Cutting-area BMW engine technology blended with in-depth ALPINA development and engineering approach the new BMW ALPINA B5 Bi-Turbo provides on output and torque. The new 4.Four litre 8-cylinder engine with Bi-Turbo charging, Valvetronic variable valve timing and high-strain direct gasoline injection, grants an excellent output of 447 kW (608 hp) among 5750 and 6250 rpm. A most torque of 800 Nm is available from only 3000 rpm.
The resulting overall performance figures are high-quality, accelerating from zero to a hundred km/h in only three.Five seconds, the new BMW ALPINA B5 Bi-Turbo surpasses the 2 hundred km/h mark after simply 11.4 seconds directly to a top velocity of 330 km/h.
The electricity output of this excessive-tech engine unfolds easily and with extraordinary emphasis across the complete rpm range. Excellent throttle response and excessive torque ensure that even at low engine speeds driver inputs are right away transformed into easy acceleration.
A number of vast technical information are liable for the engine's power output and overall performance characteristics - in particular with regards to the air consumption system, the intercooler and the turbocharger configuration in addition to the excessive-overall performance cooling device. The Bi-Turbo charging device contains mainly developed turbochargers placed within the V of the 8-cylinder engine. These characteristic optimized dual-scroll turbocharger housings and compressor wheels with enlarged inlet and outlet diameters. In mixture with as it should be sized mills this configuration guarantees very powerful use of exhaust fuel strength even at low engine speeds. The result is a fast strength build-up and greater torque at decrease rpms for normal high-quality throttle reaction. 670 Nm of torque is to be had at most effective 2000 rpm.
The usual aim during the development of the output associated additives of the ALPINA air intake device - from the so called raw air intake ducts to air filter housings and easy air intake manifold - changed into to reap most de-throttling.
All additives of the excessive-performance cooling system are designed to take away bottlenecks and maximise effectiveness - special large-quantity coolers are interconnected by way of big diameter hosing for optimum throughput. An indirect inter-cooler gadget (air/water/air) helps the implementation of short charge-air intake paths - with a first-rate intercooler providing the 2 huge volume engine-close to intercoolers. Together with additional external water coolers and a transmission oil cooler, the gadget guarantees the thermodynamic balance of the V8 Bi-Turbo engine at all times even under the very best masses and ambient air temperatures.
Inside the engine Mahle pistons and NGK spark plugs are used to deal with excessive temperatures and hundreds related to 1.4 bar charging and a compression ratio of 10.Zero:1.
The stainless-steel ALPINA sports activities exhaust machine with two dual tailpipes is responsible for a discount in returned pressure and a high-quality V8 soundtrack. Active exhaust valves allow the driver to persuade the sound experience by switching between Comfort and Sport Mode. A common ALPINA function: the 2 dual tailpipes of the exhaust system are integrated elegantly and aesthetically into the rear apron.
Fuel intake in the combined cycle measured in step with ECE norms is 10.5 l/100 km, with CO2 emissions of 240 g/km. The new BMW ALPINA B5 Bi-Turbo is already homologated in keeping with the new exhaust emissions popular Euro 6C.
