2023 Acura Integra production specs and photos revealed

We have waited five months since the Integra Prototype was revealed, and now what we’ve been long awaiting is finally here. This is the 2023 Acura Integra in final production form. Today not only gives us photos of the Integra in its final guise, but Acura also dropped all the information and details weÂ’ve been anticipating. LetÂ’s dig in. Per usual with Acura Prototype models, the production version mirrors the prototype closely. The obvious prototype elements are gone, like the big “Integra” side graphic and color exhaust inserts, but most of what we saw last year remains on this hatchback. One notable omission is the lack of photos with the yellow exterior paint Acura launched the Prototype in. A leak of the available paint colors suggested that yellow wasnÂ’t on the table for initial launch, but that doesnÂ’t mean Acura wonÂ’t introduce it as an option down the road. Just as was teased in the Proto, the only available engine will be a 1.5-liter turbocharged four-cylinder, and itÂ’ll be officially rated at 200 horsepower and 192 pound-feet of torque (same output as the new Civic Si). A six-speed manual transmission with auto rev-matching will be available on the A-Spec model, but a continuously variable transmission (CVT) will be standard across the line. The CVT features “Step Shift” programming to simulate shifts, and also allows you to move the engine speed around with paddle shifters. We wouldÂ’ve loved to see Acura figure out a way to use its 10-speed automatic in the Civic platform, but alas, the CivicÂ’s CVT will be the only automatic option here. If you choose the six-speed manual — which we strongly suggest you do — the Integra gains a helical limited-slip differential that is not equipped to automatic cars. Delving further into the performance realm, the Integra gets an optional adaptive damper system. If you recall, Honda dropped the adaptive dampers from this generation of Civic Si, making it a reason to upgrade to an Integra. The adaptive dampers have three settings: Comfort, Normal and Sport. Similar to other Acura models, the Integra features various drive modes to adjust throttle response, automatic transmission mapping, steering feel and gauge coloration. If you get the “A-Spec with Technology Package” model, an Individual mode is added that allows you to independently change all the modes separate from one another. It also adds an option to change the in-cabin sound.

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 announces NSX GT3 Evo22 race car will live on

The Acura NSX may be winding down production in 2022, but it still has some life left on the track. Today, Acura announced that it will introduce a new version of its NSX GT3 race car. It features a slew of improvements that should make the platform more competitive. Called the NSX GT3 Evo22, it builds upon the existing NSX GT3 a car that has won multiple championships in IMSA, SRO and Japan's SuperGT. The Evo22 gets improved intercoolers for the 3.5-liter twin-turbo shared with the road car, allowing it to perform consistently in a wider range of conditions and locations. Underneath, the suspension earns some tweaks in revised spring rates and geometry adjustments. To improve the car for endurance racing, the Evo22 reduces pit time with larger fluid tanks, while a revised wheel system allows for quicker tire changes. An FIA-mandated rain light illuminates the rear. Acura will also offer several air conditioning and headlight options. As with the outgoing NSX GT3, the Evo22 eschews the road car's hybrid and all-wheel-drive systems. Instead, it employs an XTRAC semi-automatic six-speed sequential transmission to send power to the rear wheels. Both the race and road car, however, share the same specs for the engine block, heads, valvetrain, crankshaft, pistons, and dry-sump lubrication system. The motors and chassis are both built at Acura's Performance Manufacturing Center in Ohio, while final assembly for the GT3 takes place in Milan, Italy. While European GT3s are supported from Italy, Honda Performance Division in Southern California will support North American teams. The NSX GT3 is the defending IMSA GTD and SRO GT Manufacturers’ Champion, and has achieved 25 IMSA and SRO class wins since its North American introduction in 2017. Interestingly, Acura says the the NSX GT3 is homologated globally through 2024. So, while new road cars won't be produced after next year, you'll still see them representing the "A" calipers at the track beyond that.
