That OPs pic is a Mk7 photoshop job.
Recently VW released a few design pics and some drivetrain details.
For some damn reason, some people (car sites and mags) have kept saying the Mk8 GTI would be hybrid. WTF! But, VW is saying simply that the GTI will be 250HP, and R will be 350HP. Two very attainable outputs from revised versions of the current drivetrain. VW also stated it will be a revised MQB platform, 100 pounds lighter due to more high-strength steel usage.
VW is famously conservative with design, I suspect the Mk8 will be a handsome car also.
My concern for Mk8 will be the further cheapening of interior electronics, such as removing gauges for LCD panels, and knobs for touchscreens. Manufacturers do this to save money, and consumers think digital cockpit is cool?!?! Fuck I want to keep my buttons and I want my expensive, complicated electro-mechanical gauges. It's a car, not a smartphone!
I still think 2016 Mk7 was best version yet (for USA). You could get 2 door, MIB2 was standard, LP and PP were al la carte and the interior didn't have the cost cutters go through and remove lighted switches, CD player, under seat tray, etc.
I think Mk8 will be nice, but we'll have to see if it is truly NICER than a Mk7. Possibly just "more" standard power, standard VAQ and 7DSG will be only benefits over Mk7. Oh, and a different appearance.
