GMC Sierra 2018 – pickup of class “K4” with rear-wheel or all-wheel drive. The debut of the restyled version of the third generation of the model took place in the summer of 2015.

The restyling definitely benefited the Sierra Regular Cab. A new radiator grille, new headlights with plenty of LEDs, redesigned bumpers and rear lights – all this made the appearance of the car more modern, but did not affect its brutality and massiveness. As for the interior, there were practically no changes, except for the modernization of the multimedia complex, which received support for Android Auto and Apple CarPlay.

Nevertheless, in the trim of the Sierra’s interior there is still a lot of soft plastic and leather, and in general, the materials used are of very high quality. The equipment is beyond praise. In total, many versions of the pickup are available to order, thanks to which each potential buyer can easily choose the one that most fully meets his specific requirements for a car of this type.

Under the hood, the GMC Sierra Extended Cab can be equipped with one of the EcoTec3 gasoline engines – a 4.3-liter V6, a 5.3-liter V8, or a 6.2-liter V8, producing 285, 355, and 402 hp respectively (413, 519, and 1037 Nm of torque). The engines work in tandem with a 6-speed or 8-speed automatic transmission. At the same time, the most powerful version of the pickup, the Denali, is equipped with a 6.6-liter turbo diesel V8 with 397 hp and 765 Nm of torque. With such a “heart,” the pickup weighing more than three tons accelerates from zero to 100 km/h in 7.7 seconds.
