By engine tuning we understand the adjustment brought to engines to yield optimal performance. This performance can either regard the power output or the fuel consumption. The adjustment of the carburetor and the ignition system can be called tuning, as well as significant engine enhancements. The common known engine tune-up is a routine service in which an engine is restored to its optimum performance. Manufacturers recommend tune-ups for the cars to run as expected. You will not need a tune-up for about 160,000 kilometers or 10 years for a modern car.

Four-wheel drive (also known as 4WD or 4×4) is a vehicle in which all the four wheels are allowed to receive torque from the engine at the same time. The term is widely associated with off-road driving. In fact, by powering all of the four wheels at the same time, a normal car has a better control on most surfaces. The term four-wheel drive describe cars in which the driver has to manually switch between two wheel drive (for streets) and four-wheel drive (for adverse conditions such as snow, ice, mud, gravel). AWD (All Wheel Drive) is a “full-time” four-wheel drive.

John W. Hetrick of Newport, Pennsylvania, USA invented the first airbag in 1952. He patented this new device in 1953. Nowadays, airbags are also called Supplementary Restraint Systems (SRS) or Supplemental Inflatable Restraints (SIR). Airbags are designed to complement the seatbelts in case of a collision. The airbag is very useful and approximately 400 lives are saved per year. Also, case studies show that the fatality percentage in case of a car accident is reduced by 8 percent. So this device is a must-have for any car. Almost all car producers implement airbags in most of their car designs so you can be better defended against injuries to the head and/or upper body.
