Review 2006 BMW Alpina B5

BMW Alpina ALPINA B5 presented at the Geneva Motor Show in March 2005, a car with 500 horsepower, maximum torque of 700 Newton-meters and a maximum speed of 314 km / h - the world's fastest sedan. However, power is not the only characteristic that defines it ALPINA BMW, an automobile which enriches Buchloe the cuisine in both Touring and sedan form

In the end, the key is not absolute power, but the way in which this presentation is in progress. At this point, the youngest member of the family ALPINA deposit with the upper class - like its predecessor, the Alpine history. The legendary B10 Bi-Turbo, for example, is a car that enjoys cult status today

In principle, the B5 uses the same center found a BMW ALPINA B7 family, which is a move to eight cylinders and 4.4 liters. Forced induction engine differs from conventional solutions: it is not the turbo, and the type of super-charger to drain a lot of power to the engine, especially at high revs

A radial or "Nautilus" type of compressor boost pressure provided by the Alpina V8 could be seen as a combination of supercharger and turbocharger. It is powered by the exhaust like a turbo I would, but the belt driven by the crankshaft. The inner workings of the radial compressor compared to the intake side of turbo: a small turbine generates up to 0.8 atmospheres of boost to the cylinders. Before reaching the engine, the air passes through a generous size between cooler, capable of running the air temperature at 70 ° C

Benefits of this innovative technical solution? Radial compressor does not stop, and the time interval when prompted. Less than a low type of partial loads found in everyday driving, the engine runs as if it were aspirated, using all the features Valvetronic (valves). This is a crucial factor in creating advantageous fuel economy. The compressor is controlled by the "upstream" throttle system suction plate - development of a unique mountain, and that makes the collection of Valvetronic V8, without a single throttle body, can also

Looking at the power curve, it is clear what we expect from this engine-bay-filling, complex technology. In a modest 2500 rpm it has 200 horses, and playing. A maximum of 500 horses at 5500 rpm is reached, but the fun does not stop there: the engine maintains 500 horsepower up to maximum speed at 6000 rpm. A very wide power band, there are more than the B5 provides immediate, optimum power

The torque curve is even more impressive. The curve takes the kind of mass of Table Mountain. To be just 1000 rpm, only the minimum, the V8 puts out 300 Nm of torque. Between 4250 and 5250 rpm, is a constant 700 Nm on tap Twist

The engine characteristics, as evidenced by the above figures are of a much larger, naturally aspirated engine. B5 engine is characterized by instantaneous reactions to the entry of gas, regardless of out of control at maximum, and an almost inexhaustible supply of acceleration across the rev range. Second fullsong, BMW Alpina B5 needs but to reach 4.7 100km / h (Touring: 4.8 seconds), placing it in the company right into the world's most renownedsports

Using the enormous power requires high driving art. Taking the pedal is enough, because the BMW ALPINA B5 in possession of a six-speed ZF automatic transmission torque converter, known especially smooth shifts and quick response

The driver can use the transmission in Drive mode, letting the automatic do the movement, or you can manually select the desired speed. SWITCH-TRONIC ALPINA developed several years ago for this purpose. Two buttons on the back of the steering wheel your hands off the wheel to move redundant. The right button shifts up, the left button - enriching the driving experience, and difficult to describe with words

While the manual mode is ideal for driving with confidence through a series of bends or winding roads, it can also help save fuel. We can simply control the transmission to stay in higher speed than the electronic transmission control would select at a given speed. The result: diet extremely low, low fuel consumption - even when you run so sweet, no one will ever need to complain about lack of torque

A review of the deceleration of 200 km / h, the B5's documents braking power to tax as follows: less than 5.5 seconds to a complete stop. Based on the braking system of B7, special attention again placed on comfort braking. For this reason, the brake discs of 374/36mm front and 370/24mm rear dimension are not drilled. Wet braking performance is improved in spite of this, using what is called a "brake-drying" function. From time to time, without the driver feeling that it's always automatic brake pads and lightweight dragged through the rotors, removing any layer of water - and only when the wipers are active. With TEVES 'two-piston floating callipers, extremely strong deceleration and maximum reliability is guaranteed

Wind tunnel, extensive aerodynamic development, testing and attention to detail requirements for a car is safe driving characteristics - even at speeds above 300 km / h. The results are convincing: the values ​​of lift front and rear are minimal, thanks to the ALPINA aerodynamics package. And despite the big wheel / tire combination has a remarkable drag coefficient of 0.29 was reached

By coupling the B5's extremely powerful engine with the comfort of an automatic, ALPINA put the sedan and Touring in a unique position in the high performance segment. This superior performance brilliantly complements a suspension that is itself a combination of precision and comfort, sporty handling that has nothing of the matter-of-fact in the high-performance car. The game between d'entretoises and springs, along with the Michelin Pilot Sport 2 tires (245/40 ZR 19 front, 275/35 ZR 19 rear), communicate a distinct sense of security for the driver for each speed, and at the same time compliance with the requirements for comfort, luxury cars of today. This is all very well in the tradition of the house of ALPINA - a concept refined to perfection with attention to detail

This also applies to a standard equipment level, only some of the extra cost of extras. ALPINE traditional high quality wood and hand-stitched leather interiors, in typical ALPINA Identity, communicate a warm

The BMW Alpina B5 is a synthesis of high performance and driving behavior in the culture
