Cars with 8-cylinder engines that offer relatively good gas mileage:
* Luxury Sedans:
* Lexus LS 500: This model gets an EPA estimated 19 mpg city, 31 mpg highway. While not the most frugal, it's a good balance of power and efficiency for a luxury sedan.
* Mercedes-Benz S-Class: Similar to the Lexus, the S-Class gets around 18 mpg city, 28 mpg highway. The newest model, the S 580, is slightly better at 18 city, 27 highway.
* BMW 7 Series: The 7 Series offers a mix of power and efficiency, with the 740i getting 25 mpg city, 34 mpg highway. The V8 option, however, lowers that to 18 mpg city, 26 mpg highway.
* SUVs:
* Audi Q8: This SUV is known for its performance, but the 55 TFSI model offers a decent fuel economy of 19 mpg city, 27 mpg highway.
* BMW X5: The xDrive40i model offers an impressive 22 mpg city, 28 mpg highway.
* Lexus GX 460: This SUV is known for its off-road capabilities, and it also offers 16 mpg city, 20 mpg highway.
Important Considerations:
* Driving Habits: Your actual gas mileage will depend on your driving style, traffic conditions, and the terrain you drive on.
* Engine Size and Technology: Newer 8-cylinder engines often incorporate fuel-saving technologies like cylinder deactivation, direct injection, and turbocharging, which can improve fuel efficiency.
* Hybrid Options: Some luxury brands offer hybrid versions of their large cars that can significantly improve fuel economy.
Alternatives:
* Smaller Engine Options: If fuel efficiency is your primary concern, consider models with smaller engines like a 4-cylinder or a hybrid powertrain. These options will typically offer better gas mileage than a large V8.
Conclusion:
While you can find some big cars with 8-cylinder engines that offer relatively good gas mileage, you'll likely sacrifice some power and performance. If fuel efficiency is your top priority, you may want to consider a smaller car with a more efficient engine.
