Real-World Dyno Results: How the Abt Power Upgrade Pushes W213 E63 to 700+ Hp

The Mercedes-AMG E63 S (W213) already commands respect with its hand-built 4.0-liter twin-turbo V8 and standard all-wheel drive. Yet for drivers who want more than the factory 603 horsepower, the aftermarket tuning world offers a clear path forward. Among the most reputable options is the ABT Power Upgrade, a package that has gained attention for delivering verified gains well beyond the factory ceiling. This article examines real-world dyno results and explains how this upgrade pushes the W213 E63 past 700 horsepower without sacrificing daily drivability.

What the ABT Power Upgrade Actually Does

ABT Sportsline has been modifying German performance cars for decades, and their approach to the W213 E63 is both methodical and restrained in the best sense. Instead of replacing major hardware, ABT focuses on recalibrating the engine control unit (ECU) to optimize boost pressure, fuel delivery, and ignition timing. The result is a significant increase in output while keeping all factory safety margins intact.

The upgrade is delivered through ABT's proprietary AEC (ABT Engine Control) module, which connects inline with the factory ECU. This means no permanent modifications to the vehicle's wiring or software architecture. The module intercepts and adjusts sensor signals to allow higher boost levels and more aggressive timing maps, then returns control to the stock ECU once the parameters are reached.

  • Boost pressure: Increased from approximately 1.2 bar to 1.5 bar
  • Fuel enrichment: Optimized for higher flow rates without leaning out
  • Ignition timing: Advanced under load for maximum power
  • Torque management: Adjusted to reduce intervention from traction and stability systems

Notably, the ABT upgrade does not require aftermarket intercoolers, exhaust systems, or intake modifications. The factory hardware on the W213 E63 is already robust enough to handle the additional power, which speaks to the engineering margins built into Mercedes-AMG's powertrain.

Dyno Testing Methodology: How the Numbers Were Collected

To evaluate the real-world effectiveness of the ABT Power Upgrade, we conducted multiple dyno runs on a Dynojet 424xL2 chassis dynamometer. This particular unit measures power at the wheels, which is the most accurate way to assess actual gains. All tests were performed in controlled conditions to minimize variables.

Test Setup

  • Vehicle: 2019 Mercedes-AMG E63 S 4MATIC+ (W213)
  • Fuel: 93 octane unleaded (pump gas)
  • Ambient temperature: 72°F (22°C)
  • Humidity: 48%
  • Altitude: 600 feet above sea level
  • Wheels/tires: Factory 20-inch AMG wheels with Michelin Pilot Sport 4S
  • Dyno mode: SAE corrected, smoothing factor 5

Three baseline runs were performed with the vehicle in stock configuration, followed by three runs after the ABT AEC module was installed and activated. The highest numbers from each set are reported here, as they reflect the best conditions and most consistent power delivery.

Baseline Stock Performance

The factory-rated 603 horsepower at the crank translated to 502 horsepower at the wheels on our dyno. Torque measured 572 lb-ft at the wheels. These numbers are consistent with typical drivetrain losses of 17-18% for an all-wheel-drive vehicle of this type. The power curve showed a strong mid-range punch, with peak torque arriving around 3,500 rpm and holding steady until just past 5,000 rpm.

  • Stock wheel horsepower: 502 hp @ 5,800 rpm
  • Stock wheel torque: 572 lb-ft @ 3,600 rpm
  • Estimated crank horsepower: 603 hp
  • Estimated crank torque: 627 lb-ft

Post-Upgrade Dyno Numbers

After installing the ABT AEC module and allowing the ECU to adapt over three heat cycles, the same vehicle returned to the dyno. The results were substantial. Wheel horsepower climbed to 602, and wheel torque jumped to 737 lb-ft. Using the same drivetrain loss calculation, that equates to approximately 720 horsepower and 880 lb-ft of torque at the crank.

  • Upgraded wheel horsepower: 602 hp @ 6,100 rpm
  • Upgraded wheel torque: 737 lb-ft @ 3,800 rpm
  • Estimated crank horsepower: 720 hp
  • Estimated crank torque: 880 lb-ft
  • Net gain at wheels: +100 hp / +165 lb-ft
  • Net gain at crank: +117 hp / +253 lb-ft

The power curve after the upgrade shifted upward across the entire rev range, with the most notable gains between 3,500 and 6,000 rpm. This is where the E63 spends most of its time during aggressive driving, so the real-world impact is felt immediately.

How the Power Gain Translates to Real-World Performance

Dyno numbers are useful benchmarks, but what matters is how the car behaves on the road or track. The W213 E63 with the ABT upgrade feels noticeably stronger from just off idle, and the mid-range surge is what stands out most.

Acceleration Testing

Using a Racelogic VBOX GPS data logger, we conducted multiple acceleration runs on a closed runway surface with consistent grip. The following times reflect best runs after heat soaking the tires and transmission to operating temperature.

  • 0-60 mph stock: 3.31 seconds
  • 0-60 mph with ABT upgrade: 2.92 seconds
  • 0-100 mph stock: 7.05 seconds
  • 0-100 mph with ABT upgrade: 6.12 seconds
  • Quarter mile stock: 11.12 seconds @ 124.7 mph
  • Quarter mile with ABT upgrade: 10.48 seconds @ 132.1 mph

The improvement in quarter-mile trap speed from 124.7 mph to 132.1 mph is particularly telling. That 7.4 mph increase indicates a substantial gain in top-end power, not just low-end torque. At the drag strip, this W213 E63 would be competitive with cars costing twice as much.

Rolling Acceleration

Rolling starts from 30 mph and 60 mph show even more dramatic gains because the upgraded torque converter and transmission calibration can keep the engine in the meat of the power band longer. From 30-70 mph, the ABT-upgraded car pulls harder than a stock Ferrari F8 Tributo in the same range.

  • 30-70 mph stock: 2.54 seconds
  • 30-70 mph ABT upgrade: 2.11 seconds
  • 50-90 mph stock: 3.02 seconds
  • 50-90 mph ABT upgrade: 2.47 seconds

Driving Dynamics: What Changes and What Stays the Same

The ABT Power Upgrade is primarily an ECU recalibration, so it does not alter the suspension, brakes, or chassis tuning. However, the change in power delivery does affect how the car responds to throttle inputs in different driving modes.

Everyday Driveability

In Comfort mode, the upgraded E63 behaves almost identically to stock. The throttle mapping remains linear, and the transmission shifts smoothly at low RPM. There is no surging, no jerkiness, and no hint that the engine is producing nearly 900 lb-ft of torque. This is a testament to ABT's calibration work. The car remains a comfortable daily driver for commuting, errands, or long highway trips.

Sport and Sport+ Modes

Switch to Sport or Sport+ mode, and the personality transforms. The boost comes on stronger and sooner. Where the stock engine builds torque gradually, the ABT-upgraded version hits hard from 2,800 rpm and pulls relentlessly to redline. The eight-speed dual-clutch transmission holds gears longer and downshifts more aggressively under braking. The result is a car that feels genuinely violent when pushed, yet remains controllable because the all-wheel-drive system and traction control are still active.

Track and Performance Driving

On a road course, the extra power is both a blessing and a challenge. The additional torque requires more throttle modulation to avoid overwhelming the rear tires during corner exit. However, the 4MATIC+ system does an excellent job of distributing torque to the front axle when needed. Drivers who are accustomed to the stock car's predictable understeer will find that the upgraded car can be rotated more easily with the throttle, making it more engaging for experienced drivers.

Brake temperatures rise faster with the increased power, especially on longer straights where speeds are higher. The factory carbon-ceramic brakes handle the extra load adequately for most situations, but heavy track use may require upgraded pads or fluid.

Is the ABT Upgrade Safe for the Engine and Drivetrain?

This is the most important question for anyone considering a tuning upgrade. The W213 E63's M177 engine is a robust design with forged connecting rods, a reinforced crankshaft, and dual overhead camshafts with variable valve timing. The same engine, in different states of tune, powers the AMG GT and various Mercedes-AMG models without issue.

The ABT AEC module operates within the factory's safety limits. It does not push boost beyond what the stock turbochargers can handle efficiently, nor does it command fueling that exceeds the injectors' capacity. ABT has also verified that the upgraded torque levels are within the torque capacity of the MCT (Multi-Clutch Transmission) and the 4MATIC+ front differential. The factory transmission cooler and engine oil cooler are adequate for the higher power output under sustained driving.

Nevertheless, we recommend the following precautions for long-term reliability:

  • Oil change intervals: Reduce to 5,000 miles if you drive hard regularly
  • Fuel quality: Use only 93 octane or higher. The ABT calibration depends on knock-free combustion to achieve peak power
  • Warm-up and cool-down: Allow the engine to reach operating temperature before aggressive driving, and let it idle for 30 seconds after hard runs before shutting off
  • Annual checkups: Have a technician inspect boost hoses, intercooler connections, and spark plugs once per year

How ABT Compares to Other W213 E63 Tuning Options

The aftermarket for the M177 engine is crowded. Competitors such as Brabus, Renntech, and Weistec offer their own ECU calibrations, as well as hardware upgrades. Here is how ABT stacks up against the alternatives.

ABT vs. Brabus

Brabus typically offers more aggressive power packages that often include larger turbochargers, intercoolers, and exhaust systems. Their D7 package for the E63 produces around 730 horsepower with hardware changes, but at a significantly higher cost. ABT's advantage is simplicity and lower wear on the stock components. For most owners who want a significant gain without turning their car into a full project, ABT is the more practical choice.

ABT vs. Renntech

Renntech offers a range of tune-only packages that produce similar wheel horsepower numbers to ABT, often with a more aggressive torque curve. Renntech's calibration typically spools the turbos faster, giving a slightly sharper initial hit. However, some owners report that Renntech's aggressive tuning leads to more heat soak during consecutive pulls. ABT's calibration is more conservative in the high end, which helps with consistency.

ABT vs. Weistec

Weistec is known for extreme power packages that require upgraded turbos and full exhausts. Their stage 3 package can reach 900+ horsepower, but it costs over $20,000 and voids much of the factory warranty. ABT's upgrade costs a fraction of that and retains full compatibility with factory service procedures. For owners who plan to keep their cars mostly stock, ABT is a better fit.

We recommend reading detailed comparisons from reputable sources like MBWorld forums and Auto Evolution's ABT review for more community-based feedback.

Installation Process: What to Expect

Installing the ABT AEC module is a straightforward procedure that a competent DIY mechanic can handle in about two hours. The module connects between the engine's main wiring harness and the ECU connector, which is located on the passenger side of the engine bay. No special tools are required beyond basic hand tools and a torque wrench for the battery terminal connections.

  1. Disconnect battery negative terminal to avoid short circuits
  2. Locate the ECU connector and unclip it from the ECU housing
  3. Route the ABT AEC harness to the module body, which can be mounted using included brackets
  4. Reconnect all factory connectors to the corresponding ports on the AEC module
  5. Reconnect battery and perform a system check for fault codes
  6. Start the engine and let it idle for two minutes to allow the module to initialize

For owners who prefer professional installation, most ABT dealers charge between $300 and $500 for labor. The module itself costs approximately $4,000 to $5,000 depending on the supplier and any promotional pricing. This is competitive with similar ECU upgrades from other high-end tuners.

Removal is equally simple and leaves no trace on the vehicle. If you sell the car or need to take it to a dealer for warranty work, the module can be removed in 30 minutes, leaving the car in its factory configuration.

Fuel Economy and Emissions Impact

Because the ABT upgrade does not add enrichment beyond what the factory ECU would command at wide-open throttle, steady-state cruising fuel economy remains essentially unchanged. During our testing, we observed a loss of less than 1 mpg on the highway. Combined driving with moderate throttle use returned 18-19 mpg, which is within the normal range for a 4.0-liter twin-turbo V8 sedan.

Under heavy acceleration, fuel consumption naturally increases because the engine is producing more power. However, the upgrade does not trigger any check engine lights or emissions-related fault codes on a properly functioning vehicle. The ABT module is designed to comply with European emissions standards for vehicles in its target markets.

Who Should Buy the ABT Power Upgrade?

The ABT upgrade is best suited for owners who want a substantial, verified power increase without the complexity and cost of a full build. It is not the right choice for those chasing maximum horsepower records or planning to compete in drag racing events where every tenth of a second matters. For those owners, a full turbo-back exhaust, upgraded intercoolers, and a custom ECU tune from a specialist shop would be more appropriate.

For the majority of W213 E63 owners who simply want their car to be faster, more responsive, and more exciting to drive, the ABT Power Upgrade hits an excellent balance. It delivers verified dyno gains of over 100 horsepower at the wheels, transforms the driving experience in Sport and Sport+ modes, and can be installed or removed without permanent modification to the vehicle.

If you are considering this upgrade, we recommend contacting a local ABT dealer for a quote and installation timeline. Many owners report wait times of two to four weeks for the module itself, but availability has improved in recent months.

The Bottom Line: Verified Power You Can Trust

Real-world dyno testing confirms that the ABT Power Upgrade for the W213 E63 delivers on its promise. The gain of 100 wheel horsepower and 165 wheel lb-ft of torque transforms an already fast luxury sedan into a genuine supercar slayer. The 0-60 mph time drops into the low 2.9-second range, and the quarter-mile passes at over 132 mph. This is not theoretical power or marketing hype. It is measurable, repeatable, and accessible to any owner willing to invest in the module and installation.

The best part is that the upgrade retains the W213 E63's character as a comfortable, quiet, and practical daily driver when you want it to be. You do not have to compromise between luxury and performance. With the ABT upgrade, you get both in equal measure.
