Acura's innovative all-wheel-drive system makes the RL easy to drive and helps keep its driver out of trouble. Called Super-Handling All-Wheel Drive, the system overdrives the outside rear wheel when motoring around corners, improving the handling balance and enhancing stability. Indeed, the RL is very stable in corners. We found it smoothes over minor driver errors, making us look and feel skillful. With this setup, the RL handles adverse weather exceptionally well, making it an excellent choice in Seattle, Denver, Chicago, Boston, or anywhere else that gets rain and snow. And while the 24-valve VTEC V6 provides plenty of punch, it's relatively efficient, netting an EPA-estimated 26 mpg Highway.
The RL offers the latest in navigation, communications, and collision-avoidance technology. Acura's navigation system is the best in the business. But the RL also offers AcuraLink traffic information in real time for 44 major cities: Clogged freeways are highlighted in red, flying freeways in green. This system works impressively well. We've put it to good use in avoiding traffic jams in Los Angeles.
The Acura RL can help drivers avoid pile-ups. The optional Collision Mitigation Braking System works with the Adaptive Cruise Control. Using radar, the system will alert the driver, pretension the seatbelts, and slam on the brakes when it senses an imminent impact. We tested this system in a controlled exercise and were very impressed with its ability to warn the driver and help avoid an accident or, in the worst case, reduce the severity of the impact.
For 2007, some of the features that used to be standard have been made optional to reduce the base price. Acura's satellite navigation system and Active Front Lighting, which aims the headlights into turns, are no longer standard.

Its muscular exterior styling is designed to suggest abundant power. In front, a dramatically sloping hood leads down to an aggressive front fascia with angular headlight treatments, Acura's signature five-sided grille, and distinctive lower air intake openings. The front end is smooth with nicely integrated bumpers and headlamps.
The rear is short to reduce aerodynamic drag and improve maneuverability. The rear three-quarter view is suggestive of a BMW 7 Series: Viewed from the side, the rear deck seems separated from the fenders.
High-intensity discharge headlights employ the Active Front Lighting System, which swivels the headlight beams up to 20 degrees in either direction when the steering wheel is turned, providing better visibility when cornering.
The cabin is finished in handsome leather with attractive stitching. Real wood is used sparingly and tastefully around the cabin on all but the base model, and it's not too shiny. Acura says it used the finest materials and exacting attention to detail in the interior design. It shows.
The Technology Package includes satellite navigation, which features voice recognition and a large, eight-inch display screen. Positioned at the top of the center stack, the display looks like it might be a touch screen, but it isn't. Instead, an interface dial functions something like a computer mouse to control all accessory functions. Positioned on the center stack, in front of the shifter, the dial is rotated like a knob and rocked like a joystick to select among function menus displayed on the screen. Pushing down on the knob selects the highlighted function. Functions controlled by the interface dial include the climate control system, audio, navigation, and the AcuraLink satellite communications system. This interface dial is similar in concept to that of BMW's controversial iDrive, but Acura added redundant buttons on the instrument panel and steering wheel for most of the commonly used functions and it's easier to use than BMW's system.
Acura's navigation systems are perennially among the best available and the RL's system works very well. In the past, we've praised them for their ease of operation, clear instructions, speedy route calculations, and absence of errors. As with all of these systems, there is a learning curve, however. You'll need to study the owner's manual and exercise patience before you can fully master the system and use it to its maximum advantage. Even then, trying to program navigation or other functions while driving is very dangerous; you should pull over, program your destination, get organized, then set out.
AcuraLink satellite communications delivers in-car traffic information in real time for 44 major cities, helping drivers avoid congested roads. It works best in the cities that have the infrastructure to support it, Los Angeles among them. Traffic flow is shown by color-coding the highways in three levels: light traffic is shown in green, normal traffic in yellow, slow traffic in red. The driver can view the map and choose the routes with the lightest traffic. The system uses live data from the highway departments using technology developed by XM Satellite Radio. It's easy to use, and commuters in cities with this technology will find it's well worth the cost of the package.
Bluetooth wireless technology allows hands-free dialing and communication and integrates compatible cell phones. As with other features, the Bluetooth cellphone setup can respond to voice commands. The Keyless Access System automatically unlocks the doors and allows the driver to start the car without having to dig the keyless remote out of pocket or purse.
The back seats are comfortable, though they don't offer quite as much space as some of the other cars in this class. The rear doors open wide, making it easier to get into and out of the back seats. A retractable rear sunshade filters the sun, nice for back-seat riders on bright days. Retractable rear headrests improve rearward visibility when people aren't back there.
The trunk is nicely finished and offers 13 cubic feet of space. The keyless access system prevents locking the key fob in the trunk.
Super-Handling All-Wheel Drive improves the handling of the RL considerably. SH-AWD distributes power not only between the front and rear wheels but also between the left and right rear wheels. The system controls this distribution of power precisely to enhance handling. Essentially, the system overdrives the outside rear wheel in corners to reduce the understeer that is inherent with all-wheel-drive layouts. As a result, the RL doesn't plow in corners. It simply motors around them.
We found this all-wheel-drive setup particularly helpful in tight corners where it keeps the nose of the car tucked in. The car seemed to respond well to throttle in the corners. The effects of overdriving one of the rear wheels is most noticeable at competition speeds, but the system improves handling feel even at a moderate pace. The RL just feels precise. It goes exactly where you want to go. The SH-AWD improves handling stability on dry or wet roads and the all-wheel drive improves traction and stability on snow and ice. The system is biased to the front. When cruising along, 70 percent of the engine's power goes to the front wheels, and 30 percent goes to the rear wheels. Stand on it, however, and up to 70 percent of the power goes to the rear wheels. That means little or no wheel spin when accelerating.
The driver can sense the front-wheel-drive bias of the RL. The rear-wheel-drive BMW 5 Series sedan feels livelier than the RL, making it more fun to drive. With its firmer suspension, the BMW feels more taut than the RL. However, the RL is easier to push to the limit in unfamiliar corners. So the RL would be an excellent choice if you had to choose a car to try to outrun bad guys over an unfamiliar mountain road, and that would be particularly true if the conditions were slippery or unpredictable. The styling isn't flashy enough for James Bond, however.
The 3.5-liter V6 engine generates plenty of acceleration performance and the RL responds quickly to jabs at the throttle. The V6 delivers impressive power, rated at 290 horsepower at 6200 rpm and 256 pound-feet of torque at 5000 rpm. Luxury cars with V8 engines offer more power and more low-end response, but the RL delivers solid performance. The Acura RL can accelerate from 0-60 mph in less than 7 seconds, so it can compete with a BMW 530i. Acura's 24-valve, single overhead-cam, aluminum VTEC V6 combines strong power with low emissions and reasonable fuel economy: The RL meets the government's stringent standards as a LEV2-ULEV Ultra-Low Emissions Vehicle and earns an EPA-estimated City/Highway 18/26 mpg.
The five-speed automatic transmission is excellent and aids the RL driving experience considerably. Shifting is crisp and quick but super-smooth, making the RL more responsive and more enjoyable. It seems to shift up early, but never seems to hunt for gears. The driver can shift manually using the shift lever (located on the center console) or with paddle shifters located on the steering wheel. Using this Sequential SportShift feature is fun, but we usually prefer to put the transmission in Drive and let it do the job it does so well, allowing us to concentrate on braking, steering and accelerating.
We found the brakes to be excellent, with a good, firm pedal. The brake system employs big, ventilated brake rotors with four-piston aluminum calipers in front, with ventilated discs in the rear. Electronic Brake-force Distribution (EBD) automatically adjusts
The Acura RL embraces the agile handling and quick acceleration performance of a sports sedan. It's easy to drive and helps keep its driver out of harm's way with the latest in all-wheel drive and active safety technology. Yet it rides nicely, coddles its occupants and exudes a sporty, luxurious ambience. Brakes and throttle are super smooth for comfortable driving in stop-and-go traffic. The Collision Mitigation Braking System helps drivers avoid pileups, while the real-time traffic system helps them avoid traffic jams. We recommend springing for the top-of-the-line, fully loaded model.
