Turbo Fours and IS F Considered, No Wagon

Lexus IS chief engineer, Junichi Furuyama , has confirmed that small capacity turbocharged four-cylinder engines are being considered for the new sedan, while a wagon variant has been rejected.

Speaking at the Detroit auto show, where the third-generation Lexus IS made its official debut, the chassis chief said that Lexus “still have some time to consider” whether the existing 2.5-litre naturally aspirated V6 would be replaced by a smaller, boosted engine.

“Turbocharged downsizing engine is something that we keep as one of the options,” added Furuyama-san.

“Currently we are considering whether or not we should maintain the current naturally aspirated V6 engine, or we should shift to turbocharged downsizing.”
