The members of one of the many model-specific forums sprouting on the internet these days, have purportedly gained access to a snippet from an official BMW document listing a number of details including the production dates and model trims for the upcoming 4-Series range, which was teased through a coupe concept at last month's Detroit Motor Show.
For starters, the list states that the F32, which is BMW's code-name for the coupe, will be offered at launch in four flavors – the 428i and 428xi (all-wheel drive) motivated by a 2.0-liter turbocharged inline four (likely delivering 240-horses), and the 435i and 435xi featuring a 3.0-liter turbocharged inline-six (with 300hp unless BMW uses its more potent 315hp unit).
Series production of the 2013 model Coupe will begin this July at BMW's Munich factory and will end in June of 2014, when the new model year kicks in.
The Convertible version codenamed F33 will be offered with the same two engines in the 428i and 435i, but only all with rear-wheel drive. Production starts at the BMW's Regensburg factory in November of 2013 and ends in June next year.
In both cases, the last date refers to the end of production for the specific MY (Model Year), not the series, which at that point, will continue with a new model year that may or may not bring some updates.
