The world's top ten engines, also known as Ward's top ten engines, are the list created by the authoritative magazine Ward's Auto World magazine. [1] After testing the models sold in the United States for daily driving conditions, based on the horsepower, torque, technical content of each engine, and the operating characteristics exhibited in actual use, a comprehensive evaluation was conducted, and ten units were finally selected. The best performing engine. The selection list began in 1994 and is released at the end of each year. At the same time, Ward magazine also has the "Top Ten Automotive Interiors" annual list.
The selection process of the world's top ten engines has very clear rules, so it is very authoritative and reference value. The first nominated engines must be mass-produced, and the time when the equipped cars start to be sold is also clearly defined. At the same time, in order to ensure that the top ten engines of the selection can reflect the mainstream trend and are suitable for the majority of the automotive industry, the engines of the participating engines must be sold for less than US$60,000 (in 1995, this standard was US$50,000). Each selection takes about two months, and the selection method is very detailed and special. Instead of using tool testing, all engines are evaluated through daily driving. The important basis for the selection is the engine fuel economy, noise, vibration and impact indicators. In addition, the innovation and power of science and technology, especially the output power per unit mass (specific quality) is also one of the important indicators.
In 2017, the world's top ten engines, the first powerful!
This year's awards are very surprising. This time the V8 engine is not on the list, and in addition to the two six-cylinder engines, the rest are four-cylinder turbochargers and hybrid engines, energy-saving emission reduction is imperative.
Of course, this is not difficult to understand. As the emission requirements of various countries have increased, many manufacturers are becoming more and more active in the development of new energy and turbocharged engines. This trend can be seen from the table.
Let’s take a look at some of the old fairies that are standing still and the new hopes that are rising!
NO.1 BMW 3.0L turbocharged inline six-cylinder engineThe 3.0L turbocharged inline six-cylinder engine team will not be unfamiliar, yes, it won the championship last year. It has a maximum torque of 500N·m on the M240i, which is a very good performance.
The 3.0-liter inline six-cylinder engine codenamed B58 on the BMW 740Li has a maximum power of 326 hp (240 kW) and a maximum torque of 450 Nm. It is also a 3.0 L inline six-cylinder turbocharged engine. The new B58 engine is in dynamic parameters. Compared with the N55, there have been many improvements, especially in terms of torque, which has increased by 50N·m. In addition to the fact that the compression ratio is changed from the original 10.2:1 to 11:1, the design with a longer stroke can not be separated from the reduction of the cylinder bore.
Compared to the N55 engine, the B58 series engine is superior in terms of detail. With its in-line 6-cylinder structure, it is not only smooth but also has amazing power performance. At present, we can appreciate its power in the BMW 740Li. I believe that in the near future, the B58 will be more widely used in BMW models, so stay tuned.
This is the third time that Volanda has won the Ward Top Ten engine, and this time it was ranked second in the top ten engines and the first in the hybrid system.
Volanda's hybrid system is the third time to win the Ward Top Ten engine. GM has upgraded this series of hybrid systems: it guarantees 85km of pure electric range, and the entire powertrain has excellent fuel economy. In the rigorous EPA test cycle, this car The fuel consumption is 2.2L/100km. It can be seen that the spring of the hybrid system has come very violently.
Speaking of Chrysler, some group members may feel strange, but in the United States, this is a small family car, this time the third best engine Chrysler Pacific equipped with 3.6L V6 + dual motor plug-in hybrid system, not only Keeping up with the trend of the times and more flexibly distributing the power of the engine, the Atkinson cycle used in this engine makes it more efficient.
Chrysler Pacific is equipped with a 3.6-liter V6+ dual-motor plug-in hybrid system, an electric motor and a battery pack. It is on the trend of the times and is more flexible in distributing the engine's power. This engine uses the Atkinson fuel cycle. The battery pack has a capacity of 16 kWh. It is reported that the 240V power supply can be fully charged in just 2 hours. Chrysler Pacifica, a new generation of Grand Rapids, is currently available in the US.
