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.

Snapshots from Acura NSX prototype run at Mid-Ohio

Acura's achingly slow showing of the new, hybrid NSX saw yet another step yesterday, as we reported late last week. A powder-blue prototype ran ahead of the open-wheelers at the Honda Indy 200 at the Mid-Ohio Sports Car Course. Why show the NSX Prototype at Mid-Ohio? Honda's Ohio research and development center, which has taken the lead on NSX development, is just 60 miles from the track. And as race sponsor, Honda must have figured it would give the spectators a glimpse of the new supercar it's been teasing for the better part of a decade.
With a planned launch in 2015 (special emphasis on the "planned" part, considering the NSX's history), the NSX Prototype shown here sports graphics that "speak to Acura's intention to go racing with the new NSX." That's great news for fans of endurance racing, although it remains to be seen when a motorsports program for the new NSX will get off the ground.
Take a look at the fresh gallery of images, and be sure to head over to our original Mid-Ohio post for the video footage of the NSX Prototype on track.

NHTSA, IIHS, and 20 automakers to make auto braking standard by 2022

The National Highway Traffic Safety Administration, the Insurance Institute for Highway Safety and virtually every automaker in the US domestic market have announced a pact to make automatic emergency braking standard by 2022. Here's the full rundown of companies involved: BMW, Fiat Chrysler Automobiles, Ford, General Motors, Honda, Hyundai, Jaguar Land Rover, Kia, Mazda, Mercedes-Benz, Mitsubishi, Nissan, Subaru, Tesla, Toyota, Volkswagen, and Volvo (not to mention the brands that fall under each automaker's respective umbrella). Like we reported yesterday, AEB will be as ubiquitous in the future as traction and stability control are today. But the thing to note here is that this is not a governmental mandate. It's truly an agreement between automakers and the government, a fact that NHTSA claims will lead to widespread adoption three years sooner than a formal rule. That fact in itself should prevent up to 28,000 crashes and 12,000 injuries. The agreement will come into effect in two waves. For the majority of vehicles on the road – those with gross vehicle weights below 8,500 pounds – AEB will need to be standard equipment by September 1, 2022. Vehicles between 8,501 and 10,000 pounds will have an extra three years to offer AEB. "It's an exciting time for vehicle safety. By proactively making emergency braking systems standard equipment on their vehicles, these 20 automakers will help prevent thousands of crashes and save lives," said Secretary of Transportation Anthony Foxx said in an official statement. "It's a win for safety and a win for consumers." Read on for the official press release from NHTSA.

Automakers making the commitment are Audi, BMW, FCA US LLC, Ford, General Motors, Honda, Hyundai, Jaguar Land Rover, Kia, Maserati, Mazda, Mercedes-Benz, Mitsubishi Motors, Nissan, Porsche, Subaru, Tesla Motors Inc., Toyota, Volkswagen and Volvo Car USA.
