The original i8 model helped launched BMW's i sub-brand, which includes the
electric i3, and serves as a production testing ground for advanced technologies. The i8 relies heavily on carbon fiber for its structure and body, technology which also found its way into the latest 7-Series. The i8 also makes use of a gasoline-electric hybrid drivetrain, with a small gasoline motor powering the rear wheels and an electric motor for the front wheels.
BMW released little information beyond a few photos of the i8 Roadster. The company does not say whether the new model will have a revised drivetrain, or if BMW updated its iDrive cabin electronics to the latest version.
From the photos, however, it looks like it uses a power-retractable hard top, with a panel over the cabin that lifts up and stows away in back. A carbon fiber roof panel would be particularly light, making for little weight shift in the car when stowed.
It is difficult to tell from the photos if the i8 Roadster retains the tiny rear seats of the i8 coupe.
The i8 Roadster will debut during the Los Angeles auto show preview days, running from Nov. 27 to Nov. 30. https://www.cnet.com/roadshow/news/bmw-confirms-i8-roadster-hybrid-debut-for-los-angeles-auto-show/
