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 2019 RDX Prototype | New era for a popular crossover

Acura took the wraps off its sleek new RDX Prototype today at the Detroit Auto Show, displaying a completely redesigned, re-engineered crossover that heralds a new era for design and technology for the automaker. Acura says it's a pretty close representation of the production version due out midyear as a 2019 model, save for the highly stylized side mirrors and wheels. The Prototype serves as the third generation of the RDX, and Acura says it's the first full embodiment of the new exterior and interior design language first introduced on the Precision Concept, shown in Detroit in 2016, and the Precision Cockpit, a concept interior it unveiled in Los Angeles in 2016. So in addition to the Precision's diamond pentagon grille, which has already made it to the TLX, the crossover adopts the Precision sedan's low, wide stance and sculpted body panels. Compared to the outgoing RDX, the new version adds 1.2 inches of width and 2.5 inches to the wheelbase, with a shortened front overhang and wheels pushed to the corners. Headlamps and exterior lights are all LED. The RDX Prototype debuts the all-new Acura True Touchpad interface, which combines a touchscreen and remote interface in one Android-based operating system. There's a 10.2-inch full-HD display atop the center console that's operated via a remote tracking pad mapped to the center display, plus an interactive heads-up display. (Here's a good video explainer for how it works.) It also has a new and improved natural-language voice-recognition system. View 12 Photos Inside, there's more space, rear legroom and cargo space. A floating center console is inspired by the Precision Cockpit, plus high-grade materials including nappa leather, brushed aluminum and Olive Ash wood. It'll also be the first Acura SUV offered with the brand's sporty A-Spec trim, which will eventually be part of all core Acura models developed moving forward. And all RDX models will come equipped with a new ultra-wide panoramic sliding moonroof, the largest in its class. Acura is building the new RDX on an Acura-only platform that gives it a lighter and stiffened body, new chassis and all-new powertrain that it says will be its quickest and best-handling RDX to date.

Acura reveals Ludacris' restored Legend, Galpin ILX at SEMA

Acura gave us a hint couple of weeks ago at what it had in store for the SEMA show this year. The Japanese luxury marque has detailed the full extent of its presence at this year's tuner expo, but the main act under the Acura tent (oddly enough) isn't a new vehicle. The star of the show is a 1993 luxury sedan with celebrity provenance. The Legend belongs to rapper-turned-actor Chris "Ludacris" Bridges, of hip-hop and Fast & Furious fame. The automaker has thoroughly restored and modernized the vehicle that featured on the cover of his ninth studio album Ludaversal. At the end of a two-month project, the sedan has been refinished in a custom shade of Warm Cashmere with Ice Pearl. It now rides on 18-inch Rays alloys with Bridgestone Potenza rubber, fitted to a suspension lowered by two inches with H&R springs and Eibach camber kit. It has upgraded brakes with six-piston calipers up front and four-pots at back, and a Pioneer audio system with Alpine subwoofers and Apple CarPlay integration. To complement the Legend, Galpin worked up a 2016 Acura ILX. It has an aero kit, fog lights, custom exhaust, coilover suspension, Borla exhaust, and 19-inch wheels with Pirelli P Zero rubber. The body's been repainted in Sunburst Yellow with gray accents, and sports an interior with perforated leather and gold trim. There'll be another ILX on display with Acura Genuine Accessory parts as well. But the Japanese automaker won't miss the chance to display its new NSX. The supercar's being showcased in a new shade called Nouvelle Blue Pearl. Watch this space for live photos from the show floor, and scope out the details in the press release below in the meantime.
