Tesla has pushed the planned public demo of its next-generation Roadster to August or later, according to a report from The Information citing four people with knowledge of the program. It marks yet another delay for the vehicle first unveiled as a prototype nearly nine years ago.

The demo, expected to take place in Texas, is meant to showcase the SpaceX cold gas thruster system that Tesla claims will allow the Roadster to achieve extreme acceleration and even lift off the ground.

In the Electrek Podcast, we discuss the most popular news in the world of sustainable transport and energy. In this week’s episode, we discuss Tesla Semi nailing a big test, BMW iX3’s range impressing in a new test, Xpeng catching up to Tesla, and more.

Xpeng’s head of autonomous driving told Electrek that the company is spending roughly 300 million RMB (~$41 million) per month on AI training alone and believes it has already reached parity with Tesla’s FSD v13 — with v14 within reach before the end of summer.

I sat down with Dr. Xianming Liu, head of Xpeng’s General Intelligence Center, the day after he delivered a keynote at CVPR 2026 in Denver — sharing the stage with Tesla’s Ashok Elluswamy and leaders from Nvidia and Waymo at one of the world’s top computer vision conferences.

UK-based EV conversion specialist Electrogenic has converted five of Jason Momoa’s cherished vintage vehicles to electric power — including three 100-year-old Harley-Davidson motorcycles reimagined as plug-in hybrids. The builds are featured in Season 2 of Momoa’s HBO documentary series On The Roam, streaming now.

The project includes two extremely rare classic Land Rovers converted to all-electric drive with 150+ miles of range, a battery-equipped off-grid camping trailer, and the three Harleys that can switch between electric, petrol, and combined hybrid power on the fly. Electrogenic is now selling conversion kits for both the Land Rovers and the Harleys.
