The 2017 Kia K900 with its 5.0-liter V8 engine gets an EPA-estimated 18 MPG combined. This places it in a category of large luxury cars that don’t prioritize gas mileage. This isn’t a car for someone obsessed with fuel efficiency, it’s a sign of achieving a certain status, a way to show success where comfort and prestige are more important than saving money at the gas pump. The K900 buyer wants a smooth, quiet ride and plenty of power for easy cruising, and accepts the fuel consumption as part of the cost.

City and highway performance

The official EPA estimates show 15 MPG in the city. This reflects the demands of stop-and-go traffic and the engine working harder to move the K900’s weight. It performs better on the highway, achieving 23 MPG. This difference highlights its ability as a long-distance cruiser, where the V8 can run at a relaxed pace and the 8-speed automatic transmission helps maximize efficiency. Remember that these are EPA estimates, driving harder or faster will reduce your mileage. You can view K900 MPG across all years on our website.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Kia K900 5.0L V8 at $3,200. This is based on driving 15,000 miles per year with a mix of city and highway driving, and using the national average fuel prices at the time of calculation. How much you spend on gas will change depending on how you drive, where you live, and gas prices, but $3,200 is a good number to compare your own costs against.

Real-world expectations

While the EPA estimates give a baseline, real-world fuel economy can change based on different things. Accelerating hard, making lots of short trips where the engine stays cold, and carrying extra weight in the car all lead to worse MPG. On the other hand, accelerating gently, driving at consistent speeds on the highway, and keeping your tires properly inflated can help you get closer to the EPA estimates. The K900’s trip computer shows real-time and average fuel economy data, so drivers can watch their consumption and adjust how they drive. Pay attention to it!

How it compares

The 2017 Kia K900 5.0L V8 is in a class where fuel economy matters less than power and luxury. The Lexus LS 460, another V8-powered luxury sedan, gets about 19 MPG combined. The BMW 750i xDrive, with its turbocharged V8 and all-wheel drive, gets a little better at 20 MPG combined. Choosing a lower trim level on some competitors doesn’t help much. The Genesis G90 with its available 3.3T V6 only gets a slightly better 20 MPG combined. The K900 buyer isn’t considering a Prius, they are looking at top-of-the-line models from famous luxury brands, and the Kia’s gas mileage is similar to other cars in that group.

Tips to maximize efficiency

The K900’s 5.0L V8 works best with smooth, gradual acceleration. Avoid quick starts and stops, and try to keep a consistent speed. This will improve fuel economy and make driving more enjoyable, letting you enjoy the engine’s power.

Tire pressure is important for fuel efficiency. Check your tires often and make sure they have the right amount of air, which you can find on a sticker inside the driver’s side door. Tires with low pressure create more resistance, making the engine work harder and burn more fuel.

Don’t carry extra weight. Extra weight lowers fuel economy, so take out anything you don’t need from your trunk or backseat. This simple thing can make a difference over time, especially when driving in the city.

Think about using the K900’s Eco driving mode, if it has one. This mode changes how the accelerator responds and when the transmission shifts gears to save fuel. It might reduce performance a little, but it can help you save gas during normal driving.

Regular maintenance is key for good fuel economy. Make sure your K900 gets oil changes, tune-ups, and other services as recommended. An engine that is well-maintained runs better and uses less fuel. Spark plugs, air filters, and even wheels that are aligned correctly can all help increase MPG.
