Yes, you are right about the front and the Shelby. But somehow nobody seems to care about that. It's just a styling detail.

What I was getting to is that they're always being compared to the previous models and except the front styling resembling that of the 70 Shelby they have come a far way from the "original" idea.

By the way the 70 Shelby look is very different from the normal 70 Mustang.

By the way I think too that the 69 Mustang fastback is the coolest and best design in Mustang history.

 
I get what you're saying, but that's just natural progression of the evolution of cars in general... so I say, "waah, get over it Classic Mustang purists." Not to mention, the whole 'deviation' really began with the '69s anyway - but I guess because everybody likes the '69s so much, they're willing to overlook that little detail.

You know, if the Classic Mustang purists think the '71 went too far astray of what the original Mustang was all about, imagine how the Camaro/Firebird purists must've felt when the '70 Camaro/Firebirds came out.

 
Then why are you not a big late-model Corvette guy? Them's some big-assed hoopties! rofl

Because he likes it when the frame of his car doesn't disintegrate after 15 years. Besides, who wants to drive in a "birdcage" anyway?

You guys have it all wrong. These Mustangs were much larger when new, but over time, they seem to shrink. How do I know? I can't fit into the seats anymore and have room between the steering wheel and my legs. They are just shrinking with time, that's all.

The same damn thing happens with airplane seats and seat belts, too! It's a conspiracy, I tell ya.

Yeah, no kidding. It must be going around... like the flu... except less temporary. I remember when I used to fit comfortably in a Fox body with no complaints. Guh...

 
this is an old threads that I missed out on but I find the topic interesting because the Mach 1 version of our cars is such a unique design that came and went at the tail end of the glorious era of American muscle never to be seen again.
Ok detractors use phrases like ballooned and piled on yet we know the dimensional changes from 1970 are
3.6 inches wider
2 inches longer
1 inch lower
1 inch increase in wheel base
Yet recently my car was in the shop and next to it was a 1970 Mach 1.
I was amazed how much bigger my car appeared. It is an optical illusion! the length of the hood the lowness and the width combined with the way it flares at the front wheels then tapers to the rear yet
Mysteriously The roof and the deck lid are one . I was amazed how much smaller the seventy seemed. If I did not know the actual dimensional difference I would assume they were greater.
The width is significant. We all know why. the 429 engine the car was designed to accept. A good trade off in my opinion but opinions very.
 
I fully believe that the '71-73 Mustang size discussion originates back to Lee Iaccoca. In 2004, he stated this to Mustang Monthly:

"Well, Mustang got into the world of politics. When Bunkie Knudsen came in from GM during 1968, he and Larry Shinoda took the thing. At the stockholder meetings I'd have to listen to, 'Why do you take a winning formula like the Mustang, call it Boss, put a 429ci mill, have to spread it, [and] make it wider and lower? How could you be so dumb?' We got sucked in. Not me. This was Knudsen doing it. I think he wrecked the Mustang." Lee went on to say, "It got heavy. I thought, 'Whatever happened to my 2,200-pound Mustang?' They changed the whole feel and character. We wanted to keep it nimble and small."

Sound familiar? I have a feeling Lee quietly sounded off these statements long before this interview and became more and more vocal once the Bunkster was booted in 1970. That means that by the time the car went to launch, Lee could have been even looser with his tongue to spite Bunkie, at the risk of the car's success. Never underestimate someone to put their personal goals first over company interests when it involves creative decisions.

I would put a few dollars down that this is exactly what happened and journalists jumped on the fresh gossip back in the day. Remember, Iaccoca was a brilliant marketer. Any brilliant marketer also knows how to smear their foes using the oxygen of publicity.

50 years later, these comments continue to get regurgitated by current-day classic car journalists working to meet their copy deadlines rather than take the effort to dig up the owner of a stock or mildly modified '71-73 to sit in and drive. When was the last time you've heard someone new to the '71-73 provide a fresh insight or opinion in a mainstream article? That's right, never. If it's simple magazine or internet influencer fluff, "who cares, right?" In the words of Harrison Ford: "...I got paid!"

At any rate, I'm not convinced the size or weight alone put people off on the car back in the day (hey, weight didn't stop the LX-platform Chargers, it isn't exactly stopping the new 5-series either, nor is it stopping Model 3 Performance sales), but it was these factors combined with the Mustang's first truly radical change in styling. It went from an all-American coke bottle to - for the Sportsroof - a shape heavily influenced by Italian GT styling cues. By comparison, a '69 Sportsroof retains enough DNA from its predecessors that it comes off as a refinement of the original first-gen, not a departure. Let's not forget Gale Halderman admitted that Bertone studio designs served as inspiration for the '71-73s.

Combine this with the "European-styling" ad campaign for the '71 with Sid Cesar Doing Characters That Would Get You Cancelled Today and you have a product that's saying "I'm not for you" to the person who wanted a '69 428 Cobra Jet a few years prior. Think of it similar to what the Mach-E's launch was saying to owners or potential owners of S550s - the same exact thing, "I'm not for you."

The '71-73 was the Mustang's first departure from the norm and it bore the brunt of the hit - first from Iaccoca's personal vendetta filtered to journalists, and the journalist's comments distributed amongst the peanut gallery of commentators and onlookers forming their opinions without ever sitting in or driving one of these cars.

Ironically, as it was the first Mustang to bear the brunt of being radically different, I believe it softened the blow for the Mustang II, arguably the Mach-E of 1974: A car that sold primarily on practicality for the masses with just enough of nostalgia glitter spread over the turd to encourage someone to buy it over a more boring label. Yet, journalists continue to praise the little chitty chitty chit box to this day for being the "right car at the right time." Sorry, auto journalists, but if you're reviewing the same model of car, you can't play both the practical card and the emotional card if the car changes identity 10 years down the road. Pick a lane and stick with it.

At any rate, the legacy of pissing on the '71-73s continues because it is easy to spew nonsense from an armchair (or a desk) without any first-hand experience. It is also easy for others who have even less experience to assume that person knows what they're talking about, which is why all the "big Mustang" comments continue through into an era where everything weighs as much as an old ladder-frame truck, package sizes and SUVs have influenced sedans into having rooflines higher than our heads, and trucks are now the size of small buildings in a self-defeating automotive arms race that needs to effing stop before road rage turns into out into an all-out war.

Incidentally, the same thing is going on right now with automotive journalists and social media mouthpieces consistently claiming the new J250 Land Cruiser is "smaller" than it's predecessor. Hardly - by exterior dimensions, it's the same or fractionally larger; the interior is smaller. Only Jason Cammisa has made this distinction and he's admonished all of his peers for screwing it up (as he often does). Nevertheless, watch as time allows the more prevalent (read = copy pasted and paraphrased and/or AI generated) "smaller" narrative to erroneously sear itself into the legacy of the J250 Prado-based LC here in the States, 20 years in the future.

Wow! a lot of good historical and factual documented references here. I am fascinated with the design of these cars but I feel my perspective is incomplete because I have never driven an older Mustang than 71. So how can I judge the validity of naysayers in terms of handling and driving feel? I cannot.
I used to think 71-73 mustangs were ugly. Now I think in terms of exterior design they are fascinating (at least in my mind) along with all the ford products of that era. I think it is a funny thing
Because I recognize the older mustangs as being more classic more timeless but yet I prefer 71-73 sport roofs to anything. They are a hybrid / pony / muscle car. Which to me equals biggest engine in smallest package.
There is no other car that has that dynamic profile. It give the appearance that the nose is higher than the tail even when shod with staggered tires that tilt the car higher in the rear. The design cues of the SR71 aircraft are carried out in the proportions and lines and shape of the car to such a degree it gives it an eccentricity that separates it from other automobiles including previous mustangs. It is a fundamentally different shape. It IS weird and funky And cool and sexy and powerful looking at the same time and you are either able to appreciate it as such or you are not. To me it makes it more interesting but it took me a while to develop that appreciation. The European road car influence is something I did not register probably because I don’t know a lot about European cars of that era. I have seen the Sid Ceasar commercial. I wonder what would be a prime example from Italy that would be similar?
Lee Iacocca clearly did not embrace the 71-73 cars and some of that could have been fueled by his professional rivalry with Knudsen however if he felt nimbleness Is the main priority of the mustang then he had a point, but like I stated I have not drive an older mustang so I can’t gauge to what degree the nimbleness of the older cars was sacrificed. With cars however I have noticed how a few inches can be significant in terms of feel. Subtle changes in Mass/ weight and overall footprint do as well. I can see how that could be a deal breaker for some folks , particularly if the live in hilly areas with tight curvy roads.
When I pop the hood and see that huge chunk of American Ford v8 429 goodness I feel ok about the trade off.
I have never driven a Cleveland powered car but I like the architecture of the engine. It is unique how it has big block proportions as far as the deck hight. I bet those motors love to rev.

As Kurt said, the 71-73s were badmouthed to no end, and still are by unoriginal, unimaginative people with no real skin in the game to make that call. Crazy how long it takes to shake off a bad reputation.
I've driven the smaller Mustangs and I can tell you, they do feel a bit lighter on their feet, although not the night and day difference it's made out to be. The real difference becomes apparent when you sit inside. The older Mustangs had a low beltline and a relatively gigantic greenhouse. It feels like you're in a small car. The 71-73 has a very high beltline, small windows, and curves that make it harder to see the corners of the car. It's mostly an optical difference. I've thrown both around corners in an indecent manner, and ultimately, I feel the 71-73 have more overall potential for handling. The wider track, lower center of gravity and superior aerodynamics are a better platform to start from than the previous models. The little bit of extra weight is easily compensated for. Look at the monstrously heavy S650s and how well they perform despite being 4000lbs.
Our cars are the most well executed, most polished form of the first generation, and I will die on that hill. Maybe not the prettiest, but the best overall.
The guys in VMF would be throwing tomatoes at me right now.

That is a terrific explanation thanks for the first hand feedback.
