I don't believe 12.9's would be possible still.
Keep in mind, though the xi can launch hard, it has an additional 250 lbs to haul around, AND has additional drivetrain losses (and slightly worse aerodynamics too).
So where a best possible stock 335i time of say 13.2x @ 105+ mph might be possible, the 335xi will lose most of what it gained in the first 1/8th mile from it's launch in the last 1/8th mile because of it's weight and extra drivetrain losses.
At a VERY fast track with nice cold upper 40's temps with DA's below sea level I think both the 335i and 335xi are capable of low 13.2's but where the 335i might have trap speeds in the 105 mph range, the 335xi will be in the 103-104 mph range.
In an 1/8th mile track I'd give the xi a .2-.3 second advantage
I think the 13.3's that some people (and a magazine too I believe) have gotten are going to be in the top 10% of times. And even that requires a very good track with good weather conditions and a car that runs on the strong side of average (and a very good driver if it's a manual).
I'd say for most people at most tracks with decent weather, or I should just say the "average" for a stock 335i would be
13.4-13.5 @ 104-105 mph (add a tenth or so for manual transmission since they are harder to launch and usually don't do as well.)
