That 1.0L engine was based on the one used in European versions of the Opel Corsa, as "off-the-shelf" as the 1.4L naturally-aspirated. That option should've actually retained in the production version of the Volt since day one, altough probably cooling issues were a reason to not retain it.
After all, if there was really the need for an all-new engine to the Volt, I believe a 2-stroke one would make more sense due to the compactness and lesser dead weight while operating on EV mode. Lesser maintenance would be another advantage.
workaround ideas to discuss among friends: Two-stroke engines: still a viable technology?
