Flagship sedans are an important part of any luxury automaker. For BMW, the latest 7-series offers buyers more of everything they could possibly want in the tech department, combined with a immensely spacious back seat and one of the quietest cabins in the business. For 2018, the new plug-in hybrid 740e offers buyers up to 14 miles of pure electric only range and 0-60 in 5.1 seconds. It could be the luxury car for drivers with an incredibly short commute, just be sure stand out looks aren't part of your importance as the current 7-series has a tendency to blend into the crowd.
