2004 Acura 3.5 RL -- Body

The 3.5 RL body design displays a muscular stance and dynamic appearance while maintaining an enduring elegance and sophistication. It provides generous interior space and headroom, especially in the rear seats, coupled with an elegant and substantial exterior appearance. With body-colored lower side sills, splash guards, and roof strips, the 3.5 RL has a strongly masculine appearance, with an efficient, aerodynamic front grille/fender/bumper area.

With an extremely low drag coefficient of 0.32 and a lift coefficient of 0.102, the RL offers impressive high-speed stability and a quiet interior environment.

The RL is engineered and assembled to have a level of fit and finish second to none in the luxury sedan class. Panels have been combined and integrated, wherever possible, to eliminate gaps and seams.

The tall, spacious-feeling greenhouse of the RL is designed to give the driver and passengers a clear, panoramic view of the road ahead and the surroundings to the sides and rear for enhanced safety. The driver's front, side and rear views are largely unobstructed, due to slim, yet highly rigid, roof pillars. The body is designed to give the driver a clear sense of the boundaries of the car for more secure maneuvering and parking.

A special spoiler, located immediately behind the front bumper, streamlines airflow under the RL, reducing the high-pressure air under the front of the body and diverting it to flow around the sides and over the top of the vehicle. This reduces drag and front-end lift and also reduces wind noise, helping to give the RL a remarkably quiet interior, even at high speeds.

The RL is built with a high proportion of galvanized steel panels, most of them galvanized on both sides for superior corrosion protection. All visible surfaces are protected by a 23-step, 4-coat, 4-bake paint process, with special antichip primer and chip-resistant paint used in areas that are likely to be struck by stones or other debris. The paint process is so precise and exacting that painting personnel wear special contamination-free clothing while working and are regularly checked for colognes or other cosmetic chemicals that might cause the slightest contamination of the painting environment. Chassis panels are protected by corrosion-resistant undercoating material, and body cavities are injected with an oil-based anticorrosion wax that displaces moisture for even better protection.

The 2004 RL is available in seven exterior colors including: Indigo Blue Pearl, Nighthawk Black Pearl, Premium White Pearl, Polar Blue Metallic, Satin Silver Metallic, Carbon Gray Pearl, and Champagne Mist Pearl.

The ultra-high quality appearance of the RL is enhanced by a special crystal structure cast into the inner surface of the RL rear outer-lens assembly.

RL side rearview mirrors underscore the extraordinary lengths taken to reduce wind noise. The side rearview mirrors are designed with a small wind deflector, or spoiler, that directs oncoming air down and away from the mirror assembly. By separating or breaking up the airflow under the mirror, the deflector reduces the pressure between the air rushing around the mirror housing and the still air behind the mirror, eliminating the "whistling" effect that has been identified as a cause of wind noise in the wind tunnel.

The RL's innovative power moonroof consists of an outer moonroof panel with one-touch tilt or open controls. Heat-rejecting privacy glass is used, and the moonroof is programmed to pause at the 130 mm position during closing to help ensure passenger safety.
