Matt Farah does this youtube series where he drives various random cars each day (everything from custom muscle cars to 800 hp 335s to brand new cars such as this). I kind of enjoy them. Anyway, I enjoyed this review because the owner seems to an enthusiast and knows a lot about the 340 (particularly the new engine). Kind of intrigued me- will atleast have to test drive on at some point. As always with BMWs, the subject of leasing came up and the owner alludes to getting an excellent deal. That's always what makes it hard to walk away from BMW. If I can pick up a loaded 60k one for around 500 all-in at some point I'll probably be tempted.
Some highlights of the new engine:
-closed deck design
-air to liquid intercooler
-forged crankshaft
-mechanical water pump
-dedicated electric coolant pump for turbo (can keep coolant flowing after engine shutdown)
Sounds like it has the makings of a pretty stout, durable engine. Interesting that they made so many changes from the n55
