Subaru will introduce a 4-cylinder horizontally-opposed (boxer) turbo diesel engine at the Geneva International Motor Show next month. This is not only its first diesel, but the first boxer turbo diesel. Subaru had announced at the 2006 Paris motor show that development of the turbo diesel was almost complete.
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.
This eliminates the need for a balancer shaft which counters uneven combustion pressures and general roughness. Subaru’s first diesel is as compact as its gasoline units and combines unusually strong pulling power at low engine speeds with high-rev throttle-response.
Subaru will unveil both the engine and a symmetrical all-wheel drive drivetrain as part of its press conference at the show on 6 March.
