Great designs evolve over time, but always hark back to a central theme that defines the brand. So it is with the third-generation MX-5. In fact, it looks more like the original Miata than the second-generation model. The overall design is somewhat slab sided and both taller and more rounded at the front end than previous versions. But the ovoid shape of the grille is pure Miata. (The grille on the hardtop models is brightened with a delicate chrome ring around its circumference.) This larger-than-before opening moves more cooling air through the radiator and around the larger engine and combines with a pronounced air dam across the bottom of the lower opening to give the Miata's face a strong chin. So what if it brings to mind a largemouth bass when viewed straight on? It does what it's supposed to do. Compound, projector-beam headlights live in small housings deeply recessed and near to the car's centerline, which emphasizes the Miata's diminutive size. The hood wears a mini-bulge in the center, simultaneously suggestive of a scoop and of a similar bulge on the RX-8.
The MX-5 design has definitely evolved since the beginning, especially when seen from the side. Sharply sculpted wheel flares appear directly adapted from the RX-8 in a form the company calls Mazda design DNA. Flared wheel arches also spread wide enough to cover the new-generation Miata's wider track. (Track is the distance between the left and right wheels). The MX-5's track is three inches wider in front, two inches wider in the rear when compared with the previous model. This gives the MX-5 a more athletic stance. The MX-5 looks more aggressive and less cuddly than its predecessors.
The soft top is the best yet, and one of the best in all sportscardom. The top, with its heated glass rear window, collapses into a well behind the seats cleanly and completely, in a way requiring no cover boot. That's good, because there are plenty of times when you'd like to drop the top but don't want to take time to snap on a cover. Now it looks neatly finished when it's down, with no additional effort. As with previous models, it's manually operated, but so light and easy to use you can do it with one hand while sitting in the driver's seat. You'll never wish for power assistance. This is distinctly different from, say, the Pontiac Solstice and Saturn Sky, whose tops are far more involved to raise and lower.
The folding hardtop is a mastery of good design. The PRHT is a cinch to operate, quick to fold, and a miracle of space efficiency. Stop the car, put it in neutral (or Park for the automatic). Pop a single handle at the top of the windshield, touch a button on the dash and in 12 seconds the top has contorted itself into the same well the soft-top uses. The hardtop is made of lightweight materials: sheet molding compound on the outside and glass fiber-reinforced polypropylene on the inside. The entire apparatus including electric motors adds less than 80 pounds to the featherweight car, thus maintaining the MX-5's wonderful agility and balance.
A rear panel aft of the front seats raises as part of this dance to allow the top to drop into the well, and covers it back up once it's snuggled in place. Trunk room is not impacted in any way, a blessing because the MX-5 has so little of it to begin with. (Note that even some of the luxury-class folding-hardtop sportscars suffer here, because their tops actually fold down into the trunk and eat up as much as half the available cargo space. Not so for the MX-5.) A slight ridge sculpted into the PRHT's top cover is the only noticeable difference between the hardtop and soft top cars' appearance when the tops are down.
With the top down, you'll notice rollbar-like hoops rising out of the body behind the seats; Mazda doesn't list them as safety features, calling them seat back bars, but they're certainly more than merely surfaces to which decorative trim can be affixed. A mesh windblocker fits between the hoops. Small quarter windows, like yesteryear's windwings, fill the acute angle where the doors meet the A-pillars. Door handles are finger-friendly full rounds, instead of the previous model's top-hinged pull-ups. The hardtop boasts a larger rear window than the soft top offers, substantially reducing the convertible's rear quarter blind spots.
Taillights retain the basic elliptical outline of Miatas past but, like the headlights, nestle a little closer toward the car's middle. Even the rear license plate housing's contours are round and crisply molded into the surrounding sheet metal. A horizontal, black panel beneath the rear bumper echoes the front end's air dam, only this one is braced by twin exhaust tips, adding a look of purposefulness to the tail end.
For 2007, there are two new paint colors in the palate: Stormy Blue Mica and Highland Green Mica and some additional bright work added to the nose of the car.
