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.

2002 Acura NSX fondly remembered in MotorWeek's retro clip

After a long wait, the new Acura NSX is finally here, but so far the latest generation is proving polarizing among enthusiasts. Whether it's complaints about the styling, the nearly $200,000 price, or the switch to hybrid power, nearly everyone seems to have a critique about the new sports coupe. That said, nostalgia for the original NSX remains strong, and the latest MotorWeek Retro Review of the 2002 model reminds us how different the new NSX is from the original. The 2002 model year marked the NSX's transition from pop-up headlights to fixed units, and it also features less noticeable styling tweaks along the sides and at the rear. Behind the driver, there is a 3.2-liter V6 with 290 horsepower and 224 pound-feet of torque, and it routes through a six-speed manual to get the coupe to 60 miles per hour in five seconds. There was also an available automatic gearbox with a 3.0-liter V6 that made 252 hp and 210 lb-ft. MotorWeek's review lavishes praise on the way the NSX drives by calling it "almost unflappable" and saying "body roll was almost nonexistent." With traction control off, the coupe changes character by becoming more twitchy and requiring that drivers use a careful balance of throttle and steering. Sounds perfect. Easily the best part of the review is when MotorWeek claims that a second-generation NSX is on the way. Over a decade later, that vehicle is finally, almost, on sale. Will it live up to the red-hot NSX standard of yore? We're about to find out. If you need any more nostalgia, the show previously remembered the '91 NSX, too. Related Video:

Acura RLX will die after 2020 model year

Only Acura knows why its flagship RLX sedan is still on sale; every year that we had occasion to remember the RLX — which wasn't every year — seemed like a good year to let the car die peacefully. Automotive News reports the deed is finally done, or rather, will be at the end of 2020, when Acura discontinues the model that started with the RL in 1996. Honda told U.S. dealers yesterday that in other markets like Japan, the four-door will continue to sell as the Honda Legend. Honda's comment to AN included, "With SUVs leading the luxury market, the highly successful RDX and MDX now serve as volume leaders of the Acura brand," and, "We will further strengthen our sports sedans, consistent with the performance-focused direction we have been taking Acura over the past four years." Speaking of the devil, the RL and RLX — and Acura as a brand — never got out from under the weight of the Legend sedan, that ancestor being the second of Acura's three albatrosses after the original NSX and the Integra. The RL never equaled the Legend's worst year of U.S. sales. The RLX, a combination of arousing performance under anodyne styling costing premium German money, might have performed the same feat viz the RL, but the RL sold less than 5,000 units here for the last five years of its life. The RLX has only exceeded 5,000 sales once, in 2013. Last year, 1,019 units found buyers.  Acura's focus now is the NSX halo and the continuing overhaul of the volume lineup. The new RDX is going great guns, the new MDX crossover is due this year. The slightly larger and Type S concept-inspired TLX sedan is expected to be another gift to 2020, followed by the return of a bona fide Type S next year, after which the ILX compact sedan gets its turn. Last year was the first time in five years the TLX dipped below 30,000 sales in the U.S., impressively steady going for a segment with shocking attrition. Although the demise of the RLX gives up on the aspiration for a big luxury flagship, the coming TLX should help us forget what the RLX represented. If we hadn't already.
