Pole Position
http://www.insideline.com/infiniti/m...and-video.html
GS350 has higher 1/4 mile trap speed 99.9mph vs the Infiniti M37S 99.0mph
slightly better skidpad : 0.88g vs 0.86 g for the M37S
Most crucially, it has significantly faster slalom speed (a test of chassis balance and ability to perform quick transitions) : 69.7mph vs 67.9mph
Also, if you're interested, here are 4 comparison tests where the current Lexus GS has beaten the current Infiniti M :

This is on topic. We're discussing whether the 4GS chassis is actually any good for the new IS which shares that chassis. Comparing the 4GS to its competition gives a hint at how the new IS will perform next to its competition.

discussing whether 4gs chassis has an impact on the 3is, yes. we never tried to stop that. arguing 4gs performance with other competitors, no. and that's why F1Drive was asked to exit the thread. davegs4 made it clear, bitkahuna made it clear, and i did.

I wonder if the next IS cabriolet will actually be based on the production version of the LF-CC or remain primarily based on what I presume to be the IS "XE30" chassis? Seeing it up close rather than in pictures really showed how much bigger it is and is almost the length of an E-Class coupe(though C-Class-based). In other words, will the next IS cabriolet share the same platform as the coupe or remain an IS-C?

Mid-size is term used in Europe for cars of IS size... it is not bigger.

Toyota Working On Turbo Hybrid Drivetrain For 2014 Lexus IS
The next Lexus IS is set to appear in late 2013 as a 2014 model. We’ve seen spy photos of the new car in testing, and we’ve previously reported that the car will be both sportier and more upscale than the version it replaces.
We know that a hybrid version is in the works, too, although we haven’t had much detail to bring you so far. Now, Auto Motor und Sport is reporting that the IS 250h will come to market with a turbocharged, direct-injected 2.5-liter Atkinson cycle engine, said to be good for 200 horsepower.
More impressive, however, are the car’s fuel economy gains: compared to the current IS 250, which sucks down 8.4 liters per 100 kilometers in Euro-cycle testing (the equivalent of 28 mpg), the new car will use just 4.2 liters per 100 kilometers (the equivalent of 56 mpg).
If those numbers sound like diesel fuel economy claims to you, there’s good reason: to increase efficiency under partial engine loads, intake valves have a delayed closing. This results in thermal efficiencies very similar to diesel engines, but with lower emissions.
As a reminder, Euro-cycle test numbers can be up to 30-percent optimistic compared to our own EPA estimates. Factoring that in to the equation, a 200-horsepower Lexus IS 250h that achieved a combined fuel economy over 39 mpg would still be impressive.
Forced-induction hybrids appear to be the future direction for Japanese automakers. Just yesterday, we told you about the supercharged 2.5-liter four-cylinder hybrid drivetrain that Nissan is developing for its Infiniti brand, expected to debut in the upcoming Infiniti JX Hybrid.

^The Camry 2.5 hybrid already makes 200hp, without turbo or DI!! A new 2.5 turbo-DI hybrid making 200hp would be downright pathetic. The whole article must've been made up out of thin air

At the moment, I'm just worried the next generation IS will have a 4 cylinder engine, the wonderful 2.5 V6 will be deleted, while the 3.5 V6 is a bit too big as a regular engine for this size of car, and the standard model suspension will still be too firm?
I'm not sure if they'll get the styling right either; Lexus is so inconsistent when it comes to styling.
We'll just have to wait and see.
I'm not keen on switching over to a Benz or Beamer for my wife...
