The visionary designers at BMW took an X3, modified the tail end to give it a sportier look and called it the X4. And it worked! Under the hood, there's a 241-horsepower, 2.0-litre four-cylinder, but the 3.0-litre 355-horsepower six-cylinder (M40i) is recommended if you want to respect the model’s sporty nature. Just a heads-up: it costs an extra $12,000. Since it’s an SUV, all-wheel drive comes standard.
