BMW 550 models have largely been situated as the top-tier trims offered on the 5 Series sedan. From 2011-2016, the 550i was the highest trim offered. After a brief hiatus for the 2017 model year, the 550i was rebranded as the M550i for the 2018 model year, offering standard all-wheel drive.
550i (2011-2016)
From 2011 through 2013, the 550i trim was outfitted with a turbocharged 4.4L V8 at 400 hp and rear-wheel drive (although BMW's xDrive all-wheel drive system was optional). A six-speed manual transmission was also standard, though an eight-speed automatic was available.
From 2014-2016, the 550i's turbocharged 4.4L V8 engine saw an increased hp output at 443-445 hp (depending on model year). The eight-speed automatic transmission that was optional in previous model years also became standard equipment in 2014.
