BMW 540i with 403 HP – Praise the B58 inline 6!

2y ago

Last week we had the BMW 530i and this week we are testing his big brother, the BMW 540i. It has the latest version of the B58 3.0 liter turbocharged I6 engine and in stock it already produces 340 HP.

With our RaceChip Chiptuning performance increasement we managed to gain incredible 403 HP out of the turbocharged straight-six engine.
