The 2017 BMW X4 xDrive28i has a 2.0-liter turbocharged four-cylinder engine that produces 240 horsepower and 260 pound-feet of torque. All-wheel drive, an eight-speed automatic transmission and an automatic stop/start system are standard. At the Edmunds test track, an X4 xDrive28i sprinted to 60 mph in 6.3 seconds, which makes it the quickest in the segment for a base engine (at the time of this writing). We expect EPA-estimated fuel economy to stand at 23 mpg combined (20 mpg city/28 mpg highway) for 2017.

The M40i has a 3.0-liter turbocharged inline-6 good for 360 hp and 343 lb-ft of torque. It, too, has all-wheel drive and an eight-speed automatic. BMW says that it will hit 60 mph in 4.7 seconds, which would best (by quite a lot) all in the segment except the Porsche Macan Turbo. EPA-estimated fuel economy is 21 mpg combined (19 mpg city/26 mpg highway), which is pretty remarkable given its performance.
