Biturbo 12-cylinder engine

The Maybach V12 is a petrol engine with a cylinder angle of 60°. It is available in two different displacements and power variants for your Maybach.
Biturbo 12-cylinder engine
The cylinder angle of 60° is ideally suited to the vibration characteristics of a V12 petrol engine. The engine is designed for low wear, economical operation, high levels of comfort and smoothness, as well as impressive power delivery.
The engine design is characterised by three valves per cylinder, initialised dual ignition, a rigid aluminium crankcase in lightweight design and a crankshaft with grey cast-iron inserts in the main bearings. Two turbochargers with waste gate control at the cylinder banks ensure outstanding responsiveness combined with maximum torque delivery already at low engine speeds.
With the Maybach facelift 2010, all the impressively powerful engines run with lower fuel consumption and CO2 emissions, thanks to new control and diagnostic sensors per exhaust tract and the optimised engine control unit software.
In addition to the reduced fuel consumption and emissions, the engines of the Maybach 57 S and the Maybach 62 S improved their rated output power and acceleration values. This could be realised by using new turbochargers with larger impellers. In line with the Maybach approach, those special twelve-cylinder biturbo engines are 
hand-assembled by AMG. A single technician is responsible for his assigned engine and puts his signature on the characteristic model plate, which is attached to the cover of the V12 biturbo; a guarantee of the greatest care and highest quality.
Since the 2010 facelit, Maybach's leading position in the high-end luxury segment has been not only extended regarding rated output; Maybach could also set a new benchmark concerning fuel consumption and CO2 emissions.
Fuel consumption (combined) 15,8-15,0 l/100 km, CO2 emissions (combined) 368-350 g/km.
The figures do not express any description of the emissions or fuel consumption of a car, are not part of any offer and are intended to compare types of vehicles only.
5-speed automatic transmission

5-speed automatic transmission

The in-house made 5-speed automatic transmission has 2 shift programs and takes into account a series of driving dynamics parameters as well as the individual driving style when selecting the gears.
In addition, this transmission features a torque converter lockup clutch, which can also be engaged in the lower partial load and speed range. Rapid adaptation of the transmission to the prevailing situation is made possible by continuous electronic comparison of different influencing factors such as rolling resistance (load, gradient) or driver reactions (accelerator movement, frequency of manual gearshifts, the vehicle's longitudinal or lateral acceleration). 

A program selector button allows the driver to choose between the "S" (Standard) and "C" (Comfort) shift programs. For better control when starting, "C" mode features second-gear start and a higher reverse gear. 

Further features include a mechanical lock which prevents the vehicle from rolling away when the selector lever is in position "P", as well as a preventive measure against unauthorised operation of the selector lever.
