DSC_0576While diesels are available in every size and shape in Europe, where they account for an estimated 50% of cars on the road, they are still somewhat of a novelty in the United States. Therefore it is most unusual to have a market where three top competitors all offer an oilburner in one category.

Audi, BMW, and Mercedes-Benz each offer a diesel in the highly-competitive mid-sized luxury sedan market, with the Audi A6 TDI, BMW 535d, and Mercedes-Benz E250 BlueTec. The BMW and Benz are new for the 2014 model year, while the Audi has been on sale in the States for a while.

We currently have two of these fine motorcars in our long-term fleet, the Bimmer and the Benz, and recently spent over a week with the Audi A6 in a slightly more powerful European version, putting us in a position to take a good look at the strengths and weaknesses of all three.

The three cars are close to the same length at 193.1” (4904 mm) for the Bimmer, 193” (4902 mm) for the Audi, and 192” (4877 mm) for the Benz. The Audi and BMW are somewhat evenly matched in horsepower and torque, while the Mercedes has less power but better fuel economy.

The three make for a natural comparison so we felt it was time to ask Who’s King of the Diesel Luxury Sedan Hill?
