Honestly, while those videos
Honestly, while those videos make great entertainment, they aren't a measure of much. You have a dozen cars with a dozen different drivers of different expertise. If you look at the #3 (latest), you'll see that in the beginning, many of the drivers lose traction because they aren't familiar with the vehicle and how it performs from a zero-start. Having driven the Audi R8 V10 and Viper SRT V10 as well as the 2013 GT-R, all on the same track, I would definitely give the straightaway to the R8 and Viper (probably the Viper overall, but that's a hard call). The main advantage the GT-R has is its extremely awesome cornering and general handling characteristics for the amateur (which I fully admit to being).
