What Makes a BMW Special?

By: Cyril Joseph

BMW is well known for its technology and design. The style and reliability of these BMW cars make them stand out from the rest. So what exactly makes BMW cars some of the most efficient and stylish on the planet?

The more efficient fuel injector:

You may be aware that horsepower and emissions are both influenced by the fuel injector. The horsepower of any vehicle should be maximized while emissions are minimized. In order to achieve this condition, a rapid burn of fuel is required. This is where the BMW technology excels. They have made a small needle-like valve that injects the fuel forcefully under great pressure into the intake port. The fuel is atomized together with oxygen in the air permitting the fuel to burn quickly and deliver the needed power for your BMW car. The fuel injection system contributes to the great horsepower available in BMW cars.

The BMW ignition coil

BMW engines work on the same principle of other conventional spark ignition engines. However, the spark produced by the spark plugs of a BMW requires a high-voltage electrical charge. This high voltage electrical charge is made available to the spark plugs with the help of the ignition coil. The high voltage spark plugs are used in BMWs to improve the starting performance (the engine can start instantly in any weather condition). The ignition coil operates on the induction principle. It takes power from the accumulator and transforms it into thousands of volts. This high voltage is indispensable for maximum efficiency of the spark plug. This type of ignition coil is the specialty of BMW technology.

The BMW thermostat

The thermostat used in a BMW is another significant part. This device is capable of both measuring and regulating the engine temperature of the car. In order to control the temperature the thermostat will constantly monitor the temperature changes in the Engine. This mechanism works to prevent engine damage due to overheating.

The BMW oxygen sensor

The BMW part that monitors the exhaust condition of the vehicle is the ‘Oxygen’ sensor. This measuring device provides data regarding the quality of the exhaust mix enabling the fuel injection computer to modify the air to fuel ratio to optimize performance. Necessary adjustments are made to ensure the efficient burning of fuel. The better the fuel burns the higher the performance of your BMW car.

All these BMW parts make them one of the most efficient cars in the planet.

The New Ford Ka

The New Ford Car is marketed as small car with big ideas, fun-loving and spontaneous, the Ford Ka lives for the moment. Ford is particularly good at making cars that leave a grin on your face at the end of a journey. And the new Ka does exactly that.

The old model has successfully kept at bay all of its rivals, and has consistently remained the UK's top-selling sub-mini car. When it was launched 12 years' ago, the original Ka had only four rivals, and the sector accounted for just 4 per cent of the UK market.

The new Ford KA is an excellent runner, starts first time, ideal 1st car, cheap to run, low tax, and low insurance group. The new Ka will also be offered with a 1.2-litre petrol engine with 67bhp, which Ford claims has cut fuel consumption by 21 per cent compared to the previous 1.3-litre Ka.

The new Ford Ka is receiving excellent reviews from the media and was recently previewed on BBC's Top Gear showing itself as a real winner.

There is a new 1.2-litre 68bhp petrol engine which Ford claims has cut fuel consumption by 21 per cent compared to the previous 1.3-litre Ka. This also puts the Ka into group B road tax banding, which means you pay only £35 a year. Insurance groups start from a first time driver friendly group 1.

The new Ford Ka is to keep the compact structure characteristic of the older version of the model and, the producer hopes, is likewise going to become as popular among users as the previous version. In the course of 12-year production of the older Ford Ka 1.4 billion cars were produced. And that statistic says a lot about how practical the little Ka is for people who spend their money on a motor.

For now though, you can choose from two engines - a 68bhp 1.2-litre petrol and a 74bhp 1.3-litre diesel. A 1.4-litre petrol is on the cards too, and a Fiat-developed two-cylinder 900cc unit could even appear. Expect to pay from £7k for a Ka when it hits the streets in early 2009.

The New Ford Ka comes in four trim levels - Studio, Style, Style+ and Zetec - with the option of a Bluetooth-enabled connectivity kit, six-speaker CD system and heated windscreen and heated seats. It looks different too - the interior, and in particular the clock, is funky and well made.

The new Ka is practical too, with generous interior space and comfortable accommodation for four adults and their belongings. The high seating position, carefully placed controls and excellent visibility make the Ka a pleasure to drive for drivers of all ages.
Folding the rear seats flat is also easy once the headrests are lowered, thanks to a simple pull lever.
The dashboard layout and use of bright interior colours brightens things up, and the cavernous glove box is great, as it doesn't compromise legroom at all.
Production of the new Ford Ka commences in the autumn of 2008, and the vehicle will go on sale in most major European markets in late 2008/early 2009.

The result is a more sophisticated and grown up small car that looks more substantial but still retains the cheeky fun that is essential to the brand.

Buying cars on-line requires much more reassurance than other on-line purchases. http://www.motorparks.co.uk/
