BMW Invents Special Door Handles For Future CSL Models

"Such a loop handle door opener is often associated with the sportiness of a motor vehicle, and loop handle door openers are popular optical tuning aids," the patent states.

In actual racing cars where every gram matters, loops do save weight. But it's telling that Bimmer's most recent lightweight special, theM4 CSL, is equipped with standard door handles. In fact, mosticonic M carshave traditional door handles, not even in the new 3.0 CSL. So what we have here is an "optical tuning aid," which is fancy patent speak for helping your car look hella fast.

There are actual benefits, however. But first, a closer look at the new invention, which uses an existing BMW door handle and can therefore be retrofitted to several cars. Or it could even debut on a future CS or CSL model.

A standard door handle is coupled to a door linkage leading to a tensile force transmission element and a door lock. You don't need all of this in a racing car, so a simple high-strength loop is coupled directly to the tensile force transmission element. Using this method, you save the weight of a fancy door handle and some cabling.

That's why BMW is proposing this new loop handle, which slots neatly into the existing door assembly. It consists of the loop and a new tensile force transmission element that will snap lock onto the existing mechanisms. BMW says this can be done without tools, and the standard handle bar is retained.
