Tesla has made significant improvements to the new Model 3

MotorTrend

The 2024 Tesla Model 3, also known as the Highland, recently fell into the hands of the folks over at MotorTrend. The staff has been combing through every piece of the car to find the slightest flaw. While the optics of the new look exterior and refined interior get the attention, MotorTrend went poking around underneath the shiny exterior to give a close-up look at significant chassis and suspension upgrades.

Softer Springs and Intelligent Suspension

The 2024 Model 3 Highland, in both its Standard and Long Range variants, has adopted softer springs coupled with innovative frequency-response suspension dampers. This upgrade facilitates a smoother ride, absorbing more significant impacts such as dips, potholes, and bumps.

The frequency-selective damping isn't an entirely new concept; Koni first introduced it in the late 1990s. The technology alters damping force based on the suspension inputs, achieving a perfect balance between comfort and stability.

Steering Updates

The 2024 Model 3 Highland has also seen changes in its steering mechanism. The variable-ratio steering rack from the previous model remains, which adapts its responsiveness based on the driver's input. However, Tesla has adjusted the ratio, moving from 10.3:1 to 10.6:1, requiring the driver to use more steering input for the same turn. This change targets better predictability and increased stability, especially at higher speeds.

Improved Control Arms

A common issue with the outgoing Model 3 was the front upper control arms. They were susceptible to cracking, which allowed water infiltration, leading to rusting and unpleasant noises. The 2024 Model 3 Highland addresses this with its new forged steel control arm, designed to be more resilient to rust, and offers a sealed ball joint housing to prevent water intrusion.

While this upgrade might be hard to spot, the 2024 Model 3's redesigned steering knuckles enhance driving dynamics by providing greater stability, particularly at higher speeds and during braking, and by minimizing bump steer.

Updated Tire Specifications

The U.S. variant of the Model 3 Highland will sport new standard 18-inch all-season Michelin Primacy tires optimized for Tesla. These tires promise reduced rolling resistance, translating to a slight boost in driving range.

Bushings play a pivotal role in ride comfort and handling. Tesla has revamped the bushings in the front and rear suspension and the rear subframe to minimize noise, vibrations, and harshness, elevating the driving comfort of the Model 3.

While Tesla aims to redefine its reputation for impeccable quality with the 2024 Model 3 Highland, there have been observations of inconsistencies, such as the mis-installation of brake dust shields. However, it's worth noting that these were early-build models from Tesla's Shanghai factory. It's anticipated that production will improve as Tesla irons out potential issues on the production line.

Tesla Increases Price of Model S; Starts Offering Free Lifetime Supercharging

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’s Optimus Robot Learns to Walk Without Vision [VIDEO]

Optimus Falls - but catches itself!

Not a Tesla App

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.

A Look Behind the Curtain

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.
