Mazda has released U.S. pricing details for the new Mazda3. A modest price increase is in store for the base model, while a fully optioned Mazda3 s gets a price reduction.

Mazda has released pricing info for the all-new 2010 Mazda3. The base version of the car comes with a manual transmission, and will have a price tag of $15,045, up $355 from the current model year. After a destination charge, this price should be more like $15,715.

So what are you paying the extra money for? The entry-level engine is still a 2.0-liter DOHC four-cylinder producing 148 hp. Now, this engine has a 10% increase in fuel economy. However, the new engine is upgraded from a 156 hp 2.3-liter DOHC to the same 2.5-liter MZR found on the Mazda6. It produces 167 hp and 168 ft-lb of torque.

Also getting the 2.0-liter is the Mazda3 i Touring, a sedan with an automatic transmission, stability control, traction control, and Bluetooth. It gets 25 mpg in the city, and 33 mpg highway. Cost of the car, presumably before destination charge, is $18,350.

The Mazda3 s Sport starts at $19,540 with four doors, with the five-door going for $20,030. They get the bigger engine, automatic transmission, 17-inch alloys, and a "Multi-Information Display." The display is a black and white 4.1-inch screen giving out trip data, maintenance messages, system failure alerts, and even information from your MP3 player. Despite the bigger engine, it still gets the same 22/29 mpg as the current model.

Both Mazda3 s units have access to the Technology package. For $1,195 you get keyless entry, push-button ignition, a full-color screen, XM/Sirius satellite radio with six months of service, an alarm, a moonroof, and a six CD changer Bose audio system. It is unclear why a car that is marketed to a younger generation would still offer an expensive, center-console mounted six-CD changer, when they could shave $500 off the price by leaving out the soon-to-be phased out technology.

Base Mazda3 i and s purchasers can also buy the Bose CD changer and moonroof, along with Centerpoint five-channel surround sound, amplifier, noise cancellation, and ten speakers. The price of the audio/moonroof package is $1,395, which seems like a lot of money for what you get.

Mazda claims that in the end, a fully loaded 2010 Mazda3 s Grand Touring four-door will actually cost $240 less than it does now. We built a 2009 model with all of the above, and an auto-dimming rearview mirror with home link for $26,275, including destination charge. That means a 2010 sticker of $26,035.

The Mazda3 i-stop and the Mazda3 MPS will also be on display at the Geneva Motor Show in March.
