GOL is equipped with advanced EA827 1.6L water-cooled straight-four four-stroke gasoline engine of excellent quality and reliable performance.

¨ Major technical characteristics of the engine
GOL adopts 1.6L straight-four engine with multi-point electrically controlled fuel injection, overhead camshaft and has created a new power source for economy family cars.
Strong power performance
As a model of new generation economy family car, the power of GOL can compete with any other automobiles. The maximum power can be 64KW/5200r/min and under the engine speed of 3000r/min, the powerful torsion of GOL achieves a peak output of 128 N/M. The start acceleration is so quick that it takes only 13.2s to reach 100km/h after start. The maximum speed exceeds 171km/h.
Environment friendly
GOL adopts three-way system and the precious and heavy metal content is as high as 80g/ft3, therefore, exhaust of the car can easily meet the NO.2 Europe emission standard. High efficient fuel recovering device and effective control of fuel evaporation exhaust further reduce pollution to the environment and green environmental protection is ensured.
High economic efficiency
As an economy car, GOL is by no mean inferior in terms of oil economy. Oil consumption is ≤4.9L/100km at constant speed of 60km/h, ≤6.1L/100km at 90km/h and ≤8.0L/100km at 120km/h. Taking high efficiency and high performance into account at the same time, the excellent oil economy makes driving free from worry.
Advanced control performance
GOL adopts a multi-point oil injection system. The ECU (electronic control unit) is something like a commander and the injection nozzle, λ sensor, knock sensor, manifold air temperature and pressure sensors are the “ears and eyes” dispatched by the commander to the battle fields. The “ears and eyes” get “information” like a spy in various operation conditions and send the information to ECU, the commander, which determines the operation condition of the engine based on the reflected information, calculates the volume of oil and controls the injection nozzle, making the operation of the engine in every operation condition within the best and most rational scope for both great power and ideal economy. At the same time, the emission requirements can be met.

GOL adopts a synchronous 013 five forward-gear manual transmission with two axles and integral differential mechanism. The gear I and II are double-cone synchronizer and gear III, IV and V are single cone synchronizer. It is very easy to change the gears. The case is made of magnesium alloy for lighter weight and good strength.

Major design characteristics of 013 five-gear manual transmission are as follows:
1. The major decelerator, the differential mechanism and the gearbox are combined for more compact structure of the whole car.

2. Synchronizer structure is adopted for all the five forward gears for easy gear change and eliminates noise when changing the gears.

3. Cloudburst treatment is adopted for gears of the major decelerator to increase surface load bearing capacity. Grinding and matching technology is adopted for better gear surface quality. Advanced processing technology such as grinding processing technology is adopted for gears of the gearbox to improve processing accuracy for smoother high-speed operation and lower noise of the gearbox.

4. Every gearbox is carefully tested and adjusted during assembly for best clearance between the gears. Automatic compensating plate is adopted at the back end of the output shaft, which will automatically adjust the clearance of the main drive gear according to the temperature of the gearbox to keep the clearance unchanged whether it is under high temperature or low temperature. Thus, the service life of the gearbox is improved greatly and the noise transmitted by the gears is reduced.

5. Positive gearing of straight gear is adopted for the backward gear, making the structure of the gearbox more compact and reliable.

6. Interlock and self-lock devices are adopted for gearshift to make gear shift of the gearbox more accurate and reliable and avoid malfunction of gear shift.

7. The same service life as the complete car is designed for the gearbox and it is maintenance free. It is unnecessary to replace the gear oil. Multi-grade gear oil is used to meet the demands in winter and summer as well as in harsh climate.

8. The transmission ratio carefully matched and calculated can meet the requirement of the car performance. Using the fifth gear when driving at a high speed saves oil.
