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 planning sub-NSX S2000 successor

Nine years separated the arrival of the original Acura NSX and the Honda S2000. By that time, the NSX was closer to the end of its fifteen-year production cycle than it was to its beginning. The latest word has it that not only is Honda planning a successor to the S2000, but it's not about to wait that long after the new NSX arrives before it's rolled out.
While the S2000 was a front-mid-engined roadster, its successor will, according to the latest from Auto Express (which we are taking with a grain of salt), be a mid-engined coupe - closer, in other words, to the NSX than the S2000. Power would come from a more potent version of the 2.0-liter turbo four developed for the upcoming new Civic Type R, possibly as part of a hybrid system derived from Honda's upcoming Formula One powertain to develop over 400 horsepower.
Whether the new sports car would revive the S2000 nameplate, and whether it would wear the Honda or Acura badge in the United States, remain to be seen. As does its potential production site: while the previous S2000 was built at the same Takanezawa plant in Tochigi as the original NSX, the new NSX will be built at the new Performance Manufacturing Center in Marysville, Ohio. The new S660 roadster, meanwhile, is set to be assembled at the same Yachiyo plant in Yokkaichi as the original Honda Beat.

Honda trademarks 'CDX' nameplate

Less than two weeks ago, we discussed the possibility of an Acura-badged version of the sure-to-be popular Honda HR-V. Now, Acura has gone ahead and registered a new trademark that fits in perfectly with its two other crossovers, the RDX and MDX. Our friends at Auto Guide report the company has reserved the name "CDX" with the US Patent and Trademark Office, with the trademark covering "automobiles and their structural parts." While it's true that these kinds of trademarks are filed regularly, the timing in this case is indicative of something more than simply covering bases. After all, it seems very, very unlikely that we'd have comments from Acura on a premium version of the HR-V on February 5 and a trademark filing for a name that fits the brand's CUV nomenclature less than two weeks later, only for it to not go ahead and build an actual vehicle. Adding to that logic is the simple fact that the compact CUV market, both on the premium and mainstream level, is arguably the hottest in the auto industry right now, and it seems like a virtual guarantee that we'll see an HR-V wearing the Acura CDX name in the not-so-distant future. Should that come to pass, look for the CDX to challenge the near-premium Buick Encore, as well as a potential compact CUV from Infiniti.
