The current generation BMW 5-Series made its debut in 2011 and the current US line-up includes the 528i, the 535i, and the 550i models. After just two years, BMW has announced important changes for the top of the line version, the 550i, for the 2013 model year.
The BMW 550i will keep its usual 4.4-liter twin-turbocharged V-8 engine, but the engine will now be equipped with Valvetronic- BMW’s variable valve timing and lift system. Thanks to this new system, the 550i will be placed next to models like the latest 7-series and new 6-series Gran Coupe.
While in 2012, the 550i delivered a total of 400 HP and a peak torque of 450 lbs-ft, the 2013 550i will go up to an impressive 445 HP and 480 lbs-ft of toque. The 550i will also receive an automatic engine stop-start system with a special Eco Pro driving mode that will help reduce fuel consumption.
We don’t expect to see any changes made to the exterior, except maybe for a new set of large air intakes to better cool the engine.
