A few Tesla Cybertrucks were discovered in the wild at California’s Hollister Hills SVRA (State Vehicular Recreation Area). They had RC badging pasted prominently on the sides, front, and also the tailgate.
RC means Release Candidate, the closest version that Tesla is going to deliver to customers. Looking closely at the RC label, “RC_Build Engineering Prototype” was written on the labels to elaborate them a little more.
These RC Cybertrucks were sighted by multiple Tesla enthusiasts around the recreation facility. The guys did not waste time to put their videos on YouTube (watch below).
Tesla employees driving these Tesla trucks hinted that the Cybertruck deliveries are most probably going to start in October. Tesla has already set up the Cybertruck Delivery Event invitation system in its Referral Program but has not announced a confirmed date yet.
According to a Tesla employee testing the Tesla pickup trucks, these Cybertruck RCs are driven all the way from Texas to California for off-road testing at the Hollister Hills SVRA, California.
One interesting thing in these sightings is a closeup look at the Cybertruck’s new wheel design. These are the 20-inch wheels as per the Tesla employees testing the truck. The design of these wheels looks way better than the ones previously spotted or the original ones hidden under the Cybertruck’s patented wheel covers.
Although, these new wheels have been seen on prototypes at Giga Texas before, this time we had a clear look at them in these spottings. Both YouTubers had the chance to take a closer look at the Cybertruck RC engineering prototypes.
Testing the Cybertruck for off-road performance before the launch hints that Tesla is tweaking its software to fit the vehicle. Tesla Model Y has an Off-Road Assist Mode designed for it but the Cybertruck’s design requires its own customized software to assist it in off-roading adventures.
Tesla employees also demonstrated the air suspension of the Cybertruck. According to @MuddyRuttz, there was a significant differential between the lowest to the highest setting. The lowest setting would help the Cybertruck at the dragstrips and the higher setting would be needed during off-roading on difficult terrains.
Another Cybertruck was found parked on the side of the road and a Tesla FSD Beta tester @realwheelieman took a walkaround video of it. Later on, he followed the Cybertruck for a while.
The best part in the following videos comes when the Cybertruck uses its 4-wheel steering to take a sharp right turn. The 4-wheel steering enables the large Tesla Cybertruck to have a short and precise turning radius. However, the 4-wheel steering option will only be available in the top-of-the-line Quad-Motor variant of the Cybertruck.
Since Tesla produces Cybertrucks in Texas, all of these RC prototypes have native manufacturer license plates. One Cybetruck license plate had the number 6EU-828 and the other one had 6EU-886 suggesting all prototypes have numbers in series.
