The Ultimate Tesla Model S Autocross Enduro Race

Published

on

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.

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.)

Vehicle                                   Lap1      Lap2      Lap3      Lap4      Lap5       total time

’13 Cadillac CTS-V Coupe   53.146   52.684   52.265   52.502   51.976     4:22.573

’12 Tesla Model S                52.145   52.318   53.033   52.712   52.704     4:22.912

’13 BMW M3                         53.393   53.026   53.264   53.400   53.091     4:26.174

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 has brought perhaps the coolest interior feature to its cars in a new update that is rolling out to vehicles now.

The feature will require a newer vehicle that has interior ambient lighting, which is present on the new Model S, Model X, Model 3 “Highland,” and Model Y “Juniper.” The Cybertruck also has ambient lighting strips throughout.

Tesla Model Y’s ambient lighting design changes revealed in leaked video

With the Version 2025.26+ Software Update, Tesla is rolling out a new “Sync Accent Lights w/ Music” feature, which is available on the Tesla Toybox:

To enable the feature, you’ll access the Toybox, choose “Light Sync,” and then choose “Sync Accent Lights w/ Music.”

Although it does not improve the performance of the vehicle, it is yet another example of Tesla making one of the coolest cars out there. This is truly a cool add-on that can be used to impress your friends and family.

Elon Musk’s artificial intelligence startup xAI and the Musk Foundation have been supporting Memphis-Shelby County Schools with HVAC repairs and facility upgrades, while also funding youth programs for students in the area. 

Reports of xAI and the Musk Foundation’s work were recently posted by local news media.

xAI’s school visits lead to facility repairs

Representatives from xAI visited John P. Freeman Optional School, Fairley High School, and Westwood High School, all of which are located near its Colossus supercomputer site, to assess HVAC systems, plumbing, gym facilities, and athletic fields. The visits resulted in a list of priority repairs, some of which were completed in April and May.

In addition to the repairs, xAI also shared a number of initiatives that are planned for students in the area, as stated in a Commercial Appeal report.

“xAI is working on providing STEM workshops for local students, donating equipment to technical training programs, and supporting job fairs to boost employment opportunities. These initiatives reflect xAl’s commitment to fostering education and economic growth in Memphis,” xAI noted in a statement.

Musk Foundation donation

Apart from xAI, the Musk Foundation also donated $350,000 to the Boys & Girls Clubs of Greater Memphis, enabling the reopening of two club sites located at Booker T. Washington High School and Westwood High School. Both locations had closed earlier this year due to lapses in funding. As per xAI, the Musk Foundation’s donation allows clubs to reopen for almost 1,000 students. 

The donation will fund staffing, supplies, and transportation, among others. “Kids are the future of humanity,” Elon Musk said in a statement, adding that students need “every chance to shoot for the stars.”

“We’re honored to support the Boys & Girls Clubs of Greater Memphis in reopening these sites, giving kids in underserved communities the tools to build brighter futures,” Musk said.

The gift was praised by local officials, including Boys & Girls Clubs board chair Michael Garriga, who stated that the “commitment will ensure the youth of our community have the opportunities they need to develop their skills and talents to become successful students and future citizens.”

EV fans urge Tesla to acquire Unplugged Performance for edge in fleet and security industry

Unplugged Performance has built a name for itself by producing performance upgrades for Tesla vehicles.

A growing number of Tesla enthusiasts and longtime community voices are calling on the electric vehicle maker to acquire Unplugged Performance, a California-based aftermarket company best known for tuning Tesla vehicles and developing specialized government fleet solutions under its UP.FIT division.

The idea was once considered a niche proposal among EV fans, but it is now gaining serious attention not just as a performance play but as a strategic move to deepen Tesla’s roots in the fleet and security industry. 

A strategic fit

Unplugged Performance has built a name for itself by producing performance upgrades for Tesla vehicles, from track-optimized components to visual and aerodynamic upgrades. But in recent years, its UP.FIT division has pivoted toward a more functional future by outfitting Tesla vehicles like Model Ys for police, military, and government use.

That work has sparked growing calls for closer collaboration with Tesla, especially as the EV maker increasingly leans into autonomy, AI, and fleet services as core components of its next chapter.

“I posted this four years ago, but I think it’s more true now than ever,” wrote Whole Mars Catalog, a well-known Tesla investor and FSD Beta tester, on X. “Tesla should buy Unplugged. But not just as a Performance division. What they are doing with UP.FIT unlocks large government and commercial fleet purchases that can improve utilization.”

Tesla fans such as shareholder Sawyer Merritt echoed the sentiment, calling Unplugged a “great fit within Tesla.” adding, “They are literally located directly next to Tesla’s design studio in Hawthorne.”

Enabling the next wave

Supporters of the idea noted that integrating Unplugged into Tesla’s corporate structure could help accelerate the adoption of autonomous technologies in government sectors. With UP.FIT patrol cars already in use across some U.S. police departments, Tesla fans envisioned a future where self-driving Teslas could potentially revolutionize law enforcement, search-and-rescue, and public service logistics.

“Just imagine how autonomous patrol cars could transform policing and bring us into a safer future,” the veteran FSD tester wrote.

The benefits could also extend to Tesla’s existing consumer base. “They also have some incredible products in the works that I think will appeal to many ordinary Tesla drivers — not just those looking for performance or mods. Stuff that’s so good it should have come straight from the design studio next door,” Whole Mars Catalog noted.

Unplugged Performance, founded in 2013, shares not just a product vision with Tesla, but also geography. Its Hawthorne headquarters sits directly adjacent to Tesla’s design studio, and the two companies have maintained a close working relationship over the years. The aftermarket firm has long positioned itself as a “mission-aligned” partner to Tesla.

In response to the recent calls for acquisition, Unplugged Performance acknowledged the support from the community. “Our very existence is to support the Tesla mission with @UpfitTesla and @UnpluggedTesla,” Unplugged CEO Ben Schaffer posted on X. “We love working with Tesla and are grateful for the community’s support since 2013!”
