Here is at least a possible answer to the timing chain question. It is looking like the U.S. market could get a version of this Z-series diesel instead of the VCDi. Although most of the information is still based on info coming coming from the Indian market. It does seem to have better performance, (0-62 mph in 8.5 seconds vs, 9.4) but still no mention of gas mileage.
