Among the world's first compact luxury SUVs, the BMW X3 remains a leader in its category. There are two available engines for 2017: a 241-horsepower, 2.0-litre four-cylinder (xDrive28i) or a 300-horsepower in-line six (xDrive35i). The diesel engine should be available later this year. The X3 is not the only one out there: it will now rub elbows with the Audi Q5 and Mercedes-Benz GLC, among others.
