Are their any other bi-turbo cars? (Audis not included)

no you do understand, just the "twin" = identical, not so to speak "fraternal" lol...
girlguy, yeah yeah, matching before and after components should be used in a twin setup obviously
bi-twin, who cares..
as long as u understand smaller + larger inline's you are fine i assume

What contributes to different company's using different turbos?
Engine size must be considered I'm supposing. Beyond that, how are sizes/standards for turbos determined? I wouldn't think it is as simple as company preference.

I guess it's a terminology issue:
The term twin-turbo for me means the same as bi-turbo--maybe I'm wrong for that.
Maserati called their horrid little car a biturbo and Nissan called their 300ZX a twin-turbo; the turbo layouts were essentially the same (as far as I can tell).
I explicitly use the term "sequential" for cars that have staggered boost regimes (e.g., RX-7, 535d, Supra Turbo).

Whats the difference between "BI" and "TWIN" turbo;s?
To me, bi is the same thing as two (or twin), so I was always under the assumption the Germans didn't want to be like the Japs and called our setup Bi-turbo instead of twin turbo

Re: What contributes to different company's using different turbos?
I imagine that's what the R&D budget is for--extensive testing to determine the best fit.
I doubt BMW decided out of the blue to use Mitsubishi turbochargers for some of their cars when there are so many prominent German and European manufacturers.
How strong is the NA engine without boost? Is it responsive and torquey [sic] at low rpm (boost can come on later so perhaps a lazier turbocharger) or does it really need the turbocharger for all low rpm performance (quicker boost, thus smaller turbo or variable-vane geometry)? Etc. Etc.

They have a V12 TDI, too. It's absurd. (link inside)
