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 teams with Galpin to sport-up the 2015 TLX

Acura used the SEMA Show this week to remind enthusiasts that it still considers itself a performance brand, teaming with Galpin Auto Sports to build a TLX that highlights Acura's sporting and racing heritage.
The TLX is painted a deep shade of blue, called Andaro, and the color will be used on the NSX supercar when it returns to the United States in 2015. It rolls on custom gray wheels with gunmetal and "liquid smoke" pieces, and they're wrapped in Pirelli P Zero rubber. The exterior design is punched up with a body kit that adds side skirts, a rear spoiler and new bumpers to create a more sinister look.
The TLX has a sport suspension kit with coilovers with 36-way adjustable damping. There's also brake upgrades and custom exhaust outlets.

Production Acura NSX spied getting sharper on the 'Ring

Acura hasn't been shy about trotting out the concept version of its upcoming NSX hybrid supercar - we've seen it colorized on Facebook, wearing Super GT drag and running wrapped at Mid Ohio - but until now, we've missed seeing the production version at all. Thankfully, our boys in the field have been diligently camped out by the Nürburgring, just the place for Acura engineers to get the NSX shaken down and ready for the public.
The first thing you'll likely notice (and no doubt appreciate) is that Acura is staying very true to the concept car. The same wind-tunnel-carved wedge shape is in evidence in the car's silhouette, and details like aggressively scalloped engine vents behind the cabin have made it through unscathed.
We do notice that there are some vertical elements at the bottom of the front fascia/grille that appear to be revised, and the mirrors are considerably less slinky than those of the concept car. Still, by and large, we're seeing a direct translation from show stand to real life here.
