Много се отплеснахме от темата, но виж два бързи цитата дето намерих в гоогле:

VW will be dumping its line of TDI diesels by 2007 and switching to a common-rail design for all of its oil-burners, with annual production of the new engines totaling over 2 million units. This announcement can probably be taken as evidence that mechanical diesel injection has reached its practical limits, despite the relatively high level of refinement that VW has achieved using the technology. Indeed, there will probably be a number of faithful TDI owners who see no reason to give up the system that has brought respectable power and refinement to passenger-car diesels.

Meanwhile, the five time 24 Hours of Le Mans winner Audi R8 race car was replaced by the Audi R10 in 2006, which is powered by a 650 hp (485 kW) and 1100 Nm (810 lb·ft) V12 TDI Common Rail diesel engine, mated to a 5-Speed gearbox, instead of the 6 used in the R8, to handle the extra torque produced.
