Lexus’ newly developed 2.0-litre turbocharged four-cylinder engine made its first debut under the bonnet of the new NX compact SUV last week.
While it’s been known the Lexus IS would be the next model in the brand’s lineup to receive the new turbo-four in the form of the IS 200t, Lexus has also reportedly given the go ahead for the engine to be used in the GS 200t and RC 200t. Both nameplates have been registered as trademarks in Australia, apparently. The turbo-powered models will be available by September 2015.
The Lexus CT has been spared, however, remaining only as a hybrid.
The new 2.0-litre direct-injection turbocharged engine in the NX produces 175 kW and 340 Nm. It features the world’s first combination of a cylinder head with an integrated water-cooled exhaust manifold and a twin scroll turbo charger. This combination in addition to other new technologies such as a turbo-specific D-4ST fuel injection technology and continuous variable valve timing with expanded valve opening angles (VVT-iW) ensures excellent driveability and fuel efficiency, claimed Lexus.
An all-new six-speed automatic transmission has been specifically developed to match the new turbo engine. It uses newly-developed control logic to calculate required engine torque. The resulting maximised engine torque gives responsive and smooth acceleration for higher efficiency.
