Making of the E46 BMW

This is a great video from youtube (lexusjoe) about the making of the E46 BMW.  The video is in Germany but is still full of great information, they are the guys who make the Ultimate Driving Machine at the end of the day.  This is a really interesting video that walks you through the whole process of making the E46 BMW, enjoy!

Building the Chassis and body of the E46 BMW.

The first stage of the process is building the chassis.  They assemble the front, rear and floor sections separately and then join them together. At this point you have the basic chassis to start building the E46 BMW.  Next comes the sides followed by some of the body panels.  The car then works it way around the factory getting more and more parts added as it goes.  The car shell is then prepped, painted and checked for imperfections and then left to cure.

The painted body is then place on the production line and parts are added piece by piece to the body this is where the car really starts to look like the end product.  They add lights, stereo, electrics,  windows, seat and more of the interior.  Followed by the doors and steering wheel.  The body is now ready to be mounted onto the drive train.

Then its time for the E46 engine. The engines are mounted to the transmission and then connected to the entire drive train.  Brakes, suspension, prop shaft, rear differential engine and transmission basically everything that makes the vehicle move.  The body of the car is then placed on top of the drive train and lowered into place.  A few adjustments to make sure everything is seated correctly and then they are secured together.

Finishing off the E46 BMW

Once the body is secured to the drive train they start adding the finishing touches such as the famous kidney grills, front and rear bumpers and the wheels.  The E46 wheels are connected with a really cool tool that secures all 5 bolts at the same time at the correct torque setting.  (I want one but have never seen it at my local DIY store).  They then add all the fuel, oil and lubricants.  At theis stage the car is completed and just need to be tested

The car is started and basic functional test are carried out to make sure the engine is running correctly and all equipment is working as it should.  The E46 BMW is then placed onto a rolling road which checks the brakes, engine under load, head lights etc.  Once the E46 passes all its test the car is ready to be sold and gets transported to the dealership ready for sale.  Next step your driveway.
