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 trademarks ZSX, could be for baby NSX

While there have been many rumors dating back to 2008 about a mid-engined sports car from Honda, last year's report was provided the most detail about what seemed to be a scaled-down version of the NSX hybrid supercar. Honda may have added some fuel to the rumor-fire by recently filing a trademark application for "ZSX," reports Australia's Performance Drive. The trademark application was sent to the European Union Intellectual Property Office late last month and is obviously close to the NSX nomenclature. The Australian outlet also reports that an unnamed source within Honda claims the ZSX, whatever it may be, could be revealed as early as next year. The anonymous employee also claims that the ZSX will be offered as a coupe and a hard-top convertible variant, with both being powered by the automaker's 2.0-liter turbocharged four-cylinder engine from the Honda Civic Type R. Just like the NSX, the ZSX is rumored to get electric motors on the front and rear axles. Previous reports match the unnamed source's claims, as the ZSX was expected to be a replacement for the Honda S2000 that ended production in 2009. It now sounds like it'll be more of a mini-NSX, with rumors pointing towards one electric motor powering the rear wheels, while two motors would be on the front axle. Patents from last year, which are pictured above, match the rumors of a mid-engined sports car. The ZSX trademark is for Europe only as of right now, while the automaker's previous patents and trademarks included the US, as well. Only time will tell if "ZSX" really stands for a sports car, or if Honda actually goes through with its plans. Remember, Nissan ditched similar plans for a small rear-wheel-drive sports car recently.

2019 Acura NSX gets a refresh and an eye-catching new color

After two model years and about 1,000 deliveries to the U.S., Acura's given the 2019 model a few enhancements and a small price bump. The car debuted at The Quail, A Motorsport Gathering, during the festivities surrounding Pebble Beach. While there are no major powertrain changes, some new color options and a few chassis refinements will be appreciated by NSX fans. Let's start with the hardware, since this is a sports car, after all. Most important, there's new all-season rubber, still Continental SportContacts but the next version thereof — the 6. Acura claims better handling in all conditions, and the way tire technology has been improving, we'd believe it. The optional Pirelli Trofeo Rs remain — and remain highly recommended for anyone looking to sample the NSX on track, which is an exhilarating experience. Acura says the rest of the enhancements we'll mention shaved a full two seconds off the car's time at Suzuka, so take that for what it's worth. They consist of a 26 percent stiffer front sway bar and 19 percent stiffer rear bar; 21 percent stiffer rear toe link bushings; a 6 percent stiffer rear hub; and a new software calibration for the computer controlled bits: the SH-AWD system, magnetorheological dampers, electric power steering, and stability control systems. For a car as precisely engineered as the NSX, these are relatively significant improvements. Don't necessarily expect it to shave two seconds off your personal best lap time, but if you're highly attuned to the chassis dynamics, the '19 NSX should offer more precise and direct feedback to the driver. No need to be precisely attuned to the cosmetic changes — they're pretty obvious. Thermal Orange, a new exterior color, and the chrome beak-ectomy (it's not body colored) crown the exterior changes. Inside, the leather/Alcantara combo seats are now available in blue, and the full leather seats can be had in red. While the price for the 2019 model has gone up by $1,500, Acura says that there's now $4,700 in formerly optional equipment (power seats, satnav, premium audio, parking sensors, and sport pedals) included as standard equipment. That sounds like a good deal to us. If you want one, the order books are open and cars will be delivered starting in October. Related Video:
