Audi celebrates 25 years of TDI

July 16, 2014

It’s incredible to know that since 25 years ago, Audi company have unveiled its first TDI engine, which become popular in both road and racetrack. Since 1989, Audi have sold around 7.5 million Audi TDI models.

As diesel cars generates low CO2 emissions comparatively petrol. So Audi have started to produce Diesel cars and with the present-day TDI clean diesel, Audi has reduced pollutant emissions by 98 percent over the past 25 years. Over the same period, the diesel engine’s power and torque have doubled relative to its displacement. Since 2000 alone, Audi has cut the average fuel consumption of the TDI fleet by around one-third.

Two latest innovative development of efficiency includes –

  • fuel-efficient 3.0 V6 TDI generation and
  • the Audi RS 5 TDI concept with electric charging.

3.0 TDI

The new generation of 3.0 RDI engine become one the best seller in the large Audi model lines and It will be making in the updated A7 Sport back*, which will go on sale in its first markets this fall.

With an increased output of 200 kW (272 hp), the new 3.0 TDI is even cleaner and achieves in the A7 Sport back 13 percent better fuel efficiency than its predecessor.

TDI clean diesel equally plays a key role in the Audi ultra models which is the most efficient and successful engine version in every model line.


With the electric biturbo, the brand with the four rings is giving diesel technology even more emotional and dynamic appeal.

The Audi RS 5 TDI concept – marks the first time that a diesel engine has powered a high-performance RS model with combination of V6 TDI biturbo with an additional electric-powered turbocharger, the RS 5 TDI concept achieves an output of 283 kW (385 hp) and up to 750 Nm (553.2 lb-ft) of torque.

The electric turbocharger develops its power especially quickly and smoothly even at low revs.

More Popular in European Countries –

With its fuel efficiency, supreme torque and superior economy especially for drivers who cover large distances, the TDI is popular in private customers and company car users as well.

Today, this diesel technology is especially popular among Audi customers in Western Europe are Germany, the United Kingdom and Italy are the biggest markets globally for TDI models. They are now expanding their business in Asia and North America.

Audi is pursuing the development of alternative fuels innovative technology. With U.S. firm Joule, Audi company has collaborated taking a fundamentally new approach to the diesel fuel of the future. They are working on producing synthetic fuels such as Audi e-diesel with the help of special microorganisms. Audi e-diesel is virtually climate-neutral, as it only releases as much CO2 during combustion as was bound during production.

Prof. Dr. Ulrich Hackenberg, Member of the Board of Management of AUDI AG for Technical Development says – “25 years of TDI mean a quarter-century of impressive technological progress. We look back on this time with pride, for the TDI has made a big contribution to our brand’s upward positioning in the premium segment. Today we are taking the next big step as we begin with its electrification.”
