Engine

The Mazda 3’s 2.5 DOHC 4 cyl. produces 34 more horsepower (186 vs. 152) and 41 lbs.-ft. more torque (186 vs. 145) than the Impreza’s 2.0 DOHC 4 cyl.

Fuel Economy and Range

An engine control system that can shut down half of the engine’s cylinders helps improve the Mazda 3 Premium/Hatchback/AWD’s fuel efficiency. The Impreza doesn’t offer a system that can shut down part of the engine.

Transmission

The Mazda 3 comes standard with an automatic transmission, for driver comfort, especially in the city. Automatic costs extra on the Impreza.

A six-speed manual is no cost option on the Mazda 3 Hatchback, with closer gear ratios for better performance and a lower final drive ratio for quieter highway operation, less engine wear and better fuel mileage. Only a five-speed manual is available for the Impreza.

Brakes and Stopping

For better stopping power the Mazda 3’s front brake rotors are larger than those on the Impreza:

Suspension and Handling

For a smoother ride and more stable handling, the Mazda 3’s wheelbase is 2.2 inches longer than on the Impreza (107.3 inches vs. 105.1 inches).

For better handling and stability, the track (width between the wheels) on the Mazda 3 is 1.1 inches wider in the front and 1.4 inches wider in the rear than on the Impreza.

For better maneuverability, the Mazda 3’s turning circle is .6 feet tighter than the Impreza’s (34.8 feet vs. 35.4 feet).

Chassis

The Mazda 3 Sedan is 6.5 inches shorter than the Impreza Sedan, making the Mazda 3 easier to handle, maneuver and park in tight spaces.

Cargo Capacity

The Mazda 3 Sedan has a larger trunk than the Impreza Sedan (13.2 vs. 12.3 cubic feet).

Ergonomics

When two different drivers share the Mazda 3 Preferred/Premium, the memory seats and mirrors make it convenient for both. Each keyless remote activates different, customized memories for the driver’s seat position and outside mirror angle. The Impreza doesn’t offer a memory system.

The Mazda 3 Premium has a standard heads-up display that projects speed and warning light readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Impreza doesn’t offer a heads-up display.

The Mazda 3’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Impreza’s rear power window switches have to be held the entire time to open or close them fully.

The Mazda 3 Hatchback/Select/Preferred/Premium’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. The Impreza’s manually variable intermittent wipers have to be constantly adjusted.

When the Mazda 3 Preferred/Premium is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Impreza’s mirrors don’t automatically adjust for backing.

The Mazda 3 Hatchback/Select/Preferred/Premium’s standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The Impreza doesn’t offer dual zone air conditioning.

Model Availability

The Mazda 3 is available in both front-wheel drive and all-wheel drive configurations. The Impreza doesn’t offer a two-wheel drive configuration.
