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.

2022 Acura RDX pricing starts at $40,345, a $900 increase

Acura showed us the quieter, more featured, and better handling 2022 RDX five-seater crossover in September. With the model expected to drive onto dealer lots in about two weeks, it's time for pricing. The base price for a front-wheel drive RDX goes up by $900 to $40,345 after the $1,045 destination charge. Be warned, that price is only for a Lunar Silver RDX; the four other colors possible on the base trim cost $500, and the three pearlescent hues require both the $2,650 Technology Package and the $3,000 Advance Package. MSRPs for the entire 2022 RDX range are: RDX FWD: $40,345 RDX FWD with Technology Package: $42,995 RDX FWD A-Spec with Technology Package: $45,995 RDX SH-AWD with Advance Package: $50,345 RDX SH-AWD A-Spec with Advance Package: $52,345 RDX SH-AWD PMC Edition: $55,295 As indicated on Acura's pricing sheet, adding SH-AWD to the three front-wheel-drive models requires $2,200. Fyi, the RDX configurator on Acura's web site displays the price for SH-AWD as $2,000, but the summary actually adds the correct $2,200 figure to the tally.   Every RDX next year will be quieter thanks to a retuned Active Sound Control system and, as part of the MDX-inspired redesign, new front fender liners that reduce road noise. The new Technology Package cuts even more cacophony thanks to thicker carpet, acoustic glass in the front doors, more sound insulation throughout the cabin, plus it throws in features like perforated sport seats, 12-speaker ELS audio, parking sensors front and rear, swankier 19-inch wheels, and a rear camera washer. The A-Spec Package takes the rims up to 20 inches, and bundles gear like LED fog lights, heated front seats, a flat-bottom steering wheel, and 16-speaker ELS audio. For 2022, Acura will finally let customers combine the A-Spec with the Advance Package. The latter kit piles on even more sound deadening material, acoustic glass for the rear windows, plus bits like a heated steering wheel and rear seats, a hands-free tailgate, and adaptive dampers. Those dampers are drop wheel size back down to 19 inches, though. The 2022 RDX can be pre-ordered now, examples will be in showrooms come November 2. Related Video:

Acura NSX EV puts winner Tetsuya Yamano back on Pikes Peak

With Pikes Peak right around the corner, Acura is showing off more details about its NSX-inspired all-electric racer. The four-motor EV will be driven in the Electric Modified Class by Tetsuya Yamano, who has been testing the car at the Hill Climb for the past few weeks. Acura is also running two NSX hybrids up the hill in the challenge next weekend. So, what's different inside this NSX-like EV? Like the all-electric Honda CR-Z that Yamano drove up Pikes Peak last year – winning the Challenge Exhibition class with a time of 10:23.829 – the NSX-inspired EV uses two Twin Motor Units (TMU) from the company's Sport Hybrid SH-AWD powertrain. Each axle has a TMU and that means that the car, "has achieved independent torque distribution to all four corners – true four-wheel torque vectoring," according to Acura. That sounds nice, but the real test will be out in Colorado in just a few days.

The Acura EV Concept features a further evolution of the experimental, all-electric, 4-motor Super Handling All-Wheel Drive™ (SH-AWD®) powertrain that won last year's Pikes Peak Challenge Exhibition class. The supercar-inspired Acura EV Concept will be driven by Tetsuya Yamano, who campaigned last year's CR-Z-based electric prototype. The Acura EV Concept is the ultimate embodiment of the all-wheel-drive Electric SH-AWD powertrain featuring a world's first technology that enables four-wheel independent torque allocation. The Acura EV Concept's Electric SH-AWD powertrain produces three times the total system output of last year's electric prototype and is mated to the NSX body. "We've been tuning the car for several weeks at Pikes and have advanced its performance significantly," said Tetsuya Yamano. "We're honored to be running at Pikes in this historical, anniversary year – an event respected by racing fans all over the world." 4-Motor Development Honda R&D has been developing "super handling" technology for more than 20 years in the pursuit of ideal vehicle handling.
