GL550 Overview

The Mercedes GL550 is a full-size luxury SUV that offers excellent comfort as well as exceptional performance. Most of these models come from the USA, specifically the Mercedes manufacturing plant in Alabama. Since it’s very first year of inception, 2006, the GL550 has been put through a multitude of different tests and environments to better equip future models. Today, we have a reliable vehicle with a lot of potential under the hood if desired by the driver! Read on to learn more about our process of tuning the GL550 to help it realize its full potential! Another blog post by us details a GL450 tune as well!

Stock Mercedes GL550 Specs

The Mercedes GL550 has a M278 engine that we have mentioned in previous posts on our site. Like we mentioned before, we realized the M278’s potential right away! The M278 is a V8 Twin Turbo Charged Engine. The engine model before it, the M273, was naturally aspirated, the M278 features twin turbochargers, one per cylinder bank and gasoline direct injection with multi spark ignition. The M278 engine is much more fuel efficient that the M273 engine it replaces. The M278 engine for the GL550 has a horsepower right at 429, while the torque is at 516. These figures are respectable for a stock SUV of this size.

Something to note about this Mercedes is its length. Mercedes upsized the GL-class slightly for 2013 and beyond, increasing the length to 202.6 inches from 200.7, width to 78.0 from 75.4, and height to 72.8 from 72.4. Car and Driver also made a great point about why this Mercedes is unlike any other vehicle on the market, “Although Audi’s seven-seat Q7 and BMW’s X5 cost tens of thousands dollars less than the big Mercedes, they don’t offer the same passenger or cargo room”. This is especially important when thinking about why SUV’s are typically purchased. SUV’s serve a purpose of being able to transport a group of people. When the Mercedes GL500 offers superb passenger and cargo room, this is what differentiates the vehicle right off the bat.
