4WD Test - Toyota V8-D4D LandCruiser
With power and torque like this on offer, overtaking a truck on a mountain pass isn't an issue any more. In terms of agility and driving comfort, it is important to note that the steering is precise and that replacing the steering damper greatly improves the handling comfort. If you compare this engine to other top notch high power diesel engines from any other brand, even ones built by Toyota themselves, the power provided by the 1VD-FTV seems at first not to be too impressive. But the intentions and aims of this engine have been different from what you'd consider 'normal' high power diesel engine to be used in modern common passenger car.
One has to keep clearly in mind, under which conditions these engines will be used. This engine's normal working environment is the Australian outback or the deserts and wilderness of Africa. These are environments, which are as different as chalk and cheese when compared to European autobahns and American highways in particular. Most of the time these vehicles will be far, far away from the next service centre complete with computers and high-speed connection to the Internet to read out error messages and evaluate the cause of minor faults. These engines have only one duty. To function by all means - because 'Mobility Warranty' is not that useful in the outback...

The 1VD-FTV consists of a graphite iron engine block with aluminium alloy cylinder heads. Combustion air is lead through an intercooler, accelerated by a watercooled turbocharger and is fed to the intakes by two electronically controlled throttle-bodies (one for each cylinder bank). Cylinders are arranged in a 90-degree-V-shape. The crankshaft is equipped with seven counterweights and supported by 5 bearings. The engine block has been provided with a forceful stiffener to reduce mechanical vibrations. Pistons are also made from aluminium alloy with cooling ducts, piston crowns providing the combustion chamber. Piston skirts are coated to reduce friction loss. Injectors at the cylinder bottom spray engine oil direct to the bottom of the piston to improve cooling and lubrication. Piston rods are forged from high strength steel. Design features of the combustion chamber are: 4-valves and pivotal located magnet high-pressure injection nozzles to provide high power output and low emissions. The fuel injection system uses pilot injection to optimize power output and fuel-consumption. The glow plug is located between the intake-valves to optimise the start up performance of the V8 engine.
