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 TSX Sport Wagon on the way out?

With Acura widely expected to consolidate its TSX and TL sedans into one model line in the near future, the fate of the TSX Sport Wagon is unsurprisingly in doubt. The long-rumored one-for-two sedan replacement is said to be dubbed TLX, and will sit above the Honda Civic-derived ILX, a model that already encroaches on the TSX's pricing and size. According to Ward's Auto, Acura officials are refusing to confirm that today's TSX wagon - effectively a re-schnozzed European-market Accord estate - is facing extinction. Reading the tea leaves, however, things certainly don't look good - the European Accord itself is said to be on the bubble and may not be replaced.
The TSX Sport Wagon was brought to the US as a niche play for the 2011 model year, with Acura of Canada taking a pass on the bodystyle. Officials said at the time that it hoped to shift 4,000 units per annum, roughly a 10-percent sliver of US TSX sales. And while Acura doesn't normally break out the wagon in its sales reports, Autoblog was able to obtain the model's totals for the last two years: the company sold 3,210 Sport Wagons in 2011, improving to 4,234 units last year. The current 2013 model began trickling into showrooms in December, but some dealers are still looking to clear out remaining 2012 models at handsome discounts.

Honda marks 20 million vehicles made in the USA

Japanese automakers manufacturing in the United States is nothing new. But it was in November of 1982 when the first Honda Accord rolled off the assembly line in Marysville, OH. It was the first Japanese vehicle assembled in the US, and in the nearly 32 years since, Honda has made 10 million Accords here for a total of 20 million cars manufactured in America - enough to span from New York to San Francisco twenty times. It's that double landmark which Honda is now celebrating.
Honda has come a long way in those three decades, keeping that original plant in Marysville on line while expanding to three more - in East Liberty, OH; Lincoln, AL; and Greensburg, IN - with a fifth plant (the Performance Manufacturing Center) opening on the same site in Marysville to build the Acura NSX next year. It also builds engines in Lincoln and in Anna, OH, and automatic transmissions at Russells Point, OH, and Tallapoosa, GA.
Between those seven sites, Honda produces 11 different models, including the Accord, Civic, Crosstour, CR-V, Pilot, Odyssey and Ridgeline as well as the Acura ILX, TL, RDX and MDX. Production keeps on ramping up as Honda produced a record 1.3 million vehicles in the US last year, 95 percent of which are sold in the US.
