This heightened metabolism also required an expanded renal system (enlarged bladder and kidneys) to remove large amounts of toxic urea, possibly resulting in a wide Neanderthal pelvis.

ATP (energy molecules) are used to convert amino acids to glucose, and even more are then required to convert the harmful protein byproduct ammonia into urea which is flushed away by the kidneys.

The diesel model requires an additional reservoir tank for the AdBlue, the urea cleansing agent added to further reduce nitrogen dioxide emissions.

To get to very low NOx, the lower pressure system essentially delays the moment of recirculation back to the turbo and an intercooler, and as a result, there's less NOx and Land Rover says that will result in lower required intervals to refill the DEF / AdBlue urea fluid.

That goes for the diesel, too: it uses urea injection, which requires a small reservoir to be refilled periodically in order to keep the engine running at its cleanest.

Note also, however, that the Passat Alltrack does require an aqueous urea solution, such as AdBlue, to be added at regular intervals.

The 350 uses a urea - based exhaust - treatment system that requires periodic maintenance.

The Bluetec SCR system requires a separate urea (AdBlue) tank to hold the exhaust additive.

Remember, Honda's plasma reactor converter makes it much easier to remove high levels of NOx gases from the exhaust stream, and unlike the Diamler BlueTec system it doesn't require lugging around a tank of urea fluid to inject urea gas into the exhaust stream to reduce NOx.
