Wow, this is kind of surprising. I imagine that the tS will beat the 12C to 60, but I would have thought after that the 12C should/would take. In the turns, it depends. On longer/faster turns, I'd think the 12C should take. On super tight turns, the all wheel drive and steer should help the tS take. But quarter of a mile+, I would think the 12C would be faster.I borrowed a 991 turbo S for the day and its faster on the road than my 12C Spider. So much more torque. The P13 will need outputs not much below the 12C to compete.
Could you elaborate on what you mean it's faster on the road. Just outright faster, or like 0-60 launches on the streets?
