Mercedes-AMG has showcased the latest addition to its recently launched '53' line of mild hybrid performance cars with the new Mercedes-AMG E 53, available in sedan, coupe and convertible body styles. Replacing the earlier E 43, the most notable addition is the new 48-volt electrical system.

This system provides a host of benefits over a standard 12-volt layout. Called the EQ Boost starter-alternator, this electric auxiliary compressor builds up a high charge pressure, without any delay, for a faster increase in torque for acceleration until the large exhaust gas turbocharger is deployed. As a result, the 3.0-liter engine reacts spontaneously and provides lag-free responses.
Other advantages are that this system lets all electrical components run, like the power steering and air-conditioning, separate from the engine. This allows AMG to offer a coast mode to improve efficiency.

Other than this, the E 53 is powered by a 3.0-litre inline six-cylinder turbocharged engine that puts out 429PS and 520Nm. The EQ boost alternator adds an additional 21PS and 250Nm when required. The motor is paired with AMG's new nine-speed transmission. The car also comes with four-wheel drive and variable torque distribution, multi-chamber air suspension and continuously adjustable damping. The usual plethora of suspension, steering and engine modes are offered to tailor the experience to one's liking.

In terms of aesthetics, the E 53 follows a middle-ground between the standard E-Class and the full-bore E 63. The model is distinguishable by its new bulged bonnet, quad exhaust pipes separated by a subtle diffuser. The interiors too follow this trend. The E 53 gets the widescreen infotainment, AMG performance seats and wheel, and, carbon-fibre and aluminium trim.

The E 53 seems to have been placed at the sweet spot between the regular E-Class and the range-topping E 63. It should be ideal for buyers who find the E 63 a bit out of reach in terms of price and do not mind the performance cut, or for someone who will use the car in a more family-oriented setting. The Mercedes-AMG E 53 will launch in the US at the end of the year. It is not known if the car will make it to India but given that the E 63 S has just been launched and the  '43' line of AMGs have been sold here, chances are high.
