6MT's LSD worthless?
https://www.caranddriver.com/acura/integra-2023
Car and Driver's handling measurements seem to suggest the LSD in the 6MT version of the Integra is somewhat worthless. The heavier CVT version (coming in at 3144 lbs) pulled 0.90g on the skidpad, while the 6MT (at 3062 lbs) could only manage 0.88g. If the LSD was implemented correctly on the Integra then it should clearly translate to better testing numbers than the car without it, but that doesn't appear to be the case here.
A MotorTrend review seems to corroborate the theory when it says the following:
So it seems AHM mucked up the 6MT Integra with bad software (i.e. - traction control) effectively negating all positives the car should get from the LSD -- effectively reducing the it to just another marketing buzzword. I guess that really should come as no surprise because AHM has made numerous stupid choices on/for the Integra!

A MotorTrend review seems to corroborate the theory when it says the following:
The Integra's 0.87-g skidpad average is about what's expected for the class, but the Acura's figure-eight time of 27.2 seconds at 0.63 g average doesn't impress, considering its rivals run the lap in the 26-second range. Our test team was frustrated by meddling traction control, which never seems to truly turn off and prevents full power unless the steering wheel is straight. Such interference negates the differential's benefit in on-limit driving.
Out on the road, the Integra is willing to play up to a point. Its tidy size and weight let it flow between corners, but the verve it initially presents evaporates if you ask too much of it. Instead, the Integra becomes overwhelmed by understeer and imprecision. Truly sporty cars come across as a vivid conduit between driver and road—the new Integra doesn't.

Sadly, I found more numbers to substantiate that the LSD is effectively worthless (at least when cornering) in the 6MT.
MotorTrend's numbers for a 2023 CVT Integra:
AHM should quite frankly be totally ashamed of themselves for allowing this abomination to come to fruition!
MotorTrend's numbers for a 2023 CVT Integra:
LATERAL ACCELERATION: 0.92 g
FIGURE EIGHT: 26.6 sec @ 0.67 g
And for a 2023 6MT Integra:FIGURE EIGHT: 26.6 sec @ 0.67 g
LATERAL ACCELERATION: 0.87 g
FIGURE EIGHT: 27.2 sec @ 0.63 g
FIGURE EIGHT: 27.2 sec @ 0.63 g

Having AutoX'd the Integra, I can tell you that the LSD absolutely works...if you fully disable traction control via the "pedal dance". With traction control on (or even in the factory "off" setting) it cuts power before the inside wheel spins, therefore neutering the effect of the LSD. Same thing with the Civic Si.

Are you sure about that? MotorTrend's numbers for a 2025 SI are 0.94g and 26.1sec for the figure-eight -- those numbers are better than the 6MT Teg (and even better than the CVT -- which inexplicably bests the 6MT). I suspect AHM started with the traction control software that they had for the Si, and tweaked it the Integra to account for the fact this model has a CVT. In doing so they appear to have optimized it for the CVT while effectively nullifying the LSD in the 6MT. I'm sure it was a matter AHM wanting to do things as cheap as possible; that is why the Integra -- supposedly a luxury model -- doesn't have an acoustic laminate windshield, wheel resonators, or real leather seating despite all them being available on the much cheaper Civic.

Google?
The Civic Si numbers are better because it comes with better tires. It was tested with Goodyear Eagle F1 Asym 2 summer tires. The Integra comes with ContiProContacts all-seasons, which are usually decent but these OE version were absolute dogshit. Mine would spin WOT in 2nd gear.

No doubt the summer tires would make the numbers for the Si better, but maybe that isn't all of it? I still find it very odd -- actually a travesty -- that both C&D and MT found the CVT equipped Integra actually handles better than the 6MT one (that has a LSD for crying out loud).
Actually I just found some familiar MT comments on the 2022 Si (that they didn't mention in this 2025 review):
"Likely the biggest issue is the stability control, which is never fully off and won't give you full power until the steering wheel is completely straight, despite the standard limited-slip front differential."
That sounds about the same as their gripes on Integra actually.
So very, very strange that AHM decided to include LSDs on these cars only to effectively disable all its benefits with the traction control software. And just as strange that the seemingly were able to make traction control software work so well with the Integra's CVT tranny that it handles better even though it has no LSD.

MT got these number for the 2023 Accord Touring:
LATERAL ACCELERATION 0.87 g
FIGURE EIGHT 27.1 sec @ 0.65 g
Pretty shocking that a big ol' Accord Hybrid can match (or slightly best depending on how you look at it) an Integra with a LSD -- just shows how much they mucked-up the 6MT Teg. Trending Topics

@fiatlux
Last night I was thinking that those testing numbers really only represent one scenario that's basically "at the limit" so it's not a full picture of the handling of the car. It is still sad to see the CVT model post notably better numbers than the LSD equipped 6MT one. And with two different magazines (LOL do they even print them anymore?) coming up with the same results, I don't buy your new/old tire theory -- just seems way too unlikely. And I am so critical of AHM precisely because I've been a fanboy so long! I just wish they would have actually committed to the new Integra instead using it as a stop-gap; too many of their poor decisions point the model being short-lived. Maybe if they hadn't wasted so much R&D money in the last TLX things would have been better for the Teg
