2019 Acura RDX infotainment first impressions | A first step into the touch pad world

One of the greatest design challenges in the modern automotive industry is an infotainment system that provides loads of capabilities, but is also easy-to-use and not overly distracting. Touch screens have been leading the way as the favored option, but Acura is trying a new design that relies on a touch pad with some unique tweaks to separate it from similar systems, such as those seen in competing Lexus models. And we got to try it out in the first production application, the 2019 Acura RDX compact crossover. The key feature of the touch pad is its one-to-one position functionality. What that means is that, if you have a grid of function buttons on the screen, tapping on, say, the upper left corner of the pad will highlight the button in the same area on the screen. And if you were to take your finger off the pad and tap in the opposite corner, that section of the screen would immediately be highlighted. You don't have to slide your finger across the pad to reach selections if you don't want to, and you don't have to slide back from the last function you highlighted. It basically does away with the need to move a cursor around like you would on a laptop with its mouse pad. In practice, it's a little odd to use at first because we mentally connect using a touch pad with the traditional cursor interface of the laptops we use day in and day out. As such, we forgot that we didn't have to scan the screen for the cursor every time we needed to select something. But once we remembered we could skip that, we found it quick and easy to drop our finger down and slide to our preferred function quickly. We could occasionally even pick something on the corners without having to slide at all. This is partly because Acura designed the interface to work with this pad. A representative from Acura's R&D center explained that they tried to put common functions on those corners because they're easy to reach without looking or thinking much. Another bonus to this system is that you don't immediately go to the function the second you press the pad. Instead, the feature is highlighted and still needs a physical click to enter. This is enormously helpful, since it virtually eliminates the chance of going to the wrong selection because you hit a bump or just got lazy with finger placement. Instead, you can get your finger in the right spot and then commit with a button press.

2019 Acura RDX crossover gets turbocharged power, A-Spec version

NEW YORK — Calling the RDX that Acura showed at this year's Detroit Auto Show a "concept" was stretching that term to the limits of credulity. The production version of the 2019 RDX is here, and this turbocharged crossover with available AWD looks darn near identical. While it offers all-wheel drive like its Lexus NX and Audi Q3 competitors, Acura's next-generation SH-AWD should be a serious selling point. Let's cover that "Super Handling All-Wheel Drive" system for a moment. It takes power from the 2.0-liter, 272 horsepower and 280 pound-feet of torque engine and routes it up to 70 percent rearward, and there's real torque vectoring (rather than brake-based faux vectoring) to shift 100 percent of that rear axle power to either wheel. The broad strokes are similar to the outgoing model's system, but there's much more available rear power bias — in the 2016 model, up to 40 percent could be sent to the rear. And that was up from 25 percent for pre-2016 models. The takeaway is that the RDX should handle a lot better on both dry and slippery pavement, and feel a bit sportier doing it. A new engine may help as well. The outgoing 3.5-liter V6 is replaced by a turbocharged four-cylinder, almost certainly related to the unit in the Accord and Civic Type R, and tuned somewhere in between those cars (252 and 306 horsepower, respectively). We expect the new engine to be lighter than the old V6, and less weight off the front end should improve steering feel and handling. For those keeping track, the new engine is down 7 horsepower but up 28 pound-feet in torque, and thanks to turbocharging the torque band starts down low and is relatively flat, so more oomph from a stop and on through the rev range. The six-speed automatic is gone, replaced by a 10-speed automatic. Most of its competitors use six- or eight-speed units, so that'll be a marketing focus. As you'd expect, the individual ratios are closer-spaced but the total ratio spread is, according to Acura, 62 percent wider than the outgoing automatic. There are steering-wheel-mounted paddles if you'd like to shift yourself. Since the styling is very much a lightly retouched Prototype RDX from the Detroit show, it's nice to be able to give a sense of the new car's proportions with hard numbers. First of all, it's riding on a 2.6-inch longer wheelbase. Overall length is 187 inches, up from 184.4, and width is unspecified.

New TLX A-Spec leads Acura's three-car Pike's Peak attack

Once again, Acura is headed to Pikes Peak for the hillclimb on June 25 with a small group of machines. This year the focus is on the TLX, with two vehicles bearing the sedan's name and shape. The two cars are very different, though, and will compete in two different classes. The first is the TLX A-Spec. This started life as a production TLX, but the 3.5-liter V6 has been reworked with pistons, rods, camshafts, and a valvetrain from Acura's TLX GT race car. The engine also has a turbocharger, which helps the V6 make an impressive 500 horsepower. All those ponies go to the front wheels through a limited-slip differential. In addition to the powertrain upgrades, the interior has been gutted, and a big wing and front splitter fitted. The A-Spec will compete in the Pikes Peak exhibition class. The other TLX is a TLX GT. This is the type of car from which the A-Spec borrows engine components, but not the TLX GT's twin-turbocharger system. TLX GTs have already been competing in motorsports, specifically in the Pirelli World Challenge. Acura did make some changes to this car for Pikes Peak, though. The suspension and engine computer have been tweaked, gear ratios shortened, and additional aerodynamic bits added for more downforce. The TLX GT will compete in the open class. Despite the focus on the TLX, Acura is still bringing an NSX to the hill climb. This car is similar to the one that raced in the Time Attack 1 class last year, but has some changes for the Time Attack 2 class. Most notable of these changes are the massive rear wing and front splitter. According to Acura, these aerodynamic aids were based on those used for the NSX GT3 race car. Acura also reduced weight, changed the tuning on the engine computer, and fitted sticky R-compound tires.
