New transmission and safety technologies have been introduced to improve driveability and fuel consumption.
The new Volvo I-Torque driveline has a new automated gearbox to deliver 2800 Nm of torque at low engine revs, resulting in one of the quieter trucks on the road. Lower revs also means less fuel is used and less friction in the engine. The D13 engine is most efficient between 900 and 1200 revs per minute. To achieve the high power output, the new D13 Euro 6 engine, which produces 460 hp/2800 Nm, is combined with a new dual-clutch version of the automated I-Shift transmission. With the I-Shift 2 dual-clutch system there is no torque interruption, not even during gear changes. This results in the engine being able to operate in a narrow optimised band, producing faster acceleration and good driveability. I-Torque reduces fuel consumption by up to 4%.
Volvo Trucks has also developed “Collision Warning with Emergency Brake”, which is an advanced braking system equipped with early collision warning to prevent accidents caused by driver inattention. The system combines a radar and camera that work together to identify and monitor vehicles moving in front of the truck. It detects a vehicle that the truck will hit at its current speed and alerts the driver via a constant red light in the windscreen. If there is no reaction from the driver, the red light starts to flash and a beeping sound is generated. If there is still no reaction, the system activates the emergency brake and tries to stop the vehicle. The system can prevent a collision with a moving target at speeds of up to 70 km/hr (43 miles/hr). The system is available on the new Volvo FH Series. Emergency breaking systems will be a legal requirement in Europe by November 2015.
Collision tests have shown that the Volvo FH cab is safer than any previous Volvo cab. Laser welding of steel panels makes it possible to join two flat panels prior to moulding, resulting in each panel being customised for thickness and quality. The cab is also larger due to the A-pillars being more upright and the door and floor structure has been altered to offer more protection in an emergency. The windscreen used to be the emergency exit, but a roof hatch now serves this function. The Volvo FH also has larger windows and a clearer instrument panel, allowing the driver to spend more time watching the road. A comfortable bed ensures the driver is well rested, and other active systems such as Lane Keeping Support (LKS), Lane Changing Support (LCS), Adaptive Cruise Control and Driver Alert Support (DAS) assist the driver further. A Front Under-run Protection System (FUPS) prevents passenger cars from becoming wedged under the truck in fatal collisions. Protecting the driver and truck from criminals has also featured strongly during design improvements. Source: www.volvotrucks.com
