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 NSX GT3 non-hybrid racecar on sale soon

Just over a year ago, Acura debuted the NSX GT3, the FIA GT3-spec racecar based on the automaker's latest and greatest. While it took years for the road car to hit the streets, the NSX GT3 was developed in a relatively short amount of time. This year, the car competed in several races under the factory banner, racking up 50,000 miles and two race victories. Today, Honda and Acura announced the NSX GT3 will go on sale for private teams. Think of the NSX GT3 as a stripped out version of the standard NSX sans hybrid system. The 3.5-liter twin-turbo remains, but, since there are no electric motors up front, all the power is sent to the rear wheels through a XTRAC semi-automatic 6-speed sequential transmission. The chassis is built in Ohio right alongside the regular NSX. The same goes for the engines. The block, heads, valve train, crankshaft, pistons, and dry-sump lubrication system are the same specification as the production car. Final assembly is completed in Italy. This past year, the NSX GT3 competed under the Acura banner in the WeatherTech SportsCar Championship GTD class and the Pirelli World Challenge GT category. In addition to those series, the car is built to compete in the Blancpain GT Series and 24 Hours Nurburgring in Europe, the Super GT GT300 class in Japan, as well as other GT3-spec race series. Different divisions of Honda will be handling global sales, with HPD responsible for the North American market. US pricing hasn't been announced, but converting the European models start at about $545,000. Now we just want to see a lightened, non-hybrid version of the NSX on the street.

Honda finds new Green Path to reduce CO2 emissions

In the wake of the Volkswagen diesel scandal, it's impossible to hear an automaker talk about its overall environmental efforts and not think to yourself, "for real?" Still, we're willing to listen. And Honda representatives gave it their best shot yesterday in Marysville, OH as they introduced a small group of journalist to the company's expanded initiative aimed at cutting CO2 emissions and the total life-cycle environmental impact of Honda products. Called Green Path, the initiative now includes a $210-million expansion at Honda's Marysville, OH manufacturing plant to install a better, cleaner paint shop. Speaking at the facility yesterday, Honda representatives said that the plant room is not only better for the environment (it uses limestone dust instead of water to capture paint particles, for example, reducing water usage by about 2 million gallons annually. Overall, the new paint shop will have 60 percent less VOC emissions and reduce CO2 emissions by 18 percent), it also makes the cars look better. That's whey the two-step temperature curing process will initially only be used on Acuras to differentiate them from the competition. Honda will fire up trials in late 2017. There's more to Green Path than the new paint show, of course. The company wants to reduce - in some cases eliminate - what it calls substances of concern (SOCs), things like lead and mercury. There are also new wind turbines in Ohio to supply power to Honda plants, the Environmental Leadership Program for independent dealerships to make their own green moves, and swapping out fluorescent light bulbs for LEDs, among other efforts. In the Marysville Auto Plant, for example, the Assembly department has over 10,000 task light bulbs. The fluorescent ones used to need to be replaced every three years, but the new LEDs have a life span of 16 years. Honda says that calculating up the impact of all of these little changes will remove an average of 3.822 kilograms of CO2 from the production tally of each car it makes. The company's stated goal is to reduce its total greenhouse gas emissions by 50 percent (compared to 2000 levels) by 2050. You can find out more in Honda's press release and video, below.
