After revisions, the Mazda6 is significantly more comfortable and quiet while retaining much of its driving exuberance that distinguishes it from its midsized sedan competition. This updated 6 feels more expensive than it is. But with the improvements, the car has become slower and less fuel-efficient.
That said, the base four-cylinder engine and responsive automatic transmission make the sedan feel quicker than the numbers alone indicate. The engine returned 28 mpg overall, about average for the class. We have rented a 6 with the optional turbocharged engine and found it both zippier and quieter.
