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.

Production Acura NSX spied getting sharper on the 'Ring

Acura hasn't been shy about trotting out the concept version of its upcoming NSX hybrid supercar - we've seen it colorized on Facebook, wearing Super GT drag and running wrapped at Mid Ohio - but until now, we've missed seeing the production version at all. Thankfully, our boys in the field have been diligently camped out by the Nürburgring, just the place for Acura engineers to get the NSX shaken down and ready for the public.
The first thing you'll likely notice (and no doubt appreciate) is that Acura is staying very true to the concept car. The same wind-tunnel-carved wedge shape is in evidence in the car's silhouette, and details like aggressively scalloped engine vents behind the cabin have made it through unscathed.
We do notice that there are some vertical elements at the bottom of the front fascia/grille that appear to be revised, and the mirrors are considerably less slinky than those of the concept car. Still, by and large, we're seeing a direct translation from show stand to real life here.

Junkyard Gem: 1992 Acura Vigor

Honda was the first of the Japanese car manufacturers to bring a separate luxury brand to the United States, with the (Civic-derived) Integra and (Rover-related) Legend appearing as 1986 models. By the early 1990s, Infiniti and Lexus had muscled in with their own gadget-laden luxury machines, with even Mitsubishi and Mazda offering legitimate competition for the two Acura models. Something had to be done, in the viewpoint of Soichiro Honda, and so the NSX sports car was introduced as a 1991 model, followed by the Vigor luxury sedan the following year. Here's one of those rare first-year Vigors, found in a Denver self-service boneyard recently. The idea behind the Vigor (which, like the Integra, Legend and NSX, was badged as a Honda in its homeland) was that it would squeeze in between the Integra and the Legend and steal some sales from the Lexus ES 250 as well as European machinery. The Vigor was a front-wheel-drive car, but its engine was mounted longitudinally and angled to clear the hood. The differential sat directly beneath the engine and received power via a tortured maze of shafts. The reason for all this powertrain complexity was the fact that the Vigor's engine was a SOHC straight-five that wouldn't fit the engine compartment using Honda's usual transverse mounting (though both Daewoo and Volvo managed the feat with straight-six engines later on). The U.S.-market Vigor's 2.5-liter five-banger was rated at 176 horsepower and 170 pound-feet. The base transmission was a five-speed manual, but this car has the optional $750 four-speed automatic ($1,696 in 2024 dollars). This car is the cheaper Vigor LS model, so its MSRP was $24,999 ($56,539 after inflation). You could get a slightly smaller but still feature-laden '92 Honda Accord EX for just $20,175 ($45,629 now), though, and the cushier (though less nimble) Lexus ES 250 started at just $21,300 ($48,173 in today's money). American car shoppers just couldn't figure out the Vigor, and sales were weak. 1994 was the final year for the Vigor, and the TL replaced it beginning as a 1996 model. This one drove just over 160,000 miles during its life. Don't think of it as a drive to work. Think of it as a 30-minute vacation. If you get a German luxury sedan instead of a Vigor, you'll be sorry! I miss you… S. As was nearly always the case during the 1980s and 1990s, the JDM commercials were more fun.
