Land Cruiser V8 2012: Powertrains
The new Land Cruiser V8 2012 is available with a choice of a new 4.6 litre petrol engine or an upgraded, 4.5 litre turbodiesel unit, both of which are now EURO 5 compliant.
New 4.6 litre Petrol Engine
The Land Cruiser V8 2012's new EURO 5-compliant, 4608 cc petrol engine develops 234 kW/318 DIN hp at 5600 rpm and 460 Nm of torque at 3400 rpm via a 6-speed automatic transmission.
This enhanced power, fuel economy and emission performance has been achieved through the use of several new technologies.
Dual VVT-i (Variable Valve Timing-intelligent) to both intake and exhaust camshafts, significantly enhances engine performance. Numerous low-friction technologies improve engine efficiency to lower fuel consumption. A highly effective resin-type intake manifold with an Acoustic Control Induction System (ACIS) both saves weight and improves combustion efficiency. And a single-pump injection system speeds the warming of the catalysts to lower emissions.
Uprated 4.5 litre Turbodiesel
The new Land Cruiser V8 2012's refined, durable and powerful 4461 cc turbodiesel has been upgraded to comply with EURO 5 emission standard regulations.
In EURO 5 guise, mated to a 6-speed automatic transmission, the engine develops 200 kW/272 DIN hp at 3600 rpm, and an impressive 650 Nm of torque between 1600-2800 rpm.
The uprated engine features a new version of Toyota's common rail injection system, with G3 piezo injectors and a maximum injection pressure of 200 MPa, enhancing throttle response whilst complying to EURO 5 standards.
Noise and Vibration (NV) characteristics have been improved through the adoption of a pressure discharge valve to enhance pressure tracking performance, an injector top and pipe cover to reduce injection noise, and insulation placed between the injector and head covers to reduce noise from the head cover.
The engine now features a Diesel Particulate Filter (DPF) system, which allows a reduction in the weight and size of the main exhaust silencer, enhancing fuel efficiency. Allied to the adoption of an intermediate pipe to suppress exhaust system alignment variation, this reduction in silencer size has also further improved NV performance, reducing noise penetrating into the cabin.
