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.

MotorWeek remembers retro icons, Supra and NSX

It's easy to poke a joke here and there about John Davis, the long-time host of MotorWeek. His voice is so monotonous that, from time to time, if you closed your eyes, you may think it's generated via a computer. But you have to give him and the rest of the show a lot of credit. The program has been on the air for decades, giving people direct, straight-down-the middle automotive reviews.
MotorWeek's massive back catalog of reviews are slowly making their way onto YouTube, and they provide a fascinating chance to look back on how performance cars rank against their contemporaries from back in the day. Two recent additions include the show's old looks at the 1986 Toyota Supra, the dawn of the third-generation model, and the now-iconic 1991 Acura NSX.
Both reviews are interesting in their own way. These days you hear nary a negative word about the original NSX, but MotorWeek isn't afraid to point out a few flaws. And the Supra really shows the progress of suspension tuning in the intervening decades because it has some serious body roll in the corners. Scroll down to check out both videos and get a blast from the automotive past.

Acura Integra's racing hopes hinge on Honda

The 2023 Integra has mostly failed to create the stir from long-time enthusiasts that Acura had hoped it would. However, all is not lost; Acura could perhaps regain some street cred if they took the Integra racing, like they did with the Integras of the 80s and 90s. Brand head Jon Ikeda wants to take the 'Teg to the track, but it all depends on whether the leadership at the American Honda mothership permits it. "We want to race this thing, but maybe the Honda PR and marketing guys might have different ideas," Ikeda told Road & Track. That's because the Integra is largely a 2022 Civic Si with a hatchback form factor and new sheetmetal. Honda already sells a Civic Type R race car in several tunes for various classes in the TC America touring car series. That was based on previous-generation Civic, but in all likelihood will continue the program with the latest gen. A racing Integra, then, would seem redundant. On the other hand, Acura has been highly active in motorsports, from 24 Hours of Daytona-winning IMSA DPi prototypes to NSX GT3 race cars to Pikes Peak hill-climbers. Even Honda's F1 cars were re-branded with Acura livery at last month's U.S. Grand Prix in Austin. And it's not like the Integra doesn't have a long history in motorsports. The nameplate as competed in various North American series from SCCA Pro Rally to IMSA sedan to the Import Drag Racing Championships. Perhaps the most well-known Acura Integras to race, though, were Peter Cunningham's white and neon orange RealTime Racing Type Rs that dominated the SpeedVision World Challenge championships around Y2K. Ikeda has said before that he wants Acura to be the performance brand of Honda, and a rumored Integra Type S is in the works with a more potent engine, possibly a version of the upcoming Civic Type R's mill. "We're the performance division of Honda," Ikeda emphasized to R&T, "So we're not going to shy away from Honda, you know? We're going to just have a little bit more fun." While an admirable goal, the brand will struggle if it's merely the performance arm of Honda. It has to be about performance cars, period. That was part of Acura's magic in the 90s; it offered products that, while sharing components with Honda, were distinct and had their own personalities. The Integra was Civic-based, but it had noticeably better handling, more power, and unique design.
