Could someone help me improve this sentence so it is more understandable and has better word choice?

You now know that a wasting gas car is no comparison to a saving electric car.

Now you know that ecology-friendly cars are no comparison to the gas-guzzlers.

Thank You!

You're welcome.

Certainly! In order to improve the sentence for better clarity and word choice, you can consider the following revision:

"You are now aware that an electric car, which conserves energy, is incomparable to a gas-guzzling vehicle."

In this revised sentence, I replaced "wasting gas car" with "gas-guzzling vehicle," which better conveys the idea of a car consuming a large amount of gasoline. Additionally, I changed "saving" to "conserves energy" to more accurately describe the electric car's efficiency.
