What is an STI car?

STI is not a car brand. To be precise, STI is an organization under Fuji Heavy Industries' Subaru automobile company, namely the Subaru Sports Modification Department. Generally, the models modified by this department are collectively referred to as STI, representing high-performance versions of civilian vehicles. Below is relevant information: 1. Usually, when people refer to STI, they mean the Impreza. Back then, Subaru used modified Imprezas to replace the older Legacy models to enhance competitiveness in the WRC, subsequently becoming strong contenders for championships in WRC events. The most famous and regarded as a modification classic among Impreza STIs is the 1998 22B, Subaru's only two-door sedan. 2. STI is affiliated with Fuji Heavy Industries Ltd. in Japan, and its role is to support Subaru's participation in global motorsport events. Among these, the World Rally Championship (WRC) is STI's main stage. The competition-spec engines for Subaru WRX are all assembled and tuned by STI before being shipped to Subaru's racing headquarters in the UK.

What is the difference between S gear and D gear?

d gear and s gear difference is: 1. S gear is more responsive than D gear. After shifting into S gear, the upshift will be slightly delayed. During driving, if you suddenly press the accelerator, S gear will react quickly, but D gear will take a little longer to respond. When pressing the accelerator, S gear provides a very direct driving feel, while D gear is relatively more gentle. 2. S gear consumes more fuel than D gear. While pursuing speed advantages, S gear also increases power output. Long-term use of S gear will naturally result in higher fuel consumption than D gear due to increased air intake. However, you won't experience the driving pleasure of S gear in D gear mode. 3. S gear is more powerful when climbing slopes. When climbing a slope, if you don't switch to S gear, you may notice some abnormal noises from the car's engine. This occurs because the engine cannot provide sufficient power at low RPMs, so it's advisable to use S gear when climbing slopes.

What is the highway fuel consumption of the Citroen C-Quatre?

The Citroen C-Quatre 2.0 has an average highway fuel consumption of 8L per 100 kilometers, which is generally considered fuel-efficient. However, actual fuel consumption is influenced by various factors, so specific fuel usage should be based on actual driving conditions. The main factors affecting fuel consumption include the following situations: 1. Prolonged idling without turning off the engine or frequent ignition. When waiting for extended periods without needing to move the vehicle, it is recommended that the owner turn off the engine. 2. Maintaining a reasonable driving speed. Each car has its own economical speed, at which fuel consumption is the lowest. However, the economical speed for most SUV vehicles is not very high, typically ranging between 65 to 90 km/h. To reduce fuel consumption, drivers should try to maintain their speed within this range. 3. Avoid sudden acceleration and deceleration while driving. Strive to maintain a steady speed and avoid sudden acceleration and deceleration. Do not press the accelerator pedal hard to accelerate, as this will significantly increase fuel consumption. This is commonly seen in daily driving, especially in heavy traffic, at red lights, or when changing lanes.

How long does it take to get the license plate number?

License plates can be produced within fifteen business days, and vehicle owners can collect them independently. Vehicle license plates must be installed. During this period, temporary license plates will be issued by the authorities, and the previously received temporary plates will expire. The temporary plates must be replaced with the official vehicle license plates. License plates must be displayed within three months after purchasing the vehicle, and temporary plates can be used before that. Below is the procedure related to vehicle license plates: 1. Pay the vehicle purchase tax and submit the required documents (copy of the invoice, ID card or organization code certificate, copy of the vehicle qualification certificate, first copy of the purchase order, and tax payment form). The first series of the receipt and the original vehicle qualification certificate must be carried. 2. Obtain the registration application form and external inspection form. 3. Fill out the registration application form, and take the qualification certificate and application form to the environmental protection office to stamp the environmental protection seal. 4. Take photos, scan the code, and print the vehicle parameter table. The original qualification certificate must be marked with "on the inspection line."

Why does flashing the program improve power?

After flashing the program, the reason for the power improvement is: the turbo pressure of the turbocharged engine increases, the fuel injection volume increases, and more air and gasoline enter the combustion chamber to do work, thus improving the power. The following is the relevant information about flashing the program: 1. Flashing the program for a car means updating the program in the ECU car computer to meet performance requirements, including increasing power or saving fuel, or even adding new functions. Flashing the first stage of a car refers to keeping the hardware unchanged and improving power by changing the ECU software parameters. 2. After flashing the program, fuel consumption will also increase. Because the increase in power requires more air and gasoline to participate in combustion, resulting in increased fuel consumption.

How to Shift a Serpentine Gear

Shifting a serpentine gear is not much different from shifting a straight-line gear. The shifting method for a serpentine gear is as follows: 1. For turning off the engine and long-term parking, shift to "P" gear and engage the handbrake. 2. For moving forward, shift to "D" gear. For safety, you should press the brake when shifting to "D" gear, and then slowly release the brake after shifting. At this time, due to the power output, the car will move forward slowly even without pressing the accelerator. Some cars have D3, D2, D1, L, or S gears after "D" gear, the principle of which is to limit the automatic transmission from shifting to higher gears. 3. When the speed and RPM are not high, you can switch between "D" and "D3" gears without stopping the car. 4. For reversing, shift to "R" gear. Similarly, you should press the brake to shift, and switching between "D" and "R" should only be done when the car is completely stopped to avoid damaging the transmission. 5. For neutral and short-term parking, shift to "N" gear. "N" is only a transition between "D" and "R". For example, when waiting at a red light, parking for less than half a minute does not require shifting to "N" gear; just stay in "D" gear and press the brake. For parking for one or two minutes, shift to "N" gear and engage the handbrake. For parking for four or five minutes or longer, shift to "P" gear and turn off the engine.
