Audiʼs entrant for this yearʼs Michelin Challenge Bibendum in Shanghai wasnʼt just some outlandish concept that will never see the light of day but a near production model equipped with features arriving soon in showrooms. Some of the enviro-friendly technologies Audi demonstrated include brake-energy recovery devices, engine stop-start mechanisms and the liquid AdBlue exhaust filtering system.

As impressive as it sounds, all of these technologies have already been used in production models by rivals BMW and Mercedes-Benz. The first Audi models to feature just the liquid AdBlue exhaust filter alone will be the A4 sedan and Q7 SUV 3.0L TDI models but these wonʼt arrive until early next year.

The 3.0L clean diesel has up to 90% less particulates in its exhaust than current TDI models and will allow the engine to meet new emissions standards in Europe due in 2014 as well as Californiaʼs strict LEV II BIN-5 standard. The engine also uses up to 35% less fuel than a comparable petrol engine.
