Kenworth is a heavy-duty truck manufacturer owned by PACCAR, building Class 8 semi-trucks for long-haul and regional trucking

Kenworth makes diesel-powered tractor units — the powered front half of a semi-truck — not the trailers that attach behind. The company has been building trucks since 1923 and is one of three major Class 8 manufacturers in North America, alongside Volvo and Peterbilt. If you are a trucking company owner, an owner-operator, or a fleet manager, you will encounter Kenworth trucks in the used market or as a new purchase option.

Kenworth trucks range from regional day-cab models (where the driver goes home each night) to long-haul sleeper cabs (where the driver sleeps in the truck). New Kenworth trucks cost between $130,000 and $180,000 depending on engine, transmission, and cab configuration. Used models range from $30,000 for older day-cabs to $80,000 or more for recent sleeper-cab models with low mileage. The actual price depends on model year, engine type, transmission (manual or automatic), mileage, and condition.

Key Takeaways

  • New Kenworth Class 8 trucks cost $130,000 to $180,000; used models range from $30,000 to $80,000 depending on age and mileage.
  • Kenworth offers financing through PACCAR Financial, which typically requires a down payment of 10 to 20 percent and loan terms of 36 to 84 months.
  • Owner-operators and small fleets can deduct truck payments, fuel, maintenance, and insurance as business expenses on Schedule C of their tax return.
  • Diesel fuel costs, engine overhauls, and transmission repairs are the largest operating expenses after the truck payment itself.
  • Used Kenworth trucks from reputable dealers or auctions come with service records that show maintenance history, which affects resale value and reliability.

New Kenworth Truck Pricing and Dealer Inventory

Kenworth dealers stock new trucks with different configurations. A new day-cab (no sleeper) with a manual transmission and standard engine runs around $130,000 to $145,000. A new sleeper-cab with an automatic transmission and upgraded engine can reach $170,000 to $180,000. Prices shift based on supply, fuel costs, and what engines and transmissions are in stock. Dealers can also build custom trucks to order, which takes 8 to 12 weeks and may carry a small upcharge.

Most Kenworth dealers are regional, not national. You find them through the Kenworth website dealer locator or by searching "Kenworth dealer near me." Dealers can show you spec sheets (detailed equipment lists) for trucks in stock and explain the difference between engine options — Cummins, Paccar, and Detroit are the three main diesel engines used in Kenworth trucks. Each has different fuel economy, horsepower, and maintenance costs.

Financing a Kenworth Truck Through PACCAR Financial

PACCAR Financial is the captive finance arm of Kenworth's parent company and is the most common way to finance a new Kenworth. They offer loans to owner-operators, small fleets, and established trucking companies. A typical PACCAR Financial loan requires a down payment of 10 to 20 percent of the truck price, a loan term of 36 to 84 months, and a credit check. Interest rates vary based on your credit score, down payment size, and loan term — longer terms mean lower monthly payments but higher total interest paid.

PACCAR Financial also finances used Kenworth trucks, though rates are higher than for new trucks and the down payment requirement is often 20 to 25 percent. You can explore through a Kenworth dealer or directly through PACCAR Financial's website. The approval process usually takes 3 to 5 business days. If you are denied by PACCAR Financial, you can also approach banks or credit unions that specialize in commercial truck loans, though their rates may be higher.

Operating Costs and Tax Deductions for Owner-Operators

The truck payment is only one part of the cost to own and run a Kenworth. Diesel fuel is the largest variable expense — a truck burning 6 miles per gallon on a 500-mile day uses about 83 gallons, which at current prices can be $250 to $350 per day depending on fuel prices in your region. Oil changes, air filter replacements, and routine maintenance run $1,500 to $3,000 per year. Major repairs — transmission work, engine overhauls, or frame damage — can cost $5,000 to $20,000 or more.

If you are an owner-operator or run a small trucking business, you report income and expenses on Schedule C (Profit or Loss from Business) of your Form 1040 tax return. You can deduct the truck payment (principal and interest), fuel, maintenance, insurance, registration, permits, and depreciation. Depreciation is a non-cash deduction that lowers your taxable income even though you did not spend the money that year. A tax professional who works with trucking businesses can help you track these deductions correctly and may identify deductions you missed.

Used Kenworth Trucks and What to Check Before Buying

Used Kenworth trucks are sold through dealers, auctions (such as Copart or IAA), and private sellers. Dealer trucks usually come with a warranty (often 30 to 90 days on parts and labor) and a service history showing maintenance records. Auction trucks are sold as-is with no warranty, but you can inspect them before bidding and often get a pre-purchase inspection report. Private sales are the cheapest but carry the most risk — you have no recourse if something breaks the day after you buy it.

Before buying a used Kenworth, request the service records and have a trusted mechanic inspect the engine, transmission, frame, and brakes. Check the odometer reading against the maintenance records — if a truck has 500,000 miles but no oil change records in the last 100,000 miles, that is a red flag. Ask about the truck's history: was it used for long-haul, regional, or local work? Long-haul trucks accumulate miles faster but are often better maintained. Regional and local trucks may have lower mileage but harder use (stop-and-go driving, heavy loads, rough roads).

Kenworth Model Options and What They Are Built For

Kenworth makes several Class 8 models for different work. The T680 is the most common long-haul sleeper-cab, designed for fuel economy and driver comfort on interstate routes. The T880 is a regional day-cab or sleeper-cab used for shorter routes where the driver returns home daily or stays out 2 to 3 nights. The T470 is a smaller, lighter truck used for local delivery and construction work. The W990 is a specialized model for severe-duty work like logging, mining, or heavy construction.

Each model comes in different configurations: day-cab (no sleeper), sleeper-cab (with a bunk for the driver), and different wheelbase lengths (the distance from the front axle to the rear axle). A longer wheelbase gives more cargo space but is harder to maneuver in tight spaces. A shorter wheelbase is more agile but carries less freight. The model and configuration you need depends on the type of work — long-haul trucking, regional delivery, or local work — and your budget.

Resale Value and When to Sell or Trade In

A new Kenworth truck loses about 15 to 20 percent of its value in the first year and continues to depreciate as mileage accumulates. A truck with 500,000 miles is worth roughly 30 to 40 percent of its original price. A truck with 1 million miles is worth 15 to 25 percent. Resale value also depends on the engine type (Cummins engines hold value better than some others), maintenance history, and current fuel prices (high fuel prices make fuel-efficient trucks more valuable).

Most owner-operators keep a truck for 5 to 7 years or until it reaches 800,000 to 1 million miles, then sell it or trade it in for a new one. You can trade in your truck at a Kenworth dealer when buying a new one — the dealer will appraise it and credit the value toward your new purchase. You can also sell it privately through classified ads or trucking forums, or sell it to a used truck dealer. Private sales usually bring more money than trade-in value, but take longer and require you to handle paperwork and title transfer yourself.

Frequently Asked Questions

What is the difference between a Kenworth and a Peterbilt?

Both are Class 8 trucks made by PACCAR and share many parts and engines. Kenworth is known for fuel economy and driver comfort; Peterbilt is known for durability and heavy-duty work. The choice often comes down to dealer availability in your area and personal preference. Resale value and operating costs are similar between the two brands.

Can I finance a used Kenworth truck?

Yes, PACCAR Financial and most commercial banks will finance used Kenworth trucks, though interest rates are higher than for new trucks and the down payment is usually 20 to 25 percent. The truck's age, mileage, and condition affect the interest rate and whether a lender will finance it at all.

How often does a Kenworth truck need an engine overhaul?

A well-maintained diesel engine in a Kenworth truck can run 500,000 to 1 million miles before an overhaul is needed. Regular oil changes, fuel filter replacements, and air filter changes extend engine life. An overhaul costs $8,000 to $15,000 depending on the engine type and damage.

What is the fuel economy of a new Kenworth truck?

A new Kenworth T680 with an efficient engine and transmission typically gets 6 to 7 miles per gallon on the highway. Older trucks and trucks with less efficient engines may get 5 to 6 miles per gallon. Fuel economy depends on engine type, transmission, driving habits, load weight, and road conditions.

Do I need a special license to drive a Kenworth truck?

Yes, you need a Commercial Driver License (CDL) with a Class A endorsement to drive any Class 8 truck, including a Kenworth. You must pass a written test, a pre-trip inspection test, and a road test. Requirements vary by state, so check your state's Department of Motor Vehicles for specific rules.
