Despite focusing on hybrid technology to achieve most of its efficiency gains, Lexus will now follow rival automakers in the luxury segment by offering downsized turbocharged four-cylinder engines in the coming years.

We’ve previously reported that Lexus would offer a turbocharged 2.0-liter four-cylinder engine in its upcoming compact crossover, the ‘NX,’ and now Automotive News (subscription required) has revealed that the engine will be available by late next year or early 2015.

A previous filing made by Toyota with the U.S. Patent and Trademark Office revealed the “NX 200t” and “NX 300h” names, with the former expected to be used for the NX crossover equipped with the turbo four.

The NX 300h will feature a hybrid drivetrain consisting of a 2.5-liter four-cylinder engine matched with an electric motor. A version of this drivetrain is already offered in the ES 300h as well as an IS 300h sold overseas.

A concept version of the NX compact crossover is expected to be revealed at the 2013 Tokyo Motor Show at the end of the year. A production version will likely arrive in the fall of 2014, making it a 2015 model.

Beyond the NX, the new turbo four may make its way into the IS as a replacement for the IS 250 model’s aging 2.5-liter V-6, which delivers just 200 horsepower.
