vision system’s accuracy. While Optimus doesn’t have LiDAR, it relies on all those other sensors on board, many of which will likely become simplified as vision takes over as the primary sensor.
Today, Optimus is walking blind, but it’s able to react almost instantly to changes in the terrain underneath it, even if it falls or slips.
What’s Next?
Next up, Tesla AI will be adding vision to Optimus - helping complete the neural net. Remember, Optimus runs on the same overall AI stack as FSD - in fact, Optimus uses an FSD computer and an offshoot of the FSD stack for vision-based tasks.
Milan mentions they’re planning on adding vision to help the robot plan ahead and improve its walking gait. While the zombie shuffle is iconic and a little bit amusing, getting humanoid robots to walk like humans is actually difficult.
There’s plenty more, too - including better responsiveness to velocity and direction commands and learning to fall and stand back up. Falling while protecting yourself to minimize damage is something natural to humans - but not exactly natural to something like a robot. Training it to do so is essential in keeping the robot, the environment around it, and the people it is interacting with safe.
We’re excited to see what’s coming with Optimus next because it is already getting started in some fashion in Tesla’s factories.
