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 MDX Type S specs boast 355-hp turbo V6, air suspension

Details have finally emerged about the new 2022 Acura MDX Type S. Positioned as the performance-oriented member of the MDX range, the midsize luxury SUV gains a turbocharged V6, Brembo brakes, an air suspension, and a longer list of standard features. Acura takes the heritage-laced "Type S" designation seriously; the badge also appears on the NSX and on the TLX. While we love the thought of an NSX-powered MDX, it's the TLX that was asked to provide its engine. Power comes from a new 3.0-liter V6 that's turbocharged to 355 horsepower and 354 pound-feet of torque. Acura points out these figures make the MDX Type S the most powerful crossover or SUV it has ever released. The six-cylinder spins all four wheels via a 10-speed automatic transmission that has been redesigned to provide quicker shifts, and a Super Handling All-Wheel-Drive (SH-AWD) system programmed to send up to 70% of the engine's torque to the rear wheels. And, as always for Acura's SH-AWD, 100% of that torque can be sent to the left or the right wheel (aka torque vectoring). Acura's first air suspension system appears on the MDX Type S. Adaptive and adjustable, the setup relies on data sent by an armada of sensors and on user input to make the ride sporty, comfortable, or anything in between. Using air springs also allowed Acura to give the Type S a lift mode, which increases the ground clearance by about 2 inches when users need to drive in deep snow or on rough terrain. Next, engineers turned their attention to the brakes. Brembo provided four-piston front calipers designed to work with rotors that are about half an inch bigger than the standard MDX's, and Acura points out that it tuned the electric-servo system to give the Type S a pedal stroke that's similar to the NSX's. The red calipers fitted to both axles are visible through 21-inch wheels wrapped by Continental ContiSeal self-sealing tires. Painting the calipers red was purely an aesthetic decision, but many of the other design changes that help the Type S stand out from the regular MDX serve a purpose. For example, the engine bay receives about 10% more air thanks to a redesigned grille. And, the vents on either side of the front bumper direct cooling air to a pair of sub-radiators mounted on either side of the engine bay. Some of these functional changes aren't immediately visible: Acura went as far as relocating the battery to the trunk to improve weight distribution.

Honda sending two NSX racers and new EV concept to Pikes Peak

Honda is always good for a few interesting Pikes Peak entries. In 2015, Acura supplied a 2017 NSX prototype for pace-car duty. This time around, two NSXes will compete alongside a reconfigured version of the company's four-motor electric racecar. Those aren't the 2016 entries above. The one on the right is last year's pace car and the one on the left is a first-gen NSX that did the hillclimb the past few years. The 2016 cars haven't been unveiled yet, but we know that one will be in the Time Attack 2 Production class, which is mostly stock with the addition of items like a roll cage, and the other will be in Time Attack 1. TA 1 allows modifications to the powertrain, additional aero aids, suspension changes, and other tweaks, so expect to see a lot more power and a big wing on the back. The cars will be driven by James and Nick Robinson, brothers who work for Honda R&D in Ohio. Honda will use a version of the four-motor electric powertrain from its 2015 CR-Z Exhibition class entry in a new EV. (We got to drive a non-race tune of this setup in Japan last year.) The 2016 version, which will wear a different body, moves to the Electric - Electric Modified class of last year's frontrunners. We're told this car is aiming for an overall win at the 2016 race; the CR-Z took 11th place overall in 2015. The EV will again be driven by Tetsuya Yamano, a Japanese Super GT driver. Oh, and there will of course be a factory entry or two from Honda's Powersports division. Honda engineer Keith Steidl will ride a 2015 TRX1000 ATV in the Pikes Peak Challenge - Exhibition Powersport class. In the past, Honda has fielded plenty of other neat stuff in the Race to the Clouds. In 2012, it ran an NSX fitted with a twin-turbo V6 from an LMP2 car, and the 2013 race saw the very practical 532-horsepower turbocharged Odyssey minivan join the Exhibition class. The 2016 race marks the Pikes Peak hillclimb's 100th anniversary (but not the 101st running since competition took some breaks back in wartime). We're looking forward to June already.
