I still cant understand why mercedes took such a step backwards with their engines. I dont care what they say about meeting emission standards. They are probably the only car company who sells luxury cars that doesnt have variable valve timing. I mean even some budget cars have variable timing. They could have cut down on emissions just as well keeping VVT.
Also twin spark SOHC seems like a huge step backwards from DOHC as witnessed by the fact that they are now moving back to acoustically sound DOHC engines vs. the tractor engines that we have now.
Weird isnt it?
