One of the main differences between the new BMW Z4 and upcoming Toyota Supra is that the former is only offered as a roadster and the latter as a coupe.

However, that line could be crossed, as a Toyota Supra Convertible/Targa is reportedly on the Japanese company’s radar.

The brand’s chief engineer, Tetsuya Tada, told CarSales that an open-top Supra might happen: “Of course we consider this”, said the exec.

There’s a long journey between considering and actually making it, though. Sure enough, Toyota has the foundation stone set in terms of research and development with the platform-sharing 2019 BMW Z4. But a Toyota Supra cabriolet needs to get enough votes to be approved for production. And it has to be feasible financially, so we wouldn’t hold our breath for it.

At the other end of the ‘what if?’ question is a BMW Z4 Coupe. If the Toyota Supra Convertible gets approved for production, then could we see a fixed-roof Z4.

There’s no apparent binding contract stopping either of the two brands from developing such cars, but that doesn’t necessarily mean they’re in the pipeline, as it would have to go through a very rigorous process.

Then comes the problem of assembly space, as the upcoming Toyota Supra is said to join the new BMW Z4 at Magna Steyr, in Austria. So, do you still think the Supra Convertible and Z4 Coupe could see the light of day, or was Mr. Tada simply playing the media?

We contacted both Toyota and BMW hoping that they will shed some light on the matter, so we will be updating this story if / when we hear back from them.
