It’s no secret the new Toyota Supra is powered by a BMW-sourced inline six-cylinder engine. But now a fresh report out of Japan suggests the next-generation Lexus IS sedan will also inherit the Bavarian brand’s B58 unit.

According to Best Car, the upcoming fourth-generation IS sedan will be offered with a version of BMW’s turbocharged 3,0-litre straight-six, which also powers the new Z4 roadster and M340i sedan. The report furthermore suggests Toyota’s luxury arm will also offer 2,0- and 2,4-litre engines lower in the IS range, along with a 2,5-litre hybrid powertrain option.

And what about the flagship IS F? Well, Best Car claims the high-performance variant will draw its urge from a version of the turbocharged 3,5-litre V6 already used in the LS saloon, where it makes 310 kW and 600 N.m.

The Japanese publication furthermore says that while the next-generation IS will be around the same size as the current model, it will lose as much as 150 kg.

Expect Lexus to whip the covers off the new model at some point towards the end of 2020.
