Post-2000 cars are MUCH more similar to 1970s cars than you think!

I'm reading the Reader's Digest book published in 1981.
That means it was written in 1980, presumably about cars of the 1970s!
I was shocked to see how current and relevant it is.
Tons of stuff that I assumed was only found in post-2000 cars are in the book

Things like:
* Fan clutch
* Cam position sensor
* Aluminum cylinder head
* Fuel Injection / Idle Control Valve / Throttle Body / Coils
* Platinum spark plugs
* Turbochargers
* Throttle position sensors

Only $4 shipped.. A great read.


  • Yup!
    All of that stuff has been around for longer than you thought.

    Does the book also mention those "wonderful" electronically-controlled carburetors of the early '80s?
    That was a truly troublesome piece of equipment.
  • Looking at it from another perspective--wasn't GM's small block 350 engine designed originally in the 1940's? Amazing that it is still around in nearly the same form.
  • Most of the things on cars have been around for many decades, but not necessarily in the form they are today. Fuel injection was originally vacuum operated. Platinum spark plugs have all been replaced in new designs with irridium spark plugs. Aluminum head were just coming into favor, as were aluminum blocks......which got off to a very bumpy start.
  • Fuel injection goes way back, the Germans used it at the beginning of WWII in their Bf109 fighter, provided quite an advantage in combat over the then-carb-equipped Spitfires and Hurricanes. Certain manuevers would cause the Merlin engines to starve for gas.

    The key to modern cars' combination of power, good fuel economy, and low emissions is the computer that coordinates all the different engine functions and technologies. Just having fuel injection or electronic ignition or variable cam timing or a turbocharger wasn't enough.
  • The carbureted Merlins could not fly inverted or at negative G's because of float-type carburetors..A Grumman Aircraft engineer invented the diaphragm (chain-saw type) carburetor and solved that problem in later aircraft..

    VERY few American-made cars had fuel injection in 1980...Nor did they have cam sensors or throttle position sensors. Cars built before 1975 had virtually NO electronics at all. The Bosch injection found on many European cars was 100% mechanical..

    Beginning in 1981, the first electronic engine controls appeared, producing some of the worst cars ever made..The lost decade...Some manufacturers simply paid Bosch licensing fees to use their injection technology and moved ahead quickly into the age of electronically controlled fuel injection.. Others tried to develop their own systems (Chryslers "lean-burn" and Honda's CVCC" but in the end, they ALL finally went to multi-port electronic injection and retired their 1950's engine designs.
  • The basics have been and always will be the basics. Air, Fuel, Compression, and spark in the right order gives you boom... Its amazing how many "mechanics" forget this.. It does not matter how many computers, sensors, and other witchcraft you use.. The basics are the basics.. Know them, love them !!
  • Many of the "blocks" of motors have been around since the '50's. There were a lot of changes in the '70's. Compare the motors of 1968 to 1978 and you'll see many changes in heads, fuel systems, and ignition systems. All to cope with pollution control requirements. Many of the items mentioned by OP were available in the '70's but were used only in a few vehicles, often higher end cars and California cars. These things became more commonplace and were put on all cars as pollution requirements got stricter. Remember CA started with pollution controls so CA cars had more "high tech" gadgets than the rest of the country for about 10 years.
  • Too bad that Studebaker was so far ahead of their time that people thought it to be odd.

    In a show room in 1985 I saw a Dodge Charger parked beside a 63 Avanti.

    in 04 or so GMC tried the Envoy XUV....a la Studebaker Wagonaire !

    Again , ahead of their time and as usual with most ''ahead of their time''ers, the needed technology just hasn't caught up yet, hence their demise.
  • "Too bad that Studebaker was so far ahead of their time that people thought it to be odd".
    Here are a couple of Studebaker firsts: 1) electric car in the early 1900s. The Nissan Leaf has nothing on Studebaker. 2) lockup torque converter on the automatic transmission introduced in 1951.
    If you put Nash into the mix, Nash introduced the heating system that brought in fresh air from the outside in the late 1930s. In 1954, Nash integrated the heating and air conditioning systems and had all the components under the dash or hood. GM had the evaporator and fans in the trunk at this time. Let's not forget that Packard made air conditioning available as an option before WW II.
