Talk:AUDI R18 E-TRON QUATTRO (2014)/@comment-29423614-20170619025717/@comment-31374292-20170620092935

Yes, you should buy the Audi2014 if you have the RS but I suggest to only upgrade it with racing dollars (even in RS it costs a fortune, you will see). DoN't upgrade the Audi with gold because it costs too much.

If you have both the Audi and the Porsche, you only need to upgrade the Porsche 919 2014 to PR94 to reach the 10 lapper.

This is the most gold efficient way to reach the 10 lapper in ÍEndurance Kings.
