We already knew that purchasers of VW's new clean diesel-powered Jetta for 2009 would be eligible for a tax credit of $1,300, and now more models from Germany get the same treatment from the Internal Revenue Service. All Mercedes-Benz models equipped with the BLUETEC emissions treatment technology will get a rebate. The 2009 GL320, R320 and ML320 BLUETEC are expected to go on sale beginning in October of this year, which should give prospective buyers plenty of time to get ready to prepare for the savings on their taxes. Each of the vehicles will get a different rebate ranging from $900 for the ML to $1,800 for the GL due to the process the IRS uses to determine how much fuel will be saved by the vehicle. As with other similar systems, each manufacturer is limited to 60,000 units sold before the rebates come to an end.

In another of the ongoing rounds between diesel versus hybrid we bring you two heavyweight contenders, the Chevy Tahoe hybrid, which we had in the AutoblogGreen garage, versus the Mercedes-Benz GL320 CDI. Actually, it's brought to you by the good folks at Edmunds who took it upon themselves to give these two a through shakedown. As I'm sure you've already noticed, these are two humongous SUVs that we don't consider especially green but for those folks who need to tow large trailered objects or haul large families they are relatively more green than their forebears.

The competition between these two was pretty tight for a while. Pricewise, the Mercedes was only $480 more than the Chevy for the base model though the Chevy became a pretty good bargain once the options came into play. Both of the beasts excelled at acceleration (8.5 second, 0-60) with the Tahoe ahead by the slimmest of whiskers as long as they traveled in a straight line. With the cones set up, the Mercedes superior agility really shone, whipping through the course at 60 mph while the Tahoe had more waddle than a flock of ducks on the hoof. Also, in the all important fuel economy category, the diesel pulled decisively ahead, at one point returning 26 mpg during a stretch of highway driving where the Tahoe could "only" eke out a 21.9 figure over that same stretch. Advantage diesel. To watch these two duke it out auto à auto, hit the jump.
