As the saying goes: look with a midsize sedan, limousine see technology becoming more mature in the eyes of consumers of domestic high-class cars, real materials the use of technology is the benchmark for judging an advanced car, see "Technology" The key is to look at the car's "Big Three", that is, engine, chassis and gearbox, which is equivalent to three parts of the human heart, bones and nervous system, determine the real strength of a limousine.
A
Engine: V6 "temptation"
A good car, whether driving or riding, the most direct experience of the power comes from the engine. Said engine as a "heart of the car" more appropriate, vehicle power, economy, environmental protection is accomplished by it.
L4 and V6
Under normal circumstances, according to the size of the different engine displacement divided into three-cylinder, four-cylinder, six-, eight-cylinder types, and L4 (inline four-cylinder engine) and V6 (V-type six-cylinder engines) are more common. Currently, most of the domestic high-class cars are equipped with the main level L4, 2.8 or 3.0 only in their displacement was on the highest level with a V6 engine, while the sounds of nature, the crown, the Audi is more than its 2.3 displacement at all levels All vehicles equipped with V6. L4 engine has the advantage of low cost, cheap, but in terms of dynamic aspects, or from the comfort of smooth and quiet performance, and fuel consumption under the same displacement, a grade worse than the V6 a whole.
First, V6 engine for the car provides a powerful "heart" to provide high-end car owners need power. Compared to L4, V6 looks just added a two-cylinder, but it provides ample power is the same displacement of L4 far can not match.
V6 engine is smooth and quiet Another feature is the user for another intimate luxury car design. Compared to L4, the former not only to achieve mechanical equilibrium in the first-order (cylinder number is a multiple of 2), but also can achieve second-order balance (cylinder number is a multiple of 3), so running the most stable, minimal vibration, while the engine is running noise properties. The L4 will hear often in hard acceleration when the hoarse roar of the engine, causing the body shake people feel discomfort.
Love V6 luxury cars
It is noteworthy that, using the V6 engine models generally low speed high torque can be achieved, so that when the car is running at low speed for greater traction. Driven a car people who have come to realize: just start the car, or a low speed acceleration is most needed to provide traction to drag the rest of the body. Sounds of nature such as VQ-series V6 engine cars per minute at 3600 rpm and 318 Newton meters will be able to demonstrate high-torque, and torque output is basically no more than 270-320 range, very smooth. The general speed of the engine in this 200 Newton meters only, while the torque output of the range should be more than 70. Currently, 1.3L-2.3L displacement of the intermediate or high-class cars they use inline four-cylinder engine, while the 2.3L displacement of more than commonly used multi-cylinder design, power, stability, comfort and all have a guarantee, which BMW inline six-cylinder, but also the Audi V-type six-cylinder, V6 engine can be said is a sign of luxury cars.
V6-leading technology to help force
Is also a V6 engine, both in the design, manufacture, process or in the performance or different. It is worth mentioning that only in the domestic car Teana and Audi A6L has won the world's top ten of the most advanced engines to China. In particular, the sounds of nature of the VQ series V6 engine, the only world for twelve years was selected as one of the top ten engines, torque and horsepower in the area are extremely superior, can match only with a 3.2-liter BMW inline 6-cylinder engine. Its simple structure makes work more efficient, shorter throttle response, so it not only in time of need can be abundant in an instant burst of power, when running at low speed can produce a greater torque. In contrast, the recently listed some of the Japanese cars, with its 2.0-liter and 2.4 liter two engines are only 16-valve inline 4-cylinder VVT-i engine, strictly speaking, can only count a generation products, regardless of is the torque and power performance V6 engine there is not a small gap.
