Years ago, the diesel was the preserve of the truck to the other side of the pond. However, at the end of the century itself began to become hollow in the large pick-up truck, designed to drag heavy loads. Today, powers more than 400 HP and a torque of over 1,000 Nm is common in the segment heavy-duty. However, the diesel is still a novel technology in pick-ups like the Chevrolet Silverado 1500, the vehicle’s best-selling Chevrolet. After the launch of the Ford F-150 PowerStroke diesel and RAM 1500 EcoDiesel, it was time for Chevy to switch to a fuel with so much sense.
In Europe do not envisage a pick-up truck without a diesel engine, among other reasons due to the high cost of fuel and greater need for a high torque engine. Since then, we can’t afford a car as big as the Ford F-150, with petrol engines of nearly 400 horsepower in their guts (see test of the Ford F-150 Limited in the united States). But even in the united States are changing things. The modern diesel are efficient, powerful, and develop a huge pair engine. It was only a matter of time that the launch of a pick-up for diesel and the Chevrolet Silverado 1500 DuraMax 3.0.
All of the pick-up medium-sized u.s. already have a mechanical diesel. Something is going on in the U.S.
In his bowels is equipped with a new powertrain DuraMax, an engine of three-litre six-cylinder in-line. This propellant is manufactured by DMAX, a joint-venture between Isuzu and General Motors. It develops a maximum power of 277 BHP with a massive torque of 625 Nm, channeled to the gear train through a gearbox Hydra-Matic 10L80, ten relations and torque converter – this box is also used in vehicles from Ford, like the F-150 or the Mustang, and noted for great speed, as well as the ability to “skip” gears in an agile way if the situation so requires.
The engine is a new development, and features an aluminum block, in addition to connecting rods and forged pistons built into an alloy of silicon/aluminum. The engine is ready to withstand heavy abuse and on paper, is able to tow a trailer of up to four tons and a quarter. Within what are the pick-up “light,” americans, this figure is higher than that of the RAM EcoDiesel, but lower than that for the Ford F-150 PowerStroke, which is almost a ton higher. However, the highlight of this pick-up is for a low fuel consumption.
Chevrolet says that this pick-up meets the requirements for towing and daily use of 90% of customers pick-up.
In a cycle EPA urban, the version of propulsion consumes just 7.1 l/100 km, with a figure of 12.5 l/100 km in the urban cycle. On versions of all-wheel drive, the corresponding recognition is 8.1 l/100 km and 12.5 l/100 km Figures that correct for a car so heavy and not aerodynamic, especially if we take into account that the cycle us EPA is more realistic than its european counterpart.
