The Cruze brings a compact European sensibility to the American market along with a set of distinctive powertrain options. A 1.8-liter four-cylinder is standard and a turbocharged 1.4-liter four is available, as is a new 2.0-liter turbo-diesel. Although the base engine is downright dreary, the turbo model adds some much-needed pep to the Cruze, while the Eco and the diesel add efficiency.
