Subaru’s Boxer Diesel engine now in Forester and Impreza

Subaru was trailling well behind in the green car league, not helped by its all-petrol 4×4 line-up, however the company’s new Boxer Diesel engine is changing all that. Already in the Legacy and Outback, it’s now set to appear in the new Forester and Impreza at the 2008 Paris Motor Show.

The Outback Boxer Diesel is already best in the ‘crossover’ class for economy and emissions, and now the Forester can claim the same title in the SUV sector, with 44.8 mpg combined and 167 g/km from the Forester 2.0D X.

The world’s first horizontally-opposed diesel engine for a passenger car has won widespread praise for its refinement, smoothness, sharp throttle-response and outstanding fuel economy.

Both the Forester and Impreza Boxer Diesels feature new six-speed manual gearboxes while the engine itself benefits from a new closed-type diesel particulate filter. The Forester 2.0D produces 147 PS and the Impreza 150 PS.

The engine’s benefits include exceptional compactness, light weight and a low centre-of-gravity which benefits handling agility and makes best use of the standard all-wheel drive system.

The new Forester Boxer Diesel goes on sale in the UK in late September and the Impreza Boxer Diesel in January 2009.

Also on display at the Paris Motor Show is the Subaru R1e, co-developed with the Tokyo Electric Power Company (TEPCO). Currently, 40 test cars are being tested in an area of Tokyo.

Another electric vehicle, Subaru’s G4e Concept, gives a hint at future developments and features the next generation of lithium-ion batteries which give a projected travel range of 200 km between charges.
