BMW is working on a mildly updated version of its two-seater roadster, as proven by this camouflaged prototype of a Z4 caught out in the open. The BMW Z4 G29 was originally introduced in 2018, which means it will be four years old very soon. Thus, 2023 is probably the right time for the Bavarian automaker to unveil a facelift, which is expected to be focused on new tech rather than design updates.

The body of the Z4 prototype was completely covered with camouflage wrap, but the lines on the bumper look nearly identical to the current Z4. The trim on the intakes appears to be slightly different, while a few changes could be hiding below that grille cover. Another possibility is for BMW to tweak the LED graphics on the headlights, with production units appearing later on in the development process. Moving over at the back, the designers took a day off since nothing appears to have changed. Even the diffuser trim and the dual tailpipes are carried over from the current model. Again, BMW could introduce minor changes later on, although one thing is for sure – the third-gen Z4 will remain instantly recognizable.

 

While BMW recently gave the Z4 more standard equipment including a digital instrument cluster, the facelifted version could benefit from the Curved Display which gradually finds its way into the entire BMW lineup. It comprises a 12.3-inch digital instrument cluster and a 14.9-inch infotainment touchscreen in a single panel which would look rather odd inside the roadster. Still, it would bring the Z4 closer to the rival Mercedes-AMG SL 43. in terms of tech and connectivity features which is a major aspect for new car buyers.

As for powertrains, we expect the current lineup to be carried over, with the rumored return of a six-speed manual gearbox option to the M40i flagship. The same update was recently introduced to the Toyota GR Supra which is closely related to the BMW Z4. In any case, the facelifted Z4 could be the last of its kind for this decade at least, following the fate of the Mercedes-Benz SLC / SLK which used to be its direct rival. Roadster sales are not high enough to justify development costs for a new generation, and the only hope is a partnership with another automaker. If BMW decides to green-light an all-new fourth-gen Z4, then we would be talking about a fully electric roadster, dictated by the zero-emission regulations in the European market by 2030.
