The horsepower is a characteristic that majority of car fans pay the biggest attention to. In this case, it is the BMW 3-Series E90 Limousine E90 that has by 23 horsepower more in relation to the Alfa Romeo, which makes this car slightly better in terms of high speed. Having more horsepower the BMW 3-Series E90 will as well give a bit more flexiblility in specific speeds.
The fuel economy is considerably to BMW 3-Series E90's advantage. This automobile uses 33 percent fewer fuel in the combined cycle in comparison to the Alfa Romeo. Bear in mind that average fuel consumption in the combined cycle for the middle segment, in which the BMW is classified, equals to 7.7 l while the BMW 3-Series E90 Limousine E90 consumes by 31 % less fuel than the average.
Thanks to 95 percent more torque, the engine of the BMW does a much better job of transmitting power to the wheels than the Alfa Romeo. This, in turn, have positive implications for a car's acceleration.
The BMW burns up 25 % fewer fuel while driving inside city in comparison to the Alfa Romeo 159 Sedan 1.8 MPI 16v 140HP manual. The difference at the level of 25 % is quite appreciable in everyday usage of the car. What is more, in a long run it will bring you significant savings. Keep in mind that fuel consumption may change depending on your driving style
Acceleration 0-100 km/h
The Alfa Romeo is relatively slower compared with the BMW 3-Series E90. The
difference in the amount of
1.9 s is
quite low and for that
reason it should
not be substantially taken into
consideration when choosing
one of presented
The maximum velocity possible to be reached by the BMW 3-Series E90 Limousine E90 is greater as compared to this of the Alfa Romeo 159 Sedan 1.8 MPI 16v 140HP manual which allows to drive the same distance on the highway in shorter period of time. The difference at the level of 19 kilometers per hour is small and is not realy noticable in daily use.
Maximal torque RPM
The RMP where the maximum torque is reached tells us how fast an engine reaches its best output with increase in rmp. The lower rotational speed or the longer range in which the torque has the highest value, the more the engine is flexible and the kick of acceleration is felt earlier.
The wheelbase of a car is the distance separating its front and rear wheels. The wheelbase notably affects the driving due to more appropriate car's weight distribution. BMW 3-Series E90 Limousine E90 has 68 millimeters longer wheelbase distance in relation to Alfa Romeo. Wheelbase dimensions are important to the stability and steering. Thus, the mass of BMW 3-Series E90 should be better distributed and driving should be smoother and safer.
Number of gears
The BMW 3-Series E90 Limousine E90 320d EfficientDynamics 163HP manual have a higher gear count than the Alfa Romeo 159 Sedan 1.8 MPI 16v 140HP manual which means
that BMW 3-Series E90 Limousine E90 320d EfficientDynamics 163HP manual would have
better acceleration and better fuel
economy. But the difference is not big and unless you are drag
racing at a timed event you would not even
notice the difference.
The BMW 3-Series E90 Limousine E90 has 11 percent larger engine capacity in comparison to the Alfa Romeo 159. For the reason that the difference is not big, the BMW should accelerate only slightly better, assuming that other paramerters are the same.
If you are a tall man or you happen to carry in the trunk stuffs of large size, the BMW, which is by 2 millimeters higher than the Alfa Romeo 159, would be appropriate choice for you. However, presented cars do not differ much it the aspect of its height and it should not be much noticeable.
