Story

Crimson Silhouette Protocol takes the 2005 Buick Rendezvous—peak suburban appliance—and rebuilds it as a Group 5 Super Silhouette homage that still reads unmistakably “Rendezvous” from 50 feet. The greenhouse stays tall, the beltline stays honest, but everything below it is re-architected: squared box flares, hard edges, and exposed aero that turns family-car proportions into a legitimate circuit weapon.

The attitude is pure late-’70s/early-’80s: exaggerated width, brutal cooling, and a livery that looks like it rolled out of a paddock full of cigarette-stained clipboards and tire carts. It’s not a joke build—it’s a track-width monster with real ducting, real downforce hardware, and the kind of stance that only makes sense when the stopwatch is the only judge.

Technical dossier

Fictional engineering concept

Platform

2005 Buick Rendezvous

Powertrain concept

GM LS-based V8 swap (6.2L architecture) tuned for track reliability and broad torque
Dry-sump oiling and baffled fuel system to survive sustained lateral load from the widened track
High-capacity cooling: front radiators plus auxiliary heat exchangers fed by side tunnels
Motorsport ECU with data logging and fail-safes for coolant/oil pressure and IAT

Aero package

240mm-projection multi-plane carbon splitter with tall vertical dive planes and corner canards
Stepped side skirts with integrated side air tunnels feeding mid-chassis cooling
Full-width rear diffuser with multi-strake layout and long overhang for underbody expansion
1800mm dual-element wing on swan-neck uprights with adjustable flap

Chassis & stance

2005 Buick Rendezvous

Wheels & tires

Front: 18x11 forged center-lock wheels with 335/30R18 semi-slicks
Rear: 18x12 forged center-lock wheels with 345/30R18 semi-slicks
Motorsport hubs/center-lock conversion with endurance-grade studs, bearings, and brake hat interfaces
15mm static arch-to-sidewall clearance targeted for compression and alignment change under load

Fabrication notes

Widebody built as a silhouette shell: boxed flare structures tied into inner arches and cage nodes
Splitter and diffuser mounted to chassis hardpoints with serviceable quick-release interfaces
Ducting is sealed (not decorative): brake inlets, fender extraction, and roof evacuation paths
Suspension pickup reinforcement and corrected geometry to match the 300mm track increase
