This here is the all-new Mercedes-Benz S-Class-based Brabus SV12 R Biturbo 800. With 800 hp (597 kW) and 1,047 lb-ft (1,420 Nm) on tap, the R800 sets a new milestone in the luxury segment, while dwarfing the S65 AMG in the process.
This luxo-barge-on-steroids uses the same V12 engine that originally came with the BRABUS E V12. That means that the displacement has been increased from 5.5 to 6.3 liters (336 to 385 cui), by using a special crankshaft with longer stroke, larger pistons and corresponding larger bore.
A new air intake is also used, alongside high-performance manifolds and water-to-air intercoolers.
