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.

Junkyard Gem: 1987 Acura Legend Sedan

Honda beat Toyota and Nissan in the race to bring a luxury marque to North America, introducing us to the Acura brand for the 1986 model year. Acura shoppers could buy a luxed-up, more powerful Civic (the Integra) that year, while the real high-rollers went for a smooth-looking, V6-powered luxury sedan co-developed by Rover and Honda: the Legend. That was quite a leap for a company that had been selling tiny cars with two-cylinder motorcycle engines just 15 years earlier, but the 1973-1985 period had been spectacularly good times for Honda. The early Legend sold very well in California, and that's where I found this high-mile '87 a couple of months back. While the Legend had the same underlying chassis structure and engine family as the Rover 800 (known as the Sterling in North America), the Honda-grade build quality and non-Lucas electrical components of the Legend meant that it outlasted its Rover cousins by decades and hundreds of thousands of miles. This one didn't quite make it to 300,000 miles, but 281,032 miles blows away the readings I see on most 1980s junkyard cars not made by Mercedes-Benz. It's hard to imagine a prestigious luxury sedan with three pedals these days, but plenty of the early Legends were sold here with the five-speed manual transmission. Starting in the early 1990s, though, nearly all U.S.-market Legends had slushboxes (though the manual could be had all the way through the final Legends of 1995). Every Legend ever made came with a V6 engine. This car has a 2.5-liter DOHC rated at 151 horsepower, while the 1987 Legend coupe got a 2.7 making 161 horses. Other than the worn-out front seats, the interior in this car looked fairly decent when it arrived in its final parking space. Most super-high-mile cars I see in junkyards aren't very trashed-looking, presumably due to owners who took good care of them for decades (I do see the occasional exception to this rule, of course). The body shows no rust, as you'd expect in California, but the paint hasn't fared so well over its 33 years. It's the performance sedan making European automakers uncomfortable. Unlike many of the wild Japanese-market car ads of the 1980s, Honda pitched the JDM Legend in a most dignified manner.
