Most 4Runners Are 4WD, But Some Models Offer RWD Instead

Toyota stopped making rear-wheel-drive 4Runners in 2009. Every 4Runner sold in the United States since 2010 has come standard with four-wheel drive — there is no two-wheel-drive option on the current generation. If you are shopping for a used 4Runner from 2010 onward, you will get 4WD regardless of trim level or year.

Before 2010, the picture was different. From 1984 to 2009, Toyota offered 4Runners in both rear-wheel drive and four-wheel drive, and RWD was often the base model. If you are looking at a used 4Runner from 2009 or earlier, the drive system depends on which one the original owner chose — you cannot assume it has 4WD just because it is a 4Runner.

The shift to standard 4WD happened when Toyota redesigned the 4Runner for the 2010 model year. The company made four-wheel drive the only option, meaning every vehicle rolling off the lot came with the same drivetrain. This change reflected the market demand for SUVs with off-road capability and the rising cost of maintaining two separate production lines.

Key Takeaways

  • All 4Runners from 2010 to present come standard with four-wheel drive; there is no RWD option.
  • 4Runners built between 1984 and 2009 were available in both RWD and 4WD, so you must check the specific vehicle's documentation.
  • The vehicle's title, window sticker, or owner's manual will show the drivetrain if you are unsure about a used model.
  • Four-wheel drive adds weight and reduces fuel economy compared to RWD, but provides traction in snow, mud, and off-road terrain.

How to Check the Drivetrain on a Used 4Runner

If you are buying a used 4Runner from 2009 or earlier, the easiest way to confirm the drivetrain is to look at the vehicle's title or registration. The title will list whether it is 4WD or 2WD. You can also check the original window sticker (Monroney label) if the seller still has it — this label was affixed to the window when the vehicle was new and shows every option the buyer selected, including the drivetrain.

The owner's manual also states the drivetrain in the specifications section. If you do not have the manual, you can request one from Toyota or read it from Toyota's website using the vehicle identification number (VIN). The VIN itself contains a code that identifies the drivetrain, but decoding it requires knowledge of Toyota's system — asking the seller or a Toyota dealer is faster.

A physical inspection can give you clues, but it is not definitive. Four-wheel-drive 4Runners have a transfer case (a second transmission that routes power to all four wheels), which adds visible components underneath the vehicle. RWD models lack this. If you are not comfortable crawling under a vehicle, a pre-purchase inspection by a mechanic who knows 4Runners will confirm the drivetrain in minutes.

Why Toyota Made 4WD Standard in 2010

The 2010 redesign coincided with a shift in how consumers viewed SUVs. By the late 2000s, buyers increasingly wanted vehicles that could handle rough terrain and winter weather, and 4WD was becoming the expected feature rather than an upgrade. Toyota also simplified its manufacturing by eliminating the RWD option, which reduced complexity and costs in the production line.

The 4Runner's reputation as a capable off-road vehicle also played a role. Marketing a vehicle called "4Runner" with only rear-wheel drive created a mismatch between the name and the product. Making 4WD standard aligned the vehicle's capabilities with its identity and the expectations of buyers who chose it over other SUVs.

Fuel Economy and Weight Differences Between RWD and 4WD 4Runners

Four-wheel drive adds approximately 200 to 300 pounds to a 4Runner compared to an equivalent RWD model, depending on the generation. This extra weight comes from the transfer case, front differential, front axles, and additional driveshafts. The added weight reduces fuel economy by roughly 1 to 3 miles per gallon in real-world driving, though the exact difference varies with driving habits and conditions.

Older 4Runners (1984–2009) that came in RWD typically achieved slightly better highway fuel economy than their 4WD counterparts. A 2009 RWD 4Runner might see 18 to 20 mpg on the highway, while a 4WD version of the same year would see 16 to 18 mpg. Modern 4Runners (2010 and later) are heavier overall, so the fuel economy gap between a hypothetical RWD and the standard 4WD is less dramatic in percentage terms, but the weight penalty still exists.

The trade-off is traction and capability. Four-wheel drive provides better grip in snow, mud, sand, and rocky terrain. For buyers who never encounter those conditions, RWD would have been more economical. For those who do, the 4WD system pays for itself in safety and capability.

What Happens If You Need 4WD on a Pre-2010 RWD 4Runner

If you own a 1984–2009 4Runner that came with RWD and you later need four-wheel drive, retrofitting is possible but expensive and complex. A full 4WD conversion requires replacing the frame, axles, transfer case, driveshafts, and suspension components. The cost typically ranges from $8,000 to $15,000 or more, depending on the year and condition of the vehicle, and it requires specialized knowledge.

Most owners in this situation find it more practical to sell the RWD 4Runner and purchase a 4WD model instead. The resale value of an RWD 4Runner is lower than a 4WD version of the same year, so the gap between what you can sell it for and what a 4WD model costs is often smaller than the conversion expense.

If you are considering an older 4Runner and think you might need 4WD, prioritize finding one that was originally equipped with it. The cost difference between an RWD and 4WD model from the same year is usually $2,000 to $4,000, which is far less than a retrofit.

Transmission and Engine Options Do Not Affect 4WD Availability

On current 4Runners (2010 and later), the drivetrain is 4WD regardless of which engine or transmission you choose. Toyota offers the 4Runner with a 4.0-liter V6 engine and a five-speed automatic transmission across all trim levels, and every combination includes four-wheel drive. There is no base model with a smaller engine and RWD, and there is no premium trim that adds 4WD as an upgrade — it is standard across the board.

On older 4Runners (1984–2009), the drivetrain and engine/transmission were separate choices. You could order a 4Runner with a V6 and RWD, or a V6 and 4WD, or other combinations. The engine and transmission did not determine whether the vehicle had 4WD — the buyer's choice did. This is why checking the original window sticker or title is the only reliable way to know what drivetrain an older 4Runner has.

Frequently Asked Questions

Can I tell if a 4Runner is 4WD just by looking at it?

Not reliably from the outside. A 4WD 4Runner may have slightly different undercarriage components, but spotting these differences requires getting underneath the vehicle or having mechanical knowledge. The safest approach is to check the title, window sticker, or have a mechanic inspect it.

Do all 4Runner trim levels come with 4WD?

Yes, on all 4Runners from 2010 onward. Every trim level — SR5, Limited, TRD Pro, and others — comes standard with four-wheel drive. On older models (1984–2009), trim level did not determine the drivetrain; the buyer's choice did.

What does the VIN tell me about a 4Runner's drivetrain?

The VIN contains a code for the drivetrain, but decoding it requires knowledge of Toyota's VIN system. A Toyota dealer can decode it for you in seconds, or you can ask the seller or a pre-purchase mechanic. It is faster than trying to decode it yourself.

Is a used RWD 4Runner from 2009 cheaper than a 4WD version?

Yes, typically $2,000 to $4,000 less, depending on condition and mileage. However, if you need 4WD capability, the price difference is worth paying upfront rather than attempting an expensive retrofit later.

Do newer 4Runners have better 4WD systems than older ones?

Yes. Modern 4Runners have more advanced transfer cases, electronic locking differentials, and traction control systems compared to 1980s and 1990s models. The 4WD system is more capable and easier to use, though older systems are still functional for most driving conditions.
