AMG models typically have more aggressive looks, a higher level of performance, better handling and stability, and more extensive use of carbon fiber than their regular Mercedes counterparts. AMG models are typically the most expensive and highest-performance of each Mercedes class, with the exception of non-AMG V12 models found in the most expensive nameplates of the lineup.
Verily, it is a 5.5-liter, twin-turbo V8, superseding the none-too-shabby
6.3-liter naturally aspirated eight that doth make 518 hp and 465 lb-ft of torque.
The new block on the aluminium block kicks out 536 hp and 590 lb-ft,
while reducing fuel consumption by up to 25 percent.
This is achieved with the help of direct gasoline injection.
M157 this engine will be coupled to a 7G-TRONIC AMG SPEED SHIFT PLUS transmission
that offers automatic and driver-operated gearshifts.
There’s also a Performance Package available to bulge output to 563 hp and 664 lb-ft.
The M113 supercharged 5.4 L V8 engine was mated to the Speedshift 5-speed automatic transmission,
which has a torque capacity of 796 lb·ft (1,079 N·m), as the newer 7G-Tronic introduced in 2003 is limited to 542 lb·ft (735 N·m), not enough to handle the torque from the supercharged V8.
Assembling and the tuneup are AMG, but the basis is Mercedes-Benz.
