General Lee: For such a TSP platform, indeed, is the test of the ability to integrate the same time, just She always has been mentioned in the business platform is a completely independent intellectual property platform and our platform is t In the shape of the design, the Core wing broke through the traditional appearance of the other models, the Core-wing sense of movement and high-level sense of the high degree of balance, which must be improved, both in the interior styling
As the Audi S series models Fielding of engine, its inevitable have proud of the dynamic data, this is 90 ° Angle of 4.0-liter V8 engine with high and low power TFSI two different versions of the adjustments: in the Audi 'S6' (including travel edition), S7 cars drove is low power version, with 420 horsepower (309 mw) of the most high power and 550 cattle · m of the maximum torque, and S8 models of carrying high power output version 520 horsepower (382 mw), torque to a 650 cattle · m, easily overtake the generation on the use of 5.2 liters v10s naturally aspirated engines S8 models, and, of course, more than a new generation of W12 cars natural isn't. The engine to use silicon alloy casting block, because the ascension of silicon content and improve the cylinder walls wear resistance level, extremely compact layout make its length of only 497 mm, can just placed in the front axle above, better optimized the rear axle load distribution before.This "cylinder on demand system" can be understood as on-demand cylinder management system, as the name suggests, is a set of vehicle dynamic demand on (engine load) judgment, to the engine of the working condition of the corresponding adjustment system. In the means of realization, the cylinder on demand system "with other manufacturers also very much the same method, and its realization is depend on an upgrade of the Audi variable valve lift control system-" AVS", in the camshaft increased a set of "zero lift" of the CAM and realize. When the switch to the "zero lift" CAM, camshaft will not drive valve movement, 2, 3, 5, 8 four cylinder of the exhaust port and is in the closed position. (Audi V8 cylinder Numbers different from any conventional "left 1357 right 2468", but the left, right, shut down 1234 5678 2358 cylinder, the engine is equivalent to a V4 engine.)And this one TFSI 4.0 of the terrible lies in that it is the first vehicle emissions of variable turbo engine! You can imagine it's exhaust layout to how complex and entanglements. In the state of cylinder discontinuation, ECU can load and engine condition according to the output power in the state of the V8 25-40% change between flexible, in other car DVD player words is torque output can be in 120 cattle · m-250 cattle · m changes between.To achieve closed cylinder operation, need to meet the following the operation condition of the engine many condition: the first is the speed of the engine than idle speed, in 960 ~ 3500 RPM between, engine output torque in peak torque of 25% ~ 40% and, secondly, the temperature of cooling fluid than 30 , and transmission shift in 3 to block above. And the gearbox "sports model" will not affect "cylinder on demand" systems work.In the succession of the new "S" series Audi cars will all carry "start-stop" intelligent rev. Stop system, further improve product performance of the economy, it helps to reduce carbon dioxide emissions Audi products up to 24 g/km. "Cylinder on demand" and intelligent rev. Stop joint action to make the engine efficiency increased by 12%, the average fuel consumption could reach 10 liters / 100 km or even lower.In addition to variable displacement of cylinder outside management technology, this one new 4.0 TFSI double turbo engine technology still has many bright spots, such as the active engine mount system-further reduce vibration of the carriage, ascension comfort; Reduce the piston resistance of diamond-like carbon coating, DLC more efficient engine thermal management system, and so on, the car Audio system can the B&O realize the function of the car DVD ANC active noise reduction (through the sound waves superposition interference eliminate noise), make this a double turbocharged V8 engine in the smooth, economy and dynamic performance can take out the superior performance.
