Welcome to MY2011 and welcome to the brand new facelifted versions of the Mercedes CL63 AMG and CL65 AMG. This year, Mercedes has opted to leave the exterior of their luxury coupe alone for the most part and focus their attention on the engines of these two vehicles. Nothing shouts perfection like an increase in horsepower andMercedes wants to make this perfectly clear with these two models by using direct gasoline injection, twin turbochargers, air/water cooling, and controlled efficiency stop/start function.
Starting with the CL63AMG , Mercedes has thrown out the use of the naturally aspirated 6.2L AMG V8 engine and opted instead for a 5.5L biturbo engine mated to an AMG speedshift MCT 7-speed sports transmission with Sport, Comfort, and Manual modes. This exchange has allowed for an 18hp and 125lb-ft of torque increase for the 2011 model. This little kitten now purrs with 563hp and 664lb-ft of torque. Want to make it go even faster? Opt for the AMG Performance package and the Mercedes turns into a tiger with 563hp and 664lb-ft of torque. The standard model makes the 0-60mph sprint in 4.4secs and has a top speed electronically limited to 155mph while the AMG Performance package shaves 0.1secs off of the 0-60mph sprint and increases top speed to 186mph. Even though the 2011 Mercedes CL63 AMG has had an incredible boost in power, Mercedes has managed to decrease fuel consumption by 27% and CO2 emissions by 30.
The 2011 Mercedes CL65 AMG carries over the same 6.0L twin turbo V12 engine as last year for its range topper, but Mercedes has managed to push out an extra 17hp to the car’s performance. Now the CL65 AMG is capable of producing 621hp at 4800RPM and 738lb-ft of torque at 2000-4000RPM. The engine is mated to an AMG speedshift 5-spped transmission with Sport, Comfort, and Manual modes. This combination allows the CL65 AMG to make the 0-60mph sprint in 4.2secs and leaves it with an electronically limited top speed of 186mph.
