Now I understand. I thought you were complaining about the current BMW diesel designs, which are head and shoulders better than they ever were before in terms of power, responsiveness, economy, and emissions.

As far as gassers go, whats not to like about better power and economy that are available with turbocharged vehicles? It appears that all automakers who are concerned about both aspects have turned to turbocharging. This indicates that they've gone as far as they can with injection systems and variable valve timing. Turbocharging is the most practical means available to them for mass produced vehicles.
