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.

Kia leads J.D. Power's Vehicle Dependability Study for 2022

For the first year ever, Kia leads J.D. Power's annual Vehicle Dependability Study with a score of 145 problems per 100 vehicles. Buick (147) and Hyundai (148) round out the top three. The highest premium brand on the list is Genesis, with a score of 148. It's common for so-called "mass market" brands to lead this particular study, according to J.D. Power, as "premium" brands "typically incorporate more technology in their vehicles, which increases the likelihood for problems to occur" and aren't necessarily built to a higher standard that less-expensive brands. The highest-rated single nameplate is the Porsche 911. It's the third time out of the past four years and the second year in a row that Porsche's quintessential sports car has taken top honors. Porsche as a brand sits in seventh place (162) just behind Lexus (159) and ahead of Dodge (166). At the very bottom of the list is Land Rover with a dismal score of 284; the SUV specialist held the same unfortunate distinction on last year's list. Ram (266), Volvo (256), Alfa Romeo (245) and Acura (244) also performed poorly. The overall industry average score sits at 192 — mass market brands average a score of 190 while premium brands sit 14 points lower at 204. While Tesla is unofficially included in some of J.D. Power's results, the agency says the sample size it has access to for this study is too small to include. As has been the case for the past several years, infotainment systems dominate the list of problems reported by owners. Popular (or unpopular, depending on your point of view) complaints include built-in voice recognition (8.3 PP100), Android Auto/Apple CarPlay connectivity (5.4 PP100), built-in Bluetooth system (4.5 PP100), not enough power plugs/USB ports (4.2 PP100), navigation systems difficult to understand/use (3.7 PP100), touchscreen/display screen (3.6 PP100), and navigation system inaccurate/outdated map (3.6 PP100). While problems with the car's infotainment and technology packages are indeed bothersome, it's important to remember that such issues aren't usually leaving owners stranded with an immovable vehicle like a broken transmission or blown engine would. Culling infotainment complaints from the results would reduce the average problem-per-100-vehicle score by a staggering 51.9 points. The vehicles included in this study are from the 2019 model year. That means owners have had three years to get to know their cars and trucks. It's the 33rd year that J.D.

2013 Buick Verano Turbo vs. 2013 Acura ILX 2.4

Answering The $30,000 Entry-Level Luxury Question
Twenty years ago, a comparison between an entry-level Buick and Acura would have matched a Skylark against an Integra.
Twenty years ago, a comparison between an entry-level Buick and its Acura equivalent would have matched a Skylark against an Integra. The unfair battle would have resulted in the compact American's defeat in nearly every measurable category, as the Japanese competitor was arguably at the height of its powers.
