Here's our answer. BMW has the next version of the N55 set for release in the 640i Gran Coupe.

Thread

Excerpt:

Thanks to intensive fine-tuning of the engine, BMW's engineers have managed to extract additional performance from the engine while maintaining its exceptional fuel efficiency. With a maximum power rating of 225 kW/315 hp at 5,800 to 6,000 rpm, the 3.0-liter 6-cylinder engine reflects the sporty personality of the BMW 640i Gran Coupe and helps this automobile deliver brilliant performance. The high peak torque of 330 lb-ft, on stream between 1,300 and 4,500 rpm, ensures that the power is effortlessly and instantly delivered.

Looks like a 315HP/330lb-ft N55. Not a huge difference on paper, but BMW does tend to underrate these engine's power. BMW says it will get the 640 to 60 MPH in 5.4 seconds. I imagine the 335 will be as much as a half second quicker on weight advantages. The Gran Coupe is a huge car...
