If you’ve been following the news on the Mazda RX-Vision Concept, you’re probably hoping it heads to production as the RX-9. Unfortunately, there are contradicting reports on whether the RX-9 is really in development, and we will likely know more at the Tokyo Motor Show this year if Mazda debuts anything. But to give us some hope, a recent patent application has been published that hints at a new door design for a Mazda sports car, suggesting this could be used on the RX-9.
The design isn’t anything fancy or crazy, and it’s certainly not something we’ve never seen before. Like Mazda says in the patent application, low-slung sports cars tend to have an issue when it comes to the potential for their doors to hit curbs when opened. There’s a reason why cars like modern McLarens have fancy doors – it’s not just because some people think they look cool.
But Mazda isn’t looking to produce a McLaren or a fancy Mercedes SLS AMG. If the RX-9 does head to production, it likely won’t be an extremely expensive sports car, which means certain components can’t be expensive to produce or use. In the patent application, Mazda talks about how gas struts are “relatively large-scale, heavy and expensive.” Gas struts are typically used for holding a vertically hinged door open.
Another option is using a coil spring, but Mazda notes “it has substantially the same scale as the gas damper and its energizing range is difficult to expand.” So the company’s solution is to use a torsion bar to hold the door in place.
Rumors say the RX-9 will debut at the Tokyo Motor Show in late October, so we still have a couple months of waiting to see if Mazda is planning on a new sports car.
