Toyota and Subaru Collaborate on 300 Series Land Cruiser.

And it Features a Revolutionary Quad Turbo X8 Engine

Following on from the success of their last collaboration on the BRZ / 86 sports coupe project, Toyota and Subaru have announced that they are again joining forces to deliver the next generation Toyota Landcruiser 300 Series.

The exciting news is that, as with the BRZ/86, Subaru will produce the engine / transmission and Toyota will deliver the body and 4wd suspension. Central to this is the development of an all new engine. Gone is the traditional V8 petrol and diesel variants. In their place is what Subaru calls their Project X8 engine, which is essentially 2 Subaru boxer diesel engines connected by a common driveshaft. The new engine will displace 5 litres, basically two 2.5l engines, and it will be boosted with quad variable geometry turbochargers.

Subaru engineers said the X configuration engine provides greatly reduced NVH levels while delivering higher torque over a greater rev range with prototype engines developing 1,100nm between 1,400 and 5,500 rpm.

The new engine incorporates a whole new fuel injection system.  Central to this is a super high pressure fuel pump which preheats the fuel before it is injected into the combustion chamber. This allows a variety of different fuels to be used including bio diesel mixes in excess of 80%. 

Even pure vegetable oil can be used if good old dino diesel is not available.

Transmissions will be beefed up versions of Subaru’s CVT automatic gearbox and symmetrical all-wheel drive. Low range will be provided by an updated version of Toyota’s transfer case as used in the 200 series. Suspension is expected to be a revised version of the KDS system with all 4 wheel independent suspension.

Toyota engineers said the X8 engine is shorter than the current V8’s which enabled them to reduce the length of the engine bay by 15cm, giving better all round vision to the driver especially in off road conditions.

While it stands to reason Toyota will continue with their hallmark Land Cruiser branding, it is expected Subaru will use the new model to rejuvenate its ailing Tribeca model range.
