One thing particular went down within the desert outdoors of Las Vegas this weekend: two EVs took on the Mint 400 for the primary time.
Because the Mint 400 launched again in 1969, automobiles on this iconic desert endurance race have been powered by lifeless dinosaurs. Spectators and race members alike are used to the odor of race gasoline within the air as all the things from V8-motivated Trophy Vehicles to humble Class 11 inventory Volkswagen Beetles fly over jumps, clamber over rocks, and go flat out on the dry lake mattress.
That each one modified in 2024 when a bunch of buddies entered a Rivian R1T and Mint organizer Matt Martelli created an EV Manufacturing class. This 12 months, Chevrolet bought into the sport and entered the Silverado EV ZR2 off-road race truck idea, a modified model of its truck EV. The idea’s reveal comes as Chevy prepares to launch the 2026 Silverado EV Path Boss, its first off-road oriented EV variant, this summer season.
Whereas the Rivian could be very a lot a inventory truck save for the upgraded 35-inch BFGoodrich tires, the Silverado EV bought loads of particular components.
The longer management arms had been taken from the Hummer EV to permit for 13 inches of journey. The air suspension was nixed in favor of dual-coil springs within the entrance — with a spring fee of 1,600 kilos per inch — and single coil springs within the rear. These don’t must help fairly a lot weight and sit at “solely” 978 kilos/inch. Hey, that’s what occurs when a truck weighs almost 10,000 kilos.
The tall springs and 37-inch BFGoodrich tires imply the Silverado EV race truck sits 15 inches off the bottom. Nevertheless, the truck itself is so massive that I initially estimated it to be solely 11 or 12 inches excessive. Such is the facility of proportion.
Additionally taken from the Hummer is the tri-motor system, with two motors within the rear and one within the entrance. Chevrolet says all collectively they produce 1,100 horsepower and 11,500 pound-feet of torque.
Don’t get too jazzed about that torque quantity although. Chevrolet is speaking about wheel torque, which isn’t the measure the business often makes use of to speak about torque. The corporate hasn’t given up all of the numbers to do the mathematics, but it surely’s protected to say the motors produce over 1,000 pound-feet of the stuff. Nonetheless nothing to sneeze at.
Chevy didn’t change the 205 kWh battery. On the street truck that’s adequate for 440 miles, in principle sufficient to race all 4 laps on the Mint 400. Nevertheless, trip peak, tire dimension, tread and air strain, and the grime all take their toll.
Tim Demetrio, Group Supervisor for Off Highway Efficiency at Chevrolet, advised me that in a restricted quantity of testing, the truck averaged .5 miles/kWh within the grime. However he didn’t actually know the way the battery and drive models would react to laborious desert racing.
Not fairly a sq. off
The possibility to see Rivian and the modified Chevy Silverado EV sq. off on the Mint was disrupted by a technicality. Though each automobiles did race, they had been in several courses.
The Rivian competed within the EV Manufacturing class; the Chevrolet, as a automobile that’s presently not supplied to the general public, was within the EV Open class. And every truck was in a category of 1.
What’s worse, the Rivian R1T bought to make two laps of the 73-mile course, the Chevrolet just one lap. It’s widespread for manufacturing automobiles to get fewer laps than the massive Trophy Vehicles, however I hoped each vehicles would duke it out for 2 laps to check each effectivity and charging.
Once I requested Martelli in regards to the discrepancy, he stated,“The Rivian has already raced and accomplished one lap in final 12 months’s race. After we are shepherding in any new class we attempt to ease them into it. We don’t need them to fail. That’s not good for anyone. So we attempt to handle that by giving them a bit bit extra every time.”
Name it the Mint 73
As quickly because the vehicles got here off the beginning line, I instantly ran to the inventory Silverado EV Chevrolet lent me to drive for the weekend.
The primary pit is at race mile 21, and the preliminary a part of the course could be very quick. Groups get to go flat out over a lake mattress, via a number of sections of whoops and sort out some sandy washes. By the point I bought to the primary pit, I had missed the truck.
The second pit space is a fast drive for chase automobiles, however the Chevy solely has to traverse 16 miles of race course. We discovered a spot to park simply in time to see the Silverado EV silently zoom across the nook out of the pit space in a cloud of mud.
The truck crossed the end line with a 40% state of cost. Which means it averaged .6 miles/kWh — a bit higher than the group was anticipating. It took the group 2 hours and 10 minutes to finish the course, so their common pace was about 34 miles per hour. Not too shabby for a giant ol’ truck.
Each driver Chad Corridor and co-driver Mark Stielow had been in good spirits after the race.
“We simply cruised,” stated Stielow “No issues in any respect.”
For Rivian, it’s the Mint 146
After leaving the Chevy, I hightailed it over to the Electrify America chargers to test on the Rivian.
Sure, the Rivian has to cost its 149 kWh battery to make the 2 laps and fortuitously there’s a 350 kW charger only a mere quarter-mile from the race course. The group solely has to enter and exit the course on the identical level.
I arrived at a scene of managed chaos.
The R1T blew an air spring at race mile 50 or so. The group was busy repairing it whereas the truck charged.
Driver Nick Paris advised me they arrived on the charging station with 20% state of cost, placing their lap 1 effectivity on the identical .6 miles/kWh because the heavier Silverado.
He admitted to having a little bit of a lead foot, hitting 110 miles per hour on the dry lakebed. “We noticed the Chevy in entrance of us,” stated co-driver Brett Rieser. “And we stated ‘Let’s go’ and zoooop!” The Rivian made the move and the race was on.
Charged to 90%, the Rivian left on its second lap. The automobile blew a entrance damper, however was solely down for quarter-hour.
The Rivian group arrived on the end line with a ten% state of cost and regardless of pushing the truck to 128 miles per hour on the lakebed, their lap 2 effectivity remained .6 miles/kWh.
With their charging timeout it’s robust to get a median pace, however I might put it at a tad slower than the Chevrolet. Chad Corridor is, in spite of everything, knowledgeable race truck driver. The Rivian group is only a bunch of delightfully nerdy privateers.
Regardless, since each vehicles completed, each are thought of class winners and can take residence a primary place trophy.
The place are Ford, Jeep, Tesla?
Whereas battery density and charging infrastructure imply these electron-powered rigs received’t be aggressive with ICE race vehicles and vehicles, there definitely is room for extra EVs to enter the fray to check their charging pace, vary and sturdiness.
Ford Efficiency — when y’all coming into the Lightning? Hey Jeep, how about coming into a Wagoneer S subsequent 12 months? Heck, I’d even be in favor of Uncle Elon coming into a Cybertruck. GMC can throw within the Hummer, perhaps Porsche may subject a Taycan Cross Turismo. I helped Volkswagen get the ID4 to the end line in Baja within the Mexican 1000 a number of years in the past, so let’s deliver that little man in too. Think about the spectacle of all these automobiles battling for electrical grime supremacy.
