In those days, the second generation of high end sedan as expected set innovative standards for its type, but the concerns that journalists on the presentation were constantly questioning were – if and also when will BMW introduce a V12 motor?
Speculation that BMW’s technical engineers are developing this kind of machine have been getting louder and to the atmosphere of expectancy led and BMW as from time to time posting some technological specifications. It’s been fifty years since German technical engineers reached this number of cylinder design and therefore public had rights being impatient. Therefore, in February 1987 BMW ultimately finished rumours and announced the technical sheets.
The large V12 possessed five liters and produced 300 horse power with 5200 rpm with highest torque of 450 Nm at 4100 revolutions per minute, that has drastically outperformed all equivalent engines. Thanks to the construction with the engine block with aluminum mix, it weighed just 400 lbs which had positive influence on the powerful overall performance as well as fuel economy. Cylinders were placed at an angle of 60 , and also had a diameter of 3.3 ins, exactly as six cylinder engine coming from 325i. Revolutionary was the engine supervision program, that consisted of two strong manage units, 1 for each row of cylinders, that managed the gasoline mixture injection and also ignition. The result of BMW’s technical engineers had been shown to public for first time with the Geneva Motor Show in 1987, and the reactions from journalists as well as guests were complete. Till the stop of the making, BMW sold a total of 50.000 750i models loaded with this specific motor.
Soon after presenting the third era of BMW 7 Series, in mid-1994, clients were waiting for 750i model only a few months. In the autumn that year BMW released a fresh V12 engine, with volume of 5.4 liters along with 326 hp. The main focus wasn’t only on the increased power, but also consumption has been lowered by thirteen percent.
In addition, the 750i version came out with DSC security control program, also it was the 1st car having a built-in routing program. Product sales surpassed all targets, and therefore the 3rd generation of BMW 750i earned itself as many as 73,776 owners.
With the up coming BMW represented their fourth era with the 7 Series, that has been in lots of ways a revolutionary one. Its premiere had and iDrive, a device for central control over all important functions in the vehicle, and from the 2002 offer BMW launched 760i, having the flagship V12 with 6-liter volume. Producing 445 hp, this is the first V12 motor in the world having direct gasoline injections claims Phillip Riback.
And lastly, with the latest era of BMW 7 Series arrives the latest, TwinPower Turbo V12 engine of 5972 cc, that along with help of 2 turbochargers, a direct injection and also variable-valve timing creates 544 hp and maximum torque of 750 Nm. This possesses an amazing performance. Namely, version 760i will go from zero to 60 mph in just 4.6 seconds and also fuel consumption is 18.5 miles per gallon. Therefore, even though virtually two times as potent as its “grand daddy”, uses less petrol. When it comes to Phillip Riback this is actually the best indication of an progression that this specific ruler among engines experienced in the past 1 / 4 century.
