As in the old days, AMGs are soon to be sold without the AMG kits, Quad Pipes etc:
To look more like a regular E-Class
The 2014 Mercedes-Benz E63 AMG will soon be offered with a Business Line option which will be available through AMG's Performance Studio.
AMG's CEO Ola Källenius has given an interview to Car & Driver in which he offered some details about the upcoming Business Line package for the 2014 E63 AMG. It will be available only in Europe and will be offered through AMG's Performance Studio.
This package will tone down the aggressive looks of the E63 AMG and make it look more like a regular E-Class, turning it into a "sleeper car". One of the most important changes will be the removal of the quad exhaust setup of the AMG version.
All modifications will be in the aesthetics of the car as they won't involve a performance downgrade. This means the E63 AMG Business Line will retain its twin-turbo V8 5.5-liter engine producing 557 HP (410 kW) and 531 lb-ft (720 Nm) of torque.
The reason why it won't be offered in the United States is because the desire for adopting a more stock appearance for a flagship model is an "almost exclusively German phenomenon."
