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.

Honda insiders push for Acura NSX Type R sans hybrid tech

With 500 horsepower on tap from a sophisticated hybrid powertrain, there's plenty to love about the new Acura NSX. If the more performance-oriented elements within the Japanese automaker get their way, it could get even better. Speaking with one of the NSX project's chief engineers Nick Robinson at the launch of the new supercar, Autocar reports that there's an effort underway to develop an NSX Type R. Following a much-loved formula, the more extreme variant would pack even more power than the existing version, unburdened by excess weight. A big part of the targeted weight savings would come from ditching some of the heavier components from the hybrid system. The electric motor at the rear could stay to serve as alternator, starter motor, and flywheel. But the electric motors at the front would go, helping to shed a few hundred pounds. Throw in some lightweight materials and we'd be looking at a considerable weight reduction. It could even integrate some active aerodynamic elements that were excluded from the NSX on the road to production. Though the project may still be a ways off from getting the green light, but Robinson and some of his colleagues are working on prototypes ostensibly to make the case. He and his brother James (a powertrain engineer at Honda) will be driving a pair of NSXs at Pikes Peak this year – one that's as close to showroom stock as the regulations will allow, but the other will be closer to what they have in mind for a Type R. It'll ditch the hybrid system and put an electric compressor in its place to eliminate any turbo lag and produce even more power than the existing model. Now if they can only get the go-ahead from the higher-ups at Honda.

NSX, S660, and a 4-motor CR-Z EV that goes like hell

AutoblogGreen Editor-in-Chief Sebastian Blanco was my road dog while visiting Honda's R&D center in Tochigi. Over the course of a long day of briefings, driving demonstrations, and a variety of strange-flavored candies, we saw quite a lot of what the company is planning for the next generation and beyond. Of course, Sebastian and I see the world through very different eyes. So, while he was busy getting details about the FCV Clarity successor, and asking tough questions about electrification (in other words, the important stuff), I was fixating on a tiny, two-seat sports car that will never come to America. Oh, there was an NSX, too. Honda's pre-Tokyo Motor Show meeting really did have plenty to offer for all kinds of auto enthusiasts, be they focused on fast driving or environmentally friendly powertrains. Seb's attendance let me focus on the stuff that's great for the former, while he wrote up high points of the latter. View 15 Photos S660 I joke about salivating over the S660, but honestly I was at least as excited to take a few laps in Honda's Beat encore, as I was to sample the Acura supercar. Conditions for the test drive weren't ideal, however. Two laps of a four-kilometer banked oval is not exactly nirvana for a 1,800-pound, 63-horsepower roadster. Still, I folded all six feet and five inches of my body behind the tiny wheel determined to wring it out. The immersion of the driving experience was enough to make it feel fast, at least. I shifted up just before redline in first gear with the last quarter of the pit lane rollout lane still in front of me. The 658cc inline-three buzzed like a mad thing behind my ear, vastly more stirring than you'd expect while traveling about 30 miles per hour. The S660 is limited to just around 87 mph, but the immersion of the driving experience (note: I was over the windscreen from the forehead up) was enough to make it feel fast, at least. Even after just a few laps, and precious little steering, I could tell that everything I grew up loving about Honda was in play here. The six-speed manual offered tight, quick throws, the engine seemed happiest over 5,000 rpm, and the car moved over the earth with direct action and a feeling of lightness. Sure proof that you don't need high performance – the S600 runs to 60 mph in about 13 seconds – to build a driver's car. I could have used 200 miles more, and some mountain roads, to really enjoy the roadster (though I would have wanted a hat).
