2016 CTS-V revealed

Post by kevm14 »

And believe it or not, a casual visit to Jalopnik this morning broke the news to me.

http://jalopnik.com/2016-cadillac-cts-v ... 1673973826

The CTS-V is all grown up.

LT4 and 8L90 is all we know so far. So the ATS-V has no LT1 and this car has no manual. Perhaps a 2015 Chevy SS w/ manual is in my future someday. Or, hell, a 2014 with 6L80.

Shipping with the Michelin PSS!

Thoughts on whether they should produce a wagon:
the wagon was terribly executed as a utility vehicle. I wanted to get one, but my wife vetoed when even she had no leg or head room in the back seat. I couldn't believe how bad the car was at being a people mover - which it kind of has to be if you're going to buy this over a sports car. Did anybody else find this a problem? I always felt this was the biggest reason the wagon didn't sell.
Fair enough. So they SHOULD, but try to avoid compromising interior space as much for the sake of styling.

So 640hp (up 84hp from the V2) and it has to be lighter than the V2. This ought to run 11s off the showroom floor.

Yes, the Hellcat will be faster.

Perhaps Bob can explain this.
◾A revised multi-link double-pivot MacPherson-strut front suspension delivers a quicker response and increased lateral control, incorporating “hydro” bushings, where traditional elastomeric bushings are replaced with zero-compliance cross-axis ball joints
Ball joints instead of bushings? What? Double-pivot strut? Is that like the 4th gen F-body?

GM says:
MacPherson-type with dual lower ball joints and direct-acting stabilizer bar
I need a pic. Maybe Edmunds will do a suspension piece on this car, eventually.

Wow, huge props to GM for sticking with 19s. It underscores their dedication to real performance (the V2 also ran 19s).

Fronts are 265/35ZR19 and rears are 295/30ZR19. That reminds me of the C5 Z06 sizes, just with larger wheels.

So 640 HP @ 6400 RPM and 630 LB-FT @ 3600 RPM, SAE certified.

Compare to the LSA at 556 HP @ 6100 RPM and 551 LB-FT @ 3800 RPM (also SAE certified).

The LT4 also has a bit higher redline (6600rpm). 10.0:1 compression.

The 8L90 has quite a ratio spread, at 7.02x. A 4L60 is 4.40x. The 6L80/90 is 6.04x.

The ZF 8HP is 7.07x for comparison.

Fun trivia: The CTS Vsport, at least the first year of it so far, uses the Aisin AA80E, http://en.wikipedia.org/wiki/Toyota_A_t ... sion#AA80E

Shares applications with:
2007-present Lexus LS 460
2008-2011 Lexus GS 460
2008-present Lexus IS-F
2009-2013 Toyota Crown Majesta

That one has a ratio spread of 6.71x.

Just to be clear, the actual ratios don't matter unless you are retrofitting. You just gear the diff accordingly. A higher spread means you can have a comparatively steeper first and taller top gear. Speaking of which, the 2016 CTS-V uses a 2.85 rear diff ratio. 8th gear is 0.65 which is a bit taller than a 4L60, which will give this car pretty low cruising RPMs.

Steering ratio looks great.
15.5 (on center) to 11.2 (full lock)
Not too fast on center but speeds up a lot off center.

Brakes. Fronts a little bigger than previous gen.
Fronts are 15.35 x 1.41, two piece. 6-piston
Rears are 14.37 x 1.10. 4-piston

V2 had:
2009-2012 front: 14.6 x 1.26
2013 + front: 14.96 x 1.26. 6-piston
Rear: 14.37 x 1.10. 4-piston

The V2 also offered some kind of 2-piece upgrade starting in 2013 (this was standard), which apparently made a very large difference in braking performance (cooling in track conditions). I need to confirm that the size actually changed. I don't recall reading about that.

V1 had:
Front: 13.97 x 1.3. 4-piston
Rear: 14.37 x 1.10. 4-piston

Weight and bias

V3: 4,145 lbs with 52.7% front (GM spec)
V2: 4,292 lbs with 54%-ish front (varies, two transmissions, GM spec vs review measurements)
V1: 3,850 lbs with 54% front
