Car reviews - Toyota - LandCruiser 70 - 78 Series cab chassis utility
4 Apr 2002
TOYOTA introduced the 4.2-litre normally aspirated diesel engine in 1988 by fitting it to the LandCruiser 75 Series. Since that time the engine has been fitted to a range of LandCruiser vehicles in turbo and non-turbo format and has undergone several enhancements that culminate in the release of the 4.2-litre turbo-diesel, fitted as an option to the LandCruiser 78 Series. Toyota claims the turbo-diesel has 27 per cent more power and 33 per cent more torque than its naturally aspirated cousin. Toyota's direct-injection multi-valve SOHC engine delivers 122kW at 3400rpm and 380Nm of torque at 1400rpm, which places it ahead of the Nissan Patrol 4.2-litre turbo-diesel engine that produces 114kW at 3600rpm and 330Nm at 2000rpm. The 78 Series is a workhorse, and the turbo engine is built for work, maintaining its impressive 380Nm of torque across a wide rev range from 1400rpm to 2600rpm. Pulling power on some diesels is available across a narrow rev range but the LandCruiser does not fade when the revs continue to climb or force you to up-change to keep the engine operating at optimum revs for peak torque - this is a most noticable advantage on hill work. The engine emits the usual diesel rattle at low revs but there is a marked improvement in the level of vibration that reaches the cabin, and once the revs climb over 2000rpm the engine is surprisingly smooth. Toyota now fits snorkels to the air intake of all 78 Series LandCruisers, which makes taking it for a dip safer - and with a compression ratio of 18.5:1 a drop off water could cause a lot of damage.

Did you know?A Toyota LandCruiser based in Western Australian has broken the one million kilometre barrier. The vehicle has been used as a pilot for trucks carrying oversized loads, and despite travelling up to 900km a day for years, the 4.0-litre diesel has needed surprisingly little attention and is still performing reliably
