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.

Takata airbag victim urges consumers to head to the dealership

A man who lost an eye in a low speed collision due to faulty Takata airbags is urging the owners of cars with recalled parts to take their vehicles into a dealership, before it's too late. The public service announcement comes from ConsumerWatch.com. In a video, the consumer rights website gives factual information about the recall, and adds a personal plea from Corey Burdick. The Florida man lost an eye due to shrapnel from an exploding Takata airbag. The Orlando Sentinel reported that Burdick was traveling just 15 mph in his Honda Civic when he collided with another car. There were no other injuries caused by the crash, except for the loss of Burdick's eye. He filed a lawsuit against Honda and Takata this year. "I lost my eye because of a defective airbag. Take your car in today so this doesn't happen to you," Burdick said. ConsumerWatch.com told Honda and Acura owners not to drive their vehicles until the faulty airbags were replaced. Good advice, as the National Highway Traffic Safety Administration also recently advised owners of 2001-03 Hondas and Acuras to get their airbags replaced immediately. NHTSA says airbag inflators in those vehicles have up to a 50 percent chance of exploding in an accident. But replacing the airbags isn't as easy as simply going into the dealership. Many owners who take their cars in for replacement are finding out that new parts are in short supply as manufacturers grapple with the largest automotive recall in US history. Takata may not have enough replacements until 2019, CNN reported earlier this year. The problem is so pervasive that some brand new cars were found to be sitting on dealer lots with faulty airbags still in place months after the initial recall. Some cars have received replacements that were also faulty and now will require a second trip to the dealer. However, waiting is not an option for many owners. At least 13 people have been killed and over 100 injuries have been blamed on the airbags.

Acura NSX roadster finally on its way this year?

Autobild put together a slideshow forecasting various convertibles due to arrive from 2018 to 2023. The long-prophesied Acura NSX roadster graced the first slide, reportedly prepped for market launch later this year at a price of 200,000 euros. That's about 13,000 euros more spendy than the hardtop, a relative bargain. Don't call your Goldman private banker yet, though — that Autobild slide is likely as close as any of us will get to said roadster this year. We've been doing the hokey pokey with the droptop NSX for at least six years now. In 2012 an eager enthusiast corps thought a European patent might have revealed the convertible supercar, only to realize it was Acura protecting Tony Stark's screen gem in The Avengers (pictured). In 2016, Autocar reported that Honda viewed the NSX as a platform for experiment and tests of developing technology that "help [ Honda] understand where the brand is going." Those brand explorations meant Honda was "contemplating convertible, lightweight, non-hybrid and all-electric versions." In 2017, Internet snoopers happened on patent images for a droptop coupe first dubbed the "Baby NSX," then potentially the ZSX after more snooping dug up a trademarked name. Even though production plans for a "Small NSX" actually did exist, dated to before 2008, the Small NSX/BabyNSX/ZSX turned out to be the Honda Sports Vision GranTurismo entry when Honda couldn't make a business case for the genuine article. Here we are staring down the same wishing well. Last year Acura sold 137 NSXs in the U.S. through the end of Q1, and so far this year only 67 coupes found buyers in that time. We know the NSX is a halo car, but halos work to best effect when they're visible. So all we know now is that the talented hybrid would do well with any variant that would get it more visibility, of the top-down kind, the Type R kind, perhaps a road-legal, non-hybrid GT3 kind, or any other.
