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.

Join Autoblog editors for a full video tour of the 2019 Detroit Auto Show

The 2019 North American International Auto Show might have been a little more quiet than past years, but there were still some pretty major reveals, including the Toyota Supra, new Ford Explorer, Shelby GT500, Subaru WRX STI S209 and Kia Telluride. We also saw some lovely concepts like the Nissan IMs and Lexus LC Convertible. Senior Editor Alex Kierstein, Consumer Editor Jeremy Korzeniewski and Senior Green Editor John Beltz Snyder join me, Associate Editor Reese Counts — with Social Media Manager Michael Dylan Ferrara behind the camera — on a long walk through the show. We discuss cars, poke around the stands, dress a bloody wound and answer your questions in the Facebook comments. For more Detroit coverage, you can check out Autoblog's picks for the best in show, listen to our podcast or look at the best images from all the reveals.

2016 Acura MDX gets 9-speed transmission, added refinement

It's a car we barely think about until Acura announces it's done something to it, but the MDX is rather popular with those questing for a crossover. For 2016 the third-generation, luxury three-row people-carrier gets a slightly higher MSRP, but better standard equipment and options to go with it. The big change is that the nine-speed automatic transmission with tighter ratios and faster gear shifts, as well as its push-button gear selector, has finally migrated from the top-dog RL sedan. So too the upgraded twin-clutch Super Handling All-Wheel Drive, paired here with the unchanged 290-horsepower, 3.5-liter six-cylinder. We thought adding three more cogs was supposed to make for better fuel economy, but in some cases the EPA ratings on the 2016 MDX have gone down by one mile per gallon. The base 2015 MDX is rated at 20 city, 28 highway, 23 combined; the 2016 is rated 19 city, 27 highway, 22 combined. Add SH-AWD on the 2015 and you're looking at 18 city, 27 highway, 21 combined; on the 2016 that's 18 city, 26 highway, 21 combined. If you add idle-stop to those models you restore the city and combined ratings, but still lose that extra mile on the highway. On the options list is a group of safety and driver assistance features grouped under the AcuraWatch rubric. You can add the whole kit for $1,500 to the base model, but some of its features like Lane Keep Assist and Forward Collision Warning, which you can also option on the 2015 model, are added with the Technology Package. The full suite, which includes model-firsts like Road Departure Mitigation and Rear Cross Traffic Monitor, is standard once you step up to the Advance Package. Other tech treats get baked into all trims, like the easy entry/exit driver's seat slides back 1.4 inches when you're getting in and out, the TPMS fill assist that sounds a beep when you've inflated the tires to the correct pressure, Siri Eyes Free voice recognition and a frameless rearview mirror. The price to get in on all this is $42,865, a a $1,100 bump over the 2015 model, but that's not a blanket increase across the lineup: the MDX with the Technology Package, for instance, has only gone up $250. The upper limit comes with the MDX SH-AWD with idle stop and the Advance, Entertainment & AcuraWatch Plus Packages for $57,080, a $100 increase over the top-of-the-line 2015 trim. The press release below has plenty of details.
