Carbon Fiber Rear Bumper Diffuser for 2019-2022 BMW 7 Series G11 745e 750i M Sport M760Li LCI
Available in stock (20)
Carbon Fiber Rear Bumper Diffuser for 2019–2022 BMW 7 Series G11 LCI M Sport (745e / 750i / M760Li)
The BMW 7 Series G11 LCI (Life Cycle Impulse Facelift, 2019–2022) introduced a significantly revised rear bumper compared to the Pre-LCI G11 (2016–2018), with a more pronounced lower diffuser section in M Sport specification featuring a wider structured lower channel, revised lateral aperture geometry, and a more aggressive lower rear character. The G11 LCI M Sport rear bumper diffuser is a large, full-width lower rear bumper element — the primary rear aero and visual differentiator between the G11 LCI M Sport and Base rear ends. This carbon fiber rear bumper diffuser is a replacement-style installation engineered for the G11 LCI M Sport rear bumper, directly replacing the factory plastic diffuser section. At 29 kg, this is a premium-scale full rear bumper diffuser system — screws included, professional installation required.
Some BMW G11 7 Series LCI variants are equipped with a rear approach sensor door (part of BMW's Active Reverse Assist / rear proximity sensor system) integrated into the lower rear bumper diffuser area. Installing this carbon diffuser may block or interfere with the rear sensor door's function. If your G11 LCI has a rear sensor door integrated into the factory diffuser section, please contact us with rear bumper photos and your vehicle's option code list before ordering. We can advise on sensor compatibility for your specific build.
- Fits: BMW G11 7 Series LCI M Sport Sedan — 745e / 750i / 750i xDrive / M760Li — 2019, 2020, 2021, 2022
- Does NOT fit: BMW G11 Pre-LCI (2016–2018) — the Pre-LCI G11 M Sport rear bumper has completely different lower diffuser geometry. This diffuser is engineered for the LCI's revised M Sport rear bumper only. NOT compatible with Pre-LCI
- Does NOT fit: BMW G11 Base / Luxury / Design Pure Excellence — non-M Sport G11 rear bumpers have different lower section geometry without the M Sport's structured diffuser channel. This diffuser requires the G11 LCI M Sport rear bumper
- Does NOT fit: BMW G70 7 Series (2023+) — next-generation 7 Series with completely different rear bumper architecture
- Does NOT fit: BMW G12 7 Series LWB — while G12 shares many components with G11, rear bumper fitment should be confirmed separately. Contact us with rear bumper photos for G12 LCI M Sport compatibility
- Contact us with rear bumper photos and build year to confirm G11 LCI M Sport specification before ordering
G11 LCI vs Pre-LCI — Why the Rear Bumper Diffuser Changed
The G11 LCI (2019+) rear bumper in M Sport specification features a substantially revised lower diffuser section compared to the Pre-LCI — wider lower channel geometry, revised lateral lower apertures, and a more aggressive diffuser profile consistent with BMW M Sport's LCI design update that brought the G11 M Sport's rear end closer in character to the M760Li's bespoke rear visual identity. The Pre-LCI and LCI G11 M Sport rear bumper diffuser sections are not interchangeable. This carbon diffuser is engineered and 3D laser-scanned specifically for the LCI M Sport rear bumper geometry — 2019 onward only.
G11 LCI M Sport Engine Coverage — 745e to M760Li V12
This diffuser fits the G11 LCI in M Sport specification across the available engine range: 745e (394 hp, B58 PHEV plug-in hybrid), 750i (530 hp, N63 twin-turbo V8), 750i xDrive (AWD), and M760Li (610 hp, N74 6.6L twin-turbo V12) — all sharing the same G11 LCI M Sport rear bumper diffuser geometry. BMW's flagship V12 M760Li in M Sport LCI specification is confirmed fitment.

Ordered the BMW front bumper fog light grille and the fitment was absolutely perfect. Gloss black finish looks factory-fresh and the quality is outstanding. Installation took about 30 minutes — no drilling required. Highly recommend AlchemyRide!
Marcus R.
Fast shipping, great packaging, and the part arrived in perfect condition. The grille fits my F23 like a glove — exactly as described. Customer service was also super responsive when I had a fitment question. Will definitely order again.

I've bought aftermarket parts from many stores but AlchemyRide stands out for quality and value. The part was well-made, fit perfectly, and the price was very competitive. My BMW looks aggressive and clean — exactly what I wanted.

Excellent product and super easy to install. The gloss black finish matches my M Sport bumpers perfectly. Shipping was faster than expected and the part was well-packaged. Very happy with my purchase — my car looks completely transformed!
