Subaru Impreza STI Cosworth CS400 2011 Sedan Car

The new Subaru Impreza STI Cosworth CS400 is the result of a collaboration of the most eagerly anticipated automotive lately. Cosworth the first native-road cars developed since 1996, the latest Impreza enthusiasts limited edition performance car offers a lifetime vibration, combined with exclusivity – the production will be limited to 75 cars.

Vehicles, Cosworth-tuned turbo car is one of the world’s most accelerative. The familiar 2.5-liter turbocharged engine with “Boxer Machine ‘is transformed to 33 percent more power to produce, largely rooted in the Cosworth Formula 1 experience is broad. The engine that drives all four wheels via a six-speed manual gearbox, is an impressive 400 horsepower and offers a new model reaches 62 mph in 3.7 seconds, to quarter mile in 12.75 seconds at a terminal speed of 107 mph cover. Top speed is limited to 155 mph.

The Subaru Impreza STI Cosworth CS400 offers a variety of options Cosworth engineered components in the engine, turbo, exhaust, suspension, brakes and wheels, plus a subtle improvements to the exterior and interior styling to create a performance car that is completely different height with everyday hatchback practicality.

Only the market in the United Kingdom in the form of duty-drive Subaru Impreza STi Cosworth CS400 is available in a choice of three exterior colors (Spark Silver, Dark Grey and San Remo red), and the price of £ 49,995 in- away.

Engine delivers 33 percent more power

In the heart of the new Subaru Impreza Cosworth is a revised version of the horizontally opposed engine famous Marque, Boxer’s all-aluminum. The ‘flat-four engine’ will be removed from the car, hand finished, and the internal components and a few additional items were replaced by the rate which is determined by Cosworth.

Like Boxer ‘all Impreza’ engines, Cosworth STI unit is equipped with two overhead camshafts per cylinder bank (DOHC) plus an Active Valve Control System (AVCS) variable valve timing to provide and improve low-speed traction.

The focus of the upgrade is to save the Cosworth engine improvements that are simple, efficient and as close as possible to the original design of the equipment to ensure reliability and easy maintenance on a regular Subaru dealer.

Internal upgrades include high-performance piston, which is manufactured using the same methodology as used for the Cosworth Formula 1 to make pistons. Special characteristics of carbon build-ups to reduce to minimize friction and reduce weight.

Forged connecting rods are made of high strength 4340 (EN24) steel and special Cosworth engine bearings offer a unique combination of design, metallurgy and engineering. Heavy cylinder head studs, high-performance multi-layer head gaskets and oil pump high pressure is also installed.

The final result is an enormous increase in torque above the reach of the rotation, and a significant improvement in acceleration gear. This will be the Impreza more manageable for everyday road use, but also a much sharper tool in the circuit.

New turbo and ‘breathe easy’ sewer

An entirely new turbocharging system function Cosworth to design a new compressor and wastegate actuator pressure to increase ratings and increase power.

A unique exhaust system was developed for the engine to “breathe more and deliver its full potential. tubular manifold, larger capacity and a larger diameter drainpipes to the evacuation of hot gas to accelerate. The first catalyst is a non-restrictive design and the tail of a larger exhaust gives the unique tone of the note.

After a thorough performance upgrade that Cosworth ECU re-map, the CS400 boxer engine 33 percent more power (400 horsepower at 5,750 rpm, compared to 300 hp at 6000 rpm for the standard Subaru Impreza WRX STI includes) and 542 Nm of torque, During a stay within the limits of the capacities of the original Impreza powertrain design.

Gearbox and All-Wheel Drive System

To handle the increased power of the Cosworth-tuned engine, six-speed gearbox and Subaru Impreza STi has requested carbon synchromesh on top three gears and clutch short throw for quicker shifts.

There is also a single-plate clutch with improved revised plate, brake pads and discs. Gearbox and final drive ratio has not changed.

Full time Cosworth Subaru’s All-Wheel-Drive transmission with front and rear with limited slip differential, a function for torque distribution of 50/50 after a standard, but an electronic torque split varies according to changing circumstances. Multi-mode Driver Control center differential with viscous coupling senses which axle has the better grip and variable split ratio in milliseconds according to distribute torque, so as to maximize traction and to minimize the possibility of wheel spin.

Fine-feathered

Improve handling of the Subaru Impreza Cosworth’s, steering feel and driver feedback – without sacrificing comfort – is the main objective for the development team.

Maintaining the original layout and main components Subaru suspension, Cosworth chassis and a team of engineers and technicians work with Bilstein Eibach order to adjust the ride / handling / steering package is ideally suited to the performance of the new models improve.

Eibach springs and Bilstein new special inserts, which are a unique damping properties, which are produced by Cosworth specifications of functions. Ride height lowered by 10 mm at the front.

The advantages of this cleaning is twofold. First, there is a great improvement in the quality generally drive Impreza making it easier to live with on a daily basis. Second, in-line behavior that is more focused and calm. Upgrade damping means less pitch and roll on into the corners, which means that a driver wants to go back to previous strengths and exploit the system symmetrical All-Wheel-Drive cars.

Upgraded racing brakes’ stopping power to increase

To match the speed of the new supercar Subaru Impreza Cosworth’s, AP Racing Cosworth the task of developing a more powerful front brake. A larger diameter (355 mm) ventilated discs are adopted, with six-pot calipers with racing-style custom Piston operate on a larger brake pads.

Difference in performance was immediate. Taking into account hard to help minimize blurring, which means that drivers can rely on effective retardation AP stop time after time.

The rear brake rotors Subaru Impreza WRX STI’s standard, the overall balance of the brakes and ABS system that the original is preserved.

“Stand-out look, plus new flywheels

Exceptional performance of the Subaru Impreza Cosworth prominently reflected in the company-’penampilan and standard Xenon headlamps. Reduced ride height and wider track gives the car a new attitude reinforced by the front bumper of the new forms, new fog lights, lattice top and bottom mesh and a new rear spoiler.

Cosworth badging secretly executed on the lower grille, front seat, brake calipers and a mat. Individually numbered plaque on the machine and frame. Subaru Impreza STI Cosworth CS400 Each comes with a certificate of authenticity number.

While the wheel of new models, the overall size similar to the Impreza WRX STI model was used to – 8.5 x 18 inches – they are lighter and stronger. The name “Pro Race” and the latest finish in anthracite wheels from Team Dynamics range is selected to be compatible with design of Subaru’s five men. This wheel has a 43 mm offset (SOA standard wheel offset is 55 mm) and expansion of rail with 12 mm – improved treatment and more cars fill the wheel arches are effective for more aggressive measures.

New wheels, high performance, low-profile Michelin tires grip SP3 selected for dry and wet road, endurance and a low noise level. 245/40 R18 tire size and tread is addressed.

Interior and equipment changes generous bonus

Within the new Recaro sports front seats, rear seats and steering wheel back all finished in black leather-branded Cosworth. CS400 is also different in the center console and the piano black finish accents, privacy glass and mounting.

Done in a more standard features than WRX STI model are: LED (light-emitting diode) taillights, front and rear electric windows, 10 speakers, six-disc radio / CD player, satellite navigation, Smart-entry and press the button Start with front, side and curtain airbags.

Full ownership advantages

The new Subaru Impreza STI Cosworth CS400 comes with a warranty of three years or 36 000 miles warranty, plus a cover of 12-year anti-corrosion warranty and three years of paint.

This is in addition to the three-year membership of Subaru Assistance – a comprehensive home and road repair and rehabilitation package in the UK and Europe administered by Mondial Assistance.
