The Ultimate Tesla Model S Autocross Enduro Race
5 laps of pure adrenaline – Tires and brakes cooking, power limiter kicking in – just a final push to the finish line and…breath again!
Enduro racing, when autocross just isn’t enough. How about 5 continuous laps of autocross? Do you want to see when your car starts to overheat the tires go gooey and brakes begin fading? Experience it all in Enduro!
RELATED: Autocross in a Tesla Model S
There have been complaints about power limitation when tracking a Model S. During the typical ~1 min autocross course the car will not become power limited no matter how hard you punish it. The tires just barely get warm and brakes keep tight, no worries about overheating. A 5 lap Enduro is a different beast entirely. Turbos break, hoses rupture, I have seen brakes glowing and smelled the death scents of tortured ICE cars. This is the Kart Track at the Jackson County Sports Park in southern Oregon and the last autocross event of the year put on by the Siskiyou Sports Car Club (SSCC) is the Fall Enduro.
Jackson County Sports Park- Kart Track
This event is a clockwise 5 lap race around the outside of the track, roughly 3.3 miles total. The ‘grid’ where cars line up to race is near the lower left corner, cars are launched from the green mark and the start/finish line is at the red line. A 2 second penalty is added to your time for toppling a cone (very few out there to worry about) and 10 seconds for putting all 4 wheels in the grass – don’t do that! Racers have the opportunity to practice several laps at a time on Friday and/or Saturday and then just 1 shot at the full 5 lap time trial on Sunday.
The track record for this Fall Enduro event is 3:39.12 set by a TUI formula in the A Modified class, an average of 43.824s per lap and 54mph! My best laps during practice were in the 52.0xxs range but I wasn’t that quick in the race. I drove a different race line from what I had practiced and feel that it was better but I just wasn’t faster (you can watch a set of practice laps here). Earlier this year in the Spring Enduro race I ‘drove’ off of the track once during practice laps so I became a little overly cautious about my braking points during the actual races. With such a heavy car the margin of error is pretty tiny when going from floored at 75mph+ to full brakes and into a turn.
This last fall I managed to break the F Street track record of 4:25.195 by over 2 seconds but then I was ‘ICEd’ by a mere 3/10ths of a second- so close! My local F Street class competition comes from a CTS-V and an M3 . The CTS-V driver has raced for years so I guess I feel ok about ‘letting’ him beat me (technically he was my ‘teacher’ at the race driving school I did, go figure.)

During the race I was pushing close to 75 mph on the straight and used 6.5 kWhr at an average rate of 1.99 kWhr/mi. The S didn’t seem to become noticeably power limited until somewhere around the 4th straight. Through the first 3 laps there was enough power that I could spin the wheels on most of the track so keeping just at the edge of slipping and not dropping too much power can be tricky. Power limiting kicked in on the straights for the last 2 laps and the brakes lost a little confidence by the last lap. For these last laps I pretty much just mashed the throttle to the floor on corner exits, surprising how similar my lap times were…think it means I need to do a bit better in the first 3 laps, read:drive smoother and tighter lines! Driving faster isn’t always faster, taking smooth lines without a lot of slop is usually faster but from an observer it may look slow.
Before I headed out to the track I tried sketching a race line and checking turn radii. After practice and speaking with some locals I tweaked my planned line a bit and ended up with something a little different. My goal was to try and hit all of the apex points that I could on the backside, hopefully something like this
Next Siskiyou Sports Car Club event and the first race of 2015 is the SSCC Spring Enduro, Counter clockwise around the wide curve at the top, past the start line then a hard left and right into the lower loop clockwise up the gut and back around to the finish…
See you there!

Tesla is sending its humanoid Optimus robot to the Boston Marathon
Tesla’s Optimus robot is heading to the Boston Marathon finish line
Tesla’s Optimus humanoid robot will be stationed at the Tesla showroom at 888 Boylston Street in Boston, right along the final stretch of the Boston Marathon today, ready to cheer on runners and pose for photos with spectators.
According to a Tesla email shared by content creator Sawyer Merritt on X, Optimus will be at the Boston Boylston Street showroom on April 20, coinciding with Marathon Monday weekend. The Boston Marathon finishes on Boylston Street, and the surrounding area draws hundreds of thousands of spectators along with international broadcast coverage. Placing Optimus there puts it in front of a massive public audience at zero advertising cost.
Just got this email. @Tesla’s Optimus robot is coming to Boston.

The Tesla showroom is at 888 Boylston Street, between Gloucester Street and Fairfield Street. The final mile of the marathon runs directly along Boylston Street, with runners passing the big stores before reaching the finish line at Copley Square.
Optimus was first announced at Tesla’s AI Day event on August 19, 2021, when Elon Musk presented a vision for a general-purpose robot designed to take on dangerous, repetitive, and unwanted tasks. In March 2026, Optimus appeared at the Appliance and Electronics World Expo in Shanghai, where on-site staff stated that mass production of the robot could begin by the end of 2026. Before that, it showed up at the Tesla Hollywood Diner opening in July 2025 and at a Miami showroom event in December 2025.
Tesla’s well-calculated display of Optimus gives the public a low-pressure first encounter with a robot that Tesla is preparing to soon deploy at scale. The company has previously indicated plans to manufacture Optimus robots at its Fremont facility at up to 1 million units annually, with an Optimus production line at Gigafactory Texas targeting 10 million units per year.

Musk has said that Optimus “has the potential to be more significant than the vehicle business over time,” and separately that roughly 80 percent of Tesla’s future value will come from the robot program. Whether that holds depends on production execution. For now, Boston gets a preview of what that future looks like, standing at the finish line on Boylston Street while 32,000 runners pass by.

Tesla’s golden era is no longer a tagline
Tesla “golden era” teaser video highlights the future of transportation and why car ownership itself may be the next thing to change.
The golden age of autonomous ridesharing is arriving, and Tesla is making sure we can all picture a future that looks like the future. A recent teaser posted to X shows a Cybercab parked outside a home, and with a clear message that your everyday life may soon look like this when the driverless vehicles shows up at your door.
Tesla has begun the rollout of its Robotaxi service across US cities, and the production of its dedicated, fully-autonomous Cybercab vehicle. The first Cybercab rolled off the Giga Texas assembly line on February 17, 2026, with volume production now targeted for this month. Additionally, the Robotaxi service built around it is already running, without human drivers, in US cities.

The Cybercab is built without a steering wheel, pedals, or side mirrors, designed from the ground up for unsupervised autonomous operation. Musk described the manufacturing approach as closer to consumer electronics than traditional car production, targeting a cycle time of one unit every ten seconds at full scale.
Drone footage from April 13, 2026 captured over 50 Cybercab units on the Giga Texas campus, with several clustered near the crash testing facility. Musk has noted that Tesla plans to sell the Cybercab to consumers for under $30,000, and owners will be able to add their vehicles to the Tesla robotaxi network when not in personal use, potentially generating income to offset the vehicle’s purchase cost. That model changes the math on vehicle ownership in a meaningful way, making a car something closer to a depreciating asset that can also earn by paying itself off and generate a profit.
During Tesla’s Q4 earnings call, the company confirmed plans to expand the Robotaxi program to seven new cities in the first half of 2026, including Dallas, Houston, Phoenix, Miami, Orlando, Tampa, and Las Vegas. The service already runs without safety drivers in Austin, and public road testing of the Cybercab has expanded to five states, including California, Texas, New York, Illinois, and Massachusetts.

Tesla announced its Spring 2026 software update, and it’s the most feature-dense seasonal release the company has put out. The update covers twelve named changes spanning FSD, voice AI, safety lighting, dashcam storage, and pet display customization, among other things.
The centerpiece for owners with AI4 hardware is a redesigned Self-Driving app. The new interface lets owners subscribe to Full Self-Driving with a single tap and view ongoing FSD usage stats directly in the vehicle.
Grok gets its biggest in-car upgrade yet. The update adds a “Hey Grok” hands-free wake word along with location-based reminders, so a driver can now say “remind me to pick up groceries when I get home” without touching the screen. Grok first arrived in vehicles in July 2025, but each update has pushed it closer to genuine daily utility. Musk framed the broader vision clearly at Davos in January, saying Tesla is “really moving into a future that is based on autonomy.”
On safety, the update introduces enhanced blind spot warning lights that integrate directly with the cabin’s ambient lighting, building on the blind spot door warning that arrived in update 2026.8.
Dog Mode has been renamed Pet Mode and now lets owners choose a dog, cat, or hedgehog icon and add their pet’s name to the display.
Dashcam retention now extends up to 24 hours, up from the previous one-hour rolling loop, with a permanent save option for any clip. Weather maps now show rain and snow with better color differentiation and include the past hour of precipitation data along the route.
Tesla has now established a clear rhythm of two major OTA pushes per year. As with last year’s Spring update, that cycle started taking shape in 2025 with adaptive headlights and trunk customization. The 2025 Holiday Update then added Grok to the vehicle for the first time. This Spring follows that structure: the Holiday update introduces new architecture, and the Spring update broadens it across the fleet.
Two notable features still did not make it. IFTTT automations, which launched in China earlier this year, were held back from this North American release for unknown reasons, and Apple CarPlay remains absent, reportedly still delayed by iOS 26 and Apple Maps compatibility issues.
Below is the full list of feature updates released by Tesla.
