Audi has announced they will launch their new generation diesel engines starting in the second half of 2008 starting with the 3.0 liter V6 unit in the Audi A4 and Audi Q7. The optimized engine gets a small increase in horsepower from 233 bhp to 240 bhp while torque generously bumps up an additional 50 Nm from 450 Nm to 500 Nm and 500 Nm to 550 Nm respectively.
Due to the very low emissions which comply with BIN 5 requirements in the US (including California) as well as the upcoming new Euro 5 levels, the engines will be put into circulation worldwide. After the A4 and Q7 models, the engine will be gradually integrated into the remainder of the model range by 2010.
The innovations responsible for the reduction in emissions and increase in power are the new piezoelectric injection system, extremely efficient exhaust gas recirculation system (EGR) and optimized turbocharging. But the biggest innovation are sensors positioned in the engine which regulates the combustion process more precisely. Audi doesn't state more specifically where in the engine the sensors are located, but high levels of deductive reasoning leads one to believe it's inside the combustion chamber. According to Audi, this is a world first.
Audi also takes a moment to tell us about future developments for TDI and TFSI models such as a new brake energy regeneration system. It's a power management system which stores electrical power generated by the brakes when coasting or braking. In addition, a next-generation start-stop system is currently being developed as well.
Take these new technologies and add them to Audi's “e” (for extra-efficient) package which consists of reduced-friction tires, shift indicator, taller gear ratios, aluminum hood, and enhanced aerodynamics and fuel efficiency increases even more. Audi plans to offer the “e” package to all TDI and TFSI models except for lower volume cars such as the S3.
But the fun doesn't end there. Intended for use in several Audi models, plans for a “full” hybrid propulsion system, as seen in the Audi Q7 Hybrid Concept from 2005, which utilizes an electric motor positioned between the engine and transmission can run on either petrol engine or the electric motor alone or a combination of both. Using the brake regeneration system mentioned above, the electric motor's batteries are charged.
Audi states it will be the first manufacturer to meet future emission requirements.
PRESS RELEASE
Audi to launch the cleanest diesel in the world
For Audi, the trendsetting TDI engine is a core element of its integrated technology strategy. “We intend to consolidate the status of the TDI as a highly efficient form of propulsion on a sustained basis. And in future we will be launching ‘e’ model variants designed for optimised fuel consumption in the high-volume model series – either in TDI guise or as petrol models with state-of-the-art TFSI technology,” says Rupert Stadler, Chairman of the AUDI AG Board of Management.
