Honestly I have always been looking at these numbers with a bit of scepticism. For sure my car is fast, and much faster than a stock 35i. But... 370 whp? It is really a lot, i thought...
That until yesterday.
I had the opportunity to race a 2012 911 Carrera S (991), brand new (and marvelous)... It comes stock with 400 chp and 1490 kg. The Z435i weights 1600 kg, as reference.
Everything happened in less than 30 second, I guess. We met on the highway @ 150 km/h aprox, I was in 7th gear (DCT). He passed me slowly, than accelerated. Great opportunity: manually downshift to 5th and try to catch him. We remained at the same distance all the time, he couldn't take advantage at all until my speed-limiter (250 km/h) said "game over".... and he disappeared. He was WOT? Impossible to say, but i guess he was, observing how fast desappeared when I should cut.
Summary: NOT BAD AT ALL FOR MY LITTLE BANANA .
Thanks BMS!
