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.

2022 Acura NSX Type S is revealed as the most powerful NSX ever

The 2022 Acura NSX Type S is here, and it's the most impressive NSX the company has created. It now makes 600 horsepower and 492 pound-feet of torque, increases of 27 ponies and 16 pound-feet. But that's only the tip of the many little changes Acura has done to make this the ultimate NSX. Gaining that extra power involved quite a few little changes. The engine now gets larger turbochargers borrowed from the GT3 race car. The various intakes have been changed for improved cooling and airflow. The main front grille has been enlarged to allow more air into the radiators, and the outboard grilles now feature ducting for air curtains that help direct air to the side intakes. Those intakes feed more efficient intercoolers. The batteries even feature greater capacity. Power isn't the only area to receive upgrades. The Type S gets a carbon fiber roof for slightly less weight and a lower center of gravity. The aerodynamics have been tweaked with a new carbon fiber splitter, side skirts, rear spoiler and a GT3 race car-inspired rear diffuser, all of which help with downforce. The adjustable suspension, all-wheel-drive system and transmission have all been retuned for sportier driving. The latter shifts faster now and has a Rapid Downshift mode that allows you to shift to the lowest possible gear with one half-second paddle pull. Even the tires are stickier Pirelli P-Zeroes designed specifically for the NSX Type S. All of these improvements mean that the Type S is a full two seconds faster around Suzuka than a regular NSX. And if you need just that little bit more in the performance department, there is a Lightweight Package. It costs an extra $13,000 and adds carbon ceramic brakes, a carbon fiber engine cover and carbon fiber interior parts. Total weight savings is 58 pounds. Acura did pay some attention to styling, too. On top of the more aggressive aerodynamic bits, the grille has a new shape that has hints of the corporate pentagonal grille. The grille mesh is even steel instead of plastic now. The lights get dark lenses, and all the badging, mirrors and door handles are finished in black. Type S decals adorn the rear fenders. Inside, there's an Alcantara headliner and NSX and Type S logos embroidered in the seats and dashboard. One of the cars in the gallery at top is painted in an exclusive Gotham Gray matte metallic color, which will only be applied to 70 cars.

Acura NSX will use Cosworth block, plus other neat tidbits

The blue NSX you see here was built just two weeks ago. Prototype number six, it rolled off Acura's newest assembly line in Ohio and was rushed out to the Monterey peninsula for various car week activities. We had a chance to sit down with several members of the NSX team to discuss the car, the long road from concept to production, and some interesting details. Below are some choice bits from our conversations. Acura is pretty proud of the fact that NSX version 2.0 was designed and is being built in the US. The new assembly line, called the Performance Manufacturing Center, is in Honda's hometown of Marysville, Ohio. While the line is brand new, the building has seen many uses over its lifetime, most recently as a warehouse facility. PMC staff numbers about 100, with 60 technical and 40 non-technical associates. The car uses parts sourced globally, and one of those sources is Cosworth. The engine blocks and heads come from the English firm and get assembled into twin-turbo powerhouses at Honda's nearby Anna, Ohio, engine plant. The Cosworth name is rarely associated with a bad engine, so we were geeked to hear the NSX's 550-plus-horsepower hybrid powertrain has good genes. Acura hasn't decided how many cars will come to the US each year, but supplies will be limited. We're told there is a total figure for global sales – basically anywhere Honda and Acura vehicles are sold – but they're not ready to divulge that number. Dealer allocation is also yet to be sorted out, although we're told that any dealer that has the necessary tools and equipment to service the new NSX will be able to sell them. Acura currently has 272 US dealers. The switch from the transverse engine originally planned to a longitudinal twin-turbo engine threw everyone involved for a loop. The designers had to lengthen their nearly finalized design, and the engineers working on the production process had to revise or redo much of their work. Though we've been waiting a while for the car since the concept first surfaced in 2012, it's pretty amazing to think that the car was engineered one and a half times and a new factory was built in about three years. But yeah, it's delayed, with series production now set to commence in the spring of 2016. One result of the switch to a longitudinal engine is a transmission hump in the cargo area aft of the engine. The hold is still sized to fit a bag of golf clubs, though it will be a tight fit.
