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 prices hand-built TLX PMC Edition at $50,945

Acura unveiled the 2020 TLX PMC Edition sedan at this year's New York Auto Show along with the MDX PMC Edition Prototype. Both models adopt the same hand-finished build processes employed at Honda's Performance Manufacturing Center to create the Acura NSX. In the case of the sedan, that means a body-in-white pulled off the line at Honda's Marysville plant so that PMC technicians can install the interior, drivetrain, suspension, wiring harnesses, and electronics. After that, the TLX PMC undergoes the same quality control checks conducted on the NSX, including a dyno run and water leak test. The price: $50,945, which includes $1,995 for handling and destination. In addition to the craftsmanship, the sedan combines two options that normally cannot be combined, the A-Spec and Advance Packages. They install the 290-horsepower 3.5-liter V6 and Super Handling All-Wheel Drive, the A-Spec's stiffer dampers and quicker steering ratio, plus sharper exterior components like the restyled bumper, larger exhaust tips, and gloss black roof panel. Comfort features include heated and ventilated front sport seats, leather and Alcantara seating, black leather steering wheel, black headliner, surround-view camera, heated rear seats, and Acura's 10-speaker ELS Studio audio system. Cosmetic go-fast changes are seen in the red instrument cluster and red accent lighting. The whole package gets drenched in Valencia Red Pearl paint formerly exclusive to the NSX but making one special appearance here, the crimson infused with mica, metal flake and "nano pigments" for keener color. Black, 10-spoke, 19-inch wheels anchor the sedan to the road. The U.S. will see just 360 examples of the TLX PMC, each one numbered with a plaque on the dash. Deliveries to dealers begin this month — each sedan transported in a single-car carrier. The entire production run is scheduled to take six months, after which we're told Acura will begin working on the MDX PMC.

Honda slowing US production due to ports dispute

The labor dispute that idled 29 ports on the West Coast last the weekend, including Los Angeles and Long Beach, CA, is about to make its effects felt on the showroom floor, according to Reuters. Honda, Toyota and Subaru have been trying to work around the labor disagreement, cutting overtime and airlifting parts to factories, but Honda says parts shortages at plants in Indiana, Ohio and Ontario, Canada, are now severe enough to impede production. The lack of transmissions and some electronic components will slow output of the Honda Accord, Civic, and CR-V – as well as unnamed Acuras. The three affected factories will rework their production schedules from Feb. 16-23. The ports have reopened this week, and US Labor Secretary Tom Perez has flown to San Francisco to mediate a new agreement between the 20,000 dockworkers represented by the International Longshore and Warehouse Union and the Pacific Maritime Association, which represents the terminals and shipping companies. Talks have been going on for almost nine months and the issues aren't settled; meanwhile, the West Coast ports that handle half the nation's maritime cargo and 70 percent of cargo from Asia are putting all kinds of industries on the ropes, and it's estimated to cost the economy $2 billion a day.
