Factory build process of the Porsche 992 911 GT3 with a paint to sample finish.
It is no small feat to craft a 911 -1,500 workers touch each car during its two-day long assembly that starts with a shell and finishes by rolling off a line. Now, for the first time, a time lapse video shows the entire process, focusing on a very special 911 GT3, part of the Paint to Sample program.
With dozens of individual options to choose from, the range of possible combinations means seeing a pair of identical 911s is particularly rare. Color choice plays a large role in the customization. To meet increasing demand and improve ease of access for customers, the popular Paint to Sample program offered through Porsche Exclusive Manufaktur was updated in late 2021 to expand its capacity. The significant long-term investment from Porsche highlights the marque’s commitment to building anyone’s dream car. Including standard offerings on each model line, more than 160 pre-approved paint options are now available in the current catalog.
In the Zuffenhausen plant where the 911, 718 and Taycan model lines are assembled, an additional color mixing bank added capacity to complete more Paint to Sample configurations without slowing production. “In reaction to demand, we made a big step now and went from five cars a day to 20 cars a day, which means 120 cars per calendar week from Paint to Sample,” said Boris Apenbrink, Head of Vehicles at Porsche Exclusive Manufaktur.
In detail: creating a Paint to Sample Porsche
Prior to its 117-stage assembly, the 911 chassis has spent more than a day going through preparation in the body and paint shop. One of the challenges of painting vehicles and developing paint finishes is working with the material mix of the underlying components. A vehicle body already consists of several different steel and aluminum materials and can also include carbon fiber or polypropylene. Paint batches must suit all exterior features equally and produce the same color.
Before entering the paint shop, the body is degreased, given a phosphate coat and put through an electro-chemical process chiefly used for corrosion protection. During the coating process, the body is dipped into a basin, which is filled with electrophoretic dip paint and deionized water. To achieve optimal coverage of the body, it is rotated around its own axis in the basin.
From here a primer, base coat and clear coat are applied to the body and panels, with a standard color using about 4 liters of liquid application between the three stages. Primers are chosen based on final color; light colors require light primers, dark colors need dark primer. The base coat is the colored layer which delivers the requested hue and is only up to 30 micrometers thick. To put that into comparison, a standard piece of printer paper is around 100 micrometers.
The car’s final layer, the clear coat, is its thickest and is sprayed between 30 to 50 micrometers, illustrating just how thin the individual paint coats are. The painted car is then dried at a maximum temperature of 392˚ Fahrenheit (200˚Celcius) for more than two and a half hours. “A lot of customers want to underline their personality with their car and bring their flavor into the car concept,” said Apenbrink. “Nothing underlines personality as well as the car color because this is what tells the story.”
Standard, metallic and special colors are specifically defined in advance for each model line in the series and, in some cases, even for each derivative for each model year. The quantity of colors offered is determined by the number of storage tanks and paint supply lines within the paint shops at the production plants. For this reason, no more than 17 standard exterior colors can be offered from a purely technical standpoint for the 911.
With Paint to Sample, more than 100 additional pre-approved colors beyond the standard offering are available from the factory on a new 911 or 718. The Taycan, Cayenne, Panamera and Macan have more than 50 additional choices available. New hues can be considered as well via the Paint to Sample Plus program if a customer wants to take it a step further, a process that can color match almost any request as long as it passes a rigid feasibility test.
