L Luxury cars belong to Wilshire-Beverly-Hills- Hotel like the luxury shops across the street. Nobel cars line up here every day. Mostly black, white or silver, rarely red. For this reason alone, the Mercedes CLS 63 AMG is an absolute eye-catcher.

Ola Källenius, the new AMG boss, and head of development Tobias Mörs have arranged to meet for the last test drive with the Mercedes CLS 63 AMG. It goes over the fine boulevards in Beverly Hills, over highways, over winding streets up into the mountains and back to the coast to Santa Monica.

Mercedes CLS AMG can also be armed

According to Källenius, the new Mercedes CLS 63 AMG should prove one thing above all: “That it can cruise.” The new AMG can also show its evil side on short intermediate sprints in the mountains. Then Källenius “armed” the Mercedes CLS 63 AMG: engine-gearbox switch to “Sport Plus”, which reduced the switching time to the blink of an eye. The dampers of the Mercedes CLS 63 AMG can also be adjusted in three stages for the changeover curves. And the AMG boss, who formerly headed the Mercedes Formula 1 offshoot Performance Engines in Brixworth, speaks from experience when he reveals: 'For the Nürburgring-Nordschleife you shouldn't choose more than level two.'

If you want, you can also deactivate the ESP in two stages in the Mercedes CLS 63 AMG: With 'ESP Sport' you can conjure up decent lap times even on racetracks. 'ESP off' is something for experts on the valance. Because with it, proper drifts are possible. But even then the electronic lifeline is not completely deactivated, but only in a kind of watchful mode. Tobias Mörs reassured: “Normally you can't get within the control range even at racing speed on the Nordschleife.” The electronic guardian angel can only be activated if you brake really brutally or drive the wheel extremely badly.

Mercedes CLS 63 AMG can cruisers and Being a sports car

The Mercedes CLS 63 AMG has two sides. In Beverly Hills he gives the tame cruiser. It is tuned to be sporty, but it is not annoying with unnecessary hardness. If you choose transmission level C (Controlled Efficiency), you start in second gear, activate the start-stop program for the traffic light breaks - and could complete the New European Driving Cycle with a consumption of just 9.9 liters per 100 kilometers.

About the Nürburgring you canbut also beat the four-door Mercedes CLS 63 AMG Coupé in just under eight minutes and ten seconds - with the standard tires, of course, the Conti Sport Contact 5. In S mode, the supercharged eight-cylinder emits such a rich engine sound, as you actually only know from large naturally aspirated engines. Shifting takes place with crisp double-throttle thrusts, and if you take off the gas, the finely tuned sound system lapses into a pleasant bubbling.

Testing the Mercedes CLS 63 AMG on the Nordschleife

The chassis of the Mercedes CLS 63 AMG has steel springs at the front and air suspension with automatic level control at the rear. The front axle is 24 millimeters wider than the series. And the electromechanical steering not only saves 0.3 liters in the consumption cycle, but also offers the right power assistance in all speed ranges, depending on the chassis mode. 'First of all, the elastokinematics are important for the correct steering characteristics,' reveals Mörs, who has reworked the entire chassis and the elastic elements of the wheel suspensions to meet AMG requirements.

With a rough layout, it was first on the test track to Papenburg, then to the Nürburgring. 'Two laps on the Nordschleife, then on the Eifel country roads, then you know everything about a chassis,' explains the expert. The fact that 15,000 to 20,000 kilometers were still required for the pure chassis tuning is also due to the fine-tuning of the different ESP levels. Overall, the Mercedes CLS 63 AMG made it a kilometer millionaire in its development. 500,000 kilometers alone were accumulated in endurance runs. These are a special stress program at AMG, after all, it goes up to 300 km /h.

Performance package in the CLS 63 AMG for extra horsepower

The normal Mercedes CLS 63 AMG is indeed electronically braked at 250 km /h, but if you choose the so-called performance package, you get the boost pressure increased from one to 1.3 bar. Instead of 525 HP, there is a full 557 HP. The AMG Driver’s Package can be added to this: For the Mercedes CLS 63 AMG, it includes raising the top speed to 300 km /h and for the driver participating in a driver training course at the AMG Driving Academy.

While the high-speed tests may be a challenge for the Mercedes CLS 63 AMG drive, the 10,000 kilometers driven on the Nürburgring-Nordschleife are an ordeal that every new AMG model has to pass before series production. The last test kilometers on Beverly Hills Boulevard are a rather relaxed exercise, even if Tobias Mörs made some notes. All points that he would like to work through before the start of series production.
