2021 Acura TLX to use dedicated platform and wishbone front suspension

Acura claims the 2021 TLX will be the "quickest, best-handling, and most well-appointed sport sedan in Acura history." The experts at Autoblog won't be able to put that statement to the test for several months, but all signs thus far are positive. After showing off the rear of the car a week ago, Acura just released a new teaser of the front fascia. Along with the photo, Acura announced the upcoming TLX will use its own brand-exclusive sports sedan platform and will have a double wishbone front suspension. Before the 2021 TLX's digital unveiling that will take place, May 28 at 1:00 p.m. EST (10:00 a.m. PDT) on Acura.com, Honda's luxury branch has slowly been releasing enticing tidbits about the all-new four-door. The teasers show the car will look very similar to the beautiful Type S Concept, and a Type S performance variant will use a powerful turbocharged 3.0-liter V6.   The new teaser focuses on the car's handling. In addition to the crude silhouette of the car's front end, the dark image shows that the TLX will ditch the Macpherson struts and use double wishbone control arms for the front suspension. Although the TLX nameplate is not old, as it first debuted for the 2015 model year as a replacement to the TL and TSX, this is a return-to-roots type of move. Acura has had success with the wishbone suspension in past performance cars that gave the brand name its weight such as the 1986-1995 Legend, 1990-2001 Integra, 1996-2014 TL and TL Type S, and 1991-2005 NSX. The current NSX hybrid supercar also uses the same setup, which Acura says has "more precise control of wheel camber, caster, and toe angles," and increases tire contact patches. The TLX is also expected to have a "highly rigid body" and a "performance-focused chassis."  For now, that's all that is known about the upcoming TLX, but enthusiasts won't have to wait long to learn more. Full info will arrive May 28. Related Video:

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.

Singer Porsche, Koenigsegg, NSX: Leno's life doesn't suck

Jay Leno had quite a productive trip this year during Monterey Car Week. Not only did he get to pal around with Ian Callum and check out the Pebble Beach Concours d'Elegance, but the denim-clad comedian also headed to The Quail to talk to some prominent figures in the modern sports car scene. Capping off the fun, he got to take a drive in a Mercedes-AMG GT S, too Perhaps the highlight of this show is a nearly 10-minute interview with Christian von Koenigsegg. The founder of the Swedish hypercar company digs deep into the Agera One:1's engineering details, relating interesting facts about the aerodynamics and transmission. In addition, Leno chats with Rob Dickenson of Singer about its newly reimagined Porsche 911 Targa, and he gets the latest scoop on the Acura NSX's progress from newly promoted Acura Vice President and General Manager Jon Ikeda. If you like hearing about the nuts and bolts of sports car development, then this video can't be missed. Of course, we were there at Monterey, too, and we pointed our own cameras at some of the amazing machinery, both vintage and modern, at all the various car-focused events of the week. Take a look back at some of our own cool footage in the videos below. Related Video:
