CMST Phantom Carbon Fibre Body Kit for Xpeng P7
The CMST Phantom (幻影) body kit for the Xpeng P7 is a full carbon fibre aero package comprising a front lip, four-piece canard set, two-piece side skirts, and a rear lip — all manufactured in carbon fibre. The kit is purpose-designed for the Xpeng P7, a Chinese electric sports sedan produced from 2020. Every piece is carbon fibre rather than FRP, making this a carbon-only build rather than the mixed-material approach CMST uses on some other platforms. The result is a car that retains the P7's clean factory silhouette while adding hard-edged aero references at the front chin, rocker panels, and rear lower section.

About the Xpeng P7 Platform
The Xpeng P7 is an electric sports sedan built on XPeng's proprietary EV platform, with a drag coefficient of 0.236 Cd in standard specification — one of the lowest for a production EV of its era when launched in 2020. The P7's production body uses flush door handles, a fastback roofline, and a near-absent front grille (replaced by a closed panel), which gives the car an unusually clean exterior surface from which to start a modification build.
That cleanliness is also a constraint. Because the P7 has so little surface detail at the lower body, the contrast between the car's painted surfaces and the CMST carbon fibre pieces is more pronounced than it would be on a more surfaced conventional ICE vehicle. This is not a problem — it is the design intent. The carbon pieces are meant to read as deliberate additions rather than body-coloured extensions.
Front Lip — Carbon Fibre
The CMST Phantom front lip attaches below the P7's lower front bumper apron. In source material it is described as giving the front face a more aggressive, fighter-jet quality — the lip's forward edge is sharp and the underside is shaped to complement the P7's existing lower bumper geometry rather than covering it. The lip is a bolt-and-clip fit to the existing front apron without requiring bumper modification.
On an EV sedan like the P7, the front lip does not interact with an air intake in the way it would on an ICE car — the P7's lower fascia has no radiator intake requirement. The lip is therefore a purely aero and visual addition; it reduces the frontal airflow under the car and changes the visual mass of the nose from this angle. Because the P7's active aerodynamics engage at highway speed, the passive contribution of a front lip supplement is additive rather than conflicting.
Canards — Four-Piece Carbon Fibre Set
The canard set is one of the more distinctive elements of the Phantom kit. Four separate carbon fibre canard fins attach at the front corners of the front bumper — two per side in a stacked arrangement. Canards at this location generate a small amount of downforce at the front axle at speed and, more practically, alter the aerodynamic behaviour of the air flowing around the front wheel arches.
At legal road speeds the downforce contribution is modest, but the visual effect is significant: four-piece canards read immediately as a motorsport reference, particularly against the P7's otherwise minimal front fascia. Carbon fibre is the standard material for canards across performance applications because the pieces are small, highly loaded, and need to be stiff without adding mass at the extreme front of the car where unsprung weight matters.
Side Skirts — Two-Piece Carbon Fibre
The side skirt set is a two-piece carbon fibre lower sill extension, one for each side. Each piece runs from the rear of the front wheel arch to the front of the rear wheel arch — the full sill length. On the P7's flush-sided body, the skirts add a horizontal visual element that bridges the front and rear aero pieces and lowers the visual centre of gravity of the car in side profile.
The P7's sill section is lower than most ICE sedans of equivalent size (the EV battery floor lowers the effective ride height). This means the side skirts on the Phantom kit are narrower in drop height than equivalent pieces on higher-riding vehicles. The tight clearance to the ground also means side skirt fitment requires extra care to ensure the lower edge does not contact speed humps or steep driveways.
Rear Lip — Carbon Fibre
The rear lip replaces the P7's standard lower rear bumper panel with a carbon fibre unit. CMST describes this as adding muscle and visual depth to the rear end — the factory P7 lower rear panel is a relatively flat, painted section, and the carbon lip introduces a more layered and three-dimensional treatment at the rear. The fitment covers the full width of the rear bumper lower section.
In combination with the P7's factory active rear spoiler (which deploys at highway speed on the standard P7), the carbon rear lip adds a visual base line that makes the rear section look more deliberately resolved. The rear lip attaches by clip and adhesive to the lower rear bumper, following the same mechanical method as the front lip.
Why Carbon Fibre on an Electric Sports Sedan
The P7 weighs approximately 1,950–2,080 kg depending on battery specification. The CMST aero pieces reduce overall vehicle mass only marginally — individual carbon pieces in this size class weigh 0.5–2 kg each, so the full kit saves perhaps 5–8 kg versus equivalent FRP pieces. That is not the primary reason for using carbon on this platform.
The more substantive argument is material-to-vehicle coherence. The P7 occupies the premium electric sports sedan category — a space defined more by technology and precision than by traditional automotive luxury markers. Carbon fibre reads within that context as a material that belongs: it is associated with engineering precision and lightweighting in motorsport and aerospace, which aligns with the P7's EV-technology positioning better than, for example, gloss-black painted FRP.
Buyers who want the Phantom kit look without the carbon price point can request FRP alternatives for the side skirts and rear lip (the pieces least visible at normal viewing angles), while retaining carbon for the front lip and canards where the weave texture is most prominent.
Fitment Notes for Australian Buyers
The Xpeng P7 is available in Australia through XPeng's local distribution, which began in 2024. The P7 sold in Australia uses the same exterior body shell as the Chinese-market vehicle, so CMST's Phantom kit fitment is direct. Buyers should confirm their specific bumper variant (the P7 was updated in 2021 with a revised front fascia) against the CMST kit specification before ordering.
Professional fitment by a workshop familiar with low-riding EV platforms is recommended for the side skirts, given the tight sill-to-ground clearance on the P7. The canard set can be owner-installed with standard tools, but the front lip adhesive bond should be done by an experienced fitter to ensure the bond line is solid and sealed.

Frequently Asked Questions
What is the Xpeng P7 and is the CMST Phantom kit available in Australia?
The Xpeng P7 is an electric sports sedan produced by XPeng (also written as XPEV), a Chinese EV manufacturer, from 2020. The P7 is available in Australia through XPeng's local distribution. The CMST Phantom body kit for the P7 is available through AME Motorsport for Australian buyers.
Does the Phantom kit include all carbon fibre pieces or is any part FRP?
The Phantom kit for the P7 is specified as a full carbon fibre build — front lip, canards, side skirts, and rear lip are all carbon fibre with clear coat. CMST does not list an FRP option for this specific kit, though FRP alternatives may be available on request. Confirm current variant availability with AME Motorsport before ordering.
What do canards actually do on a road car?
Canards are small aero fins mounted at the outer front corners of the bumper. At highway speed they generate a small amount of front-axle downforce and alter airflow behaviour around the front wheel arches, which can reduce aerodynamic lift. At city speeds the effect is minimal. On a road car the primary role of canards is visual — they reference the leading-edge devices used on racing car front splitters and establish the car's performance intent.
Will the side skirts scrape on Australian speed humps?
The P7's battery-floor architecture means ride height is lower than a comparable ICE sedan. Adding side skirts with a downward extension reduces the clearance to road obstacles further. On standard Australian asphalt speed humps (typically 75–100 mm high), the risk of skirt contact depends on the P7's current ride height and suspension setting. Measure clearance from the skirt lower edge to the ground after installation and approach steep driveways and speed humps at an angle.
Can the canards be removed if I change my mind?
Canards are typically mechanically fastened with bolts into the bumper — they do not use structural adhesive in the same way as front or rear lips. Removal requires unbolting the fasteners and filling or covering the mounting holes. The bolt pattern is small (typically M5 or M6) and can be filled with colour-matched paint if the car is returned to standard.
How does the CMST Phantom kit affect the P7's factory drag coefficient?
The P7's factory Cd of 0.236 is achieved with the standard closed-nose panel and flush body surfaces. Adding a front lip and canards generally increases frontal area and alters the pressure distribution under the car. The net effect on the Cd figure depends on specific airflow patterns and is not measurable without wind tunnel testing. At highway speeds the kit may reduce aerodynamic lift rather than meaningfully reducing drag — which for a road car is the more practically useful aerodynamic outcome.
