The Mercedes-AMG GT 4-Door Coupé X290 is AMG's bespoke four-door grand-tourer — a low-slung, AMG-developed sister to the standard CLS C257 and the E-Class W213, sharing the AMG-tuned MRA platform but with unique X290 sheetmetal, AMG-only chassis hardware and an AMG-specific cabin. Launched in 2018, the X290 GT 43 and GT 53 are the inline-six EQ Boost variants of the range, sitting below the V8 GT 63 and GT 63 S. Both run the M256 3.0 L turbo inline-six with EQ Boost 48 V mild-hybrid — 367 PS / 500 Nm + 22 PS on the GT 43, 435 PS / 520 Nm + 22 PS on the GT 53. Power is channelled through the 9G-TRONIC nine-speed automatic to permanent 4MATIC+ AWD with rear-axle bias; suspension is AIRMATIC adaptive air with continuously variable damping, with optional rear-axle steering and AMG Active Ride Control on the higher-spec packages.
The Larte Winner programme is Larte Design's headline body-kit for the X290 — a coherent aero schedule giving the GT 43 / GT 53 a visual presence closer to the V8 GT 63 S without the V8 premium. Sister Larte Mercedes programmes include the Larte Charisma for the Maybach GLS 600 Facelift X167. The full Larte Design collection sits alongside our Mercedes-Benz body-kit catalogue and the wider body kits range.

The Winner schedule is calibrated to the X290's restyled 2021+ facelift front-fascia (revised AMG Panamericana grille, slimmer LED daytime-running-light signature). Pre-facelift 2018–2020 X290 donors are served by the original Winner schedule — VIN-specific bumper-attachment variants are identified at order intake.
Engineered around the X290 GT 43 and GT 53 body lines. Dimensionally compatible with the V8 GT 63 and GT 63 S donors on the same X290 shell — the V8 cars use a different factory front-bumper and rear-diffuser, but Winner panels are calibrated to fit either AMG variant. Pre-facelift 2018–2020 X290 donors are served VIN-specifically; cross-fitment is handled through our Custom Body Kit Design & Manufacturing Service.
X290 factory wheels run 19–21" AMG forged. Winner builds typically step to 21"/22" staggered Larte forged monoblock or three-piece designs. Browse the full forged-wheel catalogue or specify a one-off through our Custom Forged Wheels Manufacturing service. Typical fitment 275/35 R21 / 305/30 R22 — full clearance for the AMG carbon-ceramic brake package.

Will Winner panels fit the V8 GT 63 / GT 63 S?
Yes — the X290 body shell is shared across all four-door variants. V8 cars use a different factory front bumper and diffuser, and Winner ships with V8-fitment variants on GT 63 / GT 63 S orders.
Does the kit work with the AMG E-Performance GT 63 S PHEV?
Yes — the GT 63 S E-Performance PHEV uses the same X290 body shell. Winner panels fit; we coordinate cooling-aperture placement around the PHEV battery-pack heat dissipation at order intake.
Does the front-bumper attachment preserve AMG ECO Stop/Start radar and 360-degree cameras?
Yes — all radar, camera and PDC apertures are pre-machined to factory specification; calibration is preserved after fitment.
