Performance Upgrades: Unleashing More Power

The heart of any Mercedes-Benz is its engine, and the 2016 GL-Class offered several robust options, including the GL450 (3.0L V6 biturbo) and the GL550 (4.6L V8 biturbo). Performance upgrades focus on optimizing airflow, fuel delivery, and engine management to extract more power safely and efficiently.

ECU Tuning (Engine Control Unit)

The most common and effective performance upgrade is ECU tuning, often referred to as “chipping.” This involves reprogramming the vehicle’s main computer to optimize engine parameters. For the 2016 GL-Class, reputable tuners can:

• Increase Horsepower and Torque: Gain noticeable improvements across the RPM range.
• Improve Throttle Response: Make the acceleration feel more immediate.
• Optimize Gear Shifts: Enhance the transmission’s performance to match the engine’s output.

Reputable tuning companies like Renntech specialize in Mercedes-Benz tuning and offer carefully developed software upgrades. They ensure that the modifications are safe for the engine and drivetrain components. A typical ECU tune for a GL450 might add around 30-40 horsepower and a similar amount of torque, while a GL550 could see even greater gains.

Exhaust System Upgrades

While the stock exhaust is designed for quiet luxury, an aftermarket performance exhaust can improve exhaust flow, reduce weight, and enhance the engine’s sound. For a GL-Class, the goal is usually a sportier tone without being overly intrusive.

• Cat-Back Systems: These replace the mufflers and exhaust tips, offering a moderate increase in performance and a noticeable change in sound.
• Performance Headers: More extensive upgrades that can significantly improve exhaust scavenging and power, though they are more complex to install and can affect emissions compliance.

Brands like Borla offer exhaust systems that can provide a richer, more aggressive sound profile while improving the flow of exhaust gases.

Cold Air Intakes

A cold air intake system replaces the restrictive factory airbox and fluid lines with smoother, larger diameter tubing and a high-flow air filter. This allows the engine to breathe more easily by drawing cooler, denser air.

• Pros: Modest power gains, improved engine sound, and a more aggressive appearance under the hood.
• Cons: Gains are often modest without other supporting modifications. Installation can vary in complexity based on the kit.

Companies like AEM offer universal components and specific kits designed to fit various applications, though you’ll want to ensure compatibility with the 2016 GL-Class’s engine bay layout.

Upgraded Intercoolers (For Turbocharged Models)

For turbocharged models like the GL450 and GL550, the intercoolers are responsible for cooling the compressed air from the turbochargers before it enters the engine. Upgraded, larger intercoolers can maintain cooler intake air temperatures more effectively, especially under heavy load or after repeated acceleration, leading to more consistent power output and reduced risk of engine knock.

Handling and Suspension Upgrades

The GL-Class boasts Mercedes’ renowned AIRMATIC suspension, offering a comfortable and adaptive ride. However, upgrades can further refine its dynamics, whether you seek sportier handling or a more refined cruising experience.

Performance Lowering Springs

If you desire a sportier stance and improved cornering stability, performance lowering springs are a popular choice. They replace the stock springs, lowering the vehicle’s center of gravity. This can reduce body roll in corners and give the GL-Class a more aggressive look.

• Considerations:
• Ride Comfort: Lowering springs can make the ride firmer.
• AIRMATIC Compatibility: Ensure any spring upgrade is compatible with the AIRMATIC system to avoid error codes or damage. Some systems require specific modules to compensate for the lowered height.
• Wheel Alignment: A proper wheel alignment is crucial after any suspension modification.

Brands such as Eibach offer progressive lowering springs designed to maintain a reasonable level of comfort while improving handling characteristics.

Performance Tires

Tires are the most critical contact point between your vehicle and the road. Upgrading to high-performance tires can drastically improve grip, handling, braking, and overall driving feel.

• Look for: Ultra-high performance (UHP) summer tires for maximum grip in dry and wet conditions, or all-season UHP tires for a balance of performance and all-weather capability.
• Consider: Tires with a lower aspect ratio (e.g., 35 or 40 series) for a more responsive feel, but be mindful of potential ride harshness.

Leading tire manufacturers like Michelin (Pilot Sport series), Pirelli (P Zero series), and Continental (ExtremeContact series) offer excellent options that will fit the 2016 GL-Class. Always ensure your chosen tires are the correct size and load rating for your vehicle.

Sway Bar Upgrades

Upgraded sway bars (anti-roll bars) can significantly reduce body roll during cornering. They connect the left and right suspension components, resisting the tendency for the body to lean. This upgrade offers a noticeable improvement in handling precision without usually compromising ride comfort.

While not as common as other upgrades for a luxury SUV, performance sway bars can be found from specialized manufacturers catering to Mercedes-Benz vehicles. Always consult with an expert on compatibility with the AIRMATIC system.

• Subwoofer Addition: A custom-mounted subwoofer can add depth and richness to the audio experience, particularly for bass-heavy music genres.

Custom Interior Refinements

Personalization is key to making any vehicle truly yours.

• Custom Stitching or Upholstery: Updating leather seats, steering wheel, or door panels with custom stitching or premium materials can add a bespoke touch.
• Ambient Lighting: Adding or upgrading interior ambient lighting can transform the cabin’s mood and enhance its luxurious feel, especially at night. Many aftermarket kits offer a wide spectrum of colors and dynamic effects.
• All-Weather Floor Mats: While not strictly a luxury upgrade, high-quality all-weather floor mats from brands like WeatherTech are essential for protecting the original carpeting from dirt, moisture, and wear, especially in a family vehicle.
• Carbon Fiber or Wood Trim Kits: Replacing existing trim pieces with genuine carbon fiber, high-gloss black, or exotic wood veneers can significantly alter the cabin’s aesthetic.

Driver Assistance Technology

While the 2016 GL-Class came with many safety features, newer technologies have emerged.

• 360-Degree Camera Systems: For easier parking and maneuvering, an aftermarket 360-degree camera system can be integrated, providing a bird’s-eye view of the vehicle’s surroundings.
• Dashcams: A high-resolution dashcam is a practical addition for recording drives, providing evidence in case of accidents, or capturing scenic routes. Brands like Thinkware offer advanced models with parking mode capabilities.

Wheels and Exterior Upgrades

The wheels and exterior styling are crucial elements that define a vehicle’s presence.

Aftermarket Wheels

Upgrading to larger or more stylish aftermarket wheels can dramatically change the GL-Class’s appearance. Consider:
