Most manufacturers are coming up with various different ways to go green. Mercedes AMG is also on the same path. The G65, with a 6.0-litre V12 engine, that produces 630bhp and 1000 Nm of torque is clearly not the most fuel-efficient. As the risk of slowly becoming socially unacceptable to own such a monstrous vehicle in many environmentally concerned societies, the iconic vehicle which is also one of the longest-running models of Mercedes will soon receive a smaller 2.0-litre engine. This is estimated to produce around 300bhp and 400 Nm of torque.The models having the new engines will significantly reduce fuel consumptions and therefore, CO2 emissions. The prices are also likely to be much cheaper than the existing models too. The other apart from that is the lower taxes and import barriers in certain countries, like China for instance. The company plans to take advantage of these benefits and tap newer markets.
