About BMW M5
The BMW 5 Series has long been the benchmark for midsize luxury sports sedans. It maintains the performance cred earned over the decades, yet now offers so much more. The 2015 BMW 5 Series is available in a dizzying variety of versions, from a $50,000 base model with a 4-cylinder engine to the fire-breathing M5 costing nearly twice that much. In between are diesel and hybrid variants, and even the Gran Turismo 5-door hatchback, whose SUV-like practicality somewhat alleviates its awkward looks. As the 5 Series lineup has expanded, so has a list of rivals that includes the Mercedes-Benz E-Class, Audi A6 and Lexus GS. Amid the stiff competition, the 5 Series remains a standout with its blend of performance, technology and brand cachet.
