I've come across some interesting discussions on various forums about how the S65 stacks up to the S62 4.9L V8 (E39-M5 & E52 Z8). We all know that the E39 M5 was considered a game changer in its time for sports sedans, relatively high revving V8 400hp @ 6600 with 7k redline and decent torque, 369 lb/ft @ 3800 rpm. As we know the 4.0L S65 puts out 414 hp @ 8300 rpm and 295 lb/ft @ 3900 rpm. It appears that some of the e39 boys feel the S65 is a let down performance wise due to the torque deficit and "slow" rev characteristics
, albeit the real world performance specs show the E9X's ///M3(s) to be faster, the overall delivery of the S62 being preferred by "them" due to the torque output of the S62. On the other hand it's also been stated that the S62 wasn't a "true" ///M engine as it wasn't significantly different from 540i/740i M62 V8. But some say the S62 is more reliable. What's the consensus here?
BTW: I did a search and didn't see any threads in this section that put the two engines head to head.
