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.

J.D. Power study sees new car dependability problems increase for first time since 1998

For the first time since 1998, J.D. Power and Associates says its data shows that the average number of problems per 100 cars has increased. The finding is the result of the firm's much-touted annual Vehicle Dependability Study, which charts incidents of problems in new vehicle purchases over three years from 41,000 respondents.
Looking at first-owner cars from the 2011 model year, the study found an average of 133 problems per 100 cars (PP100, for short), up 6 percent from 126 PP100 in last year's study, which covered 2010 model-year vehicles. Disturbingly, the bulk of the increase is being attributed to engine and transmission problems, with a 6 PP100 boost.
Interestingly, JDP notes that "the decline in quality is particularly acute for vehicles with four-cylinder engines, where problem levels increase by nearly 10 PP100." Its findings also noticed that large diesel engines also tended to be more problematic than most five- and six-cylinder engines.

Acura MDX PMC priced at $63,745

The 2020 Acura MDX PMC edition, first unveiled as a prototype at the 2019 New York Auto Show last spring and later shown in production form at the L.A. Auto Show this past fall, is finally arriving in showrooms. And that means we now have actual pricing: $63,745. That includes a hefty $1,995 destination fee, which is $970 more than the charge for a regular MDX and equals that of the NSX supercar. The total represents a $4,470 upcharge over the now-penultimate MDX Advance, at $59,275. What does $4,470 worth of extra specialness buy you? Let us review: Like the previous PMC version of the TLX sedan, the MDX wears trim-exclusive Valencia Red Pearl nano pigment paint, applied with a multi-stage process at the NSX factory. It's set off with gloss-black exterior elements including 20-inch 10-spoke wheels, roof panel, grille and surround, side mirrors, door handles, and antenna, with black-chrome exhaust tips. Inside, the seats are upholstered in black Milano leather with Alcantara inserts and red contrast stitching. Red stitching also appears on the steering wheel, door panels, center console and armrest, and headrests. Floor mats have A Spec logos, and metal shift paddles are also included. Besides the PMC-specific visuals, the model includes a full raft of features, including navigation, heated and ventilated front seats, heated rear seats and steering wheels, adaptive dampers, LED exterior lighting, ELS Studio premium audio, second-row captain's chairs, surround-view camera system, and more.  Beyond the content, what makes the PMC edition unique is that it's partially assembled at the brand's Performance Manufacturing Center (thus, "PMC"), where the NSX is built. Production is limited to 300 units for the U.S. market, with another 30 for Canada. Related video: Acura NSX Factory Tour
