Audi is the pioneer in turbocharged diesel engines with direct injection - since 1989 the company has built and sold more than 4.5 million cars with TDITDISynonymous with muscular torque delivery and outstanding efficiency: TDI. Today, TDI engines are sporty, smooth and economical.TDI engines. From the very start, the initials TDI began to develop into a synonym for superior propulsive power and a maximum efficiency; the technology has advanced to become a trend setter for the entire automotive industry.
No other drive system has yet been able to beat the turbocharged diesel direct injection engine when it comes to power combined with low consumption. When driven by customers, consumption by TDI cars is up to 40 percent lower than comparable cars equipped with petrol engines.
The engine that Audi presented in late summer of 1989 at the Frankfurt motor show: The five cylinder turbodiesel, installed in the Audi 100, featured 2.5 liters of displacement for 120 hp and 261 Nm of torque. It was the world's first diesel passenger car with direct injection and fully electronic engine management - the first TDI. With its brawny power, the five cylinder engine, that went into regular production in what was then the fourth generation of new Audi 100s, set a new standard in the diesel sector. Since then, Audi has extended this technological advantage with continuous, new phases of development.
Half of All Audi Vehicles Feature TDI
For the past 19 years, the brand with the four rings has been using its accumulated innovative capabilities to repeatedly extend the limits of possibility. The TDI engines have had a decisive impact on the emergence of Audi as a maker of premium sports cars; today, half of all Audi vehicles that are sold around the world have a diesel engine under the bonnet. The TDI engines have achieved an unprecedented triumph - and are continuing on at full throttle.
In Europe, the success of the TDI principle has been unmatched - today, more than half of all new cars sold in Western Europe are equipped with a modern diesel engine, and in some countries the proportion of diesels has reached 80 percent. This makes the direct injection diesel engine the world's most successful efficiency technology.
