Behold the 335i replacement, the all-new 340i. With it BMW has introduced the brand-new #B58 engine, 6 cylinder, at the core of the 340i's power. Based on its #N55 twin-scroll turbocharged predecessor, the B58 boasts a turbine 6% larger in size than that of the outgoing 335i combined with a compressor wheel diameter that is 10% larger, resulting in a 20% increase in total boost pressure. This results in the 340i making power figures of up to 320 hp (239 kW). We can safely assume that this figure is underrated on the basis of the outgoing 335i's also heavily underrated numbers.

This 340i was found on the following thread:
