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.

Acura RLX gets chassis upgrades, AcuraWatch for 2016

As Acura's flagship sedan, it makes sense for the RLX be available with the brand's premiere technology. So for the 2016 model year, two trims of the luxury vehicle are getting the latest version of the AcuraWatch suite of safety tech. While the 310-horsepower, 3.5-liter V6 carries over, all trims of the 2016 RLX get an updated suspension tune with decreased spring rates and a less stiff rear stabilizer bar. The changes should provide a more plush, quieter ride inside. There's also a new color available called Acura Silver Metallic. When equipped with either Technology Package or the Advance Package, the 2016 RLX also gets a mix of cameras and radar to provide several safety luxuries that the brand wraps together as AcuraWatch. The system includes things like adaptive cruise control, collision mitigating braking and blind spot information. This improved version adds a Cross Traffic Monitor and Road Departure Mitigation. The latter aid watches the lines on the road to help keep the sedan in its lane. If RDM detects a possible accident, it can even provide steering and braking assistance. Furthermore, the Advance Package now receives Acura's Surround View Camera that places four cameras on the sedan to provide a 360-degree view when needed. The RLX's pricing remains the same from last year with the base version starting at $50,590, plus a $920 destination charge on all models. The Technology Package takes the price up to $54,450, and models with the Advance Package will run $60,450. 2016 Acura RLX Adds AcuraWatch™ and Other Enhancements to Elevate Premium Sophistication and Value AcuraWatch™ expands scope and content of safety and driver assistive technologies Chassis tuning enhances ride quality; 19-inch wheels with new bright finish standard on all trims Manufacturer's Suggested Retail Price (MSRP) unchanged With the most comprehensive suite of safety and driver assistive technologies yet available on an Acura, the 2016 RLX luxury sedan goes on sale March 3 with manufacturer's suggested retail prices (MSRP) unchanged from the previous model year. This price hold represents a significant value, especially for the Technology package due to the addition of AcuraWatch™ and Advance package that includes the first U.S. application of Acura's Surround View Camera system3. Both RLX packages will also adopt the application of Road Departure Mitigation (RDM) and Cross Traffic Monitor.

Honda's latest fuel pump recall covers 761,000 vehicles worldwide

Honda will recall around 761,000 vehicles worldwide to replace fuel pumps that could fail and lead to stalling engines. This recall, which is described in the National Highway Safety Administration campaign number 21V215000, isn't the Japanese automaker's first recall for bad fuel pumps. It includes 628,000 vehicles sold in the United States. Honda isn't aware of any crashes or injuries related to the issue. This most recent recall includes models from both Acura and Honda, some from 2019 only and others stretching into the 2020 model year. From Acura, some ILX, MDX, MDX Sport Hybrid, RDX and TLX models are included. From Honda, the recall covers certain Accord (including the Hybrid), Civic (Coupe, Sedan and Hatchback and including the Si and Type R), Fit, HR-V, Odyssey, Passport, Pilot and Ridgeline. Finally, some Honda CR-V models from 2018 and 2019 are also included. Less than a year ago, Honda issued a recall over the fuel pumps of 136,057 vehicles in the U.S., some of which seem to overlap with this latest recall. Back in 2019, two separate recalls covered well over half a million vehicles for other fuel pump-related maladies, though it's not clear if any or all of these issues are related. With so many recalls over fuel pumps, it would be a good idea for owners of 2018-2020 Honda vehicles to enter their VIN numbers at either Honda's dedicated recall website or use the various tools provided by NHTSA.
