UK diesel sales see drastic decline amid Tesla and electric cars’ meteoric rise
Electric vehicles are becoming increasingly popular in the United Kingdom, while cars that are powered by diesel are seeing a decrease in demand. These statistics are based on figures released by The Society of Motor Manufacturers and Traders (SMMT), a trade association for the automotive industry in the UK.
“Alternatively fueled vehicle (AFV) registrations reached a record market share, with more than one in 10 cars joining UK roads either hybrid, plug-in hybrid or pure electric,” the SMMT said. Compared to the month of November 2018, Battery Electric Vehicles (BEV) saw a 228.8% increase in sales, and became more than three times as popular in terms of market share, moving from 0.9% in 2018 to 3.0% in 2019, according to data released by the SMMT.
Inversely, Diesel plummeted dropped over 27% from what the UK saw in 2018. While these cars are still notably more popular than BEVs, Plug-in Hybrid Electric Vehicles (PHEV), or Hybrid Electric Vehicles (HEV) in terms of overall sales, their numbers are falling at a steady rate. Last month, only 36,941 diesel vehicles were sold, compared to 50,750 for the same month in 2018.
This decline in diesel sales could be attributed to former Chancellor of the Exchequer, the Royal Treasury, Philip Hammond’s decision to tax older diesel-powered vehicles last year. The tax charges £12.50 daily to diesel drivers in central London and took effect in April 2019. Next year, vans, buses, and other heavy pollution-emitting vehicles will see guidelines that may bring additional taxes, according to The Guardian. Weak business in the automotive market, decreasing consumer confidence, and uncertainty regarding clean air zones could also be attributed to the decreasing sales of diesel cars.
It is no secret the appeal of electric cars has been spreading across the world. However, the need to ween off the dependence on petrol-powered vehicles is coming from the UK’s goal to phase-out fossil fuels as an energy source for cars in the coming years. In Scotland, the goal is 2032, while in England, Wales, and Northern Ireland, the goal is a bit more conservative at 2040.
Tesla’s presence in the UK has become more notable as of late. The Model 3 won the “Car of the Year”, “Best Electric Car”, “Best Company Car”, and “Best Safety” awards from the prestigious automotive magazine Parker’s Car Guides, who were impressed with the vehicle in a multitude of ways. Parker’s representatives said the vehicle was “capable, likable, and extremely good to drive,” a description that seems to be used quite often when talking about Tesla’s most affordable electric car. It was also named the third best-selling car in the UK by the SMMT.
The SMMT’s report that diesel vehicle sales are falling while electric car sales are rising may be a sign that those in the UK are recognizing the economic and environmental advantages of battery-powered transportation. Even some who are interested in high-performance vehicles are now finding their preferences shift to electric propulsion, as the instant torque from a premium EV like a Tesla gives vehicles an exhilarating experience.

Tesla has started to deploy the 2026 Summer Update to owners across its fleet, and among the biggest changes are improvements to Navigation, a new startup animation for the Model 3 and Model Y, Caraoke scoring, and new capabilities for Grok.
As the update has started making its way to some cars, we can now see a few of the features operating in real-time. We will show you what some of the new features look like in this article, along with some additional details on what changed.
Not all of the new features in the 2026 Summer Update have quite made an appearance, but some of them have, so we’ll show those here:
New Animation Screen for 3/Y
Tesla is rolling out a new startup animation for Tesla Model 3 and Model Y owners. This is present in Launch Edition and Performance Model 3 and Model Y, but other trim levels do not have anything like this.

Owners can adjust the color associated with the startup animation to suit their preferences. It is a surprise that more automakers do not focus on this animation for their vehicles; it can be a great first impression piece and make the car immediately feel more luxurious.
Tesla has included this on more premium trims, but it is nice to see it on the Model 3 and Model Y.
Grok Improvements
Grok can now adjust more things in the car outside of the Navigation system. Now, drivers can adjust anything from climate to driving settings by simply speaking to the AI assistant in the car:

You don’t even have to push a button, either. Instead, you can just say “Hey, Grok,” if you have it enabled. That feature rolled out with the 2026 Spring Update just a few months back.
-
This is a great feature, especially pertinent for the Robotaxi platform, as there will be no buttons inside the Cybercab when it eventually starts giving rides to the public. It also broadens Grok’s capabilities, which were relatively limited in terms of vehicle setting adjustments beforehand.
Tesla briefly offered one Robotaxi part in its Parts Catalog for your personal car, only to remove it just a short time after it was first noticed.
Tesla’s Robotaxi camera washer apparatus was briefly available for purchase on the company’s Online Parts Catalog. The camera washer was first noticed on Model Y Robotaxi vehicles about six months ago in Austin.

First noticed by Not a Tesla App, the Camera Washer entries appeared for the new “Juniper” Model Y under a category called “Halo,” which has also now disappeared. Interestingly, Halo probably is related to Tesla’s internal “Project Halo,” which was a project that aimed to retrofit customer-owned Model Ys into functional Robotaxis.
This hardware addition would likely be required for the vehicle to operate as a Robotaxi, as the Camera Washer seems to be a non-negotiable part of the vision-based system Tesla utilizes for self-driving efforts.
However, this part has since been removed and is no longer visible on the EPC.
-
Now the true question lingers: Why would Tesla add this Camera Washer to the Model Y parts catalog? Is it planning to make it available for owners to utilize on their own cars for personal use, or will it become a prerequisite for Robotaxi operation in customer-owned cars?
While discussing the upgrade options for Hardware 3 vehicles during the Q1 Earnings Call, Tesla CEO Elon Musk had said that the company could establish small, satellite shops that would upgrade cameras and self-driving computers. Perhaps this same strategy could be utilized for vehicles that want to be included in Robotaxi but do not have the correct hardware.
AI4 is currently represented as capable of unsupervised self-driving, and the same was said about HW3 at one point, only for Tesla to admit last quarter that it would, unfortunately, not be possible. Perhaps AI4 vehicles might need this camera washer as a prerequisite, just as HW3 cars will need that camera and computer upgrade.
This could be the first hint of that’s where we are headed.
Tesla has started rolling out a broader change to the ride experience for its Robotaxi fleet by silencing turn signals, but the change is certainly polarizing.
Tesla has generally made it clear that its purpose-built ride-hailing platform, Robotaxi, will cater to the rider in nearly every way possible. This includes having climate preferences, music, and other personal settings loaded up in the car as the rider enters.
But Tesla is taking it a step further by muting turn signal chimes altogether, a change that appears to be a way to make the ride more peaceful:
Tesla has finally turned off the blinker/turn signal noises in their Model Y Robotaxis.
This is a small update, but will definitely be noticeable for riders. It didn’t really make much sense to leave the turn signal sound on when it’s Unsupervised. pic.twitter.com/ITwx60PAMO

However, there are a handful of people who are not thrilled about this change. Turn signals are a conditioned part of the human mind for those who ride in a car regularly.
-
Taking a turn without one feels strange and odd, and not hearing it click while activated could set off some alarms for riders, who might use the noise as confirmation that other drivers know of their intention to turn.
I kind of like it being on, threw me off when riding with Zoox who has had it disabled
— Dan Burkland (@DBurkland) July 27, 2026
Turn signal noises are still audible in customer cars, so if you use FSD in your personal vehicle, you will still hear the turn signal.
The move is certainly one that is unique, but not one that separates it from other ride-sharing services. In a normal car, the clicking sound confirms to the driver that the blinker is active. In a fully driverless Robotaxi, that feedback serves no purpose for passengers, other than peace of mind.
