2013 BMW 4-Series Convertible spy shots
A world debut, however, could take place sometime later this year.
From these spy shots it’s clear the convertible will feature an automated folding hard-top, just like the one on the model it’s set to replace. Sadly, however, it appears as though the current model’s strangely proportioned rear is here to stay for at least another generation.
What isn’t so clear is what name BMW will pick for its new 3-Series based coupe and convertible. While there’s a chance the cars will remain in the 3-Series family, there are suggestions they may adopt a new 4-Series moniker. Thus, the prototype you see here may be for a new 4-Series Convertible.
More importantly, it would also mean that the two-door versions of the M3 could arrive as M4s, which helps to explain why we’ve been seeing plenty of M3 Sedan prototypes but barely any coupes despite the two-door traditionally arriving first.
As for the engine lineup of the regular models, expect the same four- and six-cylinder engines from the 3-Series sedan to filter across to the convertible. This means a 240 horsepower 2.0-liter turbo in the base model and a 300 horsepower 3.0-liter turbo in the range-topper. Transmission choices should include a standard six-speed manual and optional eight-speed automatic.
