After a multitude of car comparisons between the top premium brands, here comes today another head-to-head race between BMW and Mercedes, but this time, at the engine unit level. BMW’s highly acclaimed 4.4 liter V8 twin-turbo that powers the X5 M and X6 M SAVs, goes into the battle field against a worthy opponent, 5.5 liter V8 twin-turbo from Mercedes-Benz.
The comparison was put together by TopSpeed who also tells us more about the two performance engines. Starting with a famous quote by Carroll Shelby, horsepower sells cars
, torque wins races, the article continues with a brief description of the two engines.
While BMW’s 4.4 liter power unit is fairly known to the BMW community, owners and future buyers, the unit coming from Mercedes has yet to make an official appearance.
Remember the words of performance guru Mr. Carroll Shelby: Horsepower sells cars, torque wins races. Mercedes Benz surely remembers and they have taken the queue to come out on top with the launch of their revolutionary 5.5L V8 twin turbo engine. Slated to make appearances in the CL, CLS, S, and E class, this new unit had the numbers of horses increased to 537.
But the real value of this engine comes from the increased output in torque levels which has gone up from 630 Nm as seen in the previous 6.3 V8, to 900 Nm.
Very high numbers when compared against BMW’s upcoming M5 and its modified 4.4 liter V8 engine, and certainly, they would make for an interesting race between the two.
Fuel consumption numbers? To be determined….[Source: TopSpeed ]
