New 2022 Acura MDX platform to underpin future Hondas

The 2022 Acura MDX introduces a new platform to the Acura and Honda lineup called the Global Light Truck Platform, and it's currently exclusive to the MDX. The new 2021 Acura TLX is also built on a totally new platform that isn’t shared with any other Honda or Acura. Going further back, when the redesigned 2019 RDX debuted, Acura said that model was built on “a new-from-the-ground-up, Acura-exclusive platform." ThatÂ’s three totally-new and Acura-exclusive platforms in a short time period, and it got us thinking. What is Acura up to here?  Most manufacturers these days are increasingly going in the exact opposite direction. VolkswagenÂ’s MQB architecture underpins everything from the hot hatch GTI to the gigantic Atlas. ToyotaÂ’s TNGA platform has multiple sizes/versions, but Toyota still considers them related and will tell you that TNGA is the basis of cars from the Corolla on up to the Highlander, plus the Lexus UX and ES. You can find similar stories all across the industry, in both luxury and non-luxury brands. Acura, on the other hand, appears to be taking a totally different approach. To get some clarity on strategy, we reached out to Acura. The answers are multifaceted, but Acura says it's spending money where it pays dividends for performance — but there's also more sharing between models than it might look like on the surface. “The definition of what constitutes a 'common platform' varies by automaker,” Acura exclusively told Autoblog during a wide-ranging e-mail interview involving the input of numerous engineers and product planners. “For us, the most fundamental value is to maintain the same carry points throughout production and enable us to produce different vehicles in the same manufacturing environment.” As an example, the TLX and RDX feature similar carry points in the chassis to enable their production on the same line, but thatÂ’s where the two diverge. “The TLX is different in that it has a bespoke platform that is not shared with any other Acura or Honda vehicle,” Acura says.

Acura's MDX SEMA concept took the wrong parts from the NSX GT3

When it comes to SEMA show cars, the more absurd the better, such as with the 1,040-horsepower Bisimoto Hyundai Santa Fe. That's not the case with Acura's custom MDX. This crossover was designed to match the NSX GT3 racecar, and gets a custom trailer to tow it. However, instead of doing something awesome like dropping in the NSX's twin-turbo V6, Acura decided the defining characteristics of the race car were the paint, splitter, and wing. So that's what the MDX and trailer got. In addition to a matching white paint scheme with orange and black accents, the SUV wears a massive front splitter that looks like a shelf stuck close to the ground. It's the only aero modification on the vehicle, and it just looks silly, what with the massive gap between the base of the bumper and the splitter itself. There aren't any performance modifications on this SUV either, except the lowered suspension, so the only thing the splitter is likely to do is break off on the first mildly steep driveway it comes across. To complement the MDX's dubious aero aid, the custom trailer gets a "wing" at the back. Actually, it looks like Acura slapped some endplates on the back to give it a wing look. The trailer also gets running boards that extend the splitter along the side. Maybe it all works together to keep the trailering rig planted. But probably not. If Acura wants suggestions for next time, we suggest a mid-engined MDX, or perhaps one with a wild hybrid system. We'll call this a missed opportunity.

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.
