Rezvani Tank Fuel Consumption What You Need to Know

The Rezvani Tank delivers extreme off-road performance at the cost of exceptionally high fuel consumption, averaging just 10–13 mpg in combined driving. With its supercharged V8 engine and armored military-inspired design, this powerhouse prioritizes rugged capability over efficiency, making fuel economy a secondary concern for thrill-seeking owners.

Key Takeaways

• Fuel efficiency is low: Expect 10-12 MPG due to its heavy, armored design.
• Engine choice matters: The V6 offers better mileage than the V8 option.
• City driving drains fuel: Stop-and-go traffic significantly reduces fuel economy.
• Plan for premium fuel: Higher octane improves performance and engine longevity.
• Off-roading increases consumption: Rough terrain can cut MPG by up to 30%.
• Regular maintenance helps: Clean filters and proper tire pressure optimize fuel use.

The Rezvani Tank: A Beast on the Road

Imagine driving a vehicle that looks like it rolled out of a post-apocalyptic action movie—armored, rugged, and unapologetically bold. That’s the Rezvani Tank for you. With its military-inspired design and aggressive stance, it’s not just a car; it’s a statement. But behind the armored doors and bulletproof windows lies a question that every potential buyer or curious car enthusiast wants to answer: What’s the Rezvani Tank fuel consumption really like?

Let’s be real—when you’re considering a vehicle this extreme, fuel efficiency probably isn’t the first thing on your mind. You’re more focused on survival gear, bulletproof armor, and maybe even a thermal night vision system (yes, it has that). But if you plan to actually drive this beast beyond the city limits or use it as a daily driver—even occasionally—fuel consumption becomes a very real concern. After all, you don’t want your “tank” to run out of gas before you’ve even hit the highway.

Understanding the Rezvani Tank’s Powertrain and Fuel Type

The Rezvani Tank isn’t your average SUV. Under the hood lies a serious powertrain designed to match its intimidating presence. Depending on the model year and configuration, the Tank typically comes with either a supercharged 6.2L V8 engine (based on the GM LT4) or a 3.6L V6 engine in more basic trims. But when it comes to fuel consumption, the V8 is where the real story begins.

Engine Options and Their Fuel Demands

• Supercharged 6.2L V8 (LT4): This engine produces up to 707 horsepower and 648 lb-ft of torque. It’s the same engine used in high-performance Corvettes and Camaros. While it delivers jaw-dropping acceleration (0-60 mph in under 4 seconds), it also demands a lot from your wallet at the pump.
• 3.6L V6 (LFX): Found in base models, this engine offers a more manageable 308 horsepower. It’s less thirsty than the V8, making it a better option if you’re trying to balance performance with practicality.

Both engines run on premium unleaded gasoline (91 octane or higher), which already sets the stage for higher fuel costs. Premium fuel is more expensive than regular, and the Tank’s large engine displacement means it burns through it fast.

Why Engine Choice Matters for Fuel Consumption

Think of it like this: the V8 is like a professional sprinter—fast, powerful, but needs constant refueling. The V6 is more like a long-distance runner—less explosive, but better at pacing itself over time. If you’re buying the Tank for its looks and occasional off-road adventures, the V6 might save you hundreds of dollars a year in fuel. But if you want that heart-pounding acceleration and the ability to tow heavy loads, the V8 is the way to go—just be ready to pay the price at the pump.

For example, one owner shared on a Rezvani forum that after driving his V8-powered Tank for 1,200 miles over three months (mostly city driving), he spent over $800 on fuel alone. That’s roughly $0.67 per mile—not including maintenance or insurance.

Real-World Rezvani Tank Fuel Consumption: What the Numbers Say

Now, let’s get to the heart of the matter: How much fuel does the Rezvani Tank actually use? The official EPA estimates don’t exist for the Rezvani Tank because it’s a low-volume, specialty vehicle built on a modified Jeep Wrangler chassis. So, we have to rely on real-world data, owner reports, and engineering analysis to get a clear picture.

Estimated Fuel Economy by Model

Based on aggregated data from forums, YouTube reviews, and owner surveys, here’s a breakdown of average fuel consumption:

Model	Engine	City (MPG)	Highway (MPG)	Combined (MPG)	Fuel Tank Capacity	Estimated Range (Highway)
Rezvani Tank (Base)	3.6L V6	14–16	18–20	16–18	21.5 gal	~430 miles
Rezvani Tank (V8)	6.2L Supercharged V8	10–12	13–15	11–13	21.5 gal	~300 miles
Rezvani Tank X (Off-Road)	6.2L Supercharged V8	8–10	12–14	10–12	21.5 gal	~270 miles

Note: These figures are estimates based on real-world driving conditions, including city traffic, highway cruising, and occasional off-road use. Actual results may vary depending on driving habits, terrain, and vehicle modifications.

What Affects Fuel Consumption in Real Life?

Fuel economy isn’t just about engine size—it’s influenced by a dozen factors, especially in a vehicle as unique as the Tank. Here are the top contributors:

• Weight: The Tank can weigh over 5,000 lbs (especially with armor). More weight = more fuel to move it.
• Aerodynamics: That boxy, upright shape creates a lot of drag. At highway speeds, the engine works harder to push air aside.
• Off-road use: Driving on sand, mud, or steep inclines drastically reduces fuel efficiency. One owner reported dropping to 6 MPG during a weekend desert trail run.
• Driving style: Aggressive acceleration and high speeds burn fuel fast. The V8 loves to rev—and so do its drivers.
• Accessories: Running lights, winches, or climate control in extreme weather adds electrical load, which the engine compensates for.

For instance, a YouTuber who tested a V8 Tank on a 150-mile mixed route (70% highway, 30% city) averaged just 11.2 MPG. He noted that even with cruise control set at 70 mph, the engine was constantly adjusting to wind and road resistance.

Factors That Influence Rezvani Tank Fuel Consumption

So, what makes the Rezvani Tank so fuel-thirsty? It’s not just the engine—it’s the whole package. Let’s break down the key factors that shape its fuel consumption, so you can understand what you’re signing up for.

1. Vehicle Weight and Armor

The Rezvani Tank can be outfitted with ballistic-grade armor, bulletproof glass, and even run-flat tires. While these features make it one of the safest civilian vehicles on the road, they add serious weight. A fully armored Tank can weigh 1,000–1,500 lbs more than a standard Jeep Wrangler.

Think of it like carrying a backpack full of bricks while running. The engine has to work harder to accelerate, climb hills, and maintain speed. This directly impacts fuel economy—especially in stop-and-go city traffic.

2. Aerodynamics: The Boxy Dilemma

Let’s be honest: the Tank isn’t designed for wind tunnels. Its upright windshield, flat sides, and roof-mounted gear create massive air resistance. At 70 mph, aerodynamic drag accounts for over 60% of the energy required to keep the vehicle moving.

Compare that to a sleek sedan or crossover, which slices through the air with minimal resistance. The Tank, on the other hand, pushes through it like a brick wall. This is why highway fuel economy is still modest—even though the engine is more efficient at steady speeds.

3. Tire Size and Terrain

Most Rezvani Tanks come with oversized all-terrain or mud-terrain tires (up to 37 inches). These tires have aggressive tread patterns that increase rolling resistance. In simple terms, they make the engine work harder just to roll forward.

Plus, driving on soft surfaces like sand, snow, or mud can reduce fuel efficiency by 20–40%. One owner in Colorado reported that his Tank’s fuel economy dropped from 14 MPG on pavement to just 8 MPG during a snowy mountain trip.

4. Driving Habits and Conditions

Your personal driving style plays a huge role. If you love to “floor it” at every green light, you’ll see your fuel gauge drop fast. The V8 engine delivers instant torque, and it’s tempting to use it. But aggressive driving can reduce fuel economy by up to 30% in city traffic and 15% on the highway.

Also, extreme temperatures affect fuel consumption. Cold engines take longer to warm up, and air conditioning in summer or heating in winter increases load on the engine. One owner in Arizona said his Tank’s fuel economy dropped by 2 MPG during a heatwave when the AC ran nonstop.

5. Modifications and Add-Ons

Many Tank owners customize their vehicles with winches, rooftop tents, light bars, and extra fuel cans. While these are great for off-road adventures, they add weight and drag. A rooftop tent alone can add 100+ lbs and increase aerodynamic drag by 10–15%.

Even something as simple as a bull bar or skid plate adds weight. Every extra pound matters when you’re pushing a 5,500-lb vehicle down the road.

Tips to Improve Rezvani Tank Fuel Efficiency

Now, don’t panic. Just because the Rezvani Tank is a fuel guzzler doesn’t mean you’re doomed to spend a fortune on gas. With a few smart strategies, you can stretch your miles per gallon and make your Tank a little more wallet-friendly.

1. Drive Smoothly and Use Cruise Control

Smooth acceleration and steady speeds are key. Avoid rapid starts and hard braking. Use cruise control on highways to maintain a consistent speed—this reduces unnecessary throttle adjustments.

Pro tip: If you’re on a long trip, set your cruise control to 65–70 mph instead of 75+. The difference might seem small, but fuel economy drops sharply above 70 mph due to increased drag.

2. Maintain Proper Tire Pressure

Underinflated tires increase rolling resistance. Check your tire pressure monthly, especially before long trips. The recommended pressure for a Tank with 37-inch tires is usually around 35–38 PSI, but always check your owner’s manual or door jamb sticker.

One owner shared that inflating his tires to the correct pressure improved his fuel economy by nearly 2 MPG—a small change with a big payoff.

3. Reduce Weight When Possible

Only carry what you need. If you’re not planning to off-road, leave the extra gear (like spare tires, winches, or rooftop tents) at home. Every 100 lbs of extra weight reduces fuel economy by 1–2%.

Also, consider removing non-essential armor for daily driving. While it’s great for security, it’s not needed for a trip to the grocery store.

4. Use Premium Fuel Wisely

While the engine requires premium fuel, you don’t always need to run it at 93 octane. If you’re doing light city driving or short trips, 91 octane is often sufficient. Save the 93 octane for highway driving or when you need peak performance.

But never use regular unleaded—it can cause engine knocking and damage the supercharger in V8 models.

5. Schedule Regular Maintenance

A well-maintained engine runs more efficiently. Change the oil and air filter on time, and keep the spark plugs and fuel injectors clean. Clogged filters or dirty injectors make the engine work harder, increasing fuel consumption.

One owner noticed a 1.5 MPG improvement after replacing his clogged air filter and doing a fuel system cleaning.

6. Plan Your Routes

Use GPS apps to avoid traffic, steep hills, or rough terrain when possible. Smooth, flat roads are much kinder to your fuel tank. If you’re planning a long trip, consider refueling at stations with lower prices—even if it means driving a few extra miles.

Comparing the Rezvani Tank to Similar Vehicles

How does the Rezvani Tank stack up against other rugged, high-performance SUVs? Let’s compare it to a few key competitors to see where it fits in the fuel economy spectrum.

Rezvani Tank vs. Jeep Wrangler

The Tank is built on a modified Jeep Wrangler chassis, so this comparison is natural. A stock Wrangler with a 3.6L V6 gets about 17 MPG city / 23 MPG highway. The Rezvani Tank with the same engine gets 14–16 MPG city / 18–20 MPG highway—slightly worse due to added weight and drag.

But when you step up to the V8-powered Wrangler (Rubicon 392), it gets 13 MPG city / 17 MPG highway—very close to the Tank’s V8 numbers. The difference? The Wrangler is lighter and more aerodynamic, so it’s slightly more efficient.

Rezvani Tank vs. Mercedes-Benz G-Class

The G-Class is another luxury off-roader with a cult following. The AMG G 63, with its 577-hp V8, gets 13 MPG city / 16 MPG highway. That’s actually better than the Rezvani Tank V8 in the city, thanks to advanced transmission and aerodynamics.

But the G-Class starts at over $150,000—nearly double the price of a base Tank. So, while it’s slightly more efficient, it’s not a fair cost comparison.

Rezvani Tank vs. Ford F-150 Raptor

The Raptor, with its twin-turbo V6, gets 15 MPG city / 18 MPG highway. It’s more efficient than the Tank V8 and offers similar off-road capability. But the Raptor is a pickup, not a fully armored SUV, so it lacks the Tank’s extreme security features.

If fuel economy is your top concern, the Raptor might be a better choice. But if you want bulletproof armor and military-grade looks, the Tank wins—even if it costs more to fuel.

Final Thoughts: Is the Rezvani Tank Worth the Fuel Cost?

Let’s cut to the chase: the Rezvani Tank fuel consumption is not for the faint of heart—or the tight of budget. With the V8 engine, you’re looking at $80–$120 to fill the tank and a range of just 250–300 miles on the highway. If you drive 12,000 miles a year, you could spend $3,000–$4,500 annually on fuel alone.

But here’s the thing: people don’t buy the Rezvani Tank for fuel efficiency. They buy it for the experience—the thrill of driving a vehicle that turns heads, handles off-road terrain like a beast, and offers unparalleled security. It’s a lifestyle choice, not a practical one.

If you’re using it as a weekend adventure vehicle or a statement piece in the city, the fuel cost is just part of the package. But if you’re planning to drive it daily or on long road trips, you’ll need to budget carefully.

Ultimately, the Rezvani Tank is like a high-performance sports car disguised as an armored truck. It’s not meant to be efficient—it’s meant to be awesome. And if you can afford the fuel, the fun is absolutely worth it.
