Say goodbye to the seventh-generation BMW 5 Series and say hallo to the all-new eighth-generation codenamed the G60. Available in 520i, the next-generation 5 Series gets a bolder look along with a more high-tech (and more luxurious cabin). And just like the all-new 7 Series, the 5 Series is now powered by a 48V mild-hybrid turbocharged engine that delivers more pep while also lessening carbon emissions.
