With total worldwide sales now eclipsing 3.5 million units, the 
Mazda3 has racked up an enviable track record during its decade-long run
 to glory. Over the course of two generations, this engaging C-segment 
road warrior has become the automaker's highest-volume global offering 
as well as the firm's most important player here, where it currently 
accounts for over 40 percent of Mazda's annual U.S. sales. But in the 
super-competitive compact realm where the Mazda3 must face off against 
prime rivals like the Ford Focus and Honda Civic, Mazda wanted to stretch the envelope of the upcoming Gen III iteration in a major way.
 Due in showrooms this September, along with its Mazda3 Sedan
 sibling, this now even flashier 5-door matches aggressive "Kodo" 
styling language and a well-finished passenger compartment with the full
 complement of weight-saving/efficiency-enhancing Skyactiv technologies 
previously introduced on the CX-5 and Mazda6.
 We recently slipped behind the wheel of two Hatchback
 prototypes to see how well this new mix came together. While final 
judgment will be reserved for a true production unit, we can 
unequivocally confirm the latest Mazda3 incarnation does boast a full 
measure and more of Mazda's iconic zoom-zoom character.
 

 In
 keeping with tradition, the 2014 Mazda3 lineup continues to be split 
into "i" and "s" members for both body configurations. Motivating the 
Mazda3 i SV (Sedan only), Sport, Touring and Grand Touring models is a 
slightly tweaked version of the existing 2.0-liter/155-horsepower 
Skyactiv-G 4-cylinder engine found in the 2013 Mazda3 that now makes 150
 lb-ft of torque -- up from 148 -- and has better mid-range punch. 
Mazda3 s Touring and Mazda3 s Grand Touring models replace the existing 
167-horsepower/2.5-liter MZR engine with the more potent 
184-horse/2.5-liter Skyactiv alternative that also appears in the 2014 
CX-5 SUV and Mazda6.

 While
 the 2.0-liter can be backed by either a 6-speed manual or 6-speed 
automatic in all "i" trims, the 2.5-liter only comes with the latter 
unit that also includes steering-wheel mounted shifter paddles. The 
2.0-liter Hatchback has already earned an official 40-mpg EPA highway 
rating with either transmission. At the moment, Mazda is projecting the 
2.5-liter version will get 37 mpg on the highway, or 39 mpg on Grand 
Touring models fitted with active grille shutters and the innovative 
i-Eloop regenerative engine-braking system that's part of a Technology 
Package available only on the top-line model.
 Intent on creating a
 vehicle that would resonate more intensely with owners on both visual 
and visceral levels, Mazda complemented the 5-door's sleeker new 
sheetmetal and edgier fascia detailing with an even stouter but lighter 
core structure. Comprised of 60 percent high-strength steel, it endows 
the car with 31 percent greater torsional rigidity. Similar gains are 
found in the new Sedan, which like the Hatchback weighs about 100 pounds
 less than the existing 4-door. Wider, lower and marginally shorter than
 its 2013 counterpart, the new Mazda3 5-door complements 2.4 inches of 
added wheelbase with expanded front (0.8-inch) and rear (1.4- to 
1.8-inch depending on wheel/tire fitment) track specs. Collectively, 
that dimensional rethink helps elevate its curbside aggression index 
while enhancing the car's overall dynamic potential.
 Keen to show
 off its newest player to full advantage, Mazda turned us loose on an 
appropriately challenging route that snaked through the Angeles National
 Forest outside of Los Angeles. Despite their significant weight drops, 
we'd characterize straight-line acceleration of the manual-equipped 
2.0-liter and auto-equipped 2.5-liter versions we drove as 
enthusiastically spirited rather than blisteringly quick. However, 
there's little to fault about the speed or execution of cog changes 
performed by either of the Skyactiv transmissions.
 

 The
 true strong suit of this new Mazda is its ability to confidently carve 
through even the most challenging corners. The robust foundation teamed 
with a well-sorted suspension delivers impressive compliance and control
 while new electrically-assisted power steering proved both precise and 
rich in positive feedback. There is one key differentiator in the mix: 
All Mazda3 i models are fitted with H-rated 205/60 tires on 16-inch 
steel or alloy wheels, while 3 s Grand Touring variants roll on W-rated 
215/45 all-season performance rubber wrapped around 18-inch alloys. 
Although it exacts a modest penalty in absolute ride comfort, the 
stickier but stiffer Plus-2 upgrade gives the 2.5-liter Grand Touring a 
decidedly more planted feel when you're taking on the twisties.
 Like
 its exterior, the passenger compartment of the new Mazda3 has a more 
sophisticated look and feel, whether appointed in cloth, leatherette or 
real leather. Repositioned A-pillars enhance forward sightlines while 
redesigned front buckets serve up greater support and comfort. Despite 
swapping a bit of legroom for marginally more knee space, the rear bench
 of the Mazda3 Hatchback can still handle a pair of average-size adults.
 Drop its 60/40 split back into a near-flat folded position and the 
20.2-cu ft cargo bay expands into a 47.1-cu ft mini cave.

 Last
 but far from least, the new Mazda3 features a load of new "class-above"
 technology, including the latest incarnation of the automaker's HMI 
(Human Machine Interface) on select models. This "heads-up" approach to 
cockpit design nets a small pop-up Active Driving Display screen 
directly ahead of the driver that shows speed, navigation instructions 
and active safety data as well as a 7.0-inch color touchscreen, which 
for the first time is located on top of the dash rather than in the 
center stack. Paired with Mazda's console-mounted multifunction 
Commander, it affords quicker, easier and less-distracting access to 
various navigation and infotainment functions.
 The 2014 Mazda3 
makeover also brings a host of new and more user-friendly connectivity 
features, including the ability to perform updates via a 
Bluetooth-paired smartphone. The system can now read aloud and respond 
to social, text and e-mail messages, and access thousands of Internet 
radio stations, audio books and other apps using Mazda's first 
implementation of the powerful Aha aggregator app.
 A similar leap
 forward has occurred in the active safety arena. In addition to 
features like Blind Spot Monitoring and Rear Cross Traffic Alert that 
are standard on Touring and above trims, the optional Technology Package
 for the Mazda3 s Grand Touring brings Lane Departure Warning, High Beam
 Control and two segment-exclusive features -- Radar Cruise Control 
& Forward Obstruction Warning and Smart City Brake Support.
 Pricing for the 2014 Mazda Mazda3
 lineup will be announced closer to its arrival in showrooms. For the 
moment, all Mazda execs have confirmed is that it will open below 
$17,000 plus destination. All we can confirm is that the new Mazda3 is 
destined to become even more of a power player in the ongoing C-segment 
car wars.
