Porsche is now directly offering a Manthey-Racing upgrade for the 911 GT3, meaning the mods won't void the manufacturer’s warranty. The upgrade manages to shave four seconds off the 911 GT3's Nürburgring lap time without resorting to simply adding more power.

A Polestar 5 is coming in 2024 to take on the Porsche Taycan and high-end versions of the Tesla Model S, and new patent drawings likely reveal the design. The Polestar 5 is a mid-size hatch and Polestar first previewed the design in 2020 with its Precept concept.

Buick has also previewed its future with some concepts. There's the Electra-X which previews an electric vehicle for China, and the Wildcat EV which features design elements bound for Buick EVs sold in the U.S.
