Having driven for many years, the gear division of automatic transmissions is actually quite intuitive, with positions like P, R, N, and D. P (Park) is used to park and secure the car, preventing it from rolling away; R (Reverse) is for backing up, and it's best to stop by braking before shifting into it; N (Neutral) allows the car to roll freely; D (Drive) is the driving gear, used for automatic shifting while driving. This division enhances driving safety and prevents accidents caused by novice mistakes. For example, in city traffic jams, simply leave it in D; when going up or down hills or towing, using L (Low) gear can save brake pads. I've always found this design quite user-friendly, not only simplifying operations but also protecting the transmission's lifespan—just remember never to leave it in N when parked, as it accelerates wear. Nowadays, some new models add a sport mode, but the core gear setup remains unchanged.

How many cylinders does the Buick Excelle 1.3T engine have?

The new Excelle is equipped with a new generation of 1.3T/1.0T Ecotec dual-injection turbocharged three-cylinder engine, which offers low fuel consumption and excellent performance. Below are some details about the new Excelle: 1. The interior of the new Excelle retains the 360-degree wraparound design and floating layered elements from the previous model, enhancing the sense of security. The cabin features soft-touch materials with a natural feel, combined with piano black lacquer, creating a refined overall ambiance. Double stitching and leather piping highlight the elegant details. Thanks to the short front overhang design, the 2018 new Excelle offers spacious and comfortable seating, with rear air vents—a rare feature in its class—providing a more comfortable ride for rear passengers. 2. The newly designed family-style front grille with wing-shaped elements gives the new Excelle a more sporty and dynamic appearance. However, the sporty feel isn’t just limited to the front; the new Excelle also features shorter front and rear overhangs, further emphasizing its athletic character. Except for the two base 1.0T models, all other variants come with 16-inch dual five-spoke alloy wheels.

What are the impacts of not transferring insurance after selling a car?

The impacts of not transferring insurance after selling a car are as follows: 1. No traffic accident occurs: After the vehicle is sold, the insurance period is only one year, and it must be repurchased upon expiration. If no insurance incident occurs during this period, there is basically no impact when purchasing insurance yourself after it expires. 2. A traffic accident occurs: Regulations stipulate that commercial insurance must be transferred. The motor vehicle insurance clauses stipulate that during the insurance period, if the insured vehicle is sold, transferred, gifted to others, or its purpose is changed, the insured must notify the insurance company in writing and apply for endorsement. Otherwise, the insurance company has the right to refuse compensation. 3. Insurance company claims: As long as the accident is not caused by illegal driving, the insurance company can still settle the claim within the scope of liability. The trouble is that the insurance company stipulates that the compensation must be paid to the insured, which means the insured's ID card and bank card must be provided. 4. Insurance company refuses to settle the claim: The most important thing is that once personal injury, death, or disability occurs, the consequences of the accident are serious, and huge compensation is required. If the new owner is unable to compensate, the original owner will bear joint liability.

What does 'liter' mean in Audi cars?

Audi cars display 'liter' to indicate fuel consumption per hour. As a fuel economy indicator for vehicles traveling at constant speed on good road surfaces, this measurement is widely adopted because constant-speed driving is a fundamental operating condition for cars on highways, and such fuel consumption is easy to measure. Specific details are as follows: 1. Reduce vehicle weight: Lowering vehicle weight is directly proportional to fuel consumption. It is said that for every 10% reduction in vehicle weight, fuel consumption will decrease by a corresponding percentage. 2. Improve car aerodynamics: Enhancing the vehicle's shape to reduce air resistance will significantly lower fuel consumption, as these two factors are also directly proportional.
