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 Integra to make its racing debut at Pikes Peak Hill Climb

Acura is headed to this year’s Pikes Peak International Hill Climb with a bevy of race cars. Most notable of all is a Pikes Peak-prepped Acura Integra — yes, Acura is already getting the Integra out there for some racing. Beyond the new hatchback making its motorsports debut, Acura is also bringing two TLX Type S race cars and two NSX Type S racers. For the icing on the cake, an NSX Type S will be serving as the official pace car for Pikes Peak this year, too. This particular running of Pikes Peak is special, for itÂ’s the 100th running of the event. The first hill climb at Pikes Peak took place all the way back in 1916; the race went on hiatus during the world wars. As for the cars themselves, Acura provided the greatest detail on the Integra. Modifications include upgraded brakes, new suspension, an HPD differential, wider (and lighter) 18-inch HRE wheels and 245-section-width Pirelli slick tires. The 1.5-liter turbocharged four-cylinder and six-speed manual transmission remain untouched, so itÂ’ll be heading up the hill with the stock 200 horsepower and 192 pound-feet of torque. However, weÂ’ll note the this Integra is sporting some extra-large exhaust tips out the rear, so Acura has clearly done something with the exhaust. The livery for the Integra is an homage to AcuraÂ’s first endeavor into motorsports where the first-gen Integra competed in IMSA and won the 1987 and 1988 championships. Pikes Peak rookie Paul Hubers will pilot the Integra up the hill for Acura. As for the other cars, Acura says that both the NSXs and TLXs are fully prepped for Pikes Peak with plenty of modifications, but doesnÂ’t go into detail about them. The NSX Type S will be trying to beat the previous record set by an NSX in the hybrid fuel class. All of these Acuras, and the rest of the field, will be running up the hill on June 26.

2013 Acura ILX 2.4

Going Mainstream Has Its Privileges
Acura's experiment with niche models has failed. Competing in the luxury car business by filling white space with product just didn't work for the Japanese automaker. In place of slow-selling models like its ZDX and quirky first-gen RDX, the mindset at Acura has recently switched to more conventional products with vastly improved volume potential. The redesigned 2013 RDX, for example, sold almost as many units in 2012 as it did in 2010 and 2011 combined, and the all-new 2013 ILX has sold more units each month - since going on sale in May - than Acura sold in ZDXs and RLs in all of last year.
While the redesigned RDX is a crucial product to compete with luxury compact crossovers, the ILX might be the most important new product for Acura, as a growing number of premium makes are starting to realize the importance of upscale entry-level compact cars. Ironically, this segment was a pivotal part of the brand's success in the 1980s and '90s thanks to the Integra, but Acura completely abandoned the genre when it killed off the RSX coupe in 2006. The addition of the ILX not only gives Acura a competitive small car again, it also drops the brand's entry price by almost $5,000.
