Why the Ford Pinto didn’t suck

Why the Ford Pinto didn't suckThe Ford Pinto was born a low-rent, stumpy thing in Dearborn 40 years ago and grew to become one of the most infamous cars in history. The thing is that it didn't actually suck. Really.

Even after four decades, what's the first thing that comes to mind when most people think of the Ford Pinto? Ka-BLAM! The truth is the Pinto was more than that — and this is the story of how the exploding Pinto became a pre-apocalyptic narrative, how the myth was exposed, and why you should race one.

The Pinto was CEO Lee Iacocca's baby, a homegrown answer to the threat of compact-sized economy cars from Japan and Germany, the sales of which had grown significantly throughout the 1960s. Iacocca demanded the Pinto cost under $2,000, and weigh under 2,000 pounds. It was an all-hands-on-deck project, and Ford got it done in 25 months from concept to production.

Building its own small car meant Ford's buyers wouldn't have to hew to the Japanese government's size-tamping regulations; Ford would have the freedom to choose its own exterior dimensions and engine sizes based on market needs (as did Chevy with the Vega and AMC with the Gremlin). And people cold dug it.

When it was unveiled in late 1970 (ominously on September 11), US buyers noted the Pinto's pleasant shape — bringing to mind a certain tailless amphibian — and interior layout hinting at a hipster's sunken living room. Some call it one of the ugliest cars ever made, but like fans of Mischa Barton, Pinto lovers care not what others think. With its strong Kent OHV four (a distant cousin of the Lotus TwinCam), the Pinto could at least keep up with its peers, despite its drum brakes and as long as one looked past its Russian-roulette build quality.

But what of the elephant in the Pinto's room? Yes, the whole blowing-up-on-rear-end-impact thing. It all started a little more than a year after the Pinto's arrival.

 

Grimshaw v. Ford Motor Company

On May 28, 1972, Mrs. Lilly Gray and 13-year-old passenger Richard Grimshaw, set out from Anaheim, California toward Barstow in Gray's six-month-old Ford Pinto. Gray had been having trouble with the car since new, returning it to the dealer several times for stalling. After stopping in San Bernardino for gasoline, Gray got back on I-15 and accelerated to around 65 mph. Approaching traffic congestion, she moved from the left lane to the middle lane, where the car suddenly stalled and came to a stop. A 1962 Ford Galaxie, the driver unable to stop or swerve in time, rear-ended the Pinto. The Pinto's gas tank was driven forward, and punctured on the bolts of the differential housing.

As the rear wheel well sections separated from the floor pan, a full tank of fuel sprayed straight into the passenger compartment, which was engulfed in flames. Gray later died from congestive heart failure, a direct result of being nearly incinerated, while Grimshaw was burned severely and left permanently disfigured. Grimshaw and the Gray family sued Ford Motor Company (among others), and after a six-month jury trial, verdicts were returned against Ford Motor Company. Ford did not contest amount of compensatory damages awarded to Grimshaw and the Gray family, and a jury awarded the plaintiffs $125 million, which the judge in the case subsequently reduced to the low seven figures. Other crashes and other lawsuits followed.

Mother Jones and Pinto Madness

In 1977, Mark Dowie, business manager of Mother Jones magazine published an article on the Pinto's "exploding gas tanks." It's the same article in which we first heard the chilling phrase, "How much does Ford think your life is worth?" Dowie had spent days sorting through filing cabinets at the Department of Transportation, examining paperwork Ford had produced as part of a lobbying effort to defeat a federal rear-end collision standard. That's where Dowie uncovered an innocuous-looking memo entitled "Fatalities Associated with Crash-Induced Fuel Leakage and Fires."

The Car Talk blog describes why the memo proved so damning.

In it, Ford's director of auto safety estimated that equipping the Pinto with [an] $11 part would prevent 180 burn deaths, 180 serious burn injuries and 2,100 burned cars, for a total cost of $137 million. Paying out $200,000 per death, $67,000 per injury and $700 per vehicle would cost only $49.15 million.

The government would, in 1978, demand Ford recall the million or so Pintos on the road to deal with the potential for gas-tank punctures. That "smoking gun" memo would become a symbol for corporate callousness and indifference to human life, haunting Ford (and other automakers) for decades. But despite the memo's cold calculations, was Ford characterized fairly as the Kevorkian of automakers?

Perhaps not. In 1991, A Rutgers Law Journal report [PDF] showed the total number of Pinto fires, out of 2 million cars and 10 years of production, stalled at 27. It was no more than any other vehicle, averaged out, and certainly not the thousand or more suggested by Mother Jones.

Why the Ford Pinto didn't suck

The big rebuttal, and vindication?

But what of the so-called "smoking gun" memo Dowie had unearthed? Surely Ford, and Lee Iacocca himself, were part of a ruthless establishment who didn't care if its customers lived or died, right? Well, not really. Remember that the memo was a lobbying document whose audience was intended to be the NHTSA. The memo didn't refer to Pintos, or even Ford products, specifically, but American cars in general. It also considered rollovers not rear-end collisions. And that chilling assignment of value to a human life? Indeed, it was federal regulators who often considered that startling concept in their own deliberations. The value figure used in Ford's memo was the same one regulators had themselves set forth.

In fact, measured by occupant fatalities per million cars in use during 1975 and 1976, the Pinto's safety record compared favorably to other subcompacts like the AMC Gremlin, Chevy Vega, Toyota Corolla and VW Beetle.

And what of Mother Jones' Dowie? As the Car Talk blog points out, Dowie now calls the Pinto, "a fabulous vehicle that got great gas mileage," if not for that one flaw: The legendary "$11 part."

Why the Ford Pinto didn't suck

Pinto Racing Doesn't Suck

Back in 1974, Car and Driver magazine created a Pinto for racing, an exercise to prove brains and common sense were more important than an unlimited budget and superstar power. As Patrick Bedard wrote in the March, 1975 issue of Car and Driver, "It's a great car to drive, this Pinto," referring to the racer the magazine prepared for the Goodrich Radial Challenge, an IMSA-sanctioned road racing series for small sedans.

Why'd they pick a Pinto over, say, a BMW 2002 or AMC Gremlin? Current owner of the prepped Pinto, Fox Motorsports says it was a matter of comparing the car's frontal area, weight, piston displacement, handling, wheel width, and horsepower to other cars of the day that would meet the entry criteria. (Racers like Jerry Walsh had by then already been fielding Pintos in IMSA's "Baby Grand" class.)

Bedard, along with Ron Nash and company procured a 30,000-mile 1972 Pinto two-door to transform. In addition to safety, chassis and differential mods, the team traded a 200-pound IMSA weight penalty for the power gain of Ford's 2.3-liter engine, which Bedard said "tipped the scales" in the Pinto's favor. But according to Bedard, it sounds like the real advantage was in the turns, thanks to some add-ons from Mssrs. Koni and Bilstein.

"The Pinto's advantage was cornering ability," Bedard wrote. "I don't think there was another car in the B. F. Goodrich series that was quicker through the turns on a dry track. The steering is light and quick, and the suspension is direct and predictable in a way that street cars never can be. It never darts over bumps, the axle is perfectly controlled and the suspension doesn't bottom."

My Somewhat Begrudging Apology To Ford Pinto

ford-pinto.jpg

I never thought I’d offer an apology to the Ford Pinto, but I guess I owe it one.

I had a Pinto in the 1970s. Actually, my wife bought it a few months before we got married. The car became sort of a wedding dowry. So did the remaining 80% of the outstanding auto loan.

During a relatively brief ownership, the Pinto’s repair costs exceeded the original price of the car. It wasn’t a question of if it would fail, but when. And where. Sometimes, it simply wouldn’t start in the driveway. Other times, it would conk out at a busy intersection.

It ranks as the worst car I ever had. That was back when some auto makers made quality something like Job 100, certainly not Job 1.

Despite my bad Pinto experience, I suppose an apology is in order because of a recent blog I wrote. It centered on Toyota’s sudden-acceleration problems. But in discussing those, I invoked the memory of exploding Pintos, perpetuating an inaccuracy.

The widespread allegation was that, due to a design flaw, Pinto fuel tanks could readily blow up in rear-end collisions, setting the car and its occupants afire.

People started calling the Pinto “the barbecue that seats four.” And the lawsuits spread like wild fire.

Responding to my blog, a Ford (“I would very much prefer to keep my name out of print”) manager contacted me to set the record straight.

He says exploding Pintos were a myth that an investigation debunked nearly 20 years ago. He cites Gary Schwartz’ 1991 Rutgers Law Review paper that cut through the wild claims and examined what really happened.

Schwartz methodically determined the actual number of Pinto rear-end explosion deaths was not in the thousands, as commonly thought, but 27.

In 1975-76, the Pinto averaged 310 fatalities a year. But the similar-size Toyota Corolla averaged 313, the VW Beetle 374 and the Datsun 1200/210 came in at 405.

Yes, there were cases such as a Pinto exploding while parked on the shoulder of the road and hit from behind by a speeding pickup truck. But fiery rear-end collisions comprised only 0.6% of all fatalities back then, and the Pinto had a lower death rate in that category than the average compact or subcompact, Schwartz said after crunching the numbers. Nor was there anything about the Pinto’s rear-end design that made it particularly unsafe.

Not content to portray the Pinto as an incendiary device, ABC’s 20/20 decided to really heat things up in a 1978 broadcast containing “startling new developments.” ABC breathlessly reported that, not just Pintos, but fullsize Fords could blow up if hit from behind.

20/20 thereupon aired a video, shot by UCLA researchers, showing a Ford sedan getting rear-ended and bursting into flames. A couple of problems with that video:

One, it was shot 10 years earlier.

Two, the UCLA researchers had openly said in a published report that they intentionally rigged the vehicle with an explosive.

That’s because the test was to determine how a crash fire affected the car’s interior, not to show how easily Fords became fire balls. They said they had to use an accelerant because crash blazes on their own are so rare. They had tried to induce a vehicle fire in a crash without using an igniter, but failed.

ABC failed to mention any of that when correspondent Sylvia Chase reported on “Ford’s secret rear-end crash tests.”

We could forgive ABC for that botched reporting job. After all, it was 32 years ago. But a few weeks ago, ABC, in another one of its rigged auto exposes, showed video of a Toyota apparently accelerating on its own.

Turns out, the “runaway” vehicle had help from an associate professor. He built a gizmo with an on-off switch to provide acceleration on demand. Well, at least ABC didn’t show the Toyota slamming into a wall and bursting into flames.

In my blog, I also mentioned that Ford’s woes got worse in the 1970s with the supposed uncovering of an internal memo by a Ford attorney who allegedly calculated it would cost less to pay off wrongful-death suits than to redesign the Pinto.

It became known as the “Ford Pinto memo,” a smoking gun. But Schwartz looked into that, too. He reported the memo did not pertain to Pintos or any Ford products. Instead, it had to do with American vehicles in general.

It dealt with rollovers, not rear-end crashes. It did not address tort liability at all, let alone advocate it as a cheaper alternative to a redesign. It put a value to human life because federal regulators themselves did so.

The memo was meant for regulators’ eyes only. But it was off to the races after Mother Jones magazine got a hold of a copy and reported what wasn’t the case.

The exploding-Pinto myth lives on, largely because more Americans watch 20/20 than read the Rutgers Law Review. One wonders what people will recollect in 2040 about Toyota’s sudden accelerations, which more and more look like driver error and, in some cases, driver shams.

So I guess I owe the Pinto an apology. But it’s half-hearted, because my Pinto gave me much grief, even though, as the Ford manager notes, “it was a cheap car, built long ago and lots of things have changed, almost all for the better.”

Here goes: If I said anything that offended you, Pinto, I’m sorry. And thanks for not blowing up on me.

Thank you very much. 

The adapter picced is essentially not 2 inches tall if the manifold runners are continued inside it. Recreating the same problem the shorter 1 inch one does but for more money. Funny. You can buy the 1 inch thick one, save money and hood space.

When one takes mixture, goes straight down, turns ninety degrees sideways, then ninety degrees down again and all in a relatively flat top-to-bottom package you are making far more shear than I could ever do 'blending'. I would think that is not hard to understand but I guess I'm wrong there. You apparently have never looked inside an ultra high rpm drag race tunnelram before. 

Cramped tight like that, flow to outside of all 4 holes will be blocking flow to inside and vice versa. Reversion pulses will find an easy upper 'cover' to bounce off of to rob cylinder of mixture at higher speeds, you better look at that broken piston/ring pic again. The obvious shrouding there only makes it worse. The pulsing issues there will be horrible.

When restricting the free movement of fuel/air by tightening up all airspaces there you create all sorts of oddball effects, exactly what a 2.3 stock manifold does. When you open up a plenum to a certain amount you allow the fuel/air intermixing to complete and then you don't get things like that burned piston you picced higher up. Overheating from lean and detonation jack, and most likely fuel distribution issue as well. I could point out other engines I worked on with crap adapters/manifolds like that and burned pistons in them as well, but garbage post to you.

You're focused on shear and not your issue at all.

Luck.....................

Biggest rule of porting for ANY kind of power, low or high end, regardless of how big or small ports are-------------you STRAIGHTEN things out.  If you must turn then you figure out how to do it gradually, sharp turns can NEVER be made to flow well, you are defying physics.
Had to narrow down a garbage post to this. So you'd blend a manifold and create MORE horizontal shear ? You did remember the throttle shafts on on a 38 (what my post was referring to) are parallel, right?  Don't quote theory unless you can apply it accurately.... ....

Autolite looks lower, but the big problem it the air cleaners driver side corner, as that is the first place that will hit the hood. Just making the stock air cleaner 1/4" higher WILL hit the hood. The 80's Mustang hood scoop will really look good on your wagon.
Yeah I noticed that when I measured mine it's awful close, probably need to make a custom deal to move the element towards the center?... Hmmm, never thought about that scoop they do look cool..

No way would I be putting that flow killer part on my stuff. Fuel distribution will take a dump there. You don't run around at wide open throttle all the time, start thinking about what happens when throttle blades are open 25% or less and that adapter then looks HORRIBLE. Opening up the base instead of 4 holes addresses that to a point and better and better as the carb base to top of runner increases at least to 2-3 inches. Not thinking here, when carb only open to feed off say transfers (low cruise), one side of the carb is feeding straight air, the other side of butterfly is feeding air/fuel. Main booster venture has not activated yet. You're not allowing any verticle distance for those two streams off each butterfly to fully intermingle. Two cylinders will run richer than the other two. Why many V-8s pick up power from adding a  spacer under carb, the spacer allows more turn room at top of runners but also allows better mixing up of the streams.

Can't use a 32/36 with that divider there.

Asking to make the runners longer there is a mistake, they already come far too close to carb base as it is. Why people who port the lower always end up lowering the 'X' center portion; that allows better interfeeding of all ports with each other. You cannot jam a carb base right up against individual ports without suffering pretty big power losses. Why the stock 2.3 carb manifold will not flow any more than the stock 32/36 carb even with every mod done to it you can possibly think of. 38/38 on one of those is a power detune. And thinking earlier in the thread that the D port intake was a problem? We should all have such problems, Edelbrock made millions doing the same thing with their Torker line of intakes. NONE of those match the head ports and all intentional. Some of the mismatches were quite dramatic, enough that they warned you against trying to match them back up, doing so was a massive low end power killer.

You can easily INCREASE plenum and gain low end as long as it is not out of shape size wise. There is a ratio there that all engines pretty much like, a 2 inch tall open base adapter on the EFI lower is not out of that range. I'm betting that simply using the two inch thick open base adapter will be about the same as putting on a 38/38 over a 32/36, or very close. Hood clearance is the problem there.

Look at pic on the left, you can easily see shrouding of a port by how shallow the adapter is. Big no-no there. And I don't care for the middle cross which has no gasket under it, thin enough it could crack from vibration, look at further pics on the website. It may be thin enough to crack as well if you put a 4 hole gasket under it. The squeeze may do it.

Biggest rule of porting for ANY kind of power, low or high end, regardless of how big or small ports are-------------you STRAIGHTEN things out.  If you must turn then you figure out how to do it gradually, sharp turns can NEVER be made to flow well, you are defying physics.  Anything doing otherwise costs you power. Shallow adapters that force fuel to go down then sideways and then down again are the bane of good power and a hundred manufacturers make them. They get two parts to sell instead of one for the money spent in material. One of Offenhausers' biggest flaws, they made wonky parts that defied physics to throw away big power. Much of their stuff looked cool but actually junk.

Yeah, it does lack plenum but for just a driver don't think it would hurt, air cleaner could be an issue wonder what the difference in height is between the Autolite and the Weber/Holley???..

It's p/n CS-2300 at pricemotorsport.com. I like that no alterations to the lower intake are required and it  extends the runners which should flow better. Now if I have 2" to spare.....

dick1172762

What web site was that on? Interesting to say the least. I take it was 2" tall.
Its better to be a has-been, than a never was.

Found this carb adapter for the turbo manifold that intrigues me. If I have the additional 2" of hood clearance, I might test it.

slowride

To bring this up to speed. The original engine was getting tired and I had a cylinder drop compression, so before it died I built a replacement.


WHY did it drop a cylinder? Seems a 40 year old compression ring decided it had enough......


slowride

That was a mistake. I had the Thorley on my quad cab.... what a POS. Cracked at each port at the flange as well as the collector. The Hedman WAS on the Pinto, sorry.

Sorry for the delay, but other vehicles demanded attention.
I am actually taking a step backwards and removing the header and putting the exhaust manifold back on. Without a more aggressive cam. there is no benefit to the header, and to be honest, the slip-on collector on a Thorley header leaks like a biotch and has annoyed me to no end.
The main advantage of the spacer has been a bit more power, and a smoother idle. Gas mileage has increased maybe 1 mpg, but I also suspect I need to re-jet this carb.


i thought it was a hedman header

the only substitute for cubic inches is BOOST!!!

slowride

Back from the dead! New engine, Turbo/EFI intake sitting on the bench patiently, but I want to see how much of a difference the Weber 38/38 makes over the 32/36 progressive on the stock intake. Finishing up the adapter, so it should be test and tune time in a couple weeks. Then go EFI intake...... :o


slowride

So after running the kreen in the crankcase for a few hundred miles, I've gotta say you wouldn't believe what this stuff does. I'll be doing a second treatment, but this has freed up horsepower you can FEEL. Gas mileage has gone up a bit (< 2mpg), but I'd get even better mileage if I could keep my foot out of it. It's just too much fun to jump on it even with an auto. I can actually holeshotl v8's from a stop, but after a car length or two the lack of torque takes it's toll. The real problem is, I've never driven another Pinto to get an idea if what I've done has made a marked difference from stock, or has just it made run like "new" again.

dave1987

I have noticed the "hump" in the carpet behind the e-brake handle as well. I have ACC kits in both my 78 and my 73 and have the same issue. I think it has something to do with what they use to mold the carpet with.

Not a "mod" so maybe a bit off topic, but replaced the carpet over the weekend. It makes driving a lot more enjoyable than I thought it would. Less noise, somehow a few rattles disappeared, and it has that new car smell again.  ;D
Installed an ACC carpet kit, and it fit reasonably well from the E-brake forward, but behind it on the tunnel it has an odd "hump" in the carpet that the tunnel doesn't.   :-\ Still better than what was in there, and for a daily driver I can't really complain. I rate it a 7......

slowride

Good stuff going on in the next couple weeks. Finally ordered new carpet and went original.... dark saddle 80/20 loop.
The shift kit goes in this weekend, so I should get decent shifts out of the C3.
I've also been trying something called "Kreen" made by the people that make Kroil penetrant. You add it to the crankcase to dissolve the carbon buildup from the oil control and compression ring lands on the pistons. I've been running it for 2 days and have felt a noticeable increase in power (it's a 2.3... it's not hard to feel a little more power) and the idle has smoothed out a bit. The acid test will be when I fill up and check mileage. More on that later.....

slowride

I have no doubt that due to the EFI's port layout in the plenum it will flow better and more evenly from port to port. I've already been mentally sketching out a mounting bracket for the stock throttle cable bracket assy. My limitations are that I just don't have the room to put in the equipment I need to do this kind of fabrication. This would be SO easy to do with a mill......

don33

the D port missmatch is not an issue, it has been prooven to be the best flowing stock set up for the 2.3 engine even with the missmatch..
with the skills you have shown in working on the stock piece I'm sure you could come up with something for the linkage...

slowride

Don, I may play with the EFI intake later, but this is just a $25 folly on my part. My concerns about an EFI manifold are twofold. First, the "D" port mismatch, and then the mounting issues for linkage and the stock 5200. I know I could go 4 barrel, but then that opens up another can of worms with an auto (kickdown linkage). This is my daily driver, so changes must be made in baby steps to keep it on the road day to day.
I have a "theory" floating around in my head, and this is just a quick and cheap way of proving/disproving it.

don33

slowride, while  I understand and appreciate all the work you have done to your intake, that being said, it is a very flawed and limited design. the optimum option for flow purposes would have been to put all your efforts into moding a EFI intake. they are a waaaaaaay better design. the first thing a ministock racer does is toss that chunk of aluminum you have and convert to a efi unit.

slowride

So in ANOTHER twist, I pulled the head off for a little freshening before my machine shop shuts down. Of course there was tons of carbon on the valves, chambers, etc, but looked ok. I dropped it off at the shop and called a little while later for an update. Long story short, the cam, lifters and followers needed to be replaced as well as 4 new exhaust seats. Since the cam needed to be replaced, I spec'ed out a Comp Cams 252h for a bit more lift and duration. Nothing radical by any means since going bigger wouldn't help with the header removed.
Today's the first day of my normal driving and on the way in to work it ran flawlessly. More low and mid range torque, and I got a cramp in my right ankle because I didn't have to put so much pedal into it to go the same speed. I still have the spacer on it, and the machine shop is milling the plenum on the other manifold. I am cautiously optimistic about much better gas mileage, though that may go away when I test the modified intake. Now if it's appetite  for new parts would calm down a little.....

slowride

I would like to know! I am going to pull the carb spacer/EGR plate off the next Pinto I find so I can do some of the work you have done and just swap them out when I am done. I would love to try the spacer plate as well. The more get up and go and smooth acceleration I can get from my 78, the better! Granted my 78 is a 4spd and I can change gears when I like, it's always nice to know you have a car that is using all the resources it has to drive and perform well!

The next step will be milling the dividers between ports 1/2 and 3/4 to see if the flow on the end cylinders can be evened out a bit. The change in the engine now is just with the stock intake.

slowride

Well, the seat-of-the-pants dyno is getting dialed in, and a few things are becoming evident. First. let me acknowledge one thing..... I know I'm tempting fate doing this to a car with a C3 trans. Ever since I advanced the cam, I couldn't really jump on it from a stop for fear of scattering it. I dialed in the carb and it wants to holeshot a tad better, but the smoothness of the idle is amazing (for a 2.3). Before, it would pull well in the upper rpm's, but when the secondary opened it was less than spectacular. It didn't "bog", but I had to get the rpm up to really feel when the secondary came in.  Now, it pulls a little lower and doesn't bog. Don't get me wrong, it still wants the rpm, but puts a smile on my face when I kick it down a gear, the rpm comes up, and the secondary comes in.
If anyone has some time to play around and make a spacer, I'd consider it time well spent. Granted I haven't seen the gas mileage yet (and playing with it this much may LOWER it), but it has definitely made a difference. I can't help but think it would REALLY wake up a manual trans car. If you have smaller tires than me (225/60-15 on the rear) and a manual trans, this mod should REALLY get your attention!
