Listen Later

The numbers are in and they are all bad for Tesla fans – the company sold just 5,000 Cybertruck models in Q4 of 2025, and built some 30% more "other" vehicles than it delivered. It just gets worse and worse, on today's tension-building episode of Quick Charge!

We've also got day 1 coverage of the 2025 Electrek Formula Sun Grand Prix, reports that the Tesla Optimus program is in chaos after its chief engineer jumps ship, and a look ahead at the fresh new Hyundai IONIQ 2 set to bow early next year, thanks to some battery specs from the Kia EV2.
