They certainly haven’t been a secret, but Mercedes-AMG has officially revealed its 53 series vehicles. The all-new CLS53 and E53 Coupe and Cabriolet models are sporting a new electrified six-cylinder engine, sending AMG into a whole new territory.
The basis of the three new models is Mercedes’ 3.0-liter inline-six under the hood. While this engine is already leveraged in other products, including the recently-announced CLS, this one has some extra boost. AMG has strapped both a conventional turbocharger and an electric compressor to this engine for added power. Meanwhile, EQ Boost will ease the burden on the gas engine to allow for extra fuel economy along with the added power.
At the core of this system is a new 48-volt electrical architecture necessary for the EQ Boost system. AMG says the combination of a conventional turbocharger and the EQ Boost system means there is absolutely no turbo lag because the car is benefiting from the instantaneous torque of the electric boost system just prior to the convention turbo spooling up.
The total system output is resting at 429 horsepower and 384 pound-feet of torque. The EQ Boost system is adding 21 horsepower and 184 pound-feet of torque to the three cars.
On all three cars the torque is sent to all four wheels via an AMG’s 4MATIC+ all-wheel drive system and nine-speed automatic transmission. More agility, neutral cornering performance and greater traction come courtesy of the AMG RIDE CONTROL+ air suspension developed in Affalterbach. The multi-chamber air suspension with particularly sporty spring/damper set-up and continuously adjustable damping ADS+ (Adaptive Damping System) combines outstanding driving dynamics with high ride comfort. A harder spring rate, for example when cornering and braking, effectively reduces body roll.
AMG says the cars will sprint from zero to 60 mph in about 4.4 seconds.
As with all series of AMG products, the new 53 cars have a unique appearance. All 53 cars will be identified by their twin-blade grille design that is unique from the 43 and similar to the 63 series cars. Additional changes have occurred to the front and rear fascias to better identify these three AMG models.
Inside AMG is debuting a new take on the AMG steering wheel, which includes several different trim options for buyers to select from. Unique seat designs and carbon fiber trim also add to the 53 series flare.
Mercedes-AMG says to expect the CLS53, E53 Coupe and E53 Cabriolet to go on sale in the U.S. later in 2018.
