Despite Volkswagen's fidelity to diesel, the 2013 Jetta Hybrid doesn't merely humor Americans' hankering for hybrids, but makes a sincere effort to compete. Cars.com reviewer Mike Hanley says a turbocharged 1.4-liter four-cylinder engine, assisted by an electric motor with a lithium-ion battery pack, boasts gas mileage rivaling top competitors.

Still, could acceleration and braking issues that that make the Jetta Hybrid feel slow and clumsy prevent its rise to success? Read Hanley’s review and decide.
