Phantom Vector Program

Layered carbon splitter projecting +180mm with triple dive planes per side (100mm tall, 20° outward)
Carbon hood with recessed central intake (530x320mm) and twin heat extractors (350x90mm)
Extended side skirts forming a 75mm aero shelf with a 140mm concave acceleration channel
Venturi diffuser dropping 270mm with seven 115mm strakes across ~1400mm width
Dual-element rear wing (1680mm span) on swan-neck pylons, ~820mm above deck, adjustable AoA/camber

Set on a European endurance pit lane at dawn, the car reads like a test-day prototype: low, wide, and busy with cooling exits. The scene suits the build’s intent—long stints, heavy braking zones, and aero balance adjustments made with a wrench, not a menu.

Enkei Racing forged: 18x11 front, 18x12 rear in matte gunmetal
Slicks: 330/680R18 front and rear (staggered wheel width for balance and carcass support)
Race brake package with splitter-edge inlet ducts and fender-exit management for rotor temps

Rear-mid mounted turbocharged 2.0L inline-four tuned for endurance response and thermal stability
6-speed sequential transaxle with motorsport clutch and flat-shift strategy
Exhaust-forward rear packaging to preserve diffuser volume and reduce underfloor disruption
Motorsport ECU with data logging focused on boost control, EGT management, and traction calibration

Bespoke rear-mid chassis cell tied into a reinforced safety structure and suspension pickup points
Pushrod suspension packaging with inboard dampers for reduced unsprung mass and cleaner aero
Functional ducting: sidepod intercooler routing, hood extraction, and controlled rear exit paths
Panel strategy in carbon composite with serviceable fasteners for quick pit-lane access

Phantom Vector Program takes the 2011 Elantra’s familiar greenhouse and uses it as the only “street car” reference point in an otherwise open-rule prototype. The body is re-authored into squared-off, vented widebody volumes with proper sidepod cooling, a layered splitter with multi-plane management, and a rear floor that’s built around diffuser volume instead of bumper cosmetics.

Under the skin, it’s the kind of mechanical betrayal that makes the concept work: a rear-mid turbo four on a sequential, pushrod double-wishbones at both ends, and track width pushed out until the car reads like a compact LMP silhouette. It’s still recognizably Elantra in profile—just engineered like it’s supposed to run long stints at full aero load.
