Loewenstein Shoots for Performance with the E-LM63-700

Loewenstein E-LM63-700

Bidding farewell to the 6.2-liter V-8 and welcoming a newcomer.

The 6.2-liter V-8 AMG engine known as the M156 made its presence known both audibly and in the seat of your pants when the throttle was pushed. It’s lovely naturally-aspirated note and heart-pounding power was intoxicating. Then Mercedes-Benz decided to downsize and add in a pair of turbochargers and the new M157 twin-turbocharged 5.5-liter AMG V-8 was born, and replaced the 6.2-liter. It was hard to say goodbye, until the sheer force of the new 5.5-liter V-8 was felt. The team at Loewenstein was disappointed with the change at first, then embraced it when they started to unlock to full potential of the 5.5-liter with their new E-LM63-700 Mercedes-Benz E 63 AMG.

The Mercedes-Benz E 63 AMG roars with either 525 or 575 horsepower depending on the options from the factory with its 5.5-liter, twin-turbocharged V-8 engine. Loewenstein Manufaktur took advantage of the two snails feeding boost pressure and completely optimized the engine electronics while adding a K&N sports air filter system and exhaust system with sports catalytic converters. When all was said and done, the mid-500 horsepower output grew to an astonishing 720 horsepower and 774 lb-ft. of torque – numbers not possible without the addition of forced induction with the 6.2-liter predecessor.

The team at Loewenstein Manufaktur knew that the chassis and drivetrain could handle over 700 horsepower, but they still decided to upgrade the wheels and suspension to add in a bit more grip for better control. A set of the company’s three-piece Rennsport wheel was installed on the E-LM63-700 in a wide 8.5 x 20 front and 10.5 x 20 rear setup with Michelin Super Sport tires measuring 255/30 R20 up front and 295/25 ZR20 at the rear to help rein in all 720 ponies. Aiding in the handling department are new threaded springs up front and a mechanical adaptation to the factory airmatic suspension at the rear to lower the overall ride height by 25 mm.

Loewenstein didn’t exactly go all-out with aerodynamics on the E-LM63-700. Instead, they just added on a subtle rear trunk spoiler lip and give the entire exterior a ground aluminum-look wrap with an almost satin finish. The finishing touch is a new set of black stripes to emphasize the character lines running the length of the super sedan.

All of the upgrades featured on the Loewenstein E-LM63-700 are currently available as a complete package or individually for all of the Mercedes-Benz E 63 AMG models with the 5.5-liter, twin-turbocharged V-8 engine.
