Now all short cut, not question for Lamborghini push the downsizing in the extreme and added a small 6 cylinder in the New Lamborghini Aventador LP700-4. However, a system to cut cylinders on the V12 would be on the ranks.
With force praises and warm Gorge, the find is almost unanimously praised. Everything is good to lose with grams of weights and liters of gasoline. Whether it’s small engines (1.4 TSI of the Volkswagen Group) or large emotional blocks, downsizing policies regularly opened, in recent years, many solutions to reduce consumption. This is not new: optimized to better better direct injection, Stop & Start, energy recovery braking, walkout of some devices (air-con, oil pump compressor) at least seeking phases, etc. Now, the trend is another magic formula, brought as evidence: as disable a portion of the cylinder when conduct does not use the power and the torque of the engine. Well, On paper it’s simple.
The system is not yesterday, yet: the Mercedes class S W220 (1998-2003) and the same generation CL had already opened a similar device on the V8 and V12 of the 500 and 600. Fairly quickly abandoned for questions of reliability.
The principle reappeared later. On the V8 Chrysler 300 c for example, or on the Ferrari California and recently, for the Twin 4L Audi V8, introduced on the S6/S7/ S8. And also on the Bentley Continental GT as an entry-level, also. In fact, the system is imperceptible. Turning with 4 of the 8 cylinders powered, it plays speed stabilized with the same mechanical approval, the complete block road rehabilitation intervening instantly as soon as a stimulus required (to see, test: Bentley Continental GTC V8 507 ch).
This is that another brand of the Volkswagen Group is going to adopt the Cylinder technology on demand. Lamborghini, according to internal information obtained by some of our colleagues whose Auto Motor and Sport (Swedish edition), reserve this novelty for the V12 of the Lamborghini Aventador as early as the end of the year. From the Paris Motor Show, the large block 6.5L of 700 HP turn on 6-cylinder (paradoxical, with a LP700-4?) quiet driving and resume 180 milliseconds (against 230 milliseconds on the Ferrari V8). In Lamborghini, believed that the race to efficiency going on primarily by the decrease in weight. Not only visibly. The consumer would thus lowered to 16L/100 km, against 17.2L/100 km in combined cycle currently.
In fact, the idea is admissible. Remains to be defined, ultimately, what will be the impact on the longevity of addition of electronic and mechanical constraints logically implied by the system, let alone on an advanced engine. Restore a few milliseconds of the half of the cylinders of an engine supply, already turning, it appears almost banal today. Who knows, the skepticism lose perhaps with hindsight.
