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.

2024 Acura Integra Type S costs $51,995, orders open May 11

The highly anticipated 2024 Acura Integra Type S will start at $51,995 (including $1,195 for destination) and preorders will open up on May 11, 2023, at 10 a.m. Pacific. Now, before you get too excited, know that Acura is only planning to take reservations for "one of the first 200 production units before the high-performance model officially begins arriving at dealerships next month." We'd expect those 200 slots to fill awfully quickly. For those interested in throwing their hats into the virtual ring, the orders will be accepted at Acura.com/Integra. Deliveries to dealerships are planned for June. As we already knew, the Integra Type S will gain a total of 5 horsepower over the mechanically related Honda Civic Type R, though we're not clear on what's changed between the two versions of the 2.0-liter turbocharged four-cylinder powerplant to account for those newly located ponies. A six-speed manual transmission is mandatory, no automatic will be offered. The Type S will benefit from the same dual-axis front suspension design that inhibits torque steer so well in the Type R. Read all the rest of the salient details in our coverage of the Acura Integra Type S reveal. Acura also revealed that the Type S will achieve fuel economy figures of 21 miles per gallon in the city, 28 on the highway and 24 combined. That's down one mpg in the city compared to the Civic Type R, but the rest match up. Now, it is of course worth pointing out that the latest Honda Civic Type R is an excellent car. We not only named it an Editor's Pick, we declared it victorious in a comparison test with its most natural rival, the Toyota GR Corolla (a car that we also like quit a bit). That Honda, which shares a whole host of parts with this new Acura Integra Type S, costs $44,890 (again, including destination). What exactly will account for the $7,105 price difference, and will it be worth it? We will of course have to wait for our turn behind the wheel to find out. But consider our interest piqued.

530,000 Hondas, Acuras under expanded NHTSA investigation for steering problem

Earlier this year, the National Highway Traffic Safety Administration opened an investigation into the 2022 and 2023 Honda Civic. The agency had received 145 complaints from owners stating that the car suddenly exhibited “sticky steering” and increased steering effort. WeÂ’re now learning that the investigation is expanding to include hundreds of thousands more cars. The original probe included around 238,000 Civics, but the NHTSAÂ’s latest report, issued Friday, noted that the investigation is expanding to include more than 530,000 Hondas and Acura vehicles. The 2022 and 2023 Honda Civic, 2023 Honda CR-V, and 2023 Acura Integra are affected. A drastic increase in complaints drove the expansion, as the NHTSA said it had received 1,300 reports and was aware of at least 14 crashes related to the problem. An alarming 11 of those crashes involved a roadway departure due to loss of steering control. Two of them came after the driver allegedly overcorrected, and there are three known injuries from the crashes. NHTSAÂ’s report found that the problem happened primarily in the winter months and after the car had been driven in a straight line for an extended period to warm up the vehicle and gear. Though alarming, itÂ’s worth noting that this investigation has not yet reached the recall stage. Honda acknowledged the problem, noting that it was a manufacturing issue for the steering gear unit. The manufacturing process created conditions that could cause greater internal stress, which can wear and deform the gears inside the steering component. The NHTSA also found that the factory did not guarantee consistent lubrication throughout the gear, which could be the cause of the temporary increase in steering effort. The automaker directed its dealers to replace the electronic power steering gearbox to correct a manufacturing defect, but NHTSA will continue its process, moving to an engineering analysis. If that study finds a defect, it could request a recall. Government/Legal Acura Honda Safety
