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.

Acura introduces a sleeker self-driving test car

As we creep ever closer to an autonomous-car future, one thing is for certain, most of the driverless cars we see being tested look hideous thanks to all the sensors strapped to the roof. Today Acura introduced its second generation Automated Acura RLX Development Vehicle with updated sensors and a more pleasing aesthetic. Gone is the spinning LIDAR system replaced with a more compact and robust version of the light detection and ranging technology. It's also got updated RADAR, camera, GPS and higher performance GPUs and CPUs as well as what Acura is calling "more intelligent software algorithms to support more complex testing scenarios." Acura and its parent company Honda have been testing autonomous cars at its GoMentum Station in the Bay Area since last year with a specially outfitted RLX (shown in the video above with the spinning LIDAR system). This new car will replace that vehicle. This article by Roberto Baldwin originally ran on Engadget, the definitive guide to this connected life.

2016 Acura NSX: Everything there is to know [w/video]

The road to supercar stardom is littered with missteps. For every slam-dunk like the McLaren F1 and Ferrari F40, there are contenders that never quite reach their full potential – think Mercedes-Benz SLR McLaren and Jaguar XJ220. Fear of building a mediocre halo car is why automakers take costly detours like reverse-engineering a carbon fiber chassis when aluminum just won't do (we're looking at you, Lexus LFA), and it's often those second, third, and even fourth major redirects that can make the difference between has-been and hero. History has been kind to the late, great Acura NSX. Though its final years saw it lagging in power, ballooning in price and burdened by unsightly bubble headlamps, the NSX went to pasture in 2005 with a reputation for being an innovative, driver-focused ride that also happened to be practical enough for daily use. Despite its lofty aspirations and attainable price point, fifteen years of production saw just under 9,000 NSXs on the road, which begs the inevitable question: was Acura's mid-engine top dog too tame to be great, yet too ubiquitous to be exotic? Considering how the NSX redux has been worked (and re-worked as a stillborn front-engine V10 GT, only to return to a mid-engine layout), it's safe to say Acura is intent on securing supercar greatness. While the essential spirit of the original NSX program targeted the "New Sports Experimental" idea, Large Project Leader Ted Klaus says that Shigeru Uehara, the man responsible for the original NSX (and Honda S2000, among others) advised the US-based development team that they ought to be "... open-minded to doing things for the emotional benefit of the customer," and not come from a place that was "hyper rational." In other words, build a car that makes the heart skip a beat.

Gone is the naturally aspirated, transverse-mounted V6, replaced with a longitudinally mounted, turbocharged, dry-sump V6 that produces "north of 550 horsepower," according to Acura brass. As before, the internal combustion mill works with three electric motors to deliver power to all four wheels. Super Handling All-Wheel Drive, indeed – or, as Acura refers to it in this application, Sport Hybrid Super Handling All-Wheel Drive. Why the shift?
