I find these rolling starts both boring and unrepresentative of the cars' true potential, even though the Balboni is clearly the quicker car. Other than that... the R8 V10 has a much better sound than the SLS. The Lambo trumps them both in that department though.
Balboni is quicker than the SLS and the SLS is much better than the R8.Kinda a little strange with the R8 having a similar V10 as its cousin. And this also amazes me because SLS beats 997.2TT around tracks yet is probably way slower in straight line. SLS handling has to be tops.
Located in Sweden, as far as I remember it is the airstrip used by Koenigsegg for testing. He even drives one of his cars in an older video.
The rolling start makes sense to reduce wear on the drivetrain, a standing start will delute the actual performance of the cars due to the variation of launch techniques.
