Subaru releases brand new boxer engine details

Subaru’s new boxer engine details have just been released and the main result is better fuel economy than the existing models whilst maintaining plenty of power and torque.

The new Subaru normally-aspirated (non-turbo) engine is the third generation developed by Fuji Heavy Industries, Subaru’s father company, and it’s the first brand new engine since 1989.
Subaru engines have always been robust, fairly powerful and very torquey especially when matched to high-geared ratios within Subaru’s all-wheel drive system. But the engines weak link has always been consumption and economy. It’s not that the engines are bad on fuel, they just consume a little more than the rivals.
Now though, Subaru and Fuji Heavy Industries have improved this area with indications noting a 10 percent increase in fuel economy. This was done through the use of lighter moving parts and an Active Valve Control system for the intake and exhaust.
The new 2.0-litre engine uses undersquare bore and stroke measurements too, meaning the pistons travel further than they are wide; 84mm bore and a 90mm stroke. This helps with torque and reduces the engine’s inclination to want to rev higher for more performance. Figures of 109kW and 196Nm are on offer.
Managing Director, Subaru Australia, Nick Senior said in a recent report,

“This is an exciting engineering development from FHI. They’re renowned for the durability of their engines and this new unit will take the sophistication to a whole new level that we’ll look forward to experiencing in some versions of our best-selling Forester next year.”

Subaru says the new engine will be available in both 2.0-litre and 2.5-litre capacities and will first go into the market with the Subaru Forester model year 2011, which will be launched early next year.

Subaru Impreza WRX 2011 is presented at the New York Auto Show.This new model has been improved and Subaru couldn`t just tweak the engine, they tweaked the body too. Subaru Impreza WRX 2011 has a wider track, with about 1.5″. The body modifications are completed with a new “face” and the 17″ wheels.
The new Subaru Impreza WRX 2011 has the same power specs as the previous model: 265Hp and 244lb-ft of torque.

These are very first spy shots of the Subaru and Toyota joint-developed rear-wheel-drive coupe. The test mule seen in the pictures looks like it’s sporting many body parts from the Legacy, albeit it’s apparent that coupe is much more compact in dimensions. We’re not so sure about the platform but in a previous official statement issued by the two Japanese carmakers, the yet unnamed coupes will be based on an all-new platform with power coming from Subaru’s range of boxer engines.

Judging by our experience that could translate to a modified version of the existing Impreza platform and 2.0 / 2.5-liter naturally aspirated and turbocharged engines. Needless to say that we can’t make any assumptions about the coupe’s appearance from the test mule pics. However, since both coupes are slated to enter production in 2011, expect a Toyota and Subaru concept version to appear sometime in 2009 with the production version making its official appearance in a major car show in 2010.

Subaru unwraps 2011 Subaru Impreza WRX with wider body design at New York Auto Show

Japanese carmaker Subaru unveils the 2011 Impreza WRX at the New York Auto Show. The design lines reveal the intention of the manufacturer to close the style gaps between the STI and the WRX models. The 2011 Impreza has a wider body and a more aggressive stance compared to the conservative look of the outgoing model.

The new Impreza WRX has a wider front and rear. It is also fitted with 17-inch alloy rims matched with 235/45R17 tires. Indeed the 2011 WRX is ready to pounce on the road compared to its older sibling.

The 4-door and the hatchback versions still sport the turbocharged 2.5L engine that can give out 265 horsepower. The engine is couped with a manual gearbox with a 5-speed configuration.
The wider body resulted to additional 33 pounds but it really doesn’t affect the performance of the car. The sedan will be 6.5 inches longer and logically offers more storage space than the hatchback version.

The design team also injected sharper bumper corners, wider fog lamps that are blacked out to blend well with the new profile. Some aerodynamic features were also added like the front spoiler on the lower lip.

Subaru Impreza Japanese Version

Developed around the concept of new and more refined designs for comfort plus performance, the third-generation Impreza features streamlined "5-door packaging", while it offers a rewarding and safe ride enhanced by Subaru Symmetrical AWD (All-Wheel Drive) with the Horizontally-Opposed engine and the newly developed chassis. The all-new Impreza intends to be a new global car that incorporates three core values: sophisticated styling; useful and convenient packaging; and a rewarding and trustworthy ride.

The new Impreza has been developed under the theme, "Providing a fascinating Subaru distinctive value." In accordance with Subaru's philosophy, the core mechanism of Subaru Symmetrical AWD (All-Wheel Drive) with a Boxer engine continues to provide an enjoyable ride with fun to drive handling for the driver, as it integrates performance with advanced safety and environmental considerations.

Impreza's Development Philosophy
Three key words were selected to develop the new Impreza, based on the concept of new and more refined designs for comfort. While advancing a sporty, safe and reliable drive that the Impreza series have consistently delivered, FHI has pursued to incorporate much higher levels of comfort and quality in the new model than any in its category offers.
* Sporty - achieving sophisticated design with its individual look, as well as an enjoyable ride with easy handling for the driver
* Casual - providing a stress-free comfortable ride under any driving conditions, as well as convenient and easy-to-use features
* Compact - securing ample, comfortable interior space in a compact body through streamlined packaging

Model Variations
* The Impreza 15S is the basic model built for handling and performance in harmony with fuel efficiency and environmental considerations.
* The Impreza 20S is the standard model featured more powerful engine performance, while providing outstanding stability supported by Symmetrical AWD.
* The Impreza S-GT is the Grand Touring model, offering a sporty drive with powerful turbo-charged engine performance.

Exterior design
A flowing line from the tip of the front hood through the rear window, as well as the short rear overhang, highlight the agility of the car. Sweeping character lines on both sides and well calculated panel curves reflect light and shadow in harmony. Impreza's sporty image is stressed in all models by projected front fenders and rear quarters; standard roof-mounted spoilers that house LED brake lights; and LED rear combination lamps that comprise brake lights, directional lights and back lights. The 3-dimensional design of the projector headlamps expresses functionality.

The Interior design
Aluminum-look insets in the center panels through door trim add a sporty feel and airiness to the car. The vehicle information display, which constantly shows outside temperature, average mileage and time on the digital clock, as well as a navigation screen and audio display, are placed nearer the top of the dashboard for improved visibility and functionality. New urethane materials are used in the front seat cushions to better absorb vibrations during a ride. The driver's seat incorporates newly developed seatback springs that support the driver's back and hips to help maintain a comfortable driving position. When the ignition key is turned on, the needles of three meters in the instrument panel swing up to their maximums and quickly fall back to their original positions - A Subaru tradition that - gives a boost of excitement for the driver starting the car. The instrumental panel also comes with an Info-Eco Indicator that lights up when running on low fuel consumption to encourage mileage-conscious driving. Two interior colors are offered on the 15S and 20S models: an ivory tone that accentuates openness and light; and off-black, which highlights both sportiness and elegance.

Powertrain
1.5-liter DOHC engine (15S) and 2.0-liter SOHC engine (20S)
The equal length/constant pulsation independent exhaust system substantially elevates exhaust efficiency through reduced interference between cylinders, which helps deliver optimal torque in various ranges of speed. The Active Valve Control System (AVCS) hydraulically controls timing in the intake valves and helps to increase combustion efficiency and improve low-end torque on the 15S. Various parts of engine employs friction-reducing technologies, including lowered load in the valve springs, mirror-surface machining, and molybdenum coating on the valve lifters. Fuel economy and emission reduction are greatly improved on the 15S.

2.0-liter turbo engine (S-GT)
The Dual Active Valve Control System (Dual AVCS) hydraulically controls timing in both the intake and exhaust valves, which helps increase combustion efficiency and improve low-end torque, and ensures linearly responsive acceleration to depressed pedal movement. The equal length/constant pulsation independent exhaust system substantially elevates exhaust efficiency through reduced interference between cylinders, which helps deliver optimal torque in various ranges of speed.

A tumble generated valve (TGV) has been installed in the intake manifold, boosting combustion efficiency by controlling the intake flow. It improves efficiency particularly at the time of engine ignition. Also adopted is a secondary air system that forces air into the exhaust port to burn out any gasoline remaining in it. The system helps eliminate harmful substances when the powertrain is still cool, and it promotes early activation of a catalytic converter.

Chassis / Body
The lower center of gravity, enabled by the Boxer engine, has been enhanced by mounting the engine front 22 mm lower on the chassis, thereby further improving stability. The strut-type front suspension is supported by newly designed front cross members. Employing box-shaped steel tubing, the new cross members further support the suspension, as well as improve crash worthiness. Thanks to these high-strength cross members, subframe parts have been largely eliminated, making the front floor section much lighter and enabling better handling and improved maneuverability. The newly designed double-wishbone rear suspension effectively absorbs shocks from road surfaces, ensuring high levels of ride comfort and agile handling as well as effectively lowering noise levels. The brake system employs tie rods for the brake booster, ensuring steady braking and control. The hill-start assist function maintains the braking function one second after the brake pedal is released in case of starting a car on a hilly road.
