Tesla patent shows new Roadster with a hidden 700 kg-downforce rear wing

This one is off-topic for anyone planning home energy upgrades. It's about a Tesla patent for a hidden, retractable rear wing on what looks like the next-generation Roadster, a sports car, not a home product or a rebate program.

The filing describes a two-piece wing that folds flush into the car's body when not in use, then rises up and back to generate up to 700 kg of downforce at highway speeds above 100 mph, aimed at improving high-speed handling and cornering. It can flatten out to cut drag on straight roads, and a computer controls it based on speed, braking, steering, and even GPS, so it can switch into "track mode" automatically at a racetrack. Tesla also built in safety features so the wing folds away if it's hit from behind, say by a cyclist or motorcyclist.

None of this affects home electricity use, weatherization, or available rebates. It is simply a look at upcoming vehicle technology tied to Tesla's Roadster, which the company plans to unveil October 1. If you're weighing home energy upgrades, this news has no bearing on that decision.
