The new Chevrolet Silverado with turbo four turned out to be more voracious than the V8 version.January 29, 2019
Last May, Chevrolet unveiled a new version of the Silverado pickup truck on the American market, which received a compact four-cylinder aluminum engine of the L3B series with a volume of 2.7 liters. We are talking about a 314 hp engine with a torque of 473 Nm, and which is equipped with a system for deactivating cylinders under load. This modification was to overshadow competitors in terms of efficiency, because neither the Ford F-150 nor the Ram 1500 is not equipped with engines with fewer than six cylinders.
When last year the car passed the EPA certification, it turned out that in the combined mode the new engine consumes 11.7 l / 100 km, which is less than the classic atmospheric V8 with a volume of 5.3 l (13 l / 100 km). However, American observers decided on their own experience to check whether the turbocharged engine really has better efficiency than the old engine with twice the volume and number of cylinders.
Our colleagues from the publication CarAndDriver conducted a 75-mile drive on the highway in order to check the stated characteristics of two pickups with engines of different concept in stable conditions. After the end of the test, the results gave a surprise: 2.7-liter turbo engine consumed an average of 13 liters of fuel, while the car with the V8 was packed in 11.2 liters.
Which of these can be concluded? According to colleagues, the 5.3-liter V8 engine produces 335 hp in the conditions of the highway, it works on a heavy pickup truck with a much lower voltage than the 2.7-liter four, and the fuel mixture is more efficient under these conditions for a motor with twice as much volume and a number of cylinders.
