The new Boxer Diesel uses an advanced common-rail fuel-injection system, with the fuel being pressurised at 180 MPa before being fed into the common rail. This maximises efficiency, both in terms of power, fuel consumption and emissions.
Special, short-length solenoid injectors ensure the engine's width is no greater than that of the 2.0 litre 'boxer' petrol unit, despite the diesel's longer piston stroke.
The variable nozzle turbocharger ensures the correct boost throughout the engine's rev-range and its low centre-of gravity position under the engine and close to the catalytic converters increases environmental performance.
The Boxer Diesel meets Euro4 emission standards thanks to oxidation catalytic converters and a particulate filter.
A new feature for the Forester is a DPF (Diesel Particulate Filter). This reduces PM (Particulate Matter) - the cause of black smoke - to the minimum.
The new Boxer Diesel provides class-challenging performance thanks to its 147 PS at an ultra-low 3,600 rpm and a massive 258 lb ft torque at an accessible 1,800 rpm.
With a 'square' bore and stroke of 86mm and 16.3:1 compression ratio, the world's first Boxer Turbo Diesel provides effortless performance throughout a wide speed range, avoiding the breathless response of some diesels at high revs.
Top speed and the 0-100 kph times are among the best in the compact SUV class at 186 kph and 10.4 seconds while - even more importantly - in-gear flexibility leaves most competitors trailing thanks to strong mid-range torque and the carefully-chosen ratios of the new six-speed manual gearbox.
The new Subaru Boxer Diesel Forester boasts a new six-speed manual gearbox with optimised ratios for quiet, refined high-speed cruising and flexible low-speed manoeuvres.Published 19 November 2008
