Sounds promising. I have no doubt that ///M will not disappoint. I am a bit worried about the next generation M5 engine though. I'm just not seeing where ///M can go next with engines. They are definitely not going to go with a bespoke engine as it would be too costly and go against the current business model of efficiency of shared parts with non-M engines. We'll start seeing more stuff in about 2 to 3 years about the next M5. The next generation 5-Series should be out in 2016 as a 2017 model year. So only a couple of more years away.
