Hondata's 2019 Acura RDX tune brings the mid-range torque

One of the big advantages to the era of turbo Hondas is that there's plenty of horsepower and torque left on the table for tuners to take advantage of. One of those companies is Hondata, and following its upgrades for the Civic and Accord, it's now tuning the Acura RDX luxury crossover. The RDX uses a turbocharged 2.0-liter engine similar to those in the Accord and the Civic Type R. In stock form, it makes 272 horsepower and 280 pound-feet of torque. With Hondata's Stage 1 tune, the company says that horsepower increases by about 10 across the rev band. Looking at the dyno graph, it also appears that peak horsepower increases by about 5 horsepower, and peak torque is up by about 15 pound-feet. Peak torque also appears to arrive sooner, and most of the torque curve seems to be up by 10 to 15 pound-feet. The increases in power and torque are available in all four of the RDX's drive modes. The Stage 2 tune increases power torque even more in Sport and Sport+ modes, and keeps Snow and Comfort modes at Stage 1 settings. Peak horsepower looks to be up about 10 over stock, but the mid-range sees as much as a 28-hp increase. Peak torque sees a huge jump of about 45 lb-ft over stock based on the dyno chart, and it's available even lower than the Stage 1's peak torque. If this all sounds good to you, you can order up a Hondata FlashPro computer for your RDX right now. It costs $695 and comes with the handheld computer for uploading or removing tunes. RDX owners in California should note that neither tune is currently CARB legal. Related Video:

Acura reveals performance EV concept called Performance EV Concept

After teasing a new EV concept for Monterey, Acura made good on its promise Thursday with the unveiling of its rather plainly named Performance EV Concept. Good news: Acura's first in-house EV will be a performance car. Bad news: It's not the one we all hoped it would be. Instead, we're getting another model in the grand tradition of the ZDX — pronounced front end and all. It seems that look is here to stay, so get used to it, because Acura says it plans to build a production model based on this concept starting in late 2025.  That's noteworthy not just because this is Acura's first in-house EV, but because it'll be the first production car to ride on any variant of Honda's new BEV architecture. The mainstream brand is planning to put something based on its 0 Series "Saloon" concept into production in 2026. That's quite the coup (no "e") for Acura, which spent most of the past two years talking about the Ultium-based ZDX project, which by all accounts will be the first and last Acura-badged product of Honda's tie-up with General Motors and its Ultium EV platform.  As you can probably surmise, Acura remains tight-lipped about specifics. Honda (and by extension, Acura) "concept" vehicles have a funny habit of being put into production almost exactly as they sit, so what you see here is likely pretty close to the mystery CUV's final physical form, but battery and motor specs remain nebulous for the time being. We expect a multi-motor setup engineered to mimic the behavior of the SH-AWD system Acura offers in its ICE vehicles. The concept's massive 23-inch wheels encircle a set of four-piston calipers and crossed-drilled rotors — the two most significant hints that we're looking at something meant to move quickly.  If you're in Northern California for Car Week, you can check out Acura's concept at The Quail. The company's presentation is scheduled for 10:36 a.m. local time (What is this, a train schedule?) on Friday. 

2021 Acura TLX A-Spec Long-Term Update | Infotainment system hits a pothole

The first few thousand miles of motoring in our 2021 Acura TLX A-Spec long-term test car were problem-free, but that changed after we took it on a spirited drive through the winding hills of southern Indiana. You can read about how it handled a full day of thrashing here, but this story will focus on the dead infotainment system previewed in the headline. About halfway through the twisty route, every sizable pothole or big bump in the road would cause the infotainment system to black out. A message would appear declaring “MOST NET LOSS,” and it would quickly dip to black after that. The next big pothole would cause it to flicker back on, but it never remained on for any long periods of time after this. In addition to the screen loss, the speakers would make some rather disturbing crackling noises. This continued throughout the day and for several days beyond that. If the roads I was driving on were flat or devoid of major problems, the infotainment system would generally be fine. It took a major jostling of the carÂ’s bones to cause it to act up, but Michigan provided enough of those to make the problem exceedingly annoying in a hurry. So, to the dealership it went. 2021 Acura TLX A-Spec View 51 Photos After the local dealer looked it over, they said there was a TSB out for this issue, and that theyÂ’ve seen it pop up on other RDXs and TLXs already. Turns out, there are a number of wire connectors between the infotainment system and wiring harness that are causing the problems and coming loose. The fix? Newly designed connectors from Acura, plus the wiring harness is ever so slightly freed up to allow for a bit of movement from violent impacts. Doing this (plus using the stronger new connectors) should ensure that the stress on these connectors is never so great as to cause issues again.  The job was completed under warranty and took a full day from diagnosis to the return of the car. WeÂ’ve put several hundred miles on the car since the fix, and theyÂ’ve been completely trouble-free — it sure was nice to listen to AcuraÂ’s excellent ELS audio system again. That said, this issue is one weÂ’ll follow closely to see if AcuraÂ’s fix truly is a long-term solution. WeÂ’ll have a deeper dive on how AcuraÂ’s TouchPad infotainment system works (now that itÂ’s actually working again) soon, so watch out for that update in the near future.
