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.

2021 Acura TLX nabs Top Safety Pick+ honor from the IIHS

The Acura TLX is all-new for 2021. It's built on a new architecture that we're told is the brand's most rigid other than the NSX. In our first-drive review, we called it "a true enthusiast's sedan." Now, we know that another benefit of the car's redo is improved crash performance, as the new TLX has earned a Top Safety Pick+ award from the Insurance Institute for Highway Safety. The 2021 TLX bettered its predecessor in the challenging driver's-side small-overlap front crash test, achieving a Good score versus the previous model's Acceptable rating. The 2021 TLX also garnered a Good score for the passenger-side small-overlap front crash test (the previous version was not tested) and for the agency's other crash tests as well: moderate-overlap front, side-impact, roof crush and head restraints and seats. Additionally, whereas the previous TLX's headlights were deemed Poor, the new TLX's LED headlights were judged Good and are standard on all trim levels. Also, the TLX's collision-avoidance technology earned Superior ratings in both the vehicle-to-vehicle and the vehicle-to-pedestrian test evaluations. Related Video:

Acura gives us a lightning-quick glimpse of the NSX Type S

Acura released a short preview film to give fans a fast-paced look at the limited-edition NSX Type S. Scheduled to break cover tomorrow, August 12, it's being boldly presented as the final evolution of the second-generation model. The eight-second flick posted on various social media channels provides us with a peek at the Type S' front end. It shows two cars speeding towards the camera down what looks like a race track's main straight. Acura wants to keep the Type S under wraps until its big debut, so the footage gets blurry as the cars speed by; that's why it's called a teaser. We nonetheless think we can squint and discern a redesigned front end with larger air intakes.  Acura might have chiseled bigger vents into the front bumper because the Type S needs additional cooling air. It's powered by a mid-mounted engine, but there are radiators located right behind the front bumper in the regular-production model. Of course, we're not discounting the possibility that the vents were merely added for show. As we previously reported, the visual changes will also include a red engine cover and black exterior accents. Additionally, the Type S will offer more power than the standard, 573-horsepower NSX and sharper handling. Acura will build 350 units of the NSX Type S, and 300 of those have been earmarked for the American market. The model will make its public debut on August 12 on the sidelines of Monterey Car Week, so we won't have to wait long to learn about the improvements the company has made. If you want one, act fast; if you want the first one, bid high. Serial number one will be sold to the highest bidder at Mecum's Monterey sale on August 14, 2021. The proceeds from the sale will benefit a number of charities. As for what's next, nothing suggest there's a third-generation NSX on the way, but the GT3-spec race car will soon receive a round of updates and it might continue racing until 2024. Related video:
