Just look at these acceleration numbers:
Audi R8 5.2 FSI V10 Plus S-tronic
- 0-100 km/h: 3,5 s
- 0-160 km/h: 7,0 s
- 0-200 km/h: 10,4 s
- 400 m: 11,2 s (209 km/h - 129.8 MPH)
- 1 km: 20,5 s (263 km/h - 163.4 MPH)
- Vmax.: 319 km/h
Porsche 911 Carrera S X51 Powerkit (manual)
- 0-100 km/h: 4,5 s
- 0-160 km/h: 9,5 s
- 0-200 km/h: 14,3 s
- 400 m: 12,7 s (186 km/h - 115.5 MPH)
- 1 km: 22,5 s (244 km/h - 151.6)
- Vmax.: 306 km/h
It's completely one sided. firstname.lastname@example.org 1/4 mile versus 12.7@115? That is not even remotely close or fair, it's a beatdown. A 542 horsepower all wheel drive dual clutch 5.2 liter V10 versus a 3.8 liter 430 horsepower rear wheel drive manual flat-6 will tend to be a bit one sided. What were they thinking? Still, impressive to see just how fast the new Audi R8 V10 Plus is.
On the roadcourse the 991 actually does admirably only losing by 4/10's with a 1:22.89 versus the R8 1:22.58. That is not bad at all considering the huge power disparity and the transmission handicap.
Interestingly, the magainze picks the 991 over the R8. AudiBoost does not speak French but it probably has something to do with driving pleasure and price. If the price is not a factor though, hard to argue against the R8. It's simply a beast.
