3rd Generation Subaru Forester

Fuji Heavy Industries, the maker of Subaru automobiles, chose Christmas Day to launch its all-new Forester in Japan. The third-generation Forester is said to be a new-generation crossover SUV designed around the concept of ‘Best Package for Active Life’, which blends high levels of comfort, performance, versatility, and safety to create the best and most versatile vehicle for drivers and their families to enjoy an active lifestyle.

For the Japanese market, there are three versions, two powered by a 2.0-litre non-turbo Boxer (109 kW/148 ps, 191 Nm) engine (horizontally-opposed) and one with a turbo (169 kW/230 ps, 319 Nm). The engine is an upgraded version of the one used in the previous Forester. Significant changes include a newly-designed DOHC cylinder head and the use of an active valve control system (AVCS).

Low-end and mid-range torque are claimed to be improved, while better fuel economy and lower toxic emissions are achieved, primarily through design changes in the engine that generate a stronger tumble gas flow and raise air-fuel intake efficiency. AVCS is said to enhance power output, while fuel economy is achieved by improving combustion efficiency through the optimized timing of valve opening and closing. A design change in the cooling water channel around the spark plug further prevents engine knocking and also helps improve low-end and mid-range torque output. The turbo engine has a resin-based intake manifold with inner walls that are smoother and therefore less resistant to the intake flow. The weight is also reduced by 30% compared to the earlier manifold.
 
With the optimization of the diameter and length of the intake manifold, and the adoption of  the equal length/constant pulsation independent exhaust system, the engine’s intake and exhaust performance has been elevated. Two catalytic convertors have been placed in tandem. The layout enables the convertors to quickly heat up, which facilitates catalytic activation during engine startup and improves on emission reduction efficiency. The twin mufflers expand the muffler capacity, bringing noise levels down even lower and reducing exhaust back pressure.

4-speed automatic versions are equipped with the Sportshift gear selection that has an optimized final  gear ratio and torque convertor characteristics, as well as lower friction among part assemblies, improving driving performance and fuel economy. The N Control System automatically shifts the transmission back to neutral from driving positions after the brake pedal is depressed for some time. Gearshift operation is also said to be enhanced by the redesigned shift lever positions and the use of roller bearings.

The Active Torque Split AWD system is used for the automatic versions while those with manual transmissions come with the centre differential AWD system with viscous LSD (limited slip differential). Both AWD systems distribute optimal power to the wheels and the stability is further enhanced by Vehicle Dynamics Control (VDC) which is standards. Fed by information gathered by sensors that monitor vehicle and road conditions, the VDC coordinates the engine, transmission, and brakes in order to recover the vehicle’s position should unstable movements occur on a slippery road. 
 

The new Forester is not much bigger than its predecessor (110 mm taller excluding the roof rail, 45 mm wider) but with the wheelbase extended by 90 mm, cabin space and ride comfort are said to be better. Off-road capability is also improved by optimization of approach and departure angles, coupled with a generous ground clearance of up to 225 mm in some versions.

The Subaru Dynamic Chassis Control Concept (Subaru DC3) is something new. Integrating robust body structure with finely-tuned chassis elements, vehicle stability and excellent comfort are perfectly blended. It has a strut-type front suspension and newly-designed double-wishbone rear suspension which is mounted on the subframe. The steering gear box construction adopts a low-hysteresis cannon mount method that further enhances linear steering movements. Depending on the version, 16-inch or 17-inch wheels are used.

FHI expects to sell the new Forester at a rate of 2000 units a month in Japan at prices ranging from 1,995,000 to 2,572,500 yen (RM58,254 to RM75,117).
