SPIED: 2013 BMW 3 or 4 Series Convertible with Retractable Hardtop

Until BMW makes an official statement on what it has decided to name the replacements for today's 3-Series Coupe and Convertible models, we'll have to keep using both the 3- and 4-Series monikers to describe the two-door body styles of the Bavarian maker's most popular model.

Over the past few months and aside from the official presentation of the sedan in October, we have shown you spy shots of the next M3 sedan, the 3-Series Touring, the 3 or 4-Series Coupe, and the 3- or 4-Series Gran Turismo fastback, but this is the first time we're sharing scoops of the Convertible model.

SPY SHOTS: Six-Cylinder BMW M3 F30 Sedan Spotted on the Road

With the unveiling of the 2012 BMW 3 Series sedan all done and dusted, the Bavarian automaker's engineers have now turned their focus on the other variants of the F30 series including the flagship M3 sedan that was captured by our spies testing on the streets of Germany in a fairly light disguise.

While BMW has done its best to hide the most telling styling features of the M3 such as the shape of the front and rear bumpers, the pictures expose the car's muscular front and rear fenders that house larger alloy wheels and brake sets, as well as the beefier rocker panels.

BMW Releases Teaser Film on Mystery New X6 M Model, Could it be the Diesel?

Those Bavarians are always coming up with something to grab our attention. Their latest mystery film is about a new edition or model of the X6 with the famed M logo.

The only official information we get from BMW is that the vehicle seen in the teaser clip will establish "a new category of automobiles" and that it represents "a new chapter powered by M".

The vehicle itself or rather certain parts of the crossover like the lights, hood and, of course, the moniker on the tailgate, are craftily blurred out.

Spied: Is BMW Working on a 7-Series-Based "i" Sedan?

It's no secret that BMW intends to market a whole line of advanced dedicated hybrid, range-extended and plug-in electric models under its new "i" sub-brand.

The question is, what's up next after the presentation of the i3 hatchback in 2013 and the i8 sports coupe in 2014? While BMW is keeping mum about its future plans, our spy photographers captured a strange looking 7-Series prototype, seemingly based on the standard ActiveHybrid 7.
