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.

2019 Acura RDX First Drive Review | Boringness banished

WHISTLER, B.C. — Things have come full circle for the Acura RDX. The compact crossover launched in 2007 with an all-new turbocharged four-cylinder engine and an all-wheel-drive system that was sophisticated enough for the brand to affix the Super Handling designation to it. It was a fun, sporty vehicle in a sea of boring competitors, and we liked it enough to write a eulogy of sorts when the second-generation RDX ditched the fun turbo engine in favor of a V6, and dumbed down its optional all-wheel system so much that they dropped the Super Handling name. Acura's mainstreaming of the RDX for its second generation turned out to be a smart play. Sales jumped 94 percent in 2012, the first year that the redesigned RDX went on sale, leapt another 50 percent the following year, and have stayed over the 50,000 mark for the past three years. It may sound surprising, then, that Acura is flipping the playbook back a few pages by swapping its V6 engine back to a turbo four and reinstalling Super Handling All-Wheel Drive. We think it's a smart move. The 2019 RDX is both sportier and more upscale than the model it replaces. It does more than just check boxes. It's interesting, boasts some cool technology, and offers a strong value proposition. The 2019 RDX's all-new 2.0-liter turbocharged four-cylinder engine delivers 272 horsepower and 280 pound-feet of torque. That's down a negligible seven ponies from the old 3.5-liter V6, but up 28 lb-ft, and it's tuned to provide the bulk of that torque in the heart of its powerband — peak torque plateaus between 1,600 and 4,500 rpm. An equally all-new 10-speed automatic transmission sends that power to either the front wheels, or, as was the case with the vehicles we tested, all four wheels. Jumping into a 2019 RDX for the first time, our main powertrain concern was that the 10-speed automatic would generate a ton of unnecessary, and distracting, shifts. This proved to be an unfounded fear. The gearbox does shift quite often under hard acceleration, but does so quickly and without any undue jerkiness. The sheer number of gearing options — the old six-speed auto had a 68 percent narrower spread of ratios — and the torque-rich engine combined to provide excellent straight-line acceleration in any real-world driving scenario we could conjure. The rest of the time we didn't really think about the transmission at all. We did, however, lament the push-button transmission interface.

2019 Acura NSX gets a refresh and an eye-catching new color

After two model years and about 1,000 deliveries to the U.S., Acura's given the 2019 model a few enhancements and a small price bump. The car debuted at The Quail, A Motorsport Gathering, during the festivities surrounding Pebble Beach. While there are no major powertrain changes, some new color options and a few chassis refinements will be appreciated by NSX fans. Let's start with the hardware, since this is a sports car, after all. Most important, there's new all-season rubber, still Continental SportContacts but the next version thereof — the 6. Acura claims better handling in all conditions, and the way tire technology has been improving, we'd believe it. The optional Pirelli Trofeo Rs remain — and remain highly recommended for anyone looking to sample the NSX on track, which is an exhilarating experience. Acura says the rest of the enhancements we'll mention shaved a full two seconds off the car's time at Suzuka, so take that for what it's worth. They consist of a 26 percent stiffer front sway bar and 19 percent stiffer rear bar; 21 percent stiffer rear toe link bushings; a 6 percent stiffer rear hub; and a new software calibration for the computer controlled bits: the SH-AWD system, magnetorheological dampers, electric power steering, and stability control systems. For a car as precisely engineered as the NSX, these are relatively significant improvements. Don't necessarily expect it to shave two seconds off your personal best lap time, but if you're highly attuned to the chassis dynamics, the '19 NSX should offer more precise and direct feedback to the driver. No need to be precisely attuned to the cosmetic changes — they're pretty obvious. Thermal Orange, a new exterior color, and the chrome beak-ectomy (it's not body colored) crown the exterior changes. Inside, the leather/Alcantara combo seats are now available in blue, and the full leather seats can be had in red. While the price for the 2019 model has gone up by $1,500, Acura says that there's now $4,700 in formerly optional equipment (power seats, satnav, premium audio, parking sensors, and sport pedals) included as standard equipment. That sounds like a good deal to us. If you want one, the order books are open and cars will be delivered starting in October. Related Video:
