Have a look at the latest F33 4 Series convertible prototype, revealing more of its defining characteristic - its metal folding roof. Earlier spyshots (reposted below) show the hard top operation and the design is largely similar to the current E93 convertible.
The F33 will share the same engine and transmission options as the F32 coupe, as well as the coupe’s general styling. So, imagine the coupe that you’ve seen revealed, but with this metal folding top.
Production of the 4 Series convertible (both 435i and 428i) begins later this year - in November 2013.

It’s been a busy test week for BMW at the Nurburgring, which includes some more testing on the F32 435i M Sport. Not much is revealed in these photos, but they provide more looks at how the 4 Series (F32) looks in motion.
This is a 435i M Sport in Estoril Blue II. The M Sport bumpers remain under camouflage. The headlights feature the optional full LED headlights with squared-off corona rings.
The M Sport brakes are fitted, but the M Sport wheels are not. See the wheels 4 Series lineup (from the 4 Series order guide) posted below for what the M Sport wheels will look like (as well as on the blue 4 Series spotted at the airport reposted below).

Will we be seeing the F32 4 Series coupe make its public debut at the 2013 Shanghai auto show in just over a week?
These photos are purported to be production stage 4 Series coupes at the airport waiting to be loaded for a plane to Shanghai. They may look like they are wearing the usual pre-production prototype camouflage, but per insider Scott26, the camouflage is just protective vinyl for the trip.
Although the production 4 Series coupe has recently been spotted completely revealed [pics below], we have not yet seen the M Sport version (which is represented by the Estoril Blue 4 Series seen below).
The 2013 Shanghai auto show begins on April 20th. Keep your fingers crossed

Now that we have seen the production 4 Series coupe fully uncovered, a natural comparison to draw is between the 4 Series coupe (F32) and the model that it succeeds, the 3 Series coupe (E92).
We do not yet know the official dimensions of the production 4 Series coupe, but for reference the concept 4 series dimensions are:
1.6 inches longer than E92 3 Series coupe
1.6 inches wider than E92 3 Series Coupe
1.3 inches lower than E92 3 Series Coupe
1.9 inches longer wheelbase than E92 3 Series coupe
1.7 inches wider front track than E92 3 Series coupe
3.1 inches wider rear track than E92 3 Series coupe
Note: these are calculated using concept (not production) 4 Series dimensions
We have updated with even more photos of the BMW F32 4 Series (435i) coupe in Sport Line, showing even more angles. Enjoy!
Caught during a night time photo shoot is this production F32 4 Series Coupe, which gives us the first ever look at the final (and uncovered) 4 Series!
This 435i coupe still looks unique, sleek and sporty despite its toned down front fascia, rear bumper and side view mirrors designs (compared to the concept model). The unique tail lights from the concept version also have not been carried over from the concept. The headlights seen here are the optional full LED headlights.
This appears to be a Sport Line 4 Series model. The wheels are the optional 19″ Style 407 wheels.
Also as expected, we now see the functional air breather vents in the front fender, which began appearing with the 3 Series GT model and will … CONTINUED
We have added some additional info and pages from the dealer order guide for the BMW 4 Series Coupe, showing samples of the available paint, wheel, upholstery and interior trim.
U.S. BMW dealers have now received order forms for ordering their first demo 435i and 428i coupes (just as they did recently for the 2014 X5), and the forms give us a good general preview of the different lines, options and packages to expect for the 2014 BMW 435i and 428i (U.S. configuration).
Not much surprises on here, but it does show that full LED head lights will be available on the 4 Series (just as we spied up-close yesterday) and it may be equipped with the new 609 Navigation Professional system. There are also some new M Sport wheels options (Style 441M and 442M).
Like the F30 3 Series, the 4 Series coupe will be available in “Lines” but it does not appear to be … CONTINUED
