The LS is powered by a 4.8-liter V8 (285 horsepower, 295 pound-feet of torque) mated to a six-speed automatic transmission. Standard features include 16-inch steel wheels, a 60/40-split opening passenger door, 12-passenger seating (2-3-3-4 with a 50/50-split back row), air-conditioning, power windows and locks, a driver information display, vinyl upholstery and floor covering, GM's OnStar emergency communications, and a two-speaker audio system with an AM/FM stereo and an auxiliary port.
A tilt-only steering wheel and cruise control are standard on 3500 models and optional for the 2500. Opting for the extended-wheelbase 3500 adds rear air-conditioning, which is available as a separate option for the other LS models.
Stepping up to the LT adds front and rear chrome bumpers, remote locking and unlocking, cloth upholstery, carpeted flooring and rear air-conditioning. This trim also adds the tilt-only steering wheel and cruise control to the 2500.
Many of the features added by the LT are available on LS models as well. A bundle containing a 6.5-inch touchscreen with integrated rearview camera display, Bluetooth, a CD player, a USB port and a navigation system is available for any Express Passenger model. A rearview camera with display located in the rearview mirror can be ordered on any vehicle without the touchscreen. Other stand-alone options include power-adjustable heated mirrors, rear parking sensors, a heavy-duty locking rear differential, remote vehicle start, a leather-wrapped steering wheel, power-adjustable front seats, satellite radio and a 4G LTE Wi-Fi hotspot.
Some features and packages are available only when the appropriate body type is selected. The Paratransit package for 3500 extended-wheelbase models removes the rear seat and reverts to vinyl floor coverings. This body style can also be ordered in a 15-passenger (2-3-3-3-4 seating) configuration. Standard-wheelbase 2500 and 3500 models can be ordered in an eight-passenger (2-3-3) configuration.
Two additional powertrains are available on any body style. For hauling a high number of people, consider the 6.0-liter V8 (342 hp, 373 lb-ft) matched to a six-speed automatic transmission. If fuel efficiency is a priority, check out the 2.8-liter four-cylinder diesel engine paired to an eight-speed automatic.
