Mercedes-Benz W176 A200/A250 Sport & A45 AMG Carbon Fiber Rear Diffuser, 2013–2018

Carbon Fiber Replacement Rear Diffuser for Mercedes-Benz W176

Add a gloss carbon-fiber finish to the lower rear bumper of your listed W176 A-Class hatchback. The source describes this diffuser as a replacement for the factory plastic diffuser, not a tape-on overlay, complete rear bumper or full body kit.

Listed Vehicle Fitment

• Mercedes-Benz A-Class W176 Hatchback.
• A200 Sport and A250 Sport.
• A45 AMG.
• Source-listed years: 2013, 2014, 2015, 2016, 2017 and 2018.
• Not for W176 Base models. The original exclusion spells the chassis “W76”; the surrounding description identifies W176.

Confirm VIN, production date, regional model year, Sport/A45 AMG bumper specification and factory diffuser mounting profile before ordering. The combined models and years are not a verified model-by-year table. Check pre-facelift and facelift rear bumper arrangements individually rather than assuming every listed vehicle uses the same diffuser and exhaust layout.

The original introduction calls the hatchback “4-Door.” Confirm the actual body and mounting arrangement rather than interpreting that wording as sedan compatibility. Sport package naming varies by market; a badge or AMG-style appearance alone does not establish the correct bumper.

The hidden filters include 2019, diesel/CDI/d and drivetrain-specific entries. These do not independently expand the detailed fitment. Diesel applications, individual drivetrain configurations and 2019 vehicles require separate verification. A180, W177, A-Class Sedan, CLA, GLA, conversion bumpers and aftermarket bumpers are not confirmed applications.

Material and Finish

• Specified material: 3×3 weave carbon fiber.
• Gloss surface with a double-layer UV-protected clear coating.

A dry-carbon process, pre-impregnated cloth, full laminate composition, dimensions, measured component weight and molded piece count are not supplied. Pure-carbon-throughout construction, quantified weight savings and permanent resistance to fading or discoloration are not established.

Replacement Structure and Package Scope

The source specifies replacement-style installation and included self-tapping screws. Remove the original plastic diffuser according to the verified installation procedure before fitting this replacement. Screw quantities, clips, brackets and any additional attachment requirements are not itemized. Tape is not listed as included.

Exhaust tips, exhaust pipes, reflectors, lamps, sensors and wiring are not specified as included. Do not assume that this diffuser includes a complete bumper assembly or converts the vehicle's exhaust arrangement.

Exhaust Compatibility and Heat Clearance

The source does not specify exhaust-opening count, location, dimensions, shape or compatible tip sizes. Match the actual diffuser openings to the individual vehicle's exhaust layout before ordering. Do not infer single-, dual- or quad-tip compatibility from the Sport or A45 AMG name alone.

Have a qualified installer verify clearance around exhaust tips and hot components, allowing for exhaust movement and heat expansion. Retain appropriate original heat shielding where required. Tips must not contact the diffuser or direct hot gases onto the panel. Exhaust modification is not represented as included or automatically required.

Installation Guidance

Professional installation is recommended. Test-fit before drilling, altering original trim or permanently transferring components. Check bumper alignment, the complete mounting footprint and underbody clearance. Do not force a mismatched panel into position.

Self-tapping screws are supplied, so no-drill or no-modification installation is not promised. Have the installer identify suitable mounting points and inspect behind proposed holes to avoid wiring, sensors and other components. Verify retention of original clips or hardware required for the actual bumper.

Preserve lights, reflectors, parking sensors, towing access, drainage and service access where fitted. If the vehicle has hands-free tailgate opening equipment, check sensor location, wiring and operation before and after fitting; compatibility is not established by this listing. This conditional check does not mean every W176 has that feature.

Confirm secure attachment before driving and recheck according to the installer's guidance. Quick installation, a fixed installation time and universal direct fit are not promised. Check clearance over ramps, speed bumps and curbs. This diffuser is not a structural guard or recovery point.

Performance Scope

No measured downforce, drag, cooling, handling or fuel-economy results are supplied. This listing describes an exterior styling replacement rather than a verified aerodynamic improvement.
