Chi parla non e' il solito scribacchino ma : Autodelta’s head of Research & Development, Sergio Truzzi, ....
"Truzzi adds, “Our initial bench-testing of the new Alfa Romeo V6 unit showed that the manufacturer-quoted horsepower figures at the flywheel (260bhp) were very accurate, but in a road-use scenario the car doesn’t feel as if it hasn’t quite the power one would expect. The rolling road tests showed that the V6 engine (in the Brera) is draining 35 percent of that power through the new Torsen C-System four-wheel-drive arrangement. There is little we can do to channel any of this into extra power at the road wheels, and it is something we have to take into account and work around. With an extra 80-100bhp, channelled through all four wheels, we can turn the 3.2 Brera into a very potent sportscar. The new engine certainly has the ability to deliver, and the benchmark chassis has been designed to be able to push performance significantly forward.”

( Draining= perdere, prosciugare .... ) il motore V6 perde il 35% di pontenza attraverso il Torsen C-System four-wheel-drive, quindi hanno pensato di aggiungere la stessa potenza (88 CV) persa per ritornare alle prestazioni ideali ....
COME e' possibile perdere il 35 % ?: sulla crosswagon (con una TI molto simile se non uguale ) la perdita era sensibile ma molto inferiore !!
Se e' vero, come e' possiible che altre case promettano dati migliori in accellerazione con una TI (con schema piu' semplice) rispetto al modello con 2 ruote motrici ?
