AWD VW-AG group battle.
991 seems and is generation ahead of R8, Even V10 mid engine configuration, is not enough to make it better all around machine, even R8 have some adventages.
Its very close overall. But its amaing what progression 911 did compared to 997 version.
The bad thing - 991 makes inside the company own competention, reducing the sales of R8 which on paper as more dedicated sports car should be faster, but isnt.
