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.

Jay Leno finally gets his hands on the 2017 Acura NSX

It has been five years since Jay Leno and Jerry Seinfeld starred in a commercial about which one of them would get the first example of the new Acura NSX. After a long wait, they finally get a chance, but Leno is the first to check out the coupe in the latest video from Jay Leno's Garage. The denim-clad host spends over 30 minutes with lead designer Michelle Christensen and Ted Klaus, global development chief engineer, to get the full scoop on the hybrid supercar. Leno and Christensen get into the nitty-gritty about the design process for the latest NSX, and she points out her favorite parts of the finished product. She had quite a challenge creating the new supercar. Over the model's long gestation, every adjustment to the shape forced changes elsewhere to direct the airflow correctly, and then the decision to switch to a different engine configuration added even more time. Klaus focuses on the engineering side, like using the Ferrari 458 and original NSX as the major benchmarks for the new one. He also takes a ride with Leno, and the comedian even cracks a grin driving it. Leno doesn't usually show much emotion behind the wheel, so the little smirk is high praise from him. Carve out some time for a detailed walk-through about the 2017 NSX in the latest clip from Jay Leno's Garage. Related Video:

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.
