To identify the type of engine your car has, you can start by checking the vehicle's owner's manual, which typically lists engine specifications. Another reliable method is to look for the Vehicle Identification Number (VIN), often found on the dashboard near the windshield or inside the driver's side door. The 8th character of the VIN usually indicates the engine type. You can decode the VIN using online tools or by consulting a dealer. Additionally, most engines have an identification tag or engraving on the engine block that states the engine model. For more precise details like engine size, configuration, and power output, manufacturer websites or contacting authorized dealerships are useful resources. Always ensure to gather information from official and reputable sources for accuracy.

No, electric vehicles (EVs) are generally better for the environment than traditional gas-powered cars.

1. Emission-free: EVs produce zero tailpipe emissions, reducing the amount of carbon dioxide and other pollutants released into the atmosphere.

2. Energy efficiency: Electric vehicles are 4-5 times more energy efficient than petrol/diesel cars. They convert a higher percentage of the electrical energy from the grid to power at the wheels.

3. Renewable energy integration: If charged from renewable sources like wind or solar power, emissions can be even lower.

4. Decrease dependency on fossil fuels: As electric cars run on electricity, they reduce the dependence on fossil fuels, leading to a decrease in greenhouse gas emissions.

However, there are two main environmental concerns related with EVs:

1. Battery production: Manufacturing the lithium-ion batteries commonly used in EVs can have a substantial environmental impact. The process is energy-intensive and involves the mining of rare earth metals, which can be damaging to local environments.

2. Electricity source: If the electricity used to charge EVs comes from coal-fired power plants, the overall environmental impact is higher, as burning coal for electricity produces large amounts of CO2 emissions.
Overall, the environmental impact of EVs is largely dependent on how the electricity they use is generated. As the energy grid becomes more sustainably focused, the benefits of electric vehicles will increase. Furthermore, innovation is leading to more sustainable battery options which are set to lessen the environmental impact of their production.

Run-flat tyres, designed to maintain vehicle mobility even after a puncture, typically come at a premium compared to standard tyres. Their prices vary based on brand, size, and type but generally range from $150 to $500 per tyre. Factors influencing cost include the tyre's technology level, the vehicle make and model they are intended for, and performance characteristics. For instance, run-flats for high-performance or luxury vehicles tend to be on the higher end of the price spectrum. While more expensive initially, run-flat tyres can offer cost savings in terms of reducing the need for immediate roadside tyre changes or towing. However, they may have a shorter lifespan than regular tyres and can sometimes offer a firmer ride, which are important considerations for potential buyers.
