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.

Honda expands Takata airbag recall to 5.4M units in the US

While Honda already announced plans to take its front driver's side Takata airbag inflator recall nationwide, the automaker has now officially reported on the number of affected vehicles and the specific models in need of repair. The expanded campaign covers an estimated 5.4 million units across the US, including those already being fixed under the previous regional actions. That number is an expansion of the five million units initially reported by NHTSA. The affected models under the nationwide recall are the 2001-2007 Accord with a four-cylinder engine, 2001-2002 Accord V6, 2001-2005 Civic, 2002-2006 CR-V, 2003-2011 Element, 2002-2004 Odyssey, 2003-2007 Pilot, 2006 Ridegline, 2003-2006 Acura MDX, 2002-2003 TL and 2002 CL. For customers who expressed concern about their vehicle's safety, Honda had already been replacing the inflators nationwide. It's possible for the inflators in these vehicles to rupture when inflating the airbag, spraying metal fragments at occupants. This problem has been blamed for at least five deaths worldwide and at least 139 reported injuries. In its statement, Honda said that it worked with Takata to test the recalled inflators in the original high-humidity recall regions, and there were no abnormal deployments in these evaluations. Honda will begin notifying owners by "over time," according to its statement. Priority will be put on the geographic areas with the highest risk of ruptures. Those in the original recall region were contacted in September. Earlier in December, Honda partnered with Autoliv to supply the automaker with replacement inflators for this campaign. Autoliv predicted it would take six months for deliveries to start. Takata also increased its production of substitute components. Scroll down to read the company's announcement of this nationwide expansion. Statement by American Honda Regarding National Safety Improvement Campaign: Driver's Front Airbag Inflator Supplied by Takata Dec 8, 2014 - TORRANCE, Calif. Honda will voluntarily expand a regional Safety Improvement Campaign initiated in June 2014 (NHTSA No. 14V-351) into a national Safety Improvement Campaign affecting certain 2001 through 2011 Honda and Acura vehicles in the United States to replace the driver frontal airbag inflator, free of charge. Honda is expanding this Safety Improvement Campaign to address concerns raised by its customers whose vehicles were not included in the regional campaign.

Acura TL gets its top chopped

The roofless Acura TL you see above is a product of Newport Convertible Engineering. No stranger to taking the lids off of Acuras - and a bunch of other cars, like this Jaguar XJ and this Toyota FJ Cruiser - NCE says it was the first US coachbuilder to produce an Acura NSX convertible.
NCE says the conversion takes about six weeks to complete, comes with a five-year warranty from the supplier and doesn't void the original warranty from Acura. On top of that, the interior fitments like sun visors, trunk space and rear seat belts all remain unaltered. Customers who are absolutely against the B-pillar can have it removed, but NCE says "The vehicle will be designed differently without the center bar."
To our eyes the TL looks pretty all right without a roof, and with stripes. NCE will shortly be preparing convertible versions of the 2013 Range Rover Supercharged Autobiography, Porsche Cayenne and Cadillac XTS. For Acura owners, there's a press release below with information on NCE if you have a TL and an urge to go way beyond the sunroof.
