A versatile vehicle with great hauling capabilities, the GMC Savana can easily carry up to 15 people and their cargo. It also provides the ideal foundation for those looking to upfit vans through an aftermarket manufacturer.
The 2015 Savana passenger van lineup is offered in 2500 Series – regular length with a 135-inch wheelbase – and the 3500 Series, which is available in regular (135-inch wheelbase) and extended (155-inch wheelbase) lengths. They can accommodate eight, 12 or 15 people and are offered in LS and LT trim levels.
The 2500 Series vans are rated at 8,600 pounds (3,901 kg) GVWR, and 3500 Series, which includes full-bodied cargo/passenger vans rated at 9,600 pounds (4,354 kg) GVWR with a standard 4.8L gas V-8 engine or an available 6.0L gas V-8; and 9,900 pounds (4,490 kg) GVWR with the available Duramax 6.6L turbo-diesel.
Standard and available features include:
There’s also a new exterior color choice for 2015: Emerald Green.

Savana powertrains – 6.6L Duramax diesel
The powerful Duramax turbo-diesel V-8 is offered in some Savana models, 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 (712 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.
When it comes to cold-weather performance, the Duramax uses microprocessor-controlled glow plugs 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; and it is backed with a five-year/100,000-mile powertrain warranty.
A fuel-operated heater (FOH) also 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 Savana 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.
Savana powertrains – gas engines
GMC Savana offers a choice of two gas engines: a standard 4.8L V-8 rated at 285 horsepower (213 kW) and 295 lb-ft of torque (400 Nm) and an available 6.0L V-8 rated at 342 horsepower (255 kW) and 373 lb-ft of torque (506 Nm). 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 and a fast-idle option makes it easier to run accessories at a work site.
The 6.0L is also offered in a special version with hardened valve seats for the available dedicated compressed natural gas model – the industry’s only CNG vehicle fully integrated at the factory, crash tested and backed by GM’s 100,000 mile/five-year transferable powertrain limited warranty. For Savana passenger van models, a three-tank system (RPO code UFM) provides a range of up to 200 miles and allows complete use of the cargo area. Savana cargo van models offer a four-tank system with additional range.
Chassis and suspension
The Savana is built on a strong, ladder-type full frame architecture. The frame features fully boxed sections for greater strength and rigidity, while extended and tapered front frame rails are used for improved crashworthiness. Also, additional tubular frame cross members are used to increase torsional stiffness.
All models feature an independent short-long arm (SLA) front suspension, with a 35mm front stabilizer bar. Two-stage, semi-elliptic multi-leaf springs are used in the rear suspension and help locate a semi-floating axle.
Other chassis and suspension features include:
Safety and crash-avoidance features
Savana is equipped with many safety features, including standard head curtain side air bags, which provide a higher level of protection in the event of a side impact or a vehicle rollover. Also, Enhanced Technology Glass (ETG), which provides superior occupant retention, is standard on 12- and 15-passenger models.
Additional safety features include:
