Mercedez Benz News Mercedes-AMG Going AWD for All

Recommended Posts

Mercedes-AMG says that it will be moving to an all all-wheel drive lineup in the near future and engine downsizing as Mercedes moves towards an all electrified lineup.

Autocar spoke to AMG boss Tobia Moers who said "Customers have given us the answer, and most want four-wheel drive. Back in the days when we had an AMG E-Class as rear-wheel drive and with four-wheel drive as an option, over 90% chose four-wheel drive."

Even the AMG's flagship, the AMG GT  will move to all-wheel drive in the near future.  The current E63 AMG has an all-wheel drive system that uses clutches to send 100% of torque to whichever axle needs it, including a drift mode that will completely disengages the front axle if requested by the driver.

4Matic+ is the way to go.  You need grip to put the power down.  Makes sense to make it standard.

      Rumor has it that the next AMG C63 will be the first of a number of models to ditch their V8 in favor of 4-cylinder hybrid power. According to Autocar, the C63 could also lose a rear-wheel drive option, going instead with standard all-wheel drive. 
      The engine would be an electrified version of the new M139 turbocharged 2.0-liter.  In it's most powerful current form, it is the most powerful 4-cylinder in production anywhere putting out 416 horsepower and 369 lb-ft of torque, and that's without any electric boosting.  The engine was engineered to be mounted transversely or longitudinally and also with an eye on hybridization.
      For the C63, the M139 engine would adopt a 48 volt starter motor similar to the one used in the CLS 53 4Matic.  On that car, the motor provides an additional 22 hp and 184 lb-ft of torque, however in the C63, it would be tuned for even more power to reach up to a total system horsepower over 500. 
      One main advantage to this setup would be a significant reduction in weight over the front axle.  Additionally, the engine/motor combination has a lower center of gravity, that would be expected to improve handling and control. 
      Moving the C63 to a hybrid powertrain is consistent with Mercedes' desire to reduce fleet CO2 emissions.

      Back on June 7th, Mercedes-AMG unveiled their newest 4-cylinder engine, and their most powerful.  Producing 416 horsepower and 369 lb.-ft of torque in the S Version, it is currently the most powerful 4-cylinder engine currently in production.  AMG is also making a base version with 382 horsepower and 354 lb.-ft of torque, both in transverse applications. Initially, this engine will debut in the Mercede A45 S AMG and Mercedes CLA 45 S AMG.  According to AMG head, Tobias Moers, expect to see use of this engine expand to other product lines. 
      According the Moers, the engine was designed from the start to be able to be mounted as longitudinal engines.  So while it probably won't become a C45 or E45, it could become the standard engine in the C43 or E53.  It is also capable of accepting electrification making for an even more powerful option. 
      This strategy of combining a small displacement 4-cylinder with electrification could contribute to Mercedes' strategy of stopping development of new internal combustion engine families.

      Mercedes-AMG has unvieled their newest and most powerful 4-cylinder engine. Clocking in at 416 horsepower and 369 lb-ft of torque for the S version, it is the most powerful 4-cylinder engine currently in production.  There is also a "base" model of this engine that produces 382 HP and 354 lb-ft of torque.  Peak torque for the S Model is available from 5000 - 5250 rpm while the base version's torque peak comes in at 4,750 rpm and continues to 5,000 rpm. Mercedes says that putting the torque peak higher in the RPM band makes the engine more free revving. Maximum engine speed for both versions is 7,200 rpm. 
      The engine, while still transverse, is rotated 180 degrees to put the turbo in the back up against the firewall and the intake system is positioned up front to make for a lower design with fewer air restrictions.  The turbo itself is a twin-scroll unit and has roller bearings to reduce friction and quicken turbo response.  The engines are hand built by a single craftsman in Affalterbach Germany.  
      No word yet on which vehicles these engines will go in, but its a safe bet to look for them to show up in the Mercedes A-Class, CLA-Class, and probably the GLB-Class.
