How much does the 5.5 V12 bi-turbo take?
It is a twin-turbocharged V12 with substantial headroom. It responds strongly to a map, though we always work within what the drivetrain handles safely.
Why so many speed limiter removals?
These cars carry an electronic cut set at 250 km/h. Note that legal speed limits on public roads are unchanged by any electronic work.
How does this differ from the CL and CL63 entries?
This covers the 600 version specifically. Our history records the model under several designations, so check the others too.
