Driving a Mercedes means driving a piece of German engineering at its finest. Every model, from the compact A-Class to the flagship S-Class, is designed with precision and sophistication. But even excellence can be refined. At Auto Upgrades, we apply OEM-level calibration methods to take your Mercedes further—more power, more torque, sharper response—without sacrificing the smooth refinement and reliability that define the brand.

From daily drivers to performance icons, we tune the full Mercedes-Benz lineup with the same engineering discipline. AMG models, in particular, respond exceptionally well to precise recalibration, combining brutal acceleration with the composure you expect from Stuttgart.
