![]() All I-Shift AMTs come with I-See, an intelligent cruise control system that memorizes the topography of the road to optimize shifting and throttle applications to save fuel. of torque.Īll VNL models come standard with the Volvo I-Shift AMT, with the I-Shift with Crawler Gears available as an option. ![]() New VNL models spec’d with the D13 feature up to 500 horsepower and 1,850 lb.-ft. of torque, combined with an up to 2.5 percent fuel efficiency improvement compared with the previous D11 engine. New VNL Daycab and VNL 400 models equipped with the Volvo D11 deliver up to 425 horsepower and 1,550 lb.-ft. “These features added to the proven Volvo D-series foundation enable us to give customers the performance they want along with the efficiency their business requires.” “Volvo’s proprietary engine options in the new VNL series mean customers no longer have to choose between good fuel efficiency and good power,” Moore said. ![]() The new intake throttle enables a faster warmup when the engine is started. An available two-speed coolant pump also contributes to improved fuel efficiency as a result of reduced parasitic losses. The engines also feature a revised EGR flow sensor with a new double-wall casing to reduce condensation and soot buildup in cold weather, preventing downtime. A proven common rail fuel injection system improves fuel efficiency by enabling finer control and more accurate fuel injection. The 15-liter Cummins X15 is also available in the VNL series.Īll three Volvo engines feature the patented wave piston, which employs a uniquely designed piston crown with ridges to burn fuel more efficiently. ![]() Customers choosing Daycab and VNL 400 models also have the option of spec’ing the 11-liter Volvo D11 as an alternative. ![]() The VNL series comes standard with the Volvo D13 engine, with the D13TC available as an option. XE packages rely on Volvo’s fully integrated I-Shift automated manual transmission to downspeed the engine, enabling a cruise rpm up to 300 rpm less than the average truck sold today, saving fuel. “This robust system is completely mechanical and adds no additional routine maintenance to the engine.”Ĭustomers are able to pair the D13TC with Volvo’s XE – eXceptional Efficiency – powertrain packages. “Turbo Compound is a waste heat recovery system that uses a turbine to convert energy from the exhaust gases into additional torque on the crankshaft improving engine efficiency,” said John Moore, Volvo Trucks product marketing manager – powertrain. The 50 additional horsepower is fed directly to the crankshaft, resulting in up to a 6.5 percent improvement in fuel efficiency from the engine alone when compared with previous GHG14 D13 engine models. “Now, combined with an additional 1 percent fuel efficiency benefit from the improved aerodynamics of the new VNL series, customers spec’ing the D13TC will see up to a 7.5 percent improvement overall.”ĭesigned for customers with long-haul, steady-speed operations, the 13-liter Volvo D13TC utilizes turbo compounding technology that recovers energy typically wasted through the exhaust, converting it into useable mechanical energy that is transferred back to the engine. “Since their introduction, we’ve found our lineup of GHG 2017 engines – particularly the D13TC – to be the most fuel-efficient we’ve ever offered in North America,” said Göran Nyberg, president of Volvo Trucks North America. ![]()
