Volvo has unveiled a mighty 750hp, 3,550Nm version of the FH16 truck to handle the toughest transport tasks, with production planned to coincide with the 16-litre engine's 25th anniversary, next year.
 "With the Volvo FH16-750, we can offer a truck with absolute top performance, good fuel efficiency and extremely low emissions," states Staffan Jufors, president and CEO of Volvo Trucks.
The new engine is based on the same technology as Volvo Trucks' current 16-litre 700hp diesel power plant – an in-line six, with overhead camshaft, four valves per cylinder and unit injectors. However, it has been re-optimised for higher power and torque, while staying within existing fuel consumption figures.
The 750hp engine will be available in two versions: one for Euro-5 and the other for EEV (enhanced environmentally-friendly vehicle).
Beyond that, the transmission is, unsurprisingly, the Volvo I-Shift, although modified to handle the engine's high torque.
Also, the rear axle range encompasses assemblies for gross combination weights up to 250 tonnes. For fast long-haul duties, the recently introduced RS1360 solo axle looks like the most fuel-efficient choice.
As for the torque curve, the new 750hp engine produces 2,800Nm at 900rpm, beyond which it rises steeply to the peak of 3,550Nm at 1,050rpm and then levels out to 1,400rpm.
