Since the beginning of these two years, Volkswagen's sales in China are gradually declining, and the aura of German quality seems to have gradually dimmed. According to statistics, domestic sales in 2021 are only 3.3 million vehicles, although it is still the first place, but compared with itself is a decline of 14.1%. Hyundai, Kia, Renault, and Ford have been through a lot of memories in recent years, and Volkswagen understands that in order to re-normalize, it is necessary to launch more products that meet consumer needs.
Minor adjustments to mid-term overhauls
Compared with the current model, the mid-term revamp Sagittarius is mainly adjusted for the forward grille, and the horizontal banner decoration is adopted to make the front face look more fashionable and atmospheric. Dual C-shaped strips make the headlights look even more uplifted, the fog light area features a blackened design, and Sagitar is equipped with full LED lights with IQ.Light technology, as well as flow steering and corner fill configurations.
On the side of the body, the overall silhouette has not changed much, but 18-inch wheels have been added. The tail has not changed much compared to the current model, the tail light style has been slightly changed, the internal structure is more complex and delicate, the exhaust hole of the through-type chrome plating is more exquisite, and many details have been improved to make the appearance of the new Sagitar look much more advanced. At the same time, the body size of the new car has also changed, its length, width and height are 4791mm, 1801mm, 1465mm, the wheelbase is 2731mm, the entire length has increased by 38mm, and the visual effect is more slender.
In terms of interior, it is the highlight of the new Sagitar, using Volkswagen's new semi-suspended interior design language, while having three interior styles to choose from, equipped with a 12-inch touch-type central control screen, and equipped with a Zebra networking system and Travel Assist L2 level intelligent driving assistance system, the sense of grade and technology have been improved a lot.
Highlights of the 1.5TSI evo
The two engines promoted by the Volkswagen brand in China, EA211 and EA888, must be familiar to everyone. As the star engines of Volkswagen's main sales model, these two engines represent the concept of technological innovation of the Volkswagen brand in terms of fuel economy and power performance.
The 1.5TSI evo engine is equipped with a number of advanced technologies, variable section turbine technology (VTG), high compression ratio Miller cycle technology, and the combustion efficiency is increased to 37.5%, which is comparable to honda's 1.5T Earth Dream engine. In addition, there is a high-pressure common rail fuel injection system with a pressure of 350 Bar, APS coating and other technologies, the main cylinder shut-off technology, and the gasoline particulate matter trap, which achieves better fuel economy while reducing emissions.
The maximum power of the 1.5TSI evo engine is 118Kw, the peak torque is 250 Nm, which is 10 horsepower more than the current 1.4T high-power engine, the torque is consistent, and the acceleration performance may not be significantly improved, but the fuel consumption is reduced a lot.
1.5T engine new technical interpretation
From a technical point of view, this new engine uses VTG technology, known as variable-section supercharger technology. This technology mainly alleviates the sticky feeling of the engine at low rotation, increases the air intake of the engine, and greatly improves the response time and acceleration ability at low speed compared with the traditional turbocharger. This kind of turbocharger changes the flow of exhaust gas in the turbine by changing the angle of the blade, adjusts the turbine at low speed, reduces the exhaust gas flow, and increases the turbine at high speed to increase the exhaust gas flow. Doing so reduces exhaust emissions, reduces turbine hysteresis, and increases power smoothness.
ACT evo cylinder passivation, i.e. active cylinder closure technology. This similar technology has been seen on GM's LSY engines. This technology stops working by switching the corresponding cams of the middle two cylinders, the cam becomes a round wheel, and the camshaft rotates without opening the intake valve. In low to medium loads, only two cylinders are powered, greatly reducing fuel consumption.
Miller cycle, a variable compression ratio technology, is achieved by using early valve closing, and closing the valve early before the end of the intake stroke. Compared with the Atkinson cycle, such a method can be more fuel-efficient under low load conditions, with this technology, the Volkswagen 1.5 engine compression ratio reached 12.5:1, even if the displacement is larger than 1.4T, the fuel consumption of this 1.5T engine can be more fuel efficient than the 1.4T engine.
Sagitar's sales in March were 15,148 units, and its cumulative sales in 2022 were 54,099 units, ranking 7th in monthly sales and 4th in annual sales among cars, 2nd in monthly sales and 2nd in annual sales in German cars.
Auto network review: In general, the Volkswagen 1.5T Evo engine was introduced into The country, with stronger power, improved fuel economy and more environmental protection, which are undoubtedly its advantages in replacing the existing 1.4T engine. As a mid-term revamp, Sagitar's high-end model is equipped with a new generation of 1.5TSI evo engine, combined with Sagitar's good reputation as a family A+ class sedan, the future sales will not be too bad.
