Technical Specifications of the bmw m3 competition 2020​

The heart of this beast is the S55 engine, a 3.0-liter twin-turbocharged inline-six that produces a staggering 444 horsepower. This is a significant jump over the standard M3, thanks to factory tuning and a more aggressive exhaust setup.

Torque remains a stout 406 lb-ft, delivered across a wide power band that makes highway passing effortless. The Competition Package also includes the Adaptive M Suspension, which was re-tuned with new springs, dampers, and anti-roll bars.

You also get the iconic 20-inch forged 666M wheels, which are as much a styling statement as they are a performance choice. These wheels are wrapped in high-performance rubber to handle the increased lateral grip provided by the active M differential.

Transmission Options

While many enthusiasts opted for the 7-speed Dual-Clutch Transmission (DCT) for its lightning-fast shifts, a 6-speed manual was still available for the purists. The DCT is particularly impressive on track, offering rev-matching and multiple drive modes.

If you have the DCT, you will notice the shifts are crisp and immediate, especially in the most aggressive S3 setting. For DIYers, servicing the DCT fluid is a more complex task than a standard manual gear oil change.

Chassis and Braking

The Competition model features a lightened Carbon Fiber Reinforced Plastic (CFRP) strut tower brace that improves front-end rigidity. This helps the car turn in with a level of precision that few four-door sedans can match.

Standard brakes are massive four-piston front calipers, but some models come equipped with Carbon Ceramic Brakes. You can identify these by their gold calipers; they offer incredible fade resistance but come with high replacement costs.

Essential Maintenance Schedule for the S55 Engine

To keep your bmw m3 competition 2020 running at its peak, you must adhere to a strict maintenance schedule. High-performance engines are less forgiving of neglected fluids or old filters than your average commuter car.

I recommend shortening the factory oil change intervals if you drive the car spiritedly or take it to the track. While BMW suggests longer intervals, most experts agree that 5,000 to 7,500 miles is the sweet spot for engine longevity.

Always use a high-quality LL-01 certified synthetic oil, typically in a 0W-30 or 5W-30 weight. Using the correct oil ensures the VANOS system and turbochargers receive proper lubrication during cold starts and high-heat scenarios.

DIY Oil Change Steps

1. Warm the engine to operating temperature to ensure the oil flows freely during drainage.
2. Lift the car safely using a floor jack and jack stands, or use a set of sturdy ramps.
3. Locate the 17mm drain plug on the oil pan and the oil filter housing on top of the engine.
4. Replace the filter element and the O-rings, ensuring you lubricate the new seals with fresh oil.
5. Torque the drain plug to 25 Nm and refill with approximately 6.5 liters of approved synthetic oil.

Spark Plugs and Ignition Coils

The S55 engine is sensitive to spark plug gaps, especially if you plan on adding a performance tune later. Factory intervals suggest replacement every 30,000 miles, but tuned cars should see new plugs every 15,000 miles.

You will need a 14mm thin-wall spark plug socket to reach the deep wells in the cylinder head. Be careful when removing the ignition coils, as the plastic locking tabs can become brittle over time due to engine heat.

Common Problems and DIY Troubleshooting

Every performance car has its “Achilles’ heel,” and the bmw m3 competition 2020 is no exception. Being aware of these issues allows you to catch them before they turn into expensive repairs at the dealership.

One common complaint is the crank hub issue, where the timing gear can slip, leading to catastrophic engine timing failure. While rare on stock cars, it is a known risk for those pushing high boost levels through aftermarket tuning.

Another area to watch is the charge pipes. The factory units are made of plastic and are known to crack or “pop” under high pressure, leading to a sudden loss of power and a drivetrain malfunction warning.

Inspecting for Oil Leaks

Keep an eye on the valve cover gasket and the oil filter housing gasket, as these are common leak points on BMW inline-six engines. If you smell burning oil after a drive, it is likely dripping onto the hot exhaust manifold.

Replacing a valve cover gasket is a labor-intensive DIY job but can be done with basic hand tools and patience. Always use a torque wrench when tightening the valve cover bolts to avoid cracking the plastic cover.

Cooling System Health

The M3 uses a sophisticated air-to-water intercooler system that relies on a dedicated cooling circuit. Check the coolant levels in both the main reservoir and the smaller intercooler reservoir regularly.

If you notice the car pulling timing or feeling sluggish in hot weather, the intercooler pump might be failing. A quick scan with an OBDII diagnostic tool can often reveal hidden codes related to cooling performance.

Performance Upgrades for the F80 Chassis

The bmw m3 competition 2020 is already a powerhouse, but the aftermarket support for this platform is massive. Whether you want a better sound or more grip, there are proven paths to follow.

The first mod many owners choose is a set of aluminum charge pipes. These replace the failure-prone plastic units and provide peace of mind, even if you stay at stock power levels.

Exhaust modifications are also popular, as the S55 engine has a unique, somewhat raspy tone. An equal-length mid-pipe can transform the exhaust note into something much smoother and more exotic sounding.

Software Tuning and Bootmod3

Platforms like Bootmod3 allow you to flash the Engine Control Unit (ECU) from your driveway using a laptop or phone. A “Stage 1” tune can easily add 50-70 horsepower without requiring any hardware changes.

However, once you start increasing power, you must consider the limits of your tires and brakes. Always ensure your maintenance is up to date before adding more stress to the engine and drivetrain.

Suspension and Handling

While the Competition suspension is excellent, some owners find it a bit harsh for daily driving on poor roads. Swapping to a set of high-quality coilovers can actually improve ride quality while lowering the center of gravity.

For those who track their cars, adjustable camber plates are a must-have. They allow you to dial in more negative camber, which saves the outer edges of your front tires during hard cornering.

Interior Care and Technology

Inside the cabin, the 2020 model features the iDrive 6.0 system, which is intuitive and supports wireless Apple CarPlay. Keeping the leather and carbon fiber trim clean is essential for maintaining the car’s resale value.

Use a dedicated leather cleaner and conditioner to prevent the Merino leather seats from cracking or fading. Avoid using harsh chemicals on the carbon fiber trim, as they can damage the clear coat over time.

If your steering wheel is wrapped in Alcantara, it will require regular cleaning with a damp microfiber cloth. This prevents the oils from your hands from matting the fibers down and making the wheel feel greasy.
