Intelligent speed adaptation (commonly known as ISA) continuously monitors the speed limits during driving and if the car’s speed exceeds the speed limit takes action so that it slows down. This can be achieved by simply warning the driver through several methods (including audio) or through an active system which automatically controls the driving systems of the vehicle, making it reduce its speed. The ISA system uses various information about the zone through which the vehicle is going and takes some decisions about what the maximum speed should be. The system knows when the car has entered a new speed zone. It even knows when variable speed zones are in force (for example school zones). ISA can work with temporary speed zones like accident scenes or other special conditions. The Intelligent speed adaptation device is made to help the drivers be on the safe side of the law regarding speed. The system greatly helps the driver when driving through unknown zones or in zones with variable speed limitations.

An intercooler (commonly known as charge air cooler) is a heat exchange device used to increase the intake air charge density of supercharged or turbocharged engines. The intercooler can be air-to-air or air-to-liquid. Intercoolers increase the output of the engine by decreasing the air intake temperature. This decrease in temperature provides denser intake charge for the engine and allows a bigger quantity of air and fuel mixture to be combusted on every engine cycle. Intercoolers come in various sizes, shapes, and designs, depending on the supercharger system they are attached to.

A traction control system (also known as TC) is a system designed to prevent the loss of traction due to excessive throttle or steering. The traction control system is typically an electro-hydraulic system and is somewhat similar with the electronic stability control. However, these two systems do not have the same goal. To prevent the loss of traction, the TC can shut down one or more cylinders or reduce the fuel supply to them. It can also brake one or more wheels and can even close the throttle (in drive by wire cars). The traction control system commonly shares the brake actuator and the wheel speed sensors with the anti-lock braking (ABS) system.

A turbocharger is a forced induction compressor. The turbocharger is in fact driven by a turbine powered by the pressure of the engine exhaust gas. All turbochargers are made out of a compressor and a turbine. The turbine’s wheels rotate because of the pressure of the exhaust gases via the turbine’s inlet. The resulted rotation of the wheel drives the compressor which starts to compress air. Optionally, the compressed air can be delivered through an intercooler system to cool it down because hot air degrades the performance of the engine resulting in a loss of power. The air is pumped through the air intake of the engine and because of the high pressure, the cylinder receives more air. So the objective of the turbocharger is to increase the performance of the engine by increasing the quantity of air the cylinders receive. All this additional air that the cylinders receive requires an increase in the amount of fuel being pumped. This means that a turbocharged system will output from 15 to 40 percent more power at high rotations, but at the cost of fuel. The turbocharger has some security features like the wastegate. This wastegate protects the engine from receiving too much at air at high pressure preventing preignition or engine damages. This system works by sending some of the air away from the exhaust turbine and controls the shaft speed.

If you’re going ‘all out’ to mod your car, stiffened and lowered suspension will be near the top of your list! Lowered cars look purposeful and predatory, often enhancing a standard specification model to look like a racing version. It’s not all about the looks, though, as lowered suspension can also offer vastly improved handling.
Manufacturers design their cars with typical city roads in mind; this means they take into account speed humps and potholes when assigning settings to their suspension. Accordingly, most cars are shipped with relatively soft, bouncy suspension as standard - comfort is everything here, the purpose is to reduce ‘impact shock’ from bumpy roads.

As we all know, alloy wheels can transform a car instantly and dramatically! Replacing your car’s factory fitted 14” steel wheels (and plastic trims) with a striking set of aggressive ‘rims’ can transform your car’s appearance from runabout to ‘coolmobile’!
Until fairly recently, the vast majority of new cars came off the production line with standard 14” or 15” steel wheels and a plastic cover for purely aesthetic purposes (steel wheels are strong and durable, but oh-so-ugly, hence the plastic trims).
Higher end motors, on the other hand, have increasingly been offered with 16” or 17” alloy wheels as standard. Why? It’s simple – alloy wheels enhance a car’s appearance massively. The right set can give your car that prestigious finish and a wider, more aggressive stance. They can also improve handling and performance, as the alloys are considerably lighter and wider than steel wheels.
