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.

74 2.3 runs rough small backfires

my 78's 2.3 does this too, small backfires/misfires. I always assumed it to be rich mixture and just an issue with my carb. Guess I should play with timing it a bit, again.

Thing is, I have timed it over and over, PERFECTLY timing it with the correct professional tools that my cousin uses to time the motors in the drag cars he builds. Nothing seems to fix it. As far as me and him are aware, the head has never been shaved, even when the motor was rebuilt. Could be they shaved it and didn't add the charge to the receipt though, since he used his company name to have the work done under, in order to give me a discount on the work.

On another note, I have noticed that it smooths out A LOT once the motor is at normal operating temperature. It smooths out a little more once I adjust the distributor timing as well, but then it idles to high and i adjust the curb idle to compensate, then the random misfiring/backfiring comes back.

Smog cams are already retarded at LEAST 4* from the factory back in the old days.... their high tech solution to more stringent smog laws. That said, if you are already 4* retarded, ANY amount shaved retards it even more.

The guy at the tire shop I use has an adjustable cam gear he said he'd sell me for $30. I probably should pick that up. He used to race pintos and 2.3s on dirt tracks.

sounds more like a 'misfire' than a 'backfire'

The day I started troubleshooting this problem the exhaust  had broken off a couple feet behind the engine. The exhaust is fixed now and you cant really hear them anymore, but there were obvious small backfires happening every couple seconds. There wasn't any pattern to it, it wasn't consistently happening every "X" number of seconds, it was just random.

The distributor could be off by a tooth too,,, stick a wad off butt wipe in the number one cylinder turn it over by hand and when the butt wipe blows out with a pop stop,,, then put a long small clean stick in the # one plug hole turn the engine back and forward a little  by hand and find top dead center of the piston,,,then take off the distributor cap and see if the rotor points to number one wire on the cap if it dont then pull the distributor out a little and turn the rotor till it lines up with number one and replace  it   Hint: put a chalk mark on the base of the distributor lined up with number one on the cap this will make it easy to line the rotor with...               P.S  If you find top dead center and pull the  distributor cap and it`s lined up with number one,,, then thats not the problem>>>> :read:  Before you change the wires start it in the dark and watch for sparking lift the wires too and look

Yes it was shaved .005"

I installed a new set of plug wires last night and it made no difference. The new MSD blaster 2 coil i installed did tho ;) Still not fixed totally but it helped.

Consider buying a Motorsports multi-index crank sprocket or (as I did) a Racer Walsh adjustable cam sprocket. You mentioned you had a valve job done, and if it was surfaced (likely) your cam timing is retarded. I wound up advancing my cam 4 1/2* and am considering another 1/2*. 

pintoguy76

that drive gear has been an issue in the past for me but each time the pin in it broke, it would not run at all.  I could reposition the distributor but that would be a bandaide fix. It should run decent with the rotor pointed to #1 tower. I must have something wrong somewhere is all i can think. If the points or dwell was off would it cause this?

I installed the MSD Blaster 2 coil tonite and it dramatically improved the shake but its still there some. The backfiring you cant hear much if at all. New plug wires are going on it tomorrow. Will report back my findings. May be time to try the matchbook trick rather than a feeler gauge.

I was going to say the same thing, to recheck the timing belt around the auxiliary shaft sprocket. Since you've done that already....

Have you check the drive-gear on the distributor? I've heard, lately, about that causing problems for some members.

With my 78's 2.3, I have removed the distributor, then dropped it back into the motor at a different angle, one that would allow the same advance/retard adjustments, but with more room to adjust. This is all done without removing the timing belt.

I've timed that thing 15 times if i've timed it once.  The other two pintos ive got (also 2.3s) dont have these problems and i've put timing belts on them as well so I dont think thats the problem. I think i may be misleading when i say it backfires. It only does it a little bit every few seconds when the engine is not under load and while holding the engine at high rpm (2 or 3k rpm). This is when it shakes and makes backfires. Even then its just every few seconds and sometimes it pops worse than others. It runs too good for the belt to be off much if at all. This is a daily driven car, it idles good and drives fine but I know something isnt right. I've never thought its had the power that it should have, its a 74 2.3 4 SPD 3.55. Theoretically it should be lighter and have more power than my other two pintos (76 2.3 3.00 4 SPD and 79 2.3 3.08 C3) but oddly enough my 79 with the C3 has the most power.

Anyone know about the MSD?

Sounds like your cam belt may be incorrect.  Set your crankshaft to top dead center (0*), pop the rubber frapits off of the belt cover and check to see if the "bump" on the cam is correctly aligned with the center of the three marks on the rear cam cover.

If not, redo the belt as shown (sort of - later model 2.3) here: http://turbotbird.com/techinfo/CamTiming/Cam%20Timing%20Belt%20Replacement%20and%20Set%20Up.htm

Do check this first.  If your car has manual brakes, check the vacuum 'tree' at the rear of the intake manifold.  The big capped vac hose connection on mine often springs a leak and does what yours does.  The rubber caps deteriorate quickly. 
Other vac lines can crack and break at this age. 

You should have a choke - what is wrong with it?  I think it should be water temp sensing. 

I assume spark plugs look okay...

Funny you mention disty caps - mine has the original cap at over 153K miles!

Plugs are fine. Choke is not installed. I have the pulloff installed just so it has the seal  to seal up the vacuum hole.  There is no butteryfly for the choke installed and the linkage isnt hooked up to the choke pull off.

Car does have manual brakes and I have noticed that the vac caps dont last too long. However this problem has occured with this car since ive had it (got it in 2006) and ive had numerous caps on it.

I think it IS time to remove  the vacuum fittings in the intake and install pipe plugs tho.

Just for the record, My 79 has the original spark plug wires on it. Dont know about the cap and rotor but they could be  original too.  Only 100k on it tho.

Usually when my 78 (duraspark, no points) does this, I replace the plugs cap and rotor, then double check the fuel/air mixture and timing. Seems to work fine. I usually end up spending about $30 on all the parts.

The vacuum leak is most possibly the cause, though.

My 78 had the same symptoms and it took me two weeks to figure out that it was the cracked EGR valve. I removed the valve, fabricated a block-off plate, took off the EGR tube and bought a plug for the exhaust manifold connection. Never really had any problems since.

I have an EGR plate that I built that I need to put on it.

I need to also mention that I cant seem to set the timing right. When I time the engine, i set the dist at the #1 tower on the cap. The engine wont start or starts very hard at that setting. I end up having to push the distributor all the way up against the block to get it to run and run right. Cant set it by the light either. Wont run right when its set to spec.

Also, I have an MSD blaster 2 coil. Will that work with the points? That puppy will throw some voltage to the plugs!

Having trouble with my 74, had trouble with it since ive had it. Have to rev it and hold it for several minutes until it warms up enough to idle on its own. Thats no problem,  i expect  that since there is no choke. However the engine (and thus the whole car) shakes like crazy while this is happening. There are small backfires ocassionally while this is happening. Under load (while driving) it runs fine. But sitting still in neutral or with the clutch pushed in  and reving the engine it shakes like crazy and like i said it has little backfires.

The head was rebuilt in late 2006 and it doesnt have many miles on it since then. Compression is 120 across the board. Carb does have  a vacuum leak around the primary throttle shaft but i have attempted to correct that with a steel washer with a rubber backing on it on the throttle shaft against the carb base in an attempt to seal it. I dont know if that would cause the problem i am having or not, I dont think so tho. I have a smaller vac leak on my 76 in the same spot and it doesnt act up like this. Any ideas whats wrong? Could it be tiiming related? It has points and im not sure how accurate ive ever had it.
