What is a good car to get that fast and on gas?

It's impossible to give a definitive answer to "fast and on gas" without understanding your priorities and budget. "Fast" and "on gas" are often conflicting goals, as performance often comes with a higher fuel consumption rate.

To help me give you a better recommendation, please tell me:

* What's your budget? (This will significantly narrow down the possibilities)

* What type of car are you looking for? (Sedan, SUV, hatchback, etc.)

* What kind of performance are you looking for? (0-60 mph time, top speed, handling, etc.)

* What kind of fuel economy are you looking for? (MPG, range, etc.)

* What are your daily driving needs? (City, highway, commute, etc.)

Once I understand your needs and priorities, I can provide you with a list of cars that meet your requirements.

Here are some general examples of cars that are both fast and relatively fuel-efficient:

* Hybrids: Many hybrids offer impressive fuel economy without sacrificing performance. Examples include the Toyota Prius, Honda Insight, and Hyundai Ioniq.

* Small Turbocharged Engines: Cars with small, turbocharged engines can offer a good balance of power and fuel economy. Examples include the Mazda3 Turbo, Volkswagen GTI, and Ford Focus ST.

* Electric Vehicles: Electric vehicles have the potential for incredible efficiency, especially in urban environments. However, their range can be limited. Popular examples include the Tesla Model 3, Chevrolet Bolt, and Nissan Leaf.

Remember, the best car for you depends on your individual needs and preferences. Don't hesitate to provide more information so I can give you a more personalized recommendation!
