2020 Acura NSX Suspension Deep Dive

The Acura NSX has been a special car as long as I’ve been in the business. The first one came out in 1990, the same year I started my career in automotive engineering. I vividly remember driving one briefly back then when we brought one in for benchmarking. I'd drive it again 22 years later when my previous employer bought a used 1991 example for a long-term test. Reader interest was sky-high and the car was still gorgeous, but the march of time and automotive engineering had clearly left it behind. Then, in 2016, a second-generation NSX emerged, and it was packed with bleeding-edge thinking. It has a 3.5-liter twin-turbo V6, but this new NSX is a hybrid with an electric motor-generator sandwiched between the engine and its nine-speed DCT transmission. Two more electric motors – one for each wheel – power the front axle. There they can add traction, regenerate electricity under braking and dole out hyper-accurate levels of torque vectoring. The carÂ’s tire package was changed from Continental SportContact 5 to SportContact 6 tires in 2019, and numerous suspension re-tuning tweaks came along with them. The result is a lively and well-balanced car that is relentless when driven hard and a pussycat around town. LetÂ’s see what theyÂ’ve got going on under there.   At first glance the 2020 Acura NSX appears to have dual wishbone front suspension. But we canÂ’t tell for sure because that big two-piece brake rotor is in the way. The coil-over shock looks obvious, but a few odd details are apparent even from here.   This view also seems to indicate double wishbone suspension. But the pivot axis (green arrow) between the upper and lower ball joints looks wrong – itÂ’s far too vertical. WeÂ’re missing something. But I would be remiss if I failed to point out a few other things before we moved on. For one, the front drive axle confirms this to be an all-wheel-drive machine. Second, the forged aluminum damper mounting fork (yellow) that envelops the axle is mounted to the lower arm about 75% out from the armÂ’s inner pivot. The spring and damper motion ratio would be 0.75-to-1 relative to wheel movement, with a tiny reduction due to its lean angle. Lastly, just look at the huge cast aluminum upright (white). Beautiful. Normally these are called hub carriers or steering knuckles, and I use the terms interchangeably. But the motorsports-derived term upright is normally applied when the piece is tall and, well, upright like this one.   This explains everything.

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.
