2021 Acura TLX Long-Term Update | Tuneful turbo-four soundtrack

I used to be enamored with the turbocharged 2.0-liter engine format. I owned a 2004 Subaru WRX, with its turbo boxer mill, and liked it quite a bit, rough though it could be. Then turbo-fours, often displacing the same 2.0 liters, began replacing heavier and thirstier naturally aspirated V6 powerplants across the industry, and I was on board. Since then, they’ve become much more refined and responsive, all while their often uninspiring soundtracks faded into the background as automakers worked to improve the experience inside the cabin. TheyÂ’ve also become so ubiquitous that, apart from certain standouts like the turbo boxer in the Porsche 718, they ceased to be as exciting to me. Then AutoblogÂ’s long-term 2021 Acura TLX arrived in my driveway, equipped with a 2.0-liter turbo I4. I was excited about the styling and the handling, but I didnÂ’t expect this four-pot to make a huge impression on me. The first time I opened her up under wide-open throttle, though, I was pleasantly surprised. This 2.0TÂ’s 272 horsepower and 280 pound-feet of torque are ample motivation for this sporty sedan, even with all-wheel drive and a 3,990-pound curb weight. It wonÂ’t knock your hat into the back seat, but itÂ’s quick enough, especially in Sport mode. The thing that really won me over with this 2.0T, though, is the sound. Ripping to this thing's 6,800-rpm redline produces a melodious song that sounds a lot more exciting and expressive than most other fours. The cherry on top is the punctuated hiss of the turbo releasing its pressure when you get off the throttle. The amplitude of the engine note is manipulated using AcuraÂ’s Active Sound Control. As an Acura spokesperson explained it: “Active Sound Control uses the TLXÂ’s speakers (whether audio is playing or not) to add sound (same-phase or reverse-phase) to the cabin that smooths the sound of the engine heard inside the cabin. Engine noise doesn't increase in a linear way with rising revs; instead there can be many resonances that create peaks and valleys in the sound pressure level and an uneven sound. The level of ASC is tailored to each drive mode (Comfort, Normal and Sport).” Put another way, ASC is basically an electronic filter that can deaden or amplify the sound and smoothen it out, similar to how active suspension damping adjusts to the situation and drive modes to either let in more or less road feel, while actively eliminating the harshest of vibrations.

2021 Acura TLX Long-Term Update | Drive mode selector is a surprise delight

You may have seen last week my column espousing the sensory benefits of physical switchgear in cars. They can add a bit of fun and character in the smallest ways. As it turns out, our long-term Acura TLX has a great example of this idea: the drive mode selector. In most cars, drive modes are typically chosen via a nondescript button tucked away in the center console. Sometimes the selector is buried in an infotainment menu. But in the TLX, it’s a huge, gleaming knob placed front and center in the main control stack. It would be impossible to miss. ItÂ’s actually even more prominent than the buttons for shifting. 2021 Acura TLX A-Spec View 51 Photos With the size and placement, itÂ’s a nice dial to grasp, and works with smooth action and a solid stop in either direction for flipping through modes. But what really brings it together is the speed at which modes are selected, and the sound the infotainment system makes upon choosing one. In some cars it can take a long time for the system to acknowledge your selection and engage it, but the Acura activates it nearly as soon as youÂ’ve let the dial snap back to center. And it confirms your choice with sort of whoosh-y electronic clink through the speakers. ItÂ’s the kind of quick reaction and sound design you get from high-quality video game menus. All of these aspects make the TLX nicer to use and feel more premium. It doesnÂ’t feel like a hassle to change drive modes since it takes very little time and works well. ThatÂ’s especially welcome if you like driving it in the sport mode, since the car defaults to the normal mode on start-up. It also makes the car feel like it has fast-acting software befitting a premium car. It may seem like a small thing, but small things matter when cars have become so good. And I appreciate that Acura took its time with this seemingly little component. Related Video:

UPDATE: 2021 Acura RDX PMC Edition price set

The 2021 RDX is the latest in Acura's lineup to get the PMC Edition treatment. This limited-run, hand-built model follows the TLX and MDX PMC Editions and be finished in the same Thermal Orange Pearl that was pioneered on the NSX.  Blessedly, the "PMC in PMC Edition doesn't stand for pumpkin-anything. Rather, it's shorthand for the facility where just 360 examples of this crossover will be hand-assembled: Acura's Performance Manufacturing Center — the home of the Acura NSX — on Honda's Marysville, Ohio, campus. Each PMC Edition arrives in Marysville as a "body in white," ready to assemble and receive the paint process normally reserved for the NSX. The PMC Edition will be equipped similarly to an RDX with the A-Spec and Advance packages, with one exception: Acura's Super-Handling All-Wheel Drive system will be standard.  Otherwise, the PMC Edition is mechanically identical to the RDX, whose A-Spec already boasts a sporty exterior treatment to boot. The PMC Edition jazzes that up even further with gloss black wheels, a body-color grille surround, black chrome exhaust finishers, a gloss-black roof, gloss-black side mirrors and gloss-back door handles.  Inside, the theme is essentially inverted, with the black leather upholstery, steering wheel and floor mats all getting orange contrast elements. Apart from the serial number placard on the center console, the rest of the PMC Edition's interior is identical to that of a standard RDX equipped with the aforementioned packages.  Acura says the RDX PMC Edition will be priced at $51,000, with customer deliveries starting in October — just in time for jack-o-lantern season. Made you work for that one, didn't we?
