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.

2018 Acura RLX refresh packs a new face and NSX DNA

The redesigned 2018 Acura RLX is here, and it's the fastest and most capable sedan the company has ever built. While not all new, there's a host of changes both inside and out, through the two powertrains carry over unchanged. The RLX Sport Hybrid packs a bit of NSX DNA to go along with the new family face. The car will make its full reveal next week at Pebble Beach before it hits showrooms later this year. The first Acura RLX debuted in 2013 as a replacement for the range-topping RL sedan. Sales have been slow, though a slimmed down lineup may help that. Powertrains remain the same, but refreshed styling and the removal of the controversial "beak" grille may help bring in some new blood to Acura dealers. The car comes in two variants, the 310 horsepower RLX with Precision All-Wheel Steer (P-AWS) and the 377 horsepower RLX Sport Hybrid with Super Handling All-Wheel Drive (SH-AWD). That's a lot of acronyms, but there's a lot of tech behind those names. Both models use a 3.5-liter direct-injected V6, though the Sport Hybrid backs that up with three electric motors. It's a similar setup to the Acura MDX Sport Hybrid that we drove in the spring. The RLX P-AWS now sends power to the front wheels through a new 10-speed automatic. Both models get new styling, following on the heels of the updated Acura TLX. The beak is gone, replaced by what Acura dubs the "diamond pentagon" grille. It's handsome and sure to be less divisive than before. In addition to the grille, the RLX gets a new hood, new wheels, and new lighting, with a sea of LEDs lighting up the face. The 2018 model gets three new paint colors to go along with the new bodywork. The RLX Sport Hybrid sits atop the Acura sedan range. As such, standard features include a Krell Audio System, surround view cameras, parking sensors, LED fog lights, remote engine start, ventilated and heated front seats, and heated rear seats and steering wheel. The RLX is available with the AcuraWatch suite of active safety technology. Similar to HondaSense, AcuraWatch comes with automatic emergency braking, lane keeping assist, lane departure warnings, forward collision warnings, adaptive cruise control, and low-speed follow. Unique to AcuraWatch is traffic jam assist. This system works with the adaptive cruise and low speed follow to keep the vehicle moving and following at a set distance in heavy traffic. Look for more photos and pricing later this year.

2019 Acura MDX refresh brings some sharp enhancements

The outgoing Acura MDX has nothing to be ashamed of, but the thing about refreshes is that the engineers and product teams always have something to fine tune. Some of it is planned in advance — the cosmetic upgrades and the A-Spec trim were probably always part of the product roadmap. But there are also some tweaks that seem to be a response to customer feedback. Let's take a closer look. Most important, some of the goodies reserved only for the old Sport Hybrid will now be available on all MDXs. Notably, the Active Damper System — a continuously adjustable valve that controls the flow of hydraulic fluid within the damper — is available on non-hybrid MDXs for the first time. The system has several settings, from plush to firm. We found this system worked very well on the Sport Hybrid during our first drive, so it's a useful upgrade that buyers will be able to readily appreciate. Next up is an A-Spec appearance trim, which looks sportier but doesn't offer any additional performance or comfort features, just like the rest of Acura's A-Spec models at this point. For the MDX, wider 20-inch wheels and a combination of gloss black and "dark chrome" trim compliment a revised front fascia and grille. Inside, the seats get a mix of Alcantara and leather with contrasting stitching, there are unique gauges, sport pedals, and a thicker steering wheel. It looks decent enough, particularly inside, and there's enough there to make the trim stand apart from the more pedestrian trims. Oh, and there's an exclusive color: Apex Blue Pearl. A quick aside on prices: The base MDX without SH-AWD runs an MSRP of $45,295, and the A-Spec (only available with SH-AWD) is $55,795. Normal MDXs get a few more color options, although they'll cost extra: Majestic Black Pearl, Performance Red, and Canyon Bronze Metallic. One no-cost color option that's new is Gunmetal Metallic. Inside, there are some additional interior options, like Desert Olive Ash wood trim, contrasting seat stitching, and standard 4-way power lumbar adjustment on the front seats. Advance Package MDXs get wider 20-inch wheels, too. And now on to those tweaks and enhancements that might not have been planned a long time ago in a product meeting far away. The engine stop/start function has been tweaked to be smoother and quicker, thanks to an upgraded brake sensor and some software tweaks.
