The Chevrolet Express Cutaway van is known by customers and upfitters alike for the flexibility and durability of its three available wheelbases, single or dual rear wheels and three engine choices – including the powerful Duramax 6.6L turbo-diesel.
For 2015, the Express Cutaway continues to provide options for a variety of uses, and introduces a few new items, including two new exterior color choices: Red Hot and Rainforest Green Metallic.
Additionally for 2015, the Express features a 9,900 pounds GVWR (4,490 kg) with the 159-inch wheelbase, along with higher GVWRs on 3500 models, including 10,050 pounds (4,559 kg) and 10,100 pounds (4,581 kg) and 12,300 pounds (5,591kg). The 4500 models have a maximum GVWR of 14,200 pounds (6,441 kg).
Special-equipment packages also are available for ambulance, RV, shuttle bus and school bus construction.

Express powertrains – 6.6L Duramax diesel
The powerful Duramax turbo-diesel V-8 is offered in Express Cutaway, delivering best-in-class torque and horsepower. Known by its “LGH” engine code, it is rated at 260 horsepower (194 kW) and 525 lb-ft of torque (711 Nm).
The LGH Duramax employs a robust EGR cooling system, along with revised turbocharger tuning that helps enhance EGR performance. It also has a large-capacity selective catalytic reduction system. In fact, the engine features the latest in emission control technology, making it the cleanest Duramax engine ever produced. NOx emissions are controlled via a Selective Catalyst Reduction aftertreatment system that uses urea-based Diesel (Emission) Exhaust Fluid (DEF). The DEF is housed in a 5.83-gallon (20 L) tank and needs to be replenished about every 5,000 miles (8,000 km). Electrically heated lines feed the DEF to the emission system to ensure adequate delivery in cold weather.
The Duramax also includes GM’s second-generation diesel particulate filter system. Unlike most competitors’ systems, the Duramax regenerates its diesel particulate filter using a downstream injection of diesel fuel directly into the exhaust stream and can travel up to 700 miles (1,125 km) between regenerations – a 300-mile (482 km) increase over the previous Duramax engine. The use of downstream injection also helps improve engine life by eliminating concerns about the possibility of diesel fuel contaminating engine oil, which can happen when fuel used for regeneration is introduced directly into the cylinder.
Express Cutaway also provides outstanding cold-weather performance, thanks to the Duramax’s microprocessor-controlled glow plugs, which are capable of a gas engine-like start performance in less than three seconds in temperatures as low as -20 degrees F (-29 o C), without a block heater. The engine has been developed to operate for at least 200,000 miles (322,000 km) on a rough-duty cycle without the need for a major overhaul. It is also backed with a five-year/100,000-mile powertrain warranty.
A fuel-operated heater (FOH) is available for vans equipped with the Duramax 6.6L to quickly provide heat to the vehicle interior in cold weather. This seamlessly integrated system is designed into the Express chassis, saving customers the time and labor of upfitting an aftermarket system. The electronically controlled, fuel-operated heater operates automatically, turning on and off within parameters that include outside air temperature, fuel level, coolant temperature and engine use. It features a self-contained, pressurized auxiliary coolant heater (with a surge tank) that uses diesel fuel to generate up to 17,200 Btu/h (5 kW) of heating energy.
The Duramax engine is backed by GM’s Hydra-Matic 6L90 heavy-duty six-speed automatic transmission featuring Tow/Haul mode.
A 4.8L V-8 is standard on 3500 models and generates 285 horsepower (212 kW) and 295 lb-ft of torque (398 Nm), while a 6.0L V-8, available in a flex fuel configuration, is standard on 4500 models and available on other models. It is rated at 342 horsepower (255 kW) and 373 lb-ft of torque (506 Nm). The 6.0L is also offered in a special version – engine code LC8 – with hardened valve seats for an available Dedicated Liquefied Petroleum Gas model (4500 models).
Each is part of GM’s legendary small-block engine family and designed for quiet operation, including:
Backing the engines’ quietness is the assurance of long-lasting performance. The engine family was validated under extreme conditions, with the 6.0L engine dynamometer-tested to the equivalent of 200,000 miles – 50,000 miles more than other engines in the family. The engines also feature many long-life engine components that can reduce maintenance intervals and costs. The iridium-tip spark plugs, engine coolant, accessory drive belt and sealing gaskets are some of these items.
Some of the stringent durability testing included cycling engines between the peak torque and peak horsepower rpm points – the equivalent of towing a heavy trailer up a steep grade – for 600 straight hours.
The engines are mated to the Hydra-Matic 6L90 six-speed automatic transmission.
Additional powertrain special features include:
Chassis and suspension
Cutaway models are built on a strong, ladder-type full frame architecture. Varying frame sections support the 139-inch, 159-inch and 177-inch wheelbases. Soft-mount body-mount “donuts” and bolts, which attach upfit bodies to the chassis, are available on all models.
All Cutaway models feature an independent short-long arm (SLA) front suspension, power steering and four-wheel disc brakes with four-wheel antilock. At the rear is a hypoid drive axle and multi-leaf springs.
