OVERVIEW
In 1999, the 3.5RL received a more aggressively styled exterior
highlighted by a wider wheel stance and sharply chiseled body
character lines. Restyled exterior panels including the front and
rear bumpers, front chin spoiler, hood and grille, front fenders and
headlamps, rear combination lamp, trunk lid and rear license plate
garnish. Only the doors, rear quarter panel, outboard mirrors, roof
and glass were carried over from the previous model.
The 3.5RL body design is intended to impart a muscular stance and dynamic appearance while maintaining an enduring elegance and sophistication. The body of the 3.5RL is significantly taller than previous Acura luxury sedans, for improved headroom, especially in the rear seats, and a more substantial exterior appearance. The 3.5RL flanks are designed with high, relatively prominent "shoulder" lines, for a strong, masculine appearance, and the front grille/fender/bumper area is designed with a very clean, integrated configuration, giving a more massive, yet aerodynamically efficient look.
Refinements in aerodynamics resulted in a low coefficient of drag of 0.32 and a coefficient of lift of 0.102, resulting in greater high-speed stability and a very quiet, distraction-free interior environment.
PRECISE FIT AND FINISH
The RL is engineered and painstakingly 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.
VISIBILITY
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.
PAINT PROCESS AND CORROSION PROTECTION
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 special
scratch-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 personnel who work in the painting section of the factory wear
special contamination-free clothing while working and are 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.
CRYSTAL-CUT TAILLIGHT ASSEMBLY
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.
SIDE-MIRROR AIR DEFLECTORS
As an example of the extraordinary lengths taken to reduce wind
noise, the outside rearview mirrors are designed with a small wind
deflector, or spoiler, that directs oncoming air down and away from
the mirror assembly. By detaching the airflow under the mirror, the
deflector reduces the pressure gradient between the air rushing
around the mirror housing and the still air behind the mirror,
eliminating a "whistling" effect there that has been identified as a
cause of wind noise in the wind tunnel.
AUTO-OPEN POWER MOON ROOF
The RL includes an innovative power moon roof. The outer moon roof
panel first tilts up, for increased ventilation, and then opens
completely with one additional touch of the control button.
Energy-rejecting privacy glass is used, and the moon roof is
programmed to pause at the 130 mm position during closing to help
ensure passenger safety.
UNDER-CHASSIS SPOILER
A special spoiler, located immediately behind the front bumper, has
been developed to reduce airflow under the RL, thereby reducing the
high-pressure air under the front of the body and diverting it to
flow around the sides and over the top. 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.
