This Homemade EV Buggy Took on the Rubicon Trail and Won—Twice
If you don't know by now, the Rubicon Trail is a chore. It tests even the most hardcore factory off-road trucks with giant boulders, tight pathways, and the occasional water crossing. You have to be brave to think you can build something from scratch to conquer the 22-miler—either that, or just plain ready to party. I'm not sure which category Nick Dey fits into, but he designed and fabricated this bespoke EV rock buggy in less than seven weeks before traversing the Rubicon the hard way.
Emails and DMs flooded my inbox in the past couple of weeks telling me I should talk with Dey because he's too humble to make a big deal of it. I learned during a quick phone call that not only did he make something special, but he did it on a reasonable budget in practically no time at all. That's the perk of being an expert online shopper and a pro fabricator, as Dey co-owns 80% Off-Road with his pal John Graham.
'We had a weekend wheeling trip in Cougar Buttes near Johnson Valley, and I saw a buggy guy having way more fun than me,' Dey recalled. 'I called my metal supply, got a quote for the tubing, and it was 400 bucks or something. I was like, 'Okay, well, I guess we're doing this.'' Dey only worked on the build during nights and weekends. Still, within less than two months, it was running the Rubicon. Nick Dey
Dey stressed that he never drew up anything in CAD; he just went for it. The buggy started with a seat on the floor, and Dey simply built around that. The result is a roughly 1,400-pound buggy that uses three 48-volt batteries that he bought off Amazon, an HPEVS AC-20 motor that was listed on eBay, and, interestingly, a T90 three-speed manual transmission from a flatfender Jeep (more on that in a bit).
The buggy uses Samurai axles and 35-inch UTV tires to prove not everybody needs one-tons and 40s. Inside those stick axles are 4.57 gears and lockers, which work in concert with the aforementioned transmission to net some serious gear reduction. Dey tells me the electric motor only makes 30 horsepower or so, but thanks to the three-speed gearbox and two-speed transfer case, he's able to eek out every ounce of twist. That's the key to using a small battery pack and compact electric motor. 'Before, it was just a two-speed, so high and low. Then I added the three-speed manual transmission, so essentially, it's a six-speed now.' — Nick Dey
And it is compact, too. Dey likened the motor to a fire extinguisher that weighs about 60 pounds. The unit's diameter is a skosh under 7 inches, while it measures 11.35 inches long. He positioned it under the floor, near the front of the rig, showing just how big the packaging benefit is when you go electric. 'You can really control your weight distribution,' he added. 'It made it a lot easier not having to build around a small-block [V8] or something.'
As for suspension, the buggy runs a three-link front setup and a four-link rear. Ian Lane-Lohse at Wheel Every Weekend valved the Fox 2.0×8.5-inch air shocks, which Dey picked for their affordability. None of it is particularly complex, though it is purpose-built and effective. The same can be said of the entire machine, really. That's a 3,000-pound Smittybuilt XR3K winch on the back. Nick Dey
Dey estimates that he put approximately $10,000 in the whole thing, of which about half came from the EV components. While he notes that electric powertrains aren't 'super cheap,' this build is like 'a drop in the bucket' compared to the Jeeps and whatnot he's owned in the past. Plus, it'll run the entire Rubicon without any fast-charger woes: 'I just plug it into the wall for eight to 10 hours and it's good to go.'
From a napkin drawing to a roller in two weeks and wheeling the Rubicon in seven, the buggy is 'really close to its final form,' Dey told me. It doesn't need to be anything more than it is because it already slays trails in its current form. Dey lives in SoCal, so he can trailer it wherever he wants, wheel it for the day, and drag it back home to plug in for the next trip.
I'm not sure what else you could want from a homebuilt crawler. Ian Lane-Lohse

Connor Zilisch cleared to start NASCAR Xfinity Series race at Daytona less than 2 weeks after breaking collarbone
Connor Zilisch is set to start Friday night's NASCAR Xfinity Series race at Daytona less than two weeks after breaking his collarbone in a fall from atop his car. Zilisch tripped while climbing on top of his car in victory lane to celebrate his win at Watkins Glen on Aug. 10. Zilisch's foot slipped and he fell headfirst onto the ground before he was quickly tended to by medical personnel and taken away on a gurney. But JR Motorsports announced Friday that Zilisch was cleared to race. He will qualify his car for Friday night's race and attempt to race with former Xfinity Series driver and current TV analyst Parker Kligerman on standby if needed. Zilisch had surgery on his left collarbone in the days after the fall. He joked after his surgery that he was given a fall risk bracelet at the hospital. The Xfinity Series was off last weekend. The 19-year-old is atop the Xfinity Series points standings with six wins in 22 races. He's seven points ahead of teammate Justin Allgaier despite starting one fewer race. Zilisch suffered a back injury in a head-on crash while racing for the lead in the waning laps at Talladega in the spring and missed next race at Texas. That crash risk makes it reasonable to wonder if there's a chance Kligerman will get in the car on Friday night at some point simply for precautionary reasons. Zilisch is also widely expected to be announced as a full-time Cup Series driver sooner rather than later. He has a contract with Trackhouse Racing and the team hasn't yet announced its third driver for 2026 after it became known that Daniel Suarez was leaving the team at the end of the season.

Humpy Wheeler, the 'P.T. Barnum of motorsports,' dies at 86
CHARLOTTE, N.C. (AP) — Humpy Wheeler, a pioneering motorsports promoter and former president and general manager of Charlotte Motor Speedway, has died, NASCAR said. He was 86. Charlotte Motor Speedway said Wheeler died of natural causes Wednesday in Charlotte, surrounded by his family. 'Humpy Wheeler was a visionary whose name became synonymous with promotion and innovation in our sport,' said NASCAR chairman Jim France. 'During his decades leading Charlotte Motor Speedway, Humpy transformed the fan experience through his creativity, bold ideas and tireless passion. His efforts helped expand NASCAR's national footprint, cement Charlotte as a must-visit racing and entertainment complex.' Howard Augustine Wheeler Jr. was born in 1938 in Belmont, North Carolina, and gained his first major publicity job with Firestone Tire and Rubber Company. He held several other positions after Firestone shut down its racing program in 1970 and was hired at Charlotte Motor Speedway by owner Bruton Smith as president in 1975. He became a transformative figure in promoting racing and was known as the 'P.T. Barnum of motorsports' for flashy pre-race stunts, elaborate productions and sparing no expense in ensuring fans had the most enjoyable experience possible at his events. Wheeler earlier this year was named winner of NASCAR's prestigious Landmark Award for Outstanding Contributions to NASCAR, to which he'd have been inducted into the Hall of Fame next year. 'Humpy's contributions to and accomplishments in NASCAR are without parallel. The breadth and depth of his legacy, and those whom he influenced, assisted and mentored, cannot be overstated,' said Winston Kelley, executive director of the Hall of Fame. "Frequently adding new dynamics to the sport, Humpy's visionary leadership and creativity helped shape today's fan experience. 'Through his innovative promotions and stunts, Wheeler's contributions expanded NASCAR's national and international presence during the 1990s and early 2000s, solidifying Charlotte as 'NASCAR's Home for Racing.'' Wheeler mentored 'hundreds, if not thousands,' of people throughout his life, Kelley said, including inaugural NASCAR Hall of Famer Dale Earnhardt and Landmark Award recipient Janet Guthrie. Wheeler spent 33 years running Charlotte Motor Speedway. His innovation and pre-race extravaganzas recreated numerous military operations — including the invasion of Grenada — that made the facility a gold standard in NASCAR. He promoted school-bus races during the week, grassroots series for young aspiring racers, stunts and even the 'Robosaurus,' a towering, fire-breathing, car-crunching mechanical robot. Wheeler and his boss, the late Smith, grew Charlotte Motor Speedway into the ownership group Speedway Motorsports Inc., which acquired multiple race tracks that play a pivotal role in American motorsports today. Charlotte was the first track to build condominiums on site, built a restaurant overlooking the race track and was the first speedway of its size to install lights for night racing. 'Charlotte Motor Speedway was blessed to have a leader in Humpy Wheeler who can only be described as ONE of a kind,' the speedway said in a statement. ' For more than 30 years, Humpy was a promoter's promoter at Charlotte Motor Speedway. Alongside our founder Bruton Smith, Humpy pushed the speedway to new and greater heights — establishing the famed 1.5-mile superspeedway as not only the most innovative facility in NASCAR for fan, partner and competitor amenities, but also one of the most progressive in all of sports. 'Humpy's engaging smile and flair for promotion were legendary, and his impact on every stakeholder in motorsports will be long-lasting. Humpy not only made his mark with publicity, but also with a laser-focus toward the fans," the speedway continued. 'He would often tell his staff to pay attention to 'the three Ts — tickets, traffic and toilets,' in order to ensure fans have the best possible experience. He would also say it was our job to put a little 'technicolor in people's black-and-white lives.'" Wheeler retired from Charlotte Motor Speedway and Speedway Motorsports in 2008 after a bitter falling out with Smith, but remained active in motorsports through his own consulting company and was on the voting panel for the NASCAR Hall of Fame. He is survived by his wife, Pat; daughters, Traci and Patti; son, Trip; and four grandchildren. Funeral arrangements are pending and the family request donations be made in Wheeler's name to the Belmont Abbey College Motorsports Management Program, which Wheeler was instrumental in launching more than 20 years ago. ___ AP auto racing: Jenna Fryer, The Associated Press

Hybrid vehicles retain resale value despite market volatility: Cox Automotive
Recent data from Cox Automotive has highlighted that hybrid vehicles are demonstrating a notable capacity to preserve their value during periods of market instability. In a comparison from November 2022, the difference in residual values between hybrid and electric vehicles (EVs) was marginal, with hybrids at 90% and EVs at 88%. Switch Auto Insurance and Save Today! Great Rates and Award-Winning Service The Insurance Savings You Expect Affordable Auto Insurance, Customized for You Fast forward to July 2025, and the scenario shows hybrids less than two years old maintaining 68% of their original cost new (OCN), a 22% reduction, whereas EVs of comparable age witnessed a sharper decline to 49%. The ability of hybrid vehicles to sustain their value is particularly striking in light of recent legislative adjustments that have affected the financial benefits of owning a hybrid, the company said. Since April, hybrid car owners with vehicles registered post-2017 are now subject to the same vehicle excise duties as those applied to petrol and diesel cars. Moreover, the Zero Emission Vehicle Mandate is set to gradually eliminate the sale of hybrid vehicles by 2035. Despite these developments, the UK market's interest in hybrid vehicles has not waned. Joint research from Regit and Cox Automotive shows that 29% of drivers are considering a hybrid for their next car purchase. This is corroborated by the latest statistics on new car registrations, which indicate a 31.5% increase in PHEV [plug-in hybrid electric vehicle] registrations and a 6.5% increase in HEV registrations on a year-to-date basis. Cox Automotive Europe insight director Philip Nothard said: 'Hybrid vehicles offer drivers an alternative, cost-effective solution for buyers who want to transition to a more sustainable form of transport but have concerns around range or infrastructure. 'This is driving demand for them in the used car market, which helps support stronger residuals. Additionally, these vehicles have a lower cost of entry than their electric equivalents, which means they hold their value better when entering the used market.' Regarding hybrid vehicles, Nothard added: 'They deliver a clear lifetime cost advantage over internal combustion and electric vehicles, making them an attractive option for buyers hesitant or cautious about making the full electric transition. Yet, evolving government policy could undermine this potential if hybrid ownership becomes less financially viable.'
