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 recalling 43k MDX and RLX models over seatbelt issue

If you've ever lived in a wintery climate, you may have noticed something strange: no, not the perilously enticing sparkle of cold metal in the sunlight or the way your warm breath suddenly becomes visible in the frigid air, but the way your seatbelt seems increasingly reluctant to retract as the temperature drops. Acura, however, has found the problem more serious than a minor inconvenience, and is recalling some 43,000 vehicles across the United States to address the issue.
The recall in question affects about 7,000 RLX sedans (from the 2014 model year) and another 36,000 MDX crossovers (covering the 2014 and 2015 model years) to have their front seatbelts replaced. In the affected vehicles and in very low temperatures, Acura has found that "the driver's and front passenger's seatbelts may not release from the retracted position." Needless to say, seatbelts that can't be used don't offer any protection in the event of an accident, so the Japanese automaker is notifying owners and dealers to hook up to have those seatbelts replaced.

Honda updates Takata airbag recall status for some models

The net enveloping vehicles in the Takata airbag inflator recall just seems to keep widening. Honda is now updating its previous campaign to revise the status for even more models that were ever registered in (or originally sold in) 13 high-humidity US states and territories.
All of these vehicles were included in the company's earlier repairs. However, at the time this fix was titled "a safety improvement campaign." This latest action upgrades that condition to "a formal recall," according to Honda's official statement. The models include: the 2003-2005 Honda Accord, 2001-2005 Civic (pictured above), 2002-2005 CR-V, 2003-2004 Element, 2002-2004 Odyssey, 2003-2005 Pilot, 2006 Ridgeline, 2003-2005 Acura MDX and the 2005 Acura RL. All of these need to have their passenger-side, front airbag inflator replaced, and the recall affects Alabama, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina, Texas, Puerto Rico, the US Virgin Islands, Saipan, Guam and American Samoa.
As with the rest of these affected vehicles, it's possible in a collision for the inflator to rupture spraying metal shrapnel at occupants. There are at least 139 injuries attributed to this problem from a variety of automakers so far. Among this latest population of vehicles, Honda says there have been no confirmed injuries or fatalities related to these exploding inflators.
