The BMW X3 M40i could be the perfect X3 for most people. Powering this compact premium SUV is one of my favourite engines, BMW's inline twin power turbo 6 cylinder. Although not quite as quick and extreme as the BMW X3M, it still packs over 380 horsepower, makes a run to 60 mph in just over 4 seconds and has perfect road manners making it ideal for everyday driving.
