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."

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.

Actually everybody is right.

Too rich, just right, AND too lean of a combustion mixture can all produce produce enough heat in the exhaust system to make one or more parts of it get hot enough that it/they may actually glow, depending upon the conditions.

If any engine is run fast enough and/or long enough without adequate lubrication, or has insufficient cooling, the heat that is being produced by the engine as a WASTE product of combustion in our beloved internal combustion engines, will eventually build up past that engines' designed-in ability to cool itself, and localized sections of the engine will get MUCH hotter than they are able to efficiently transfer the now accumulating heat to the surrounding air.

If an engine that was NOT factory designed for them is now sporting thin steel tubing headers, and is run for long at higher engines speeds, the thin cross sectional area of their runners is MUCH more liable to locally accumulate more heat than it can hold without being able to transfer it to anywhere other than the air, as the total BTU's of heat in a locallized area cannot move through the smaller amount of metal of the header at that particular point.

Anyone who has replaced heavy cast iron exhaust manifolds with thin tubing headers will immediately notice the vast weight difference, especially noticible in the front section of the steel vs the cast iron. The point can also be illustrated by someone attempting to heat up or cut iron or steel with a torch. The thicker the crossectional area or greater the mass involved, the more BTUs must be applied to raise and hold the temperature of the piece, and more importantly for this point, the more rapidly the metal will drop from being hot enough locally to glow, once the source of heat is removed or reduced. The BTU's are still IN the piece, but they migrate much more rapidly in the thicker piece to equalize it's temperature   


So,
As the temperature of the exhaust is the hottest at, and immediately after leaving the combustin chamber, the closer to that point, the more any increased amount of heat will be liable to have enough additional BTUs to heat metal to it's glowing point. INSIDE the engine, the heat is dealt with MUCH more efficiently, as heat exposed to water or to coolant has a much faster RATE of transfer than does heat to air. I used to know the exact comparative rates, but it's somewhere in the neighborhood of water being 20X as effective in heat transfer as is air. That's one of the primary reasons why most internal combustion engines that produce high levels of power are "water" cooled rather than being air cooled, the safety factor against an engine overheating is so much higher with this design, that it outweighs the weight penalty associated with the wet cooling system. Parts can also be designed and machined to tighter tolerances when their operating temperature remains within a narrower range, thus increasing overall engine efficiency.   


Anyway,

Assuming for the moment that the fuel air ratio coming through the carb itself has not changed significantly:
Much of the time when an exhaust system does get that hot, it has more to do with either a NEW restriction or blockage in the exhaust (seriously dented pipes/slipped gaskets/muffler baffles having broken off and now blocking the muffler outflow part way, etc.), that is making the hot gases take longer than whatever would be "normal" (for that particular engine), to move out of the very beginning of the exhaust system, where the exhaust is typically hottest, into the rest of the system, where it continues to give up heat all along the exit path;

or

timing issues, (as has already been mentioned);

or

additional sources of combustible fuel or supplied air having been changed so that the OVERALL fuel air ratio within the cylinder has now changed. (EGR valve problems, for example, recently changed oil seals, more efficient ignition resulting in a more consistent spark (fewer misses), etc., etc., etc.)

or
something that relates more to emission controlled engines more than to earlier ones, and that is the continuing combustion process that takes place OUTSIDE of the combustion chamber in those engines more than in previous designs.

Any engine equipped with a catylitic convertor has the added possibility of the cat slowly accumulating enough deposits that it begins to restrict the exhaust flow, even if nothing else engine related has changed.

Sometimes (if the engine has one)
the beginning of a clogged cat can be traced to a malfunctioning 02 sensor, which triggers the engine to run richer if it has a computer controlled fuel system, for example. Other times, if the engine has been modified and it's air pump removed, for example, so that it's EXHAUST outside of the combustion chamber is now consistently running richer than it's designed in parameters and the cat retained, the cat will definitely be more prone to early failure from clogging. This may take quite a long time, especially if the engine has a one-size-fits-all cat, which may have a lot of excess air flow capacity.

After checking allthe "normal" possibilities for problems that are heat related,
I'd suggest disconnecting the exhaust system one additional piece at a time, starting with the muffler and working forwards,if no large dents are visible, and see if the exhaust no longer gets as hot. If there is a big difference when removing one particular piece, that's a likely source of the problem.  They used to market a "test" pipe that was used to help diagnose a clogged convertor. Many people assume that this was ONLY a scam to get around the inspectors and improve performance. tain't so.

GENERALLY speaking. when the exhaust is glowing red, it is rich not lean. 

Wrong, lean = heat and melted parts.

The headers will also glow at the primary tubes on a properly tuned engine if you run it fast enough for a long enough time.

GENERALLY speaking. when the exhaust is glowing red, it is rich not lean.  Or the ignition timing is retarded.

p84

Did you change anything on the carb. You can be running into a very lean fuel situtation causing the header to become extremely hot. It also could be ignition timing allowing the exhaust valve to open to soon causing it to expell heat, or a combination of both. Did you ever look at the cat when your headers were glowing red. If the cat backs up it usually will turn bright red and cut power to the motor causing it to backfire and miss. If it was my guess, I would go with the lean situation. Your changing the cylynder temperature thats why your water temp is staying at 195. I blew up race motors this way. " Lean is Mean "

i don't know much about it.  i have heard of headers glowing red beford.  You could always get a high flow cat,  or since the emissions law wasn't passed,  take it off and save it.  because my pinto is in such good condition, i kept the original muffler when i put on a high flow. 
     Also,  on my 80 bobcat, i took off the cat, and it would backfire and shoot flames.  but i messed with some hoses and it stopped.  i too stripped the engine of anything not needed.

I've got a 79 pinto that I have done a variety of basic modifications to the engine. Mainly removing air pump and extra hoses. I had to reinstall a catalytic converter when we were threatened with mandatory emission testing quite a few years ago. (The emission testing never was passed into law) now I notice the header I put on this engine is running very hot, actually glowing red the last time I checked. Needless to say I need to do something before I can run it again. The engine itself is running OK about 195 degrees. Could the catalytic converter be causing enough backup to cause the extreme heat? Or should I be looking at something else to cool this thing down?
