The BMW 528i gets up to 18/28 mpg city/highway, which is a bit above-average for the class. Opting for all-wheel drive or a more powerful engine will result in slightly lower estimates. While the 5-Series is fun on a winding road, reviewers also noted that its suspension is still comfortable and composed over road imperfections.They raved about the 5-Series' comfortable front seats and spacious back seat. Reviewers are generally impressed with the interior, exterior and performance and it offers minimal fuel consumption, hence it's cost effective. Owning this vehicle should find its way on every driver's bucket list. This car is a winner.
