Comparison between BYD Tang and Equinox?

Comparison between BYD Tang and Equinox includes: 1. Power: The BYD Tang is equipped with a 2.0TI engine independently developed by BYD, with the model number BYD487ZQA; the Equinox is equipped with a 1.5T turbocharged gasoline engine. 2. Configuration: The BYD Tang features an ADAS intelligent assistance system and vehicle stability control system; the Equinox comes with a panoramic sunroof and an electric tailgate that can be opened in two ways. 3. Interior differences: The BYD Tang's center console is equipped with a 12.8-inch oversized floating LCD screen that supports voice control. This screen can also rotate 90 degrees, and the center console area eliminates physical button designs, integrating all functions into the screen; the Equinox is equipped with an 8-inch LCD display, with the central air vents featuring more chrome decorations, and the panel design in front of the passenger seat is more three-dimensional.

What details should you pay attention to when picking up a new car?

Details to pay attention to when picking up a new car: 1. Check the odometer: Generally, a new car's odometer reading between 0-30km is normal, as new vehicles undergo testing after production and may be moved during transportation by dealers. 2. Check the nameplate: The door frame of the car has a nameplate with production date, engine number, etc., which serves as the car's ID. 3. Inspect the exterior: If you can choose among several cars of the same color and model, pay attention to body gaps and paintwork. One technique is to focus on the gaps between the bumper and body, door gaps, and front/rear bumper gaps. Open the doors to check for any color difference between the interior and exterior paint. 4. Examine the engine: The engine is crucial. A well-functioning engine should have no oil leaks, respond quickly and sensitively when started, run smoothly without shaking, and produce even sounds without sharp or irregular noises. Place your hand on the engine cover—there should be no noticeable vibration. Inside the car, you should barely hear the engine noise. Such an engine is normal and qualified. 5. Check tires and doors: Normal new tires should have no damage on the sidewalls, especially the front tires. The tread should have no puncture marks, and the tire hairs should ideally be intact, at least visible. For doors, check the opening force and resistance, as well as the condition of the windows to ensure they are not loose or leave gaps when closed. 6. Inspect interior and exterior lights: Turn on all lights, including hazard lights. Check interior lighting inside the car, then step out to verify if headlights, turn signals, and brake lights are functioning properly. Faulty lights can severely impact driving safety at night.

When to Drive a New Car at High Speed?

It is recommended after driving 5,000 kilometers. During the break-in period of a new car, high-speed driving above 90 km/h should be avoided. When the new car has been driven for about 5,000 kilometers and is about to complete the break-in period, the owner can briefly run the engine above 4,000 RPM to reduce carbon deposits and improve engine performance. Here are some precautions: 1. Avoid full-load driving: New cars during the break-in period should avoid full-load driving, as excessive load increases the burden on the engine and transmission, leading to excessive power output and over-wearing of components. Therefore, owners should understand the maximum load capacity of their cars and avoid full-load driving during the break-in period to extend the vehicle's lifespan. 2. Avoid prolonged use of low gears: Owners should avoid prolonged use of low gears and intentionally allow each gear to undergo the break-in process. For automatic transmission models, although the manual gear shifting process is eliminated, owners should accelerate continuously under good road conditions to allow the transmission to shift up smoothly and avoid insufficient break-in of higher gears.

Can a car that uses 95-octane gasoline be filled with 92-octane gasoline?

A car that uses 95-octane gasoline can occasionally be filled with 92-octane gasoline. If you occasionally fill up with the wrong gasoline octane rating, simply switch back to the correct octane rating after use. However, long-term use of the wrong octane rating can have the following effects: For vehicles recommended for lower octane ratings, accidentally using higher octane gasoline will not cause damage. However, the increase in octane number will alter the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in a noticeable drop in performance. For vehicles recommended for higher octane ratings, using lower octane gasoline can cause engine knocking. Because the octane number is significantly lower, the gasoline's ignition point decreases, causing it to ignite prematurely during the compression stroke. If the fuel ignites before the spark plug fires during the compression stroke, resistance will occur during the upward stroke. This resistance makes the engine run very unevenly. If the knocking is imperceptible, it may only increase noise without obvious damage to the engine. However, if noticeable knocking occurs, it indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring. In addition to checking the recommended gasoline octane rating in the car's manual, it is also indicated on the fuel tank cap. Typically, the appropriate octane rating can also be determined based on the engine's compression ratio. Cars with a compression ratio between 8.6-9.9 should use 92-octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95-octane gasoline. If the compression ratio is higher, 98-octane gasoline is recommended. However, with the use of new technologies, the octane rating cannot be solely determined by the compression ratio. Engines with high compression ratios can also be tuned to use lower octane gasoline because factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline octane rating, the higher the octane number and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane.

What Do the Numbers on Car Tires Mean?

The slash / is only used to separate the front and rear numbers, and the number behind it represents the aspect ratio. The following are measures for car tire maintenance: 1. Reasonable selection and matching of tires: Do not mix tires of different specifications and brands on the same vehicle or axle. At the very least, the same specification, brand, tread pattern, and even the same manufacturer's tires should be used on the same axle. 2. Inspection of tire surface wear: The tire surface wear condition should be frequently observed, and any issues should be addressed promptly. Generally, tires have wear indicators, and once the wear limit is reached, they must be replaced. Regularly check the tire tread and sidewalls for cracks, cuts, or other damages.

Is the vehicle still under warranty if not serviced at a 4S shop?

Maintenance not performed at a 4S shop does not void the vehicle's warranty. Below are relevant details:1. Documentation: The key is to choose a qualified auto repair shop and retain maintenance records. During the warranty period, owners can freely choose maintenance locations, provided servicing is conducted at certified repair facilities with proper documentation retained. Should issues arise, these records serve as proof for warranty claims.2. Warranty Duration: New vehicles typically have a warranty of two years or 60,000 kilometers, whichever comes first. This means warranty coverage is subject to two conditions—a time limit of 2 years and a mileage limit of 60,000 km. Upon reaching either threshold, the vehicle's warranty period expires.
