Mercedes just announced 2017 E43 AMG with 396 HP. Extra 34 HP than the C43 AMG and GLE 43 AMG (current C450 AMG and GLE 450 AMG), According to CAR Scoops and CAR & DRIVER. E43 has bigger turbo and different software to pump out that extra HP. I truly hope Mercedes doesn't put that in the GLE 43 Coupe when the time comes to change the name. I will be pissed!!!!!
