Audi Q7 3.0 TDI Clean Diesel

Audi has announced the launch of the Audi Q7 3.0 TDI Clean Diesel on the British market. The Audi Q7 3.0 TDI Clean Diesel is the first model equipped with this technology to enter the UK market. The Audi Q7 3.0 TDI Clean Diesel will be one of the highlights of the 2009 Frankfurt Auto Show being able to remove up to 90% of NOx (Nitrogen Oxide emissions) particles from the exhaust gases. The Audi Q7 3.0 TDI Clean Diesel already complies with proposed EU6 emissions limits that are not due to come into force in Europe until 2014.

The Audi Q7 3.0 TDI Clean price for the UK market will start at £40,060.

A BREATH OF FRESHER AIR FROM AUDI IN FRANKFURT

Audi is pioneering the introduction of the world's cleanest diesel technology to the UK in Q7 SUV models that help to rid the air of Nitrogen Oxide (NOx) emissions, regarded by many as being dramatically more harmful to humans than Carbon Dioxide (CO 2 ). Capable of removing up to 90 per cent of NOx particles from exhaust gases, this ultra-low emission technology will be a highlight at the 2009 Frankfurt Motor Show (September 17 to 27), where it will be showcased in the compact executive A4 Saloon.

The Q7 3.0 TDI Clean Diesel (from £40,060 OTR) is the first passenger car to be available in the UK with this advanced system, which has been designed to maximise engine efficiency and to optimise the after-treatment of exhaust gas. With its help, the 3.0-litre TDI engine powering the Q7, and showcased in the A4 in Frankfurt, already complies with proposed EU6 emissions limits that are not due to come into force in Europe until 2014.

‘NOx trap'
The core components of this ultra-low-emission system are a new common-rail injection system (which generates up to 2,000 bars of pressure), innovative pressure sensors in the combustion chamber and an especially high-performance exhaust recirculating system. Collectively these measures ensure a highly efficient and low-emission combustion process. In addition, an innovative DeNOX catalytic converter, or ‘NOx trap', integrated within the exhaust system reduces residual nitrogen oxides, while just upstream of it a pump injects an aqueous solution called AdBlue into the hot exhaust flow, where it decomposes into ammonia. The ammonia then has the effect of splitting the nitrogen oxides into the inert gas nitrogen and into water.

The use of clean diesel technology reduces the output of nitrogen oxide or NOx by up to 90 per cent. The suppression of NOx is widely regarded by experts as being as crucial to our wellbeing as the reduction of CO 2 because on contact with sunlight it can form photochemical smog, a form of air pollution which can cause damage to lung tissue and a reduction in lung function.

Audi Q7 breathes easier – The Audi Q7 SUV is already available in the UK with a TDI engine featuring the world's cleanest diesel technology reducing emissions of harmful nitrogen oxide by up to 90 per cent. At the 2009 Frankfurt Show Audi will exhibit an A4 Saloon benefiting from the same advanced technology.

The Audi brand exceeded the milestone 100,000 sales mark in the UK in 2007 and 2008. Globally, the brand exceeded 1 million deliveries for the first time in its history in 2008. With its programmes for both road and race cars the brand continues to maintain its upward trajectory. On the road it has extended its reach into important new segments with new models such as the A3 Cabriolet, the Q5, the TT RS and the R8 5.2 FSI quattro, and in the near future will break further new ground with the A1 compact hatchback, the Q3 compact SUV and the A5 Sportback five-door coupe. On the race circuit Audi Sport has contested the Le Mans 24-hour marathon eleven times since 1999, achieving a podium finish on all of these occasions and outright victory a total of 8 times.
