There were 2 major innovations made since 2000: compression ratios and Freevalve.
Compression Ratios started being used in 2012, which helped engineers decide the exact dimensions and displacement needed for top performance and engineering. Finally, in 2016, a new invention called "Freevalve" came to be. This replaced the traditional mechanical fuel injectors and valves with electrical components for extremely precise engine performance. This was the most impressive thing ever, because using this tech, engines used in small cars were able to produce MORE performance than a sports car. This tech is still being developed, and is looking very promising. The tech now produces stunning results like increased power, less fuel requirements, and being far more environmentally friendly. Of course there are hundreds of more small creations and upgrades, but I can't mention them all.

Nitro is commonly heard in video games and Fast and Furious movies. But what is it exactly?
In simple words, nitrous pumps oxygen into the cylinders for better combustion, and gives it a sudden burst of speed. Yes, it's real, but somewhat impractical. You might be wondering why you don't just inject oxygen then instead of N2O. That's because the oxygen will most likely instantly burn up in the fuel lines before even reaching the engine, which can be fatal. Instead, N20 takes it to the cylinder, and inside the cylinder, the pressure and heat makes the Nitrogen atom split from the Oxygen. The oxygen then burns and gives you that sweet KICK. Nitro however is a bit impractical because it's heavy to carry everywhere, can get over quickly, and at times can be so powerful, it can damage engine components if used too often. What increases engine power? More fuel and more air. Specifically, more oxygen. Turbochargers were then developed to force more air into the engine. This worked by taking the exhaust pipe and using the pressure to spin a turbine, which then brought extra air into the engine. This increased performance drastically, and became a common feature in racing and sports cars.
Superchargers, although they sound more epic, are run through a belt from the engine. The belt powers the supercharger and sucks in more air for better combustion. Again, this improved performance drastically, and most muscle cars used these as they were effective and very cool looking. In case you were wondering what those huge things were coming out of muscle car hoods, chances are it's a supercharger intake. In the good old days, engines used to use carburetors to supply air-fuel mixtures to the engine. Carburetors used to combine air and fuel together and send them down a fuel line to the engine. However this was not very efficient.
Later, fuel injection was discovered to be the better option. Air was supplied to the engine and the fuel was directly injected into the cylinder. This increased efficiency and power, and the Mercedes Benz 300SLR Racing car broke a world record by travelling almost 1000 miles in 10 hours. |
