Acura's version of Honda's General Motors-based electric crossover will inaugurate the ADX nameplate, according to a recent report. While nothing is official, the United States Patent and Trademark Office recently granted the Japanese company the rights to the name.

Spotted by Car & Driver, the trademark application was filed by Honda on December 22, 2021, and approved three days later. Nothing suggests it's for a Honda, but a model called ADX would slot neatly into the Acura range, which also includes the MDX and the RDX.

The filing asks more questions than it answers. What's an Acura ADX? One possibility is that the nameplate might appear on Acura's version of the Honda Prologue, which is due out for the 2024 model year. It will be based on a GM-designed platform, and it will be powered by the same Ultium battery technology found under the Cadillac Lyriq, among other EVs. We know it will spawn an Acura, too.

It's important to note that nothing in the filing mentions an electric powertrain. Acura's range only includes two crossovers, which is far below the industry average (Lexus has five crossovers and SUVs; even Lincoln has four) so the ADX name could end up on a non-electric addition to the range. The line-up could grow in a number of directions and many of its dealers are asking for bigger and small people-movers.

As we've said before, a patent or a trademark filing is not a guarantee that a feature or a nameplate will see the light that awaits at the end of a production line. Carmakers routinely protect their intellectual property to ensure that it doesn't end up in the hands of a rival. Although there's no such thing as an Acura ADX — at least not yet — the name falls in line with the company's naming system.
