A Car and Driver article recently featured the new Mercedes 320 Turbo Diesel in the '05 E320 CDI. It has 221 hp and 376 lb/ft and common rail direct injection. They set 3 world and 22 international records. "... Armed with a diesel v-6 that thinks it's a gas v-8, Mercedes decided to set some high speed distance records. Most notable would have to be running 100,000 miles at an average speed of 139.699 mph. That acheivement means driving 24 hours a day for 30 days, which subsequently required 26 mechanics and engineers and three teams of six drivers, with each driver taking the wheel for intervals of about 2 hours and 10 minutes. In the course of the 100,000 mile runs, each team performed 322 pitstops,, 10 services (Changes of oil, and oil, air and fuel filters), and 25 tire-set swaps. ...The three E-class sedans ran into nary a problem and returned an impressive 17 mpg."
