Audi Mileage Marathon Rules
The Audi Mileage Marathon involves 23 TDI powered vehicles, more than 150 competing journalists, and a distance 4,800 miles (7,700 kilometers) across the continental United States.
To ensure a level playing field for all participants in this first of a kind challenge, Audi called on the International Motor Sports Association (IMSA) to supervise and sanction the entire competition. IMSA is a highly respected organization that also oversees the American Le Mans Series.
For the two-week Audi Mileage Marathon, journalists are paired in teams of two to a vehicle. At the end of every day’s driving, each of the 23 competing vehicles will be accurately measured on distance, speed and most importantly – fuel consumption. The fuel tanks are refilled and sealed each evening.
IMSA will determine the most fuel efficient driving team.

Mileage Marathon – Confirmation of Excellent Efficiency
Ingolstadt/Denver , Oct 14, 2008 – As the Audi Mileage Marathon progresses, TDI technology continues to demonstrate its exceptionally efficient use of fuel. With more than half of the 8,000-kilometer (4,971-mile) route now completed, 90 drivers from twelve countries have already driven the 23-vehicle fleet. The best economy figures for the Audi Q5 are particularly impressive: despite the long distances and high average speeds, this model with its 3.0-liter TDI engine has recorded a fuel consumption of only 6.2 to 6.5 liters per 100 kilometers (37.94 to 36.19 US mpg) on most of the stages.

What about the cost of diesel fuel? With the pump price about eighty cents more you would have to show me a huge mpg difference to justify the price
Tess said
well the avg. mpg is pretty high and if the price of diesel fuel would go down america could see a big change! The more people who used diesel the more that high price would drop.
Chris said
The cost of deiesel is higher. But isn’t the reliability of diesel engines higher than gasoline engines. Ive seen family diesel engine cars last between three and four hundred thousand miles. Id bet that overall owning one of these new cars would save you money in the long haul.
Bruce said
Is the whole idea of hybrids in violation of Biblical principals? Deu 22:11 Do not wear clothes of wool and linen woven together. Meaning that the combining of two energys like electricity and internal combustion would make the energy unreliable such as if you weave wool and linen together.
I don’t know, just asking?

Mileage Marathon: Perfection in Efficiency
INGOLSTADT/LAS VEGAS , Oct 17, 2008 – The Audi Mileage Marathon is now into its third, decisive stage: when the fleet of 23 vehicles reaches Las Vegas, it will have completed about three-quarters of the total distance. In each successive stage, these cars from four Audi model lines have confirmed their exceptional fuel economy. The excellent results from the Audi A4 3.0 TDI quattro set a fine example: although its V6 TDI engine performs so well, its fuel consumption has been as low as 5.3 liters per 100 kilometers (44.38 US mpg) on many sections of the route.

Diesel – Good, Clean, Fun
Clean diesel technology combines clean diesel fuel, advanced engines and effective exhaust-control technology into a complete package that is more fuel efficient, environmentally friendly and more fun to drive. We call this triple-punch, diesel-advantage good, clean, fun:
Fuel: Refiners have lowered the sulfur content in diesel fuel by 97 percent from previous blends, cutting emissions by 10 percent and, when combined with new engines and exhaust treatment, reduces emissions by more than 95 percent.
Engine: Advanced technologies – electronic controls, common rail fuel injection, variable injection timing, improved combustion chamber and turbocharging – make today’s diesel engines cleaner, quieter and more powerful.
Exhaust Control: Traps that collect fine particles and catalytic converters that reduce ozone-forming compounds and particles, further lower engine emissions.
Good
• Clean diesel-powered vehicles average 30 percent better fuel ecnonomy than gasoline-powered equivalents.
• Better fuel economy means fewer trips to the pump.
• Clean-diesel passenger vehicles are being introduced in 2008 that meet emission standards in all 50 states. Initially, they are being introduced by Audi, BMW, Mercedes-Benz and Volkswagen. Joining them shortly will be Acura, Chrysler, Ford, Honda, Hyundai, General Motors, Mitsubishi, and Nissan.
Clean
• Clean diesel engines reduce greenhouse gas emissions by up to 20 percent.
• The EPA estimates that if one-third of U.S. passenger cars, pickup trucks and SUVs ran on diesel, the U.S. could save as much as 1.4 million barrels of oil per day. That is equivalent to nearly 12 percent of our oil imports.
• Today’s diesel engines are clean with minimal impact on overall air quality issues by having only:
o Two percent of carbon-monoxide emissions.
o Less than three percent of hydrocarbons.
o Three percent of sulfur dioxides.
o Four percent of particulate matter.
Fun
• Diesel cars are more powerful than their gasoline equivalents.
• Diesel engines offer, on average, a 50 percent increase in torque, an element of power, allowing diesel-powered cars to accelerate faster, especially on highways and hills, and to pull more weight.
• Diesel racecars, such as the Audi R10 and Volkswagen Jetta, participate in racing events around the world including Le Mans and Jetta TDI Cup.

Bosch Diesel Technology
What aspects of a diesel engine does Bosch make?
Bosch is a worldwide leader in powertrain development, and has been advancing the state of diesel engines for more than 75 years. Bosch diesel technologies include:
• Common rail injection systems – This type of system uses a high pressure pump, injectors and an electronic control unit to provide increased fuel economy and reduced noise and emissions. Bosch’s latest generation of common rail systems, with piezo-inline injectors that deliver pressure of up to 2,000 bar, continue to reduce emissions, engine-specific fuel consumption and combustion noise.
• Piezo-inline Injectors – The special feature of the third-generation common rail is the inline injectors with their piezo actuators integrated into the injector shaft located near the nozzle needle. The inline injector transmits the movement of the piezo package without mechanical elements and friction to the nozzle needle, which allows for extremely quick switching. Additionally, the system provides OEMs with more freedom in engine design.
• Electronic diesel control (EDC) – With the advent of EDC it became possible to implement more innovative functions. These allow the diesel engine-equipped vehicle to satisfy customer demands for comfort and convenience, dynamic performance, fuel economy, and low emissions. In addition, the EDC permits on-board diagnostics and communication with other EDC’s in the vehicle. Basic design of the EDC is the same for both, passenger cars and commercial vehicles, but the construction various by the application. Supplementary functions can be integrated either as hardware or as software.
• Exhaust gas sensors – This is usable in diesel and gasoline exhaust-gas management. With future engine conceptions, the space available for exhaust-gas sensors will be getting ever tighter. In addition, the sensors will be subjected to ever higher temperatures. Smaller, lighter, more versatile and above all ready for operation in the shortest possible time: these will be the outstanding advantages of our further developments. In order to conform to the future more stringent exhaust-gas regulations, high-quality materials will be required which can withstand higher temperatures also at those points where connections are made.
• Engine and exhaust gas management systems – Engine management uses an electronic control unit. The ECU controls all combustion engine functions: fuel mixture, ignition timing and exhaust gas composition. To optimize the system operation, the ECU utilizes: a variety of sensor torque calculation, numerous closed loop feedback systems, output actuator controls and self diagnostic operation.
Exhaust management uses a lambda oxygen sensor and lambda closed-loop control allow the most effective exhaust-gas purification via the three-way catalytic converter. During the critical warm-up phase, emissions can be reduced to a level at which Super Ultra Low Emission Vehicle and EURO IV regulations are met. With a broad measuring range, the broadband lambda sensor is appropriate for spark-ignition engines with intake-manifold injection and direct injection. In diesel engines, the sensor can reduce emissions by up to 20 percent. Additionally, it can determine the full-load limit by determining the maximum amount of fuel which can be injected at without exceeding a certain emission value.
• Exhaust gas aftertreatment devices for particulate matter and nitrous oxides – Aftertreatment technology that enable diesel vehicles to meet stringent emissions standards took effect in 2007. Bosch’s aftertreament products will include particulate filters as well as dosing units and control concepts for selective catalytic reduction systems.
