The .6 has a lockup torque converter, it ought to be capable of better mileage. Diesels aren't as sensitive to engine RPM, so the number of gears, and their ratios, should be largely irrelevant to overall efficiency. My _guess_ would have been the 98, due to the turbo and the LTC. If it's not, and it's real, it's probably something to do with emissions equipment, as you suspect. The other choice is that they changed how the test is conducted, which is a factor _not_ to be discounted! In which case the difference is not real. -- Jim _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
