== VVT-iW == [[File:2018 Toyota Crown 8AR-FTS.jpg|thumb|right|The 8AR-FTS engine, the first to feature VVT-iW]] '''VVT-iW''' (Variable Valve Timing - intelligent Wide) was introduced with the 2.0L [[turbocharged]] [[Fuel injection#Direct injection systems|direct-injected]] ''[[Toyota AR engine#8AR-FTS|8AR-FTS]]'' fitted to the [[Lexus NX 200t]]. VVT-iW uses VVT-iW on the intake valves and VVT-i on the exhaust valves. The intake cam has mid-position cam lock mechanism that retards the continuously variable timing. It offers expanded valve opening angles (Wide) which enables the engine to operate in a modified-[[Atkinson cycle]] at low rpm for improved economy and lower emissions and in the [[Otto cycle]] at high rpm for better performance, while also delivering high torque throughout the entire rpm band.<ref>{{cite web|url=http://www.greencarcongress.com/2014/09/20140905-camry.html |title=Camry in Europe features new 2.0L engine with VVT-iW.. |publisher=Green Car Congress |date=2014-09-05 |access-date=2016-06-27}}</ref> {{clear}}
