How Many Miles per Gallon Does a Suburban Get

How Many Miles per Gallon Does a Suburban Getの全体像を詳しく解説してご紹介します。

Here’s a weird twist: there’s a diesel version. It’s a 3.0-liter Duramax engine. That baby bumps the highway number to 26 mpg.

Yes, a three-ton metal box can hit 26 mpg. That’s almost respectable. But you’ll pay extra for that engine. And diesel fuel costs more.

So the gas version? It’s basically a conversation starter at the pump. “Wow, that thing must be thirsty,” they’ll say. You’ll nod. You’ll smile. You’ll swipe your card.

Fun Fact: The Old Ones Were Worse

Remember the 1990s Suburbans? They got 10 to 12 mpg. Driving one was like drinking gasoline through a straw.

Modern engineering is a miracle. Today’s Suburban has an eight-speed or ten-speed transmission. It has cylinder deactivation. It shuts off half its cylinders on the highway.

That’s right. Your giant SUV sometimes runs like a V4 engine. It’s a shape-shifting gas guzzler.

What About the Big V8?

Most Suburbans have a 5.3-liter or 6.2-liter V8. The 6.2-liter is a monster. It makes 420 horsepower. It also makes your gas gauge drop like a rollercoaster.

With the 6.2, you’ll get about 14 city / 19 highway. That’s if you drive like a nun. If you stomp on it? Expect single digits.

But here’s the secret: nobody buys a Suburban for fuel economy. They buy it for the space. You can fit 9 people. You can tow a boat. You can haul a refrigerator with the seats folded.
