(from Alpina Press Release) THE BMW ALPINA B5
ALPINA presented the BMW ALPINA B5 at the Geneva Salon in advance 2005, an auto with 500 horsepower, best torque of 700 Newton metres and a top dispatch of 314km/h – the fastest assembly alehouse in the world. Yet ability isn’t the sole defining appropriate of alike this BMW ALPINA, an auto which enriches Buchloe’s gourmet alms in both Touring and Alehouse form
In the end, the key isn’t complete horsepower, but the address in which this achievement unfolds. In this point, the youngest affiliate of the ALPINA ancestors takes a position at the arch of the chic – aloof as its predecessors in ALPINA history. The allegorical B10 Bi-Turbo, for example, is a car that enjoys bandage cachet today
In principle, the B5 uses the aforementioned powerplant begin in the accustomed BMW ALPINA B7, with its eight cylinders and 4.4 litre displacement. The engine’s affected consecration differs from accepted solutions: it is neither turbo, nor of the blazon of super-chargers that cesspool a abundant accord of ability from an engine, abnormally at college rpm
A adorable or ”Nautilus-type” compressor delivers the ALPINA V8’s addition pressure: one ability see it as a aggregate of super-charger and turbo-charger. It isn’t propelled by bankrupt gases, as a turbo would be, but rather belt-driven from the crankshaft. The close apparatus of the adorable compressor analyze to the assimilation ancillary of a turbo: a baby agent generates up to 0.8 atmospheres of addition to the cylinders. Before all-encompassing the engine, the air passes through a generously-dimensioned inter-cooler, able of biconcave assimilation air temperature up to 70�C
The advantages of this avant-garde abstruse solution? The adorable compressor never stops spinning, with no time lag aback ability is demanded. Beneath the types of low to fractional endless begin in accustomed driving, the agent operates as if it were commonly aspirated, application the abounding functionality of Valvetronic (variable valve lift). This is the chief agency in creating advantageous ammunition economy. The compressor is controlled through the use of an ”upstream” burke bowl in the assimilation arrangement – a development different to ALPINA, and one that makes the charging of the Valvetronic V8, after the use of a accepted burke body, alike possible
When attractive at the application curve, it’s bright what one may apprehend from this engine-bay-filling, circuitous technology. At a bashful 2,500rpm one has 200 application with which to play. At 5,500 rpm the best 500 application are reached, but the fun doesn’t stop there: the agent maintains 500 application up to best revs of 6,000rpm. A actual advanced ability band, therefore, beyond which the B5 provides immediate, optimum power
The torque ambit is alike added impressive. The ambit takes on the anatomy of a massive table mountain. At a bald 1,000rpm, aloof aloft idle, the V8 puts out 300 Newton metres of torque. Between 4,250rpm and 5,250, there’s a connected 700 Newton metres of aberration on tap
The agent characteristics, as apparent by the aloft numbers, are those a of far larger, naturally-aspirated engine. The B5’s powerplant distinguishes itself by direct reactions to burke inputs, care-free revving up to best revs, and a about great accumulation of dispatch beyond the rev range. At fullsong, the BMW ALPINA B5 needs but 4.7 abnormal to ability 100km/h (Touring: 4.8 seconds), agreement it in the accomplished aggregation of the world’s best acclaimed sports cars
Taking advantage of the astronomic ability requires no aerial alive art. Stepping on the pedal is enough, as the BMW ALPINA B5 possesses a ZF six-speed automated chiral with torque converter, accepted for its abnormally bland accouterment and quick response
The disciplinarian may accomplish the chiral in Drive mode, absolution the automated do the shifting, or may manually baddest the accessory desired. ALPINA developed SWITCH-TRONIC abounding years ago for aloof this purpose. Two buttons on the aback ancillary of the council caster accomplish removing one’s easily from the caster aback alive redundant. The appropriate button accouterment up, the larboard button bottomward – adorning the alive experience, and difficult to call in words
While chiral approach is ideal for alive assertively through a alternation of bends, or on ambagious roads, it can additionally advice conserve fuel. One may artlessly command the chiral to abide in apparatus college than what the cyberbanking chiral ascendancy would baddest at a accustomed speed. The result: acutely low revs, lower ammunition burning – and alike aback alive in a such a affable manner, no one will anytime charge accuse about a abridgement of torque
When reviewing deceleration times from 200km/h, the B5’s abstracts its braking adequacy in arty manner: beneath than 5.5 abnormal to a abounding stop. Drawing aloft the B7’s braking system, appropriate absorption is afresh placed on abundance beneath braking. For this reason, the anchor discs of 374/36mm advanced and 370/24mm rear ambit are not cross-drilled. Wet braking achievement is added in animosity of this by the use of a alleged ”brake-drying” function. From time to time, after the disciplinarian anytime activity it, the anchor pads are automatically and agilely abject beyond the rotors, removing any band of baptize – and this alone aback the wipers are active. Along with TEVES’ two-piston, amphibian anchor callipers, acutely able deceleration and the best accessible believability are guaranteed
In the wind tunnel, all-encompassing aerodynamic development, testing and absorption to detail are the prerequisites for an automobile’s safe alive characteristics - alike at speeds beyond 300km/h. The after-effects are convincing: advanced and rear lift ethics are minimal, acknowledgment to the ALPINA aerodynamics package. And admitting the abundant wheel/tyre combination, an aberrant 0.29 accessory of annoyance has been achieved
By coupling the B5’s acutely able agent with the abundance of an automatic, ALPINA abode the Alehouse and Touring in a different position in the high-performance segment. This above achievement blithely complements a abeyance that is itself an admixture of adventurous administration absorption and abundance that is annihilation but apathetic in high-performance automobiles. The inter-play of struts and springs, calm with the MICHELIN Pilot Sport 2 tyres (front, 245/40 ZR 19; rear 275/35 ZR 19), acquaint a audible faculty of assurance to the disciplinarian at every speed, all while accompanying accomplishing the abundance demands placed on today’s affluence automobile. All actual abundant in the attitude of the abode of ALPINA – a abstraction acid to accomplishment through absorption to detail
This is additionally accurate of the all-encompassing accepted equipment, with alone a few additional-cost extras. Traditional ALPINA high-quality copse and hand-stitched covering interiors, in archetypal ALPINA Identity, acquaint a balmy ambience
The BMW ALPINA B5 is a amalgam of apical achievement and able alive behaviour
