A 4,800 mile real-world test track is showcasing the capabilities, fuel efficiency and low-emissions system of the 2009 Audi clean diesel Q7 3.0 TDI. As more than 184 drivers travel across the country in the new vehicles, they will experience the Good, Clean, Fun of the diesel common rail system and other components supplied by Robert Bosch LLC, according to the manufacturer.
The Audi Mileage Marathon began in New York and concluded in Los Angeles Oct. 20. Drivers representing countries in North America, Europe and Asia drove the fuel-efficient vehicles in 13 daily stages.
Bosch was selected by Audi to supply the common rail system that includes the electronic control unit (ECU), rail, pump and injectors, the dosing module and control unit for the Denoxtronic system, as well as various sensors for powertrain and exhaust gas aftertreatment in the Q7 3.0 TDI. The Denoxtronic reduction-agent metering system from Bosch permits further reductions in the emissions of diesel engines. It is a central component of the SCR system (Selective Catalytic Reduction).
"The Audi Mileage Marathon provides opportunity for people to experience torque, fuel economy and other benefits of today's clean diesel technology in action," says Bernd Boisten, regional president, diesel systems North America, Robert Bosch LLC. "We call today's diesel Good, Clean, Fun. We wish all participants safe journeys and look forward to their reactions to clean diesel's fuel efficiency, low emissions and exceptional performance."
Clean diesel technology combines clean diesel fuel, advanced engines and effective exhaust control technology into a complete package that is more efficient, environmentally friendly and fun to drive. Today, a clean diesel engine is one of the "greenest" powertrain options on the market, Bosch adds, stating diesel provides 30 percent better fuel economy than a comparable gasoline engine, translating into more miles per gallon and fewer trips to the pump. At today's prices, this fuel economy advantage more than offsets the price differential between gas and diesel fuels.
