The Rezvani Vengeance: Power Meets Practicality?

Let’s be honest: when you hear “Rezvani Vengeance,” the first things that probably come to mind are armored doors, bulletproof glass, and a design that screams “I’m ready for the apocalypse.” This isn’t your average SUV. It’s a statement. A fortress on wheels. But here’s the thing—no matter how cool (or intimidating) a vehicle looks, one question always lingers in the back of your mind: “How much is this beast going to cost me at the pump?”

Fuel consumption isn’t just a number on a spec sheet. It’s real money, real trips to the gas station, and real trade-offs between performance and practicality. Whether you’re considering the Vengeance for its off-road capabilities, its armored security, or just because you want to turn heads at your kid’s soccer game, understanding its fuel economy is crucial. In this post, we’re diving deep into the Rezvani Vengeance fuel consumption—what you can expect, how it compares to similar vehicles, and what you can do to keep those fuel costs under control. Think of this as your honest, no-nonsense guide to the gas mileage of one of the most unique SUVs on the market.

What Influences the Rezvani Vengeance Fuel Consumption?

Before we dive into the numbers, let’s talk about why the Vengeance’s fuel consumption is what it is. It’s not just about the engine. A lot of factors come into play, and understanding them helps you make smarter decisions about how to drive, maintain, and even upgrade your Vengeance.

1. The Engine: Raw Power, Bigger Appetite

The Rezvani Vengeance offers multiple engine options, but the most common (and powerful) is the 6.4L Supercharged V8, cranking out around 1,000 horsepower. Yes, you read that right—1,000 hp. That’s not just muscle; it’s a full-on adrenaline rush. But here’s the catch: more power usually means more fuel burned. A supercharged V8 is like a hungry teenager—it eats constantly, especially when you’re pushing it.

For comparison, a standard 5.0L V8 in a Ford F-150 might sip fuel at 18 mpg highway. The Vengeance? Expect significantly less. We’ll get to the exact numbers in a bit, but just know: this engine is built for performance, not fuel efficiency.

2. Weight: The Armor Adds Up

The Vengeance isn’t just heavy—it’s really heavy. Thanks to its armored body, bulletproof glass, and military-grade materials, it tips the scales at over 6,500 pounds. That’s more than a full-size pickup truck. All that weight means the engine has to work harder to move the vehicle, especially from a stop or up hills. More effort = more fuel.

Think of it like carrying a backpack full of bricks while running. You’ll burn more energy than someone running without it. The same applies here.

3. Aerodynamics: Boxy Shape, Wind Resistance

The Vengeance’s design is all about function and intimidation, not sleek aerodynamics. It’s boxy, tall, and has a lot of frontal area—perfect for looking like a tank, but not so great for slicing through the air. The more wind resistance a vehicle has, the more fuel it needs to maintain speed, especially on the highway.

If you’ve ever driven a large SUV and felt like it “fights” the wind on the freeway, that’s exactly what’s happening with the Vengeance.

4. Driving Habits: Your Foot Matters

This might seem obvious, but your driving style has a huge impact on fuel consumption. If you’re constantly flooring it (which is tempting with 1,000 hp), your fuel economy will tank. Aggressive acceleration, rapid braking, and high speeds all reduce mileage.

On the flip side, smooth, steady driving can make a noticeable difference. Even in a high-performance SUV like the Vengeance, gentle throttle inputs and coasting can save fuel.

5. Terrain and Conditions: Where You Drive Matters

City driving? Expect lower fuel economy due to frequent stops, idling, and traffic. Highway driving? Slightly better, but the Vengeance’s weight and aerodynamics still hold it back. Off-road? Forget about it. Low gears, rough terrain, and constant throttle adjustments can cut fuel economy in half compared to city driving.

And don’t forget weather. Cold temperatures, strong headwinds, and even heavy rain can all reduce fuel efficiency by forcing the engine to work harder.

Real-World Fuel Economy: What to Expect

Now, let’s get to the numbers. Rezvani doesn’t publish official EPA fuel economy ratings (they’re not required to for low-volume manufacturers), so we have to rely on real-world data, owner reports, and educated estimates. Here’s what you can expect based on driving conditions and engine choice.

Engine Options and Estimated MPG

• 6.4L Supercharged V8 (1,000 hp)
  • City: 9–11 mpg
  • Highway: 13–15 mpg
  • Combined: 11–13 mpg
  • Off-road: 6–8 mpg
• 6.2L Supercharged V8 (750 hp)
  • City: 10–12 mpg
  • Highway: 14–16 mpg
  • Combined: 12–14 mpg
  • Off-road: 7–9 mpg
• 5.7L V8 (450 hp)
  • City: 12–14 mpg
  • Highway: 16–18 mpg
  • Combined: 14–16 mpg
  • Off-road: 8–10 mpg

Note: These are estimates based on owner forums, driving reports, and comparisons with similar vehicles (e.g., Hummer H1, Ford F-150 Raptor). Actual results may vary.

Real-World Example: A Week with the 1,000-HP V8

Let’s say you’re driving a 6.4L Vengeance in a mix of city and highway. You do 15 miles in the city, 25 on the highway, and a 5-mile off-road trail (for fun, of course). Here’s how the fuel consumption breaks down:

• City (15 miles at 10 mpg): 1.5 gallons
• Highway (25 miles at 14 mpg): 1.8 gallons
• Off-road (5 miles at 7 mpg): 0.7 gallons
• Total: 4.0 gallons for 45 miles → 11.25 mpg

At $4.00 per gallon, that’s $16.00 for just 45 miles. Not terrible if you’re treating it as a weekend toy, but a real budget-buster if this is your daily driver.

Comparison to Similar Vehicles

How does the Vengeance stack up against other high-performance or armored SUVs?

• Hummer H1 (6.5L diesel): 10–12 mpg city, 13–15 mpg highway
• Mercedes-AMG G63 (4.0L twin-turbo): 13–14 mpg city, 17–18 mpg highway
• Ford F-150 Raptor (3.5L twin-turbo): 15–16 mpg city, 18–20 mpg highway
• Armored Cadillac Escalade: 12–13 mpg city, 16–17 mpg highway (with armor, similar weight)

The Vengeance’s fuel consumption is on par with the Hummer H1 and slightly worse than the G63 or Raptor, but keep in mind: those vehicles aren’t built with the same level of armor and off-road capability. The Vengeance trades fuel efficiency for extreme performance and security.

How to Improve Fuel Economy: Practical Tips

Okay, so the Vengeance isn’t exactly a fuel-sipper. But that doesn’t mean you’re stuck with terrible mileage forever. With a few smart strategies, you can improve fuel economy—sometimes by 10–20%. Here’s how.

1. Drive Smoothly (No Lead Foot!)

This is the biggest win. Avoid aggressive acceleration and hard braking. Instead, accelerate gradually and coast to stops when possible. Think of it like driving a manual transmission: shift up early, keep the revs low, and avoid redlining.

Example: Instead of flooring it from a stoplight, ease into the throttle. You’ll save fuel and reduce wear on the brakes and drivetrain.

2. Maintain Proper Tire Pressure

Underinflated tires increase rolling resistance, which forces the engine to work harder. Check your tire pressure monthly and keep it at the manufacturer’s recommended level (usually around 35–40 psi for the Vengeance).

Tip: Use a quality digital tire pressure gauge. It’s cheap and can save you hundreds in fuel over time.

3. Reduce Weight (If Possible)

The Vengeance is already heavy, but you can still lighten the load by removing unnecessary cargo. That extra 100 pounds of gear in the trunk? It’s costing you fuel. Only carry what you need.

Note: Don’t remove the armor—safety first! But things like spare tools, extra water, or camping gear can be left behind if not needed.

4. Use Cruise Control on the Highway

Maintaining a steady speed reduces fuel consumption compared to constant acceleration and braking. Set your cruise control at or slightly below the speed limit (e.g., 65 mph instead of 75 mph) for better efficiency.

Bonus: Lower speeds also reduce aerodynamic drag, which helps.

5. Keep Up with Maintenance

A poorly maintained engine burns more fuel. Regular oil changes, clean air filters, and proper spark plug maintenance all improve efficiency. Schedule routine check-ups, especially for the supercharger and fuel system.

Pro tip: Use high-quality synthetic oil. It reduces friction and can improve fuel economy by 1–2%.

6. Avoid Idling

Idling burns fuel with no forward progress. If you’re waiting for more than 30 seconds, turn off the engine. Modern engines start quickly and don’t suffer from frequent restarts.

Real-life example: Sitting in a 10-minute school pickup line? Turn it off. You’ll save a quarter-gallon of gas.

7. Plan Your Route

Use GPS to avoid traffic, construction, and hilly terrain. Fewer stops and smoother roads = better fuel economy. Apps like Waze or Google Maps can help you find the most efficient route.

Fuel Costs: What You’re Really Paying

Let’s talk money. Fuel consumption isn’t just about mpg—it’s about how much you’re spending over time. Here’s a breakdown of annual fuel costs for the Vengeance, assuming different annual mileages and gas prices.

Annual Fuel Cost Estimates

Annual Miles	Engine	Est. MPG	Gallons Used	Gas Price ($/gal)	Annual Cost
10,000	6.4L (1,000 hp)	12	833	4.00	$3,332
10,000	6.2L (750 hp)	13	769	4.00	$3,076
10,000	5.7L (450 hp)	15	667	4.00	$2,668
15,000	6.4L (1,000 hp)	12	1,250	4.00	$5,000
15,000	6.2L (750 hp)	13	1,154	4.00	$4,616
15,000	5.7L (450 hp)	15	1,000	4.00	$4,000
20,000	6.4L (1,000 hp)	12	1,667	4.50	$7,502

Let’s put this in perspective. For a 1,000-hp Vengeance driven 15,000 miles a year, you’re looking at $5,000 in fuel costs annually—or about $417 per month. That’s more than some people’s car payments. If gas prices rise to $5.00/gallon, that jumps to $6,250 per year.

Is It Worth It?

That depends on your priorities. If you’re buying the Vengeance for its security, exclusivity, and off-road capability, then yes—the fuel cost is part of the price of admission. But if you’re hoping for a practical daily driver, you might want to reconsider. The Vengeance is a niche vehicle, and fuel economy is one of its trade-offs.

Cost-Saving Tip: Consider the 5.7L Engine

If you don’t need the full 1,000 hp, the 5.7L V8 saves you about $1,000–$1,500 per year in fuel (depending on mileage). You still get the armored body and off-road features, just with slightly less power. For many owners, that’s a smart compromise.

Alternatives and Trade-Offs: Is There a Better Option?

Let’s be real: the Rezvani Vengeance isn’t for everyone. If fuel economy is a top priority, you might want to consider other options—even if they don’t have the same “cool factor.”

1. Armored SUVs with Better Fuel Economy

• Armored Mercedes G-Class: 14–16 mpg combined. Less extreme off-road capability, but better fuel economy and more luxury.
• Armored Range Rover: 16–18 mpg combined. Smooth ride, advanced tech, but less rugged than the Vengeance.
• Armored Lexus LX: 17–19 mpg combined. Reliable, comfortable, and surprisingly capable off-road.

These vehicles offer armor and prestige without the extreme fuel consumption of the Vengeance. If your main concern is security (not 1,000 hp), they’re worth a look.

2. High-Performance SUVs (No Armor)

• Jeep Grand Cherokee Trackhawk: 11 mpg city, 17 mpg highway. 707 hp, no armor, but much lighter and more efficient.
• BMW X5 M: 13 mpg city, 18 mpg highway. 617 hp, luxury interior, better fuel economy.
• Porsche Cayenne Turbo: 15 mpg city, 20 mpg highway. 541 hp, sporty handling, efficient for its class.

These are great if you want performance but don’t need bulletproof glass. They’re also cheaper to buy and maintain.

3. Electric Alternatives (Future-Proof)

Electric SUVs like the Mercedes EQC or Ford Mustang Mach-E offer zero emissions and low operating costs. But they lack the armored security and extreme off-road capability of the Vengeance. For now, EVs aren’t a direct replacement—but keep an eye on the market. Electric armored SUVs could be the next big thing.

The Verdict: Know What You’re Buying

The Vengeance is a specialty vehicle. It’s not designed for fuel efficiency, and that’s okay—as long as you know what you’re getting into. If you’re buying it for its unique blend of power, security, and off-road capability, then the fuel consumption is just part of the package. But if you’re hoping for a practical, fuel-efficient SUV, look elsewhere.

Final Thoughts: Balancing Performance and Practicality

The Rezvani Vengeance is a fascinating vehicle. It’s not just a car—it’s a statement. A symbol of power, security, and exclusivity. But like any high-performance machine, it comes with trade-offs. The Rezvani Vengeance fuel consumption is one of the biggest, and it’s something every potential owner needs to understand.

Yes, you’ll spend more on gas. Yes, you’ll visit the pump more often. But you’re also getting a vehicle that can handle almost anything—whether it’s a rough trail, a security threat, or just turning heads on the street. For some, that’s worth every dollar.

The key is awareness. Know the numbers. Understand the costs. And make smart choices about how you drive and maintain the vehicle. With the right approach, you can enjoy the Vengeance’s incredible capabilities without breaking the bank at the pump.

At the end of the day, the Vengeance isn’t about efficiency—it’s about experience. If you’re ready for that experience, fuel consumption is just part of the journey. And honestly? For the right driver, it’s a journey worth taking.
