context_page_description: The AR engine family is an Inline-4 piston engine series by Toyota, first introduced in 2008 for the RAV4, and subsequently for the Highlander, Venza, Camry and Scion tC.
  The AR series uses a die-cast aluminium engine block and aluminium DOHC cylinder head. The engine series shares many of the technologies in the AZ engine, while incorporating new features such as variable valve timing on both intake and exhaust camshafts or dual VVT-i, low friction technologies including an offset crankshaft, roller rockers for the valvetrain, a three-stage variable oil pump, reduced-tension piston rings and auxiliary belt drive. An Acoustic Control Induction System switches the length of the intake tract in two stages, based on rpm and throttle angle, thereby ensuring strong torque across a broad engine speed range. New tumble control valves enhances combustion while the engine is cold, and helps to bring the catalytic converters up to working temperature quickly. The Tumble control valves, along with new 12-hole high atomizing long-nozzle fuel injectors, reduce the amount of fuel adhering to the intake ports and therefore maximize fuel economy and reduce harmful emissions.
context_section_description: A 2.0 L turbocharged direct-injected member of the AR family, fitted with VVT-iW it is able to operate in both the Otto and a modified-Atkinson cycle. Debuted in the Lexus NX200t. Power output in the 2015 NX200t is 175 kW (235 hp) at 4,800 - 5,600 rpm and 350 N⋅m (258 lb⋅ft) at 1,650 - 4000 rpm.  The 8AR-FTS engine has Lexus’ ESTEC D-4ST (Economy with Superior Thermal Efficient Combustion Direct injection 4-stroke with Turbo) fuel injection.  With separate twin injectors for both direct and port injection, ESTEC D-4ST could perform high-pressure direct injection into the cylinder and conventional intake port injection, or direct cylinder injection only, according to engine speed.  Power output in some applications, e.g. Lexus IS 200t XE30, Lexus GS 200t and Lexus RC 200t is bumped up by 5 kW (6.7 hp) up to 180 kW (242 hp) in the same rev range but torque remains the same.
  Applications:
  Lexus NX 200t (renamed NX 300) AGZ10/15
  Lexus IS 200t (renamed IS 300) XE30
  Lexus GS 200t (renamed GS 300) L10
  Lexus RX 200t (renamed RX 300) AL20
  Toyota Crown
  Lexus RC 200t (renamed RC 300)
  Toyota Highlander (XU50, China)
  Toyota Harrier Turbo (XU60, Japan, 2017–)
