If we must remember that a kiss is just a kiss, then it seems doubly likely that a grin is just a grin. Not long ago Motoring said it believed Ford was working on a Fiesta RS ; when the mag asked Ford Performance Europe boss Leo Roeks if he planned something hotter than the Fiesta ST , Roeks put on "a broad grin" and said, "I can't tell you, but I'm very busy." Turns out that grin meant nothing, at least according to Ford of Europe design director Amko Leenarts. He told Dutch publication AutoRAI , "The performance of the new Fiesta ST is already such a high level that a more powerful model is not necessary." While Leenarts believes the Fiesta ST doesn't need any more performance juice beyond its 197 horsepower, the competition takes a different view. At the beginning of the year, Volkswagen suggested its 197-hp Polo GTI chassis leaves potential performance on the table, so a harder, more powerful Polo wo...
When it comes to your car’s exhaust system, the catalytic converter (often called the "catalyst") plays a crucial role in reducing harmful emissions. However, when it fails, it can lead to performance issues and even legal problems. In this blog post, we’ll explore **how a catalytic converter works** and **what happens when it goes bad**. What Does a Catalytic Converter Do? The catalytic converter is an essential part of your car’s exhaust system. Its main job is to **convert harmful pollutants into less harmful gases** before they exit the tailpipe. Here’s how it works: 1. Reduces Harmful Emissions The catalyst contains precious metals like platinum, palladium, and rhodium,which facilitate chemical reactions that break down pollutants: - Carbon monoxide (CO)→ Converted into carbon dioxide (CO₂) - Hydrocarbons (HC)→ Converted into water (H₂O) and CO₂ - Nitrogen oxides (NOx) → Broken down into nitrogen (N₂) and oxygen (O₂)* 2. Helps M...
