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.

Honda celebrates 30th anniversary of the NSX with a look back at how it began

In 1989, the baseball-loving Japanese dipped their bats in pine tar and came to the U.S. to take gigundous swings. That single year launched five legends: Lexus LS400, Infiniti Q45, Nissan 300ZX Twin Turbo, Mazda MX-5 Miata, and Acura NS-X concept. The Chicago Auto Show (!) hosted the global debuts of the Mazda and the Acura. While Mazda celebrates the bygones with the 30th Anniversary Miata, Acura's reminiscing with a look at how the NSX — a car Motor Trend described in 1990 as, "[The] best sports car the world has ever produced. Any time. Any place. Any price ..." — came to be. The development yearbook opened in 1984, a year after Honda returned to Formula One as an engine supplier for the Spirit team, and for the second Williams chassis in the last race of the season. For the first time in the automaker's history, Honda wanted to build a production car with the engine behind the cabin, one that would demonstrate Honda's engineering prowess and "deeply rooted racing spirit." The sports car would also serve as a halo for the not-yet-launched Acura brand. The engineering team built the first test vehicle in February 1984 on the bones of a first-generation Honda Jazz. After four years of formal development, Honda parked the NS-X Concept in a conference room at Chicago's Drake Hotel in February 1989. This is where the media would meet the red wonder before the public show-stand debut. The F-16 Fighting Falcon-inspired coupe was built on the world's first all-aluminum monocoque, and its SOHC V6 ran with titanium connecting rods. Before the press conference, then-Honda president Tadashi Kume got in the NS-X, started the engine, and revved to the 8,000-rpm redline — a noise felt by everyone in the adjacent conference room attending a Ford press conference. Honda's PR man at the time yelled, "Mr. Kume, stop it! They're gonna hear this!" When Kume got out, he asked Honda engineers present why they didn't put their new VTEC technology in the NS-X. (What's Japanese for, "Why didn't the VTEC kick in, yo?!") They told him VTEC had been created for four-cylinder engines. Kume told them to work on a V6 application. More suggestions came from journos who drove the early prototypes at Honda's Tochigi R&D Center, who said the NS-X "could use more power." The development team had grabbed the SOHC V6 from the Acura Legend for the NS-X concept, and it put out 160 horsepower in the luxury sedan.

2013 Acura ILX Hybrid

This Is Not The Acura You're Looking For
Mid-level luxury brands have always had to do a bit of leg work to distance themselves from their more common cousins. Thanks to generation after generation of pervasive badge engineering (much of it from the Big Three), buyers can't be blamed for looking at brands like Buick, Lincoln, Infiniti, Lexus and yes, Acura as tarted up versions of Chevrolet, Ford, Nissan, Toyota and Honda products. For much of its lifetime in the automotive landscape, however, Acura has excelled at putting distance between its offerings and that of its parent company thanks to cars with superior driving dynamics, quieter cabins and clean, attractive aesthetics.
Yes, outliers and dull spots can be found in the company's recent track record, but by and large, Acura products remain situated well above the Honda rabble. When the brand announced it was getting serious about the luxury small car game with the ILX, those of us with a set of the company's keys in our past couldn't help but envision an honest successor to the long-dead Integra. Turns out, that wasn't what Acura had in mind.
