I had no idea what he was talking about and he said that the vehicle was supposed to be programmed to act like a 2l engine based on the price he paid but he got 3l programming by mistake...he was very happy about the performance until he took it in for service and the techs noticed the mistake and changed it to the 2l programming. Apparently a common engine was used for a number of variants and software was used to change the performance to be appropriate for the particular "model" that was purchased, and that he was very disappointed to find that his car was less peppy AND got worse fuel mileage when he got it back with the undesired 2l programming (not sure it if was gas or diesel).
I told him that sounded pretty crazy and he agreed...I have honestly never heard of anything quite like that since and I am still not sure if he was just messing with me. Obviously there is lots of tuning through adjusting software and very similar engines can have somewhat different power performance numbers in different applications...I knew from some Italian friends that 2l was a major inflection point in taxation levels based on engine displacement in their country, but the idea of using a bigger engine and detuning it so much through software that it was legally considered to be a smaller engine really perplexed me.
Or, maybe it was a turbo with the boost being adjusted and the 2l/3l levels just represented equivalent performance somehow?
That guy was the best salesman I ever met, BTW, he came to that office prepared to make his sales pitch in German and switched to absolutely perfect English on the fly when he realized there were Americans visiting. His presentation was thorough and delivered flawlessly, plus he knew his products inside and out.
Companies do that all the time, BMW 420 and 428 share the same engine, the 428 has just a bigger intercooler. So is in the CPU world, your Intel I5 might of started its life like an I7, but had a core that was not performing up to specs, so it gets dumbed down and sold as an I5
