X5 gets 300 hp / 442 lb-ft Diesel - X5 40d - N57 engine
BMW has revealed that the X5 will get the N57 diesel which features the N57 diesel engine (306 hp, 442 lb-ft of torque) that debuted in the 740d. This motor features TwinPower Turbo Technology which is BMW's fancy way of saying a smaller turbo cuts in off idle and a big turbo take over up top.
You might be thinking, doesn't the X5 already have a diesel? Yes, it does, but in the United States the X35d has the older M57TU2D30 motor with 265 horsepower and 425 pound-feet of torque. The new diesel is also mated to an 8 speed ZF automatic transmission vs. the 6 speed in the X35D.
So will we see this motor in the United States? Currently 1 out of 3 X5's is sold as a diesel which is huge. The diesel market is taking off so BMW is paying attention to it. The United States does have extremely stringent diesel emissions rules however. Personally, I would really, really like to see this motor in the upcoming X3. I'll take any diesel in the X3 though, but the new N57 would be icing on the cake. Not to mention something very fun to tune
