Almost three years after its debut at the 2006 Paris Show and Mercedes is readying a subtle mid-life facelift for the CL-Class that may be re-designated as the S-Coupe when the car arrives at Merc's showrooms sometime during the first quarter of 2010. Our spies captured the range-topping AMG version of the CL that will once again be available in two guises, the V8-powered CL63 AMG and the V12-powered CL65 AMG or, S63 and S65 AMG Coupe respectively if Mercedes decides to change the coupe's name as it did with the CLK's replacement, the E-Class Coupe.
Like the recently updated S63 and S65 AMG sedans, while the CL63 and C65 AMG coupes won't have more muscle than before, they will boast slightly improved fuel economy and decreased CO2 emission figures thanks to the retuning of their engine management systems.
As with the rest of the range, the AMG variants will benefit from a mildly redesigned nose complete with a more pointed front grille and a new bumper incorporating a pair of LED daytime running lights. Though the test mule seen in these spy photos featured the same bodykit with the current CL AMGs, expect to see new side skirts and a different rear diffuser plus restyled alloy wheels.
With the exception of the Mercedes' new split view central monitor that allows the passenger and driver to see different pictures on the same screen and quite possibly, new trim options, the interior of the refreshed CL will remain untouched.
This means that the CL63 AMG's 6.3-litre V8 will make 525-horsepower and a maximum torque of 630Nm or 465 lb/ft while the CL65 AMG's 6.0-litre bi-turbocharged V12 will deliver an output of 612HP and 1000Nm or 737 lb/ft of torque.
Aside from the engine management updates, AMG engineers are also expected to tweak the coupes' Active Body Control air suspension and braking systems.
