2016 ILX A-Spec 0-60 and 1/4 mile numbers    (Score: 1, Normal) 05-25-2015 16:37
Reply to This Message Attach Quote to Reply
I've had a 2016 ILX A-Spec for the past week and only today have I managed to get out and get some testing done.

I would have done it earlier but it was delivered to me with something like 31 miles on the odometer and I wanted to break it in a bit before putting it through the stress of acceleration testing.

This week was crazy busy for me so I really didn't get to drive it as much as I normally do, nor as much as I'd like to.

Anyhow, as my first impressions indicated, even though it's considerably lighter than the 8DCT 2.4 TLX it's not really any quicker, thanks in large part to the taller gearing.

My very first pass turned out to be the best, and the numbers were actually pretty impressive, but I was unable to back them up on any subsequent tries. Looking back, on that launch I had the most wheelspin, so I think that's the key to getting good times out of it. On that single GOLDEN run, I recorded a 0-60 of 6.5 seconds, 1/4 mile of 15.4@93.4 mph. 60' time was 2.5seconds, so not a fantastic launch but I guess the wheelspin let it get up through the "boggy" part of 1st gear into the more meaty part of the torque band.

All of the other runs were in the 7.0 range for the 0-60. The worst was 7.4 seconds, but I only clocked that once. I had several at 7.0 and a few more at 7.2. All runs were performed in Sport mode with VSA disabled. Certainly with a shorter first gear or a more aggressive launch this car will deliver better numbers. The temps were cooler when I tested the TLX so that gave the TLX a bit of an advantage in terms of power, and if it were cooler out the ILX would likely spin the tires a bit more easily and that would help it. It won't surprise me if the non A-spec trim with the 17" wheels records better 0-60 times.

The ILX is plenty quick but for $35k, I think to be a serious contender in its class the 0-60 and 1/4 mile numbers should be at least a second better, so the performance hurts the value proposition of the ILX a bit. It should feel more energetic than the TLX but it just doesn't quite pull it off.

Thanks Jeff!

What tires does the A-spec model come with?

I thought that sort of performance is reasonable. Was hoping for a bit better but I guess the gearing is an issue. I don't know why with 8 gears, Honda still had to mess this up...lol...

thanks for the quick review, I also suspect the integrated exhaust manifold with close coupled cat designs tends to increase underhood temps more rapidly which then degrades performance numbers.

It has Continental ContiProContact P225/40-R18.

The tires are pretty good - it started raining today for the first time all week and the wheelspin from a launch on wet roads is roughly the same as on dry. Even with VSA disabled...

I wonder how much loss that torque converter contributes. It was a question that Hargett stumbled on pretty badly. Most likely he just didn't know, but maybe he knew and didn't want to disclose that information.

I would have expected it to average noticeably quicker times than the TLX given the weight difference. I wonder if there are gearing differences as well.

Yes there are considerable gearing differences. Which is why I referenced the gearing differences in the post at the top of the thread. The ILX has taller gearing than the TLX.

Also, perhaps Acura tuned the ILX's torque converter a bit more conservatively than the TLX's as well. Or this one was just a bit tighter due to only having 215 miles on it.

According to acura.com, final drive ratio for TLX 8DCT is 4.57, and ILX 3.94.

All of the 8 gears have the same ratio.

They should do the ILX to 5 in the final drive ratio, 3 complete gears for 62mph would not be bad.

Considering it's locked up after 1st gear and only unlocks during shifts, I can't imagine it contributes anywhere near the loss of that on a normal automatic.

actually the torque converter should make for stronger launches thanks to its inherent torque multiplication effects, but it depends upon how they tune the stall speed. The biggest issue I see with the 0-60 times is the ILX's taller final drive and relatively soft launch.

I think this drivetrain combo is excellent for a base ILX. However, I'd really like to see Acura give the ILX a drivetrain spread similar to the Audi A3.

ILX FWD 201hp 2.4/8DCT - A3 FWD 1.8t
ILX AWD 240hp 2.0t/9AT - A3 Quattro 2.0t
ILX AWD 305hp 2.0t/9AT - S3 Quattro 2.0t

*The 9AT's programming would have to be seriously upgraded.

Here's a video of the gauges during an acceleration run. This wasn't on one of the timed runs, thus it isn't dead level ground (in fact it may be slightly uphill) but it's close enough for the purposes of seeing how the car launches and shifts during an acceleration run.

When I test drove it, I noticed, the torque converter does not fully lock under cruising conditions, there was still some rpm float on mild throttle lift and input. It does lock on full acceleration after the first few mph though. I would consider the car to replace my wife's Civic EX but not my '09 Si.

Thanks for the video Jeff. It sounds pretty good.

Here's a video of the A3 1.8T accelerating by comparison:

I think the ILX sounds better but that's just my opinion.

My TSX does that :) I like it. I love the TSX's 5AT... A bit wide though..

In fact, setting final drive ratio to 5 would give numbers:

They definitely did a good job of tuning the sound. It sounds good. You can tell it dies off a little at the top, but overall, it seems like it pulls pretty well in the top end.

I wasn't going to say it. But then again, that isn't an automatic Honda complaint exclusive to this car either. Honda has long programmed their auto cars to shift well before redline (when stock my 1990 Accord would shift around 5800-5900 even though redline was 6250.

Even the J30 7th gen Accords we had would shift at 6000 or so, even though they had an extra 500RPM they wanted. It is probably one of the reasons they didn't put the dual stage IM on those engines.

Even the 2013 shifts just shy of redline.

One of the infuriating reasons I prefer MT Honda products. They build revvy engines and then don't let them rev.
