New Patent Filings Reveal More of Turbocharged Suzuki Recursion

Last month, we broke the news of patent filings for the technology behind Suzuki‘s turbocharged Recursion concept. Today, we offer a second patent application with additional information about the technology and more detailed illustrations that more closely resemble the concept model.

But before we get any further, let’s get something straight first: unlike what some other sites are reporting after getting the patent information from us first, these patents applications are not definitive proof that Suzuki will bring the Recursion to production. The two patents reveal some of the technology that went into the concept model, but neither shows any indication of further development beyond that. Manufacturers file patents all the time, and sometimes the ideas in the patent stop at the concept stage. Of course, there’s fun in speculating, and patent filings give us some insight into how manufacturers think.

The Parallel-Twin described in the second patent resembles the engine from the earlier patent. Note the turbocharger (#30) and the intercooler (#28).

In the case of the second patent, published today by the USPTO but filed on Oct. 6, 2014, the illustrations include the concept model’s half-fairing, fenders, brakes, and other details that were left relatively sparse and simplified in the earlier patent filed on Sept. 24, 2014.

The second patent offers more details left out of the earlier one.

The earlier patent focused on the designs for the intercooler while the second delves more into the positioning of the turbocharger to optimize pipe routing to reduce weight while contributing to a lower center of gravity. With the turbo located below the radiator and behind the front wheel, the patent calls for a protective covering (hence the added bodywork in the drawings.) The airbox is located below the engine, reducing the length of piping required to reach the turbo while also lowering the center of gravity.

The new patent also describes the intake ducts (122a and 122b in the diagram below) on the front of the half-cowl to draw air for cooling the surface of the intercooler, an idea also mentioned in the earlier patent.


Will we ever see this technology applied to a production model? It’s possible, but there’s nothing in either patent that suggests we will. For that, we would need to see more an evolution from the concept model, such as the addition of rear turn signals, less funky-looking brake discs and perhaps a passenger seat.
