Concern General Motors announced the release of a limited batch of full-size pickup trucks with a hybrid power plant eAssist: this year will be made 500 copies of the model Chevrolet Silverado and 200 twins GMC Sierra.
This is the third attempt of the GMC to introduce a hybrid drive on large pickups. For the first time it appeared on the machines of the year before last (GMT800) in the 2004 model year. GM loudly announced the “parallel hybrid”, but in fact it was a hybrid “soft”: built-in between the engine V8 5.3 and the gearbox, the starter-generator was responsible for restarting the engine after stopping the car and storing the recuperative energy in three additional lead-acid batteries under the rear seat (hybrid pickups were produced only with “long” cabs).
People advertised cars as a source of electric power for camping or driving auxiliary devices: for this purpose two additional electrical connectors were installed in the bodywork. Despite the declared fuel economy of 15%, the car, as they say, “did not go” – and eventually returned to the manufacturer under the procedure of repurchase.
On the pickups of the next generation of GMT900, they used a more advanced and complex Two-Mode Hybrid scheme: two electric motors with a capacity of 60 kW and an electromechanical variator with four fixed gears (joint development with DaimlerChrysler). Pickups Chevrolet Silverado 1500 Hybrid and GMC Sierra 1500 Hybrid with a power unit peak power of 384 hp (of which 337 hp was provided by the gasoline “eight” 6.0) could be moved both in combined mode and only on electric traction. The firm promised an “electric” maximum speed of 48 km / h, but in real life the speed rarely exceeded 15 km / h.
In 2013, the Two-Mode Hybrid program was canceled: buyers were not in a hurry to part with an additional three thousand dollars in the name of “passport” 11-percent fuel economy.
And now the hybrid Chevrolet Silverado and GMC Sierra are returning – so far only to California. And again in the form of “soft” hybrids, that is, with the BASIC eAssist JIEM system, which includes a 15 kW motor peak generator, a 0.45 kWh lithium-ion battery, a liquid-cooled inverter and an adapted “soft” from a hybrid hatchback Chevrolet Volt.
The electric motor manages the system of start-stop, and at acceleration and increased loads it gives up to 13 hp. and 60 Nm to help the gasoline “eight” 5.3 (360 hp). As a result, GM promises to reduce fuel consumption by 9%: 11.8 l / 100 km in a mixed EPA cycle vs. 13.0 l / 100 km for base pickup trucks with the same eight- penny “automatic”. But the extra charge for the hybrid makeweight is quite small – only $ 500.
But in the name of what all this hybrid circus with a ridiculous real effect? These are all strict environmental regulations of the State of California. They force manufacturers to reduce the average fuel consumption in the model range. Therefore, the presence of hybrid pick-up trucks in the scale is essentially nominal. At the same time, Americans are not interested in fuel economy with current oil prices. For example, the same JIEM not going to equip in the foreseeable future light versions of pickups Chevrol e t Silverado and GMC Sierra diesel engines, although on heavy modifications and competing trucks Ford F-150 and Ram 1500 they are used.
