Chevrolet has only released a teaser photo of the redesigned 2016 Spark minicar so far, but the final product has been hiding in plain sight as the Opel Karl that debuted at the Geneva auto show. The Chevrolet version will have a slightly different look with its brand-specific fascias, but the European-market Karl otherwise provides a good preview of the U.S.-market Spark we’ll see at the New York auto show in a few weeks.
The Calibra holds the title of having been the most aerodynamic car in the world at its 1990 launch, with a drag coefficient of just 0.26. With engines ranging in displacement from 1998 cc to 2498 cc, the car reigned supreme over other makes at the time. Its privileged position as the most aerodynamically efficient car would be held until the end of the 90's when the Calibra was overthrown by new Audi and Honda releases, the A2 and Insight respectively.
It had some crazy mechanical issues. At one point it stumbled and stalled because the carburetor had come loose from the intake manifold and I had to tighten it back down! Another time, my brother was driving it and the brakes failed. Somehow the end of the brake shoe that meets the brake cylinder piston had become worn on one side, causing the piston to slip off the end of the shoe when the brakes were applied, losing braking and squirting fluid all over.
