BMW M550i catches up with M5 in terms of performance
We all know that BMW’s M subdivision specializes in designing powerful and aesthetically pleasing car models. Then there is the M Performance series, featuring similar cars with humbler specs, but at more affordable prices.
Some of these are really similar in terms of raw engine performance, For instance, there is the M550i sedan that comes equipped with a 4.4-liter engine capable of 462 hp (345 kW) and 650 Nm (480 lb×ft) of torque. It only needs four seconds to accelerate from standstill to 100 km/h (62 mph). Its Big Brother, the M5, isn’t really that much more powerful.
To close the remaining gap, G-Power has released an ECU upgrade for the M550i. Once installed, the €2,100 module takes the engine up to 600 hp (447 kW) and 810 Nm (597 lb×ft) of torque. Those who don’t need as much performance may instead opt for a cheaper €1,600 upgrade promising 550 hp (410 kW) and 780 Nm (575 lb×ft).
Available extras include a new exhaust system with a sport-grade catalyst (€4,600) and a set of 21” Hurricane wheels clad in performance tires.
