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.

The all-women Acura NSX team previews a way forward for racing

DAYTONA, Fla. — There is a team at the 24 Hours of Daytona that's just like any other team, with experienced drivers who rightly earned their spot in the top endurance racing series in America. They are prepared to run a full season in a competitive car, and they even set the fastest time in their class at the pre-season Roar Before the 24 test. The only difference between this team and any other is that its drivers happen to be women. We went to Daytona to talk to them about their journey to the race. The No. 57 Heinricher Racing with Meyer Shank Racing Acura NSX GT3 Evo team features a roster of talented, experienced drivers: Katherine Legge, Simona de Silvestro, Bia Figueiredo and Christina Nielsen. While there have been four other all-women lineups at Daytona before, the No. 57 team is the first to be considered truly competitive. Team founder Jackie Heinricher, a biotech CEO who has raced in Ferrari Challenge, Global Rallycross Lites and Lamborghini Super Trofeo, was coached by Legge. Two years ago, she had the idea to run a car full of women – and not just a token effort, but rather a car full of drivers who could win. "The car does not know your gender, and I feel as if this sort of professional effort legitimizes that in a way that's particularly important and inspirational outside of racing," Heinricher told Autoblog. Heinricher had seen Legge struggle to get the right funding for rides before, so she didn't want to limit this team to whoever could pay. So, she first lined up the funding, thanks largely to support from primary sponsor Caterpillar. It took awhile, though, as many companies simply told her that they were out of racing sponsorships entirely. "I think perseverance might be the most underrated human quality," Heinricher said. "I just didn't give up." After funding was in place, she found a competitive partner in the Meyer Shank Racing crew, whose owner Michael Shank has run a pair of factory-backed Acura NSX GT3s in IMSA's GTD class since 2017. The GT3 shares an engine and turbo with the road-going NSX but ditches the hybrid system, making it about 670 pounds lighter. The No. 57 car is an EVO variant, which Legge helped develop, and it features improved aerodynamics to better suit it to the mix of pro and amateur drivers who take shifts racing in the GTD class. Legge had been on Shank's NSX team for the past two years as well, so Heinricher reached out to her for help assembling women who truly had the ability to win.

BMW reclaims US luxury sales crown from Mercedes

The numbers, they are in: BMW has reclaimed the luxury-sales crown from Mercedes by a margin of 9,347 cars. Mercedes donned the king's headgear in 2013 after a strong final quarter of 2013 when the new CLA and S-Class poured out of dealerships. This year, led by the 3 Series/4 Series and X5, BMW sold 339,738 units – a 9.8-percent increase year-on-year. Mercedes, led by the C-Class and M-Class, saw its sales go up by 5.7 percent to 330,391 units. We'll have to wait a bit to see if there's another registrations-vs-sales challenge as in 2012, when BMW was anointed US luxury ruler. Behind them, a dark horse named Lexus nudged closer to the leading Teutons, selling 311,389 cars. The Japanese luxury automaker also had the biggest gain among the top three, its sales rising by 13.7 percent compared to 2013. Audi had the biggest sales of anyone among the top five, though, with a 15.2-percent gain to 182,011, which moved it a spot ahead of Cadillac; the Wreath-and-Crest brand dropped 6.5 percent to 170,750. Acura (167,843), Infiniti (117,300), and Lincoln (94,474) took the final positions. Speaking of Lincoln, sales at the once-mighty luxury marque stand as the mightiest jump of any on this list, up 15.6 percent. That's the power of Matthew McConaughey... and better cars and a new crossover, sure. So now that we're back to Round One of 2015, in case no one else has said it yet: "Ok, fight!"
