The Mercedes E63 AMG prides itself in blending performance with luxury. That seamless combination has allowed the luxury saloon to carve a niche for itself in the market, but German tuner Loewenstein Manufaktur isn’t impressed with just a standard E63 AMG; it wants to turn it into a powerhouse. That should always the formula for any aftermarket company that plans to succeed in the realm of making fast cars faster.

You won’t see any frills on this program. None of those unnecessary dress ups and none of those fancy paint colors. What you see is what you get, until you pop open the hood and see where the magic happens. I’m not going to divulge the details of the engine upgrade just yet, but I will tell you that it’s impressive enough to give the E63 AMG the juice it needs to compete with a lot of supercars today.

Not bad for a cushy luxo-sedan.

It doesn’t deviate from its standard looks, but this Mercedes E63 AMG has enough power to make supercars tremble in fear. Props to Loewenstein for giving this luxury saloon on hell of a knockout punch.

In addition to the massive engine upgrade, Loewenstein also dropped the car’s height by 25 mm (0.98 inch), thanks to the newly installed threaded springs on the front axle, as well as a mechanical adaptation of the serial airmatic system to the rear axle. Also included is a set of 20-inch RENNSPORT wheels Loeweinstein wrapped in Michelin Super Sport tires.

Under the hood is where all the goodness really lies. Despite AMG reducing the E63 AMG’s engine capacity from 6.3 liters to just 5.5 liters, this powerful sedan still produces 525 horsepower (575 horsepower with the "Performance Pack"). With this odd decrease in capacity but increase in horsepower, Loewenstein knew it was working with an engine that was already working overtime to produce its ponies.

With this, Loewenstein chose to add new sports catalyzers and a sports air filter to the mix, and reprogram the car’s ECU system. With these items in place, the E63 AMG now produces a mouth-watering 720 horsepower and 774 pound-feet of torque, which is around the same numbers the Lamborghini Aventador produces.

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read More

Press Release

The testers of the industrial magazine AutoBild used to have just one word for the engine of the Mercedes-Benz E63 AMG: “Aweeesome”! The truth though is that the initial disgust was immense when AMG disclosed that it was reducing the cubic capacity of the eight-cylinder engine from 6.3 to just 5.5. The adoption of double turbo power however enhanced the maximum performance of 525 horse power and even 575 horse power with the “Performance package”. Equally new and unusual for a sports limousine of this category: the automatic start/stop system, which switches off the engine when the traffic light turns red. On paper, this is expected to facilitate the reduction of fuel consumption to less than 10 liters for every 100 km.

Rather unusual for a tuner: The Loewenstein Manufaktur from Wuppertal completely abandons the aerodynamic frippery in its E-LM63-700 and concentrates completely on the continued development of performance. In the process, it should have been assumed though that 525 or 575 horse power and the AMG-typical perfectly balanced chassis will leave almost nothing to be desired. Yet Loewenstein made a choice: Engine and chassis can easily stomach more than 700 horse power. All said and done: Thanks to the comprehensive reprogramming of the electronic control unit of the engine and the installation of special sports catalyzers and a sports air filter of the company K&N, unbelievable 720 horse power and a maximum torque of 1,050 Nm now drag the drive shafts.

The fact that a power potential of this magnitude vehemently pushes the E-class that has been refined by Loewenstein is simply a matter-of-course. Particularly astounding is also the ease with which the 720 horse power is controlled. Always present as an acoustic back-up: the rattling and bubbling of the eight-cylinder biturbo, which however never acts pervasively but actually serves to always put a satisfactory smile on faces. The Loewenstein modifications on the AMG chassis are limited to the lowering by 25 millimeters through the threaded springs on the front axle as well as a mechanical adaptation of the serial airmatic system to the rear axle.
The new wheel/tire combination ensures a powerful grip and lateral dynamics: the company’s own 3-part RENNSPORT wheel was installed in the front in 8.5 and in the rear, in 10.5x20 inches. The rims are covered in Michelin Super Sport-tires of the format 255/30R20 on the steering axle and 295/25ZR20 on the drive axle.

The singular visual reworking of the E-LM63-700 pictured here, is its complete wrapping in a ground aluminum look whose rough surface is a real eye-catcher.
