Here's another awesome power upgrade for an already awesomely powerful car. This time it's crafty German tuning house Loewenstein that has taken a pre-facelift Mercedes E63 AMG and made it more powerful than the facelifted E63 AMG S-Model. While that super sedan boasts 585 hp and 590 lb-ft, the Loewenstein-tuned E63 has seen its 5.5-liter twin-turbo V8 boosted to a monstrous 720 hp and 774 lb-ft.

The E-LM63-700 upgrade kit includes a remapped ECU, specially-developed sports catalyzers, and a K&N sports air filter. Further upgrades include a custom suspension that drops the E63 by 25 mmm, while exterior mods include a set of 20-inch alloys and a ground aluminum body wrap.
