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 is industry's first supercar with a female design lead

Michelle Christensen. Unless you've been casting about the web for some behind-the-scenes takes on recent exotic car launches or were unusually curious during the early days of the sport crossover trend, her name probably means nothing to you. She grew up in Northern California, where her family drag-raced. Venerables like the 1932 Ford, Plymouth GTX, and Dodge Super Bee rolled through her family garage. And Christensen grew up designing prom dresses for friends and dreaming of working in a pit crew. In fact, she didn't even realize car design was a real profession until junior high, when her father pointed out Chip Foose at a car show. After that, she was hooked, so she went to Art Center College of Design in Pasadena, where she reimagined the Plymouth Barracuda as her senior project. Today, Christensen can add the title of lead exterior designer on the 2016 Acura NSX to her resume. The first woman to lead the shape of a supercar, Christensen actually opened up her "First!" account with Acura in 2005 when the company swooped her up the night of graduation and she became its first female exterior car designer. Her first sketch on the job was a concept for the ZDX, and the bigwigs chose her design for production. She joined the NSX team after the mid-engined concept was introduced at the 2012 Detroit Auto Show, replacing the front-engined V10 concept (we encourage you to go back and look at what was versus what is). Christensen thereafter led a crew of eight through a rework of the sheetmetal, with the focus being to keep the "emotional, 3-D kind of feeling." Reminiscing about her family's utterly unadorned '32 Ford hot rod, she said the NSX team was committed to keeping the design simple and light. Wind tunnel work led to larger bumper, hood and side intakes for better airflow on the production model. That, along with a switch in engine position, gave them a chance to go aggressive and to not only "punch more holes in it and make it more exotic," but also "take it to the gym and beef it up." In line with its decidedly un-retro rebirth, the third brake light that runs across the decklid is about the only nod to its predecessor. At age 34, we're certain we haven't seen the last of Christensen or her designs. Related Video:  

Honda and Acura EVs will officially adopt the Tesla NACS port in 2025

Honda and Acura are the next manufacturers to jump on the NACS bandwagon, and while we heard the first official rumblings in Monterey, today is Honda’s (and AcuraÂ’s) official announcement. The first EV that Honda will launch with the NACS port will be in 2025. Just like every other automaker making the switch, Honda says it reached an agreement with Tesla to adopt the charging port. After that first Honda with the NACS port launches, every new Honda and Acura EV model in North America will have the same port. However, just like many others, Honda and Acura will have EVs on sale prior to 2025 that will ship with the current Combined Charging System (CCS) port. These models will be designed to be compatible with NACS use via a charging adapter, so youÂ’ll ultimately be able to charge them via Tesla Superchargers one day. Outside of this Tesla NACS agreement, Honda says the news today doesnÂ’t change its joint venture with seven other automakers to build an EV charging network and expand the number of charging stations available for all.
