500+ horsepower rumors for "M" 550dx diesel were wrong - Gets 381 horsepower, 516 lb-ft of torque
In an earlier article we reported that the 550dx was rumored to get 500+ horsepower
. We were skeptical and stated that previous 400 horsepower and 550 pound-foot of torque numbers sounded far more realistic. Well, turns out that is exactly the case as the final numbers are 381 horsepower and 516 pound-feet of torque for the triple turbo diesel powerplant. Disappointing? Yes, as the hype for this car was out of control. This motor is mated to all wheel drive as previously reported which will help put all that torque down. Expect to see this engine make its way into other BMW models like the X-series shortly.
