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.

Lexus gets top brand marks from Consumer Reports; Ford, Jeep hit hard

Consumer Reports has released its 2014 Car Brand Report Cards, with Lexus again reigning at the top and doing so with the same industry-topping score of 79 that it registered in last year's Report Cards. This year, the institute credited its lineup for being "usually quiet, comfortable, and fuel-efficient," noting it's the only brand on the list "to achieve an excellent average overall reliability score." The Car Brand Report Cars list is meant to rank the best all-around vehicles based on CR testing and reliability results tallied by subscribers it surveyed. Each brand included must have sufficient test and reliability data for at least three models, a standard which left out 11 marques including Fiat, Jaguar, Land Rover and Porsche.
This 2014 Brand Report Cars edition is the first of a new format in which sub-brands have been broken out from their parent brands, with Acura using this year to move up the leaderboard into second place with a score of 75 for its "reliable, well-finished and somewhat sporty models." The top three was rounded out by Audi, climbing from eighth to third by scoring a 74 for "well-crafted interiors, nice handling and good gas mileage." Audi scored highest in the road-test portion, its improved reliability aiding its rise. The top nine was completed by Subaru, Toyota, Mazda, Honda, Infiniti and Mercedes-Benz.
Ford and Jeep weighed in at the other end of the rankings, Jeep taking the lowest overall score in the road tests and hampered by "a mix of spotty reliability." Ford was sunk by reliability issues with its MyFord Touch infotainment system which consumers found troublesome enough to negate its cars earning "solid test scores" for being "very nice to drive." Perhaps the rumored switch from Microsoft to Blackberry's QNX for the next generation SYNC will help them out. Cadillac's score also took a hit for infotainment reasons after it was the leading US brand last year, the CUE system in the XTS dragging Cadillac to the bottom of all General Motors brands.

Honda S2000, Acura RSX recalled over brake boosters

Honda has announced a recall that affects two of our favorite, dearly departed cars from the brand's portfolio: the S2000 roadster and Acura RSX coupe. A total of 5,239 S2000 models from the 2006 and 2007 model years are affected by this problem, as are 13,113 2006 Acura RSX models.
"A production error may have allowed brake booster components to be produced outside of the original specifications, potentially causing decreased brake assistance over time, which could increase the risk of a crash," American Honda said in a press release. Thus, dealerships will inspect and, if necessary, replace the brake booster setups in these vehicles, free of charge.
No crashes or injuries have been reported in relation to this brake problem. Honda says the problem was discovered during warranty claim analysis.
