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.

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.

Acura NSX hybrid wins Time Attack 2 division at Pikes Peak

Acura sent three NSX supercars up the PIkes Peak Hill Climb and one of them - the TA2 that was a standard NSX with some additional safety equipment - beat out its competition in the Time Attack 2 class by over 11 seconds with a time of 10:28.820. Nick Robinson was the driver. This was not his first time atop the podium, as he won the PP250 motorcycle class last year. The EV concept NSX came in second in the Electric Modified class with a time of 9:06.015. That's good enough for third place overall. Acura says that the TA1 NSX - which had a lighter chassis and a modified racing exhaust – "also campaigned." Both the TA1 and TA2 NSX vehicles used the car's standard three-motor hybrid powertrain.

Acura NSX wins its North American racing debut by more than 11 seconds American-built NSX wins Time Attack 2 class at 100th running of the Broadmoor Pikes Peak International Hill Climb NSX-inspired Acura 4-Motor EV Concept finishes second in the Electric Modified Class The recently-launched 2017 Acura NSX claimed victory today in its North American racing competition debut, climbing the 14,115-foot pinnacle of Pikes Peak and clinching first place in the Time Attack 2 class at the 2016 Broadmoor Pikes Peak International Hill Climb, the 100th anniversary of the running of America's second oldest race. The production-based Acura NSX is powered by Acura's revolutionary three-motor Sport Hybrid Super-Handling All-Wheel Drive™ powertrain (Sport Hybrid SH-AWD®), the first electrified torque vectoring powertrain in the world of exotic sports cars. With added required safety equipment for competition, the NSX negotiated the 12.42-mile course in a time of 10:28.820 to win the Time Attack 2 class of the Broadmoor Pikes Peak International Hill Climb. Nick Robinson, North American R&D team member and engineer in charge of the next-generation supercar's dynamic performance, drove the production-based Acura NSX to victory. Nick is also the reigning PP250 winner from the 2015 Pikes Peak International Hill Climb. "I'm incredibly happy to have won the Production Class with the new NSX!" Robinson reported.
