The RL's powerful V6 provides ample acceleration. We timed 0-60 mph at a brisk 7.0 sec. That's almost on par with some V8 rivals, but RL can't quite match their highway passing punch. Transmission shifts smoothly, responds quickly to convenient manual-shift paddles. Test RLs averaged 17.0 mpg in mixed city/highway use that included gas-eating performance tests, 21.0 mpg with more highway driving. Acura recommends premium-grade fuel. Ride quality is remarkably supple even for a sports-luxury sedan. Only the sharpest bumps filter through. Handling is confidence-inspiring, with accurate steering, firm suspension, strong brakes, and traction-enhancing SH-AWD. The last behaves like other AWD setups in normal driving, but feels a touch more stable in aggressive maneuvers. The 2006 Technology Package's radar-based cruise control and auto-braking systems impressed us in brief demo runs and seem to be worthy safety aids. Inside, there are legible gauges and mostly sensible controls. But the center dash is awash in buttons, many duplicating functions accessible from a "master" knob for display on the large, clear dashboard screen; sorting it all out takes patience. At least the responsive, accurate voice control simplifies navigation use. Real time accident/traffic info is a boon for commuting, and the stereo can play DVD Audio discs. Cabin decor and assembly are top-notch. The RL is one of the quietest cars around--engine, road and wind noise are all impressively hushed. There is ample head and leg room in front. Seats are all-day comfortable and supportive in spirited cornering. Some shorter drivers may feel a bit "buried," but ample seat adjustments, tilt/telescope steering wheel help compensate. The rear seat area has enough head clearance for all but the very tall. Rear knee room and toe space are fine unless front seats are moved well aft. The bench seat is unusually supportive, but center floor hump compromises three-abreast comfort. The RL's overall cargo space is average. The wide trunk extends well forward, but lacks height for really big cargo. Sickle-shape trunklid hinges are covered, but eat up space; most rivals have compact strut-type hinges. The rear seatback has small pass-through but doesn't fold.

Value for the Money
The 2005-06 RL boasts a sporty demeanor, smart engineering, standard all-wheel drive, and Acura's reputation for reliability and resale value. Other premium midsize rivals offer V8 power and higher nameplate prestige, but the RL is still an excellent value.
