Last two vehicles were '15 Porsche Macan S (delivered on launch day), and '19 BMW X5, both excellent, but a bit shy in the fun quotient. Now this new M340i...back to looking forward to driving....somewhere, anywhere. Haven't had this much driving enjoyment since my '99 E36 M3. This car does everything well. Both powerful and efficient. Solid (rigid) construction, quiet, and handles better than the Macan. 90 mph feels like 60. This B58 inline six mated to the ZF 8 transmission is incredible....every bit equal (imo) to the Porsche PDK. No more SUV's for me...long live the Sport Sedan. If you want ride a little softer, and don't need the 382 hp, the 330i is a great choice. Just don't test drive the M340...it'll cost you some $$. 14K mile update: Still impressed by the performance and efficiency....25.2 mpg since new. Gets 37 on trips. Still rock solid and trouble-free.

I special ordered my 2021 M340i xDrive from the Munich plant and received it mid-July. Just finished the 1200 mile break-in and am now thoroughly enjoying its considerable performance. The engine is the best I have owned in 45 years of driving. It is strong, smooth and very fuel efficient. It gets around 34 mpg in real world highway driving and over 28 mpg around town! Acceleration is effortless. I ordered it with the standard M suspension and it has a very good ride/handling balance. The car is very comfortable and quiet when you want it to be. If you want a louder exhaust note the pressing of the sport button will take care of it for you. Love the technology and looks of the car. I also owned a 2019 BMW 330i xDrive, but I prefer the M340 because of its 6 cylinder engine. Can’t go wrong with this car!
