Huh!
997 Turbo faster on the track as well. Difference is not big, but I honestly expected much, much more from R8 5.2 FSI...
Porsche achieved 4L less fuel consumption then R8 V10. 997 Turbo was also better at handling... To explain little bit-it is latest MY09 997 Turbo manual with LSD and latest software for its PTM AWD system.
Both cars were on standard tires.
Further bad news-I received email from my Motorpresse friend-both AMS and Sport Auto are currently testing two examples of R8 5.2 FSI. Results are not great at all...
