Gas vs. Diesel Showdown: Choosing the Right Engine for Your 2023 Chevrolet Express 3500 Cutaway
There is a lot of satisfaction in ordering a commercial vehicle and knowing you have the perfect powertrain for the job—whether you’re hauling a heavy ambulance body or a passenger-filled shuttle bus. But here is the thing about the 2023 Express 3500 Cutaway: the engine choice is now simpler than ever because Chevrolet made a big change. Let’s break down your options.
TL;DR
For the 2023 model year, Chevrolet discontinued the 2.8-liter Duramax diesel engine for the Express lineup . Your choices are now exclusively gasoline: a fuel-efficient 4.3L V6 or a powerful 6.6L V8 . The V6 is a solid, economical choice for lighter duties, while the V8 provides the muscle needed for heavy commercial applications like ambulances. There is no diesel option for 2023, simplifying the decision for fleet managers and upfitters.
Key Takeaways
- No Diesel in 2023: The diesel engine is gone for this model year. Your choice is between two proven gas engines .
- V6 for Efficiency: The 4.3L V6 (276 hp, 298 lb-ft) is the standard engine, ideal for lighter shuttle bus configurations and operations where fuel economy is a priority .
- V8 for Power: The 6.6L V8 (401 hp, 464 lb-ft) is the heavy-hitter, mandatory for the YF2 Ambulance Package and recommended for any application requiring maximum payload and towing .
- Simplified Choice: With the diesel removed, the decision is straightforward: choose the engine that matches your power requirements .
Why the Diesel Engine Was Discontinued
The most significant news for the 2023 Express is the deletion of the 2.8-liter Duramax inline-four diesel. This is a big change from previous years . According to Car and Driver, Chevrolet not only removed the engine but also eliminated related features like the exhaust brake and the auxiliary heat generator for the Cold Climate Package .
For commercial buyers, this might feel like a loss. Diesel engines traditionally offer better fuel economy and more low-end torque for heavy hauling. However, for the 2023 Express, the decision was made to focus entirely on the gasoline powertrains.
The Gasoline Engine Options: What You Get
With the diesel out of the picture, the focus is on Chevrolet’s proven gasoline V6 and V8 engines. Both are conventional, robust, and built for the demands of commercial work .
1. The Standard: 4.3L V6
The 4.3L V6 is the standard engine on many Express Cutaway configurations . It is a modern engine with Direct Injection and Variable Valve Timing .
- Power: 276 horsepower @ 5,200 rpm .
- Torque: 298 lb-ft @ 3,900 rpm .
- Transmission: Paired with an 8-speed automatic transmission with overdrive and tow/haul mode .
- Best For: Lighter-duty shuttle buses, utility bodies, or operations where payload is not at maximum capacity. It is not available with the heavy-duty Ambulance Package .
2. The Heavy-Duty Choice: 6.6L V8
The 6.6L V8 is the engine to choose if you need serious muscle. This engine is standard equipment for the YF2 Ambulance Package and is the right choice for demanding commercial applications .
- Power: 401 horsepower @ 5,200 rpm .
- Torque: 464 lb-ft @ 4,000 rpm .
- Transmission: Paired with a 6-speed automatic transmission .
- Best For: Ambulances, heavy shuttle buses, and any application requiring maximum payload or towing. The additional torque of the V8 is crucial for moving heavy loads with confidence .
Comparison: V6 vs. V8 for Commercial Use
This table breaks down the key differences to help you decide.
| Engine | Horsepower | Torque | Transmission | Best For |
|---|---|---|---|---|
| 4.3L V6 | 276 hp | 298 lb-ft | 8-speed Automatic | Lighter-duty shuttle buses, standard cargo |

Timeline: The Evolution of the Express Powertrain
Understanding the history of the Express engine lineup helps put the 2023 changes into perspective.
- 1996: The Express is introduced, replacing the G-Series van. It offers a range of engines, including gasoline V6 and V8 options and a 6.5L turbo diesel V8 .
- 2006: The more modern Duramax 6.6L V8 diesel is introduced, offering significant power for heavy-duty applications .
- 2017: A smaller 2.8L Duramax turbo diesel I4 is offered, providing a fuel-efficient alternative to the bigger V8 diesel .
- 2020: The 6.6L V8 gasoline engine is introduced, offering 401 horsepower and replacing the older 6.0L V8 .
- 2023: Chevrolet discontinues the 2.8L Duramax diesel, making the 4.3L V6 and 6.6L V8 the only choices .
What This Means for Your Commercial Upfit
The absence of a diesel option simplifies your decision-making process. Your choice is no longer about the diesel vs. gas debate but about the specific power requirements of your job.
- Shuttle Bus Operators: If your primary concern is moving passengers efficiently and you don’t have extreme weight demands, the 4.3L V6 is likely your ticket to better fuel economy and lower upfront costs.
- Emergency Service Providers: The Ambulance Package (YF2) requires the 6.6L V8 . The extra horsepower and torque are non-negotiable for a vehicle that must perform in critical situations.
- Heavy Haulers: The 6.6L V8 is the only choice for maximum towing and payload. It provides the brute force needed to handle heavy bodies and equipment without straining.
“Chevy’s Express gives buyers a choice of powertrains… It produces 401 horsepower and 464 pound-feet of torque, and it’s teamed with a six-speed automatic gearbox. The Express handles like the big vehicle that it is. Still, its engine lineup is competent, generating the power needed to tackle the task of towing a trailer or hauling a full load of passengers.”
