5 Series and you are welcomed by a luxurious yet familiar ambiance. From the driver’s seat the cabin feels spacious, open and crisply styled. The light beige and black combo, the massive glass area and the large sunroof further adds to the airy feeling.
The Z4 sDrive30i sports a 255-horsepower, 3.0-liter inline-six; a 300-horsepower, twin-turbo version of that engine comes in the sDrive35i. And the difference between these two models, actually, goes far beyond their 45-hp difference in engine output. In short, the sDrive30i drives more like a classic roadster, while the sDrive35i is faster but is best enjoyed in a different way.
