More Information

The term "Clean Diesel" refers to innovative diesel engine technology, as well as the latest diesel fuel for vehicles. In contrast to traditional diesel, Clean Diesel is superior, since both the new generation of engines and the fuel itself meet the strictest emission regulations in the U.S. (issued by the state of California). Clean Diesel fuel contains less than 15 parts per million of sulphur; our Clean Diesel partner vehicles deliver on average 18% higher fuel efficiency while reducing CO2 emissions when compared to corresponding gas models. Since Clean Diesel is not only cleaner but also more fuel-efficient, the new Clean Diesel vehicles are friendlier to both the environment and drivers' wallets throughout the U.S.

Our partner's Clean Diesel vehicles are on average 18% more efficient than corresponding gasoline models. This means that even if diesel fuel costs slightly more than gasoline in the U.S., Clean Diesel vehicles manage more miles per gallon.

Clean Diesel power trains have a great operating range. For example, with a full tank it might be possible for a VW Passat Clean Diesel or a Porsche Cayenne Clean Diesel to travel over 700 miles on the highway.1

Our Clean Diesel partner engines demonstrate on average 18% higher fuel efficiency in comparison with their modern gas engine counterparts thus facilitating significantly larger ranges. This implies that the diesel engine makes a higher contribution to the achievement of fuel-economy objectives, which in turn leads to significantly fewer trips by the customer to the gas station.

Trips to the Pump calculations

For Diesel, the multiplier is 0.46 x Number Of Miles Traveled Per Day = Annual Trips Per Year

For Gas, the multiplier is 0.71 x Number Of Miles Traveled Per Day = Annual Trips Per Year

Diesel


Diesel — One tank of clean diesel is based on the Volkswagen Passat TDI®. The Passat TDI® holds 18.5 gallons per tank, gets EPA-estimated 43 mpg on highways and therefore, under optimal conditions, may get 795 miles per tank on the highway.2
("z" miles per day X 365 days per year) / 795 gallons per tank (or trip) = 0.46z

Gas


One tank of gas is based on the Toyota Camry, which was the second-most-sold car in 2011 that was not a pickup truck.3 The Camry holds 17 gallons per tank, gets an EPA-estimated 28 mpg on highways and therefore, under optimal conditions, may get 476 miles per tank.4 In order to have a fair comparison, the Diesel and Gas vehicles must hold the same gallons per tank, so for calculating purposes 18.5 gallons per tank will be used. With this, a Camry might be able to get 518 miles per tank on the highway.
("n" miles per day X 365 days per year) / 518 gallons per tank (or trip) = 0.71n

My Wallet Calculations


Source of prices for Gas and Diesel by state: http://fuelgaugereport.opisnet.com/index.asp
This calculation will be based on the average number of annual miles driven per driver in the U.S. as of 2011, which is 13,476 miles.5 The gas vehicle used in the calculation is the Toyota Camry (EPA-estimated 28 mpg hwy) and the diesel vehicle is the Volkswagen Passat (EPA-estimated 43 mpg hwy).

Total Savings Formula = [Cost for Regular Gas X (13,476 miles per year / 28 MPG)] – [Cost for Diesel X (13,476 miles per year / 43 MPG)]

Performance Header

Whether premium passenger cars or premium SUVs/CUVs, a modern 6-cylinder Clean Diesel is as powerful as a V-8 gasoline model and as efficient as a 4-cylinder vehicle.6

The Diesel sounds were provided by Robert Bosch GmbH. The old sound is from a Diesel passenger car launched in 1990 and the new sound is from a Clean Diesel passenger car launched in 2011.

Environment header

In the summer of 2011, the U.S. Secretary of Transportation was already emphasizing that the U.S. could save about 1.4 million barrels of oil every day if one-third of all cars were fitted with Clean Diesel power trains.7

Clean Diesels have such low (classical) pollutant emissions that they meet the strict-limit values in all 50 federal states, including California (AdBlue and SCR).

Modern diesel power trains have been developed to reach the status of high-performance, more fuel-efficient, sophisticated and, above all, cleaner engines than their gasoline counterparts. As a result of the emissions legislation, exhaust emissions from diesel engines have been reduced by 96 to 98 percent since the start of the nineties.8

CO2 Calculations

If one-third of all Americans switched to Diesel vehicles, about 1.4 million barrels of oil would be saved. From each barrel, 19 gallons of motor gas is created.9 From each gallon of gas, 20 pounds of CO2 are emitted.10 That means saving about 1.4 million barrels of oil is equivalent to about 532 million pounds of CO2 that would not be emitted from motor gas. Since trees absorb CO2, it would require the planting of about 600,000 trees each day to absorb the extra 532 million pounds of CO2 emitted by gasoline-powered engines.11

In 2009 (Volkswagen's Jetta TDI®) and 2010 (Audi's A3 TDI®) Clean Diesel models won the renowned "Green Car of the Year" award (the BMW 335d, the Volkswagen Golf TDI® and the Volkswagen Passat TDI® were among the top five finalists).

Sales of clean diesel passenger cars rose by 36 percent in 2011.
