BMW Alpina B7 Bi-Turbo [Reviwevs]

With the new Bi-Turbo BMW Alpina B7 Alpina introduced the fourth generation of cars based on BMW 7 Series. Most notable predecessors include BMW B7 Alpina B12 6.0 and that has raised the bar in the luxury sedan segment for high performance. New interpretation and the entire state of the art, the BMW Alpina B7 Turbo Drive Bi-exclusive, athletics and comfort in perfect harmony.

Yielding a fine of torque and power will be charged 4.4-liter V8, and, together with an electronically adjustable suspension active roll stabilization, B7 BMW Alpina Bi-Turbo promises to provide the variety of driving experiences so varied that it is unheard of in car of this class. The development of the traditional 20-spoke 21 "Alpina Classic wheels emphasize fresh design language can be found throughout the BMW B7 Alpina Bi-Turbo, and impart a distinctive appearance and a strong attitude.

ENGINE - first class in terms of performance and economy

Bi-Turbo model designation, which now graces the flagship sedan of the BMW Alpina implies greater efficiency and torque-laden than its predecessor, at the same time consumption.

All yields aluminum 4395 cm3 V8 507 horsepower global peak (373 kW) at 5500rpm with a moderate maximum torque of 700 Nm between 3000-4750 rpm. Two turbocharged engines built specifically for Alpina, one located above each of the two banks of cylinders V8, are responsible for forced induction. Turbochargers work in parallel with the turbine blades of generous dimensions of 44 mm and diameter.

The depth of operation of the engine's potential is realized by maximizing the indirect intercooler (air-water/water-air) with routes of entry of short extensions to optimize the flow intercooler. The three heat exchangers, heat exchanger built into the low temperature block heater, and the two engines almost intercoolers are expanded by 35%, which guarantees high thermodynamic efficiency.

High-performance engine pistons are in their work, carefully designed to withstand the forces created by the thermo-dynamic compression 9.2:1 and a maximum thrust turbo 1.0 bar. The result is a huge special power 115hp (85kW) per liter, with a maximum average pressure of 20.1 bar, even among the benchmark established for sports cars.

Other technical intricacies of this high-tech, EU5 evaluated include petrol engine with direct injection and double VANOS. They contribute largely to the B7 BMW Alpina Bi-Turbo is "Best in Class" Fuel Economy l/100km 12.1 [23.4 Imp. MPG], and an emissions rating of 282g/km of CO2 (combined fuel economy according to ECE).

BMW B7 Alpina Bi-Turbo provides evidence in form of its features and technical data, that high levels of performance and fuel economy are not necessarily in favor of a contradiction in terms. Finishing with two dual tailpipes polished stainless steel exhaust system Alpina V8 offers a deep and sonorous, but not intrusive that has come to expect from Alpine.

Powertrain COMFORT - SINGLE SUPERIOR

BMW B7 Alpina Bi-Turbo is the result of the consistent implementation of the philosophy of Alpine, in itself, reason for the strong and elegant BMW B7 Alpina Bi-Turbo shines in everyday use.

A look at the torque and power graph is sufficient to note that BMW B7 Alpina Bi-Turbo accelerates violently yet effortlessly very low revs. The maximum torque is available from an exceptionally wide range of tours, from 3000 to 4750 rpm. This broad power band, coupled with exquisite speed ZF six-speed sports automatic pampers occupants with remarkably high levels of comfort drive smoothly in every driving situation.

Alpine SWITCH-TRONIC, which has been programmed to move exceptionally soft and comfortable to use Auto-shift offers a range of features to suit every taste and situation, through sports and extra-manual mode. Driving the BMW B7 Alpina Bi-Turbo is a completely different experience when using the buttons located behind the steering wheel to manually select the gears of an automatic transmission. In this way the changes come a few hundred milliseconds, and with minimal interruption of transmission of electricity compares favorably to even the best dual-clutch transmissions. As a result, the BMW Alpina B7 Turbo Bi-road speed from 0-100 km / h 4.7 seconds, pressing her with passion electronically limited top speed of 280 kmh. Although there is rarely need such a hurry, ventilated and generously proportioned (374 mm in diameter.

front 370 mm rear) high performance brake system guarantees deceleration on an equal footing with pure sports cars.

Suspension - harmony, time, attractive, rich

Gone are the days when a trip purely "hard and sports" was a deliberate feature of suspension set-up. The search for truly neutral is still a smart way to proceed, resulting in better what is technically possible. In achieving this goal, a little 'shorter springs individually calibrated to reduce the ride height front and rear by 15 mm and 10 mm respectively.

Together with 21 "suspension wheel and tire combination is both sensitive to inputs and direct sense, but without the harshness of a pure suspension sportsoriented through the large living room with an agility usually associated with only very minor sport sedans . The lightweight 21 "wheels, with their new interpretation of the design Alpina CLASSIC wheels shod with specially selected offset introduced MICHELIN: 245/35 R21 285/30 R21 front and rear. Previous Run-Flat technology, conventional tires used to ensure a smooth and comfortable sophistication that is rare today.

Alpina has integrated state of the art-technology electronics and clever suspension, subtly adapting the strict requirements of our customers. As part of standard equipment BMW Alpina B7 Bi-Turbo, you must enable the suspension system with Electronic Damping Control and Dynamic Drive Dynamic (active roll stabilization) driver to choose between three different suspension settings: Comfort, Normal and Sport. They are deliberately calibrated to give distinctly different set-ups that affect the characteristics of the damper, active roll stabilization and the parameters of the assist power steering, throttle response algorithms and amortization expense of reversal. BMW Alpina B7 Bi-Turbo offers unprecedented versatility driver that provides comfort over long distances as easily as the back road pace, always with maximum pleasure and safety.

Experienced riders are not prevented from pushing the BMW Alpina B7 Bi-Turbo unit at the limit: sport, more so automatically changes the traction control systems on the Dynamic Traction Control (DTC), an extension of the DSC. This helps drive change over the wheel and a delayed response by the traction control system.

Design and Interior - Scalable up to the last bit

In the dynamic, elegant and powerful -. The silhouette of the BMW B7 Alpina Bi-Turbo is significantly influenced by the evolutionary design of new 21 "Alpina wheels CLASSIC A turbine-type three-dimensional curved guides of each of the 20 rays from the center of the wheel rim, when they have a machined surface. Depending on the angle of the observer is the speed of rotation of the wheels and the light, the look of this classic wheel changing. Of course, they still have the tire valve refined air, safely and in style behind lockable covers.

In real life, "form follows function" of fashion, a typical combination with Alpina front of Fresh-air transmission system and engine oil cooler, which is separated from the main module cooling system to improve efficiency. Design of the front and rear spoilers and aerodynamically-oriented benefits, reduces lift on the front and back of 30% and 15%. To the left and right, the exhaust system with two dual tailpipes are perfectly integrated into the rear skirt, and saw the BMW B7 Alpina Bi-Turbo power.

By climbing into the BMW B7 Alpina Bi-Turbo, we see immediately Alpina side skirts, which is finely illuminated in blue. The SWITCH-TRONIC steering wheel, 385mm in diameter, and the gloved hand in the finest, most comfortable leather LAVA Lina. In view of the driver, with red needles on a field instrument cluster ring of blue, where a Black LCD panel is responsible for notifying the driver with important information.

Optional inside Alpina piano lacquer with his money, lozenges diagonally, offers a modern alternative and equally exclusive.

Discrete metal emblems adorn the upper seatbacks Alpina leather seating comfort, as standard equipment a full metallic paint or a navigation system with Bluetooth telephone preparation.

Even the engine compartment is a subtle signature in an orderly manner by presenting a new design Alpina engine cover.
