Maremlyn Sport Body Kit Review: BYD Atto 3 (2nd Gen) Full Kit — Front Lip, Side Skirts & Rear Diffuser

The Verdict at a Glance

The BYD Atto 3 already stands out with its sculpted, blade-like design language — but its softly rounded bumpers leave the car looking a little polite from the front and rear. Maremlyn's ABS Sport Full Body Kit fixes exactly that. Developed from a 1:1 3D-scan of the facelifted second-generation Atto 3, the three-piece set (front lip, side skirts, rear diffuser) sharpens every panel line, tightens the stance, and — thanks to the drill-free adhesive mounting — does it all without a single hole in your factory paint.

Rating: 4.8 / 5 — Best-in-class fitment for the price, with true DIY-level installation.

From the Factory Floor: A Kit Born from a Development Showcase

Maremlyn recently published a development showcase on its official channel — "Focusing on Popular EV Models | BYD ATTO 3 (2nd Gen) Kit Development Showcase" — and it's worth watching before you buy:

The clip pulls back the curtain on how the kit is made: the team at Maremlyn runs the latest production-model Atto 3 through industrial 3D scanners, digitising the body surface point-by-point before any mold is cut. That scan data becomes the master mold for the injection-molded ABS panels you receive — which is why the kit follows the car's compound curves instead of fighting them.

With four production bases, a dedicated R&D team, and more than 300 registered design patents (China, Thailand, Japan, Australia), this isn't a universal "one-size-fits-all" body kit. It's a model-specific program, and the Atto 3 (2nd Gen) is one of its flagship releases.
 

What's in the Box

Each piece ships with the factory mounting hardware — automotive clips plus high-bond 3M tape — so the box is complete the moment it arrives. No brackets to fabricate, no trimming required.

Material & Build Quality: Why ABS, Not Cheap PP

The single biggest quality signal on this kit is the material choice: thick, automotive-grade ABS plastic.

• Impact-resistant — ABS absorbs stone chips and low-speed knocks far better than thin PP or fibre-reinforced budget kits.
• Anti-UV — the compound is formulated to resist yellowing; even after long-term direct sunlight exposure the surface stays consistent with the factory bodywork.
• No fading — colour depth and gloss are maintained under harsh UV, an area where cheap injection-molded kits visibly fail within a season.

For a daily-driven EV in almost any climate, this matters more than carbon-look aesthetics. A body kit that turns chalky after a year of parking outside is worse than no kit at all — and Maremlyn's ABS formulation is specifically engineered against that failure mode.
 

 

Fitment: 1:1 3D-Scanned, Zero Cutting

The defining test of any aftermarket body kit is whether the panel gaps line up. Because the mold was cut from a real-car 3D scan of the 2nd-gen Atto 3:

• Seamless fit along the bumper and rocker contours — no visible gaps or proud edges
• No cutting or grinding required — the pieces land exactly where the factory body lines are
• No paint damage — nothing is drilled, screwed, or bonded over your paint in a way that can't be removed

This is the key difference from universal "sport lip" products: the Maremlyn kit is made for this car, and it shows in the finished silhouette. The fit is designed for both the BYD Atto 3 (2nd Gen) and the Yuan Plus EV (the same vehicle sold under its Chinese-market name).
 

On the Road: Aero & Stability

The styling upgrade is obvious, but the kit pulls double duty on the engineering side:

• Reduced high-speed wind drag — the streamlined lips and diffuser channels tidy airflow around the bumper edges
• Improved driving stability — the streamlined side skirts and rear diffuser calm the turbulent zones along the rocker panels and under the rear bumper at highway speeds

On an EV, efficiency is king. A cleaner air path around the body means the car works less to push through the air — and owners report the car feels more planted and quieter on motorway stretches with the kit fitted. The numbers are modest, but the feel is real, and every bit of range matters.
 

Durability: All-Weather, Long-Term

Maremlyn spec'd the kit for daily abuse:

• Waterproof & scratch-proof surface treatment
• All-weather durable — heat, cold, rain, and road salt handled without warping or cracking
• One-year warranty backed by the manufacturer, with an installation manual included in every shipment
   

What We'd Improve

No review is complete without the honest caveats:

• Adhesive is permanent-ish — while removal doesn't damage paint, the tape residue needs careful cleanup. Fit it once, fit it right.
• Gloss black requires care — like all gloss ABS, avoid harsh car-wash brushes; hand-washing keeps the finish mirror-clean.

None of these are deal-breakers. They're just the realities of any quality ABS body kit.
 

Final Verdict

Overall: 4.8 / 5

If you own a BYD Atto 3 (2nd Gen) or Yuan Plus EV and want the car to finally look as quick as it is, the Maremlyn Sport Full Body Kit is the cleanest path to get there — factory-grade fit, no drilling, no paint damage, and a proper sport stance that survives daily life. It's the kind of product that makes you understand why Maremlyn's development showcase is focused on popular EV models: this is what a model-specific kit should feel like.
