The new 2016 model year BMW ALPINA B6 xDrive Gran Coupe gains subtle BMW enhancements and benefits in particular from the results of continuous development by ALPINA. The four-door Gran Coupe, already widely recognized for aesthetic beauty and impressive driving performance, raises the benchmark with exciting new details. The new BMW ALPINA B6 xDrive Gran Coupe will become available to order starting in March 2015, with US deliveries slated to begin at BMW Centers in June.
The 4.4 liter V8 Bi-Turbo V-8 engine – known amongst aficionados as the embodiment of power, torque and refinement – now delivers an astonishing 600 horsepower at 6,000 rpm and maximum torque of 590 lb-ft at only 3,500 rpm. The increase in output of 60 hp over the 2015 model has been achieved through extensive rework of the air intake ducting and air filter housing, with enhancements to the fuel supply system. Coupling the BMW xDrive intelligent all-wheel drive system with an ALPINA-developed performance calibration means the new B6 xDrive Gran Coupe delivers heroic straight-line performance. With a 0 – 60 mph acceleration time of only 3.6 seconds, it is the fastest-accelerating BMW ALPINA model ever developed. The new B6 xDrive Gran Coupe is capable of a maximum speed of 200 mph.
The standard equipment level has been extended to include attractive features such as Full LED Adaptive Headlights with High Beam Assistant, and a discrete new B6 model designation in the B-pillar in high-gloss Shadow Line.
The BMW ALPINA B6 xDrive Gran Coupe is available as a special-order vehicle with capacity-limited production underscoring its exclusivity.
BMW M division previews new water injection technology in the latest iteration of the BMW M4 Safety car. Water injection while interesting in theory has its ups and downs. A big downer typically is reliability. However, when it works, it can provide substantial gains through the use of vaporizing water in an intake plenum to cool the intake charger after the heat exchanger becomes heat soaked. The water injection allows for more efficient charge air cooling and sensitive components can be operated with a higher boost pressure. Water injection works by injecting a fine spray of water into the collector which will lower the tendency of the engine to knock, thus enabling the point of ignition to come closer to the optimum value.
As a method to reduce the temperature of the intake air of the new BMW M4, BMW developed a solution to inject a fine spray of water into the intake manifold which will lower the tendency of the engine to knock, thus enabling higher boost pressures and maintaining an optimum ignition point.
As a consequence, this creates a more effective combustion process and at the same time it diminishes the combustion temperature. Since the cool air has a higher density which increases the oxygen content inside the combustion chamber, this means the higher pressure during the combustion process will improve performance and torque. Moreover, the lower thermal strain on the components will increase their lifespan.

The necessary water is stored in a frost-proof five-liter tank located in the M4’s trunk which also incorporates the water pump, sensors and valves which are controlled by the engine’s electronics. The pump feeds water into the injectors at a ten-bar pressure while the volume of water provided depends on the load, engine speed and temperature in order to grant optimal water consumption. BMW M says the water tank must be refilled before any “rigorous action out on the racetrack” while in normal driving on public roads they estimate a water refill once every five stops for refueling without requiring any extra maintenance.
The new water injection allows for outstanding driving properties and impressive performance parameters on the race track for those who demand the most of their M4.

We never thought the day would come… but, BMW has released photos of their latest attempt to fill their product line with as much fluff as possible. Pictured here is the newest, FWD 2-series Gran Tourer. We assume that Gran Tourer brand is an poor attempt to make us think it is not a minivan, but who are they trying to sneak this buy. What are your thoughts? Would you drive a FWD BMW Minivan?
