What does GAC Toyota gr mean

GR is the abbreviation of "GAZOO Racing". At present, Toyota has launched a total of 12 models. Among them, GR YARiS is a high-performance version of YARiS (in China, it is GAC Toyota Zhixuan, but it has been lengthened).

And GR refers to the sports car specially developed by Toyota. In addition to GR YARiS, there is also GR Supra, which has attracted much attention. Well, the GR Supra model bought by Che Rujun has just arrived... "Horse Demon King" or "Bull Demon King"? After many years, Supra finally returned to the public eye with the help of BMW.

First of all, the GR series is a typical V-shaped six-cylinder layout., each cylinder has four valve designs. According to the consistent distinction of Toyota engines, the FE layout belongs to the narrow-angle intake and exhaust valve clamping design, which is a design that focuses on fuel economy. With the micro-scale of the 2ZZ-GE engine, the FE layout also has a trend of a unified car factory.

About its performance cars, Toyota has two brands, one is GR and the other is TRD. GR is a team operated by Toyota's wholly-owned racing subsidiary. TRD is a wholly-owned subsidiary of Toyota for special vehicle modification, both of which are Toyota's own sons.

Toyota is a racing-level horizontal car. The _R brand was originally launched by Akio Toyoda before he became the president of the company. Now it has become a special racing department of the company, and at the same time, it develops performance-oriented mass-produced cars for Toyota.

What are the beginnings of GR SUPRA and GR YARiS? GR SUPRA, also known as the new generation SUPRA, is a model jointly developed by Toyota and BMW (actually dominated by BMW). It adopts the same chassis platform, rear-wheel drive layout, B48/B58 series engine and ZF 8-speed manual automatic transmission as the current BMW Z4.

What spark is the best for the 2zz engine

The brands with better spark plugs are Bosch, NGK, Denso, Suzuki, 3D, McKun, Coolster, Honeywell, Autotley, etc. Spark plug composition: The spark plug is mainly composed of wiring nut, insulator, wiring screw, central electrode, side electrode and shell, and the side electrode is welded to the shell.

Iridium gold: Iridium gold spark plugs can make the electrode much smaller than ordinary spark plugs due to the high strength of the arc, high temperature, fast response speed, and not easy to accumulate carbon.

Iridium spark plugs are the best, and their performance is also the best. Iridium material has the characteristics of high hardness, high corrosion resistance and high melting point, and its spark plug performance is the best.Iridium is the most corrosion-resistant and wear-resistant precious metal, which can not only meet the needs of high-power engines, but also withstand high temperature conditions, so that the electrode is not easy to melt and damage.

The following three brands of spark plugs are the best: Bosch Bosch Germany is one of the products of the world's top 500 auto parts manufacturers, mainly used for German series models. However, due to the lack of Bosch products and insufficient concentration, the quality of the spark plugs manufactured by Bosch in China is uneven.

Summary Motorcycle spark plugs are the key parts that determine engine performance and service life. Choosing a good spark plug can improve the power performance and fuel economy of the motorcycle, thus bringing a better driving experience.

Platinum spark plug The biggest feature of platinum spark plug is long life, good durability, stable spark, and suitable for poor conditions. Its life cycle is about 40,000 kilometers.

Corolla engine parameters

1. Main parameters of performance: hybrid model, four-cylinder engine to high-power 99 horsepower (73kw, 5200rpm), maximum torque speed 142N·m (4000 Rpm), engine compression ratio 11.

2. According to the fuel usage of the engine, the engine can be divided into two types, one is a gasoline engine and the other is a diesel engine. The volume of the gasoline engine is relatively small, the mass is light, and the noise is relatively small. The diesel engine is relatively large, the power is strong, the economic performance is good, and the noise is relatively large. .

3. Year of installation: 2019 model. Model: Leiling Shuangqing Performance parameters: hybrid model, fourThe maximum power of the cylinder engine is 99 horsepower (73kw, 5200rpm), the maximum torque is 142N·m (4000rpm), and the compression ratio is 11.

4. Corolla uses two engines in total, one is a 2-liter turbocharged engine and the other is an 8-liter naturally aspirated engine. The 2-liter turbocharged engine has a maximum torque of 185 Nm. The maximum power speed of this engine is 5200 to 5600 rpm, and the maximum torque speed is 1500 to 4000 rpm.

5. [Pacific Automobile Network] The 21 Corolla is equipped with two different types of engines, a 5-liter three-cylinder and a 2T four-cylinder. The maximum horsepower of the 5-liter engine is 121PS, and the peak torque is 148nm; the maximum horsepower of the 2T engine is 116PS, the peak torque is 185nm, and the two engines are matched with CVT stepless transmission.

Why are the current joint venture engines not as good as domestic ones?

1. It is definitely impossible. It's not that the engine technology is not good, but that the control dimension of the whole vehicle is not good. This is the biggest difference between domestic cars and joint venture cars.

2. This is also the reason why many independent brands are still using imitation engines, because the imitation cost is relatively low. It is true that your own brand engine lacks power and high fuel consumption, but that's a thing of the past. Nowadays, most of the independent brand engines have good power, and most brands have entered the stage of independent research and development and production.

3. Generally speaking, the production technology of domestic engines is relatively general, and the development time is relatively short;The technology of joint venture engines is relatively advanced and takes a long time to develop. However, with the progress of China's car-making technology and strength, many famous engines have also appeared in China.

4. If we compare the latest domestic engines with the world's mainstream engines, there are gaps in performance, thermal efficiency and technology, but domestic brands have also achieved results in their exploration in recent years.

5. Engine: As the core assembly of the vehicle, the quality of the domestic engine has been greatly improved. For example, the third-generation engine independently developed by Chery has a thermal efficiency of up to 31%, which has a relatively high thermal efficiency in domestic cars and even some joint venture cars.

Take stock of the top ten engines in Toyota's history!Which one have you ever owned?
