Cream_Filling posted:Yeah what is the AWD setup with the new CVT? I think the one on the upcoming Impreza is basically the same as the one on the current Legacy, right? Is it basically the same as the previous automatic? The Impreza is Subaru's closest version of an economy car and it wasn't very economical. The new, underpowered model is expecting 37 highway mpg, which is nearly 50% more than the previous model.

I'm fairly sure the AWD setup with the CVT is the same as the non-VTD automatics. It's fairly similar to haldax in function. When the clutchpack is fully open, it's very FWD biased. However, it's not as simple as only transferring power when slippage occurs, variable lockup happens depending on a whole slew of conditions. The VTD 5 speed automatics had the STi's AWD system (planetary gearset sets up an open diff torque split that's rear biased and a clutchpack varies lockup.) I do not know if they equip the VTD system on any of the automatics anymore (only the 3.0R comes with the 5 speed auto anymore.) Subaru doesn't call out VTD anymore so it's hard to say. The STi gets the same system as above, with manual adjustment of the lockup possible though DCCD. All other manual Subarus get a viscous coupling in the center diff. Default toque split is 50/50 with the viscous coupling providing power transfer based on front/rear driveshaft speed difference. On current models, all of that is coupled with VDC (vehicle dynamic control) and TCS (traction control system.) The new, lowered powered, Impreza with CVT is actually quicker to 60 than the outgoing 4 speed auto model. Part of that is due to the different power curve, part is due to the CVT making more efficient use of the power, and part is due to the fact that the 2012 Impreza is lighter than the outgoing model. What they are banking on is the MPG selling people. 36 mpg highway on a full time AWD vehicle is unheard of.

Yes the MPG number is important. I bet my dad will be happy with the new numbers, he was hoping for the diesel to come to the U.S. market but these numbers aren't bad at all in my opinion.

I hope Hyundai has it figured out, their new Accent seems like a fairly competent small car (so far).

Audi's 4.2 L FSI V8. This was at 43K miles, and wasn't among the worst the shop had seen. Unfortunately, the sister shop's dyno was unavailable, so we didn't get any numbers before/after cleaning. For what it's worth, though, my butt dyno did note an improvement. The Germans have been using it for a while, but they haven't solved this problem yet.

So the Camaro ZL1 officially ran the Nurburgring in 7:41.27 which is a few tenths of a second faster than the $120k Corvette ZR1. Granted the track conditions and driver don't make it a fair comparison, but jesus christ you will soon be able to go to a Chevy dealer and exchange about $60k for something that runs the 'ring faster than cars well over 2-3x its price. That time is competitive with a Lamborghini Gallardo Superleggera, Nissan GT-R, Zonda, etc. and pretty handily beats a lot of other exotics like the Ferrari F430 (10 seconds faster), etc. Between this and the news of a supercharged 5.8 liter Mustang GT500 I am super excited about American muscle cars. These cars are stupidly fast--let's hope people keep them on the road. edit: Video of the run: https://www.youtube.com/watch?v=8mhjGERugh0 God drat, what a fun looking ride. I do have to say its performance in the corners is more hold-on-for-dear-life-and-hoon-it-like-you-stole-it than carefree precision.  The car is definitely showing its limits with so much extra power.

The GT-R is all business through the turns with just a hint of drama. It almost looks like a leisurely Sunday drive compared to the ZL1: https://www.youtube.com/watch?v=dsXkkWI5MQE

FYI, there's a wikipedia page with all the nurburgring times. Radical SR8 LM has the street legal production car record at 6:48, nearly a full minute faster. A non-road-legal Zonda R did it in 6:47.50 (video!). The ZL1 is nowhere near the 7:20ish top times for GTR, Z06, ZR1 and Viper ACR. I always have to wonder what mods had been made and what tires all those cars were running, though. There's also a page with Top Gear track times. grover fucked around with this message at 13:15 on Oct 7, 2011 |

Mazda has been kind of wishy-washy on whether they're definitely continuing with Wankel development. I've never owned a rotary, but I've always been intrigued by the technology and have always kind of rooted for it just because it's different and an underdog. It's quite possible that the rotary hasn't blown it's last apex seal just yet.

Oh, and the SR8 that set that time was driven to the track. From the UK. Evo wrote it up as a feature back when it happened.

You get the impression that they're still very proud of the rotary (the entryway to the HQ has its own little shrine to them), I can't see them nailing that coffin lid down any sooner than they absolutely have to.

Everything I've read before had said they are continuing development, but mostly as a side project. If it's actively being worked on that's cool. I hope that they can make an emissions friendly fuel efficient model, but at this point I'd be surprised.

They were working on a hydrogen fueled rotary, but I don't know if that will ever be commercially viable. Especially with the latest direct injection turbo engines giving good economy and power in a relatively small package.

It's my understanding that most of the team working on the 16X were moved over to the Skyactiv team, but development on the former still continues at a slow pace.

If there were some crazy alternate reality where NASCAR used cars that were closer to production vehicles and raced on real tracks with left and right turns it would look something like this: https://www.youtube.com/watch?v=SFdHJRG0jsA That alternate reality is Australia and drat if V8 supercar racing isn't awesome.

Mazda should have never offered the RX-8 with an automatic. This isn't just manual transmission snobbery; I actually think that decision did a lot of harm to the public image of rotary engines.
