For those unfamiliar, the Sonnet was a small sports coupe first built by Saab in 1955 and again in the mid-60s until 1974. This new Sonnet would have been built on the same Phoenix platform as the new 9-3 with a design inspired by the stunning Aero-X concept. Power would have also supposedly come from "various versions of Mini's current 1.6-liter turbocharged" gasoline engine. Plans were also in place to build a all-wheel-drive performance version with an electrically-powered rear axle for improved handling. Overall, this sounds like a great plan that would have been just the thing to help Saab expand its lineup while drawing upon its past.
