The upcoming 2015 Lexus NX200t is equipped with the first turbocharged engine within the whole Lexus history. This engine has the Toyota internal code name “8AR-FTS”.

The 8AR-FTS has an 2.0L displacement with an open-deck, midi-skirt type aluminum cylinder block. It also has a fully balanced forged steel crankshaft, cast-in iron cylinder liners.

We get the latest news for the BMW F3x models. Starting from the 2016 model year, the current N20 4-cylinder turbo engine will be replaced by the newly designed B48 engine; and the award-wining N55 turbo-6, will be upgraded to the B58 engine.
