Background
The flagship four-door performance model in Mercedes-Benz range at the time of launch, the first-generation CLS 63 AMG was based upon the underpinnings of the W211 E-Class (as were the rest of the CLS models) but was heavily fettled, tuned and upgraded by AMG.
Arguably, the biggest selling point of the CLS 63 was the naturally-aspirated V8 engine at the heart of the car. Designated the M156, it produced 507bhp and 465 lb-ft of torque from the factory, enough to humble cars worth two or three times the CLS’ price tag, yet return impressive economy on a long run, thanks to the seven-speed Speedshift Plus transmission, which was also introduced with the model.
Underneath, AMG fitted a re-calibrated version of AMG’s Airmatic system, whilst 14.2” vented and drilled front rotors, along with 13” rear rotors with four-pot calipers help keep everything in check.
At the time of launch, the car was critically acclaimed by the motoring press, with the likes of Car and Driver in the states and Autocar in the UK singing its praises. Even CAR Magazine were quick to lavish this V8-powered brute with praise, stating “The AMG designed and built 6.2-litre V8 is automotive magnificence… It feels and sounds awe-inspiring – accelerative shock swiftly stuns your passengers into total quiet.”
Now, these naturally-aspirated V8s are only becoming more desirable. As the likes of mild-hybrid drivetrains and impending electrification seep further and further into the automotive world, why not give one last hurrah to the wonders of burning dead dinosaur juice, with arguably one of the best and most sonorous V8 engines to ever be made?
