  • 2016 GMC Sierra with eAssist

GMC Sierra’s new eAssist technology makes it one of the industry’s most innovative and capable trucks, helping it achieve up to 13 per cent greater city fuel economy and solidifying its segment-best ranking for V8 efficiency.

Starting this spring, the new eAssist system is exclusively available on the already well-equipped 2016 Sierra 1500 SLT crew cab 2WD model with the SLT Premium Plus package.

For 2016, GMC will monitor the market closely, producing 200 Sierra eAssist models for California, and adjust as appropriate moving forward.

The eAssist system includes a 24-cell, air-cooled 0.45 kWh lithium-ion battery pack, located under the center console (or front bench seat). It adds only about 100 pounds to the vehicle’s curb weight.

A compact induction motor, located on the accessory drive, provides 15 kW of peak regenerative capability, thanks to advanced software controls based on the Chevrolet Volt.

It performs like an electric torque booster, providing up to 44 lb/ft and up to 13 hp (9.7 kW) of additional boost in high load situations.

There’s also a liquid-cooled power inverter module located under the hood.

Compared to a comparable Sierra 1500 with a 5.3-litre/eight-speed powertrain, the Sierra with eAssist offers an EPA-estimated (US) 18 mpg city – a (US) 2 mpg improvement – while highway fuel economy improves (US) 2 mpg to (US) 24 mpg.

The combined estimate improves US) 2 mpg to (US) 20 mpg. The 5.3-litre eAssist V8 has a GM estimated 355 hp and 383 lb/ft of torque.

The maximum trailering rating is 9,400 lb and the Eaton locking rear differential is standard, for sure-footed traction on slippery surfaces.
