The time has never been more right for diesel cars to make a comeback in America. Greater efficiency and new government standards for cleaner diesel fuel have combined to make diesel a more enticing prospect for American car buyers.
Based on historical data from the EPA, between 2009 and today, the average price of a gallon of gasoline went from $2.65 in 2009 to $3.54 today. It’s causing Americans to rethink what powers the cars they drive. As a result, interest in diesel-powered cars has tripled, and is poised for even greater increases in the near future and manufacturers like Audi are answering that renewed interest with a range of products that offer not only efficiency, but the kind of performance Audi customers have come to expect.1
In Europe and elsewhere, diesel has always been a more attractive option on price alone. If you live in Norway, for example, you’d pay closer to $9.76 in U.S. dollars for a gallon of gasoline. Diesel is still expensive, but comparatively, it’s a bargain at about $8.69 per gallon.
The cost difference alone means that it’s the fuel of choice in Europe. But in the U.S., the prices of gasoline and diesel have typically been close, making it less appealing for American drivers to choose diesel over gasoline.
The future for diesel powered cars in the U.S. has never been brighter. When diesel first got a foothold here during the 1973 oil embargo, engine management technology was primitive at best. Today’s diesel engine technology is light-years ahead, featuring highly advanced engine management systems that monitor fuel intake and deliver fuel through direct piezo injectors that help provide improved fuel/air mixture to each cylinder.
The fuel itself is also cleaner than it was just a few short years ago. Since 2006, fuel companies have been required to produce ultra-low-sulfur diesel (ULSD), which has up to 97 percent less sulfur than before. ULSD was developed to allow advanced engine technologies that help reduce diesel emissions. With these technologies, Audi TDI® clean diesel models produce 12% lower CO2 emissions than those of a comparably-sized gas engine.1 Audi TDI® clean diesel models then capitalize on the cleaner fuel by using active exhaust gas after-treatment systems with AdBlue® reducing agents to change NOX emissions to nitrogen and oxygen. Then, advanced particulate filters remove and burn off the remaining soot. Total win.
And unlike the 1970s, when diesels were always last in performance, Audi TDI® clean diesel vehicles — including the A6 and A7 sedans, the Q5 crossover and Q7 SUVs, and the flagship A8 L — blend advanced diesel fuel management technology with turbocharging to deliver a truly exciting, amazingly efficient driving experience.
All around, Audi TDI® clean diesel technology is delivering everything that a performance-oriented yet eco-conscious driver wants from a modern automobile. The time is right for diesel. Now it’s time to experience it for yourself.
