Well, there’s been a couple of threads on this very topic. Here’s one of them:
Accord Vs TLX 2021
In your case, it’s a bit different since you’re going from an HAH. My question for you… how much do you care about mpg vs performance? Sound system? Do you need AWD?
When you say it’s not giving you much better mpg, what do you mean exactly? 40mpg combined? 35 mpg? Even at 35 MPG, that’s going to be much better combined mileage than either the Accord 2.0t or TLX unless you do strictly highway driving.
If you’ve already narrowed down to these two options, I’d consider these:
TLX
Pros
1) Better interior quality (as it should be)
2) Much better sound system
3) Better handling (Accord’s not bad either)
4) Optional AWD
5) Longer standard / basic warranty
Cons
1) Tiny backseat & smaller trunks
2) Worse gas mileage by a bit
3) much heavier weight - slightly slower acceleration, although if you’re looking at Touring they might be real close, like within .2 or so 0-60
4) Obviously higher MSRP
To me, the biggest differentiators between the two are TLX’s superior sound system and SH-AWD. If you don’t care much for either and can get both cars for MSRP, I’d get the Accord. But like it was mentioned, I’d probably hold on to the HAH especially given the current gas situation.
