The reality from BMW is simply this.....based on their own words from their own magazine......"the current generation boxer is as evolved as it could be, it will not see another revision. A new water-air cooled boxer is being developed/tested to meet Euro 3 and eventually Euro 5 smog certification."
I say debate all you want, but let the reality set in!
A new engine sounds good to me but the current engine thats been paid for sounds better!!
Still, I'll love seeming the engineering behind the new motor along with appreciating the simplicity of where things started.
