The upcoming 2018 Mercedes-AMG CLS53 4Matic+ has been teased on social media ahead of its reveal at the Detroit motor show this week.
In a short clip released on the company's Facebook page, we get a quick look at the new AMG model, partially revealing the alloy wheels, body kit and AMG add-ons that will distinguish the CLS53 from its more pedestrian siblings.
Key cues include AMG badging, large front brakes, and what appears to be a set of circular quad tailpipes at the rear.
It's believed the AMG CLS53 will draw upon an uprated version of the mild-hybrid powertrain used in the CLS450 – combining a turbocharged 3.0-litre straight six with a 48V on-board electric system.
The petrol motor puts out 270kW and 500Nm, while the electric assistance provides a boost of 16kW and 250Nm over "short periods".
We'd expect the AMG version to have slightly beefier outputs, which should drop the 0-100km/h claim from the CLS450's 4.8 seconds to under the 4.5-second mark.
It should be relatively efficient, too. According to the text during the clip, the CLS53 claims to use just 8.4L/100km on the combined cycle.
