The new engine, originally designed with Ford and built in Mexico, offers substantially better fuel economy and lower CO2 emissions compared to the previous 3.6 litre V8 unit, but the engine is still not clean enough to strict U.S emission regulations. The current U.S emission laws are equivalent to Euro6 standards, which come into power in 2014. The 4.4 TDV8 is engineered to meet Euro5 standards.
Although, the next-generation version of the TDV8 engine is set to be launched in 2014/15, and Range Rover sources said the engine is “very likely to come to the U.S then”.
