As it is the case with all other members of the 4-Series lineup, the hard-top cabrio will only receive subtle cosmetic tweaks from BMW’s talented designers. That’s hardly surprising taking into account the 4-Series Convertible has been on sale for less than three years and looks quite fresh, so it does not really need a significant makeover. This prototype right here was rocking an optional M Sport package and had some disguise to hide just about the same array of visual enhancements the other derivatives are set to receive. These changes, including new full-LED headlights, will most likely be visible only to die-hard fans of the Bavarian marque, though.
All of the exterior and interior updates the 4 Series family will feature are going to bring the models in line with the facelifted 3 Series range that came out last year. However, we are not so sure the turbocharged 1.5-liter gasoline unit from the 318i will also find its way in the engine bays of the “4”-badged models. After all, why would anyone buy a 4-Series Coupe/Convertible/Gran Coupe with a three-cylinder engine from a Mini? The only answer we can find to this question is the lower starting price, with the 318i being €4,550 cheaper in Germany than the four-cylinder 320i.
While the LCI for the current 4-Series will not bring any dramatic changes, the next-gen will. Codenamed G21, it’s due to come out around 2021 and will allegedly make the switch from a hard top to a fabric roof. Although we are fans of convertibles with metal tops, we can’t deny the fact that a fabric roof makes the car lighter and also more practical since it occupies less space in the trunk when folded. 2021 is still a long way to go, so a lot could happen until then.
The only photos we're missing right now are those of the M4 Convertible, but don't be too surprised if these will pop up in the near future. Until then, you can check out our spy images showing the M4 Coupe which we spotted a few days ago riding on the GTS' orange wheels.
