That's interesting to read, I've always thought AMG would keep the current 6.2L V8's but changing a few internals for turbocharging, never thought they would actually reduce the displacement for higher hp & tq.

well am guessing it has to do something with being a bit more fuel efficient and personally, I'll take a variable vein TWIN TURBO on a 5 liter or even a 4 liter. big bore is really nice but with what we're all going through right now, even if we say gas prices is nothing to AMG buyers, still it affects some. possibly also, the 6.2 lacks the low end torque compared to the old engine it replaced.

Its a simple situation. The 6.2L motor is very expensive to produce compared to the more conventional 5.5L NA motor seen in the non amg cars. In order to keep the cars competitive on price AMG went and worked with MB to produce a series of turbo motors for future production.

These turbo motors will replace the current high hp cars including the 600 (non amg) motors.

Its not a matter of gas prices being an issue for AMG customers its matter of MB having to meet cafe standards both here and in Europe. These 55k and 63 motors get terrible mpg and these new motors use direct injection to make them less of a disaster for meeting fuel efficiency standards.
