2019 Acura RDX crossover gets turbocharged power, A-Spec version

NEW YORK — Calling the RDX that Acura showed at this year's Detroit Auto Show a "concept" was stretching that term to the limits of credulity. The production version of the 2019 RDX is here, and this turbocharged crossover with available AWD looks darn near identical. While it offers all-wheel drive like its Lexus NX and Audi Q3 competitors, Acura's next-generation SH-AWD should be a serious selling point. Let's cover that "Super Handling All-Wheel Drive" system for a moment. It takes power from the 2.0-liter, 272 horsepower and 280 pound-feet of torque engine and routes it up to 70 percent rearward, and there's real torque vectoring (rather than brake-based faux vectoring) to shift 100 percent of that rear axle power to either wheel. The broad strokes are similar to the outgoing model's system, but there's much more available rear power bias — in the 2016 model, up to 40 percent could be sent to the rear. And that was up from 25 percent for pre-2016 models. The takeaway is that the RDX should handle a lot better on both dry and slippery pavement, and feel a bit sportier doing it. A new engine may help as well. The outgoing 3.5-liter V6 is replaced by a turbocharged four-cylinder, almost certainly related to the unit in the Accord and Civic Type R, and tuned somewhere in between those cars (252 and 306 horsepower, respectively). We expect the new engine to be lighter than the old V6, and less weight off the front end should improve steering feel and handling. For those keeping track, the new engine is down 7 horsepower but up 28 pound-feet in torque, and thanks to turbocharging the torque band starts down low and is relatively flat, so more oomph from a stop and on through the rev range. The six-speed automatic is gone, replaced by a 10-speed automatic. Most of its competitors use six- or eight-speed units, so that'll be a marketing focus. As you'd expect, the individual ratios are closer-spaced but the total ratio spread is, according to Acura, 62 percent wider than the outgoing automatic. There are steering-wheel-mounted paddles if you'd like to shift yourself. Since the styling is very much a lightly retouched Prototype RDX from the Detroit show, it's nice to be able to give a sense of the new car's proportions with hard numbers. First of all, it's riding on a 2.6-inch longer wheelbase. Overall length is 187 inches, up from 184.4, and width is unspecified.

Here's a sneak peek at the 2023 Acura Integra interior

Photos: Zac Palmer / Autoblog DAYTONA BEACH, Fla. — Acura staged its Integra Prototype at a display at the Rolex 24 at Daytona this weekend, inviting enterprising amateur and professional photographers alike to sneak a peak at the interior thanks to the bright Florida sun. The photos you're looking at here are ones we took at Rolex, and they essentially reveal what the 2023 Acura Integra's interior will look like. If you recall from the car's initial reveal, Acura did not show photos of the Prototype's interior. Before we dive too deep, though, we can tell that while the design appears to be final, some of the finer details are still a bit rough. Not all of the plastics, surfaces and badging look final, so don't expect everything you see here to directly port over to production. That said, this is still an awesome sneak peek at the upcoming Integra that we weren't expecting to get. From what we can see here, the interior design seems to take a cue from the Integra's underpinnings, which can be traced back to the sporty Honda Civic Si. Photos posted to integraforums.com show the prototype's dash before Acura's reps covered the upper portion to hide it from view. In them, you can see the mesh air vent design that debuted on the Civic, albeit with a different execution here (that treatment runs the full width of the dash in the Honda). Plus, the touchscreen infotainment rising from the dash is also in plain view. The seats look like Acura's latest seat style as opposed to Civic Si seats, and they even feature a neat two-tone black and white design. What does appear to be a direct Civic rip is the steering wheel, which gains an Acura badge and what looks like the rough outline of an A-Spec badge for Integra duty. We'll note that this likely means that the Integra will be offered in A-Spec trim, just like every other new Acura on sale today. The original Integra was never sold as an A-Spec in the U.S., but the RSX Type S (named Integra outside the U.S.) was available in A-Spec trim. Another difference between the Integra interior seen here versus the Civic is a new door panel design. Very little changes in the rear bench, though, as it's featuring the same drop-down armrest and pair of USB ports for rear occupants. The Integra Prototype is notably longer than a Civic Hatchback, but we didn't see any discernible increase in utility in the back.

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.
