Tesla Battery Day: a raft of tech advances will deliver cost reductions worth waiting for
We’re used to extremely ambitious (not to say unrealistic) timelines from Tesla—a new Terafactory in a few months, a fleet of Robotaxis before the end of the year—so Elon Musk’s measured, conservative predictions at the long-awaited Battery Day event caught the mainstream press on the wrong foot. “In three years…we can do a $25,000 car… Read more »

Startup led by Tesla alums aims to build electric RVs
As is the case with a legacy vehicle, towing a trailer with an EV greatly reduces range—as John Voelcker found in his recent test of a Ford F-150 Lightning (see the latest issue of Charged), towing can reduce range by 40% or even more. But what if the trailer had its own electric powertrain? That’s… Read more »
