E430 has a little bit more torque on the low band,
and burns little less fuel. Apart from that, they
even sound the same. I drive E50 and had numerous
chances to compare it against E55 which differs to
E50 in same way as E420 to E430 (M119 vs. M113 engine). The latter has two spark plugs per
cyllinder and bit improved electronics, intake
subsystem and..thats about it.
Difference in performance is really slight, and
as for my E50 to E55 - not noticeable at all.
But as with all newer models, with 430 you have
increased chances of getting better equiped car
ie. ESP is rare option for E420, i think that
all 430s come with ESP as standard.
I accidentally posted this on the E50/E55 AMG forum.
Anyway, what is the difference between these two engines would you say? How about performance characteristics? Would you say the E430 is faster, or about the same as the E420?
I drove a '98 E320 and a '97 E320 back-tot-back once before. Both cars were very much the same in power, except the inline-six seemed a little louder at speed.
