http://PutnamMazda.com/showroom/index.htm 650-558-5685 The new Mazda 6 has one of the more striking designs in the class. Under the sleek skin there's a new 184-horsepower, 2.5-liter four-cylinder engine that provides spirited performance along with pleasantly subdued noises and an impressive 30 mpg combined fuel economy estimate. Mazda will introduce a turbocharged 2.2-liter diesel four-cylinder later in the model year that should return at least 40 mpg highway while offering stronger acceleration than the base gasoline engine. What separates the 2014 Mazda 6 from most of the pack is its sporty, involving personality.
