All-wheel-drive car BMW X5 2006. Not so long ago we introduced readers to a BMW X5 of the company Bayerische Motoren Werke, first unveiled at the 1999 Detroit auto show. The first in the history of the company four-wheel drive SUV with a distinctive sporty character caused a sensation in the automotive world. However, the producers didn’t call him neither a jeep nor an SUV nor a crossover: BMW X5, they took to the specially designed class of vehicles called SAV (Sports Activity Vehicle), which translated to English means something like “sports-active car”.
BMW X5 of the sample in 1999 was so well-established machine, that the release in 2006 of the same name the new car was to his fans a complete surprise.
The assumption that buyers are offered a restyled version of the car the end of the last century, turned out to be wrong — the firm has developed a completely new machine, using all of the same ideological concept of the SAV.
The car was at 187 mm longer and 61 mm wider than its predecessor, and its wheelbase has increased by 113 mm. However, the X5 retains the basic proportions and brand awareness.
Of course, the system, well proven in previous versions of the car, moved to a new machine. They include, for example, the intelligent all-wheel drive system, called xDrive, the principle of which is based on the fact that torque is redistributed between the front and rear wheels, and higher torque is instantly routed to where most needed. The xDrive system consists of two main devices — a Central multi-plate clutch with electronic control, which distributes torque between the axles and the system of exchange rate stabilization DSC, which governs efforts directed at individual wheels.

Normally, when driving in a straight multiplate clutch partially closed, which allows to bring the front wheels about 40 percent of the total torque. In the process of moving the electronics depending on the conditions continually redistributes torque to the front and rear axles, while the response speed of the actuator is 100 milliseconds.
But in addition to the “old” devices to the equipment of the X5 of 2006 is a fundamentally new. One of them primarily include the AdaptiveDrive system, which controls all elements of the suspension — active anti-roll bars and active (changing stiffness) dampers. Their work is controlled by the computer that receives from a number of sensors information about what is happening with the car, and independently change the characteristics of the active elements, providing a constant horizontal position of the body relative to the road. In particular, the system enables AdaptiveDrive to completely rid the car of roll in corners. However, to manage all these devices on the vehicle with a high center of gravity had to use the new FlexRay system with an enlarged 20 times the throughput from 0.5 to 29 MB/s, which allowed to reduce the reaction time of active dampers with 10 to 2.5 milliseconds.
Interested consumers and active steering system Steering control Activ, which before the advent of a new X5 established a firm solely on the sedans and coupes. The essence of this system is that at higher speeds the gear ratio from the steering wheel to the front wheels becomes large (i.e., from lock to lock the steering wheel has to make more rpm) and at low (in particular when maneuvering in the Parking lot, etc.) — umenshenie. As experts say, at high speeds the steering wheel becomes dull, and small, acute.
The body design of the BMW X5. Its main parameter is the static torsional rigidity — is 27 000 Nm/deg.
The new turbodiesel engine displacement of 2993 cm3 and a power of 235 HP equipped with Common rail third-generation and turbocharger with variable geometry
Diesel 8-cylinder engine displacement of 4799 cm3 with a V-shaped arrangement of cylinders develops power of 355 HP
A new six-speed automatic transmission type ZF compared to “automatic” previous generation has twice the response speed
Control of the automatic transmission is a miniature electronic joystick
Compared to the X5 the end of the last century, has changed and range of engines, which are fitted in the car of the XXI century. Instead of a gasoline V-shaped 8-cylinder engine working volume of 4.4 and 4.8 l are left only with the latter, the power of which is 355 HP. It is equipped with a throttle-free Valvetronic system, which meters the amount of fuel-air mixture to the stroke of the valve system, infinitely variable adjustment of the phases of the Double Vanos. All these systems have reduced the fuel consumption about 1 l/100 km.
In addition, the X5 can be equipped with two engines working volume of 3.0 l diesel, 235-horsepower, diesel, power 272 HP compared to similar engines of its predecessor, the new have increased in power (respectively, 17 and 41 HP) and “thin” (in particular, diesel — 25 kg). By the way, the turbodiesel engine equipped with Common rail the third generation with piezo injectors, capable of injecting fuel into the cylinders under a pressure of 1600 atmospheres. The fuel is injected into the combustion chamber of four times per clock — double pilot injection, main and extension. First make the combustion process more uniform and incremental reduces the toxicity of exhaust gases. The maximum torque of the engine 45 Nm higher than that of gasoline 4.8-liter, due to the variable geometry turbocharger.
The all-new X5 are equipped with a six-speed automatic transmissions ZF, which already passed the test on the new BMW 335i coupe. By the way, among the first generation of the X5, only 5 percent of cars were equipped with manual transmission. According to experts, the new speed automatic transmission, compared to the old, has doubled.

The brakes on the X5 deserve special praise. The operation of the ABS and the above-mentioned Activ Steering (active steering) ensures smooth deceleration of the vehicle. Even when braking the car, the left wheels of one of the parties on a slippery patch, the wheel turns slightly in his direction, which prevents uncontrolled rotation.
Parking brake at X5, like many modern machines, electronic. To put it into action, the driver should press the button located between the front seats. Unfortunately, when pressing on the gas pedal the car is not removed from the “Parking brake” as it happens on almost all vehicles with electronic Parking brake. To released the X5, you need to simultaneously press the “Parking brake” and the brake pedal.
BMW X5 as standard — a five-seater, however, the majority of cars shipped to the U.S. market — the seven-seater. In Europe, an additional pair of seats is an option, operable by order. Available in salon instead of standard chairs can be set sports, with adjustable lateral support and ventilation. As options are also available, rear dual-zone climate control and heated seats.
Technical characteristics of the car BMW X5
The amount of Luggage you have, the X5 is 620 litres — compared with the previous generation increased by 110 liters When folded seats of the second row Luggage capacity increases to 1,750 L. Under the boot floor is quite spacious compartment designed for tools and small things, not related to the Luggage.
Wheels-have a spare car is not provided — X5 is equipped with Run flat tires, which after a puncture you can drive at least 150 km at a speed of 80 km/h!
Off-road capabilities all-wheel drive Sports Activity Vehicle leave much to be desired. And no wonder — the car is not provided neither underdrive nor locking differentials… and the ground clearance of the car of such dimensions and weight of over two tons is obviously small, only 212 mm is even smaller than the domestic “Field”. So experts do not suggest for the AWD X5 to leave such a familiar asphalt.
New “sports-active car” will be the same as the predecessor, to assemble at the plant of BMW in the us city of Spartanburg (South Carolina). The reason is simple — more than half of the production of X5 is implemented in the United States.
A few words about this enterprise. In the unanimous assessment of experts, the plant in South Carolina is a recognized world record holder in automotive engineering on the speed of running of the machines. C the Assembly line of the plant went to a BMW 3-series, then series, Z3, X5 and Z4.
The area of this plant is about 420 hectares, the number of employees over 4,700 people. This enterprise, which has the highest in the world automotive industry degree of automation, use of modern production methods according to the scheme just-in-time (in English — just in time). The components come from local suppliers in the same moment and in the place where they are needed. The work is conducted in groups that accompany the car throughout the production process and perform all the necessary operations before the vehicle enters the area of responsibility of another group. Welding, transportation, and quality assurance engaged in the enterprise more than 100 robots.
According to representatives of BMW, the three-liter version of the X5 sold in America for 45 $ 900, and the car with the engine and 4.8 i — 54 for $ 500. In Russia, the car can be purchased for 84 000 — 150 000 dollars. Feel like telling the difference!
