Refined performance, powerful delivery - The new Gran Coupé

The powerful 4.4 liter V8 Bi-Turbo engine develops 397 kW (540 hp), a mighty 730 Nm of torque and viagra overnight delivery is mated to the excellent ZF 8-Speed Sport Automatic Transmission with ALPINA SWITCH-TRONIC for super smooth and canadian health viagra harmonious power delivery. Coupled with BMW’s xDrive technology and viagra propranodol a performance-oriented layout of the all-wheel drive system, this drivetrain delivers exceptional performance. With a 0 - 100 km/h acceleration time of only 3.9 seconds, the new B6 Bi-Turbo Gran Coupé is the fastest accelerating BMW ALPINA to date!

 

First class performance and buy cialis pill economy

The comprehensive high-performance cooling system comprises an indirect inter-cooling system (air-to-water/water-to-air) with short intake tracts and free sample pack of viagra increased inter-cooler flow. The systems excellent thermodynamic efficiency is guaranteed by a large-volume low-temperature inter-cooler radiator, two water-to-air inter-coolers placed close to the engine and cialis professional 20 mg additional separate motor oil and where to buy cialis water coolers. High-performance MAHLE pistons are designed specifically to deal with temperatures and non pescription cialis pressures associated with up to 1.2 bar charging and generic cialis without prescription the engine’s 10.0:1 nominal compression ratio.

 

Altogether, this results in an impressive specific output of 90kW (123hp) per litre and viagra without prescription a mean total compression of 20.1 bar.Direct injection and cost of daily dose cialis VALVETRONIC contribute to the B6 Bi-Turbo’s class-leading consumption and viagra users emission figures: 9.4l/100km (Convertible: 9.6l/100km / Gran Coupé: 10,4l/100km) and 219g/km CO2 (Convertible: 224 g/km / Gran Coupé: 242 g/km) (Combined cycle, measured according to ECE Norm).

 

Transmission – Eight-Speed All-Rounder

Adapted and viagra vs cilias tested in co-operation with ZF, the advanced SWITCH-TRONIC 8-Speed Sport Automatic Transmission sets benchmarks. With ALPINA’s philosophy the guiding credo, engineers have spent thousands of development and viagra sale test hours ensuring that no other performance automatic transmission comes close to providing this level of both comfort and performance.

The blend of eight speeds and plenty of torque makes for unparalleled comfortable gear changes with no noticeable interruption to the delivery of power – only the accom-panying acoustics and the dynamic rev counter provide feedback as to the workings of the transmission.

730 Nm of torque means the B6 Bi-Turbo excels at cruising along at speed in a high gear at minimum rpm, benefiting both consumption and comfort.

 

Using the Sport (S) Shift Mode a completely different character emerges: the transmission is crisp and unmistakably immediate. The innovative single-cylinder fade-out (known as 'Einzelzylinderausblendung‘ in German) enables super quick up-shifts which take just milliseconds. Depending on the load on the transmission, the injection of fuel into a given cylinder is interrupted for a fraction of a second, creating the required reduction in torque that the automatic transmission needs for the up-shift. The advantages versus the typical method of timing retardation are noticeably quicker shifts, improved thermo-dynamic efficiency due to reduced exhaust temperatures and lower fuel consumption. Each up-shift is accompanied by a deep back-pressure 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 allow the driver to take complete control of the transmission. The system allows for multi-simultaneous down-shifts in milliseconds, hereby the transmission will skip several gears depending on engine loads and rpm. In this manner the 8-Speed Sport Automatic Transmission with ALPINA SWITCH-TRONIC reveals itself as extremely multi-faceted, providing the right shift characteristic for any and all situations.

 

The Automatic Up-Shift function means that the transmission will up-shift into a higher gear once a certain rpm threshold has been passed in the current gear. In certain driving situations this may not be desired, for example during especially sporty driving or for example when encountering multiple tight hair-pin corners. The simultaneous selection of either Sport, Sport+ or DSC OFF Mode using the Drive Performance Control button and the selection of the M Shift Mode (transmission) will deactivate the automatic up-shift function. The transmission will hold the selected gear up to maximum rpm’s (electronically limited) and will not automatically up-shift into a higher gear.

 

The intelligent coupling of state-of-the-art engine and transmission technologies give the B6 Bi-Turbo stunning performance figures: 0-100km/h in 4.3s (Convertible: 4.4s / Gran Coupé: 3,9s), and a top speed of 320km/h (Convertible: 317km/h / Gran Coupé: 318km/h).

 

Titanium Exhaust System made by Akrapovic

Special consideration was given to the development of the exhaust system (Gran Coupé: optional).

 

Faithful to the guiding principle of ‘form follows function’, the entire system is noted not only for its acoustics and appearance, but also for its technical refinements. In addition to a weight-saving of 50% compared to the conventional use of stainless steel, the exhaust system also boasts impressive technical details. The engineers from ALPINA and Akrapovic have achieved quite a feat, managing to retain a diameter of 2 x 70mm throughout the entire length of the exhaust system, despite the tricky ‘packaging’. In conjunction with further design refinements, exhaust back-pressure is reduced to an absolute minimum.


In interaction with the powerful engine, the exhaust system generates a backdrop of deep, sonorous eight-cylinder sound – powerful, sporty, but never obtrusive, due to intelligent, controllable exhaust valves. These offer the driver a special degree of influence over the sound experience, and can be controlled using the Drive Dynamic Control. In Comfort+ and Comfort Mode the valves are closed, opening at 3000rpm, regardless of the selected gear. In 1st and 2nd gear decisive use of the accelerator will cause the valves to open (at approx. 60% load) and the B6 Bi-Turbo to elicit a special symphony from the tailpipes during
dynamic bursts of acceleration. As befits the character of the B6 Bi-Turbo in Sport and Sport+ Modes, the exhaust valves remain open at all times.
