Auto manufacturers — including Audi — are constantly exploring alternative ways to power their automobiles. Recent advancements in lithium-ion battery technology have allowed hybrid and full-electric cars to drive further on electric power alone, and hydrogen fuel-cell vehicles are in development as well. But today and for the foreseeable future, diesel offers a practically unbeatable combination of efficiency, lower emissions, and performance.1

The fuel economy portfolio
Audi is working to eventually develop a complete fleet of CO2-neutral vehicles for sale around the world. And Audi isn’t focused on one or two technologies to power its cars into the future. It offers — and has in development — a portfolio of technologies to consider when you purchase your next car. Today, Audi offers a suite of vehicles powered by gasoline, diesel, and hybrid technologies which combine gas and electricity. TDI® clean diesel is a crucial part of the formula that allows Audi to continuously help improve fuel economy without sacrificing the performance Audi drivers have come to expect.

With an increasing array of TDI® clean diesel powered models, Audi delivers greater fuel efficiency — when compared to similarly sized gasoline engines without direct injection — while maintaining an exciting driving experience and a readily available refueling infrastructure already in place. Diesel fuel unlocks amazing efficiency potential by delivering 15 percent more energy per drop than gasoline. That energy potential translates to 30 percent better fuel economy for TDI® clean diesel engines; and on the road, you can reduce your fuel stops by 20 percent over the gasoline counterpart.2

A younger audience
What’s worked against diesel in America is actually beginning to work in its favor on a number of fronts: diesel power in the 1970s. The drivers of that era who experienced long lines at the gas pumps and sooty diesel-powered cars now represent an older demographic. Early adopters have understood diesel’s appeal for years, watching half of Europe’s automotive fleet provide outstanding efficiency and diesel-powered fun. Now many more American drivers are poised to accept TDI® clean diesel power because they understand the advantages it offers.|

A growing infrastructure
One of diesel fuel’s great advantages is that it’s becoming more widely available. Currently, about 52 percent of all filling stations across the United States offer diesel fuel along with gasoline, and that availability is on the rise, especially as filling stations begin to refit and renovate. Diesel availability has been increasing since the late 1990s.

Facts like this have translated into a renewed interest in diesel-powered vehicles. In 2012, diesel market share — the percent of diesel-powered cars in the marketplace — increased by 13.4 percent. Audi alone increased its TDI® clean diesel offerings by 5 percent in the 2013 calendar year.

Since 2006, when Audi first won the 24 Hours of Le Mans with the Audi R10 TDI®, Audi been a leader in diesel performance and technology. Now it’s time for America to experience the kind of performance, efficiency, convenience that the rest of the world has been enjoying for decades.
