Acura product roadmap leak points to 'compact Type S' and MDX Type S

The Type S moniker is back along with the 2021 Acura TLX Type S sedan. And today, the internet has sprouted some more Acura Type S news. We caught wind of a forum post on Acurazine through a thread on Reddit that includes a link to a video allegedly shown during Acura’s 2020 dealer meeting webcast. That video doesnÂ’t appear to be live anymore, but an enterprising individual happened to screenshot the most important slide from the video: AcuraÂ’s product roadmap to 2022. HereÂ’s the link youÂ’re looking for. Take this information with a grain of salt. ThereÂ’s a good chance that this intel is correct, but plans change. Most imminent is a redesigned Acura MDX with a Type S variant. We expect an MDX Type S to follow the same formula as the TLX Type S. AcuraÂ’s new 3.0-liter turbocharged V6 would be a fine candidate for this duty. With that powerplant (horsepower unknown, but likely around 400 ponies), it could punch up against SUVs like the Mercedes-AMG GLE 53, or punch down to the Ford Explorer ST. tuned suspension, plenty of appearance add-ons and sportier interior would also likely be along for the ride. ItÂ’s placed directly after the TLX on the chart timewise, so thereÂ’s a good chance that we see a new MDX soon. Next up is the one that weÂ’re especially excited about. A new Type S “compact sedan” is on the way. Acura neglected to give this one a name, which is odd, unless thereÂ’s a big secret it wants to keep. Right now, AcuraÂ’s small sedan is called the ILX. In past (and better) years, Acura named its small cars Integra and RSX. Might we see the return of the Integra name? Or perhaps RSX? ThereÂ’s precedent for an RSX Type S, and this small Acura appears to be getting the Type S treatment.  So, what might a small Acura Type S look like? The car could borrow hardware from the Civic Si, or it could borrow from the Civic Type R. A more luxurious Civic Type R with AcuraÂ’s delightful and sharp styling would be splendid. ItÂ’d be dialed back to fit the Type S name, but nearly anything would be better than the ILX wallowing at the bottom of AcuraÂ’s lineup today. WeÂ’re left to guess at the details for now, but the roadmap shows that car arriving by 2022. There are two other small nuggets of info weÂ’ll point out on this roadmap. Acura doesnÂ’t list an RDX Type S anywhere on it. That could be because the RDX was recently redesigned, so itÂ’s not one of the completely new vehicles listed in the step ladder of new product.

Acura recalls 7,387 new RLX sedans over suspension bolts

Acura has announced a recall for the 2014 RLX due to improperly tightened rear suspension bolts that could come loose and increase the risk of a crash. The National Highway Traffic Safety Administration has yet to formally issue a recall notice for the RLX, but Acura says that a total of 7,387 RLX sedans are affected, which seems to include markets outside of the US as there have only been 4,456 of the sedans sold through November.
While there isn't an official NHTSA statement, there is one complaint on the government agency's site for a similar incident that caused a driver to almost lose control of the vehicle. Recall notices will be mailed out to customers starting next month, but in the meantime, Acura has issued a press release, which is posted below, and includes contact information that will be useful for affected RLX owners.

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.
