Tire pressure measurement units include kg/cm2, bar, Kpa, Psi, and atmospheric pressure. The conversion relationships are as follows: 1kg/cm2=0.98bar=98.0665Kpa=14.2Psi, and 1 atmospheric pressure=1.03327kg/cm2. Additional information is provided below: 1. Excessive tire pressure reduces tire friction and adhesion, affecting braking performance. 2. Excessive tire pressure causes steering wheel vibration and deviation, reducing driving comfort. 3. Excessive tire pressure accelerates wear on the central tread pattern, shortening tire lifespan. 4. Increased body vibration indirectly affects the lifespan of other components. 5. Overstretching of tire cords leads to reduced elasticity, increasing the load on the vehicle during driving.

The Real Reputation of Honda CRV Hybrid

Honda CRV Hybrid has a good reputation and offers great value for money. Here are the specific details: 1. Introduction to Honda CRV: The pricing of the CRV Hybrid model is very fair this time, without using the National VI emission standards to raise prices. It is priced the same as the corresponding National V models, with identical configurations. The CRV Sharp-Hybrid series is equipped with a 2.0L engine, delivering a maximum power of 146 horsepower, while the electric motor's power is equivalent to 184 horsepower. 2. Honda CRV Configuration: The Honda CRV Hybrid version is powered by a 2.0L naturally aspirated engine, so there's no need to worry about oil dilution issues. The i-MMD hybrid system relies more on the electric motor for driving. When the battery pack is sufficiently charged, the vehicle can accelerate purely on electric power.

What are the pros and cons of the BYD Song Plus DM-i?

Here are the pros and cons of the BYD Song Plus DM-i as follows: (1) Pros: 1. The acceleration is very linear with good speed increase, and no sense of jerkiness is felt; 2. The seats are relatively soft with good comfort; 3. The overall interior feels decent and doesn’t appear cheap; 4. The rear seating space is very large with a completely flat floor; 5. Comes with built-in car karaoke and external discharge functions; 6. Front double-layer glass provides excellent noise insulation, and the engine is completely silent. (2) Cons: 1. The chassis suspension tuning is average, which might be the reason for the recently widespread online reports of rear seat resonance; 2. The rear noise insulation is much worse compared to the front, mainly in terms of wind noise and tire noise, possibly related to the use of Giti tires; 3. The trunk space is not large enough, which is not friendly for friends who frequently go on road trips; 4. No spare tire; 5. The price is relatively high.
