Subaru Boxer Sports Car Architecture 2011

The Rear-Wheel Drive (RWD) Subaru Boxer Sports Car, which is currently under joint development with Toyota Motor Corporation (Toyota), incorporates into a new generation sports car with an ambition to provide driving pleasure to a wider range of customers. Thanks to its “front-engine, rear-wheel drive layout”, further lowered centre of gravity, compact and lightweight body and short wheel base, it delivers a new level of driving excitement with very unique crisp handling. The car will be the only mass-produced front-engine, rear-wheel drive sports car powered by a horizontally-opposed engine in the world, by making full use of an engineering masterpiece fusing Subaru’s sports car expertise ith Boxer engine performance and Toyota’s experience with RWD sports cars.
This new Subaru Boxer Sports Car is rooted in both companies’ engineering philosophy. Subaru’s engineering excellence, renowned for providing “Enjoyment and Peace of Mind” to its loyal customers, has been applied to the car’s development. Subaru’s idea of a front-engine, rear-wheel drive layout that was already used in the “Subaru P-1”, Subaru’s first prototype passenger car, as well as the expertise acquired during the development of the “Subaru XT” or of the fully-fledged speciality coupe model “Subaru SVX” were also incorporated into the model’s development. This Subaru Rear-Wheel Drive Sports Car, as Subaru’s first mass-produced front-engine, rear-wheel drive model, is expected to be produced first in spring 2012.

Subaru Boxer Sports Car Development Philosophy and the Rear-Wheel Drive Model> Ever since Subaru started building cars, Subaru’s objective has always been that of providing customers with enjoyment and peace of mind. Subaru’s development philosophy lies at the heart of each and every model ever produced, offering customers an assurance of driving “Confidence”. With such a consistent approach to the development of cars, Subaru has released a range of unique, innovative products to suit the requirements of customers at any point in automotive history, some of which include cars with Rear-Wheel, Front-Wheel and All -Wheel drivetrains.
Subaru Boxer Sports Car developed the Subaru P-1, its first prototype passenger car, in 1954. To create a car that delivered a comfortable ride, Subaru determined that it needed to have an excellent suspension system and a lightweight, rigid body. To achieve this, a front-engine, rear-wheel drive layout was used for the drivetrain and chassis, and a full monocoque design for the body – the first of its kind in Japan. Powered by a 1.5-litre engine, the classic 4-door sedan Subaru P-1 prototype was produced in its dozens. Although it never made it to the market, the Subaru P-1 was considered the forefront of innovative Subaru engineering. Some of the pioneering features found in the Subaru P-1 included an independent wishbone suspension system at the front, and a proprietary lightweight and rigid, full monocoque body design developed with the aid of aircraft technology born from the very origins of Subaru. Expertise and development philosophies that were raised during this time blossomed into a range of innovative ideas and advanced technologies that would later be applied to the development of the “Subaru 360”, Japan’s very own mini car for the public at large. These key concepts also found their way into the “Subaru 1000”, the earliest Front-Wheel Drive model to be powered by Subaru’s first Horizontally-Opposed Boxer engine, and other All-Wheel Dive (AWD) models used as the base platform for passenger cars. Indeed, these concepts continue uninterrupted to this day with the subsequent development of Subaru’s current distinctive crossover models.

Behind the new level of driving excitement and pleasure that the RWD Sports Car delivers is its new  platform technology, built around Subaru’s key component – the Horizontally-Opposed Subaru Boxer engine. A new platform has been developed based on Subaru’s authentic expertise in order to extract the maximum performance potential required of the RWD Sports Car. The “BOXER Sports Car Architecture” represents a proposal of Subaru’s new definition of driving excitement.
At the heart of this Technology Exhibit is Subaru Boxer engine. It is its lightweight, compact and low centre of gravity that lends itself to the level of driving excitement that Subaru is aiming for, and is without a doubt the most suitable engine for the RWD Sports Car. The Subaru Boxer engine can be constructed of aluminium owing to its compact and rigid engine design, making for a much lighter power unit. Its low centre of gravity provides a high level of driving stability and remarkable handling. Since the piston’s opposing movements inherently counteract each other, no balance shaft is needed. This cancels out excess vibrations and gives the engine a sprightly, sporty feel at virtually any engine speed. Needless to say, the Subaru Boxer engine has certain underlying characteristics that make it suitable for such sporty driving.
In the BOXER Sports Car Architecture, Subaru’s Boxer engine, which originally features a low centre of gravity and optimum weight balance, is even lowered and set back further towards the centre of the chassis. This feature also offers a low-profile sports car silhouette with its lowered engine hood design, resulting in a lowered driving position.

All these elements deliver excellent driveability, stability as well as handling delight. Optimised Chassis Layout for the RWD Sports Car – Another important factor that enables the RWD Sports Car to deliver driving performance befitting of a Subaru is its chassis. Rather than simply developing a frame and body that focuses purely on speed, development has been conducted to produce a chassis that delivers Subaru’s authentic driving characteristics: a sporty driving experience, an overall enjoyable ride, and stable drivability with driver confidence. The result is that the tyres follow every subtle variation in the road surface and that it responds exactly to the driver’s input. The Subaru Boxer Sports Car Architecture does not depend solely on engine power output – instead it maximises the potential of this newly developed chassis to achieve the fundamental characteristics of a rear-wheel drive sports car by delivering sporty performance as driver and vehicle work in unison, as well as providing agile response afforded by its short wheel base. Subaru’s distinctive suspension setup has been used, incorporating struts at the front, and a double-wishbone layout at the rear, to provide outstanding stability and control. When compared to other Subaru AWD models, the engine now sits even lower and further back in the engine bay. A lower centre of gravity, now located further toward the middle of the chassis itself, delivers a remarkable, natural feel when cornering, giving new level of driving excitement and handling delight to drivers. A short front overhang, matched with a shorter rear overhang reduces any yaw moment of inertia generated, and provides a higher level of stability and control, and handling performance of a pure sports car.

The Subaru Boxer Sports Cars platform technology adds a completely new package to complement Subaru’s existing AWD platform. This package will open Subaru’s renowned on-road performance to a broader range of customers. At the heart of this drivability lies Subaru’s engineering philosophy that constantly provides enjoyment and peace of mind. The “BOXER Sports Car Architecture” is a technical masterpiece that has been designed so that drivers can fully enjoy Subaru’s new approach to driving pleasure, with the full knowledge that they are constantly supported with the sense of confidence that only a Subaru can provide.

WRX Car Parts - Make Your Subaru WRX Unique

Out of all, the most impressive and fine Subaru WRX car parts is the turbo XS turboback exhaust. It is used for enabling the car to deliver high performance. It works by replacing the existing stock exhaust system. The turbo XS turboback exhaust mainly starts from the turbocharger to the rear muffler which also features a mandrel bent stainless 4 inch bellmouth downpipe which tapers down to 3 inch towards the flange. It can also be added into a 3 inch high-flow catalyst converter or also 3 inch catless race pipe which enters a 3 inch midpipe connected to a N1 style muffler fitted with a 4 inch titanium tip. It is a large piping diameter due to which it is one of the best available in the market. By installing it adds power so the exhaust turns out to be loud. These exhausts are made up of stainless steel which is long lasting. In this, the mounting points are factory cut/welded. There is no risk in buying these exhaust systems because they come with a 5 year warranty and they can be used widely for an off-road use.
One can find a Subaru WRX also with a custom designed Cobb Tunning SF intake which has several unique features for ensuring the optimal flow and performance. Cobb Tuning SF intake comes with several things such as a custom conical cloth air filter, CFD-designed velocity stack and also a unique air flow straightener grid which is specially designed for smoothing the incoming air flow which helps in precise readings. The main work of it is to eliminate the dead spots which are caused by the intake turbulence.
There are several other advantages also such as it saves weight, keeps incoming air cool, prevents heat soak and also eliminates any unsightly welds or other fasteners. These WRX parts are made after several researches and specially designed for the Subaru WRX. These parts can also be used with Stage 1 and Stage 2 Cobb Accessport maps and it can be cleaned with cleaning/oiling kit. These parts can be used for throughout the life of Subaru WRX. It also includes a support bracket which is powder coated black for ensuring secured installation.
If anyone wants to make their Subaru WRX more powerful and also reduce its turbo lag then they should go for the Cobb Tuning Downpipe. These WRX parts are designed for obtaining optimal performance and also durability which features a 304 Stainless Steel construction. The basic purpose of these parts is to reduce the lag and it also improves low-end torque and the biggest thing is that it offers great durability in high speed uses. These parts are mainly found in two versions, the street and race version. In the street version, a bellmouth section is available which helps in allowing exhaust gases to flow smoothly with the help of a 3 inch mandrel bent stainless steel piping into a metallic catalytic converter and it also not reduce the horsepower. On the other hand, the race versions do not include a catalytic converter and on its place an auxiliary O2 sensor bung is placed near the turbo. In the race versions, most of the parts are made up of stainless steel which includes hangers, flanges, O2 sensor bungs, casting and piping.
To increase the power of Subaru WRX, intake systems are widely used. There is no need to upgrade the ECU and on its place one can use a new turbos, intercoolers and boost controller. Subaru WRX car parts are made for enhancing its power and performance and there is no risk in using these parts. These car parts are affordable also.
