The horsepower is a parameter that most of us take into consideration at first when buying a car. In this comparison it is the Chevrolet which has by 30 percent more horsepower in comparison to the Smart Forfour 1.0 63HP. Therefore the Chevrolet is able to reach higher maximum speed. Due to more horsepower the Chevrolet Kalos should as well provide noticeably better flexiblility in specific gears.
The Chevrolet Kalos 1.4 82HP manual is 128 millimeters longer in comparison to the Smart. Long vehicles have more interior space and usually have plenty of trunk space. Although the Chevrolet Kalos seems to be better choice for families or those who appreciate comfortable rides that make them feel fresh and relaxed upon arriving, the Smart Forfour may appeal to city drivers because it will not cause troubles with parking and will have smaller turning radius.
Number of doors
A five-door car usually is a hatchback and as a result the Chevrolet Kalos 1.4 82HP manual, where you can open up the boot lid and fold flat the back seats enlarging a luggage compartment, has an advantage on the 4-door Smart which in turn has a smaller trunk cut off from the passenger compartment.
The higher a vehicle is, the better is the comfort of boarding it and greater capacity of carrying big amount of stuff to it. The difference of 3 % in favor of the Chevrolet Kalos is small and should not be really noticeable.
