I am looking to trade my ML 350 for a 2016 GLE 400. What is the difference between "twin turbos and bi turbos"?

No difference. The 2016 GLE400 uses the M276 3.0L V6 with two turbos, or biturbo, or twin turbo. The nomenclature is synonymous in this example.

Mercedes-Benz uses the marketing term "biturbo" on their website.

Thank you. A friend suggested bi turbo was a small one for low rpms and a larger one for higher rpms.

There is a difference if you want to be technical with the term.
Twin Turbo: 2 different size turbo chargers (Smaller Turbo for Low RPM and larger one for high RPM)
BiTurbo: are (2) same size turbochargers

I used to have a Nissan 300zx Twinturbo and the turbos were the same size.

Directly from Google: "The term twin turbo has been often given to vehicles that use sequential turbos, a small one for low rpm torque, and a larger one for higher rpms and power. The biturbo system uses two equally sized turbos."

mbusa.com on engine in GLE43AMG and GLE63AMG:

• Engine: AMG-enhanced 3.0L V6 biturbo or Handcrafted AMG 5.5L V8 biturbo

I always knew of twin turbo as a smaller and larger turbos sequentially, like on last generation of Supra TT Mk IV from the 90s. However, Nissan did cal its 90s 300ZX TwinTurbo instead of BiTurbo with parallel (same sized) turbos. Toyota used I6 and Nissan V6, hence maybe a naming difference.

Old thread sorry, but that sure is some backwards naming
