Discover the Porsche 918 Spyder Manufacturing Process

Behind every great car is an advanced manufacturing facility and it is absolutely no different for the Porsche 918 Spyder hybrid hypercar. Made at the German firm’s Stuttgart-Zuffenhausen plant, Porsche goes to great lengths to ensure the quality and highest craftsmanship for each and every 918 heading to customers.

One of the most crucial elements in the production of the Porsche 918 Spyder is the assembly elevating truck. It is battery operated and carries the car’s monocoque into position for the interior, battery and wiring to be installed.

Elsewhere, the drivetrain assembly element of production uses scissor lift platforms to position the car’s monocoque for the electric motor and transmission module to be installed. A specific wheel alignment platform has also been created specifically for the Porsche 918 Spyder.

Leather finishing and assembly tables are also used in the hypercar’s manufacturing and each of these tables can be adjusted to perfectly suit each individual employee to ensure their best work. Another interesting piece of tech used to create the 918 is Bluetooth-controlled cordless screwdrivers used for the very first time at Porsche.

As a reminder, the Porsche 918 Spyder uses a mid-mounted 4.6-litre V8 engine producing 608 hp independently – the highest specific power of any naturally aspirated Porsche engine. The V8 is then supplemented by a further two electric motors mounted on each axle. The electric motors can either drive the wheels independently or work together with the engine to boost performance. Each motor produces enough power to boost the total figure to an amazing 887 hp. A seven-speed Porsche Doppelkupplung (PDK) controls power delivery to the rear wheels.

“Ergonomic and reliable: The Porsche 918 Spyder manufactory

Stuttgart. The Porsche 918 Spyder manufactory in Stuttgart-Zuffenhausen is a real eye-catcher – both visually and in terms of the processes and variety of new developments in the field of assembly and quality assurance that take place there. Patent applications are currently pending for some of these innovations, which fulfil the very highest standards particularly when it comes to ergonomics. These innovations emphasise the fact “that our definition of innovation goes well beyond the vehicle itself”, as explained by Michael Drolshagen, who, as Director of Production, was involved in the designing the manufactory and who oversees the activities that go on there today. The examples below give an overview of the ergonomic innovations in use at the plant:

Scissors lift platforms
The scissors lift platforms enable ergonomic assembly of vehicles, starting with the interior and working outwards to complete the exterior. The scissors lift platforms move from station to station at the push of a button, making the technicians’ work considerably easier when they need to fit a 140-kg high-voltage battery at the rear of a vehicle, for example. In addition, the scissors lift platforms ensure that the bodyshell can be fitted without causing any damage.

Assembly elevating truck
The battery-powered elevating truck has been designed especially for the Porsche manufactory. The truck carries the two-seater monocoque, which is the starting point of assembling the Porsche 918 Spyder. The elevating truck allows the monocoque shell to be rotated, tilted, lifted and lowered, meaning the interior of the vehicle as well as the 12-volt battery and the high-voltage wiring can be positioned with great ease. The ability to position components with ease is, in fact, the key to preventing damage when fitting the components.

Drivetrain assembly
During the “engagement” process, the electric motor and transmission module is connected in a de-energised state to the engine with the help of a specially developed trolley. Together, these components form the vehicle’s drive unit. At this point, the specially designed scissors lift platforms are used: They position the unit carrier above the drive unit so that both elements can be screwed together at three different points. The next stage of the process is called the “marriage”. The marriage involves the unit carrier and the drive unit being connected to the monocoque via six bolts.

Wheel alignment platform
Thanks to the new wheel alignment platform in use at the manufactory, all the essential parameters can now be measured within a very small space. These parameters include properties such as the cross load, track and camber, and each one can be configured to the optimum setting for the vehicle.

Leather finishing and assembly tables
The leather finishing and assembly tables used at the 918 manufactory set the benchmark when it comes to ergonomics and flexibility. For example, interchangeable inserts allow different components to be manufactured, ensuring that station times are fully utilised. Furthermore, the height of the tables can be adjusted along with the angle so that the table corresponds to the needs of the individual employee.

Bluetooth-controlled cordless screwdriver
The Bluetooth-controlled cordless screwdrivers are being used for the first time at Porsche. These screwdrivers endorse the philosophy at the manufactory because they work virtually silently and require no wiring. These features give the technicians maximum flexibility, and the risk of damage to components is greatly reduced. What’s more, coupling the screwdrivers with the database via a Bluetooth interface ensures that the torque values for all safety-specific screw connections are complied with and can be documented and checked at any time.

Electronic vehicle tracking card
The electronic vehicle tracking card, known as the eWbk for short, may not be an innovation for the Porsche 918 Spyder manufactory, but it clearly shows how the Zuffenhausen site – home to the 911 production line for five decades – has been able to effectively combine small-scale and large-scale production. A standard feature of large-scale production for many years, the eWbk system used at the manufactory also contains a wealth of information that is essential to the production process, including drawings and test points to name just a couple. In addition, the card can be used to document potential problems – perhaps if the feedback from the Bluetooth-controlled cordless screwdriver indicates that a particular torque was not reached.
