Something else to ponder: Why does it seem the IS-F is so much faster than the E39 M5, a car which it is very similar in weight, power and torque (and not TOO far off in redline and final drive either)? I wonder what C&D's test numbers were for the old M5? Because just looking at these early tests, if you lined them up, the M5 will get killed.
Either the IS-F is underrated, or that is one very amazing transmission. Or both.
Either way, Kudos to Lexus for taking us all by surprise - at least in the straight line department. It will be very interesting to see the comparo tests vs. an E90 M3.
A gen-u-ine BMW eff-eight-zero with them tandem clutches in the transmission and that dad gum sun roof on the top-a da cawr.
