Toyota’s new 2.8-litre D-4D turbo-diesel engine is expected to make its Irish debut in the Land Cruiser later this year.
It represents the first fruits of advanced new design and technology to achieve much higher fuel efficiency, lower emissions and quieter operation.
The new engine (1GD-FTV ) is the first in the world to benefit from 'Thermo Swing Wall Insulation Technology', making it one of the most thermally efficient on the market. It has a thermal efficiency rating of 44 per cent.
Although it is smaller than the 3.0-litre D-4D engine it is replacing, it offers 25 per cent more torque. Usefully, there is 11 per cent more torque available at low revs, and customers will appreciate a 15 per cent improvement in fuel economy.
As well as appearing in Land Cruiser, the engine is powering new Far Eastern market versions of Hilux. The same engine group will also feature a new 2.4-litre direct injection turbodiesel (2GD-FTV ).

New engine features
In testing, the new engines have proven their high thermal efficiency, quiet operation and powerful performance in worldwide locations, including extremely cold environments, where temperatures can fall to -40°C, and at high altitudes above 4,500 metres.
Toyota has also been able to make the engine catalyst 30 per cent smaller and has reduced the number of exhaust layouts from 18 to just three, simplifying the engines’ deployment worldwide and reducing the environmental burden.
