Hold onto your cognac, because the E320 is rated at a darn respectable 27 mpg city and a whopping 37 mpg highway. As a matter of fact, Mercedes says that the E320 sprints from 0-60 in 6.6 seconds, which is only one-tenth of a second behind the gasoline V-6-powered E350. There is no perceptible turbo lag, and during hard acceleration the engine generates the sound and pull of a small-block V-8. When it comes to power, the engine hauls the 3,835-pound sedan with authority. Diesel rattle is muted-more like nonexistent-throughout the engine's rpm range. It's clear that Mercedes engineers spent a considerable amount of time ensuring that the 3.2L CDI engine integrates seamlessly with the dignified E320. It would take 20 more pages to detail the scores (literally) of other high-tech devices that loom inside the E320, but we want to talk about the engine.ĭriving the E320 CDI is a lesson in refinement.

There are easy-to-understand, yet elegant dual-zone electronic climate controls, a nine-speaker Harmon/Kardon audio system with LOGIC7 surround sound, and a DVD navigation system. There is no shortage of technology in the E320 either.

We feasted our eyes on Burl Walnut trim, and the Stone interior color made the car feel open, airy, and inviting. As we slid into the creamy leather driver's seat, the door closed with little effort like the door latch was tenderly reaching out to grasp the catch. During our initial inspection, we were impressed by the impeccable fit and finish of the car, as well as the attention to small, but welcome, items (like covered trunk hinges) that make the trunk area flow visually when the trunk lid is open. To call this vehicle polished would be like saying that Mount Everest is a cute little hill. We recently spent some quality time with the '06 Mercedes-Benz E320 CDI.
