As a vehicle salesman (of American car & trucks) I recognize things many consumers don't. I hope to assist the the person who lives by happen on some helpful tips.

How lengthy Does that Take?

Let's Look earlier a Bit...

Did you ever wonder just how long that takes to make a car? the is method less than you think. But prior to we look in ~ the actual numbers let’s look in ~ some background and climate agree on part definitions.


The finest example of old-time vehicle manufacturing is the design T. Henry Ford is credited with revolutionizing the automobile industry, but he walk much an ext than that. That revolutionized manufacturing in general—across all commercial categories. That did this through standardizing parts, limiting options, and also choosing products that were amenable to fast assembly. Most importantly, he arisen machines the were design to one of two people independently attain tasks or assist workers and speed increase the process. Was he successful? Let’s put it this way. He and his staff come up with solution that diminished the over every assembly time on a version T native 12.5 hours to 93 minutes. The is a pretty exceptional 87.6% palliation in production time.

Things have Changed

How does the compare with today’s assembly time? it is not a fair comparison. Today’s vehicles space a good bit more complicated than in 1925. They are expected to be safer, manage speeds the were unheard of in 1925, and last for years and years.

One the the things that Henry Ford’s factories did the is even an ext relevant today is the use of preassembled parts. So, let’s agree on part definitions. As soon as I am talking around how long it takes to “make a car.” ns am referring to the amount of time the takes come assemble all the components that have actually been lugged together come the final assembly plant. The assumes that there are plenty of assemblies or sub-assemblies that are coming to the plant ready to install. That appears to miss out ~ above a an excellent deal of the overall manufacturing process, yet it still contains a great deal that work.


The bodies space stamped out, interiors installed, wiring harnesses put in location – it is a big job. Toyota estimates that the SUV’s have around 30,000 parts. Part may involved the last plant as component of one assembly ready to be integrated into the brand-new car. Some comes in as raw materials that are fabricated top top the spot.

Making the Body

A good bit that the vehicle comes to the final assembly plant ready to it is in installed. Things prefer seats, radios, wiring harnesses, and also motors to run all the miscellaneous power equipment all involved the assembly plant ready to install. The body itself, though, is typically made at the final assembly plant and also guides much of the assembly process.

The human body assembly is amazingly complex. Steel of many different species is stamped and molded into shape. The various materials are closely placed follow to the engineers' style and carry out for things choose crumple zones, penetration protection and cabin integrity. The various products are robotically welded right into a unit the superficially looks choose a car, known in the sector as a "white body."


The white human body is climate inspected both by laser-guided systems and also by hand. From over there it it s okay cleaned, coated through an undercoat, dried and also re-inspected. If it passes inspection, it gain its color coat the paint, an additional drying, and also then clean coating. The final step is a couple of minutes in an oven to roasted the finish and harden the paint. Just then does it get in the production line to be mated up with an interior, drivetrain, and remaining parts.

The Total?

So, we have actually cheated a bit by just counting the time it takes because that the last assembly. It would be difficult to track the production time ~ above every screw, nut and bolt.

There is a great deal that variability in assembly time. The entire process varies from car to car and also manufacturer come manufacturer. Car with several hand work, favor a rolfes Royce deserve to take increase to six months come produce. Rolls Royce has actually very minimal sales and also the slow production time is not an issue. Besides, many people expect the slow manufacturing speed and assume it enables for a higher level of high quality and an individual attention.

What is amazing is the rate at i m sorry high production cars and also trucks can be turned out. Toyota release a an extensive amount of information around their production procedures and figures. They estimate that a fine appointed car, truck or SUV takes around 17 come 18 hrs to assemble. Various other manufacturers have similar numbers. Some lesser appointed vehicles deserve to be assembled as quickly as 11 hours.


The surprising part is the they space coming turn off the production floor around one automobile every 45 to 90 seconds. The largest plants are turning out over 400,000 car a year.

The Past and the Present

I recognize what you are thinking. Henry Ford was popping cars out v an assembly time that 93 minutes and that is method more impressive. Yet is it really. Ns think the is tough to compare. What that did to be amazing. He to be a true groundbreaker that adjusted manufacturing and contemporary life for united state all.

Granted the rate at i m sorry he can turn out a car was - and is - impressive. However let's make certain we are comparing apples come apples.

The automobile Henry Ford was producing had about 1481 parts. The existing Toyota SUVs have around 30,000 parts. So instead of looking at complete assembly time, let’s look in ~ the number of seconds that takes to install a component on a version T and a modern-day car. The version T through its impressive 93-minute assembly time, compelled an median assembly rate of 3.76 secs per part. Today’s Toyota manufacturing procedure is way faster. They are averaging 2.04 secs per part.

Finally, what perform you think takes longer to download a 2-speed transmission with cotton and wood linings, or one 8 speed all-wheel drive transmission v as countless parts as the whole Model T?
