2017 civic si
"Compared to the closely related 6-speed manual transmission offered in the Civic EX-T, the Si transmission has more rigid bracket mounts to match the engine's higher horsepower and torque. Refinements to the shift linkage and selector mechanism produce a precise and smooth gear lever shift action while reducing stroke by 10 percent."

So a slightly better shifter.

Heh, was just going to post that exact same quote... :)
Yeah that sounds like very good news.


They also clarified which suspension bits are shared with CTR - it's all in the rear, as was speculated here earlier:

Compared to the overall Civic model range, the new Civic Si rear suspension has the following differences:
  • 32-percent stiffer spring rate
  • Solid front and rear compliance bushings (rear shared with Civic Type R)
  • Adaptive Damper System (ADS)
  • High-stiffness upper control arms – common with Civic Type R
  • 26-percent stiffer stabilizer bar rate

Oh and the spare tire option also officially confirmed!

In addition, a T125/70R17 space- and weight-saving temporary spare tire is available.

New-generation "2.0" SiriusXM® Radio*
I hope this is the same system I have in my '17 Ridgeline that is capable of receiving SiriusXM's Xtra channels. I listen to Utopia, which was moved from channel 55 to channel 341. Relatively few receivers can receive the Xtra channels. The 2016 Civic press release advertised SiriusXM 2.0, but my brother's '16 Touring was unable to tune to the higher Xtra channels.

Variable Displacement Compressor (VDC)
Thank goodness! A rare animal for Honda (and most other brands these days), this has actually been standard on all Civic since the 2016 model year. GM, in particular, used to use a lot of VDCs, but they largely fell out of favor due to cost and complexity. Unlike a cycling compressor, the clutch on a VDC remains engaged while the compressor varies its displacement. Cycling compressors have always bothered me - especially at idle - due their abrupt on/off action every several seconds. A VDC reduces compressor clutch wear and provides for a more stabile evaporator temperature.

Steering is also different on the Si as opposed to the standard Civic. I think the sum of the details put into the chassis is going to make the Si feel very different from the standard Civic.

See, there's a 2.0 in there somewhere...

Finally, they show the wheel width as 8.0" for the standard 18" wheels. Also, in the accessories section it shows a 19" black HFP wheel. However the 19" option isn't available when building the car online. I wonder if it's only available as a "dealer-installed" option.

There's an error in the interior section. This is not a standard feature, although it is available an an extra-cost accessory that unfortunately requires disassembling the interior trim and instrument panel in order to run the wiring. I've installed these accessory mirrors in previous Hondas where the wiring was already present behind the overhead console, but I'm not interested in disassembling the headliner, A-pillar, kick panel, and instrument panel in this case.

Both the 18" accessory wheel and 19" HFP wheel are dealer-installed items. The 19" wheel requires new tires as well - probably 235/35R19 to maintain approximately the same diameter. Also, it's almost impossible to find all-season tires in this size - the vast majority are Summer tires.

It's not like the old days anymore...go to the junk yard, find the accessories you don't have-pop out the blanks on your car and bam! Factory harness plug already there:thumbsup:

I have always wondered that when you get accessory wheels do they gave you the stock wheels/tires back as well? If not then what a huge rip off! You can get better than OEM grade/lighter wheels for much cheaper.

You have options:

1) Take the stock wheels/tires with you since they are yours to keep or sell.
2) Give them to the dealer.
2a) The dealer or a dealer employee may buy them from you (but, probably not).
2b) The dealer might actually charge you a tire disposal fee for "getting rid of them" (read: an employee takes them home or the dealer sells them to someone else).

Thanks! I will likely get new lighter 18s and sell the stocks. Have done this with all of my cars. Can't even begin to tell you how much difference lighter wheels make in braking/handling/accelerating. One the best upgrades you can make!
