Porsche continues to roll out lightly camouflaged testers of its 991 series, with our spies placing their cameras’ focus once again on the 911 Turbo – you know, the all-new model that went on sale in the last quarter of… 2013.

We don’t expect the pending facelift of the 991 series to arrive for at least another year if not two, but even when it does, Porsche’s prior history suggests that there won’t be any drastic alterations to the design (in fact, you can freely say the same for complete model changes).

On this prototype, which may or may not sport all upcoming updates, we noticed the covered up from bumper and tail lamps, plus the new three-slat air outlets on the corners of the rear bumper.

The real interesting part about the refreshed 911 Turbo should concern the improvements on the chassis and possibly the boxer unit hanging out at the back, but at this point, there’s no information for either.
