Video: ALPINA B5 BiTurbo with 540 horsepower
ALPINA releases a video of the B5 BiTurbo model. The super sporty B5 is based mostly on the F10 five Series and is powered by a tuned up V8 4.four liter engine with two Honeywell-Garrett turbochargers that produces 540 horsepower and a optimum torque of 730 Nm. This is 33 hp and 30 Nm larger than the ALPINA B5 Bi-Turbo exposed final year.
The full power is reached at 5,200rpm and the maximum torque of 730Nm is obtainable from two,800 to four,500rpm. The updated D5 BiTurbo runs to a hundred km/h in 4.three seconds (.two seconds faster than previous model) and the best speed is reached at 320 km/h.
The engine is mated to a ZF SWITCH-TRONIC 8-speed Sport Automatic Transmission.
THE POWERTRAIN – Very first CLASS Efficiency AND Economic climate
The new all-aluminium V8 powerplant generates 540hp (397kW) at a moderate 5200 to 6250rpm, with optimum torque of 730Nm offered amongst 2800 and 5000rpm. “Bi-Turbo” refers to two turbo-chargers configured in parallel, each and every feeding one particular of the two cylinder banking institutions. Specially developed large diameter exhaust-turbines allow this engine configuration to supply each exceptional energy output and an abundance of torque more than an particularly broad rpm range while preserving superb throttle response at reduced rpm.
The extensive large-performance cooling technique comprises an indirect inter-cooling method (air-to-water/water-to-air) with brief consumption tracts and elevated inter-cooler flow. The methods superb thermodynamic efficiency is guaranteed by a huge-volume low-temperature inter-cooler radiator, as effectively as two water-to-air inter-coolers positioned close to the engine.
High-efficiency MAHLE pistons are created particularly to deal with temperatures and pressures related with up to 1.two bar charging and the engine’s 9.two:one nominal compression ratio. Altogether this benefits in an impressive certain output of 123 horsepower (90kW) per litre and a mean complete compression of twenty.one bar.
Direct injection and Double-VANOS contribute to the B5 Bi-Turbo’s class-top performance, emissions and financial system in this section: ten.5l/100km (Touring: ten.6l/100km) and 252g/km CO2 (Touring: 255g/km) (Combined, measured according to ECE Norm).
TRANSMISSION – EIGHT-SPEED “WUNDERKIND”
Adapted and tested in co-operation with ZF, the superior SWITCH-TRONIC eight-speed Sport Automatic Transmission sets a new benchmark. With ALPINA’s philosophy the guiding credo, our engineers have spent 1000′s of advancement and check hours making certain that no other functionality automated transmission comes near to offering this level of each comfort and performance.
The blend of eight speeds and plenty of torque can make for unparalleled comfortable gear modifications with no noticeable interruption to the delivery of electrical power – only the accompanying acoustics and the dynamic rev counter give feedback as to the workings of the transmission. 730Nm of torque implies the B5 Bi-Turbo excels at cruising along at speed in a large gear at minimal rpm, benefiting the two consumption and comfort.
Using the Sport (S) Shift Mode a fully diverse character emerges: the transmission is crisp and unmistakably instant. The innovative single-cylinder fade-out (acknowledged as ‘Einzelzylinderausblendung‘ in German), allows super quick up-shifts which consider just milliseconds. Depending on the load on the transmission, the injection of fuel into a offered cylinder is interrupted for a fraction of a second, producing the necessary reduction in torque that the automatic transmission needs for the up-shift. The positive aspects versus the standard strategy of timing retardation are noticeably quicker shifts, improved thermo-dynamic efficiency due to reduced exhaust temperatures and lower fuel consumption. Every single up-shift is accompanied by a deep back-stress burble.
The SWITCH-TRONIC buttons, for use in the Manual (M) Shift Mode, are ergonomically and unobtrusively positioned on the back of the steering wheel, and enable the driver to consider total management of the transmission. The program enables for multi-simultaneous down-shifts in milliseconds, hereby the transmission will skip many gears based on engine loads and rpm. In this manner the 8-speed Sport Automated Transmission with ALPINA SWITCH-TRONIC reveals itself as very multi-faceted, delivering the proper shift characteristic for any and all scenarios.
The Automatic Up-Shift function means that the transmission will up-shift into a increased gear the moment a certain rpm threshold has been passed in the current gear. In specified driving conditions this might not be sought after, for instance during specially sporty driving or for example when encountering multiple tight hair-pin corners. The simultaneous selection of both Sport, Sport+ or DSC OFF Mode making use of the Drive Dynamic Handle button and the selection of the M Shift Mode (transmission) will deactivate the automatic up-shift funtion. The transmission will hold the picked gear up to optimum rpm’s (electronically restricted) and will not immediately up-shift into a increased gear.
The intelligent coupling of state-of-the-art engine and transmission technologies give the B5 Bi-Turbo beautiful efficiency figures: -100km/h in four.5 seconds (Touring: four.6) and a top speed of 319km/h (Touring: 316km/h). Enormous braking capability in the kind of ventilated substantial-overall performance brakes (374mm front, 345mm rear) assures braking on par with pure-bred sports cars.
SUSPENSION – DYNAMIC COMFORT
The instances when „properly stiff„ suspensions have been witnessed as a positive dealing with characteristic are prolonged gone. It remains a truth that a genuinely neutral set-up, even at the restrict, gives the greatest technical compromise. This is achieved in component through shorter ALPINA springs and precise transverse suspension arms which in mixture result in an optimised camber. With each other with 20” wheels and tyres this yields a extremely balanced and direct chassis set-up, discarding a pure sport-orientated strategy for an agile suspension with pre- cise turn-in. Mounted on the light-weight 20” ALPINA Traditional wheels are non-run-flat MICHLIN PILOT SUPER SPORT tyres measuring 255/35 ZR20 front and 285/30 ZR20 rear. Representing the latest in ultra-higher functionality tyre technologies accessible today, they feature a running surface is produced up of 2/3rds soft compound (centre) and one/3rd difficult compound (outside and flanks). This mixture helps make for exceptional sturdiness in spite of typical hard use in high-efficiency cars yet gives very very good grip in the wet. Enhanced tread stability and a new flank reinforcement technologies make sure the tyre is much less most likely to suffer from spikes in temperature with a resulting reduction of grip in the dry.
To fulfil the seemingly contradictory demands for comfort, everyday usability and sports auto like handling, the B5 Bi-Turbo is outfitted with electronically-adjustable dampers (Variable Damper Management). This method has been artfully calibrated by ALPINA, and is tied into other technique parameters controlling steering support, torque cushioning and the Dynamic Stability Management technique. Featuring pronounced Comfort, Normal, Sport and Sport+ modes, the B5 Bi-Turbo transitions effortlessly from cultivated luxury to thorough-bred sportiness. Light steering, ultra-comfy suspension and an imperceptibly shifting transmission make the B5 Bi-Turbo an best partner in halt-and-go traffic, when covering fantastic distances or when encountering less than perfect road surfaces. Nevertheless at the touch of a button, the B5 Bi-Turbo will track by way of tricky corners and exciting sections of road with an agility and light-footedness like no other in its class.
An especially for the BMW ALPINA B5 Bi-Turbo in co-operation amongst ALPINA and Drexler Motorsport adapted restricted-slip differential is accessible as an choice. This mechanical restricted-slip differential improves traction for the duration of dynamic driving and minimises slip by distributing torque and electrical power to the wheel with the most grip. The opera- tion of the limited-slip differential is long term and independent from other driving dynamic settings or techniques. Substantial characteristics contain: torque sensing multidisc differential with pre-tensioning energetic locking characteristic up to 30 % under load and 20 % beneath trailing throttle really reactive in sensing slip, harmonious self-steering properties and superb directional stability motor sport quality, forged gears, CNC milled housing, hand developed.
Design and style & INTERIOR – Classic CRAFTSMANSHIP MEETS Contemporary Engineering
The B5 Bi-Turbo presents typical ALPINA virtues and layout cues in a new and convincing trend, with a refreshing and dynamic physical appearance. Each the saloon’s and the touring’s silhouette begins with an focus commanding front that is highly effective and confident, and ends with a harmonious and stylish rear. The ALPINA trademark two double-ended-pipes are artfully integrated into the rear valence which attributes a discreet diffuser. The diffuser can be deleted as required, ought to the consumer want the optional capacity to tow a trailer. In mixture with the rear spoiler (Saloon), the B5 Bi-Turbo’s complete aerodynamic package yields the highest levels of safety and stability, specifically at substantial speeds. The resulting reduction in lift, speed-dependent, can reach a remarkable –60 % front and –30 % rear.
The interior reveals the expected discreet touches that propose the B5 Bi-Turbo’s unique pedigree. The normal gear level is complete: leather interior, versatile and adjustable Comfort seats, an superb navigation method with Bluetooth preparation, and Xenon headlamps all ensure the driver’s and passengers’ nicely-getting. The hand-stitched LAVALINA leather SWITCH-TRONIC steering wheel can be positioned exactly as essential to see the blue ALPINA gauges with black-panel LCD technolo- gy, thanks to the electrically-adjustable steering column. The classic ALPINA burled Myrtle wood trim supplies a warm ambience – discovered only on the USA’s Pacific Coast it is cultivated from dedicated Laurel tree groves grown for just this function. Optional ALPINA Piano Lacquer interior trim with its silver diagonal rhombs, provides a modern day and just as exclusive substitute.
The interior’s warm ambience and modern-day therapies foster a sense of effectively-currently being. For individuals who would only award themselves that a thing special, unique volumes and the ALPINA philosophy of hand-craftsmanship provide a virtually countless spectrum of personalisation.
