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.

Acura NSX electric revival? 'I would bet on it'

This year marks the end of the Acura NSX as we know it. Its swan song, the 600-horsepower 2022 Type S, saw only 300 made for the U.S. market, and all of them sold out in 24 hours. It's barely disappeared over the horizon, but Acura's V.P. and brand officer is already previewing the NSX's third act. Speaking with Nikkei Asia, Jon Ikeda was asked whether a third generation NSX was forthcoming. "I would bet on it," he said. Ikeda also predicted that if the wager lands in his favor, "it's going to be [all-]electric." This falls in line with statements Ikeda made a year ago. At the time, he explained that the NSX emerges when parent company Honda wants to make a statement: The first generation was Honda's vision for an F1-derived petrol-powered supercar; the second generation arrived as an affordable hybrid halo car in the age of gasoline-electrics. He didn't elaborate on the third generation's powertrain back then, but this time Ikeda was more adamant about electric power.  Part of Ikeda's certainty, the article states, comes from global CEO Toshihiro Mibe's commitment to electrify Honda's lineup. Soon after taking the top job in April 2021, Mibe announced plans to convert Honda's entire lineup to EVs and hydrogen fuel cell vehicles by 2040. As for what kind of car an electric NSX would be, Ikeda has some ideas. "It won't be just about straight lines," he told Nikkei Asia. Blistering acceleration is already common in the electric supercar world, so Acura would need to bring something novel to the table. Ikeda wants the NSX to be a technological showcase for ultimate handling as well, something the outgoing NSX did with its driver-focused Super Handling AWD system.  We've long bemoaned how the new breed of electrified supercars have incredible specs on paper, but somehow don't feel as engaging to drive. That's a niche Acura could fill. In the often contentious give and take between American Honda and Honda Motor's engineering departments, the Japan mothership tends to win out. However, these days Honda barely sells anything beyond kei cars in Japan. It's up to leaders like Ikeda and those who understand the U.S. market to drag the company toward the performance-minded engineering philosophies Old Man Soichiro founded his business on.

Honda tags Civic, Accord, HR-V, Fit and more in fuel pump recall

American Honda Motor Company's recent issues with fuel pumps continue, as a new recall affects a large number of Honda and Acura vehicles from the 2018-2020 model years. The recall covers a total of 136,057 vehicles, including select 2018-2019 Acura NSX, 2019 Acura RDX, RLX, and RLX Sport Hybrid models, as well as 2018-2019 Honda Accords, Civic Hatchbacks, Civic Type Rs, HR-Vs, 2019-2020 Insights, and 2019 Fits.  National Highway Traffic Safety Administration campaign No. 20V314000, published May 28, 2020, states that the low-pressure fuel pump inside the fuel tanks of the aforementioned vehicles could falter or completely fail. Should the low-pressure fuel pump fail, the car could stall, regardless of its state of motion. Recall documents reveal fuel pump might fail due to swelling of the fuel pump motor impeller, which would cause the pump to seize. This issue is the result of a problem with how the parts were manufactured. These "lower density impellers" were "exposed to production solvent drying for longer periods of time." This caused some impellers to have surface cracking, which resulted in "excessive fuel absorption," which warps the impellers. Here's a breakdown of how many vehicles of each type were potentially affected:  2018-2019 Acura NSX: 146 2019 Acura RDX: 34,405 2019 RLX: 124 2019 RLX Sport Hybrid: 206 2018-2019 Honda Accord: 11,227 2018-2019 Civic Hatchback: 24,235 2018-2019 Civic Type R: 1,785 2018-2019 HR-V: 39,676 2019-2020 Insight: 14,959 2019 Fit: 9,294 Honda will notify owners to schedule an appointment with local dealerships. The fuel pump assembly on all affected vehicles will be replaced for free. For more information, visit NHTSA. Related Video:
