The Chevrolet Sonic is a wholesale improvement over its predecessors, the Aveo and Metro, but in its eight years on the market, it’s only been facelifted once. Although still fun to drive, it’s outclassed by newer, more efficient competitors. Add to that significant showroom in-fighting between the Sonic and the more popular Trax crossover and you get a recipe for failure. Chevrolet will likely not replace the Sonic, instead marketing the sub-$20k Trailblazer to budget-oriented buyers.
