The all-new 2015 Ford Mustang Convertible

Last year Chevrolet unveiled its brand-new Corvette. The Detroit icon’s gigantic V8 engine and pushrods are a Midwestern middle finger to the rest of the performance-car world. Now it’s Ford’s turn to drop a bomb on unsuspecting enthusiasts. The Blue Oval’s completely redesigned Mustang is cantering toward its fall on-sale date and a big debut on the global market.

Like the ‘Vette, this fun-loving filly is as American as Mark Twain eating a Big Mac while wrapped in old glory. Lady Liberty’s got nothin’ on the Mustang, and Ford’s all-new 2015 model promises to be the best one ever built, now with 1,768 percent less live axle!

Aero Does a Body Good

2015 Ford Mustang AerodynamicsOf course the new car features a totally restyled body. Curbing violent outbursts from faithful customers, there are still plenty of familiar Mustang design cues, things like a long hood, three-chamber tail lights and a galloping pony badge. But as the old saying goes, Satan’s in the specifics and the product development team endeavored to make the car’s body as slippery as possible.

The 2015 Mustang’s superior aerodynamics help improve fuel economy and high-speed stability. Curiously wind resistance is exponential, not linear. Apparently in engineering parlance driving twice the speed requires eight times more horsepower to overcome drag; accordingly small changes can really add up.

The new cars received about twice as much aerodynamic attention as previous Mustangs. And one of the most noticeable features is its stylish new “shark nose” front end. But this isn’t just a pretty design flourish. The sharp angle of the hood’s leading edge helps cut wind resistance.

2015 Ford Mustang Aero Skirt

Wheels and tires are a major source of drag and the design team developed a special “aero curtain” that helps reduce these parasitic losses. Vertical slots in the car’s front fascia create a path for air to flow around the side of the wheels, reducing drag.

Door-mounted side-view mirrors improve aerodynamics and help keep the cabin quiet. By moving the mirror pods away from the pillar they can keep the airflow completely detached from the side of the car, which means less resistance and noise.

2015 Ford Mustang Active Aero Shutters

Models equipped with the new 2.3-liter EcoBoost four-cylinder engine feature active grille shutters. They provide all the cooling this tiny dynamo needs and reduce wind resistance when necessary. Models with the base V6 engine as well as the V8-powered GT version make do with no fancy grilles because of their greater cooling needs.

A final coefficient-of-drag figure for the car has not been shared at this time.

DROP IT LIKE IT’S HOT… OUTSIDE AND THE SUN IS SHINING

Convertibles aren’t for everyone. They certainly appeal to individuals who love basking in all of Mother Nature’s glory but true enthusiasts tend to shy away from drop tops because typically they’re less structurally rigid and paradoxically heavier than their coupe counterparts. Still, Ford has made many improvements to the 2015 Mustang convertible.

This body style accounts for about 18 percent of the Mustang sales mix, so it’s an important model in the lineup. In fact representatives said the car is Ford’s only drop top sold anywhere in the world. If you want a Blue Oval convertible the ‘Stang is your only choice.

Like the aerodynamic team, engineers have made numerous changes to the car’s folding roof in a bid to keep inclement weather and unwanted noise at bay. Most notably, the top is powered by a pair of electromechanical motors instead of a hydraulic setup like today’s Mustang; it also features an additional top bow, which helps stretch the fabric tighter giving it a clean look.

Blocking unwanted sound, the black-only top features a three-part design. A layer of sound deadener is sandwiched between the outer cloth and the cabin’s headliner stopping NVH in its tracks.

Other upgrades include a single-point manual release compare to the two latches in the current Mustang. This makes it faster and easier to open.

On the subject of speed the 2015 model’s roof is significantly faster as well. Depending on ambient temperature and whether the engine is running or not the roof can tuck away in as little as seven seconds; that’s 50 percent faster than today’s ‘Stang.

2015 Ford Mustang Trunk Space

Thanks to a more compact design, a so-called 2-D Z-Fold layout, drivers benefit from a larger trunk that’s got enough room for two honest-to-goodness golf bags. The lift-over height has also been dropped by around two inches. Finally, the Mustang’s brand-spankin’-new independent rear suspension provides packaging advantages compared to a live axle and as a result the trunk floor is much flatter.

Aside from its hot new design and tire-smoking power Ford’s 2015 Mustang is shaping up to be a promising machine. Keep your internet browser locked on AutoGuide.com for all the latest news about this car. We’ll have much more to share in the coming months.

    1st new car was a ’65 Mustang convertible … might just as well make my last one another convertible 50 years later!

  • Bryan de Klerk

    I just don’t like the curve from the rear window to the rear of the trunk. Still on the fence on this one. I love my 2014 GT/CS but the design of the top of the trunk doesn’t fit on the 2015 to me. Don’t dig it.

    As much as I love the new fastback, I have to say this is the best looking convertible Mustang, ever, by a long shot. I have owned both 89 GT and 99 Cobra ‘verts, and while they are great when the weather is right, we live in a desert (Central California) where real convertible weather is limited to about 30-60 days a year. The rest of the time, it’s way too hot, or too cold and foggy. So, make mine a fastback. Still deciding whether they should make mine an EcoBoost or a Coyote, but one of those will work.

    I don’t know, here in Los Angeles it’s the hot summer nights that make the most of the drop tops. I love top down driving at night and 88-90f. Feels perfect. Then again I’m a convertible nutter. I’ll drive in the winter with the windows up, heat blasting, and top down. I see far too many verts with tops up in this town and I have to ask, WHY!? :)

  • Appledude

    stylewise I don’t like the 2015 front, side, or rear – however, I was thinking that perhaps things like greater gas mileage, trunk room, etc may sway me, as well as how easy the car is to get in and out of in the front. A friend has an disabled adult son, and if my 99 Mustang has one inch more clearance for him to be able to swing his foot into the car, it would help so much -

  • DMcG

    I know it! Same here. The air on a summer night is “soft.” But the sun on a 105-degree day is brutal. I used to leave the top down if at all possible, and wore a visor to keep sun out of my eyes. I guess I am older now — that doesn’t sound as appealing as it once did.

  • Scritti Politti

    What’s never discussed is the disappointing failure to cut this car’s weight, and the worsening weight distribution. The front/back distribution in the ’90s was nearly 50/50, which is even more important when the car’s a fat hog. Word is that it’s notably shifted toward the front now, which makes the increasing bloat all the more alarming.

    And the convertible top is now only available in black? Come on. Tan tops look classy and reflect the sun better, so tan should have been planned as an option from the beginning.

    It’s all great for those that are racing Mustangs that they spent so much time on aerodynamics, but most people don’t drive far enough or fast enough to really make a difference. Everyone on the road is in a big hurry anyway and doesn’t drive in a manner that saves fuel. You can take a 3.7 V-6 and 6 spd trans from a modern mustang and put it in a ’69 body and you will get about the same fuel mileage out of it.
