The Japanese all-wheel drive specialist will be displaying an entire drivetrain at the show.

Subaru believes in its ‘boxer’ engines which are more compact than in-line units and provide a lower centre-of-gravity.

This reduces body roll for safer cornering and also enhances handling precision such as during a sudden lane-change manoeuvre on a motorway.

Due for its first vehicle application early next year, the Subaru ‘boxer’ turbo diesel is a highly rigid unit with low levels of noise and vibration.

Not only does this eliminate the need for a balancer shaft which counters uneven combustion pressures and general roughness, but Subaru’s first diesel is as compact as its petrol engines and combines strong pulling power at low engine speeds with high-rev throttle-response.
