Twin turbo or not on these?

[kolobos]

Two people I know have recently purchased the following:

E350 CDI 2012 Sport
C250 CDI 2011 AMG

Both say their cars are twin turbo although I cant find the details for either indicating they are twin turbo? Mercedes apparently didn't make an E350 v6 Twin during these years so I am a little confused. Any help appreciated as I am looking at getting an E350 AMG Sport in a couple of years from now.

The engine code for the 250 is OM651. Its a Twin turbo in 250 form.

E350 CDI 2012 Sport - single
C250 CDI 2011 AMG - twin

Just for your information, the OM651 remap rather nicely! My 2011 S212 gave another 36bhp and 60ft/lbs taking it to 240bhp and 400ft/lbs of torque

Thanks for your replies guys, however is the E350 CDI AMG Sport a twin or single? Thanks developer for your comments.

E350 should be a single turbo with variable geometry intake...

The twin turbos arent really two proper turbos. One is your main turbo and one is much smaller, designed to get rid of turbo lag I believe.
I like them because they are reliable, we see very few issues with them.
