Perry given the sharing of parts you mention I have often wondered why someone would choose to pay the premium for the A5 over a Skoda model as they have come on in leaps and bounds in recent years.
As Howard mentions the Kia/Hyundai/Toyota layer is now so capable that I am having trouble seeing the difference other than brand perception and it's reflection on me as people see me get out. The differences within the fold at VW/Audi/Seat/Skoda are becoming even more blurred.
Only meant in an inquisitive manner do you feel there is really still a difference in the A5 vs say a Skoda Octavia.
Same engine range in them 1.5 TSFi, 2L D in various tunes etc.
Same Audio/IT with different buttons
Same options for everything
I don't see the interior materials being significantly different these days.
Do you feel there is a real difference?
Don't want to get all techie and geek out on this but you can't compare Audi and Skoda whatsoever - aside from A1/A3 but even there it's only slight underpinnings that are shared from an engineering point of view.
VAG does share engines but from there, it's down to what architecture it's fitted to. A Skoda has a transverse engine layout where as Audi is longitudinal. 4 wheel drive systems are also unique to each engine layout. As far as tech, Audi's is there own set up and not just buttons whereas VW has their own electrical systems. The only Audi that shares a VW sourced system is the A1. VW on the other hand use a form of Audi's navigation/infotainment in the T-Reg.
In can be a tad confusing. But the often easily made comment that an Audi is a dressed up VW is far from the truth and having worked behind the scenes, there isn't much to compare really.
Please note, this is speaking against products from A4 and up. While the A3 is much aligned to the new Golf, Audi doesn't simply take what VW builds but rather fits their own tune across all key systems.
JLR on the other hand are hands down the ones to look at when comparing what is hared as it's almost all shared!
