Up front the CLS now sports a version of the diamond radiator grille that was first seen on the A-Class. This is complemented by reworked front bumpers with enlarged and more overtly styled air intakes. At the rear the most significant change is the addition of vertical vents in the bumpers.
As revealed earlier this week, the facelifted CLS is the first model to sport the company's new Multibeam LED headlights. Each headlight unit consists of 24 LED clusters, each of which can be switched on and off or dimmed individually by the car's on-board computers.
By switching off individual clusters Multibeam can shield other road users from the car's high beam. As the Multibeam's dipped beam modules are capable of swivelling, the CLS is capable of constantly lighting up the road as you round a corner.
While other active headlight systems can only react to steering input, the Multibeam system is able to scan the road ahead using the car's camera and provide preview lighting before the driver has turned the wheel. Using data from the nav system Multibeam is able to provide additional directional lighting on roundabouts.
The biggest change to the CLS-Class' interior is a free-standing 8.0-inch high resolution display. To help speed up on-screen navigation there are now two extra menu buttons located next to the CLS' Comand controller.
Overseas, the turbo-diesel engine gains one new variant with the 125kW/400Nm CLS220 BlueTEC. This is complemented by the existing 150kW/500Nm CLS250 BlueTEC and 190kW/620Nm V6 CLS350 BlueTEC.
The CLS400 with its 245kW/480Nm 3.5-litre twin-turbo V6 joins the petrol motor line. This new variant sits under the 300kW/600Nm 4.6-litre V8 CLS500 in the non-AMG range.
A new nine-speed automatic, dubbed 9G-Tronic, is available on the CLS220 BlueTEC, CLS250 BlueTEC, CLS350 BlueTEC and CLS500. American and European buyers will be offered all-wheel drive on more variants than before.
Spearheading the revised range is a mechanically unchanged CLS63 AMG. In regular form CLS63's 5.5-litre twin-turbocharged V8 churns out 410kW of power and 720Nm of torque, while the S model has 430kW/800Nm on tap.
The updated CLS range will go on sale in Australia in the first quarter of 2015.
