2014 BMW 4 Series Convertible With M Performance Parts

It really was just a matter of time before the BMW 4 Series Convertible received the same BMW M Performance parts as its coupe brother. It surprisingly took more than a year for that to happen — the 4 Series Coupe received its goodies in July 2013 — but better late than never, right? The modifications bear a lot of similarities to the M Performance parts on the 4 Series Coupe and while that shouldn’t come as a surprise, BMW could have used a little more spice in decking out the convertible version with new goodies from its own M division. At least that’s my take on it. For what it is worth, the 4 Series Convertible does come away with a handful of M Performance upgrades. They’re mostly of the aesthetic variety on the exterior and interior, but there are also subtle performance modifications in the pipeline, including a new sports muffler and engine upgrades. My guess is that these M Performance parts are just the start of more in-house upgrades on the 4 Series Convertible. The model’s popularity among buyers will likely sway BMW into expanding its offerings for all variants of the 4 Series.
