Ford improves fuel economy with new truck range
The latest Ford F-Series Super Duty trucks look to be the greenest versions of the vehicles yet thanks to new diesel and petrol engine powertrains.
Now before you say that being the greenest truck is hardly worthy of an environmental stamp of approval, consider the strides that have been taken. The 6.7litre Power Stroke V-8 Turbocharged diesel engine, for example, averages an 18 per cent improvement in fuel economy for pick-up models and up to 25 per cent improvement for chassis cabs compared to 2010 models. Indeed trucks equipped with the basic 6.2litre V-8 petrol engine average a 15 per cent improvement in fuel economy when compared to the 2010 models.
There’s no compromise with power to achieve these improvements, however. The 6.7litre Power Stroke V-8 produces a best in class 997Nm of torque at 1,600rpm; while the new 6.2litre V-8 also boasts best in class numbers at 549Nm at 4,500rpm. Indeed the new diesel engine is also B20 biodiesel compatible, while the petrol engine is E85 compatible.
According to Al Bruck, the transmission engineering manager, the new transmission is a clean-sheet design that has been developed to handle increased torque and higher rotational speeds. It can deliver power to the wheels seamlessly and efficiently.
Among the enhancements that have been made to the transmission are an optimised shift and converter lock-up schedule; gearing and double-overdrive; optimised pumping pressure; optimised drainback to reduce spin losses; and a warmer operating temperature.
